What is the plastic ring above the wheel called?
2 Answers
The plastic ring above the wheel is called a wheel arch cover. The wheel arch cover is installed above the four wheels of the motor vehicle, effectively preventing mud and stones kicked up by the rotating tires, reducing impact on the vehicle body, minimizing noise, and providing excellent protection for the body section, thereby extending the service life of the motor vehicle. Here is more information about wheels: Function of wheels: Wheels are rotating components between the tires and axles that bear loads. Their purpose is to mount tires and withstand various loads between the tires and axles. Composition of wheels: Wheels are generally composed of a hub, rim, and spokes. The hub is mounted on the axle or steering knuckle shaft diameter via tapered roller bearings, connecting the wheel to the axle. The rim is used to mount and secure the tire. The spokes connect the hub and rim and are bolted to the hub.
That circle of plastic above the wheel, commonly called the wheel arch liner or fender liner, silently protects the engine compartment from being eroded by splashing gravel or rainwater when my car runs in the city every day, preventing parts from rusting. The plastic material is durable and lightweight, but it is prone to trapping stones and cracking on bumpy roads. It is recommended to check and clean it during car washing. Replacing a new one costs about fifty to one hundred yuan, which is very cheap. After driving my car for many years, I found that regular maintenance of this small component can extend the chassis's lifespan and reduce repair costs. It also helps reduce noise on highways, making driving quieter and more comfortable. If its damage is ignored, sand and mud clogging the ventilation ports can lead to poor heat dissipation, causing bigger troubles.
