Maintenance points and precautions of automobile wheel hub

The quality of the wheel hub is related to the quality of the car tire, not only related to the safety of the owner's life, but also affects the overall image of the car body. Therefore, the daily maintenance of the wheel hub is essential. So if the wheel hub is damaged due to our improper maintenance, how can we repair it? The following small series will introduce it to you~

Precautions for daily maintenance of wheel hub:

1. When the wheel hub temperature is high, it should be allowed to cool naturally before cleaning. It is not allowed to clean with cold water, otherwise the aluminum alloy wheel hub will be damaged, even the brake disc will be deformed and the braking effect will be affected. When cleaning the aluminum alloy wheel hub at high temperature, chemical reaction will occur on the surface of the wheel hub, which will lose luster and affect the appearance.

2. When the hub is stained with asphalt that is difficult to remove, if the general cleaner is not helpful, try to remove it with a brush, but do not use a hard brush, especially an iron brush, to avoid damaging the surface of the wheel hub. Some experts introduced a kind of side prescription of removing tar: that is to choose medicinal "Huoluo oil" to smear, which can obtain unexpected effect.

Handling of hub damage:

1. To clean the wheel hub, paint diluent can be used to wipe around the scar to remove dirt. The deepest part of the scratch is difficult to remove the dirt, so you can clean it thoroughly with a toothpick. When cleaning, in order to prevent the irrelevant parts from being painted by mistake, it is best to paste the adhesive tape carefully around the scar. When there are stains on the surface of the wheel hub that are difficult to remove, professional cleaning agent should be selected. This kind of cleaning agent can remove the stains mildly and effectively and reduce the damage to the surface of aluminum alloy. The hub itself has a layer of metal protective film, so special attention should be paid not to use paint brightener or other grinding materials when cleaning.

2. After finishing the brush tip, apply the finishing paint to the damaged area of the wheel hub. After the paint dries, it will protrude slightly, which is convenient for the owner to observe.

3. To wait for the finishing paint completely dry, in the use of water-resistant paper dipped in soapy water to smear, so that the surface is smooth. Then use the mixture to rub out the light, and finally apply wax.

4. If there are deep scars on the wheel hub, and be sure to observe whether the metal surface is exposed. If the metal surface can not be seen, it will not rust, and you can concentrate on applying finishing paint. Use the nib of a pen to put it on, and then wait for the paint to dry completely. If it is found that the metal is exposed, it is better to replace it.

In addition, care should be taken during driving to avoid "hard damage" caused by scraping. Once there is scratch or deformation, it should be repaired and repainted as soon as possible. To avoid this phenomenon, when the car is returned to the new, it is necessary to wash the wheel rim of the vehicle every day at least once a week. First, wet it with water, then brush it with detergent and sponge, and then rinse it with plenty of water.
