The invention relates to the technical field of electric vehicle axles, and provides a multi-gear variable-speed electric axle which comprises a motor, a clutch, a transmission, a drive axle and a hydraulic control system, power output by the motor is transmitted to the drive axle through the clutch and the transmission in sequence, and a hydraulic control system is also included and is used for controlling the clutch and the transmission to conduct gear shifting operation. By means of the technical scheme, the problems that in order to meet the vehicle driving requirement, a high-power motoris adopted in an electric vehicle drive axle in the prior art, motor performance cannot be fully utilized, and energy consumption is high are solved.

    本发明涉及电动车桥技术领域,提出了一种多挡变速电动车桥,包括电机、离合器、变速器和驱动桥,电机输出动力依次通过离合器和变速器传递至驱动桥,还包括液压控制系统,液压控制系统用于控制离合器和变速器以进行换挡操作。通过上述技术方案,解决了现有技术中的电动车驱动桥为满足车辆行驶需要,采用大功率电机,无法充分利用电机性能、耗能较高的问题。
