DUST COVERING APPARATUS OF THE TORSION DAMPER IN THE HYBRID SYSTEM

摘要

A dust cover mounting structure for a torsion damper of a hybrid vehicle system is provided to prevent breakdown of an electric motor, thereby improving reliability of the product. A dust cover mounting structure for a torsion damper(50) of a hybrid vehicle system comprises an electric motor(20), a crank shaft(11), a transmission(12), and the torsion damper. The electric motor is mounted to one side of an engine(10). The crank shaft of the engine is connected to a rotor(24) of the electric motor. The transmission is mounted to one side of the electric motor. The torsion damper reduces torsional vibration generated while driving force of the engine and the electric motor is transmitted to the transmission. The torsion damper is mounted between a motor housing and a transmission housing. A dust cover(40) is attached to the outside of a disc plate of the torsion damper, so that a damper spring(53) and a spring guide are not exposed to the outside, thereby preventing dust generated by friction between the damper spring and the spring guide from infiltrating in a gap(G) between a stator(22) and the rotor.
