The invention relates to a single-motor multi-gear hybrid electric drive system based on a single planetary gear mechanism, and belongs to the technical field of hybrid electric vehicle drive systems. The system comprises an engine input shaft which is connected with an engine and rotatably connected with a first gear; a planetary gear mechanism which comprises a sun gear, an outer gear ring, a planet gear and a planet carrier, wherein the sun gear is fixedly connected with the engine input shaft; a first clutch actuator which is positioned between the first gear and the outer gear ring so as to connect or disconnect the first gear and the outer gear ring; a differential mechanism which is in transmission connection with the planet carrier; and a motor input shaft which is connected with a motor and is provided with a third gear which is in transmission connection with the first gear. Two strands of power output by the engine and the motor are input through the sun gear and the outer gear ring respectively, the two strands of power are output to the differential mechanism from the planet carrier after being synthesized so as to drive the differential mechanism to transmit the power to the wheel end of the vehicle, the engine and the motor are jointly driven to output the maximum torque, and the power performance of the whole vehicle is greatly improved.

    本申请涉及一种基于单行星齿轮机构的单电机多档混合动力电驱系统,属于混合动力汽车驱动系统技术领域,包括发动机输入轴,其与发动机连接,并转动连接有第一齿轮;行星齿轮机构,其包括太阳轮、外齿圈、行星轮和行星轮架,太阳轮与发动机输入轴固定连接;第一离合执行器,其位于第一齿轮和外齿圈之间,以使第一齿轮和外齿圈接合或断开;差速器,其与行星轮架传动连接;电机输入轴,其与电机连接,并设有与所述第一齿轮传动连接的第三齿轮。由发动机和电机输出的两股动力分别通过太阳轮和外齿圈输入,两股动力合成后从行星轮架输出至差速器,以驱动差速器把动力传递至车辆的轮端,发动机和电机共同驱动能够输出最大扭矩,整车动力性能极大增强。
