Automobile front wheel liner refers to the protective cover on the inner side of the wheel hub, which is used to protect the axle, braking system and parts on the inner side of the tire. When the car is running, the dust and sand on the front wheel will adhere to the hub, and the shield on the inner side of the hub can prevent these impurities from entering the braking system and the interior of the axle and prevent these components from being damaged. In addition, the lining can also play the role of sound insulation and noise reduction, reducing the spread of road noise. The material of the lining is generally plastic or metal, and the specific types and materials will be different for different models and manufacturers.
