The invention discloses a two-gear variable-speed driving system of a plug-in hybrid electric vehicle. The two-gear variable-speed driving system comprises an engine, a first drive motor; a second drive motor; a transmission input shaft system which can be connected with the engine, the first driving motor and the second driving motor and transmit power; a transmission output shaft system which isconnected with the transmission input shaft system and transmits power; the transmission output shaft system is connected with a differential mechanism shaft system capable of outputting power to wheels; power is transmitted between the transmission input shaft system and the transmission output shaft system through a first-gear transmission gear train or a second-gear transmission gear train. Power of the engine and the two motors is coupled through the transmission input shaft system and the transmission output shaft system which are arranged in parallel. Power output in different driving modes is achieved, switching between different working modes can be achieved according to different working conditions and the electric quantity of the power battery pack, the fuel economy is improvedwhile the dynamic property of the vehicle is guaranteed, and gear shifting power interruption is avoided.

    本发明公开了一种插电式混合动力汽车的两挡变速驱动系统,包括发动机;第一驱动电机;第二驱动电机;可与发动机、第一驱动电机和第二驱动电机连接并传递动力的变速器输入轴系和与变速器输入轴系连接并传递动力的变速器输出轴系;变速器输出轴系连接有可将动力输出至车轮的差速器轴系;变速器输入轴系和变速器输出轴系之间通过一挡传动齿轮系或二挡传动齿轮系传递动力。通过平行设置的变速器输入轴系和输出轴系耦合了发动机和两个电机的动力,实现了不同驱动模式下的动力输出,并能根据不同的工况及动力电池组电量在不同的工作模式间进行切换,在保证车辆的动力性的同时提高了燃油经济性且避免了换挡动力中断。
