Adjustment device for adjusting wear-related failure distance between pressure and counter plates of friction clutch of motor car, has pawl device with drive pawl that is engaged into pinion of drive, and another drive rotating ramp part

摘要

The device (10) has an adjustable drive (26) relatively rotating a ramp part (14) in a circumferential direction to a counter ramp (20) of another ramp part (18). The ramp parts are rotatably mounted with respect to a pressing plate (22) of a friction clutch. The latter ramp part is provided with the counter ramp to a ramp (16). A pawl device is supported at a cover of the clutch. The pawl device comprises a drive pawl that is engaged into a pinion (30) of an adjustable drive for rotation of the pinion. Another adjustable drive (28) rotates the latter ramp part. The pawl device is designed as a pawl plate. The ramp parts are designed as ramp rings. The adjustable drives are designed as jackscrew actuators.
