  • Clutch plate for a motor vehicle friction clutch
    Patent number: 5251736
    Abstract: A clutch plate for a motor vehicle friction clutch is proposed in which a lateral disc of a load torsional vibration damper of the clutch plate is radially centered on spring tongues which extend and project either axially or peripherally from a hub of the clutch plate. The spring tongues extend into a central opening in the lateral disc, and the spring tongues rest in the central opening under radial tension. Radially acting stops on the hub can be provided peripherally between the individual spring tongues to limit the spring travel.
