Abstract

A clutch includes a hub and a flange located radially inside and outside, respectively, with respect to the clutch rotational axis and associated with hub and flange sides of the clutch. A spring elastically supports the hub and flange sides against each other in the circumferential direction in a torque-transmitting manner. A bearing radially supports the hub and flange sides against one another for rotation around the axis and includes an outer ring supporting the hub and an inner ring supported on a bearing pin associated with the flange side. A friction device connects the hub and flange sides in a friction-locked and torque-transmitting manner in the circumferential direction and includes a friction element and a friction surface which are pretensioned against one another in the axial direction. A tensioning device includes a tensioning element that applies force to, and axially pretensions, the friction device and bearing.
