The clutch disc for a friction disc clutch comprises friction linings attached to a lining carrier by connection elements. The connection elements are provided with a synthetic plastics conical head, seated in a conical opening of the friction lining. A shank, on the side of the lining carrier turned away from the friction lining, has been deformed into a closing head. The portion of the shank forming the closing head can consist of synthetic plastics, too, or can be formed by a metal hollow rivet anchored in the head. The synthetic plastics head wears out along with, and increases, the wearable volume of the friction lining.

Clutch disc for a friction disc clutch

For the snap connection of a clutch releaser with spring tongue ends of a diaphragm spring in a pulled-type diaphragm spring clutch, there is secured to the spring tongue ends a first ring part which comprises a radially inwardly protruding first stop ring shoulder directed axially away from the releaser. With the releaser there is connected a second ring part which comprises a radially outwardly protruding second stop ring shoulder directed axially to the releaser and is insertable, with the second stop ring shoulder leading, through beneath the first stop ring shoulder axially into the first ring part. On the side of the first ring shoulder axially remote from the releaser a radially elastic wire ring is arranged which snaps over the second ring shoulder in the insertion of the second ring part. A support ring is axially fixedly inserted into the first ring part and axially supports the wire ring on a ring shoulder in the insertion of the second ring part. The support ring is held by retaining tabs on the first ring part, each of which comprises at least one spring tongue which rests from radially outwards on the wire ring and centers the wire ring for the insertion of the second ring part.
