FRICTION CLUTCH FOR THE DRIVETRAIN OF A MOTOR VEHICLE

A friction clutch comprises a housing arrangement (12) which is to be coupled to a drive element for common rotation about a rotational axis (A) and which is or can be at least partially filled with fluid, a first group (32) of friction elements which are coupled by means of a first friction element carrier (28) to the housing arrangement (12) for common rotation about the rotational axis (A), a second group (38) of friction elements which can be placed in frictional engagement with the friction elements (30) of the first group (32) by means of a piston element (52) and which are to be coupled by means of a second friction element carrier (40) to a driven element for common rotation about the rotational axis (A), wherein the piston element (52) divides the interior space (26) of the housing arrangement (12) into a first partial space (54), which contains the two groups (32, 38) of friction elements, and a second partial space (56) in which the fluid pressure is to be increased in relation to the fluid pressure in the first partial space (54), in order to generate an engagement force, which acts on the piston element (52), for producing the frictional engagement of the friction elements (30, 36) of the two groups (32, 38) of friction elements, wherein the piston element (52) is assigned a restoring arrangement (60) in order to generate a restoring force which acts on the piston element (52) and which counteracts the engagement force, wherein the restoring arrangement (60) comprises a wear compensation arrangement (82) for providing a restoring force for the piston element (52) which is substantially independent of a wear state of the friction elements (30, 36).
