How to repair the original wheel hub of Audi

How to repair the original Audi wheel is broken. It is a high-tech enterprise in my country that focuses on the research and development, design, production and sales of aluminum alloy wheels. It is located in Guangde Economic Development Zone, Anhui (the junction of Jiangsu, Zhejiang and Anhui) ), strategic location and convenient transportation. 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.

Many people think that as long as the car hub does not touch the outer metal plate when installing, in fact, when disassembling the wheel, if you look carefully at the structure inside, it is easy to get stuck in many places, especially after the car is started, on rough roads, the shock absorber Instantly compresses. Therefore, make good use of large wheels. You must drive beautifully.

Also pay attention to the width of the rim. Second, the brake calipers snap onto the rim. Because cars these days often use large calipers for safety, a 4lb caliper is much bigger than a can.

Underbiased and poorly designed wheels often get stuck on the brake calipers. Fortunately, it's easy to spot in this case. 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 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". In fact, it's not necessarily because aluminum alloys are 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 original Audi wheel repair 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.

When the vehicle is moving forward, it presses down on a hard, sharp object that is higher than the distance between the outer edge of the car's 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.

On average, each aluminum alloy wheel is 2 kg lighter than a steel wheel of the same size, and a five-wheeled vehicle can save 10 kg. Although aluminum alloy wheels are more expensive than ordinary steel wheels, the fuel cost savings will be enough to offset the cost of driving 20,000 kilometers per car. The impact resistance, tensile strength and thermal strength of aluminum alloy wheels are higher than those of steel wheels.

This is also one of the reasons why aluminum alloy occupies an important position in my country's imitation industry and aviation industry. The precision can be as high as 0.05mm, and the balance performance is good, which is beneficial to eliminate - in addition, the general body length and steering wheel vibration. Car owners should pay attention to low obstacles on the road during daily driving, and avoid getting too close to the roadbed when parking.

In this way, it is easy to cut off the wheel hub of the car, which will affect the appearance, and the anti-rust coating will also be scraped off, which will affect the water resistance and corrosion resistance, deform the wheel hub, and affect driving. Check for scars. If the inside of the hub is not damaged, wipe around the scar with paint thinner to remove dirt.

When cleaning, in order to prevent unrelated parts from being stained with paint, tape can be pasted around the scar. Use the brush tip to apply topcoat to the damaged parts of the car hub. After drying, it shrinks slightly.

How to repair the original Audi wheel hub? According to the material, the car hub is mainly divided into steel hub and light alloy hub. In today's automobile market, steel wheels are rare, and most models use aluminum alloy wheels, that is, light alloy wheels. The aluminum alloy materials used to make aluminum wheels include A356, 6061, etc., among which A356 is widely used as cast aluminum wheels.

A356 aluminum alloy has the characteristics of small specific gravity and good corrosion resistance. It is mainly composed of aluminum, silicon, magnesium, iron, manganese, zinc, copper, titanium and other metal elements, and aluminum accounts for about 92%, which is a mature aluminum alloy material.
