What is the size of Audi's modified 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 my country's auto parts export base. It is located in Guangde Economic Development Zone, Anhui (the junction of Jiangsu, Zhejiang and Anhui) , strategic location and convenient transportation. 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.
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. 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 "satisfy all customers", strong research and development 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". Compared with steel wheels, aluminum alloy wheels have obvious advantages: low density, about 1/3 of steel wheels, which means that aluminum wheels with the same volume will be 2/3 lighter than steel wheels. Statistics show that if the vehicle quality is reduced by 10%, the fuel efficiency can be increased by 6% to 8%.
Therefore, the promotion of aluminum alloy wheels is of great significance to energy saving, emission reduction and low-carbon life. The thermal conductivity of aluminum is higher than that of steel, so under the same conditions, the heat dissipation performance of aluminum alloy wheels is better than that of steel wheels. 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.
Aluminum alloy wheels are more suitable for passenger cars than steel wheels. At present, their manufacturing processes can be divided into three categories. The first is casting, which is the process of choice for most car manufacturers today. Low-pressure casting is a process in which molten aluminum is filled into a mold under pressure and solidifies and crystallizes under pressure.
In the same situation, compared with gravity casting, the internal structure of low-pressure casting hub is denser and stronger. At present, low-pressure casting has become a process for producing aluminum alloy wheels, and most domestic aluminum alloy wheel manufacturers use low-pressure casting. Since car wheels can be electroplated, scratches can be repaired.
It can be repaired according to the repair method of hub vacuum plating. Moreover, with the maturity of the wheel electroplating industry, it is not limited to electroplating black and white, but can be customized according to the owner's personal preferences. However, if your original hubs were plated, the scratches can be repaired.
There are two types of plating wheels: water plating and vacuum plating. The water plating process will not produce scratches, but will corrode the hub. After the hub is corroded, it can be repaired, that is, the stripping time is long, and the water plating repair time is long.
However, the water electroplating process pollutes the environment very much, and there are few cases of water electroplating at present. On average, each aluminum alloy wheel is 2 kg lighter than a steel wheel of the same size, and a five-wheeled vehicle can save 10 kg. Although aluminum alloy wheels are more expensive than ordinary steel wheels, the fuel cost savings will be enough to offset the cost of driving 20,000 kilometers per car.
The impact resistance, tensile strength and thermal strength of aluminum alloy wheels are higher than those of steel wheels. This is also one of the reasons why aluminum alloy occupies an important position in my country's imitation industry and aviation industry. The precision can be as high as 0.05mm, and the balance performance is good, which is beneficial to eliminate - in addition, the general body length and steering wheel vibration.
When the surface of the wheel hub of a car 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 future use. 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.
