ABSTRACT:
The invention concerns a device for actuating a diaphragm spring clutch (20) for vehicles by means of a pneumatic, hydraulic or electric actuator (24), comprising a controller connected upstream of the actuator (24), whose output control variable actuates the actuator (24). To compensate for the strong nonlinearity of the releasing force over the releasing stroke that is typical of diaphragm springs, a controller is used, whose characteristic curve is plotted in such a way that this nonlinear curve of the releasing force is at least approximately compensated via a correspondingly coordinated actuation of the actuator (24), so that it remains essentially identical over the releasing stroke.
