ACTUATION DEVICE FOR CLUTCHES

摘要

The invention relates to an actuation device (3) for clutches (2), in particular clutches in the drive train of a motor vehicle between the drive motor and a gearbox, comprising an actuator unit (6) having a drive (4) and actuating devices (5) and acting upon the clutch (2), an adjustment device (1) which is active within the effective path formed by the actuator unit (6) for compensating at least wear-related deviations of the characteristics of the clutch. The invention is characterized in that the adjustment device (1) is arranged and designed in such a manner that it can be controlled by a control/regulation device (7) corresponding to a prescribed target value and independently from the actual occurrence of wear-related deviations of characteristics.
