The invention belongs to the technical field of hybrid electric vehicles, and particularly relates to a double-gear-shifting series-parallel hybrid power system capable of switching between input shunting and output shunting, which comprises an engine, a first motor, a second motor, a first clutch, a second clutch, a planet row, a gear shifting system and a power output shaft. A sixth gear, a seventh gear and a power switching device are arranged on the power output shaft; a power output shaft of the engine is connected with the planet carrier through the first clutch; the power output end ofthe first motor is connected with the gear ring; the power output end of the second motor is connected with the sun gear through the second clutch; and the outer gear ring gear is engaged with the sixth gear or the fourth gear is engaged with the seventh gear through the power switching device. The vehicle can enter the input shunting mode during low-speed running in the running process and can betimely switched to the output shunting mode during high-speed running of the vehicle, so that the global efficiency of the vehicle is ensured.

    本发明属于混合动力汽车技术领域,具体涉及一种在输入、输出分流式切换的双换挡混联式混合动力系统,包括发动机、第一电机、第二电机、第一离合器、第二离合器、行星排、换挡系统、动力输出轴;第六齿轮、第七齿轮、动力切换装置设置在动力输出轴上;所述发动机的动力输出轴通过第一离合器与行星架相连;第一电动机的动力输出端与齿圈相连;第二电机的动力输出端通过第二离合器与太阳轮连接;通过动力切换装置实现外齿圈齿轮与第六齿轮啮合或者第四齿轮与第七齿轮啮合。本发明可使车辆在行驶过程中,低速运行时进入输入分流模式,在车辆高速运行时及时切换到输出分流模式中,保证汽车的全局效率。
