What is a car front fender
The front fender is a part of the body of an automobile, mainly installed at the position of the front wheels of a vehicle, to cover the wheels and ensure that the front wheels have enough room to turn and jump. Front fenders, usually made of plastic or metal, are designed with hydrodynamic considerations in mind to reduce drag coefficient and improve driving stability .
Material and design
The front fender is usually made of metal, but some models may also use plastic or carbon fiber. Because the front fender is prone to collisions, screws are often used to allow replacement if needed .
The design needs to consider the maximum limit space of the front wheel, usually through the "wheel runout diagram" to verify the suitability of the design size .
Function and importance
The main functions of the front fender include:
prevent sand and mud sputtering : in the process of vehicle running, the front fender can effectively prevent the sand and mud rolled up by the wheels from splashing onto the bottom of the car .
improve driving stability : through optimization design, reduce air resistance, improve vehicle driving stability .
Patents and technology development
In the field of technology, patents and technical innovations related to front fender panels continue to emerge. For example, Great Wall Motor has obtained a patent on fender reinforcing structures and vehicles, enhancing the strength and durability of fenders by adding reinforcing plates .
In addition, Ningbo Jinruitai Automobile Equipment Co., Ltd. also obtained a patent for the inspection of the front fender windscreen, aiming at improving 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 .
reduce drag : The design of the front fender helps to reduce the wind drag coefficient, make the car run more smoothly, improve the stability of the vehicle and fuel economy .
Protection of tires and mud : the front fender can protect the tires and mudguards, prevent dirt, stones and other debris from invading the wheels and brake system, and ensure the normal operation of the vehicle .
perfect body modeling : The design of the front fender can improve the body modeling, maintain the perfection and fluency of the body line, and improve the overall beauty of the vehicle .
Characteristics of material and design of front fender :
The front fender is usually made of a plastic material with a certain degree of elasticity. Although the strength of this material is low, it can reduce the injury to pedestrians in the event of a collision, and can withstand a certain degree of elastic deformation and resist minor collisions, making maintenance more convenient .
The decision to repair or replace an automotive front fender failure mainly depends on the severity of its damage . If the damage is not serious, you can use the sheet metal technology to repair, avoid replacement; But if the damage is too severe and beyond the scope of sheet metal repair, then replacing the front fender will be a necessary option .
Repair method
Front fender repair methods mainly include the following steps:
Removing screws on the pressure rubber strip and fender : Remove the pressure rubber strip under the front windshield using an adjustable socket wrench and screwdriver, remove the screws on the fender in sequence, and remove the fixing devices around the fender .
Using the repair tool : The repair can be done using a shape repair machine or an electric suction cup. The shape repair machine vibrates the leaf back to its original shape, while the electric suction cups use suction to pull the leaf back straight .
repair indentations : For sharp indentations, it is necessary to repair the edges first, usually using a crowbar to repair the indentations bit by bit from the inside according to the principle of leverage. After the deep depression is repaired, it is also necessary to deal with the edges and ridges. Use the sandalwood repair pen to smooth the ridges .
Failure causes and preventive measures
Causes of front fender failure may include damage caused by collisions, impacts, or other external factors. To prevent front fender failure, the following measures can be taken:
Regular inspection : Check the condition of the front fender regularly to identify and deal with potential problems in a timely manner.
Avoid collision : Take care to avoid collisions with other vehicles or sharp objects on the road while driving.
Reasonable driving : Avoid driving at high speeds in bad weather or complex road conditions to reduce the risk of damage to the front fender.
