A sunken wheel-side motor drive axle is disclosed. The sunken wheel-side motor drive axle comprises an axle beam assembly (8), and further comprises two drive motor assemblies, two reducer assemblies and two hub assemblies, and the two drive motor assemblies, two reducer assemblies and two hub assemblies are respectively disposed at left and right ends of the axle beam assembly (8); the drive motor assemblies are symmetrically disposed at a bottom of the left and right ends of the axle beam assembly (8) respectively; and the drive motor assemblies transmit power to the reducer assemblies, and the reducer assemblies drive the hub assemblies to rotate. In the wheel-side electric drive axle, the drive motors are disposed at the bottom of the axle beam assembly (8), thereby reducing the occupied space, increasing the aisle width of new energy commercial bus, and improving the comfort of passengers; moreover, the transmission speed ratio is increased through the three-stage speed reducing transmission, thereby reducing the requirement for the output torque of the drive motor while ensuring the same wheel end drive torque, and also effectively reducing the size of the drive motor.
