Abstract:
A clutch disc wherein two annular washer-like friction linings flank a two-part resilient cushion which moves the friction linings apart during disengagement of a friction clutch wherein the clutch disc is installed between an engine-driven flywheel and an axially movable pressure plate, and which stores energy during engagement of the clutch. A blocking or movement limiting device, which defines a fulcrum for the friction linings, is provided between the parts of the cushion and/or on the friction linings to prevent an axial movement of the friction linings toward each other beyond a selected minimum distance and to thus compensate for deformation of the flywheel and/or pressure plate as a result of heating attributable to slippage of the pressure plate and flywheel relative to the adjacent friction linings during engagement and disengagement of the clutch.
