A motor drive axle of a double-track vehicle comprises a drive motor, a differential planet set, a hub reduction gear, a steering motor, an electromagnetic brake, a center shell and a reduction bevel gear pair. The driving motor is arranged at the bottom in the center shell, the output ends of the two ends of the driving motor are connected to sun wheels of the differential planet sets, and a planet carrier of each differential planet set is connected with the hub reduction gear. A steering motor is arranged at the top of the center shell, an electromagnetic brake is arranged at the output end of the steering motor, the output end of the steering motor is connected with a speed reduction bevel gear pair, and each bevel gear is connected to outer gear rings of the two differential planet sets through gears. The planet carrier speed reduction and differential process is adopted, the whole structure is simple and small, and the steering problem of the double-track vehicle is well solved through the structure. The whole mechanical stability is high, and through braking of the electromagnetic brake, on the premise that straight movement is guaranteed, the slipping phenomenon in the straight movement process is well guaranteed.

    一种双履带车辆的电机驱动桥,包括驱动电机、差速行星组、轮边减速器、转向电机、电磁制动器、中心壳体和减速锥齿轮对;驱动电机设置在中心壳体内底部,驱动电机的两端输出端均连接到差速行星组的太阳轮,每个差速行星组的行星架均连接轮边减速器;中心壳体的顶部设置有转向电机,转向电机的输出端设置有电磁制动器,转向电机的输出端连接有减速锥齿轮对,每个锥齿轮分别通过齿轮连接到两个差速行星组的外齿圈。采用行星架减速和差速过程,整体结构简单小巧,此结构很好的解决了双履带车辆的转向问题。整个机械稳定性高,通过电磁制动器的制动,在确保直行的前提下,很好保证了在直行过程中的打滑现象。
