Hub motors in the vehicle are relatively grounded, often due to external factors causing various degrees of damage. Common damage to the wheel hubs are: surface scratches, edge scratches, edge gaps, and so on.Don't underestimate these marks; if you don't take care of them in time, they will not only affect the aesthetic level of your vehicle but may also cause safety hazards on the road. This post summarizes the possible adverse effects of common wheel damage.
If the scratch area is not large and the depth is not deep, you don’t have to repair it, but if the surface of the hub is left with deep scratches, you should repair it.Because each hub motor will have a layer of protective varnish on the surface when it leaves the factory, its function is to protect the aluminum alloy material of the wheel from oxidation. If the surface scratches are serious, the protective varnish layer will be destroyed, and the aluminum alloy material in the wheel will oxidize. Especially at the edge of the wheel, if there are deep scratches and the edge is corroded, a long time without treatment will lead to the combination of the wheel and tire more and more closing, resulting in a slow leakage of the wheel. After a long time on the road, there is a certain security risk.
Hub corrosion is related to the process of the hub surface, generally, the water-plating hub is the most prone to corrosion. If the corrosion is less serious, the appearance of the hub makes it difficult to see the degree of corrosion because it is corrosion from the inside out. Some high-end vehicles will be equipped with hydraulic plating wheels for a long time to see the wheel from the inside out with corrosion marks. So, if you find the hub has some corrosion, replace it in time.
Wheel hub deformation is generally divided into internal deformation, lateral deformation, and hub-spoke deformation. The load-bearing force of the hub is mainly on the hub-spoke, so as long as the hub spoke is not deformed to break, it will not affect the safety of the entire hub. If the hub spoke is cracked, it's best to buy the wheel again for your safety. When the hub is deformed, it will be separated from the outside of the tire. Wheel edge deformation is basically over the pit, speed bumps, and other bad terrain caused by the car speed being too fast, so you are better off slowing down when traveling in special road conditions.
Cracking of the hub generally has the following reasons:1 with an explosion-proof tire: because the wall of the explosion-proof tire is hard, the buffer force is relatively weak, so when the tire is strongly impacted, the force of the tire will be transferred directly to the hub, so it is easy to cause the hub to crack.2 large-size wheels: due to the low flattening rate of the large wheel hub, the tire buffer is insufficient, so when the tire is hit by an external force, the external force will also be transferred to the hub, resulting in cracking.
