Actuating device for a friction clutch device, possibly a dual or multiple friction clutch device

An actuating device as in claim 4 wherein one of said support element and said actuating element has an essentially cylindrical outside surface with one of a single flight and a multi-flight external thread, the other of said support element and said actuating element having an essentially cylindrical inside surface with a respective one of a single flight and a multi-flight internal thread which engages said external thread by one of direct sliding engagement and at least one rolling element and at least one sliding element.

An actuating device as in 28 further comprising a toothed wheel gearing system for connecting said actuator and said actuating element for rotation in common.

An actuating assembly for a friction clutch device installed in the drive train of a motor vehicle between a drive unit and a transmission , said friction clutch device comprising at least one friction clutch, said actuating assembly comprising:

• an actuating unit comprising a support element which is fixed in the axial direction, at least one actuating element which engages said support element and can translate axially relative to said support element in order to actuate a respective said friction clutch, and at least one actuator assigned to a respective said at least one clutch for shifting a respective said at least one actuating element axially relative to the support element, and
• a transmission-side mount comprising a mounting receptacle which can be attached nonrotatably to the transmission and having an inside surface, and a plug-in section fixed to said support element and insertable axially into said mounting receptacle and having an outside surface which can be supported against rotation on said inside surface.

A friction clutch device for installation in the drive train of a motor vehicle between a drive unit and a transmission, said friction clutch device comprising:

• a housing which can be connected to said drive unit for rotation in common about an axis of rotation, said housing having a support area,
• at least one friction clutch assigned to a respective at least one transmission input shaft, said friction clutch comprising a pressure plate which rotates with said housing and a clutch disk having a friction area which can be pushed against said support area by said pressure plate, and
• an actuating device comprising a support element which is fixed in the axial direction, at least one actuating element which engages said support element and can translate axially relative to said support element in order to actuate a respective said friction clutch, and at least one actuator assigned to a respective said at least one clutch for shifting a respective said at least one actuating element axially relative to the support element.

A friction clutch device for installation in the drive train of a motor vehicle between a drive unit and a transmission, said friction clutch device comprising:

• at least one hydraulically operated friction clutch assigned to a transmission input shaft, and
• an actuating device comprising a support element which is fixed in the axial direction, at least one actuating element which engages said support element and can shift axially relative to said support element in order to actuate said friction clutch, and at least one actuator assigned to a respective said at least one clutch for shifting a respective said at least one actuating element axially relative to the support element.
