The invention provides a coaxial pure electric vehicle power system with a power disconnection function and a vehicle. The coaxial pure electric vehicle power system comprises a motor, a gear, an intermediate shaft assembly, a gear shifting driving mechanism, a differential mechanism assembly and an output shaft. The motor is connected with the gear and used for driving the gear to rotate; the gear, the intermediate shaft assembly and the differential mechanism assembly form a gear transmission mechanism; the intermediate shaft assembly comprises an intermediate shaft and a connecting and disconnecting gear; the gear shifting driving mechanism is used for connecting or disconnecting the connecting and disconnecting gear and the intermediate shaft; when the intermediate shaft is connected with the connecting-disconnecting gear, power is transmitted to the output shaft through the motor, the gear, the connecting-disconnecting gear, the intermediate shaft and the differential mechanism assembly in sequence. And when the intermediate shaft is disconnected with the disconnection gear, the disconnection gear idles. According to the coaxial pure electric vehicle power system with the power disconnection function and the vehicle, by disconnecting the transmission path of the intermediate shaft, the wheel end and the motor end are disconnected, the dragging torque is reduced, the energy consumption of the whole vehicle is effectively reduced, and the endurance mileage is increased.

    本发明提供了一种具有动力断开功能的同轴式纯电动汽车动力系统及汽车,包括:电机、齿轮、中间轴组件、换档驱动机构、差速器组件和输出轴;电机与齿轮连接,用于驱动齿轮转动;齿轮与中间轴组件、差速器组件组成齿轮传动机构;中间轴组件包括中间轴和接断齿轮;换档驱动机构用于使接断齿轮与中间轴连接或断开;中间轴与接断齿轮连接时,动力依次通过电机、齿轮、接断齿轮、中间轴和差速器组件传递到输出轴;中间轴与接断齿轮断开时,接断齿轮空转。本发明涉及的具有动力断开功能的同轴式纯电动汽车动力系统及汽车,通过断开中间轴传递路径,实现了轮端与电机端断开,降低了拖曳扭矩,有效的降低了整车能耗,提高了续航里程。
