  • Publication number: 20250116324
    Abstract: A power shaft structure of an electric drive assembly is disclosed. The power shaft structure comprises a main shaft, a right end of the main shaft is located inside a motor and fixedly connected to a rotor of the motor, and a left end of the main shaft is located inside a reducer and fixedly connected to a driving gear and a parking gear of the reducer. At least one side of the driving gear is provided with an axially extending flange, and at least one side of the parking gear is provided with an axially extending flange. A bushing is provided between an inner hole of one flange at one side of the driving gear and the main shaft as well as between an inner hole of one flange at one side of the parking gear and the main shaft for radial positioning of the driving gear and the parking gear, so that the driving gear, the parking gear, and the main shaft are on the same axis, thereby improving the stability and NVH performance of the electric drive assembly.
