Actuating unit i.e. hydrostatic central releasing lever, for friction clutch at gear input shaft, has torque-limiting anti-twist device arranged between non-rotating bearing ring of self-centering roller bearing and retaining part

摘要

The unit (1) i.e. hydrostatic central releasing lever (2), has a retaining part (3) mounted at a gear input shaft and fixed at a housing (4), and an axially shiftable pressurization part (7) at which a self-centering roller bearing (10) is fixedly arranged. The bearing has a non-rotating bearing ring (14) that radially shifts opposite to the pressurization part. The bearing includes a rotating bearing ring (17) that loads a pressurization device of a friction clutch. A torque-limiting anti-twist device (19) is arranged between the non-rotating bearing ring and the retaining part.
