How about the strength of Audi wheel hub is a high-tech enterprise in my country focusing on the R&D, design, production and sales of aluminum alloy wheels, and an export base enterprise of auto parts in my country. It is located in Guangde Economic Development Zone, Anhui (the junction of Jiangsu, Zhejiang and Anhui). 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.
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.
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 It 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". The larger the wheel hub of the car, the lower the flat rate, that is, the thinner the tire, the clearer the feedback on the road conditions; and, when turning, because the tire contact area is large, it is not easy to deform, and the grip is better. This is also the wheel size of many sports cars and racing cars. big reason.
However, the disadvantages brought by the large wheel hub cannot be ignored, because for balance, if the wheel hub size is large, the flat rate becomes lower, and the tire wall is thinner, the ride comfort will be weakened, and the relative fuel consumption will also increase. Therefore, it is not because Pricey, it has no downsides. If you are very concerned about economy and fuel consumption, you can try to choose a smaller wheel size. The company was founded in 2011. After more than seven years of development and management, the company has become a large-scale enterprise in the domestic aluminum alloy wheel industry with product serialization, large-scale production and brand management.
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. When a car wheel is turned against the edge of the road, it is easy to damage the outer edge of the wheel. In this case, the main structure has not changed, so the safety performance of the hub is basically not affected, as long as it is repaired.
Blasting to clean dirt, sanding, putty filling, fine sanding and painting. After these repair steps, the hub is basically brand new. The wheel hub is made of aluminum alloy, and the metal has poor fatigue resistance.
After it is deformed under the action of external force, it is forced to return to its original state by external force. Even if there are tiny cracks on the surface, the metal structure here is completely different from ordinary wheels from a scientific point of view. Generally, the wheel hub sizes calibrated by car wheel manufacturers are: 15 inches, 16 inches, 17 inches, 18 inches and 19 inches.
The small ones usually come with family cars, while the big ones come with more advanced ones. For example, for a family car that is generally less than 150,000 yuan, the official selections are 15, 16, and 17; Although the high-configured large wheels look very sporty and enhance the appearance of the vehicle, they are not perfect.
It has both advantages and disadvantages. How about the strength of Audi wheels? In order to ensure the safety and reliability of the vehicle to a large extent, no matter how old the vehicle is, it is necessary to check the wheels of the car frequently, and pay attention to whether there are early warning signs of wear, including friction noise or suspension when turning. Unusual deceleration when combined wheel turns. If you hear car wheel bearing noise, first, it is important to find out where the noise is coming from.
Many moving parts may create noise, or some rotating parts may be in contact with non-rotating parts. If it is confirmed that the bearing is noisy, the bearing may be damaged and needs to be replaced. Since the failure conditions of the bearings on both sides caused by the front hub are similar, even if only one bearing is damaged, it is recommended to replace it in pairs.
