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 ...
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...
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 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, ...
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...
1. In order to maximize safety and reliability, it is recommended that you always check the hub bearings no matter how old the car is-pay attention to whether the bearings have early warning signs of wear: including any friction noise during rotation or abnormal deceleration of the suspension combination wheel when turning.For rear-wheel drive vehicles, it is recommended that the front wheel hub b...
Automobile wheels include hub bolt holders, drainage spiral blades and rims. The structural points of the hub bolt holders and rims are provided with drainage spiral blades to drain air to the outside of the hub, but the drainage spiral blades can drive the air flow when the wheel rotates, and the air flow forms wind, but the guide spiral blades guide the air flow from the inside of the car to the...
A one piece forged wheel rim is a type of wheel that is made from a single piece of forged aluminum or other lightweight metal. The forging process involves heating the metal and shaping it with hydraulic presses or hammers, resulting in a stronger and more durable wheel compared to cast wheels. One piece forged wheels have become popular among car enthusiasts and high-performance vehicles because...
1.Material selection: The material of the wheel rim will directly affect the strength of the wheel rim.Common materials are aluminum alloy, titanium alloy, carbon fiber, etc. 2.Design structure: The structural design of the rim will affect the strength of the rim, such as the wall thickness and bending radius of the rim. 3.Manufacturing process: Different manufacturing processes will lea...
After decades of development, China's automobile industry has become an important industry in the national economy. With the progress of technology and the improvement of various performance indicators of automobiles, governments of various countries have become more and more stringent requirements for energy conservation and environmental protection. Therefore, automobile lightweight has become t...
If you encounter a situation where the car tire is pierced with a small nail and taken off but there is no air leakage, it doesn't matter, we can not repair it.But we need to carry out testing. We can't just ignore it if it looks like there is no air leakage to the naked eye, but we can continue to use it after we are truly sure that there is no air leakage. It doesn't matter that the car tire is ...
