Welded high-strength wheel

Abstract

A welded high-strength wheel is composed of a rim and a spoke, and is characterized in that a groove bottom of the rim forms an included angle of 1 degree relative to the horizontal line, a skirt of the spoke forms an included angle of 1 degree relative to the horizontal line, and the groove bottom of the rim and the skirt of the spoke are welded together.

Description

technical field [0001] The invention relates to a welded high-strength wheel. Background technique [0002] As one of the most important safety components of passenger vehicles, wheels are not only directly related to the safety of drivers and passengers of passenger vehicles, but also directly affect the emissions of passenger vehicles. Studies have shown that, on the premise of meeting the performance requirements, for every 10% reduction in wheel mass, the average vehicle fuel consumption per 100 kilometers can be reduced by 10-13ml (0.09 yuan) at an average speed of 90-120km / h. In recent years, Japanese cars, Korean cars and French cars have paid more and more attention to the weight of wheels, and are constantly pursuing light weight while pursuing structural optimization and research on high-strength materials. [0003] The original spoke and rim fit is a cylindrical fit. During the manufacturing process of the spokes, due to mold wear and material springback, the spo...

AI Technical Summary

Problems solved by technology

[0003] The original spoke and rim fit is a cylindrical fit. During the manufacturing process of the spokes, due to mold wear and material springback, the spokes and rims are not tightly fitted during the assembly process, and the fatigue durability test effect is not good.
