The inner lining function of the front fender
The front fender liner is a component installed above the front wheels of a car and attached to the inner edge of the wheels. Its main functions include:
Protect the vehicle body and chassis
Block the sand, gravel, mud and other foreign objects lifted by the wheels to prevent damage and corrosion of the chassis, and at the same time reduce the erosion of the engine compartment.
Improve driving stability
Based on aerodynamic design, the coefficient of wind resistance is reduced to make the vehicle run more smoothly.
Reduce noise pollution
Reduce the transmission of tire noise into the cabin to enhance driving quietness.
Ensure the movement space of the front wheels
Design based on the tire model and size to ensure that the front wheels have sufficient space when steering and bouncing.
The materials are mostly made of high-toughness plastics, taking into account both lightweight and protective performance.
The main material for the inner lining of the fender is plastic, followed by steel plate and aluminum alloy. Among them, plastic material is widely used due to its light weight, rigidity and anti-concave performance.
Common material types and characteristics
Youdaoplaceholder0 plastic : The most common, made of thermoplastic materials such as PE, PVC or PP, can be repaired by welding with plastic welding rods. Advantages include:
Light in weight, improving fuel economy;
It has sufficient rigidity and is not prone to deformation, with good anti-concave performance. It can effectively reduce vibration during high-speed driving.
Low cost and suitable for most vehicle models.
Youdaoplaceholder0 steel plate : high strength but heavy weight, mainly used in extreme road conditions or special vehicle models.
Youdaoplaceholder0 aluminum alloy : lightweight and corrosion-resistant, but relatively expensive, and thus less used.
Material selection and maintenance
Plastic materials have become the mainstream choice due to their comprehensive performance advantages, accounting for more than 80% of vehicle applications. If the inner lining is damaged, it should be replaced in time; otherwise, it may cause corrosion of the chassis or abnormal noise.
The repair method for the inner lining fault of the fender should be determined based on the degree of damage:
Youdaoplaceholder0 Minor damage (such as small cracks, local deformation) : It is recommended to repair it to prevent the problem from worsening and maintain the engine protection function.
Youdaoplaceholder0 Severe damage (such as extensive damage or deformation) : It needs to be replaced in time to prevent debris from entering the engine compartment and causing greater losses.
Cause of malfunction
Common causes include external impact, material aging, improper installation, etc. Regular inspections are necessary and bumps should be avoided.
Precautions
When disassembling, special tools should be used and the operation should be carried out carefully to avoid damaging other components.
The damage to the inner lining of the fender does indeed have a negative impact on the vehicle , mainly including increasing driving noise, reducing protection, affecting fuel economy, and possibly accelerating the corrosion of the chassis and body components.
Main impacts and repair suggestions
Damage to the fender lining (fender lining) can lead to the following problems:
Youdaoplaceholder0 Noise and comfort decline : The noise from tire rolling cannot be effectively isolated, and the noise in the cockpit increases significantly.
Youdaoplaceholder0 Weakened protective function : Loss of the ability to block mud, water, sand and stones, resulting in the chassis and fender sheet metal parts being prone to damage or corrosion.
Youdaoplaceholder0 Driving performance impact : It disrupts the fluid mechanics design, increases the wind resistance coefficient, and may affect driving smoothness and fuel economy.
The common causes of damage are that the tires hit the inner lining on bumpy roads or the limit size is too small. Fix suggestion:
Youdaoplaceholder0 Timely handling : Minor damage can be postponed, but severe cracks or missing parts need to be repaired or replaced immediately to prevent long-term corrosion.
Youdaoplaceholder0 Professional maintenance : prefer welding methods (flame welding or soldering iron welding) to avoid secondary damage caused by self-handling; The tires need to be removed, the installation area cleaned and the limit devices adjusted.
