The invention provides a dual-motor gear reduction drive axle assembly with a hub reduction mechanism. The dual-motor gear reduction drive axle assembly comprises a dual-drive motor, an axle housing assembly, a brake module, a gear reduction module, a differential mechanism module and a motor control unit used for controlling the working state of the dual-drive motor. The dual-drive motor comprises a main drive motor and an auxiliary drive motor, and the main drive motor and the auxiliary drive motor are arranged on the front side and the rear side of the axle housing assembly respectively. Power input by the motor is distributed to the two half shafts through the differential mechanism and finally transmitted to wheels through the hub reduction gear. The double-motor two-gear cylindrical gear speed reducing mechanism comprises a gear shifting mechanism, and two-gear speed reducing and gear shifting operation can be achieved. The differential mechanism module comprises a differential mechanism and a vehicle s
