TORSIONAL DAMPER OF VEHICLE

摘要

PURPOSE: A torsional damper of a vehicle is provided to reduce an axial direction vibration without causing deterioration of elastic force caused due to the frictional heat generated during crank shaft vibration damping operation. CONSTITUTION: A torsional damper comprises an elastic member(4) constituted by a plate spring where a damper assembly(3) arranged in the region of a hub(2) of a crank pulley(1) is fixed within the crank pulley; a damper mass(5) fixed to an end of the elastic member; and a stopper(6) for supporting the elastic member, which has both ends attached within the crank pulley. The plate spring is made of an elastic material, and the elastic member is fixed to the crank pulley, at an angle of 45 degrees.
