AI Technical Summary
Technical Problem
The existing drive axle motor structure is not suitable for small vehicles, as it has a large axial space and is difficult to install.
Method used
The axle housing is shared by the left and right drive shafts. The stators of the left and right motors are fixedly connected to the inner wall of the axle housing. The left and right reducers are connected to the axle housing through support sleeves, which shortens the axial distance. Heat dissipation channels and shock absorption mechanisms are set inside the axle housing.
Benefits of technology
The drive axle motor has a compact structure, making it suitable for small vehicles. It has a small axial space and good heat dissipation and shock absorption performance.
