What Is a Daughterboard?
The fender is a body outer panel that covers the wheels. It is named because the shape and position of the part on the old-style body resembles a bird's wing. According to the installation position, it is divided into front fender and rear fender. The front fender is installed at the front wheel. It must ensure the maximum limit space when the front wheel rotates and bounces. Therefore, the designer will Dimensions Use the "wheel beating diagram" to verify that the design of the fender is appropriate.

- The fender is a body outer panel that covers the wheels. It is named because the shape and position of the part on the old-style body resembles a bird's wing. According to the installation position, it is divided into front fender and rear fender. The front fender is installed at the front wheel. It must ensure the maximum limit space when the front wheel rotates and bounces. Therefore, the designer will Dimensions Use the "wheel beating diagram" to verify that the design of the fender is appropriate.
- The rear fender does not have the problem of wheel rubbing, 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 of the car, and they are produced in one go. However, the fenders of some cars are independent, especially the front fenders, because the front fenders have more collision opportunities, and the independent assembly is easy to replace the whole.
- It is placed above the wheels of the vehicle as an outer panel on the side of the vehicle and is molded from resin. The fender is integrally formed from the outer panel and the reinforcement with resin. The outer panel is exposed on the side of the vehicle and the An edge portion of the outer plate portion, which is disposed on the back of the adjacent member adjacent to the outer plate portion, extends along the edge portion of the outer plate portion and the reinforcing portion, and a mating portion for mating the adjacent member is formed.
- The function of the fender is to prevent the gravel and mud rolled up by the wheels from splashing into the bottom of the compartment during the driving of the car. Therefore, the materials used are required to have weather resistance and good moldability. The front fenders of some cars are made of a certain elastic plastic material. Plastic materials are cushioning and relatively safe. There are two fenders above the left and right front wheels of the Santana sedan, which weighs about 1.8Kg. It is injection-molded from toughened and modified PP; the fenders of King Castell are made of FRP fiberglass SMC material; The fender of Taier 1491 is made of PU elastomer. In the future, injection molding with PA / PP alloy is a relatively broad development direction.
