The invention relates to a device for actuating a diaphragm spring clutch (20) for vehicles by means of a pneumatic, hydraulic, or electric actuator (24). Said device comprises a regulator which is mounted upstream from the actuator (24) and whose output control variable triggers the actuator (24). A regulator is used in order to compensate the great nonlinearity of the releasing force across the release path, which is typical for diaphragm springs. The shape of the characteristic curve of said regulator is designed such that the nonlinear course of the releasing force is at least nearly compensated by triggering the actuator (24) in an adequately synchronized manner such that the releasing force remains substantially constant across the entire release path.
