What are the rear wheel arches of a car
The rear wheel arch of a car is a body component located above the rear wheels of the vehicle. It usually refers to the semi-circular or semi-arc-shaped covering that protrudes along the fender on the tire, also known as the wheel arch cover.
It is mainly made of materials such as plastic, rubber or stainless steel, serving to decorate and protect the vehicle body.
Functionally, the rear wheel arch can reduce wear when the wheel hub is in direct contact with the vehicle body, prevent water and sand from splashing into the vehicle, and at the same time help lower the wind resistance coefficient and enhance the vehicle's driving stability.
From the perspective of exterior design, it can enhance the three-dimensional effect and sporty atmosphere of the vehicle body, meeting personalized demands.
For the rear wheels, their structure is similar to that of the front wheels, but the specific shape may vary depending on the model. They are commonly made of black plastic.
The main functions of the rear wheel arches of a car include protecting the vehicle body, enhancing its aesthetic appeal, optimizing aerodynamic performance, and meeting personalized demands. Specifically:
Youdaoplaceholder0 Protective function : The rear wheel arches can prevent the parts of the wheels that come into contact with the ground during driving from directly rubbing against the vehicle body, reducing scratch damage. At the same time, they protect the wheel arches from being hit by stones, branches and other debris, especially providing additional protection on rough roads or off-road conditions.
Youdaoplaceholder0 Decoration and aesthetics : The rear wheel arches are usually made of the same color material as the vehicle body. After installation, they can make the vehicle's appearance neater and more harmonious, and visually extend the width of the vehicle body, making the vehicle appear more stable or more powerful.
Youdaoplaceholder0 Aerodynamic optimization : Some wheel arch designs can reduce air resistance during driving and lower the drag coefficient, which may enhance fuel economy and high-speed stability.
Youdaoplaceholder0 Personalized modification : Wheel arches can be part of the vehicle's exterior modification, highlighting the owner's personalized style through different styles, colors or materials (such as chrome plating, stainless steel).
It should be noted that wheel arches are not essential components of a vehicle. Whether they are installed or not depends on the driving environment (such as whether one often passes through complex road conditions) and personal aesthetic preferences.
In addition, poor-quality or improperly installed wheel arches may increase air resistance or pose safety hazards. It is recommended to choose reliable products and install them in a standardized manner.
Faults in the rear wheel arches of a car may manifest as damage or inconsistent heights, and should be dealt with based on specific symptoms. The following provides solutions in combination with common situations.
Repair methods for damaged wheel arches: wheel arch damage is mostly caused by scratches, stone impacts or aging.
Youdaoplaceholder0 Minor scratches : If there are only scratches on the surface and no damage, it can be repaired by yourself. First, use sandpaper to smooth the scratched area. After cleaning, apply a touch-up pen that matches the color of the car paint evenly. After it dries, polish it to enhance the integration.
Youdaoplaceholder0 Cracks or large damages : For small areas of damage, plastic welding can be attempted. Professional tools should be used to align the fracture for welding, followed by grinding and painting. If the damage is severe (such as large area cracks or fractures), the strength and aesthetic appearance after repair cannot be guaranteed. It is recommended to directly replace the wheel arch with a new one.
Youdaoplaceholder0 Severe rust or deformation : The rusted and rotten parts need to be cut off, ground clean, and then the same shape components should be made of iron sheet and welded. After that, they should be restored through processes such as grinding, applying putty, and painting.
When replacing the wheel arches, choose genuine parts that match the vehicle model and install them according to the instructions.
Troubleshooting and handling of inconsistent height of wheel arches: inconsistent height of is usually related to the suspension system or load.
Youdaoplaceholder0 Initial inspection : First, park the vehicle on a flat ground and check if the tire pressure on both sides is balanced and if there is any damage or air leakage in the tires. If the air pressure is insufficient and you need to inflate or replace the tires, it is recommended to replace them in pairs or all four at the same time to maintain consistency.
Youdaoplaceholder0 Load and suspension issues : If the vehicle has been under heavy load on one side (such as having heavy objects in the trunk for a long time), you can first reduce the load and drive for a certain distance to observe whether it recovers. If it is ineffective, it may be caused by oil leakage from the shock absorber, loss of elasticity of the spring or deformation of the chassis components. The shock absorption system needs to be replaced or the chassis components inspected.
Youdaoplaceholder0 Collision or abnormal after repair : If the vehicle has been involved in a collision or has inconsistent heights after repair, it is necessary to go to a professional repair shop or 4S store for a comprehensive inspection to avoid potential safety hazards.
If the cause cannot be determined after self-examination, professional personnel should be sought for testing.
