Placement of an auxilliary mass damper to eliminate torsional resonances in driving range in a parallel-series hybrid system

摘要

A damper system for hybrid vehicles powered by an internal combustion engine and an electrical motor, and the damper system is located between the gear system and the electrical motor. The damper system connects the electrical motor to a hub ring attached to a pair of cover plates, which are separated by a plurality of spacer bolts. A flange, which is placed between the cover plates, connects to a shaft attached to the gear system via another hub ring. The flange has a plurality of windows for locating coil springs. The inertia of the electrical motor is linked to the inertia of the gear system through the coil springs.
