The invention relates to a coaxial single-motor three-gear sequence gear shifting electric drive axle system which comprises a driving motor, a three-gear planetary speed reducing mechanism, a gear shifting mechanism and a differential mechanism assembly. According to the technical scheme, large-torque output and high-rotating-speed operation can be achieved only through the three-stage series planet row, meanwhile, sequence switching of three gears without power interruption can be achieved only through the gear shifting actuator and the gear shifting gear sleeve, the transmission efficiency of the electric drive axle system is greatly improved, and meanwhile the cost of the whole machine is reduced.

    本发明涉及一种同轴式单电机三档序列换档电驱桥系统,包括驱动电机、三档行星减速机构、换档机构及差速器总成;本发明的技术方案中仅采用三级串联的行星排即可实现大扭矩输出和高转速运行,同时仅采用一个换档执行器和换档齿套就能实现三个档位无动力中断的序列切换,大大提高了电驱桥系统的传动效率,同时降低了整机的成本。
