Friction clutch for use in double clutch, has ramp system arranged between pressure plate and lever spring, and gear attached to lever spring in circumferential direction and centrally arranged at housing

摘要

The clutch (2) has a clutch disk with friction linings deformable between clutch pressure and backpressure plates against an action of a lever spring (5). The lever spring has a sensor spring (15) for stroke-dependent sensing of wear of the friction linings, where the sensor spring is equipped with a worm gear (16) i.e. two-piece worm gear, that transmits wear from the sensor spring to a ramp system. The ramp system is arranged between the pressure plate and the lever spring, and the gear is attached to the lever spring in a circumferential direction and is centrally arranged at a housing (4).
