Abstract

The present invention relates to a disk clutch ( 2 ) comprising a first disk carrier ( 18 ), a second disk carrier ( 24 ), and a disk set ( 34 ) assigned to the first and second disk carriers ( 18, 24 ), wherein the first and second disk carriers ( 18, 24 ) may be brought in a friction-locking way into rotary driving connection with one another via the disk set ( 34 ), and the first and the second disk carrier ( 18, 24 ) may additionally be brought in a positive-locking way into rotary driving connection with one another.

First claim

The invention claimed is:

wherein the first and second disk carriers ( 18 , 24 ) are brought in a friction-locking way into rotary driving connection with one another by an actuating device ( 46 ), by means of which an actuating force ( 60 ) is applied on the disk set ( 34 ), wherein the first and second disk carriers ( 18 , 24 ) are additionally brought in a positive-locking way into rotary driving connection with one another via the actuating device ( 46 ),
wherein the actuating device ( 46 ) is in positive-locking rotary driving connection with the first disk carrier ( 18 ), and
wherein the actuating device ( 46 ) is brought into rotary driving engagement in a positively-locking way with an end disk ( 42 ) of the disk set ( 34 ) to achieve the positive-locking rotary driving connection between the first and second disk carriers ( 18 , 24 ).

2. The disk clutch ( 2 ) according to claim 1 , wherein the actuating device ( 46 ) is brought into rotary driving engagement in a positively-locking way with a toothing ( 106 ) of the end disk ( 42 ), said toothing being in rotary driving engagement with the second disk carrier ( 24 ), a toothing section of the second disk carrier ( 24 ), or a disk support section ( 30 ) of the second disk carrier ( 24 ).

3. The disk clutch ( 2 ) according to claim 2 , wherein said toothing being designed as wider than the toothing of the other disks ( 36 , 38 , 40 ) of the disk set ( 34 ) with respect to an axis of rotation ( 16 ) of the disk set ( 34 ).

4. The disk clutch ( 2 ) according to claim 1 , wherein the actuating device ( 46 ) is displaceable from a first position, in which the first and second disk carriers ( 18 , 24 ) are decoupled from one another, into a second position, in which a frictional connection exists between the first and second disk carriers ( 18 , 24 ) via the disk set ( 34 ), and the actuating device ( 46 ) is additionally displaceable from the second position into a third position, in which the first and second disk carriers ( 18 , 24 ) are in positive-locking rotary driving connection with one another via the actuating device ( 46 ).

5. The disk clutch ( 2 ) according to claim 4 , wherein the actuating device ( 46 ) is displaceable in the same direction from the first position into the second position and from the second position into the third position.

6. The disk clutch ( 2 ) according to claim 4 , wherein the actuating device ( 46 ) has a first actuating element ( 62 ) via which the actuating force ( 60 ) is applied to the disk set ( 34 ) and a second actuating element ( 64 ) for driving the first actuating element ( 62 ) on which the first actuating element ( 62 ) is supported or supportable, and wherein by displacing the actuating device ( 46 ) from the second position into the third position, the first actuating element ( 62 ) is displaceable relative to the second actuating element ( 64 ) from an initial position into a retracted position, and the second actuating element ( 64 ) is brought in a positive-locking way into rotary driving engagement with the second disk carrier ( 24 ).

7. The disk clutch ( 2 ) according to claim 6 , wherein the second actuating element ( 64 ) is brought into a positive-locking way into rotary driving engagement with the second disk carrier ( 24 ) through a toothed section or a disk support section ( 30 ) of the second disk carrier ( 24 ).

8. The disk clutch ( 2 ) according to claim 7 , wherein the second actuating element ( 64 ) is brought into a positive-locking way into rotary driving engagement with the second disk carrier ( 24 ) through the end disk ( 42 ).

9. The disk clutch ( 2 ) according to claim 1 , wherein the actuating device ( 46 ) has a first actuating element ( 62 ) via which the actuating force ( 60 ) is applied to the disk set ( 34 ) and a second actuating element ( 64 ) for driving the first actuating element ( 62 ) on which the first actuating element ( 62 ) is supported or supportable.

10. The disk clutch ( 2 ) according to claim 9 , wherein the first actuating element ( 62 ) is supported or supportable on the second actuating element ( 64 ) via a reset device ( 94 ) for resetting the first actuating element ( 62 ) into an initial position.

11. The disk clutch ( 2 ) according to claim 10 , wherein the first actuating element ( 62 ) is displaceable counter to a reset force ( 96 ) of the reset device ( 94 ) from the initial position into the retracted position.

12. The disk clutch ( 2 ) according to claim 11 , wherein the reset device ( 94 ) has a spring device ( 98 ) to generate a spring force ( 104 ) from which the reset force ( 96 ) results.

13. The disk clutch ( 2 ) according to claim 12 , wherein the spring force ( 104 ) defines an angle of less than 45° with the resulting reset force ( 96 ).

14. The disk clutch ( 2 ) according to claim 9 , wherein the second actuating element ( 64 ) is in positive-locking rotary driving connection with the first disk carrier ( 18 ) via the first actuating element ( 62 ), and/or the first actuating element ( 62 ) is designed as disk-like and/or annular.

15. The disk clutch ( 2 ) according to claim 9 , wherein the first and second actuating elements ( 62 , 64 ) are in positive-locking rotary driving connection with one another, wherein the first actuating element ( 62 ) has a toothing ( 82 ) which is in rotary driving engagement with a toothing ( 90 ) on the second actuating element ( 64 ), and/or the first actuating element ( 62 ) is in positive-locking rotary driving connection with the first disk carrier ( 18 ), wherein the first actuating element ( 62 ) has a toothing ( 80 ) which is in rotary driving engagement with a toothed section or a disk support section ( 22 ) of the first disk carrier ( 18 ).

16. The disk clutch ( 2 ) according to claim 15 , wherein the toothing ( 90 ) on the second actuating element ( 64 ) is brought in a positive-locking way into rotary driving engagement with the end disk ( 42 ).

17. The disk clutch ( 2 ) according to claim 16 , wherein the toothing ( 90 ) on the second actuating element ( 64 ) is brought in a positive-locking way into rotary driving engagement with a toothing ( 106 ) of the end disk ( 42 ) while achieving the positive locking rotary driving connection between the first and second disk carriers ( 18 , 24 ).

18. The disk clutch ( 2 ) according to claim 15 , wherein a stop ( 102 ) is provided between the first and second actuating elements ( 62 , 64 ) via which the first actuating element ( 62 ) is supported or supportable on the second actuating element ( 64 ) in a retracted position.

19. The disk clutch ( 2 ) according to claim 18 , wherein the stop ( 102 ) is arranged detachably on the first or second actuating element ( 62 ; 64 ) and/or is designed as a retaining ring.
