Classification and characteristics of wheel rims

According to the material of the wheel, it can be mainly divided into two categories: steel rim wheels and alloy wheels.

1. Steel rim wheels

The models with steel rim wheels are generally based on cost considerations, because the cost of steel rim wheels is low, the manufacturing process is simple, and the steel rim wheels are stronger than the alloy wheels. The disadvantage is that the weight is heavy, the inertia is large, which is not conducive to fuel saving, and due to the structural problems of the steel rim, the heat dissipation efficiency is not as good as that of the alloy material, which is not conducive to brake heat conduction, which may cause the braking efficiency to decline. In addition, owners equipped with steel rim wheels should not park their vehicles for a long time, and try to move the vehicle every week to prevent the irreversible occurrence of slight deformation of steel rim wheels.

2. Alloy wheels

Alloy wheels are divided into two forms: forging and casting. In addition to the above two original processes, there is now a new process form, called MAT spin casting. There is not much to say about the difference between them. The advantages of alloy wheels are very obvious, lightweight, beautiful appearance, conducive to heat dissipation, small movement inertia, high manufacturing accuracy; The disadvantage is that the cost is a little high relative to the steel ring, considering the cost of the car companies will abandon the alloy material wheel, the manufacturing process is relatively complex compared to the steel ring, and the appearance is easy to bump and damage.

Due to the particularity of steel rims, the rim maintenance we say here is mainly about alloy rims.

If the vehicle has just finished running, do not immediately carry out rim cleaning, because during the driving process, with the tire heating and the use of braking, the temperature of the rim increases. It is recommended to stop for a period of time, such as until the temperature is down after the cleaning operation.

The wheel is very close to the road and close to the brake disc, so the wheel is often very easy to get dirty parts, usually the road is thrown up the dirty things and the brake disc after the brake powder, it is recommended not to use a hard brush to clean, the use of special cleaning liquid with a soft brush is easy to wash off the dirt attached to the above.

When driving, pay attention to avoid pothole sections, and slow down when crossing speed bumps. Especially the rim wheel, if the rapid passage through the pothole section is likely to cause irreversible deformation of the rim, once the deformation occurs, it may occur at high speed when the body beats, affecting the stability of the vehicle. Although the alloy wheel is not easy to deform, once there is a slight deformation, it is necessary to do the dynamic balance of the vehicle, and if he deformation is more serious, the wheel needs to be replaced.

Do not park the vehicle for a long time; it is recommended to move the vehicle appropriately every week to prevent the deformation of the wheel rim and also to prevent the occurrence of irreversible deformation of the tire.

Can damaged wheels be repaired?

The answer is yes. If the wheel has a slight scratch, it should be repaired immediately. If the scratch is more serious, see whether the primer is exposed. If the primer is exposed, it needs to be repaired immediately, as any delay will lead to rust, which can not be repaired.

Generally speaking, a gap greater than 3 cm should not be constructed. The repair must go to the regular shop. According to the size of the damage, the repair method will be different, and the wheel after treatment generally needs to be balanced.
