Abstract

A wet clutch arrangement, particularly a wet plate clutch or lockup clutch including a first friction face formation coupled with a housing arrangement for rotation around an axis of rotation and a second friction face formation coupled with an output member for rotation around the axis of rotation, and a preferably ring-shaped pressing piston. The pressing piston, together with the housing arrangement, defines a pressure fluid space and is movable in direction of the axis of rotation through a change in fluid pressure in the pressure fluid space for influencing the frictional interaction between the friction face formations. An operant fluid application surface of the pressing piston is in the range of 15000 mm2 to 25000 mm2 for generating a force acting upon the pressing piston.
