Description

technical field [0001] The invention belongs to the field of new energy vehicle manufacturing, and relates to a motor shell of a gasoline-electric hybrid four-wheel vehicle and a preparation process thereof. Background technique [0002] With the increasing scarcity of energy and the aggravation of environmental pollution, the oil-electric hybrid four-wheel vehicle with energy-saving and environmental protection effects has gradually become the main direction for the development of small cars in the future. As the heart of new energy vehicles, the motor is very important. Most of the existing motor housings are steel castings, which have many defects, such as high production energy consumption, low casting yield, heavy weight and poor corrosion resistance. defect. [0003] Magnesium alloy is the most widely used alloy in contemporary industrial engineering, with the lightest weight, high specific strength and high specific stiffness. The current price of magnesium al...
