Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a method for preparing a drive motor shaft of a new energy vehicle, which solves the problem that the strength of the drive motor shaft of an existing new energy vehicle still cannot meet the demand, the strength is low, and the drive motor shaft cannot be realized from the motor shaft. The raw material processing and forming can be improved, so that the strength of the motor shaft can be further improved, and the occurrence of gaps or dislocations between raw materials cannot be well avoided, and the mechanical strength of the motor shaft cannot be effectively improved, thus limiting new energy. The problem of the use range of the automobile drive motor shaft
