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.
