Patent ID: 8261900

Claim:
A wet clutch, comprising at least one friction disk ( 10 , 10 a , 10 b ) arranged in a first housing ( 2 ) and a second housing ( 2 A) and loaded by an axially movable piston ( 5 ) against at least one end disk, the at least one end disk: separate from the first and second housings; fixedly connected to the first housing such that the at least one end disk cannot move relative to the first and second housings; and forming a support for the piston ( 5 ), wherein: the at least one friction disk ( 10 , 10 a , 10 b ) is supported radially within at least one friction surface ( 11 , 12 , 13 , 14 ) providing a frictional engagement between the at least one friction disk ( 10 , 10 a , 10 b ), the piston ( 5 ) and the at least one end disk for the closed wet clutch ( 1 , 1 a , 1 b , 1 c , 1 d , 1 e , 1 f ); the support for the at least one friction disk is provided torque-proof through a profile ( 17 ) at a complementary profile ( 18 ) of a drive component ( 19 ) of the wet clutch the at least one friction surface ( 11 , 12 , 13 , 14 ) at least in non-opened condition of the wet clutch ( 1 , 1 a , 1 b , 1 c , 1 d , 1 e , 1 f ) defines two pressure cavities ( 7 , 8 ) so that a forced pressure medium flow is run over the at least one friction surface ( 11 , 12 , 13 , 14 ) by adjusting variable pressures of the pressure medium; and, a leakage flow between the two pressure cavities ( 7 , 8 ) over the profiles ( 17 , 18 ) is limited by at least one seal device located radially inward of the at least one end disk.
