Description

The present invention relates to an arrangement for the axial support of two rotating or rotatable components by means of a circumferentially interrupted circlip which is supported or supported in at least one axial direction of the supporting member or / and arranged in a groove of the supporting member. Moreover, the present invention relates to a torque transmitting device with such an arrangement and a retaining ring for such an arrangement.

Arrangements are known from the prior art for the axial support of two rotating or rotatable components by means of a broken in the circumferential direction of the locking ring. That's how it describes DE 103 02 075 A1 a multi-plate clutch with an outer plate carrier and an inner plate carrier, which are rotatable with each other and are supported by means of a so-called snap ring in the axial direction to each other. In the outer plate carrier, an inner groove is provided, so that the snap ring is supported in both axial directions on the outer plate carrier. The inner plate carrier, however, is supported in the axial direction of the snap ring within the inner groove and thus also in the axial direction of the outer plate carrier. In order to prevent the snap ring from contracting under an unfavorable excitation of the entire system or due to the load acting thereon and jumping out of the inner groove on the outer plate carrier in the radial direction, protruding ramps are provided on the inner plate carrier, which in the assembled state are in the radial direction are arranged within the snap ring, so that the possibly radially contracting snap ring can be supported in the radial direction inwardly on the ramps to be held within the inner groove on the outer plate carrier. In other words, the ramps on the inner plate carrier to prevent a contraction of the snap ring in the radial direction inwardly by a positive support. Moreover, a stopper is provided on the inner disk carrier, which stop is arranged in the circumferential direction between the interruption of the snap ring limiting butt ends to prevent rotation of the securing ring in the circumferential direction within the inner groove. The known arrangement for axial support within the multi-plate clutch requires a relatively high production cost. The assembly of the locking ring within the multi-plate clutch is difficult. Moreover, it is questionable whether the radially inner ramps can be made so precisely that a secure support of the snap ring in the radial direction inward at this is possible without the snap ring is inclined and optionally further slides over the radially inner projection inward, but ultimately to jump out of the inner groove on the outer plate carrier.

From the EP 1 693 588 B1 is a multi-plate clutch device with a similar arrangement for axial support known. Thus, the known multi-plate clutch device has a plate carrier and an end plate which is in rotationally engaging engagement with the plate carrier, so that the plate carrier and the end plate are rotatable with one another. The end plate and the plate carrier are supported in the axial direction by means of a snap ring to each other, wherein the snap ring is arranged in an inner groove of the plate carrier and thus supportable or supported in both axial directions on the plate carrier. The end plate, however, is supported in the axial direction on the snap ring and thus in the axial direction of the plate carrier. However, the support here is not directly, but rather indirectly via a substantially annular disk-shaped securing element, which is arranged in the axial direction between the end plate and the snap ring. Protruding elements are provided in the axial direction of protruding elastic elements which are arranged in the assembled state of the multi-plate clutch in the radial direction within the snap ring. If the snap ring contract during operation in the radial direction inwardly, it is positively supported on the elastic elements of the securing ring to prevent further contraction of the snap ring and possibly jumping out of the snap ring from the inner groove on the plate carrier. Thanks to the elastically formed in the axial direction elastic elements, the assembly of the snap ring should be simplified. Nevertheless, this arrangement requires a more complex and space-intensive structure of the multi-plate clutch, especially since in addition to the supporting member in the form of the disk carrier, the component to be supported in the form of the end plate and the snap ring another component in the form of the annular disk-shaped securing element is required together with the elastic elements. A similar arrangement with the same disadvantages is further from the EP 0 692 642 A2 known, in which a similar securing element between the component to be supported in the form of a rolling bearing and a retaining ring is arranged, wherein on the securing element axially projecting catchers are arranged, which are arranged in the assembled state radially within the securing ring to this in a contracting thereof in the radial direction to support inwardly and thus to keep in the inner groove on the supporting member in the form of a wave.

It is therefore an object of the present invention to provide an arrangement for the axial support of two rotating or rotatable components of the generic type, on the one hand a secure arrangement of the locking ring on the supporting component and on the other hand, a simplified structure of the arrangement and a low production and assembly costs guaranteed. Moreover, the present invention has the object to provide a torque transmission device with such an advantageous arrangement for the axial support of two rotating or rotatable components with each other by means of a broken in the circumferential direction of the locking ring. Furthermore, the present invention has the object to provide a retaining ring for such an advantageous arrangement for the axial support of two rotating or rotatable components with each other.

This object is achieved by the features specified in the patent claims 1, 10 and 11, respectively. Advantageous embodiments of the invention are the subject of the dependent claims.

The arrangement according to the invention has two components which rotate or rotate with one another and which can be supported or supported axially against one another by means of a securing ring, preferably snap rings, interrupted in the circumferential direction. The interrupted securing ring can be supported or supported on the supporting component in at least one axial direction and / or arranged in a groove of the supporting component. For example, a plurality of circumferentially spaced-apart radial projections may be provided on the supporting component, on which the securing ring can be supported or supported in at least one axial direction. In addition, further circumferentially spaced-apart radial projections may be provided, on which the locking ring can be supported or supported in the opposite axial direction. Instead of the plurality of axial projections may also be provided in the circumferential direction closed circumferential radial projection, which can be spoken in two such radial projections of a groove. The locking ring has two axial projections which can be supported or supported on the component to be supported. In principle, more than two axial projections could also be provided on the securing ring, via which the securing ring can be supported or supported on the supporting component. It has been shown that the broken circlip can be held by the support on the two axial projections on the component to be supported even with unfavorable excitation of the overall system and / or under high load particularly safe in its support position and / or in the groove on the supporting component , Especially since due to the supported on the component to be supported axial projections of a change in diameter of the broken circlip, so for example, a contraction or expansion, is particularly effectively counteracted. Moreover, the production of the arrangement is significantly simplified, especially since corresponding axial projections can be relatively easily generated on the retaining ring. Also, no additional securing element, as for example in the EP 1 693 588 B1 or the EP 0 692 642 A2 is required, which simplifies the structure of the arrangement, reduces the number of parts and leads to a more compact design of the arrangement. Also can basically on the from the DE 103 02 075 A1 disclosed ramps are dispensed with the component to be supported, which support the locking ring in the case of a radially inner circlip or an inner groove on the inner circumference, which not only simplifies the production of the component to be supported, but also easier installation of the circlip within the arrangement for axial Support possible.

In a preferred embodiment of the arrangement according to the invention, at least one of the axial projections can be supported or supported in the axial direction on the component to be supported. It is preferred if both axial projections are supported or supported in the axial direction on the component to be supported. A support of the at least one axial projection in the axial direction of the component to be supported can be achieved relatively simple, so that the production is simplified, especially since the at least one axial projection, for example, can be supported simply on the securing ring facing side of the component to be supported, without inevitably a machining of the component to be supported is required. Moreover, the support of the at least one axial projection in the axial direction on the component to be supported has the advantage that a friction in the circumferential direction between the component to be supported and the retaining ring in the region of the at least one axial projection is increased, so that not only a rotation of the locking ring in the circumferential direction relative to the component to be supported and the supporting member difficult, but also a contraction or expansion of the locking ring, thus a diameter change thereof, is securely counteracted, so that the retaining ring is reliably held in its fixing position on the supporting member.

In a further preferred embodiment of the arrangement according to the invention, which is based on the embodiment described above, the at least one is in the axial direction the supported component supported or supported axial projection in the axial direction against the component to be supported prestressed or biased to reinforce the aforementioned advantages, namely a rotation of the locking ring and preventing or obstructing the contraction or widening of the securing ring.

According to a further preferred embodiment of the arrangement according to the invention, the at least one axial projection in the axial direction against the component to be supported is resiliently biased or biased to not only enhance the advantages described above, but also to simplify the mounting of the locking ring within the arrangement. The resilient bias in the axial direction against the component to be supported can be achieved, for example, in that the at least one axial projection is designed to be elastic in the axial direction. Alternatively or additionally, it is preferred in this case if the component to be supported in the axial direction via a spring device, such as a plate spring, is biased or biased against the retaining ring.

In an advantageous embodiment of the arrangement according to the invention, at least one of the axial projections, preferably both axial projections, is designed to be elongated transversely to the circumferential direction. In this way, the at least one elongated axial projection can be supported particularly securely while preventing the contraction ring from contraction or widening on the component to be supported, so that a secure fixing of the securing ring to the supporting component is possible regardless of the respective operating or loading condition of the arrangement or the securing ring is.

In a further advantageous embodiment of the arrangement according to the invention, the aforementioned elongated axial projection extends along a radial, thus perpendicular to the circumferential direction, to counteract contraction or expansion of the securing ring by supporting on the component to be supported.

According to a particularly advantageous embodiment of the arrangement according to the invention, the at least one elongated axial projection is inclined relative to a radial in the circumferential direction. For this purpose, the elongated axial projection may, for example, be rectilinearly elongated in order to be inclined at a predetermined angle with respect to the radial. However, it is also possible to provide a curved, bent or kinked elongated axial projection. Also, the elongate axial projection does not necessarily have to be circumferentially inclined over its entire length in the direction of extent with respect to the radial, but it is already helpful if the elongate axial projection is inclined in the circumferential direction at least over a portion of its length in the direction of extent with respect to the radial, although it is preferred is when the inclination is provided over the entire length of the elongated axial projection in the direction of extent thereof. In this embodiment, moreover, it is preferable that the elongated axial projection is circumferentially inclined with respect to a radial such that the elongated axial projection is inclined radially outward in the direction of interruption of the securing ring from the radial. If both axial projections are elongated and inclined with respect to a radial, then the inclination of the two elongate axial projections in the circumferential direction relative to the respective radials is thus preferably in opposite directions. Regardless of the particular embodiment selected, this embodiment has proven to be advantageous in that the inclination relative to a radial in the circumferential direction can effectively counteract contraction or widening of the securing ring.

In order to counteract a contraction or expansion of the locking ring in the installed state particularly safe, it has been found to be advantageous if the two axial projections each relatively close to the respectively associated, the interruption of the locking ring delimiting end of the locking ring and thus particularly close to the interruption of Circlips are arranged. For this reason, the two axial projections are arranged offset in a further advantageous embodiment of the inventive arrangement in the circumferential direction along a closed portion of the locking ring by an angle of more than 180 °, preferably at least 270 °, relative to each other.

As an alternative or in addition to the preceding embodiment, at least one of the axial projections, preferably both axial projections, is provided in a further preferred embodiment of the arrangement according to the invention at one of the locking ring associated end of the locking ring, thus relatively close to the interruption of the locking ring to a contraction or To counteract widening of the locking ring in its installed state. In this case, it is preferred if the end section extends over an angle of at most 30 °, particularly preferably at most 10 °, in the circumferential direction. It has proved to be particularly advantageous in this connection if the at least one axial projection, preferably also the other axial projection, is provided at the end of the end section facing the interruption or from the interruption facing end is formed, whereby also the manufacture of the locking ring is simplified.

In a particularly preferred embodiment of the arrangement according to the invention, at least one of the axial projections, preferably also the other axial projection, can be supported or supported in a form-fitting manner in the circumferential direction on the component to be supported. The positive support in the circumferential direction of the component to be supported in this case can be done waiving the previously indicated support in the axial direction of the component to be supported, but it is a combination of positive Abstützbarkeit or support in the circumferential direction and a supportability or support in the axial direction preferably to to ensure a secure arrangement of the locking ring on the supporting component. It is also preferred in this embodiment, the axial projection and the component to be supported in such a form that the axial projection is pressed or pressed due to the bias against the component to be supported in the surface of the component to be supported in order to effect the positive support and optionally on the Production of the engagement contour described in detail later can do without. Regardless of the particular embodiment selected, the sole or complementary positive support of the at least one axial projection in the circumferential direction on the component to be supported enables a contraction or widening of the securing ring to be effectively counteracted.

In a further preferred embodiment of the arrangement according to the invention, an engagement contour is provided on the component to be supported, into which the at least one axial projection can be introduced or introduced in the circumferential direction in the axial direction while achieving the form-fitting support. In order to simplify the assembly, the at least one axial projection in the circumferential direction in the axial direction latching into the engagement contour is introduced or introduced while achieving the positive support in the circumferential direction. This can be effected for example by the aforementioned bias of the at least one axial projection in the axial direction against the component to be supported, for which purpose the supporting member in the axial direction against the retaining ring biasing spring means provided and / or the axial projection in the axial direction to be elastic can. The engagement contour may extend only over a peripheral portion, but may also be closed or continuous in the circumferential direction.

In principle, the engagement contour can initially be formed by a separate engagement part, which was subsequently attached to the component to be supported. However, in order to reduce the production cost and to achieve a particularly compact construction of the arrangement, the engagement contour is formed integrally with the component to be supported in a further advantageous embodiment of the inventive arrangement. It is preferred if the engagement contour is embossed or stamped in the component to be supported.

In a further particularly preferred embodiment of the arrangement according to the invention, the at least one axial projection can be introduced into the engagement contour in at least two positions in the circumferential direction relative to the engagement contour. In this case, it is preferred if the at least one axial projection can be introduced into the engagement contour in significantly more positions in the circumferential direction relative to the engagement contour. In this embodiment, the assembly is simplified, especially since the retaining ring does not have to be arranged in only a predetermined rotational position relative to the component to be supported and thus also to the supporting component. Moreover, this allows certain manufacturing tolerances to be compensated for without introducing the at least one axial projection into the engagement contour. Thus, the broken retaining ring can be contracted for the purpose of radially inner mounting, for example, and introduced into the supporting member, before the broken circlip is relaxed again, so that this expands. When expanding, the at least one axial projection mutatis mutandis independently that position relative to the engagement contour, in which this can engage securely in the engagement contour or engages. In this embodiment, it is preferred if the at least one axial projection can be introduced stepwise or / and latching into the engagement contour, wherein the latching behavior can take place in the manner already described above.

To realize the aforementioned at least two relative positions of the at least one axial projection to the engagement contour, the engagement contour in a further advantageous embodiment of the inventive arrangement at least two circumferentially successive engagement recesses, in which the at least one axial projection in the axial direction, optionally stepwise or / and latching, einbringbar or introduced. The engagement depression mentioned here can be, for example, an engagement recess or an engagement hole, wherein an engagement hole can be supported or supported in a form-fitting manner in the circumferential direction only on the component to be supported Axial projection may be preferred, while an engagement recess, thus engaging with a bottom, may be preferred if the axial projection should be supportable or supported both in the axial direction and in the circumferential direction of the component to be supported. The engagement recesses are also preferred in that they develop a lower notch effect than the through engagement holes. Nevertheless, a combination of engagement recesses and engagement holes may be provided, for example, one axial projection may be associated with one or more engagement holes, while the other axial projection is associated with one or more engagement recesses.

In a further preferred embodiment of the arrangement according to the invention, the engagement recesses are formed transversely to the circumferential direction elongated, not only to achieve a secure form-fitting support in the circumferential direction, but also to compensate for any tolerances and to simplify the installation of the locking ring. In this case, it is preferable for the engagement recesses to extend along a respective radial or to be inclined relative to a respective radial in the circumferential direction. Again, an inclined elongated engagement recess may be a straight, curved, bent, or kinked engagement recess, as previously discussed with reference to the axial projections. Also, the inclined elongated engagement recess is preferably inclined such that the elongated engagement recess is inclined radially outwardly following the interruption of the locking ring from the radial to counteract contraction or expansion of the installed locking ring. The axial protrusions associated with the respective elongated engagement recess do not necessarily have to be elongated transversely to the circumferential direction as well, but such a design has proven to be advantageous with regard to a secure prevention of contraction or widening of the securing ring.

In a further advantageous embodiment of the arrangement according to the invention, at least one of the axial projections, preferably also the other axial projection, is elastically formed in the axial direction. As a result, for example, the aforementioned bias of the axial projection in the axial direction against the component to be supported or / and the latching engagement in the engagement contour can be achieved or enhanced. Moreover, the circlip can be pressed during assembly under elastic deformation of the axial projections in the axial direction against the component to be supported, which significantly simplifies the assembly.

In a further advantageous embodiment of the arrangement according to the invention, at least one of the axial projections, preferably also the other axial projection, is integrally formed with the securing ring in order to simplify the manufacture of the securing ring and the assembly of the arrangement.

According to a further advantageous embodiment of the arrangement according to the invention, at least one of the axial projections, preferably also the other, tongue-like, wherein the tongue-like axial projection is preferably provided at the end of the end portion or formed from this end.

In a further preferred embodiment of the arrangement according to the invention, at least one of the axial projections, preferably also the other, is tapered in the direction of the component to be supported by reducing a contact area between the at least one axial projection and the component to be supported.

According to a further particularly advantageous embodiment of the arrangement according to the invention, the at least one axial projection, preferably also the other, has a corner region with an edge, wherein the axial projection can be supported or supported via the edge on the component to be supported.

In order to prevent a contraction or expansion of the built-in locking ring, at least one of the axial projections, preferably also the other, is formed to form a linear contact area between the at least one axial projection and the component to be supported.

The arrangement of the invention unfolds its advantages both in a radially inner circlip as well as in a radially outer circlip formed circlip, in a further advantageous embodiment of the inventive arrangement, however, the circlip is arranged as a radially inner circlip on the supporting component.

The arrangement of the invention unfolds its advantages regardless of whether the broken circlip is disposed in an outer groove or inner groove of the supporting member. In a further advantageous embodiment of the arrangement according to the invention, however, it is preferred if the groove of the supporting member, in which the broken securing ring is arranged, is an internal groove.

According to a further advantageous embodiment of the arrangement according to the invention, the broken securing ring is designed as a so-called snap ring.

In the figures, the opposite axial directions 4 . 6 , the opposite radial directions 8th . 10 and the opposite circumferential directions 12 . 14 the arrangement 2 indicated by corresponding arrows, the circumferential directions 12 . 14 can also be referred to as directions of rotation. The arrangement 2 or their components are in the circumferential direction 12 . 14 around one in the axial directions 4 . 6 extending axis of rotation 15 rotatable or rotatable.

The order 2 has two rotating or rotatable components 16 . 18 on, namely a supporting component 16 and a component to be supported 18 , wherein the component to be supported 18 in the axial direction 4 by means of a circumferential direction 12 . 14 broken circlip 20 on the supporting component 16 can be supported or supported.

The supporting component 16 extends substantially tubular in the axial direction 4 . 6 and has one in the axial direction 4 facing opening with an opening edge 22 on. In the opening edge 22 are several in the axial direction 4 . 6 extending cuts 24 provided, with the incisions 24 in the circumferential direction 12 . 14 equally spaced and in the present example four cuts 24 are provided. Moreover, they are near the opening edge 22 , here directly to the opening edge 22 adjacent, several in the radial direction 10 inwardly protruding approaches 26 provided by forming the supporting component 16 were generated in this area, with the protruding approaches 26 preferably in the circumferential direction 12 . 14 evenly spaced from each other and / or to the incisions 24 are arranged offset. In the present example, there are four prominent approaches 26 intended.

The component to be supported 18 or at least a portion thereof is formed substantially annular disc-shaped, wherein on the radial direction 8th outwardly facing edge of the component to be supported 18 several in the radial direction 8th protruding rotary driver 28 are provided. In the illustrated embodiment, by way of example, four rotary drivers 28 intended. The component to be supported 18 is in the axial direction 6 by the axially facing opening of the tubular supporting member 16 such in the supporting component 16 pushed in that the rotary driver 28 while providing a rotational drive connection in the radial direction 8th out into the cuts 24 extend, wherein the component to be supported 18 is dimensioned or formed such that this in the axial direction 6 at the in the radial direction 10 inward protruding approaches 26 can be pushed past. In the installed state, the component to be supported has 18 one in the axial direction 6 facing back 30 and one in the axial direction 4 facing front 31 on.

The circlip 20 , which is preferably designed as a so-called snap ring, is also in the axial direction 6 through the in the axial direction 4 facing opening of the supporting component 16 in the supporting component 16 introduced, in such a way that the retaining ring 20 in at least one of the axial directions 4 . 6 , here the axial direction 4 , about the protruding approaches 26 on the supporting component 16 can be supported or supported. Consequently, the component to be supported is 18 in the axial direction 4 with its front side 31 on the circlip 20 supportable or supported while the circlip 20 about the protruding approaches 26 in the axial direction 4 on the supporting component 16 is supported, so that an arrangement for the axial support of the component to be supported 18 on the supporting component 16 in the axial direction 4 is created. Here is the component to be supported 18 in the axial direction 4 against the circlip 20 resiliently biased, in the illustrated embodiment by means of a spring device 32 done here, between the back 30 of the component to be supported 18 and another section 34 the arrangement 2 is arranged, the section 34 at least in the axial direction 6 on the supporting component 16 fixed or supported. In the illustrated embodiment, the spring device is 32 to a plate spring, but there are basically other spring devices in question.

In the illustrated embodiment, the supporting component 16 by way of example from the output side of a torsional vibration damper 35 formed within a drive train of a motor vehicle, while the component to be supported 18 is formed by a drive plate, which optionally acts as an input side of a coupling device or can act. Alternatively, the supporting component 16 also the input side of the torsional vibration damper 35 form while the component to be supported 18 is designed as a drive plate. The use of the arrangement 2 however, is not intended to be used in conjunction with a torsional vibration damper 35 limited. On the contrary, such a torque transmission device can also have a clutch device, preferably a multi-disc clutch device, in which the supporting component 16 a plate carrier is, while the component to be supported 18 may be an end plate or drive plate associated with the plate carrier and possibly thus in rotationally driving connection. Moreover, there are a variety of other uses of the arrangement 2 within a torque transmission device for the drive train of a motor vehicle conceivable or advantageous.

The circlip 20 is essentially annular disc-shaped and has an interruption 36 in the circumferential direction 12 . 14 on, being the interruption 36 in the circumferential direction 12 . 14 from the ends 38 and 40 of the circlip 20 is limited, with the ends 38 . 40 can also be referred to as so-called butt ends. The interruption 36 allows contraction of the locking ring 20 in the radial direction 10 inside, thus a diameter reduction of the locking ring 20 by removing the ends 38 . 40 in the circumferential direction 14 respectively. 12 be moved towards each other, so that the circlip 20 in the axial direction 6 at the protruding approaches 26 can be passed over in order to reach its desired position in the axial direction 4 . 6 again in the radial direction 8th expand and in the axial direction 4 at the protruding approaches 26 of the supporting component 16 be supported or supported.

The circlip 20 has two in the axial direction 6 protruding axial protrusions 42 . 44 on, on the component to be supported 18 in the axial direction 6 , more precisely on the front 31 of the component to be supported 18 , abstützbar or supported, as in particular the 4 can be removed. Here are the two axial projections 42 . 44 in the circumferential direction 12 . 14 along a closed section of the circlip 20 by an angle α of more than 180 °, preferably at least 270 °, arranged offset relative to each other. So is the axial projection 42 at one of the interruption 36 or the end 38 associated end portion 46 of the circlip 20 provided, wherein the end portion 46 over an angle β of at most 30 °, optionally of at most 10 °, in the circumferential direction 12 . 14 extends. In the illustrated embodiment, the axial projection 42 at the interruption 36 facing the end 38 of the end section 46 provided or from this end 38 educated. Correspondingly, the axial projection 44 at one of the interruption 36 of the circlip 20 or the other end 40 associated end portion 48 of the circlip 20 provided, wherein the end portion 48 preferably over an angle γ of at most 30 °, optionally of at most 10 °, in the circumferential direction 12 . 14 extends.

Moreover, the axial projections 42 . 44 each at a peripheral portion 50 respectively. 52 disposed opposite to an intermediate peripheral portion 54 in the axial direction 4 and thus opposite the front 31 of the component to be supported 18 is reset, with the axial projections 42 . 44 starting from the recessed peripheral portions 50 . 52 in the axial direction 6 stand out to the front 31 of the component to be supported 18 be supported or supported. In this case, the axial projections 42 . 44 in the relaxed state of the circlip 20 outside the arrangement 2 also in the axial direction 6 over the intermediate peripheral portion 54 be formed protruding. It should be noted at this point, however, that the peripheral sections 50 or and 52 not necessarily opposite to the intermediate peripheral portion 54 must be reset, but the peripheral sections 50 . 52 and 54 also be arranged in a common plane from which the axial projections 42 . 44 protrude, which then in the axial direction 4 . 6 should be elastic. However, the embodiments shown have proven to be particularly advantageous.

Like from the 1 to 4 can be seen, the axial projections 42 . 44 in the axial direction 6 on the front side 31 of the component to be supported 18 supportable or supported. Here are the axial projections 42 . 44 in the axial direction 4 . 6 resilient against the component to be supported 18 prestressed or prestressed. In the illustrated embodiment, the bias of the axial projections takes place 42 . 44 on the one hand on the component to be supported 18 in the axial direction 4 against the circlip 20 biasing spring device 32 and on the other hand, in that the axial projections 42 . 44 in the axial direction 4 . 6 are elastically formed. Thus, the axial projections 42 . 44 resilient against the front 31 of the component to be supported 18 biased when the component to be supported 18 by the way, with the front 31 at the intermediate peripheral portion 54 is supported, as is the case in particular 4 can be removed.

The two axial projections 42 . 44 are transverse to the circumferential direction 12 . 14 formed elongated, with the elongated axial projections 42 . 44 each along a radial 56 . 58 extend. Also, the axial projections 42 . 44 in the direction of the component to be supported 18 , thus in the axial direction 6 , while reducing a contact area 60 between the respective axial projection 42 respectively. 44 and the component to be supported 18 tapered trained. More specifically, the axial protrusions 42 . 44 one corner each 62 with an edge 64 on, over which the respective axial projection 42 . 44 on the component to be supported 18 or the front 31 of the component to be supported 18 can be supported or supported. Although not in 4 shown, so can the corner areas 62 be formed such that the axial projections 42 . 44 due to the bias in the surface 31 can be pressed or pressed in order to also support or Abstützbarkeit in the circumferential direction 12 . 14 to effect. The axial projections 42 . 44 are under formation of a linear contact area 60 between the axial projection 42 respectively. 44 on the one hand and the component to be supported 18 on the other hand trained. The axial projections 42 . 44 that are at the respective end 38 respectively. 40 the end sections 46 respectively. 48 provided or from the respective end 38 respectively. 40 are formed, are also tongue-like on the retaining ring 20 provided, wherein the axial projections 42 . 44 integral with the retaining ring 20 are formed.

Should the arrangement 2 be excited unfavorably during operation, so that the vibrations of the arrangement 2 or even on the circlip 20 acting stress a contraction of the locking ring 20 in the radial direction 10 causes, so cause the effect in the axial direction 6 on the front side 31 of the component to be supported 18 supporting axial projections 42 . 44 in that an approximation of the opposite ends 38 . 40 in the circumferential direction 12 . 14 and thus a contraction of the locking ring 20 prevented or at least impeded. Thus, the formation of the securing ring allows 20 a secure fixing of the safety ring 20 in which in the figures shown desired position and shape of the supporting component 16 ,

The 5 and 6 show a second embodiment of the arrangement according to the invention 2 , wherein the second embodiment substantially corresponds to the first embodiment, so that only the differences will be discussed below, the same reference numerals are used for the same or similar parts and the remainder of the description applies otherwise.

Like from the 5 and 6 it is visible at the front 31 of the component to be supported 18 an engagement contour 66 intended. The engagement contour 66 has several in the circumferential direction 12 . 14 successive engagement depressions 68 on, which are formed in the illustrated embodiment as engagement recesses. Alternatively or additionally, the engagement recesses 68 However, also be designed as engagement holes. The engaging depressions 68 are arranged such that the two axial projections 42 . 44 each in the axial direction 6 in the engaging wells 68 can be introduced or introduced. Thanks to the circumferential direction 12 . 14 successive engaging depressions 68 This can be done by expanding the locking ring 20 after contraction and introduction into the supporting component 16 stepwise or stepwise, with the axial projections 42 . 44 due to the bias of the spring means 32 and / or due to the elastic formation of the same in the axial direction 4 . 6 latching into the engagement recesses 68 can be introduced or introduced. Like the axial projections 42 . 44 themselves, are also the engaging depressions 68 transverse to the circumferential direction 12 . 14 formed elongated, with the engagement recesses 68 each along a radial 56 . 58 extend.

The engagement contour 66 is integral with the component to be supported 18 formed, it is preferred if the engagement contour 66 in the front 31 of the component to be supported 18 embossed or stamped. Although the engagement contour 66 in the illustrated embodiment, only over a peripheral portion of the component to be supported 18 extends, it should be noted at this point that the engagement contour 66 also in the circumferential direction 12 . 14 be closed circumferentially or continuously formed to a mounting of the locking ring 20 in any rotational position relative to the component to be supported 18 or the supporting component 18 to enable.

Due to the fact that the two axial protrusions 42 . 44 in the axial direction 6 , possibly latching, in the engaging recesses 68 the engagement contour 66 can be introduced or introduced, they are in the circumferential direction 12 . 14 positive fit on the component to be supported 18 supportable or supported, allowing a contraction of the locking ring 20 in the radial direction 10 is counteracted even safer inside, as is the case in the first embodiment, especially the interruption 36 facing ends 38 . 40 can be more effectively prevented from each other in the circumferential direction 12 . 14 to approach. Also, the axial projections 42 . 44 thanks to the large number of engagement recesses 68 each in at least two positions in the circumferential direction 12 . 14 relative to the engagement contour 66 in the engagement contour 66 or their engagement recesses 68 be introduced, causing the axial projections 42 . 44 can choose the most favorable position, possibly taking into account any manufacturing tolerances.

As part of the assembly, the circlip 20 initially in the radial direction 10 contracted, with the ends 38 . 40 in the circumferential direction 12 . 14 approach each other. Subsequently, the thus contracted retaining ring 20 in the supporting component 16 introduced, with the circlip 20 in the axial direction 6 against the component to be supported 18 is pressed. In this case, the axial projections 42 . 44 already in the axial direction 4 elastically deformed or bent. Reached the circlip 20 its axial nominal position, optionally after moving the component to be supported 18 in the axial direction 6 against the spring force of the spring device 32 so can the contraction of the circlip 20 be terminated so that the circlip 20 again elastically expands. As a result, the axial projections move 42 and 44 in the circumferential direction 12 . 14 relative to the engagement contour 66 in the manner of ratchet teeth until the circlip 20 its maximum possible diameter assumes by the circlip 20 in the radial direction 8th outward on the supporting component 16 is supported, wherein the axial projections 42 . 44 ultimately in an intervention recess 68 the engagement contour 66 intervention. Consequently, the assembly is simplified, wherein in the radial nominal position of the securing ring 20 in the engaging wells 68 engaging axial projections 42 . 44 a contraction of the circlip 20 in the radial direction 10 inside during operation even with unfavorable excitation of the arrangement 2 prevent or at least hinder.

The 7 and 8th show a third embodiment of the arrangement according to the invention 2 which is essentially the first embodiment according to the 1 to 4 , so that only the differences will be discussed below, the same reference numbers will be used for the same or similar parts and the remainder of the description applies otherwise.

In contrast to the first embodiment, the elongated axial projections 42 . 44 at least in part, here completely, opposite the Radial 56 respectively. 58 in the circumferential direction 12 . 14 inclined, as indicated by the angle 6 is indicated. Here is the elongated axial projection 42 in the radial direction 8th outwards in the circumferential direction 14 and thus in the direction of the interruption 36 or the end 38 of the circlip 20 opposite the radial 56 inclined. The elongated axial projection 44 is, however, in the radial direction 8th outwards in the circumferential direction 12 and thus in the direction of the interruption 36 or the end 40 of the circlip 20 opposite the radial 58 inclined. From the foregoing description it is further apparent that the axial projections 42 . 44 in the opposite direction to the corresponding radials 56 respectively. 58 are inclined.

It has been shown that by the inclination of the axial projections 42 . 44 a contraction of the here as in the radial direction 10 internal safety ring 20 can be counteracted even better than is the case in the first embodiment. This would apply in a similar way, if the retaining ring 20 as a radially outward locking ring on the supporting component 16 would be arranged. Also, the axial projections 42 . 44 preferably inclined so that also the respective associated contact area 60 is inclined in a corresponding manner.

The 9 and 10 show a fourth embodiment of the arrangement according to the invention 2 , which are essentially the embodiment according to the 7 and 8th , so that only the differences will be discussed below, the same reference numbers will be used for the same or similar parts and the remainder of the description applies otherwise.

The fourth embodiment according to the 9 and 10 combines the advantageous features of the third embodiment according to the 7 and 8th with the advantageous features of the second embodiment according to the 5 and 6 Furthermore, by referring to the 5 and 6 described engagement contour 66 is provided. In contrast to that with reference to the 5 and 6 described engagement contour 66 has the engagement contour 66 in the fourth embodiment according to the 9 and 10 however, elongated engagement recesses 68 on, each opposite a radial 56 . 58 in the circumferential direction 12 . 14 inclined and therefore to the corresponding inclined axial projections 42 . 44 are adjusted. These are the axial projection 42 associated engagement recesses 68 in the radial direction 8th outwards in the direction of the interruption 36 and thus in the circumferential direction 14 of the circlip 20 opposite the respective radials 56 inclined while the axial projection 44 associated elongated engagement recesses 68 in the radial direction 8th outwards in the circumferential direction 12 , thus in the direction of the interruption 36 of the circlip 20 , opposite the respective radials 58 are inclined.

Although the circlip 20 in the above-described embodiments, only in the axial direction 4 on the supporting component 16 can be supported or supported, it is understood that this supplementally in the axial direction 6 on the supporting component 16 can be designed supportable or supported, wherein for this purpose, for example, further in the radial direction 10 inwardly projecting and in the circumferential direction 12 . 14 spaced apart approaches can be provided, in the axial direction 6 from the prominent approaches 26 are spaced so that the circlip 20 also in the axial direction 6 on the supporting component 16 can be supported or supported. Also, instead of the multiple, in the circumferential direction 12 . 14 spaced projections protruding 26 also a groove in the supporting component 16 be provided, in which the retaining ring 20 would be arranged. In addition, it is possible to use a variety of circumferentially 12 . 14 spaced-apart protruding approaches 26 one in the circumferential direction 12 . 14 closed circumferential or continuous protruding approach 26 provided. In addition, it should be noted that the circlip 20 in the foregoing described embodiments as a radially inner locking ring 20 is trained. However, the preceding embodiments and advantages can be correspondingly also for a retaining ring 20 apply, as a radially outer circlip 20 on the supporting component 16 is arranged, optionally in an outer groove.
