ABSTRACT:
A friction clutch driven plate comprises an annular friction facing carrier which is mounted upon a hub assembly. Arcuate recesses are formed in the outer periphery of the hub assembly and receive rivets 32 which project from the carrier. Coil springs of square cross-section wire are supported eccentrically upon rivets, which are carried by the hub assembly, and have tangs at each end which both project outwardly between a respective pair of rivets which are carried by the hub assembly. Rotation of the hub assembly in either angular direction relative to the hub assembly is limited positively by abutment of the appropriate end of the arcuate recesses with the rivets which are received in those recesses. Those rivets deflect the trailing tang of each coil spring towards the other tang of that coil spring, which abuts the adjacent one of the rivets that are carried by the hub assembly, so that initial take up of drive through the friction clutch or torque reversal through the friction clutch, is cushioned by the coil springs.
