The invention relates to a clutch actuator for actuating a clutch between a drive engine and a gearbox of a motor vehicle, particularly a commercial vehicle, comprising a linearly actuable RAM, which acts on a coaxial with a central axis of the clutch release unit according to the preamble of claim 1

[0002] Such clutch actuator is, for example, from DE 100 14 225 A1known. Such clutch actuator is often externally flanged to the transmission housing and has a linearly actuated RAM which is arranged parallel to the central axis of the coupling and is coupled to one end of a pivotally mounted within the clutch housing release lever, the other end of a clutch operator, such as a coaxial with the coupling central axis bearing operated. The release lever is loaded with large forces and bending moments, which is why he is generously sized and is usually designed as a forging, which in turn relatively high manufacturing costs due. In addition, the release lever provides only a small force ratio so that the clutch actuator must be wide enough.
