ABSTRACT:
A driven plate for a friction clutch of a vehicle and which includes a pair of annular friction facings carried on an inner portion of the driven plate by a plurality of resilient cushioning elements, attached to and disposed in a circumferential array around the inner portion of the driven plate. The friction facings are secured one on each side of the resilient cushioning elements so that the friction facings are held generally parallel to each other. The cushioning elements are fashioned so that when the driven plate in use, is clamped between a vehicle flywheel and pressure plate then the forces acting within each cushioning element are distributed such that the cushioning element provides a stiffer spring means between the outer peripheral portions of the friction facings than between the radially inner peripheral portions of the friction facings and this stiffer spring means decreases continuously across the width of the friction facing until it reaches a minimum at the radially inner periphery of the friction facings.
