Description

Lightweight motor shaft

Technical Field

The present invention relates to motors, and more particularly, to a lightweight motor shaft.

Background

At present, the driving motor technology is mainly developed towards light weight. A large number of researches show that the energy loss of the automobile is in direct proportion to the mass of the automobile, and the light weight of the automobile is an important means for reducing the energy loss of the new energy automobile and improving the driving mileage. The new energy pure electric vehicle driving system usually accounts for 30% -40% of the total mass of the vehicle, and the light weight of the driving system is one of the key points of the light weight of the whole vehicle. The automobile driving motor is a core driving part of a new energy automobile, and needs to meet the dynamic requirements of all working conditions of the automobile in a limited arrangement space, so that a high-efficiency, safe and reliable high-power-density motor is designed in a smaller space, and the key problems of realizing motor lightweight, reducing automobile energy loss and needing to be solved are solved.

The motor shaft is designed in a light weight mode, the rigidity of the transmission shaft can be kept, the quality of the transmission shaft can be reduced, and the problem of energy loss of a new energy automobile is solved.

In order to reduce the weight of a vehicle body, a hollow shaft is adopted in a driving motor part of a new energy vehicle on the market, but the hollow shaft needs to bear large torque, so that the strength of the new energy vehicle needs to meet the requirement firstly when the new energy vehicle is manufactured to be light.

Therefore, a new solution is needed to solve this problem.
