ABSTRACT:
A pressure plate arrangement for a friction clutch includes a housing rotatably fixed to an abutment arrangement for joint rotation about an axis of rotation and a plate arrangement with at least one intermediate plate and a pressure plate. At least one of the intermediate and pressure plates is mounted in the housing and axially movable relative thereto and rotateable about the axis of rotation. An energy storage device coupled to the housing generates an elastic restoring force on the plate arrangement. A releasing spring arrangement located between the housing and plate arrangement is tensioned to generate an elastic restoring force on the pressure plate in a second direction opposite to the first direction. A clutch disk arrangement is clamped between the abutment arrangement and the at least one intermediate plate, or between any two plates of the plate arrangement.
