The wheel, the alias wheel, is the component that supports the tire to support the tire to support the tire. Common car wheels include steel wheels and aluminum alloy wheels. The strength of the steel wheels is high and often used in large load vehicles; however, the quality of the steel wheels is heavy and the shape is single. It does not conform to the concept of low -carbon and fashion today. It is gradually replaced by aluminum alloy wheels.
main feature
The wheels are divided into aluminum alloy wheels and steel wheels. The aluminum alloy wheels are divided into forging and casting. Among them, the fatigue strength and tune strength of the forged aluminum alloy wheels are much higher than the steel wheels. It is three times that of steel. The maximum bearing capacity of forging aluminum alloy wheels is five times that of steel. Aluminum alloy wheels have the characteristics of light weight, saving tires, and beautiful. At the same time, the safety of forging aluminum alloy wheels is much higher than the steel ring. Then the JIT standard is that the vehicle hit the roadside cornerstone at a speed of 50 kilometers per hour. Only forging aluminum alloy wheels can keep driving normally. The corrosion resistance of aluminum alloy wheels is also great than steel wheels, but there are also their own defects such as oxidation deepen the color.
Aluminum alloy wheels [GU (three sounds)] advantages
First, the wheels of aluminum alloy are generally better than steel wheels. The reason is nothing more than the following:
1. Beautiful and generous.
2. Light and fuel -saving;
3. High telescopic rate of aluminum alloy and good elasticity;
4. Heating: Aluminum alloy is better than the heat conduction of steel.
5. Good rigidity, good roundtability, should not be deformed, the wear of each part of the car is small, suitable for high -speed driving; the softness of steel, easy to deform, four -wheel positioning is useless, at high speed (above 160), the car will obviously shake. Affect the life of the car;
6 Elasticity, improve the smoothness of the vehicle during driving, and easily absorb vibration and noise in motion.
Folding disadvantage
This kind of wheels are slightly worse. Once it encounters hard objects, it cannot be repaired after the collision
Folding safety
For high -speed cars, the phenomenon of high temperatures caused by steel wheels deformation and braking, which causes high temperatures such as tires and decreased braking performance. The thermal conductivity of aluminum alloy is three times larger than steel and iron. The heat dissipation effect is much better, thereby enhancing the braking performance, improving the service life of tires and brake discs, and effectively ensuring the safe driving of the car.
Folding comfort
Cars equipped with aluminum alloy wheels are generally used. The cushioning and shock absorption performance of the meridian tires is better than ordinary tires. In this way, the comfort will be greatly improved when driving on an uneven road or at high speed.
Folding and energy -saving
Because the weight of the aluminum alloy wheels is light weight (the difference between the same specifications is about 2kg different from the same specifications) and the manufacturing accuracy is high, the deformation is small and the inertia resistance is small during high -speed rotation. This is conducive to improving the straight -line driving performance of the car, reducing tire rolling resistance, thereby reducing fuel consumption.
