Abstract

An actuating device for a friction clutch device installed in the drive train of a motor vehicle introduces actuating forces, especially clutch-engaging or clutch-releasing forces, to the friction clutch device to actuate at least one friction clutch of the friction clutch device in the engaging or releasing direction. At least one actuating element assigned to a friction clutch can be shifted axially relative to at least one support element, which is essentially fixed in the axial direction, to exert the actuating forces. The actuating element belongs to an actuator assigned to the clutch or can be shifted axially relative to the support element by the intermediate action of an actuator assigned to the clutch. The actuating element and the support element engage with each other in such a way that a rotational movement of the actuating element relative to the nonrotatably supported support element, this movement being imparted by the intermediate action of the actuator, is converted to an axial translational movement of the actuating element relative to the axially supported support element.
