How to repair the roundness of BMW spinning wheel hub

How to fix BMW spinning wheel out of round When the vehicle is moving forward, it will press down a hard and sharp object, which is higher than the distance between the outer edge of the car wheel hub and the ground, and is located on the outer edge of the tire. When the tire was pressed against the object, the sharp corner of the object just hit the outer edge of the tire, piercing the fragile outer edge of the tire (this would explain the radial fracture of the tire). After a tire blows out, it immediately loses its cushioning ability.

A hard object hit the hub directly, causing the hub to break near the edge of the valve (this would explain the defect in the edge of the hub). It then causes the entire hub to break. Or when the hub encounters a large pit, it will pass quickly, exceeding the bearing range of the hub, resulting in fracture.

Adhering to the principle of "technical innovation, quality first, customer first", we are actively exploring new markets. The company now integrates production, scientific research and sales. With the continuous expansion of domestic and foreign markets, the company will expand its production capacity in a timely manner to meet the diverse needs of customers. We can provide services according to customer requirements for product style, structure and function. Adhere to the spirit of pioneering and enterprising, hard work and enterprising, introduce high-tech talents at home and abroad, accumulate years of industry experience, have fully automated, high-tech, high-energy-saving technologies, and introduce international management mechanisms, a management team composed of experts, and research and development, production, management team.

The green and milky white of car wheels are two contrasting colors, and the red of taillights is a good choice for red and black; so men try to choose black, because black represents stability and fierceness without losing the true color of tires. If you want to keep the original color for a long time, you should choose the change of painting color, it is recommended to go to a reputable modification shop. It's not as simple as we thought.

First of all, the surface of the car hub is leveled and repaired, then cleaned and painted, then dried at high temperature, and installed after 5 days. Be careful not to touch sharp and hard objects when driving, and remind workers not to scratch when washing the car. The density of steel is significantly higher than that of aluminum alloy building materials, which is why aluminum alloy has been used for lightweight automobile chassis in my country; automobile wheels are "non-sprung 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. The company takes "innovation, energy saving, firmness and safety" as its quality premise.

Adhere to the development concept of "beyond lightweight and serve the world". To make the impossible possible, to create extraordinary qualities. Get higher returns with less investment.

In fact, it is not necessarily because aluminum alloy is much weaker than steel. In order to ensure strength, the volume of aluminum alloy wheels is very large. So, in general, traditional alloy wheels don't have to be lighter.

Even many spare tires have steel rims, which are lighter than aluminum rims (full size). The real weight advantage is those forged wheels. Because the forging process improves the strength, the volume can be reduced, reflecting the weight advantage.

If your spare tire is a full-size steel wheel, you can check whether it is an aluminum alloy wheel or a steel wheel. The company always adheres to independent research and development, technological innovation, adheres to the business philosophy of product quality and high quality, and has perfect quality conditions and testing capabilities. The strict control and continuous improvement of the product processing process provide customers with a good guarantee of high-quality and reliable products.

Based on the enterprise spirit of "integrity, pragmatism, innovation and win-win", the company is willing to provide customers with high-quality products and services. The company has a high-quality workforce and a strong management team, and has the ability to build an advanced enterprise with research and development capabilities. Prepare the color according to the original color of the rim, and choose different types of sandpaper for grinding according to the degree of damage. We need to repaint the car rim.

But before painting, we tried to use waste newspapers to isolate the edge of the wheel hub to prevent the spray paint from splashing on the tires. Put it in the equipment at 100-120℃ to dry for 60 minutes, then grind it again to a matte finish. If it still feels a little hairy, you can continue to smooth it with sandpaper.

Cover the rim with a universal shielding film, wipe the surface of the rim with a degreaser, dry it with equipment, and wipe the surface dust with a dustproof cloth. How to repair the out-of-roundness of BMW spinning wheels The material development of ordinary car wheels is not ordinary pig iron, but steel with a carbon content of 2.0% or less; but the proportion of pig iron is as high as 2.0% to 4.5%, so in mechanical design, the two are different. There is a large gap in the strength and toughness of materials. However, even steel is not very strong.

For example, body A-pillars made of hot-formed steel with a yield strength of up to 1,500 MPa may still bend in a crash. Therefore, the compression ability of the steel wheel hub is relatively weak, that is to say, it is relatively simple and easy to deform.
