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 wheel hub of the car frequently, and pay attention to whether there are early warning signs of wear, including friction noise when turning or suspension combination wheel turning. Abnormal deceleration. 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. Based on the principles of technological innovation and independent research and development, the OEM company of Mercedes-Benz Aluminum Alloy Wheels 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", a strong R & D 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". 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 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. Mercedes-Benz aluminum alloy wheels is an OEM company 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.
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. 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. Slight deformations are not visible to the naked eye, and deformations are not visible inside car wheels. At this time, when driving fast, the steering wheel shakes, indicating that the wheel hub of the car may be deformed, and it is time to balance it.
Hub flanges are divided into inner flanges and outer flanges. The outer flange is visible, but the inner bridge is not. However, when getting out of the car at high speed, you can pay attention to whether there is vibration in the steering wheel or whether the tire is leaking.
If there is one of these two cases, it must be deformed. If the hub of a car is cracked in a big pit, it will definitely be deformed. At this time, it is necessary to repair the deformation when repairing the crack.
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.
