What is a car front fender
The front fender (also known as the front fender) of a car is a metal or plastic covering part located on the outside of the front wheels of the vehicle. It mainly serves to prevent dust, protect the chassis and assist in aerodynamics.
Structure and Function
The front fenders are installed on both sides of the vehicle body, covering the area above the wheels, and are made of metal or plastic materials. Its position ensures that there is sufficient space when the wheels rotate, while preventing foreign objects such as sand, gravel, etc. from splashing onto the chassis, reducing damage to the chassis. Some models are made of elastic plastic to enhance the buffering performance.
Aerodynamic effect
The design takes into account both dust-proof function and aerodynamic characteristics. It reduces the wind resistance coefficient through smooth lines, enhancing fuel economy and driving stability.
The front fender of a car (also known as the fender) mainly has the following functions:
Dust-proof protection
The front fender covers the wheels, effectively preventing sand, mud and other debris lifted by the wheels from splashing to the bottom of the vehicle, thus avoiding wear and corrosion to the chassis and suspension system.
Aerodynamic optimization
The streamlined design reduces air resistance, lowers the wind resistance coefficient, enhances driving stability and handling, and simultaneously reduces fuel consumption.
Heat management
In coordination with the front wheel arch layout, guide the airflow to dissipate heat from the engine compartment and braking system, ensuring that key components are at an appropriate working temperature.
Noise control
By using sound-absorbing materials or special structural designs, the noise generated by the friction between tires and the ground and the turbulence of air flow can be reduced, thereby enhancing the comfort of driving and riding.
Spatial adaptation
Reserve sufficient space for the front wheel steering. Verify the design dimensions through the "wheel runout diagram" to ensure that the wheels can rotate freely during driving without interfering with the fenders.
The repair method for the malfunction of the front fender of a car depends on the degree of damage:
Minor damage can be repaired
If there are only minor scratches or depressions, they can usually be repaired through sheet metal processing, preserving the original factory structure at a relatively low cost.
Severe damage requires replacement
If the damage is irreparable or affects the structural strength (such as severe deformation or cracking), it is recommended to replace the parts with new ones. When replacing, pay attention to the protection of the original factory welding points to avoid damaging the integrity of the vehicle body frame.
Maintenance suggestions
Giving priority to professional sheet metal and painting repair can save 60% of the cost without affecting safety. If replacement is required, make sure that the parts match the original factory dimensions to avoid affecting the wheel rotation space or aerodynamic performance.
There are mainly three types of materials for the front fenders of automobiles: plastic, metal (steel), and aluminum alloy.
Material type
Youdaoplaceholder0 plastic : Commonly found in the front fenders, it is made of elastic materials to reduce the splashing of sand, gravel and mud onto the bottom of the vehicle. It features resistance to weathering and good formability.
Youdaoplaceholder0 steel : Metal materials have high strength and low cost, making them suitable for scenarios that require high structural stability.
Youdaoplaceholder0 aluminum alloy : light in weight and corrosion-resistant, it can improve fuel economy and handling performance, and is gradually becoming the mainstream choice.
Differences in material selection
The front fenders of some models are made of plastic, while steel and aluminum alloy are mostly used in other parts. For instance, the fenders made of carbon fiber reinforced plastic weigh 50% less than those made of steel, which can effectively reduce fuel consumption.
