How to repair the out-of-roundness of Mercedes-Benz aluminum alloy wheels

How to repair the out-of-roundness of Mercedes-Benz aluminum alloy wheels is a high-tech enterprise in my country that focuses on the research and development, design, production and sales of aluminum alloy wheels, and an export base of auto parts in my country. It is located in Guangde Economic Development Zone, Anhui (the junction of Jiangsu, Zhejiang and Anhui) Office), the geographical position is superior and the transportation is convenient. The company covers an area of ​​120 mu, with a registered capital of 118 million yuan, total assets of nearly 180 million yuan, and more than 300 employees. It has 11 authorized inventions, 18 utility model patents, and 40 design patents. The company's stock was listed on the New Third Board on August 12, 2016. The stock code is 838269. The stock is referred to as "Technology". Special new "small and medium-sized enterprises, provincial high-tech cultivation enterprises.

First of all, a big advantage of aluminum alloy wheels compared to iron wheels is heat dissipation. First of all, the heat transfer coefficient of aluminum alloy will be about 3 times that of ordinary iron hub. Aluminum alloy wheels quickly transfer heat to the air, which undoubtedly increases the safety factor of the vehicle.

Secondly, the weight of the aluminum alloy wheel will be about 2 kg lighter than the iron wheel, so the 4 aluminum alloy tires will be about 8 kg lighter than the iron tire. To a large extent, it helps the car's handling, cornering or cornering more nimbly. It can also reduce fuel consumption to a certain extent.

How to repair the out-of-roundness of Mercedes-Benz aluminum alloy wheels? Based on the principle of technological innovation and independent research and development, the company has accumulated many years of production experience, and always adheres to the marketing purpose of "customer first, honest management"; the demand is "to satisfy all customers", strong research and development Ability; the company has a complete and scientific quality management system. The company's integrity, strength and product quality have been recognized by the industry. Taking quality as the core, adhering to the business philosophy of "internationalization, branding and scale", it is committed to "continuous improvement, pursuit of high-quality products, improvement of service quality, and satisfaction client needs". Ordinary aluminum alloy wheels are light in weight and fast in speed.

The moment of inertia of aluminum alloy wheels is much smaller than that of steel wheels. Therefore, the installation of aluminum alloy wheels can make the car more sensitive in terms of acceleration, turning and braking, and the lightweight wheels can make the car speed up faster. In addition to excellent performance on flat roads, lightweight wheels can also improve comfort on bumpy roads.

The cooling effect is better. Aluminum alloy has high strength, narrow spokes, and easy styling, which can leave a larger ventilation space, accommodate larger brake calipers and brake discs, and reduce temperature more effectively. The company was founded in 2011. After more than seven years of development and operation, the company has become a large-scale enterprise in the domestic aluminum alloy wheel industry with product serialization, large-scale production and brand management.

The density of steel is significantly higher than that of aluminum alloy building materials, which is why aluminum alloys have been used for the lightweight of automobile chassis in my country; automobile wheels are "unsprung parts". If the unsprung mass cost is too large, it will inevitably affect the work performance, handling performance and actual fuel consumption. Just like a car hub, the weight loss of the hub is a direct result of the controlled torque output of the engine; because the powertrain transmitted to the wheel via the half shaft needs to be able to overcome the priority thing is the mass of the wheel (weight/drag during operation) , so the power at the hub of the car needs to be synchronized and can be lowered.

We all know that less unsprung weight leads to better car performance, better acceleration and braking, and better fuel efficiency. The hollow design greatly reduces the weight of the car hub, and the aluminum alloy also provides sufficient strength for the spokes to support the rim. This is why many car owners want to replace forged wheels.

Because the forged wheels are not only good quality, but also light weight. Of course, the hollow design saves the aluminum alloy material used in the manufacture of the wheel hub, reduces the production cost of the wheel hub manufacturer, naturally reduces the cost, and consumers also enjoy benefits. Aluminum alloy wheels are light in weight (about 2kg less than aluminum or steel wheels of the same specification), high manufacturing precision, small deformation during high-speed rotation, and anti-inertia.

This is conducive to improving the straight-line driving performance of the vehicle, reducing the rolling resistance of the tire, thereby reducing fuel consumption, reducing the weight and weight of the vehicle; the heat dissipation is good, and the heat of the brake can be released in time to avoid the decline of brake heat dissipation and affect driving safety. Aluminum alloy is relatively brittle, prone to small cracks, not easy to be found, not as strong as steel, may have sand holes during casting, tubeless tires are easy to run flat, and the price is relatively high. How to repair the out-of-roundness of Mercedes-Benz aluminum alloy wheels When the temperature of the car hub is high, it should be allowed to cool naturally before cleaning.

Do not wash it with cold water, otherwise it will damage the aluminum alloy wheel hub, and even deform the brake disc, which will affect the braking effect. In addition, cleaning the aluminum alloy wheel with a high-temperature cleaning agent will cause a chemical reaction on the surface of the car wheel, which will lose its luster and affect the appearance. If the hub of the car is bent, broken or severely corroded, it should be replaced in time.

If damaged car wheels are not replaced, the tires are likely to slip off the car wheels, and the car may even lose control. But if it's just scratches, it's not a big problem.
