BALANCING DEVICE FOR HYBRID OUTPUT POWER AND CONTROL MOTHOD THEREOF

摘要

A balancing device for hybrid output power and the control mothod thereof are provided. The balancing device for hybrid output power includes an engine (5), a large electric motor (2), a small electric motor (1), a battery, a power coupling device and multiple brakes. The coupling device is a planetary gearing containing a planet carrier, planets, long planets, a small sun gear, a large sun gear and an outer annulus gear. The power output shaft of the engine (5) is connected with the revolving shaft of the planet carrier. The planets on the planet carrier mesh with the small sun gear respectively. The small sun gear and the small electric motor (1) have the same revolving shaft. The planets on the planet carrier mesh with the long planets respectively, and the long planets mesh with the large sun gear respectively. A brake (3) for the samll electric motor is provided on the revolving shaft of the small sun gear, and an engine brake (4) is provided on the planet carrier.
