TORSIONAL VIBRATION DAMPER OF VEHICLE

摘要

PURPOSE: A torsion vibration damper is provided to apply variable hysteresis varied by hysteresis according to the rotation angle of a drive plate, thereby absorbing the optimum vibration. CONSTITUTION: A torsion vibration damper of cars includes a first mass body(1), a second mass body(3), a damper unit(5), and a friction unit(21). The first mass body is combined to the output shaft(7) of an engine. The second mass body relatively rotates and moves about the first mass body. The second mass body is combined to input shaft(9) of transmission. The damper unit is installed between the first mass body and the second mass body. The damper unit absorbs vibration and impact occurred to columnar direction. The friction unit applies the friction force between the first mass body and the second mass body.
