Abstract

A driver module for clutches, in particular wet-running double clutch assemblies, including a clutch housing and a cover which are connected with each other, enclosing an interior space. The cover is rotationally fixed in relation to the clutch housing in the axial direction and in the circumferential direction by a connecting ring.

Claims (30)

1. A driver module for clutch assemblies comprising:

a clutch housing; and

a cover, the clutch housing and the cover being connected with each other, enclosing an interior space for receiving the clutch assembly, wherein the cover is secured on the clutch housing by a connecting ring, the connecting ring including elastic elements pretensioning the connection between the cover and clutch housing in the circumferential direction.

2. The driver module as recited in claim 1 wherein the clutch assembly is a wet-running double clutch assembly.

3. The driver module as recited in claim 1 wherein the cover is secured on the clutch housing by the connecting ring in the axial direction and in the circumferential direction.

4. The driver module as recited in claim 1 wherein the connection between the cover and the clutch housing by the connecting ring is rotationally fixed and free of play in the axial direction and/or circumferential direction.

5. The driver module as recited in claim 4 wherein the elastic elements are formed by the snap connection.

6. The driver module as recited in claim 1 wherein the cover and the clutch housing can be twisted relative to each other in the circumferential direction by a limited amount.

7. The driver module as recited in claim 1 further comprising between the cover and the clutch housing a first and second means, the first means providing a positive connection in the axial direction with free play, and the second means providing a stop in the circumferential direction.

8. The driver module as recited in claim 7 wherein the connecting ring is connected with the cover in a rotationally fixed connection in the circumferential direction by a snap connection, the cover being braced against the clutch housing in the axial direction by the positive connection.

9. The driver module as recited in claim 8 wherein the positive connection between the cover and the clutch housing in the axial direction is formed by a bayonet connection.

10. The driver module as recited in claim 1 further comprising between the cover and the clutch housing, means providing a positive connection in the circumferential direction.

11. The driver module as recited in claim 10 wherein the connecting ring is connected with the cover in a rotationally fixed connection in the circumferential direction by a snap connection, the cover being braced against the clutch housing in the axial direction by the positive connection.

12. The driver module as recited in claim 11 wherein the positive connection between the cover and the clutch housing in the axial direction is formed by a bayonet connection.

13. The driver module as recited in claim 11 wherein the connecting ring has a snap connection interacting with a complementary slot in the cover.

14. A driver module for clutch assemblies comprising:

a clutch housing;

a cover, the clutch housing and the cover being connected with each other, enclosing an interior space for receiving the clutch assembly, wherein the cover is secured on the clutch housing by a connecting ring; and elastic elements pretensioning the connection between the cover and clutch housing in the circumferential direction; and

a first means and a second means between the cover and the clutch housing, the first means providing a positive connection in the axial direction with free play, and the second means providing a stop in the circumferential direction wherein the clutch housing has a first and a second driver element, the first and second driver elements being arranged at uniform intervals from each other in the circumferential direction in an outer circumference, the first and second driver elements having different end regions that interact with complementary cutouts in the cover extending in the circumferential direction, the cutouts having a greater extension in the circumferential direction than the extension of the end regions of the driver elements in the circumferential direction, the driver elements having a first lateral face and an opposite lateral face, the first lateral face being oriented in the circumferential direction in a same direction, open-edge cutouts extending in the circumferential direction receiving the cover, the opposite lateral faces of the first driver elements having a stop face for a cutout on the cover and the opposite lateral faces of the second driver elements having an open-edge cutout receiving the connecting ring.

15. The driver module as recited in claim 14 further comprising the connecting ring having cutouts complementary to the cutouts in the cover, the cutouts of the connecting ring being arranged uniformly in the circumferential direction, wherein the cutouts of the connecting ring are larger than the extension of the driver elements in the circumferential direction, but smaller than the total distance between two driver elements, the connecting ring having a third means providing a snap connection operatively connecting the cutouts with the matching cutout in the cover.

16. The driver module as recited in claim 15 wherein the matching cutout in the cover is formed by a cutout arranged in the circumferential direction and penetrated by driver elements.

17. The driver module as recited in claim 15 further comprising the third means providing the snap connection having at least one spring element, the spring element being oriented in the axial direction but acting in the circumferential direction.

18. The driver module as recited in claim 14 further comprising a ramp forming a torque limitation, the ramp being formed by a projection oriented in the axial direction and extending into the cutouts in the cover in the installed position, the ramp having a stop face oriented in the circumferential direction, which can be operationally connected with a stop face in the cover.

19. The driver module as recited in claim 14 wherein the driver elements and the cutouts in the cover and the connecting ring are located at one diameter.

20. The driver module as recited in claim 14 wherein the driver elements extend in the axial direction, and the connecting ring and the cover are disk-shaped elements.

21. A driver module for clutch assemblies comprising:

a clutch housing;

a cover, the clutch housing and the cover being connected with each other, enclosing an interior space for receiving the clutch assembly, wherein the cover is secured on the clutch housing by a connecting ring; and elastic elements pretensioning the connection; between the cover and clutch housing in the circumferential directionp; and

means between the cover and the clutch housing providing a positive connection in the circumferential direction

wherein the clutch housing has driver elements arranged at uniform intervals from each other in the circumferential direction in the-outer circumference, the driver elements having different end regions forming first driver elements and second driver elements, the first driver elements each forming a stop face in the circumferential direction on the lateral faces, the stop face acting together with complementary surfaces on a cutout in the cover, and the second driver elements having only one stop face operating in the circumferential direction, while on the opposing lateral faces of the second driver, a cutout is provided for at least partial introduction of the connecting ring for axial bracing between cover and clutch housing.
