Abstract

A clutch-actuating device for a clutch in a motor vehicle power train has an actuator motor driving an actuating member and a transfer mechanism which transmits the movement of the actuating member to a clutch release element that is movable against an opposing force of a clutch spring to displace the clutch from a closed position to an open position. The transfer mechanism has a first movement range in which the movement of the actuating member in the opening direction of the clutch does not displace the clutch from its closed position, and a second movement range in which the movement of the actuating member causes a displacement of the clutch. The transfer mechanism has an interval of loose play, which is used up within the first range.
