Abstract

The invention relates to a shell, in particular to an automobile drive motor shell, and belongs to the field of mechanical materials. The automobile drive motor shell is made of an aluminum alloy material. The aluminum alloy material is composed of, by mass percent, 2.5%-3.2% of Mg, 1.5%-2.0% of Si, 0.5%-0.8% of Mn, 0.5%-1.5% of Cu, 0.2%-0.5% of Zr, 2%-2.5% of carbon fibers and the balance Al andinevitable impurity elements. The automobile drive motor shell is prepared from the aluminum alloy material, the compositions and the mass percent of an aluminum alloy are reasonably combined, solution treatment and artificial aging treatment are carried out, specific silanization treatment is adopted, and the obtained automobile drive motor shell can have high strength and corrosion resistance.

Description

field of invention [0001] The invention relates to a casing, in particular to an automobile driving motor casing, and belongs to the field of mechanical materials. Background technique [0002] With the development of new energy vehicles, electric vehicles or hybrid vehicles with motor drive are more and more accepted by consumers. For the motor used in electric vehicles, since the motor is generally installed in the front cabin of the car, the environment in the front cabin of the car is relatively closed, and the motor will generate a lot of heat when it is powered on. Protect the motor from the surrounding environment, so it puts forward certain requirements for its strength. However, due to factors such as its own materials and other factors, the strength of the automobile drive motor shell in the existing market cannot meet the needs of consumers, so there are still relatively large limitations in application. Contents of the invention [0003] Aiming at the above-m...
