Abstract

The clutch disc for a motor-vehicle friction clutch has a hub which defines an axis of rotation and from which there projects substantially radially a hub disc so as to be secured against rotation. On the hub there is mounted, so as to be rotatable through a limited angle of rotation, a friction lining carrier which comprises two side parts which are arranged on axially opposite sides of the hub disc and which are non-rotatably connected to each other and to the carrier. In the rotational path between the side parts and the hub disc there are arranged springs which are subjected to pressure during the relative movement of the friction lining carrier and the hub. Axially on both sides of the hub disc friction rings are arranged between the hub disc and the adjacent side parts. Between one of the two friction rings and the adjacent side part there is provided a pressure ring from which there project substantially radially several arms which are stiff in the circumferential direction of the pressure ring. The arms and/or a Belleville spring bias the pressure ring towards the friction ring. The radially external ends of the arms are fastened to the adjacent side part in a play-free rig…
