Adjustment device for use in friction clutch, has spindle nut axially displaced during rotation of spindle, where supporting moment of spindle nut countered during rotation of spindle is supported at adjusting ring

摘要

The device (1) has an adjusting ring (5) rotatably accommodated on ramps (3) of a press plate (2) by complementary counter ramps (4), where the ramps are arranged in a circumferential direction. A spindle drive (7) is attached to the pressing plate directly or by a holder (10). A spindle nut (12) is accommodated on a spindle (9) and rotatably drives the adjusting ring. The spindle nut is axially displaced during rotation of the spindle, where support moment of the spindle nut countered during rotation of the spindle is supported at the adjusting ring.
