  • Device for preventing vibration of a pressure plate of a friction clutch of a vehicle
    Patent number: 4114740
    Abstract: A friction clutch having a flywheel, a pressure plate, an entrainer disc disposed in the space between the flywheel and the pressure plate and splined on an input shaft of a transmission, and a clutch plate spring for engaging the pressure plate, adapted for transmitting torque from the flywheel by resiliently clamping the entrainer disc, and characterized by provision for a resilient, vibration-dampening member which serves to normally urge the pressure plate to be displaced from the flywheel by the stored elastic energy of the resilient member.
