Fender, also known as fender, is divided into front fender and rear fender according to the installation position. Refers to a kind of covering on motor vehicles and non-motor vehicles.
When the front fender is installed at the front wheel, it must ensure the maximum limit space when the front wheel rotates and jumps, so the designer will use the "wheel jump diagram" to verify whether the design size of the fender is appropriate according to the selected tire model size.
There is no wheel rubbing problem on the rear fender, but due to aerodynamic considerations, the rear fender is slightly arched and protrudes outward. The fenders of some cars have been integrated with the body in one go. However, there are also fenders of cars that are independent, especially the front fender, because there are many collision opportunities of the front fender, and it is easy to replace the whole piece by independent assembly.
function
Mudguard is also called mudguard (named after the shape and position of this part on the old car body like bird wings). The fender is located outside the wheel body. The function is to reduce the drag coefficient according to fluid mechanics and make the car run more smoothly.
According to the installation position, it is divided into front fender and rear fender. The front fender is installed above the front wheel. Because the front wheel has steering function, it is necessary to ensure the maximum limit space when the front wheel rotates. Therefore, the designer will use the "Wheel Runout Diagram" to verify the design size of the fender according to the selected tire model size.
There is no wheel rubbing problem on the rear fender, but due to aerodynamic considerations, the rear fender is slightly arched outward.
Secondly, the front fender can prevent the silt rolled up by the wheels from splashing to the bottom of the carriage, thus reducing the damage and corrosion to the chassis. Therefore, the materials used are required to have weather resistance and good formability. The front fenders of many cars are made of plastic with certain elasticity, which is more cushioning and safer.
