It is normal for car hubs to get hot. The heating of the hub is caused by excessively tight bearing assembly or poor lubrication. The car hub refers to the cylindrical metal component inside the tire that supports the tire, with its center mounted on the axle. It is also known as the wheel rim or steel rim. It is an important part connecting the brake drum or brake disc, wheel disc, and half-shaft, working with the tire to support the wheel and also determining the tire specifications. The functions of the car hub are: 1. The part where the axle is installed, used to support the tire and cushion external impacts; 2. To achieve contact between the tire and the road surface, ensuring the vehicle's driving performance. The maintenance methods for the hub are: 1. Avoid using cold water for cleaning when the temperature is high; 2. If the vehicle is parked in a damp location for a long time, it needs to be cleaned regularly to prevent salt corrosion.
