The hub, that is, the inner shape of the tire, is used to support the barrel of the tire, and the center is assembled on the hub axle. Common car wheels include steel wheels and aluminum alloy wheels. Steel wheels have high strength and are often used in large trucks;

However, steel wheels are heavy and have a single shape, which does not conform to today's low-carbon and fashionable concepts, and is gradually replaced by aluminum alloy wheels.

 Advantages of aluminum alloy

(1) Compared with steel car wheels, the advantages of aluminum alloy wheels are obvious: the density is small, about 1/3 of that of steel, which means that aluminum alloy wheels of the same volume will be 2/3 lighter than steel wheels. Statistics show that if the vehicle quality is reduced by 10%, the fuel efficiency can be increased by 6% to 8%. Therefore, the promotion of aluminum alloy wheels is of great significance for energy saving and low-carbon life.

(2) The thermal conductivity of aluminum is high, while the thermal conductivity of steel is low, so under the same conditions, the heat dissipation performance of aluminum alloy wheels is better than that of steel wheels.

(3) Fashionable and beautiful. Aluminum alloy can be strengthened by aging, and the aluminum alloy wheel plate without aging treatment has low strength and is easy to process, and the aluminum alloy wheel hub that has undergone corrosion-resistant treatment and coloring is exquisite in color.

Structural Analysis of Automobile Aluminum Alloy Wheels

In order to meet the needs of the use function and the market, the structure of aluminum alloy wheels has various structural designs such as integral type and multi-piece combination; there are designs such as wide spokes, narrow spokes, multiple spokes, and few spokes. For safety reasons, the appearance and structural design of aluminum alloy wheels must be based on safety and functional use requirements. For ordinary passenger cars, the overall aluminum alloy wheels are sufficient to meet their performance requirements.

Performance requirements of aluminum alloy wheels for automobiles There are many types and structures of aluminum alloy wheels, and the requirements vary with vehicle types and models. However, strength and accuracy are the most basic requirements. According to market research, the hub should have the following properties:

1) The material, shape, and size are correct and reasonable, which can give full play to the functions of the tire, are interchangeable with the tire, and have international versatility;

2) Longitudinal and lateral oscillations are small when driving, and loss and moment of inertia are small;

3) Have sufficient weight, stiffness and dynamic stability under the premise of weight reduction;

4) Good separation from axles and tires;

5) Excellent durability;

6) The manufacturing process can meet the requirements of stable product quality, low cost, variety and large-scale production.
