The invention discloses a wide-body heavy-duty vehicle short-shaft axle based on distributed electric drive and a vehicle, the axle comprises an axle tube and electric wheel mechanisms, the electric wheel mechanisms are arranged at the two ends of the axle tube in a bilateral symmetry mode, and the electric wheel mechanism at each end comprises a motor, a planetary gear speed reducing mechanism, arim and a shell; a power output shaft of the motor is in rigid connection with the power input end of the planetary gear speed reduction mechanism, a gear ring of the planetary gear speed reduction mechanism is fixedly connected with the shell, and the power output end of the planetary gear speed reduction mechanism is in rigid connection with the rim; and power of the motor drives the rim afterbeing decelerated by the planetary gear system so as to drive the wheel to move forwards. Electric drive planetary gear transmission is used for replacing hydraulic transmission, the mechanical transmission efficiency is higher, the requirement for the machining precision of elements is relatively low, the cost is reduced, there is no hydraulic leakage risk, the maintenance-free capacity is high,the safety is higher, and the wheel is suitable for commercial vehicle wheels with double tires installed in parallel.

    本说明书公开一种基于分布式电驱动的宽体重型车辆短轴车桥及车辆,所述车桥包括桥管和电动轮机构,所述电动轮机构左右对称地设置于所述桥管的两端,每端的电动轮机构包括电机、行星齿轮减速机构、轮辋以及壳体;所述电机的动力输出轴与所述行星齿轮减速机构的动力输入端刚性连接,所述行星齿轮减速机构的齿圈与所述壳体固连,所述行星齿轮减速机构的动力输出端与所述轮辋刚性连接;所述电机的动力通过所述行星齿轮系统减速后驱动所述轮辋,以带动车轮前进。以电驱动行星齿轮传动代替液压传动,机械传动的效率更高,元件的加工精度要求相对较低,降低了成本,没有液压泄露风险,免维护能力好,安全性更高,适用于双胎并装的商用车车轮。
