B. to improve during load change operations. For example, the DE 41 30 183 A1 a tripod joint, in which by special design of the raceways in the Laufbahnausnehmungen and the outer rings of the bearings tilting of the rolling bearing outer ring in the Laufbahnausnehmung z. B. to be prevented at a load application or a load change. This is to ensure that the outer ring comes to rest only on a raceway of the raceway recess, so that the outer ring can roll in the Laufbahnausnehmung friction.

Also from the EP 1 253 337 A1 is a homokinetic joint with reduced rotational clearance known. Both the raceways of the Laufbahnausnehmungen and the surface of the rolling bearing outer ring are designed spherical. Furthermore, the rolling bearing outer ring is divided into two parts.

Both Tripod steering is a relative one complex design of the bearings together, which Cost disadvantages brings with it.

task The present invention is therefore a tripod joint with advantageous Indicate running characteristics, in particular with minimum rotational play, which has a simplified structure. Furthermore, a should A method for producing a favorable Tripodegelenks indicated become.

Solved This object is achieved by a tripod joint with the characteristics of Claim 1 and a method having the features of the claim 14th

One Tripod joint according to the invention is for the Drive train of a motor vehicle provided. In particular it for use as an inner joint of a drive shaft a front-wheel drive motor vehicle suitable. It includes one Tripod esters, which forms a plurality of cones. Everyone who Spigot carries a rolling bearing. The tripod joint further comprises an outer joint, which a plurality by itself in the axial direction (ie in the direction of rotation D of the outer joint the tripod joint) extending Laufbahnausnehmungen. In each Laufbahnausnehmung is a worn by a pin Rolling bearings slidably mounted in the axial direction. Farther are in each career recess two opposite each other arranged raceways for mechanical contact with formed therein rolling bearing. at a load transfer into the outer joint is this over the bearings and these bearing pin transferred to the Tripodestern.

According to the invention now the rolling bearings each have an outer ring, in the outer peripheral surface at least one, preferably but two circumferential annular grooves are formed. The ring is advantageous formed in one piece, but can also be multi-part, especially in two parts be educated. Furthermore, in the raceways of the outer joint, at least a rail-like guide element is formed, preferably but two guide elements in the outer ring trained annular groove / s intervene. According to the invention at least one of these rail-like guide elements as a separate component and not in one piece with the outer joint educated.

Here, a rail-like guide element is to be understood as a structure which extends in the direction of the axis of rotation D of the outer joint and rises from a track. It may be z. B. elevate substantially in the circumferential direction of the outer joint of the career. Furthermore, the rail-like guide element should form at least one guide surface on which the outside can roll ring of a rolling bearing. However, the rail-like guide element preferably forms two guide surfaces, which are arranged on sides of the guide element facing away from one another. In a particularly preferred embodiment, the separate rail-like guide element forms three guide surfaces.

The separate training of the rail-like guide element offers the advantageous possibility of the guide element from another material and by another method to manufacture as the outer joint of the tripod joint. For example For example, the rail-like guide element can be extruded Tool steel or a hardened round steel exist. The outer joint is typically cast or forged Stole. In this case, the separately formed rail-like guide element advantageous at least one point mechanically on the outer joint fixed, but preferably at several points. The mechanical Connection between the rail-like guide element and the outer joint can, for example, by welding (eg spot welding), caulking, soldering, gluing or other suitable joining methods known in the art respectively.

The Ring groove in the outer ring of the bearing and the separate rail-like guide element in the raceways are preferably designed so that during a power transmission from the outer joint on the Tripodestern the outer ring the bearings each on the / the separate rail-like Guide element (s) - in particular the one of unrolls this trained guide surfaces. This is to ensure that a mechanical Contact between roller bearing outer ring and raceway recess at a load transfer over the invention Tripod joint essentially forms only in the region of a career. A mechanical contact of the rolling bearing outer ring in the area of the second, oppositely arranged track should, however, by the special shape of the outer ring - outer peripheral surfaces and the separately formed rail-like guide elements be avoided as far as possible. Hereby leave particularly advantageous rolling properties of rolling bearings in the raceway recesses and thus particularly good synchronization properties realize the Tripodegelenkes invention.

In a particularly preferred embodiment form during unrolling a rolling bearing at a load introduction into the inventive Tripod joint on a track at least two, but preferably three or more point contacts between the outer peripheral surface the outer rings of rolling bearings and raceways, d. H. the rail-like guide elements, in the outer joints out.

In a further advantageous embodiment, the separately formed rail-like guide element at least in sections a circular arc-shaped cross section. Furthermore includes the associated annular groove, in which the aforementioned rail-like Guide element with at least partially circular arc-shaped Cross section engages, also at least in sections one circular arc-shaped cross-section. It is preferred the radius of curvature of the circular arc section the rail-like guide element smaller than the one the associated annular groove in the outer ring of the rolling bearing. In this embodiment, in particular, the Hertzian contact voltages minimized.

alternative it is also possible that the one annular groove in the outer peripheral surface the rolling bearing outer ring, in which the aforementioned rail-like guide element engages, at least in sections has a gothic cross section. By this one understands two mutually inclined spherical surface sections, the one Include angle α with each other. The combination from annular groove with at least partially Gothic cross-section and rail-like guide element with at least sections circular arc cross-section ensures that always two defined point contacts P between rail-like guide element and form a ring groove.

Basically, the Tripodegelenk each known from the prior art suitable shaping with respect. The pins of the tripod star or the inner rings of the rolling bearing have. In a particularly preferred embodiment, the pins of the tripod star are formed spherical, which is to be understood in that the pins are at least partially form spherical surfaces. The complementary surfaces in the inner ring of the rolling bearing can be configured, for example, cylindrical, so that the rolling bearing has an inner ring with a cylindrical inner recess. Alternatively, it is also possible to provide the inner rings of the rolling bearing with an inner recess, the shape of which in turn is formed at least partially spherical surface. In both embodiments, the inner rings can perform a tilting movement on the pin of the Tripodesterns. In the latter embodiment, it is of particular advantage if the inner ring and the outer ring of the rolling bearing in the direction of the axis of rotation of the bearing are mutually displaceable. Such a degree of freedom of movement, however, is not required if the inner ring of the rolling bearing has a cylindrical inner recess, since here the spherical pin of the tripod star in the inner recess of the rolling bearing inner ring back and forth can slide.

1 shows a schematic representation of a first embodiment of a tripod joint according to the invention 1 in perspective view. The outer joint 20 has a rotation axis D and is open on one side. At its closed end opens the outer joint 20 in a wave shaft 28 for example, to an output shaft of a transmission of the motor vehicle. In the outer joint 20 are three career recesses 22 formed, which extend in the direction of the axis of rotation D. Each raceway recess 22 forms two opposing tracks 24 out on which in the Laufausausnehrung 22 used rolling bearings 60 Roll off, of which in 1 for the sake of clarity, only one is shown. Here is the dimensioning of the bearings 60 chosen so that when an introduction of force, for example, in the outer joint 20 of the tripod joint 1 the rolling bearing 60 with its outer ring 64 actually only on a career 24 the raceway recess 22 rolls.

How out 1 is further apparent, is each Laufbahnausnehmung 22 in the outer joint 20 a cone 42 in the outer joint 20 used tripod esters 40 assigned. The pins carry 42 each a rolling bearing 60 , The tripod esters 40 has an inner recess in the inner wall a variety of splines 44 are formed for connecting a connecting shaft, for example, a ball displacement joint.

Preference is given to outer joint 20 and wave shaft 28 integrally formed as a forged part, wherein in the Laufbahnausnehmungen 22 trained careers 24 after forging the outer joint 20 further processing steps for finishing and curing are subjected.

2 shows the first embodiment of a tripod joint according to the invention 1 according to 1 again in a partially sectioned view, from which the structure of the rolling bearing 60 , in particular of its outer ring 64 , as well as the shaping of the career 24 the raceway recess 22 in the outer joint 20 become apparent. The ones from the cones 42 of the Tripodester 40 worn rolling bearings 60 have an inner ring 62 and one outer ring 64 on, between which a variety of cylindrical rollers 68 is arranged. Here are inner ring 62 and outer ring 64 in the direction of the axis of rotation R of the rolling bearing 60 movable against each other. As can be seen from the sectional view of the rolling bearing 60 in 2 gives, is the outer ring 64 of the rolling bearing 60 with a circumferential annular groove 66 Mistake. In this engages a separately designed rail-like guide element 26 one, each one in the career 24 the raceway recess 22 trained receiving recess 25 used and preferably mechanically fixed there. In this case, this rail-like guide element 26 be formed separate component in the form of an insert, ie separately from the outer joint 20 ,

How out 2 also can be seen, the pins 42 of the Tripodester 40 spherical surface sections 43 on. At the same time, the inner recess of the inner ring 62 partially spherical, so that of the pin 42 worn inner ring 62 of the rolling bearing 60 and thus this overall a tilting movement about the pin 42 can perform.

In the first embodiment according to the 1 to 4 is in the careers 24 the raceway recess 22 in the outer joint 20 only one rail-like guide element 26 trained, as in detail again 3 is apparent. At the same time is in the outer ring 64 the rolling bearing 60 only a circumferential annular groove 66 formed, in which the rail-like guide element 26 intervenes. Due to the special shape of the raceway 24 and the outer peripheral surface of the outer ring 64 of the rolling bearing 60 arise when rolling the rolling bearing 60 on the track 24 mech. Contacts only between the outer ring 64 and the career 24 , These are in 3 marked with P. All three contact points P are on the separately formed rail-like guide element 26 and have the same distance from the axis of rotation R of the rolling bearing 60 on, leaving a pure rolling motion of the rolling bearing 60 on the track 24 is possible. A partial sliding movement of the outer ring 64 showing the running properties of the tripod joint according to the invention 1 could negatively influence this is avoided. The in the first embodiment of the tripod joint according to the invention 1 realized three contact points P of the rolling bearing outer ring 64 with the career 24 also provide for a position stabilization of the rolling bearing outer ring 64 in the career 24 z. B. at a load introduction into the tripod joint according to the invention 1 , ie a tilting of the axis of rotation R of the rolling bearing 60 is thereby avoided. In this way it can be ensured that even with a load introduction into the tripod joint 1 a mechanical contact between the rolling bearing 60 and a raceway recess 22 only in the area of a career 24 takes place. A sliding application of the rolling bearing outer ring 66 on the opposite track 24 This can be safely avoided. The sliding movement of the outer ring of the rolling bearing, which is known from many prior art tripod joints, occurs on the track facing away from the force path 24 therefore omitted in this construction.

3 can continue the special shape of the bearing 60 and the pin 42 of the Tripodester 40 be removed. In particular, the spherical surface portion 43 of the pin 42 of the Tripodester 40 to recognize. With this corresponds the spherical inner recess 63 in the inner ring 62 of the rolling bearing 60 , so that a total of a tilting movement of the axis of rotation of the bearing 60 on the cones 42 becomes possible. The outer circumference of the rolling bearing inner ring 62 and the inner circumference of the rolling bearing outer ring 64 are each designed as a cylindrical surface, so that between the inner ring 62 and outer ring 64 cylindrical rollers 68 can roll off. Thereby the roles become 68 in the direction of the axis of rotation R of the rolling bearing 60 in the inner ring 62 fixed in their position. On the other hand, the position of the outer ring 64 on the rollers 68 essentially only by a securing projection 65 limited, the at the inner end of the rolling bearing outer ring 64 is trained. As a result, the rolling bearing outer ring 64 in the direction of the axis of rotation R of the rolling bearing 60 against the inner ring 62 displaced. The security advantage 65 limits the displacement movement of the outer ring 64 on the inner ring 62 and thus prevents falling apart of the pin 42 worn rolling bearing 60 for example, in the final assembly of the tripod joint according to the invention 1 ,

4 shows again the structure of the outer joint 20 , the tripod star 40 and the rolling bearing 60 of the tripod joint according to the invention 1 according to the first embodiment in a perspective view.

5 now shows the outer joint 20 A second embodiment of a tripod joint according to the invention 1 also in a perspective view, which was omitted for reasons of clarity, the tripod esters 40 to present again in detail. In this embodiment corresponds to the structure of the tripod star 40 and the rolling bearing 60 essentially the one according to the first embodiment. The second embodiment differs from the first embodiment substantially in that on the outer peripheral surface of the rolling bearing outer ring 64 two circumferential grooves 66 are formed. At the same time is on the career path 24 in the track recesses 22 of the outer joint 20 a separately trained rails like guide element 26 formed, which forms four guide surfaces and in the two circumferential annular grooves 66 in the rolling bearing outer ring 64 intervenes. This becomes clear again from the cut-out enlargement according to 6 from which the rail-like guide elements 26 in the career 24 the raceway recess 22 of the outer joint 20 can be seen. Also, the complementary circumferential annular grooves 66 in the outer ring 64 of the rolling bearing 60 seen.

In all embodiments, the separately formed rail-like guide elements in complementary, in the direction of rotation D of the outer joint 20 extending receiving recesses 25 in the career 24 inserted and mechanically fixed there, for example by means of one or more welds. Im in the 5 and 6 illustrated second embodiment are two rail-like guide elements 26 each career 24 provided, which may for example consist of hardened round steel.

In the enlarged representations of the 6 and 7 have the rail-like guide elements 26 each partially a circular arc-shaped cross-section. Likewise, the point in the rolling bearing outer ring 64 trained circumferential annular grooves 66 in sections, a circular arc-shaped cross-section. In this case, the radius of curvature of the circular arc-shaped portion of the rail-like guide element 26 at most the same size as the radius of curvature of the circumferential annular groove 66 in the rolling bearing outer ring 64 but preferably smaller than its radius of curvature. The latter version is in 7 as an enlarged view of the second embodiment according to the 5 and 6 shown. This results in a minimized Hertzian contact voltage at the contact points P between the rail-like guide element 26 and the ring groove 66 , In the embodiments according to the 5 to 7 Form in the area of each circumferential ring groove 66 two contact points P with one in the annular groove 66 engaging rail-like guide element 26 out, leaving a total of between the rolling bearing outer ring 64 and the career 24 of the outer joint 20 four contact points P occur. In this case, these contact points P are preferably again on a straight line which is parallel to the axis of rotation R of the rolling bearing 60 is oriented. In the four contact points P are provided, a further stabilization of the rolling bearing outer ring 64 against tilting, for example when a force is introduced into the tripod joint 1 , prevents, so that a pure rolling movement of the rolling bearing outer ring 64 on a career 24 a raceway recess 22 is ensured. This in turn leads to particularly advantageous running properties of the tripod joint according to the invention 1 ,

In an alternative embodiment, which in 8th is shown, corresponds to the structure of the tripod joint 1 essentially from the 5 . 6 and 7 apparent. Here, too, have the rail-like guide elements designed as separate components 26 in sections, a circular arc-shaped cross-section. On the other hand, those in the outer ring 64 of the rolling bearing 60 trained circumferential annular grooves 66 no sectionally circular arc-shaped cross-section, but here a Gothic shape is chosen for the annular grooves. As already explained, two mutually inclined spherical surface sections are to be understood here, which enclose an angle α with one another which is between 45 ° and 170 °, preferably between 90 ° and 150 °.
