Coaxial asynchronous electric drive system

A coaxial asynchronous motor drive system, comprising a speed reducer, an electric motor and a main housing, and further comprising a motor controller, wherein the electric motor and the speed reducer are connected to form a motor reducer assembly and mounted inside the main housing, and the motor controller is fixed to the main housing and connected to the motor reducer assembly;

• an input shaft and an output shaft of the speed reducer are in a line, and a speed reducer input gear is provided on a hollow motor shaft of the electric motor;
• and
• the electric motor controller controls to drive the gear on the hollow motor shaft of the electric motor to mesh with an intermediate shaft assembly to transfer an increased torque to an integral differential, and the torque is output to two sides via the integral differential, with a differential axle shaft gear spline on one side thereof for connection to a vehicle gearbox-side axle shaft, and a differential axle shaft gear spline on the other side thereof being connected to a short axle shaft which passes through a motor rotor and which is provided with a spline and retaining ring at a motor exposed end for connection to a vehicle motor-side axle shaft internal spline,
• the input shaft of the speed reducer is the hollow motor shaft, and the output shaft of the speed reducer is the differential axle shaft,
• wherein the main housing is provided with a rear suspension screw set, a front suspension screw set, a motor-side front suspension screw set, and a motor-side rear suspension screw set.
