How many kinds of wheels does a car have?

According to the surface treatment technology of wheel hub, automobile wheel hub can be generally divided into two types: baking paint and electroplating.

Baking pans are generally moderately priced and durable. Generally, the wheel hub design of ordinary models is less considered by roommates. The main requirement is good heat dissipation, and the process is basically baking paint treatment, that is, spraying first and then baking. The cost is relatively economical, and it has the characteristics of beautiful color and long retention time. Even if the vehicle has been scrapped, the color of the hub can remain unchanged.

The price difference of electroplated wheels is relatively large. Electroplated wheels are mainly divided into silver plating, water electroplating and pure electroplating. Electroplated silver and water-plated wheels generally have the characteristics of bright colors, but the retention time is relatively short, so the price is relatively cheap, which is mainly liked by many young people who pursue freshness. Pure electroplating wheel has the characteristics of long-term color retention, and it is an electroplating wheel with high quality and high price.

Steel wheels and alloy wheels

Wheels can be divided into two categories according to materials: steel wheels and alloy wheels.

The main advantages of steel wheel hub are simple manufacturing process, relatively low cost and strong metal fatigue resistance. In our daily life, it is cheap and good. However, the main disadvantages of steel wheel hub are unsightly appearance, large inertia resistance, heavy weight, poor heat dissipation and easy rusting.

Alloy wheel hub has the characteristics of light weight, low inertia resistance and high manufacturing accuracy, especially when rotating at high speed, the deformation is very small, and the inertia resistance is also very small, which is beneficial to improve the straight-line driving performance of the automobile and effectively reduce the rolling resistance of the tire, thus reducing fuel consumption to a certain extent. The thermal conductivity of alloy material is about three times that of steel, and its heat dissipation is better, which can play a good role in the thermal attenuation of vehicle braking system, tire and braking system.

At present, the alloy wheel hub of the original car on the market is mainly made of aluminum alloy. Of course, in order to meet some special requirements and related visual improvement, many modified wheels will choose some elements such as chromium and titanium as basic materials.
