Abstract
The clutch disc for a motor vehicle friction clutch comprises a hub (1) on which side discs (7, 9) are rotatably mounted, arranged axially spaced, rigidly joined together, carrying the clutch linings (17). A hub plate (19) joined with the hub (1) solid in rotation, but with rotary play, is coupled rotationally elastically by means of springs (23) with the side discs (7, 9). Mounted axially between the hub plate (19) and one of the side discs (7) is a friction ring (41) of plastic material from which there protrude lugs (39) engaging into recesses (61) of the side disc (7). The lugs (39) guide the friction ring (41) solid in rotation but axially movable on the lateral disc (7). Axially mounted between the frictional ring (41) in frictional contact with the hub plate (19) and the side disc (7) is a disc spring (43) which applies with a plurality of flexible tongues protruding from its inner circumference on the friction ring (41). The flexible tongues engage in recesses of the friction ring (41). The friction ring carries on its inner circumference radially springing clamps (63) over which, together with the disc spring (43) it can be mounted by snapping on the side disc (7) or on a constructional part connected with the side disc (7).
