Abstract

A wet clutch ( 1 ) with at least one friction disk ( 8 ) that can be clamped by an axially displaceable piston ( 5 ) against an end disk ( 7 ). In order to provide a cost-effective and more silent design, the end disk is permanently attached at the housing. Several variants are proposed for the attachment of the end disk.

Claims (16)

1 . A wet clutch comprising a housing ( 6 ) driven by a drive unit and at least one friction liner ( 8 ) configured to be clamped against an end disc ( 7 , 7 a, 7 b, 7 c, 7 d, 7 e, 7 f ) through a piston ( 5 ) that is axially movable through pressure, wherein the end disc ( 7 , 7 a, 7 b, 7 c, 7 d, 7 e, 7 f ) is supported in an axially, radially and rotationally fixated manner at the housing ( 6 ).

2 . The wet clutch according to claim 1 , wherein the end disc ( 7 , 7 a, 7 b, 7 c, 7 d, 7 e, 7 f ) is circumferentially supported through friction locking or form locking at the housing ( 6 ).

3 . The wet clutch according to claim 1 , wherein the end disc ( 7 , 7 a, 7 b, 7 c, 7 d, 7 e, 7 f ) is axially supported through friction- or form locking at the housing ( 6 ).

4 . The wet clutch according to claim 1 , wherein the end disc ( 7 , 7 a, 7 b, 7 c, 7 d, 7 e, 7 f ) is permanently connected with the housing through impressing or through a plastic deformation.

5 . The wet clutch according to claim 1 , wherein the end disc ( 7 , 7 a, 7 b, 7 c, 7 e, 7 f ) is axially fixated at a stop ( 16 , 29 ) formed by at least one of two housing shells ( 14 , 17 ) of the housing ( 6 ).

6 . The wet clutch according to claim 1 , wherein the end disc ( 7 e, 7 f ) is caulked with the housing ( 6 ).

7 . The wet clutch according to claim 1 , wherein the housing ( 6 ) is roller-burnished relative to the end disc ( 7 d ).

8 . The wet clutch according to claim 1 , wherein the end disc ( 7 c ) is riveted together with the housing ( 6 ).

9 . The wet clutch according to claim 1 , wherein the end disc is attached at the housing through a wobble process.

10 . The wet clutch according to claim 1 , wherein the end disc is supported at the housing through a forging- or embossing process.

11 . The wet clutch according to claim 1 , wherein the end disc ( 7 , 7 a, 7 b, 7 d ) is received over its entire circumference at the housing ( 6 ).

12 . The wet clutch according to claim 1 , wherein the end disc ( 7 e, 7 f ) is supported relative to the housing ( 6 ) in circumferential segments at least with respect to one degree of freedom of motion freedom.

13 . The wet clutch according to claim 1 , wherein the end disc ( 7 , 7 a, 7 b, 7 c, 7 d, 7 e, 7 f ) has a planar, conical or dish shape.

14 . The wet clutch according to claim 1 , wherein end disc includes beads, embossings, and/or ribs.

15 . The wet clutch according to claim 1 , wherein the end disc ( 7 b, 7 e, 7 f ) includes at least one recess ( 22 ) or relief opening ( 34 ) at least at one circumference of the end disc or radially between circumferences of the end disc.

16 . The wet clutch according to claim 1 , wherein a material thickness varies over the circumference or in radial direction.
