Abstract
The clutch disc for a motor vehicle friction clutch includes a hub (3) having a radially protruding hub flange (7), and two side plates (9, 11) rigidly connected together and limitedly rotatably mounted on the hub (3) on axially opposite sides of the hub flange (7). Compression springs of a torsion spring damper are arranged in windows of the hub flange (7) and of the side plates (9, 11). An idling operation friction damper (51, 59) and a load operation friction damper (99, 103, 105, 107) are arranged between the two side plates (9, 11). A control element (29) renders the two friction dampers effective in alternation. The control element (29) comprises two ring parts (31, 33) connected to rotate with one another. A friction ring (51) and a presser spring (59) of the idling friction damper are accommodated between the two ring parts (31, 33). Friction rings (61, 65) and a pressure spring (71) of the load friction damper are located between the side plates (9, 11) and the ring parts (31, 33) of the control element (29). The spring (71) of the load friction damper is stronger than the spring (59) of the idling friction damper. Likewise the friction torque of the load friction damper i…
