The invention discloses an electric vehicle rear axle assembly controlled by double motors, which comprises a rear axle. The rear axle is provided with a first motor and a second motor. The first motor is connected with a first power transmission shaft; a second power transmission shaft is arranged on the second motor; the output end of the first power transmission shaft and the output end of thesecond power transmission shaft are connected with two half shafts on a driving rear shaft respectively; a first axle housing and a second axle housing are arranged on the rear axle; a first differential mechanism and a second differential mechanism are arranged in the first axle housing and the second axle housing respectively; and a plurality of heat dissipation holes are formed in the first axle housing and the second axle housing respectively. According to the electric vehicle rear axle assembly controlled by the double motors, through the combination of the double-motor structure, the power transmission shaft, the axle housing and other structures, the electric vehicle rear axle assembly has the advantages of being high in driving capacity, large in bearing capacity, long in driving mileage, stable in braking and the like.

    本发明公开了一种采用双电机控制的电动车后桥总成,包括后桥,发明后桥设置有第一电机和第二电机,第一电机上连接设有第一动力传输轴,第二电机上设有第二动力传输轴,第一动力传输轴和第二动力传输轴的输出端分别与连接驱动后轴上的两个半轴,后桥上设有第一桥壳和第二桥壳,第一桥壳和第二桥壳内部分别设有第一差速器和第二差速器,第一桥壳和第二桥壳上均设有若干散热孔。本发明一种采用双电机控制的电动车后桥总成通过双电机的结构与动力传输轴、桥壳等结构的结合,具备驱动能力高、承载力大,行驶里程长以及制动平稳等多项优点。
