How to repair the out-of-round Tesla original wheel hub

How to repair Tesla's original wheels out of round 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 (Jiangsu, Zhejiang and Anhui Junction), the geographical location 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.

The material development of ordinary automobile 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 the mechanical design, there is a big gap between the strength and toughness of the two different 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. How to repair Tesla's original wheel out of round? 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, integrity management"; the demand is "to satisfy all customers", a strong Research and development capabilities; 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".

Compared with steel wheels, aluminum alloy wheels have obvious advantages: low density, about 1/3 of steel wheels, which means that aluminum wheels with 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 to energy saving, emission reduction and low-carbon life.

The thermal conductivity of aluminum is higher than that of steel, so under the same conditions, the heat dissipation performance of aluminum alloy wheels is better than that of steel wheels. How to repair Tesla's original wheel out of round 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. 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. 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. As we all know, the car wheel is an important part of the car.

In order to ensure the safety of the car, it is necessary to choose a good wheel hub. When choosing aluminum alloy wheels, we need to know that their aluminum alloy wheels also have advantages and disadvantages. Aluminum alloy wheels are light in weight, good in heat dissipation and good in appearance, gradually replacing steel wheels.

The basic principle of choosing a wheel hub or wheel cover is that it must be easy to clean and not blindly pursue beauty. When washing the car, the hub or wheel cover with complex structure is very troublesome. It is good to be beautiful, simple and easy to clean. How to repair the out-of-round Tesla original wheel? Make color preparations according to the original color of the wheel, and choose different types of sandpaper for grinding according to the degree of damage. We need to repaint the car wheel.

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.
