The invention provides a differential mechanism and direct drive motor integrated rear axle assembly which comprises a direct drive motor and a differential mechanism, the direct drive motor comprisesa shell, a stator and a rotor which are sequentially arranged from outside to inside, and the rotor comprises rotor magnetic steel, rotor silicon steel sheet laminations and a rotor shaft. The differential mechanism and direct drive motor integrated rear axle assembly is characterized in that the rotor shaft of the direct drive motor is directly connected with the differential mechanism. According to the direct drive motor assembly, the differential mechanism and the motor are of an integrated structure, a gear box and a differential mechanism shell are omitted, the structure is simple and compact, the transmission efficiency is high, noise is low, the overall size of an axle is reduced, manufacturing is easier, and cost is lower.

    本发明提供了一种差速器与直驱电机一体的后桥总成,包括直驱电机和差速器,所述直驱电机包括自外而内顺序设置的外壳、定子和转子,所述转子包括转子磁钢、转子硅钢片叠片以及所述转子轴,其特征在于,所述直驱电机的转子轴和所述差速器直接连接。本直驱电机总成的差速器和电机为一体式结构,它省去了齿轮箱和差速器外壳,结构简单紧凑,传动效率高,噪音小,车桥整体体积缩小,制造更加简单,成本更低。
