What is a car front fender
The front fender of an automobile is an outer body panel mounted on the front wheels of an automobile. Its main function is to cover the wheels and ensure that the front wheels have enough room to turn and jump. The design of the front fender needs to take into account the type and size of the selected tire, and the rationality of the design size is usually verified by a "wheel runout diagram" .
Structure and function
The front fender, usually made of a resin material, combines an outer panel that is exposed to the side of the vehicle and a stiffener that runs along the edge of the outer panel, enhancing the strength and durability of the fender .
In addition, the front fender has the following functions:
prevent sand and mud sputtering : The front fender can effectively prevent the sand and mud rolled up by the wheels from splashing onto the bottom of the car during the process of driving.
aerodynamic optimization : Although the front fenders are mainly concerned with the space requirements of the front wheels, they are also designed to optimize the aerodynamic performance, usually showing a slightly arched arc that protrudes outward .
collision protection : The front fender can reduce the injury to pedestrians in the event of a collision and improve the pedestrian protection performance of the vehicle. The front fender of some models is made of a plastic material with a certain degree of elasticity, which provides better protection in the event of minor collisions .
Maintenance and replacement
The front fender is usually independently assembled, especially if it needs to be replaced after a collision, which makes the replacement more convenient. However, replacement costs may be higher if important components such as a gearbox or on-board computer are installed on the inside of the front fender .
The main functions of the front fender include the following aspects :
prevent sand and mud from splashing on the bottom : The front fender can effectively prevent the sand and mud rolled up by the wheels from splashing on the bottom of the car, thereby reducing the wear and corrosion of the chassis .
Optimize streamline design and reduce drag coefficient : according to the principle of fluid mechanics, the design of front fender can optimize the streamline of vehicle, reduce drag coefficient and ensure a more stable vehicle .
Protecting critical vehicle components : The front fenders are located above the wheels and provide sufficient space for the steering function of the front wheels while protecting critical vehicle components .
Material selection and design requirements for front fender :
Material requirements : The front fender is usually made of weather-aging resistant material with good formability. The front fender of some models is made of plastic material with certain elasticity, which not only enhances the cushioning performance of the components, but also improves the driving safety .
Design requirements : The design of the front fender needs to take into account the streamlining and aerodynamic characteristics of the vehicle. The front fender is usually mounted on the front section, snug above the front wheels, ensuring adequate space and protection for the vehicle .
