Abstract

The clutch disc for a motor vehicle friction clutch comprises a hub with side discs arranged axially on both sides of its hub flange and connected with friction linings into one unit. The side discs are rotatable in relation to the hub disc by the stressing of springs. An under-load friction damper comprises two control discs arranged axially on both sides of the hub disc, one of which comprises axial tabs which pass through openings of the hub disc. The other control disc is guided non-rotatably but axially displaceably on the tabs. Friction rings are arranged axially between the side discs on the one part and the control discs on the other. The friction force is generated by a dished spring which is clamped axially resiliently in between the axial tabs of the one control disc and the axially movable other control disc utilized as pressure disc. An idling friction damper is accommodated between the side discs protected radially within the zone radially defined by the tabs.
