Car front fender action
The main functions of automobile front fender include :
Protect the bottom of the compartment : the front fender can prevent the wheel rolled up sand, mud and other debris from splashing to the bottom of the compartment, so as to protect the interior of the compartment clean and safe .
reduced drag coefficient : The design of the front fender helps to reduce the drag coefficient and make the car run more smoothly .
Protection of tires and mud : fender can protect tires and mud, prevent dirt, stone and other debris damage to the wheel and brake system .
Perfect body modeling : The shape and position design of the front fender helps to maintain the perfection and smoothness of the body lines and enhance the overall aesthetic of the vehicle .
Material selection and design requirements for front fender :
Material choice : 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 can reduce the injury to pedestrians in the event of collision and can withstand certain elastic deformation, making maintenance more convenient .
The front fender is a part of the body of an automobile and is 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 when turning and jumping. 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 decision to repair or replace a faulty front fender of an automobile depends mainly 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.
