Coupling device e.g. normally engaged single clutch, has spindle drive rotatably supported by spindle support device that includes safety catch operated on drive pinion for locking against reverse rotation of pinion

摘要

The device (1) has a torque transmission device (2) frictionally engaged in an engaged condition and engaged and disengaged in an axial direction. A wear adjusting device (3) includes a spindle drive (7) that is operated on a rotatable adjusting ring (14). A drive handle (5) is pretensioned against a drive pinion (6) of the spindle drive for rotation of the pinion in case of wear. The spindle drive is rotatably supported by a spindle support device (8) i.e. dual plate, that includes a safety catch (9) operated on the pinion for locking against reverse rotation of the pinion.
