Rotary joint for use in roll stabilizer for chassis of motor vehicle, has coil spring pressing friction element against driven part for frictional driving of driven part, where actuation of friction element takes place from breakaway torque

摘要

The joint has a friction element (5) i.e. friction case (21), comprising two friction portions (19) where one friction portion is in frictional contact with a coil spring (4) and another friction portion is in frictional contact with a frame-mounted element (3) i.e. housing. The coil spring presses the friction element against a driven part (2) i.e. shaft (9), for frictional driving of the driven part by changing diameter of the friction element, where actuation of the friction element takes place from a breakaway torque. The coil spring is pre-tensioned on the friction element. An independent claim is also included for a roll stabilizer.
