The invention provides a dual-motor electric drive axle assembly with a hub reduction gear. The dual-motor electric drive axle assembly comprises a first drive motor M1 and a second drive motor M2 which are distributed on the two sides of an axle. The first driving motor M1, the first gear transmission speed reduction module, the second gear transmission speed reduction module and the third gear transmission speed reduction module are connected in sequence, and the power output of the first driving motor M1 transmits power to the third gear transmission speed reduction module through the first gear transmission speed reduction module and the second gear transmission speed reduction module in sequence; and the power output of the second driving motor M2 transmits the power to the third gear transmission speed reduction module through the fourth gear transmission speed reduction module and the fifth gear transmission speed reduction module in sequence to be converged with the power of the first driving motor M1. Driving force is coupled differently at different vehicle speeds and under different loads, real-time power distribution is achieved, and the power performance of the whole vehicle is improved; single-motor driving is achieved under common working conditions, the motor load rate is increased, and the whole vehicle economy is improved.
