Abstract

A cam roller for a pod joint, comprising an inner rolling path and an outer ring unit, wherein a rolling path for the rolling on a bell housing section is arranged on an outer side of the outer ring unit, a plurality of rolling elements, wherein the plurality of rolling elements are arranged between the inner rolling path and the outer ring unit, and a cage device, wherein the plurality of rolling elements are arranged within the cage device, wherein the cage device includes at least one separating point in circumferential direction.

Claims

1. A cam roller for a pod joint, comprising:

an inner rolling path;

an outer ring unit, wherein a rolling path configured to allow rolling on a bell housing section is arranged on an outer side of the outer ring unit;

a plurality of rolling elements, wherein the plurality of rolling elements are arranged between the inner rolling path and the outer ring unit;

a cage device, wherein the plurality of rolling elements are arranged within the cage device, wherein the cage device includes at least one separating point in circumferential direction.

2. The cam roller of claim 1, wherein the inner rolling path is formed at an inner ring unit configured to receive a pin of a shaft stub section.

3. The cam roller of claim 1, wherein the cage device features exactly one separating point.

4. The cam roller of claim 1, wherein the cage device is designed as a segment cage and/or features more than one separating point.

5. The cam roller of claim 4, wherein the cage device is designed as a window cage.

6. The cam roller of claim 3, wherein the cage device is designed as a center cage.

7. The cam roller of claim 6, wherein the outer ring unit comprises a circulating guiding groove for the plurality of rolling elements.

8. The cam roller of claim 7, wherein a securing side ring is arranged within the outer ring unit and secures the plurality of rolling elements in an axial direction.

9. The cam roller of claim 8, wherein the cam roller further includes an inner ring unit formed in a single piece and is configured to carry an outer rolling path for the plurality of rolling elements.

10. (canceled)

11. A cam roller for a pod joint, comprising:

an inner ring device configured to receive a pin of a shaft stub portion;

an outer ring device, wherein a running path for running on a bell housing portion is arranged on an outer side of the outer ring device;

a plurality of rolling bodies arranged between the inner ring device and the outer ring device; and

a cage device that includes rolling bodies and at least one separating point in a circumferential direction.

12. The cam roller of claim 11, wherein the inner ring device is formed as a single piece and is configured to carry an outer rolling path for the plurality of rolling bodies.

13. The cam roller of claim 11, wherein the outer ring device is formed as a single piece and is configured to carry an inner rolling path for the plurality of rolling bodies.

14. The cam roller of claim 11, wherein the cam roller includes at least one securing side configured arranged within the outer ring and configured to secure the rolling bodies in an axial direction.

15. The cam roller of claim 14, wherein the outer ring unit includes circulating ring grooves configured to allow the securing side ring to be placed in a form-fit manner.

16. The cam roller of claim 11, wherein the pod joint is a tripod joint.

17. The cam roller of claim 11, wherein the cage device includes a continuous connect link formed in an axial direction between respective rolling bodies.

18. The cam roller of claim 17, wherein the cage device includes a window that encloses one of the rolling bodies.
