Abstract

Abstract Clutch disc includes a hub, an entrainer plate coaxially mounted on and turnable relative to the hub, a pair of friction linings mounted coaxially to one another on the hub adjacent the entrainer plate, a cover disc coaxially mounted on the hub in spaced relationship to the entrainer plate which is turnable relative thereto, rivet means connecting the cover disc to the entrainer plate, a damping device disposed in a force transmission path between the pair of friction linings, on the one hand, and between the entrainer plate and the hub, on the other hand, the damping device comprising force storing means operatively connected to the hub and to the entrainer plate, damping lining means coaxially mounted on the hub, and a spring member in stressing engagement with the damping lining means for frictionally connecting the latter to the entrainer plate, the spring member being coaxially mounted on the hub between the relatively turnable entrainer plate and cover disc, the spring member having an annular surface engaging the damping lining means and having means engageable with a peripheral contour of the rivet means interconnecting the entrainer disc and the cover disc for securing the spring member, at a location radially beyond the damping lining means, against turning.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 258 words
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.
Claim 2
Dependent Claim 258 words
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.
Claim 3
Dependent Claim 22 words
Clutch disc according to claim 1, wherein said spring member and said arms thereof abut a collar respectively formed on said rivets.
Claim 4
Dependent Claim 32 words
Clutch disc according to claim 1, wherein part of said spring member stands away in a given direction from a given plane in which the remainder of said spring member is disposed.
Claim 5
Dependent Claim 20 words
Clutch disc according to claim 2, wherein said spring member is in prestressing engagement with said collars of said rivets.
Claim 6
Dependent Claim 23 words
Clutch disc according to claim 1, wherein said spring element is prestressed substantially uniformly over said path of wear of said damping linings.
