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 front fender is usually made of plastic or metal, sometimes carbon fiber .
Structure and function
The front fender is located under the front windshield, next to the front end of the vehicle, and covers the sides of the body. Its main functions include:
Prevent sand and mud from splashing on the bottom : The front fender reduces the sand and mud rolled up by the wheels from splashing on the bottom of the car and protects the interior .
reduce drag coefficient : Based on the principle of fluid mechanics, the front fender helps to reduce drag coefficient and improve the stability of the vehicle .
ensure space : The design of the front fender needs to ensure the maximum limit space of the front wheel when turning and jumping, usually through the "wheel beat diagram" to verify the design size is suitable .
Materials and connections
The front fender is mostly made of metal, and some models are also made of plastic or carbon fiber. Due to the greater likelihood of collision, the front fender is usually attached to by screws.
Patented technology
In automotive manufacturing, the design and structure of the front fender are also protected by patents. For example, Great Wall Motor has obtained a patent for fender stiffening structure and vehicle, which includes fender assembly, first stiffening plate and second stiffening plate to enhance the strength and stability of the front fender .
In addition, Ningbo Jinruitai Automobile Equipment Co., Ltd. also obtained a patent for the inspection of the front fender windscreen, in order to improve the inspection efficiency and accuracy .
The main functions of the front fender include the following :
Protect the vehicle and passengers : the front fender can prevent the wheel rolled up sand, mud and other debris from splashing to the bottom of the car, so as to protect the bottom of the vehicle from damage, to ensure the cleanliness and safety of the interior .
Reduced drag and improved stability : The design of the front fender helps to reduce the drag coefficient while driving, making the car run more smoothly. Its shape and position are also designed to direct airflow, reduce air resistance and improve vehicle stability .
pedestrian protection : the front fender of some models is made of plastic material with certain elasticity. This material can reduce the injury to pedestrians in the event of collision and improve the pedestrian protection performance .
Aesthetics and aerodynamics : The shape and position of the front fender is designed not only to protect the vehicle, but also to perfect the body shape and keep the body lines perfect and smooth. Its design takes into account the principles of aerodynamics, and the rear is often designed with a slightly protruding arched arc .
Choice of front fender material : Front fender is usually made of weather-aging resistant material with good formability.
The decision to repair or replace an automotive front fender failure depends mainly on the severity of its damage.
If the front fender is not seriously damaged, it can be repaired using sheet metal technology without replacement. The repair process involves removing the rubber strip, unscrewing the fender holding screws, tapping the depression with a rubber mallet to restore it, and reinstalling the fender. For deeper depressions, a shape repair machine or an electric suction cup can be used to repair .
However, if the damage is too severe and goes beyond sheet metal repair, then replacing the front fender will be necessary. The front fender is attached to the fender beam by screws, so it can be replaced independently. It should be noted that the repair or replacement of body coverings does not affect the overall safety of the car, as their main function is to guide the airflow and enhance the aesthetics of the vehicle, while the real safety protection is provided by the body frame .
When buying a used car, it is important to check the integrity of the body frame, as damage to the body frame can affect the safety performance of the vehicle. If the body frame is damaged, the vehicle will be considered an accident vehicle and there is a safety hazard .
