Clutch disc

Claim 1

Clutch disc comprising a hub, an entrainer plate coaxially mounted on and turnable relative to said hub, a pair of friction linings mounted coaxially to one another on said hub adjacent said entrainer plate, a cover disc coaxially mounted on said hub in spaced relationship to said entrainer plate which is turnable relative thereto, rivet means comprising a plurality of peripherally spaced rivets connecting said cover disc to said entrainer plate, a damping device disposed in a force transmission path between said pair of friction linings, on the one hand, and between said entrainer plate and said hub, on the other hand, said damping device comprising force storing means operatively connected to a flange of said hub and at least to said entrainer plate, damping lining means coaxially mounted on said hub, and a spring member in stressing engagement with said damping lining means for frictionally connecting the latter to said entrainer plate, said spring member being coaxially mounted on said hub between said relatively turnable entrainer plate and cover disc, said spring member having an annular surface portion engaging said damping lining means and having radially outwardly extending arms loosely and non-clampingly engageable with a peripheral contour of said rivets individually, and interconnecting said entrainer disc and said cover disc for securing said spring member, at a location radially beyond said damping lining means, against turning, while leaving said spring member, at least in the region thereof within said damping lining means, freely movable in axial direction thereof for applying a spring force in said axial direction.
