The invention discloses a hybrid electric vehicle power transmission system and a power transmission method thereof. The system comprises an engine, a gearbox, a torsion damper, a motor output shaft and a motor, the gearbox comprises an input shaft and an output shaft, and the input shaft is fixedly connected with the driven end of the torsion damper; the input shaft is sleeved with a first driving gear and a second driving gear in a spaced mode. The first driving gear and the second driving gear are each provided with a joint gear ring, the first bilateral synchronizer is located between thefirst driving gear and the second driving gear and connected with the input shaft, and the input shaft is connected with or separated from the first driving gear and the second driving gear through left-right movement of a joint sleeve of the first bilateral synchronizer. The problem of power interruption in the gear shifting process of the gearbox is solved, and meanwhile four-gear engine driving, three-gear pure electric driving, two-mode parking power generation and engine starting are achieved.

    本发明公开了一种混合动力汽车动力传动系统及其动力传递方法。包括发动机、变速箱、扭转减振器、电机输出轴和电机,所述变速箱包括输入轴和输出轴,所述输入轴与扭转减振器从动端固连;所述输入轴上空套第一主动齿轮和第二主动齿轮,所述第一主动齿轮和第二主动齿轮均有接合齿圈,第一双边同步器位于所述第一主动齿轮和第二主动齿轮之间,且与输入轴连接,通过第一双边同步器接合套左右移动实现输入轴与第一主动齿轮和第二主动齿轮的接合或分离;本发明解决了变速箱换挡过程动力中断问题,同时实现4档发动机驱动、3档纯电驱动、2模式停车发电和发动机启动。
