Abstract
A friction clutch driven plate comprises an inner hub and a sleeve mounted on the inner hub for limited relative angular movement thereto by means of splines having clearance therebetween. Side plates secured to the hub are coupled through main torsion damping springs to a friction facing carrier having friction facings. The relative angular movement between hub and sleeve is controlled by two circumferentially extending springs which are arranged to be loaded in bending during this movement. To this end seats on the hub and on the sleeve engage against abutments on the springs. The springs are located in grooves of the hub and bear against end faces of the sleeve and so act as circlips to provide axial location between the hub and the sleeve.
