In fact, this is not necessarily because the strength of aluminum alloy is much lower 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 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. Generally, the wheel hub sizes calibrated by auto wheel hub 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.
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. How much is Chery aluminum alloy wheel hub A slight deformation cannot be seen with the naked eye, and no deformation can be seen inside the wheel hub of the car.
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. 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. When the surface of the car hub is worn by hard objects, the air can directly contact the aluminum, oxidize at the damaged part first, and then gradually spread to the surrounding area for oxidation in the future.
Oxidation of car wheels is usually caused by corrosive chemical products. Remove dust and debris, get clean alloy wheels from the store, and avoid acidic detergents. Mix the right amount of water and detergent in a bucket.
Sponge soaked in detergent and bucket. Squeeze the sponge bucket to avoid wasting detergent. Wipe the wheels with a sponge.
The density of steel is significantly higher than that of aluminum alloy building materials, which is why aluminum alloys have been used for the lightweight of automobile chassis in my country; automobile wheels are "unsprung 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.
For all types of off-road vehicles and heavy trucks, the original intention of using steel car wheels is to ensure driving safety in harsh environments, because although the deformation limit of these car wheels is very low, the deformation caused The breaking limit is relatively high. That is to say, the deformation of the steel automobile wheel hub is very serious. As long as it does not break after deformation, it can be driven barely, while the off-road vehicle is mainly driven on unpaved roads. With the ups and downs of the road surface and the interaction of various foreign objects, the wheel hub of the car is easily deformed.
