ABSTRACT:
A multiple-disc friction clutch wherein two axially movable pressure plates are disposed between two clutch plates and flank a diaphragm spring whose circumferentially complete outer marginal portion engages one of the pressure plates and which has a second portion located radially inwardly of the marginal portion and engaging the other pressure plate. The second portion of the diaphragm spring has a circumferentially complete tension spring which stores energy in addition to that stored in the outer marginal portion. The tension spring is located radially inwardly of the regions where the second portion engages the other pressure plate.
