The invention provides a double-motor three-intermediate-shaft two-stage transmission wheel-side electric drive axle which comprises a left transmission mechanism and a right transmission mechanism which are symmetrically arranged and are the same in structure, and the left transmission mechanism comprises a motor, an intermediate transmission mechanism and a wheel-side transmission mechanism which are sequentially connected. The middle transmission mechanism comprises a first-stage driving wheel, three first-stage driven wheels, three second-stage driving wheels and a second-stage driven wheel, and the first-stage driving wheels are connected with an output shaft of the motor, evenly distributed in the circumferential direction of the first-stage driving wheels and connected with the first-stage driving wheels in a meshed mode; the secondary driving wheels and the primary driven wheels are coaxially connected through the intermediate shaft, the secondary driving wheels and the primary driven wheels are in one-to-one correspondence and are in meshed connection with the secondary driven wheels, and the secondary driven wheels and the primary driving wheels are coaxial and are connected with the wheel edge transmission mechanism. The two-stage three-intermediate-shaft transmission mode is adopted, large-speed-ratio and large-torque transmission output can be guaranteed, the problems of gear shifting power interruption and gear shifting efficiency loss are solved, large-speed-ratio design can be achieved, and the power performance requirement of the whole large-tonnage mine truck type vehicle is met.
