Description

 Method for producing a joint and / or a chassis component with a

 joint

The invention relates to a method for producing a joint and / or a chassis component with a joint, which is associated with a longitudinal axis, the joint has at least one joint sleeve and at least one closure ring, in a closure ring assembly step, the closure ring is inserted into the joint sleeve, in a closure ring attachment step If the locking ring is fixed axially in the direction of the longitudinal axis of the joint, in a joint sleeve fastening step, the joint sleeve is fixed axially in the direction of the longitudinal axis of the joint on a counterpart, the counterpart having a sleeve receiving opening for inserting the joint sleeve. Furthermore, the invention relates to a joint, a sleeve joint and / or a chassis component with such a joint.

Such a method or joint is known from DE 10 2012 207 527 A1. Here, the joint is formed as a sleeve joint or ball sleeve joint and the joint sleeve as an outer sleeve. The locking ring is pressed into the outer sleeve. Here, the locking ring is seated in the axial direction at least form-fitting between an axial end of the outer sleeve, which is radially inwardly deformed, bent or rolled, and an inner sleeve. Thus, the forming of the axial ends of the outer sleeve can be done by rolling. These axial or free ends are also referred to as rolling edges or closing edges.

This has the disadvantage that due to the Verroll process of the axial end of the outer sleeve on the outside of the outer sleeve, a Materialaufwurf can arise. This material throw must usually be removed in a subsequent process or in a separate step in order to provide the most uniform possible, smooth or uneven surfaces of the outer sleeve. An uneven outer surface due to a material throw-off or multiple material drops would be disadvantageous, for example, for the installation of the joint and / or requirements for the joint in a chassis component. Here, the treatment of the ßenseite the outer sleeve to remove the material Aufwurfs done by grinding. This additional step causes an undesirable overhead.

It is the object underlying the invention to further develop a method and / or a joint of the type mentioned at the outset such that post-processing of the joint sleeve and / or an outer side of the joint can be dispensed with. In particular, an alternative embodiment is to be provided.

The object underlying the invention is achieved by a method according to claim 1 and by means of a joint, sleeve joint and / or chassis component with such a joint according to claim 10. Preferred developments of the invention can be found in the subclaims and in the following description.

Thus, a method for producing a joint and / or a chassis component is proposed with a joint, wherein the joint is associated with a longitudinal axis. In particular, the longitudinal axis extends in the axial direction of the joint and / or the longitudinal axis defines the axial direction of the joint. The joint has at least one joint sleeve and at least one locking ring. In a lock ring mounting step, the lock ring is inserted into the hinge sleeve. In one, in particular the closure ring assembly step subsequent closure ring attachment step, the closure ring is axially fixed positively in the direction of the longitudinal axis of the joint. Preferably, the closure ring is also radially in relation to the longitudinal axis of the joint, in particular form-fitting and / or due to the introduction of the closure ring in the joint sleeve, set. The closure ring can thus be fastened to the joint sleeve and / or with respect to the joint sleeve in the context of the closure ring fastening step. In a joint sleeve attachment step, the joint sleeve is fixed axially in the direction of the longitudinal axis of the joint on a counterpart. In particular, due to the joint sleeve attachment step, the joint is fixed to the counterpart. In particular, in the context of the present application, a definition of such an attachment is to be understood, so that a relative change in position of the two parts fixed to each other is prevented. The GE- genstück has a sleeve receiving opening for insertion of the joint sleeve. In particular, the sleeve receiving opening is formed as a passage opening.

In particular, a through-opening in the sense of the invention is to be understood to mean a round or non-round recess penetrating the counterpart or the respectively relevant component. Preferably, the passage opening is completely, in particular radially encircling the longitudinal axis, enclosed by the counterpart or the respectively relevant component.

The Verschlussbefestigungsschntt and the Gelenkhülsenbefestigungsschntt done simultaneously in a common forming step. In this case, a free end of the joint sleeve is reshaped such that the deformed free end engages over both the closure ring and the counterpart transversely to the longitudinal axis of the joint. In particular, an overlap is to be understood as a partial overlaying or interlocking. Preferably, the spreading takes place at right angles to the axial direction of the longitudinal axis of the joint.

It is advantageous that the Verschlussbefestigungsschntt and the Gelenkhülsenbefestigungsschntt are summarized. In particular, only the free end of the joint sleeve is formed in the forming step. In this case, the formation of a material throw-up, as known from the prior art, can be avoided. Accordingly, a subsequent treatment process for processing, in particular for grinding, the outside of the joint sleeve and / or the joint can be dispensed with. Thus, a significant simplification of the manufacturing process can be achieved.

The longitudinal axis of the joint preferably forms a longitudinal central axis of the joint and / or the joint sleeve. One or any direction transverse to the longitudinal axis direction is referred to in particular as a radial direction. Preferably, the joint has a hinge axis about which the joint and / or an inner joint part is movable. Preferably, the hinge axis and / or the longitudinal axis extends in the axial direction of the joint sleeve. The joint axis and the longitudinal axis can be sammenfallen. In particular, the hinge axis extends in the axial direction of the joint and / or in the axial direction of the longitudinal axis.

Preferably, the free end of the joint sleeve in the forming step, in particular to a mushroom-shaped in cross-section, roll edge contour is formed. The outer diameter of the free end may correspond to the maximum outer diameter of the joint sleeve. The joint sleeve may be provided with an outside diameter slightly larger than an inside diameter of the sleeve receiving opening of the counterpart such that in the joint sleeve mounting step, the joint sleeve is inserted into the sleeve receiving opening by pressing the joint sleeve into the sleeve receiving opening. Thus, the joint sleeve can be additionally fixed non-positively on the counterpart.

In particular, the free end after a Gelenkhülsenmontagageschntt, in which the counterpart is inserted into the sleeve receiving opening extends in the axial direction of the longitudinal axis beyond the counterpart. In particular, the joint sleeve assembly does not occur before the lock ring mounting step.

According to one embodiment, the joint sleeve is determined due to the forming step at least form-fitting manner to the counterpart. This can be due to the positive fixing of the joint sleeve on the counterpart movement of the joint sleeve with respect to the counterpart in the direction of the longitudinal axis and / or be blocked transversely to the longitudinal axis of the joint. Preferably, due to the conversion Formschrittes both the locking ring and the counterpart form-fitting and frictionally fixed to the joint sleeve and / or clamped.

In particular, in the forming step, the free end and a forming tool are pressed axially against each other, so that the free end of the joint sleeve is formed. Here, the forming can be carried out in the forming step by means of a single forming tool.

The sleeve receiving opening 42 is formed due to the sleeve-like or hollow cylinder-like design of the counterpart 7. To insert the joint sleeve 6 in the counterpart 7, the counterpart or the outer sleeve 7 is pushed over the joint sleeve or inner sleeve 6. Alternatively, the inner sleeve 6 can be introduced into the outer sleeve 7. In this embodiment, the joint sleeve or inner sleeve 6 has a circumferential groove groove 34 on its outer side. The sleeve groove is axially bounded on both sides by means of the radially projecting free ends 14, 15. Thus, the free ends 14, 15 project radially with respect to the sleeve groove 34.

After the joint sleeve mounting step is the Lock ring 12 is introduced into the joint sleeve or inner sleeve 6 in a closure ring mounting step. The contact surfaces 17, 18 are ring-like or annular. The locking ring 12 has in the region of the annular portion 16 its maximum outer diameter. The maximum outer diameter of the closure ring 12 and the inner diameter of the joint sleeve or inner sleeve 6 in the region of the free end 14 are designed or matched such that the closure ring 12 is inserted or pressed into the inner sleeve 6 in the region of the free end 14 in the context of the lock ring assembly step , The locking ring 12 is inserted in the axial direction of the longitudinal axis 2 in the inner sleeve 6 until the annular portion 16 bears against the contact surface 17.

After the lock ring mounting step, a lock ring attaching step is performed. As part of the locking ring attachment step, the locking ring 12 is fixed in a form-fitting manner axially in the direction of the longitudinal axis 2 of the joint 1. Furthermore, a joint sleeve fastening step takes place in which the joint sleeve or inner sleeve 6 is fixed in a form-fitting manner axially in the direction of the longitudinal axis of the joint 1 on the counterpart or outer sleeve 7.

In this embodiment, the lock ring attaching step and the joint sleeve attaching step occur simultaneously in a common forming step. Here, the free end 14 of the joint sleeve or inner sleeve 6 is reshaped such that the deformed free end 14 of the joint sleeve or inner sleeve 6 both the locking ring 12 and the counterpart or the outer sleeve 7 transversely, namely at right angles, to the longitudinal axis 2 of Joint 1 overlaps.

The deformed free end 14 forms a rolling edge contour and is substantially mushroom-shaped in cross-section. The deformed free end 14 extends over the annular section 16 of the locking ring 12 radially inwardly directed. At the same time, the deformed free end 14 radially overlaps the edge 19 of the locking ring 12. Thus, the locking ring 12 and the annular portion 16 is positively fixed between the deformed free end 14 and the contact surface 17 of the joint sleeve or inner sleeve 6.

To carry out the forming step, the free end 14 and the forming tool 36 are pressed axially against each other, so that the free end 14 is formed to its apparent from Figure 5 state. For this purpose, the forming tool

36 comprise a roller assembly having a plurality of rollers 37 arranged around a forming tool axis of rotation. Here, the Umformwerkzeugdrehachse coincides with the longitudinal axis 2. For the forming of the free end 14, the rollers

When the inner joint part assembly step, the bearing shell 8 and the inner joint part 9, in particular the bearing shell 8 together with the inner joint part 9, in the Gelenkhülseninnenraum 32 of the joint sleeve or inner sleeve 6 is used. For this purpose, the bearing shell 8 and the inner joint part 9 is inserted through a mounting opening 38 of the joint sleeve or inner sleeve 6 in the Gelenkhülseninnenraum 32. The mounting opening 38 is arranged in an axially remote from the locking ring 12 area.

This is followed by a further closure ring assembly step, in which the closure ring 13 is inserted into the joint sleeve or inner sleeve 6. Subsequently, a further closure ring fastening step takes place, in which the closure ring 13 is fixed in a form-fitting manner axially in the direction of the longitudinal axis 2 of the joint 1. There is also a further joint sleeve fastening step, in which the joint sleeve or inner sleeve 6 is fixed in a form-fitting manner axially in the direction of the longitudinal axis 2 of the joint 1 on the counterpart or the outer sleeve 7. The further closure ring assembly step, the further closure ring attachment step and the further joint sleeve attachment step are carried out analogously to the corresponding In this regard, reference is also made to the preceding description of the above-described locking ring 12 in Figures 4 and 5.

Thus, the further closure fastening step and the further joint sleeve fastening step occur simultaneously in a common further forming step. Here, the free end 15 of the joint sleeve or inner sleeve 6 is reshaped such that the deformed free end 15 according to Figure 1, both the locking ring 13 and the counterpart or the inner sleeve 6 transversely, namely in this embodiment, at right angles to the longitudinal axis 2 of the joint 1 overlaps.

Subsequently, the sealing bellows 23, 24 are mounted by means of the clamping rings 26, 31, so that the joint 1 is completely assembled according to FIG.

FIG. 7 shows a perspective side view of a chassis component 39 with a further joint 40 according to the invention. In this exemplary embodiment, the chassis component is designed as a handlebar. The joint 40 is arranged in the chassis component 39. In this case, the chassis component has a structural part 41 and the joint 40 is arranged in the structural part 41.

In this embodiment, the hinge 40 is formed as a sleeve joint, namely as a ball and socket joint. The structure of the joint 40 and the connection of the joint 40 with the chassis component 39 will be explained in more detail with reference to the following figure.

FIG. 8 shows a sectional side view of the further joint 40 according to FIG. 7, wherein the further joint 40 is mounted in the chassis component 39. The joint 40 is constructed similar to the joint 1 according to FIG. In that regard, reference is also made to the preceding description. In contrast to the joint 1 according to FIG. 1, however, the joint 40 according to FIG. 8 has no counterpart in the embodiment as an outer sleeve 7. Instead, the chassis component 39 itself is used as a counterpart. Specifically, in this case, the structural part 41 serves as a counterpart to the interaction with the joint sleeve 6. The production of the joint 40 likewise takes place analogously to the production of the joint 1 according to FIGS. 1 to 6. Here, according to Figures 7 and 8, instead of the outer sleeve 7, the structural part 41 is used as a counterpart. Thus, the joint 40 in a passage opening of the chassis component 39 and the structural part 41 can be produced.
