Abstract
A friction clutch with an actuator for automated operation, having an electronic control system preferably located separately from the actuator. Whereby to reduce the intensity of the control currents for the electric motor of the actuator, there can be a compensating spring which assists the actuation force of the friction clutch, a mechanism which automatically compensates for wear inside the friction clutch, an optimally-efficient, helical spur gear with involute gear teeth, as well as a device to reduce the release force of the friction clutch.
