Actuating device for a friction clutch for a motor vehicle

摘要

The device has a preferably hydraulic actuating element (10) that interacts with a force transfer element (12) to apply an actuating force to the clutch and a sensing device (16) for detecting a parameter representative of the engaged/disengaged state and/or the state of wear of the friction clutch. A sensor (18) detects the force of a spring (14) for biasing the force transfer element or a parallel spring as the representative parameter.
