Rotary vibration damper having two coaxial parts for vehicle - has single friction unit axially clamped between friction faces and having anti-wear means to prevent sliding contact.

摘要

The friction unit (5) has an elastic element (50) provided on at least one side face for fixing with a friction disc (52) for friction contact with the first friction face (61). The friction unit is clamped between the first friction face (61) and a second side face (60) which is fixed to the other of the second and first parts (2,1). The anti-wear means (52) are provided on the inside between the second part (60) and the plastics element (50). The plastics element is a ring block of elastic material with recesses formed as radially aligned blind holes opening on the outer periphery of the block or axially aligned blind holes opening axially into an opening in one of the friction discs. USE/ADVANTAGE - Easier installation of rotary damper for vehicle. The first and second faces are continuous providing stronger damping.
