HYBRID VEHICLE HAVING TORSIONAL COUPLING BETWEEN ENGINE ASSEMBLY AND MOTOR-GENERATOR

摘要

A hybrid vehicle has a power system (102) with a torsional coupling (206). The power system (102) includes a battery system (110) for receiving, storing and providing electrical power, an internal combustion engine (104) configured to provide rotational power through a flywheel (1804), a first motor-generator (106), a second motor-generator (108), a control system (202), and a torsional coupling (206). The torsional coupling (206) may absorb rotational shock caused by angular or rotational speed differences between the engine (104) and the first motor-generator (106). The torsional coupling (206) includes a driven plate assembly (1806), a cover assembly (1808) and an interconnecting plate assembly (1810). The interconnecting plate assembly (1810) may include a plurality of shock absorbing elements (1910) that absorb shock and vibration between the engine (104) and the motor-generator (106; 108).
