Abstract

A clutch actuator (6), as well as a method for operating a clutch (3), between the drive motor and the transmission (1) of a motor vehicle. The clutch actuator includes a cylinder with a piston (14) and an actuator (15), such that a clutch release bearing (4), arranged co-axially to the central axis of the clutch, may be operated to apply an axial pre-tensioning force on the clutch release bearing and conduct an operating medium into the clutch actuator for axially displacing the piston and/or the clutch release bearing. To simplify a clutch actuator of this type and enhance its utilization, the clutch actuator is configured and used for generating the pre-tensioning force.
