The invention provides a modularized electric drive axle integrated with electric wheels, which comprises an axle frame, electric wheels, a battery system, a high-voltage distribution box, a motor integrated driver (MCU), an axle comprehensive controller, a hydraulic system, a cooling system, a suspension system, a steering system and the like. Hub motors, brakes, speed reducers and wheels are integrated on the electric wheels. High-voltage electric energy of the modularized electric drive axle flows out through a battery system and is conveyed to a motor integrated driver through a high-voltage distribution box, and the motor integrated driver controls output of an electric wheel hub motor, a hydraulic system oil pump motor, a steering system steering motor and the like. The axle comprehensive controller controls drive of hub motors on the two sides of the axle, axle braking, steering, suspension and cooling in a coordinated mode, and the purpose of reliable running of the vehicle is achieved. The modularized electric drive axle is also an independent whole and has high adaptability, the assembly of the electric drive whole vehicle can be simplified into the combination of the modularized axle, and the improvement of the assembly and maintenance efficiency of the whole vehicle is facilitated.
