When people's living standards improve, buying a car is no longer just a means of transport. In the purchase of a car, there are many additional requirements. Mercedes-Benz MPV commercial vehicle models are becoming more and more popular with the increase of two-child families and the needs of enterprises and institutions for business reception, especially after the interior of the modified commercial RV, because of its distinctive appearance, gorgeous interior Rich features are more popular. In practice, some customers will ask for a larger wheel when they buy a car, but is this really good? Zhejiang Minhang Xinxiao gave you a popular science and hoped to give you a rational choice when choosing a car.

You may not notice before that almost all of the car production OEMs have three things that will not be produced: car wheels, car tires, car glass. These accessories, the main engine factory are all mining, why? Because "safe"! The concept of safety runs through all aspects of production, life, study, and work. Professional people do professional things, safety is guaranteed, and so is car production. The production of automobile wheels, automobile tires and automobile glass is a professional and serious matter, which requires very professional production technology and processing equipment, which is not available in automobile production OEMs. The automobile main engine factory, its strength is now the overall design and assembly production of the car, so even if it has strength, it will never touch the field that it is not good at.

Since the car manufacturers do not touch the field, then as a car consumer, should we be cautious when dealing with the above three aspects? Next, Otaru gives you the knowledge of the wheel hub.

According to the material, the wheel hub can be divided into steel wheels and alloy wheels. At present, aluminum alloy wheels are the main market. The alloy material wheel has light weight, small inertia resistance, high production precision, small deformation at high speed rotation, small inertia resistance, and reduced fuel consumption. At the same time, the thermal conductivity and heat dissipation of the alloy material are good, which can play a certain role in the braking system of the vehicle, the thermal attenuation of the tire and the brake system, and is beneficial to driving safety.

The production of the hub can be divided into gravity casting, forging and low-pressure precision casting. Low-pressure precision casting is the current mainstream wheel manufacturing process. It is precision casting at a low pressure of 0.1Mpa (megapascal). This casting method has good formability, clear outline, uniform density and smooth surface, which can achieve high strength. Lightweight and cost-effective. The manufacturing process of the high-end modified wheel hub is forging. The forging process is to directly extrude the whole aluminum ingot from the die by a thousand tons of press. The wheel hub is thin and light, and the strength is high, but the yield is very low, so the manufacturing cost is low. high.

  Finally, let's focus on today's theme. For a Mercedes-Benz business car, the larger wheels will have a stronger visual impact and the style will be more attractive. And many people still hang a safety effect on the big wheel on the mouth, that is, once the tire is blown, the diameter of the big rim with the low flat ratio tire will not change greatly after the gas is lacking, and the vehicle will not suddenly become serious. The deviation is a danger, then the problem is that the big rim really only has advantages and no shortcomings? Not also!

First, fuel consumption increases. The large rim has an advantage in diameter and the corresponding tread width is also larger. The advantage is that the contact area between the wheel and the road surface is increased, the grip force can be increased, and the stability of the vehicle is improved. But the price comes from the fact that the friction becomes larger and the fuel consumption will increase to some extent.

Second, the quality is not good. If you want to modify your own wheel hub, you must be careful not to mention the impact on power, appearance and handling after the modification. The larger tires require higher processing technology and technology. This is a general low-qualification wheel manufacturer. do not have. Nowadays, there are many cheap wheels on the market, especially auto parts city and online, even one or four hundred. Such a hub, if the bump is easy to break at high speed, has a great impact on safety, do you use it instead? Vehicles designed by the manufacturer, there are also requirements for the bearing capacity of the hub and the strength of the hub of different sizes. When you buy millions of Mercedes-Benz commercial RVs, you will never allow the use of your car to have a safety impact. Inferior wheels?

Finally, Xiao Yan reminds you that when we buy a Mercedes-Benz business car, we should pay attention to the safety issues. If you want to change the wheels for free, you want your friends to think twice about changing the wheels. Yeah!

For questions about the purchase of RV, you can directly call Zhejiang Xinxinxing, Xiaoyan to help you answer, Vip hotline, welcome to visit the website: http://, a variety of RVs are in hot sales.

The die casting process involves the use of a furnace, metal, die casting machine, and die.

The metal, typically a non-ferrous alloy such as aluminium or zinc, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting parts.

The castings that are created in this process can vary greatly in size and weight, ranging from a couple of ounces to 100 pounds. One common application of die-cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.

Metal housings for a variety of appliances and equipment are often die cast.

Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Most home appliances also need lightweight and firm aluminum die casting parts, like bracket, heat dissipation module or structural support. Other common die cast parts include propellers, gears, bushings, pumps, and valves.
