The compressive strength of aluminum alloy wheels is quite high, and the compressive capacity of ordinary household wheels is more than 20 tons. The use of such wheels in actual trucks can meet the requirements, but the brittleness of aluminum alloy materials is poor, that is, when the compression limit is 20 tons, the elastic deformation space before fracture is very small, as long as the standard basic fracture moment is exceeded. Therefore, off-road vehicles often do not use aluminum alloy wheels. Occasionally flying will easily cause the wheel to break, but again, the possibility of such a situation is very small for off-road domestic vehicles. The wheels of this material can meet various paved and normal non-paved roads. road commuting.
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. In order to enhance the external beauty of aluminum alloy wheels and protect the environment, the traditional painting process and electroplating process will be gradually reduced and replaced by water-based powder coating technology.
After polishing and spraying transparent powder, the appearance of bright metal hub can replace electroplating. Coated wheels are not only colorful, but also environmentally friendly and exquisite, which can meet your needs to a large extent. Brushing is a means of surface treatment, through the grinding of products to form lines on the surface of the workpiece, so as to play a decorative role, because this tire seems to have two colors, and the surface is shiny, which is also one of the important factors for car owners to choose wheel brushing one.
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 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. 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. Under the premise of the same weight, the aluminum alloy wheels have stronger impact resistance, while the steel wheels are more flexible. The impact force that can deform a steel wheel may not deform an aluminum alloy wheel, because aluminum alloy wheels are thicker.
However, when the impact force is large enough to a certain extent, the aluminum alloy wheel may break directly, while the steel wheel will only deform more seriously. Under the premise of ensuring the strength, the lighter the hub, the better, the more sensitive the suspension response, the less effort the hub rotates, the better the acceleration, and the better the theoretical fuel consumption. Aluminum alloy wheels are generally considered to be lighter.
