What is the size of Changan wheel hub? It is a high-tech enterprise in my country that focuses on the research and development, design, production and sales of aluminum alloy wheels, and an enterprise in the export base 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.
Clean the car wheels and check for any scratches, depth of scratches, damage to the wheels. For example, a car wheel with cracks, deformation or complete fracture on the surface cannot be repaired. After washing the hubs, dry them with a towel.
After cleaning, pay attention to cleaning the hub with oil wax paper. First remove the tire, release the tire pressure, squeeze the tire into a flat state, and then directly remove the rim on the tire puller (this can avoid the tire from entering water during construction). If the wheel hub is not damaged or deformed, it can be repaired. After cleaning the wheel hub , dry with a towel, and pay attention to cleaning the hub with wax paper after cleaning. 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". 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. What is the size of Changan wheel hub? The company was 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.
In fact, it's not necessarily because aluminum alloys are much weaker 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 maintenance of the car hub is just like the maintenance of the car. Many household cleaners and detergents commonly used in the market have too much impact on the surface of the hub due to alkalinity or acidity, and will produce a chemical reaction on the surface of the hub, making it tarnish and affecting the surface of the hub. Exterior. Therefore, it should be used with care.
You can choose some neutral soapy water to wash. In order not to damage the protective layer of the hub surface, paint polish or other abrasive materials must not be used on the hub. When the alloy protective paint is damaged, such as scratches by hard objects during driving, repair and repaint the alloy wheels at a professional maintenance station as soon as possible.
When the temperature of the hub is high, let it cool naturally before cleaning, and do not wash it with cold water. Otherwise, the aluminum alloy wheel hub will be damaged, and even the brake disc will be deformed, which will affect the braking effect. In addition, cleaning the aluminum alloy wheel with a high-temperature cleaning agent will cause a chemical reaction on the surface of the wheel, which will lose its luster and affect the appearance.
When the asphalt on the wheel hub is difficult to remove, if the general cleaning agent does not help, try to use a brush to remove it, but do not use a hard brush, especially an iron brush, so as not to damage the surface of the wheel hub. What is the size of the Changan wheel? The material development of the ordinary car wheel 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%. Therefore, in mechanical design, the strength of two different materials There is a large gap in toughness. 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.
