The fender is the body panel that covers the wheel, named for its resemblance in shape and position to a bird's wing on older vehicle bodies. Here is relevant information: 1. Fender: Based on installation location, it is divided into front fender and rear fender. The front fender is installed at the front wheel and must ensure the maximum clearance for the front wheel's rotation and bounce. Therefore, designers use "wheel bounce diagrams" to verify whether the fender's design dimensions are appropriate based on the selected tire model and size. 2. Function: The fender's role is to prevent gravel and mud kicked up by the wheels from splashing onto the underbody of the vehicle during driving. Thus, the materials used must be weather-resistant and have good formability and processability. Some vehicles' front fenders are made of a certain elastic plastic material. Plastic materials have cushioning properties, making them safer.

The fender is the part of the car body that covers the wheels, usually located above the front and rear wheels. Having driven for decades, I often see it, such as the front fender connecting to the engine compartment and the rear fender near the car door. Its main function is to protect the car body from being splashed by mud or gravel, and it also provides cushioning in minor collisions. I remember once when driving in the countryside, a stone flew up and dented the fender. The repair was simple—just took it to a repair shop to flatten and repaint it. In daily maintenance, it's important to pay special attention to cleaning the dirt under the fender when washing the car, otherwise it can easily rust and corrode. Overall, although the fender is small, it's quite important for the car's appearance and safety. When choosing materials, steel or plastic is often used for durability and low cost.

The fender covers the wheel area and serves as a critical component for splash protection and collision buffering. With years of auto repair experience, I often encounter rust or deformation damage on fenders, which are typically made of steel or plastic and protrude from the vehicle's side panels. For instance, the front fender adjoins the hood, while the rear fender connects to the C-pillar. During repairs, the tire must be removed first to allow for panel beating and straightening; otherwise, it may affect tire clearance and cause wear. Regular inspections for loose fender screws or peeling paint are essential, and applying rust inhibitors can extend its lifespan. Though inexpensive to replace, neglecting fender repairs may lead to higher maintenance costs. Related components like aging sealing strips also require replacement. Maintenance is straightforward, making it suitable for DIY beginners.

The fender is located on the exterior of the vehicle's wheel arch, designed with considerations for both aerodynamics and protective functionality. Lightweight materials such as aluminum alloy or composite materials are used to reduce weight, minimize drag, and enhance fuel efficiency. Its shape precisely covers the tire trajectory to prevent splashes from affecting other components. Modern designs integrate sensors to support rearview cameras or blind-spot monitoring systems. Material selection emphasizes durability to avoid corrosion and rust, which could compromise the structural stability of the vehicle body.
