A wheel hub is a cylindrical metal part in a car tire that uses the shaft as the center to support the tire. In layman's terms, it is the part where the axle is installed in the center of the wheel. It is an important connection between the brake drum (brake disc), the wheel disc and the axle shaft. Parts. The wheels on the market can be divided into steel wheels and alloy wheels according to the material, and each has its own advantages and disadvantages. The main advantages of steel wheels are simple manufacturing process, relatively low cost, and strong resistance to metal fatigue. Alloy wheels can just make up for this problem. They have lighter weight, low inertial resistance, high manufacturing precision, small deformation during high-speed rotation, and low inertial resistance, which is beneficial to improve the straight-line driving performance of the car and reduce the rolling resistance of the tires. Reduce fuel consumption. The alloy wheels of the original cars on the market are mainly made of aluminum alloy, and magnesium wheels may become a new trend in the future.

Automobile wheels are an important part of auto parts. With the growth of China's auto parts industry, the wheel industry has gradually developed and grown. Statistics show that since 2010, the macroeconomic policy focusing on stimulating domestic demand has provided the foundation and guarantee for the steady development of the automotive industry. According to the "2013-2018 China Automobile Wheel Market Investment Prospect Analysis Report" released by China Business Intelligence Network, in 2012, automobile production and sales both exceeded 19 million, and production and sales reached a new high. my country continues to be the world's largest automobile production and consumer country. status. In the first half of 2013, both automobile production and sales exceeded 10 million, with a year-on-year growth of more than 10%, showing a steady growth overall.

In the long run, the rapid growth of China's GDP provides a broad demand space for the automobile industry, and the demand for automobile wheels will increase with the growth of automobile sales. In the next few years, China's automobile sales are expected to continue to grow steadily, providing development opportunities for the automobile wheel industry.
