Description

The invention relates to a tripod roller for a constant velocity joint with a positive securing portion having the features of the preamble of claim 1, a constant velocity joint with at least one of these tripod rollers and a method for mounting the tripod roller.

Constant velocity joints are joints for uniform angular velocity and torque transmission from a shaft to an angularly mounted further shaft. For example, constant velocity joints are used to transmit drive torque from an engine to the wheels of a steered axle of a vehicle.

One type of constant velocity joints are tripod joints, which often have a tripod star with pins as a joint partner, wherein the pins are aligned in the radial direction to the joint partner and each carry a tripod roll. The tripod star with the tripod rollers engages in a joint bell as a second joint partner, which has three in the axial direction to the second joint partner extending, elongated recesses into which the three tripod rollers can move axially to the second joint partner.

An example of such a constant velocity joint is in the published patent application DE 44 39 965 A1 shown, which is probably the closest prior art. The publication discloses a tripod unit in which a positive coupling directly between an outer ring and a tripod roller and an inner ring of the tripod roller and the inner ring has an annular shoulder which rests on the front side of the outer ring of the tripod roller.

It is an object of the invention to provide an inexpensive to be manufactured tripod roller, a corresponding constant velocity joint with the tripod roller and a method for mounting the tripod roller. This object is achieved by a tripod roller with the features of claim 1, a constant velocity joint having the features of claim 9 and by a method having the features of claim 10. Preferred or advantageous embodiment of the invention will become apparent from the dependent claims, the following description and the accompanying drawings.

The invention relates to a tripod roller for a constant velocity joint. The constant velocity joint is designed in particular as a synchronized Verschegelegelenk. In particular, the constant velocity joint is designed as a homokinetic joint for uniform angular velocity and torque transmission from a shaft to a second shaft, preferably angled thereto. Particularly preferably, the constant velocity joint is formed as a transmission joint for transmitting a driving torque from a motor to steered wheels of a vehicle. In particular, the constant velocity joint between an axle and a drive shaft is arranged. The constant velocity joint has, as a first joint partner, a tripod star with three pins extending in the radial direction to an axis of the tripod star. On the pin a tripod roller is placed in each case. The tripod star engages in a joint bell as a second joint partner, wherein the joint bell has three in the axial direction to the second joint partner extending, elongated recesses into which the three tripod rollers can move axially to the second joint partner.

The tripod roller has an inner ring for placement on the tripod star, in particular on one of the pins of the tripod star. Further, the tripod roller has an outer ring, wherein the outer ring is arranged coaxially with the inner ring. Hereinafter, inner ring and outer ring are collectively referred to as rings. The rings are also arranged coaxially to a tripod roller axle, which is defined by the pin of the tripod star. Preferably, the outer ring has a spherical and / or spherical segment-like outer side in a longitudinal section along the tripod roller axis.

The tripod roller has a plurality of rollers, in particular cylindrical rollers, in particular needles, wherein the rollers are arranged to roll between the rings. In particular, the rollers are rectified and / or oriented parallel to the tripod roller axle. Particularly preferably, the rollers are arranged in a single row.

On a first axial side of the tripod roller, a first positive locking is arranged relative to each other for positive locking of the rings, which acts in a first axial direction. Particularly preferably, the first form-fit for positively securing the rings to each other in exactly a first axial direction is formed, wherein the second axial direction is released. It is envisaged that the first positive connection can be formed and / or formed via direct contact of the rings with one another. Thus, the positive connection is formed by integral and / or integrally molded portions of the rings. In particular, no further components, such as retaining rings or the like, are provided for forming the first positive connection. The positive connection occurs in particular when the rings are to be opened to each other in the first axial direction. Thus, it may be provided in a normal operating state that the rings are arranged without contact with each other and only at an attempted separation in the first axial Contact directly direction and form the first form fit.

In the context of the invention, it is proposed that a second positive connection is arranged on a second axial side of the tripod roller, in particular on the other side of the tripod roller. The second positive connection is for positive securing of the rings to each other in a second axial direction, which is directed against the first axial direction formed. Again, it is provided that for the formation of the second positive connection, a direct contact of the rings is formed and / or formed to each other. In particular, the second positive connection is formed exclusively via integral and / or integrally molded regions of the rings. In particular, no additional components, such as circlips, are necessary. The positive connection occurs in particular when the rings are to be opened to each other in the second axial direction. Thus, it can be provided in a normal operating state that the rings are arranged without contact with each other and contact only at an attempted separation in the second axial direction directly and form the second positive connection.

It is a consideration of the invention to transfer the positive securing of additional components in structures of the rings in order to produce the Tripodenrolle cheaper in this way. It is particularly advantageous if the form-fitting are distributed on two axial sides, wherein it is preferably provided that the rollers between the two axial sides are arranged to keep the complexity of the contour changes for the form-fitting on each side as small as possible. Due to the saving of additional components and the low complexity of the structural design of the positive fit due to the distribution on the two axial sides of the tripod roller tripod roller can be made in the entirety particularly cost.

In a preferred embodiment of the invention, the first positive locking and / or the second positive locking is optionally formed in each case by two positive locking partners. One of the rings, thus either the inner ring or the outer ring, has a shoulder side as form-fitting partner. The shoulder side has a shelf with a contact surface for the rolling elements. The board is integral and / or integrally formed with the ring. By contrast, the other ring has a raceway side as form-locking partner. The raceway side is board-free. Preferably, the raceway side opposite the raceway of the ring with the raceway side in the same radial height or radially set back relative to the raceway, so that a roller can be inserted over the raceway side in the axial direction. Thus, the raceway side in the inner ring to be radially inward and the outer ring to be reset radially outward.

It is envisaged that one of the form-fitting partners, preferably exactly one of the form-fitting partners, has a securing region, wherein the securing region secures the other form-fitting partner in a form-fitting manner in the axial direction. For the first and / or second form-fit, respectively one shoulder side and one raceway side act on the same axial side. It is preferred that the securing area forms an axial end limit for the form-locking partner. Thus, the securing area prevents the form-locking partner and thus the other ring, can be moved out in the axial direction against the securing area.

Functionally considered, the securing region is thus arranged such that it secures the other ring in a form-fitting manner in the axial direction. Thus, the securing area is structurally designed so that an axial displacement of the other ring is prevented by the securing area, in particular in a form-fitting manner. In particular, the securing area is realized as a region of the ring formed in the radial direction to the tripod roller axis as a disturbing contour for the other ring. In particular, the securing region is formed as an integral part of the ring and / or in one piece and / or in one piece and / or integrally with the ring.

The securing area is preferably designed as a stamping area and / or caulking area. In particular, the securing area is realized as a forming area, wherein the final shape of the securing area is produced by forming.

In a preferred embodiment of the invention, the securing area is generated by a forming tool with a direction of action in the axial direction against the ring. Such a forming of the ring ensures that the material flows in an axial end region of the ring in the radial direction and thereby forms the securing region. In particular, the ring is supported against the forming only in the axial direction. It is a further consideration of the invention that the security area is not formed by a preceding separation process step, such as milling, etc., or by a previous forming step with greater material flow, but is implemented only by embossing and / or caulking. Thus, in comparison to a separating process, a laborious step is saved and compared to the forming process, the degree of deformation is significantly reduced, so resulting from a forming step with a higher degree of deformation Problems can not occur. It is thus possible, for example, for the securing area to be hardened or for the shape of the ring with the securing area to be changed so little by embossing and / or caulking that it is possible to dispense with shaping reworking in the region of the raceway of the ring. Thus, the tripod roller can be made cheaper by the preferred embodiment.

In an alternative embodiment of the invention can also be provided that the form-fitting partners of the first positive connection are formed by a separating process and at least one of the form-fitting partner of the second positive connection by embossing and / or caulking. This embodiment is based on the consideration that the first form-fit can be formed as desired, for example, characterized in that the form-fitting partners are produced by separating. However, the second positive connection is formed by embossing and / or caulking. Thus, it is possible to pre-assemble the tripod roller, in particular to position the rollers between the rings and to make the Tripodenrolle to a self-holding assembly after this pre-assembled state by the second positive connection is produced by embossing and / or caulking. Thus, it is possible to close the Tripodenrolle by the caulking and / or embossing in the assembly of Tripodenrolle.

In a possible structural realization of the invention, the securing area is formed as a continuous and / or continuous area around the tripod roller axle. This embodiment has the advantage that a rotational symmetry is maintained in the securing area and this is thereby made more stable.

In an alternative embodiment of the invention, the securing area is designed as a plurality of partial areas which surround the tripod roller axis but are interrupted. For example, it may be sufficient that only a limited number of partial regions, such as less than five partial regions, in particular fewer than four partial regions and especially precisely three partial regions, such embossing and / or caulking is implemented in order to form the securing region. In this embodiment, the securing area in the locking ring can be produced particularly cost-effectively, since the force required for forming and the resulting load on the securing ring is comparatively small.

In a first possible embodiment of the invention, the ring is hardened in sections. For example, the raceway for the rollers is hardened. However, it is envisaged that the securing area is uncured. In this embodiment, it is particularly easy to reshape the ring to produce the security area by means of embossing and / or caulking.

However, it has proven to be advantageous that the production of the security area by embossing and / or caulking is also possible, although the security area is hardened. Thus, it is particularly preferred that the ring is completely cured with the securing area and is, for example, through-hardened. This configuration makes it possible to inexpensively produce a hardened ring with the securing area. In particular, the securing area is introduced into the hardened ring.

In an alternative embodiment of the invention, one of the form fit as a form-locking partner on two shoulder sides, wherein the shoulder sides each have a shelf, wherein the rims are arranged at the same axial height and wherein one of the shoulder sides carries the securing area. This embodiment has the advantage that the roller can optionally start on the shoulder region, in particular on the one ring, or on the shoulder region, in particular on the other ring. As a result, the rings are positioned independently of each other in the axial direction. The positive connection can be effected in that one of the shoulder sides, in particular one of the shelves carries the securing area.

Optionally, it can be provided that the ring without the securing area has a throat area, the throat area facing the securing area of the other ring. In particular, the throat area is formed circumferentially. For example, the throats region is introduced by reshaping or separating. It is particularly preferred that the throat region is arranged overlapping with the securing region, in particular in the radial direction. The throat area is designed as a franking or omission. By the throat area is implemented that makes the ring with the throat area a diameter jump, so that the positive locking when moving the rings relative to each other also intermittently engages and does not lead to a clamping. In particular, can be reduced by the throat area, the axial width of the ring with the throat area.

Another object of the invention relates to a constant velocity joint, wherein the constant velocity joint at least one tripod roller, as has been previously described, or according to one of the preceding claims.

Another object of the invention relates to a method for mounting the Tripod roller, wherein in a first step, the rollers between the rings are arranged and closed in a second step of the form-fitting or both form-fitting by forming at least one ring. Preferably, in the second step, the at least one ring is caulked and / or embossed to provide the securing area. Thus, a simple mounting of the tripod roller is possible, wherein a captive and / or the transition to a self-holding assembly is implemented in the partially assembled or fully assembled state.
