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 "survival by quality, market by reputation, development by science and technology, and efficiency by management" as its business purpose. In order to ensure that every wheel hub can do better, the company has built a strict quality monitoring and testing system. , Products have passed TS16949 quality system certification. The products include cast wheels and forged wheels. The annual output of casting wheels reaches about 1.1 million pieces, and the annual output of forged wheels reaches about 18,000 pieces. The products not only cover nearly 30 provinces, municipalities and autonomous regions in China, but also are exported to the United States, Russia, Southeast Asia, and the Middle East. , Japan, Singapore, Iraq and other dozens of regions. In order to meet the market demand, the company is still constantly reforming and innovating, improving management level, improving product quality, giving full play to the company's technical advantages, brand advantages, talent advantages and customer advantages in the industry, and striving to build the company into a competitive and competitive company in the industry. An enterprise with influence and development potential.
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.
Over the years, all employees of the company have been determined to forge ahead, and the technology and equipment have been continuously improved, forming a full-coverage aluminum alloy wheel forging business. In order to adapt to the development of the market, a group of technical and management talents have been trained, and a good market reputation has been formed. It will develop in the direction of "higher and farther" and better serve the majority of car owners and the society. 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.
The company has a management team with excellent technology and rich management experience, adheres to the corporate philosophy of "customer first", builds core competitiveness, gives full play to comprehensive advantages, strives for progress in stability, and creates an excellent brand in the alloy wheel industry, so that strong quality and fashion peers. 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. If the aluminum alloy wheel is broken, in order to save costs, you still go to some unprofessional places for repairs, then you are very wrong, so the repaired wheels are not guaranteed. In fact, many places are reworked by the original factory process, and the airtight test, grinding, painting and other processes can be reworked.
If you're concerned about safety, the hubs are also cast from an aluminum alloy solution during the casting process. Similarly, the welding is carried out by means of internal and external welding, and the same aluminum alloy material is used, so there is no need to worry about quality problems. Which Volvo wheel manufacturer is good? Car wheels play an important role in improving the appearance, but when choosing wheels, every detail must be meticulous.
The parameters of the hub will affect the use of the hub and the vehicle. If the PCD value is incorrect, it may not install properly. The ET value will not only affect installation and use, but also affect future upgrades and modifications.
When reinstalling the car hub, attention should be paid to the size of the hole. If this size is smaller than the original size, it cannot be installed naturally. However, if it is larger than the original size and no comparison measures are taken, the concentricity of the vehicle will be different when driving, resulting in abnormal noise and vibration of the vehicle, which will directly affect the vehicle in severe cases.
