[China Aluminum Network] Wheel hubs usually have two kinds of alloy rims and traditional steel rims. Compared with the latter, the former has many advantages.
1. The quality is small. Aluminum rims should be light and small steel rims, which can make a great contribution to vehicle fuel economy.
2. Good heat dissipation, can improve tire life. Some aluminum alloy rims can rely on their own shape of the function, in the rotation will be the air flow guide the brake to improve heat dissipation.
3. High roundness can improve the accuracy of the wheel's movement and is suitable for high-speed driving.
4. Good energy absorption, can absorb vibration and noise from the road surface, improve the ride comfort of the vehicle.
5. High rigidity can effectively reduce the impact of road impact on the rim shape.
6. There are few restrictions on the shape, and various types of rims can be designed as required.
The quality of the hub directly affects the safety of driving.
Owners should check the rims during daily inspections because the problematic rims will not only aggravate tire wear, but will also affect the handling and safety of the vehicle. Common problems with rims are surface corrosion and fatigue deformation. Corrosion of the surface not only affects the appearance, but more importantly it will affect the heat dissipation, especially in the high-speed driving, if the heat cannot be dissipated in time, it will accelerate the aging of the tire rubber tissue. Because the rims bear the weight of the vehicle body for a long time, the lateral load during the cornering, the driving force and the braking torque, the rims are prone to fatigue deformation or cracks, which is very unfavorable for driving safety.
First, after cooling, cleaning, because the high temperature aluminum alloy rims and detergents will lose their luster chemical reaction, affecting the appearance. In addition, it should be noted that when cleaning, do not use cold water, because cold water at high temperatures will damage the aluminum alloy rim, and even make the brake disc deformation and affect the braking effect.
Second, when vehicles are driving in humid areas such as the southeast coast, they should be cleaned frequently. Because the moist air and salt will accelerate the corrosion of the aluminum alloy rim surface, it is necessary to clean it with an acid-resistant cleaner as far as possible during cleaning. It is better to wax the rim at regular intervals (about 2 months). To make it lasting gloss.
Third, when the surface of the rim is difficult to remove the tar stains, the use of professional tar cleaning agent, this cleaning agent is often able to gently and effectively remove stains, reduce the damage to the aluminum alloy surface. Under limited conditions, you can also try to clear with a brush, but be sure not to use a hard brush, especially iron brush, so as not to leave scratches. The rim itself has a layer of metal protective film, so be careful not to use paint brighteners or other abrasive materials when cleaning.
Fourth, during the driving process, be careful to avoid the “hard injuries†caused by rims. Once scratches or deformations occur, they should be repaired and repainted as soon as possible. In such cases, it is better to go to a professional repair station.
In addition, in recent years, aluminum alloy rims have become more and more popular, which is related to its small quality, fuel-efficient, anti-deformation ability, small loss of power, good heat dissipation, beautiful appearance, but objectively. Speaking of aluminum alloy rims also has many shortcomings, because the aluminum alloy material itself is relatively brittle and easy to appear small cracks, so it is difficult to be found, its strength is not high with steel materials, coupled with relatively high prices, we are in the election It is still necessary to carefully consider when purchasing and maintaining aluminum alloy rims.
First, look at the brightness of the paint surface. The lacquer sheen of good quality aluminum alloy rims is vivid and pure, while the poor quality rim lacquer finish is dull.
Second, see if there are no pinholes and cracks. If there are pinholes and small cracks on the rim surface or in the inner circle, there is a problem in the manufacturing process of the rim. Touching a finger to see if the surface finish is sleek is a sign of quality.
Third, look at the rim structure. The rims with complex and varied structures are indeed quite beautiful, but this is a headache for cleaning and maintenance. Do not blindly pursue a beautiful, easy to clean is more important.
Fourth, look at the size. Some people blindly increase the size of the rim in order to improve the performance of the car. Increasing the size of the rim can indeed reduce the lateral swing of the vehicle, but at the same time it will also reduce its ability to absorb vibration and it will easily damage the tire. In general, the rim size is more suitable than the size of the original car, and the parameters such as hole pitch and eccentricity are also suitable for the model. It is better to consult the professional when buying.
