Abstract
A friction clutch, wherein the pressure force is obtained from the interaction of two different types of spring. A plate spring, which is unable by itself to apply the pressure force for transmitting the torque, is used, and at least one additional spring, which produces a force effect in the same direction and the force of which is added to the force of the diaphragm spring, is also used.
