Because of thermal expansion and cold shrinkage, it is okay to keep the tire pressure of a car at 2.3 bar or even to 2.5 bar in winter, but the standard tire pressure specified by each car is different, so the specific requirements depend on the car's user manual, but the tire pressure in winter is 0.1 to 0.2 bar higher than the normal setting. The tire pressure of the car must be maintained withi...
Sports car tires are thinner because they can have a stronger grip. When the power output of the vehicle increases, the grip also needs to increase, otherwise it is difficult to cope with the output torque.If you want the grip of the tire to become stronger, you can widen the tire, but this will increase the fuel consumption of the vehicle. Sports car tires generally do not use a way to widen the ...
The structure of the automobile rim is simple and can be divided into two parts: 1.Spokes 2.rims.To be precise, the spokes of almost all automobile wheels are currently hollow. The main reasons why they are all hollow designs are： 1.Heat dissipation requirements: If the car is driving for a long time, it will make the wheels of the car very hot; in addition, the braking system will generate a lot ...
There are many kinds of wheels according to the diameter, and there are also many kinds according to the width.Then, many models can be divided into different diameters, different widths, and different materials.Some car owners think that the original tires are not advanced enough and want to upgrade. They often widen, reduce the flat ratio, increase the diameter, and change the material. At this ...
As the heavyweight component of a car, the wheel rim of a car is also very important for maintenance. If there is no proper maintenance, the car will have certain safety risks. If it is slightly smaller, it may cause the car to stop on the road and fail to start. If it is serious, it may also be dangerous.Therefore, maintenance is a very important thing. The maintenance method is mainly based on t...
Because aluminum alloy wheels have the following four characteristics, many cars currently use aluminum alloy wheels： 1.Driving comfort has been improved. Because aluminum alloy wheels have the metal characteristics of absorbing vibration and rebound, they have high dimensional accuracy after being processed by CNC machine tools.It's really round.Partial swing and small beating.The balance is very...
Some people increase the wheel rim in order to improve the performance of the car. In the case of the same tire diameter, the large wheel rim should be matched with the wide tire. The lateral swing of the car is small and the stability is improved, but the flatter the tire, the thinner its thickness, the worse the shock absorption performance, and the greater the sacrifice of comfort. The complex ...
The rim is the support inside the tire.The tire itself is very soft.The internal contour of the tire supports the barrel shape of the tire.The parts mounted on the shaft are called rims. ”Multi-layer environmental protection ion technology" electroplating wheels use powder spraying technology and magnetic control vacuum coating technology.Production technology has replaced the traditional high-pol...
The et value of the wheel rim is also called the et offset value, and the et value is the offset value, which is the offset.In fact, it refers to the degree of deviation between the rim installation interface and the centerline of the rim. If the et value is greater and becomes a negative value, then it proves that the rim installed on the body will deviate from the outside. So in other words, dif...
The aluminum alloy wheels forged in our country use 6061 grade aluminum alloy (LD30). Compared with traditional steel wheels, they have the advantages of light weight, beautiful appearance, and good heat dissipation performance. However, due to the limitations of 6061 material, under the existing commonly used forging methods, its good mechanical properties can only reach tensile strength of 350Mp...
The closed forging process of the outer ring of automobile wheel rim includes cutting: the blank is made by sawing process, heating: the blank is heated to 1100~1400℃, upsetting: the blank is upsetting on the upsetting equipment to obtain a drum-shaped blank, pre-forging: The drum-shaped blank is made of pre-forged parts through the pre-forged die, precision forging: The pre-forged parts are ...
The selection of wheels, how to choose the best one?Many people will transform the car at will in order to change the performance of the car. The transformation of the car requires professional knowledge. For the wheel rim, we cannot arbitrarily increase its diameter. 1. Don't blindly increase the wheels.Some people increase the wheels to improve the performance of the car. When the outer diameter...
Aluminum alloy wheels have the advantages of fuel saving, good heat dissipation, extended engine life, good roundness, and durability. They have been widely used in the automotive industry. Aluminum alloy wheels have a beautiful appearance and have become a fashion in many countries and regions. The surface coating process of aluminum alloy wheel hub includes: first pretreatment of the wheel hub, ...
When driving in normal times, you may encounter fever in the wheels of the car. Many people may think that the car is damaged or caused by some other reason.This is a very simple question, so don't worry too much. The reason for its heat may be that the tire rubs against the ground for a long time and then generates heat that will be transmitted to it, and then it will cause its temperature to ris...
Three-piece aluminum alloy wheels are tightened by a central member and two outer rings and screws. In order to reduce quality, many three-piece aluminum wheels use forgings. Three-piece aluminum wheels use forgings. The three-piece structure provides manufacturers with greater flexibility for small batch manufacturing. For high-speed vehicles, high-temperature tire bursting and reduced braking ef...
