The invention discloses a multi-gear hybrid power driving system which comprises an engine, a planetary gear mechanism, a first clutch, a second clutch, a motor, a gear transmission mechanism, a gear shifting mechanism and an output shaft. The second clutch is connected with a sun gear of the planetary gear mechanism and used for locking the sun gear. According to the multi-gear hybrid power driving system, in the hybrid power generation driving mode, the power split type power generation mode and the two-gear direct driving mode are achieved by controlling opening and closing of the first clutch and the second clutch, the better power performance of the whole vehicle can be achieved, meanwhile, loss in the direct driving mode can be reduced, and the service life of the whole vehicle is prolonged. The multi-gear hybrid power driving system is more efficient; and only one motor is used, so that the cost is reduced, and the economic applicability of the multi-gear hybrid power driving system is improved.
本发明公开了多挡混合动力驱动系统,包括:发动机、行星齿轮机构、第一离合器、第二离合器、电机、齿轮传动机构、换挡机构和输出轴,第一离合器与行星齿轮机构的行星架相连,用以对行星齿轮结构进行锁止,第二离合器与行星齿轮机构的太阳轮相连,用以对太阳轮进行锁止。本发明提供的多挡混合动力驱动系统,在混动发电驱动模式下,通过控制第一离合器和第二离合器的开合,实现功率分流型发电模式和两挡直接驱动模式,既能够使整车实现更好的动力性,同时能够降低直驱模式下的损耗,使多挡混合动力驱动系统更加高效;只使用一台电机,降低成本,提高多挡混合动力驱动系统的经济适用性。
