ABSTRACT:
The invention concerns an elastic clutch including a hydraulic damping device wherein a viscous damping medium is displaced through predetermined gaps upon occurrence of large angles of rotation. To that end, a cam arranged on one clutch half plunges into a capsule type displacement chamber. The cam features friction elements which in the plunging make elastic and sealing contact with the sidewalls of the capsule, thereby causing both an effective sealing of the displacement chamber and also a frictional damping which supports the hydraulic damping. The disk type second clutch half can, during operation, more freely adjust within the clutch, which simplifies the manufacture.
