OEM Manufacturer Chery S21 - Professional Forged Aluminum Chery Car Alloy Wheel Rims – Qingzhi

Wheel hub, also known as rim, is a barrel shaped part of the tire inner contour used to support the tire, and the center is assembled on the shaft. Common automobile wheels include steel wheels and aluminum alloy wheels. Steel wheel hub has high strength and is often used in large trucks; However, the steel wheel hub has heavy quality and single shape, which is not in line with today’s low-carbon and fashionable concept, and is gradually replaced by aluminum alloy wheel hub.
(1) Compared with steel automobile hub, aluminum alloy hub has obvious advantages: low density, about 1 / 3 of steel, which means that aluminum alloy hub with the same volume will be 2 / 3 lighter than steel hub. Statistics show that the vehicle mass can be reduced by 10% and the fuel efficiency can be improved by 6% ~ 8%. Therefore, the promotion of aluminum alloy wheels is of great significance for energy conservation, emission reduction and low-carbon life.
(2) Aluminum has high thermal conductivity, while steel has low thermal conductivity. Therefore, under the same conditions, the heat dissipation performance of aluminum alloy hub is better than that of steel hub.
(3) Fashionable and beautiful. Aluminum alloy can be age strengthened. The cast blank of aluminum alloy wheel hub without aging treatment has low strength and is easy to process and shape. The aluminum alloy wheel hub after corrosion-resistant treatment and coating coloring has various colors, exquisite and beautiful.
There are many types and structures of aluminum alloy wheels, and their requirements vary according to vehicle type and vehicle model, but both strength and precision are the most basic common requirements. According to the market research, the wheel hub should have the following properties:
1) The material, shape and size are correct and reasonable, can give full play to the function of the tire, can be interchanged with the tire, and has international universality;
2) When driving, the longitudinal and transverse runout is small, and the unbalance and moment of inertia are small;
3) On the premise of lightweight, it has sufficient strength, stiffness and dynamic stability;
4) Good separability with axle and tire;
5) Excellent durability;
6) Its manufacturing process can meet the requirements of stable product quality, low cost, multiple varieties and large-scale production.
