The hub (Car Rim) is the part where the axle is installed in the center of the wheel, which is often referred to as the "rim" or "steel ring". The wheel hub is easily stained with dirt. If it is not cleaned for a long time, it may be corroded and deformed, resulting in a safety hazard. Therefore, special attention should be paid to the maintenance of the wheel hub.
Due to different language habits, many people have different names for the wheel hub, such as "wheel rim", and many friends in the south call it "tire bell" or "car bell", don't say it to you" When you say "car bell", you will misunderstand that it is "car bell".

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. According to the "2013-2017 China Automobile Wheel Industry Market Prospect and Investment Strategic Planning Analysis Report" data show that since 2010, the macroeconomic policy focusing on stimulating domestic demand has provided the foundation and guarantee for the steady development of the automobile industry. Judging from the trend of the automobile market in 2010, the impact of macroeconomic policies on the automobile market continued throughout the year. The annual automobile production and sales reached 18.2647 million and 18.0619 million respectively. country status. In 2011, the economy continued to maintain stable growth, and the production and sales of automobiles are expected to continue to increase significantly; 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 opportunities for the development of the automobile wheel industry.
China's low ownership rate and increasing purchasing power determine that China is still in a period of rapid automobile popularization. It is expected that the annual production and sales scale of China's automobiles will reach 50 million in the future. The corresponding domestic OEM and AM market sizes of the wheel industry will be respectively 39 billion yuan and 9 billion yuan. With the continuous improvement of the international competitiveness of Chinese wheel companies, the future wheel export market size is expected to exceed 13 billion yuan. Benefiting from the continuous and rapid growth of domestic new car sales, the continuous improvement of car ownership, and the improvement of the international competitiveness of Chinese wheel companies, it is expected that the future market size of the wheel industry is expected to be close to 60 billion yuan, and it will remain relatively fast in the next 3-5 years. developing.
Velg yang ada di pasaran dapat dibagi menjadi velg baja dan velg alloy menurut bahannya, dan masing-masing memiliki kelebihan dan kekurangan.
The main advantage of steel wheels is that the manufacturing process is simple (generally using casting process, for example, aluminum alloy wheels are generally produced by low-pressure casting process), the cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and cheap. solid. However, the disadvantages of steel wheel hubs are relatively prominent, including ugly appearance (it can be said that there is no appearance at all), heavy weight (the same wheel hub steel material is much heavier than aluminum alloy material), large inertial resistance, and poor heat dissipation. And very easy to rust. Alloy wheel hubs can just make up for this problem, light weight, low inertia resistance, high manufacturing precision, small deformation during high-speed rotation, low inertia resistance, which is conducive to improving the straight-line driving performance of the car and reducing the rolling resistance of tires, thereby Reduced fuel consumption. The thermal conductivity of the alloy material is about three times that of steel, and the heat dissipation is good, which can play a certain role in the thermal attenuation of the vehicle's braking system, tires and braking system. The alloy wheels of the original cars on the market are mainly made of aluminum alloy. Of course, many modified wheels will choose chromium, titanium and other elements as the basic materials in order to meet certain special requirements and improve the vision. However, compared with steel wheels, the price of alloy wheels is much more expensive, so often in many low-end and mid-level original cars, steel wheels will appear on low-end models, while alloy wheels are high-end models. Standard on the model.
