  • Patent number: 5305864
    Abstract: A motor vehicle clutch disc includes a metal carrier sheet; an elastomer intermediate layer facing the metal carrier layer; a clutch lining facing the elastomer intermediate layer; and a composite binder bonding first surface regions of the elastomer intermediate layer to the metal carrier sheet and to the clutch lining by chemical sorption. Areas of the first surface regions are less than areas of the metal carrier sheet and the clutch lining facing the elastomer intermediate layer. The elastomer intermediate layer is of hydrated nitrile rubber or a fluoroelastomer. The elastomer intermediate layer has an elasticity of non-linear spring characteristics and is effective in a direction perpendicular to the plane of the clutch disc. The elastomer intermediate layer has unbonded, second surface regions facing the metal carrier sheet and the clutch lining.
