What is a car rear fender
The rear fender is located on the outside of the body of the wheel, in the semi-circle directly above the tire, also known as the fender. It is an important part of the car body, mainly divided into front fender and rear fender .
Function and effect
aerodynamic design : The fender adopts aerodynamic design, which can reduce the drag coefficient and make the car run more smoothly. This design not only improves the stability of the vehicle, but also reduces fuel consumption .
protective function : the fender can prevent the sand and mud rolled up by the wheel from splashing onto the bottom of the carriage, thus protecting the chassis from damage .
In addition, the fender can also absorb and slow down the external impact force to a certain extent, and enhance the protective ability of the body .
aesthetics and practicability : fender board as a covering part of the body, not only makes the appearance of the vehicle more beautiful, but also protects the internal structure of the body from external damage .
Design and installation
The size and shape of the fender is determined according to the model and size of the tire, ensuring that the tire does not interfere with the body when it is turned. The rear fender is usually designed with a slightly arched arc shape, which is not only designed for aesthetics, but also to enhance the aerodynamic performance of the vehicle and make the vehicle more stable at high speeds .
The main functions of the rear fender include the following aspects :
Reduce drag coefficient : The design of the rear fender is based on the principle of fluid mechanics, and the wind drag coefficient is reduced by optimizing the shape, which makes the vehicle more smooth and smooth at high speeds . This design not only improves the vehicle's aerodynamic performance, but also reduces the wind resistance during driving, thus improving the vehicle's fuel economy .
Protection : The rear fender can prevent the sand and mud rolled up by the wheel from splashing to the bottom of the carriage, so as to protect the car chassis from damage . In addition, it can avoid dust and gravel infestation on the bottom of the car, and ensure that the interior space is clean .
Enhance vehicle stability : the design of rear fender helps to control airflow, reduce body shaking, improve vehicle driving stability . Especially at high speeds, this effect is particularly obvious, can help reduce the body lift and shake, improve handling and grip .
The rear fender is located outside the body of the rear wheel of the vehicle at a semicircle directly above the tire . Located between the doors, bonnet and bumper, it is the outer body panel that covers the wheels .
The rear fender plays an important role in automobile construction. From an aerodynamic point of view, it can reduce the wind resistance coefficient when driving, which is of great help to the stability of the car. In addition, the rear fender also prevents the sand and mud rolled up by the wheels from splashing onto the bottom of the carriage, protecting the chassis .
The design principle of the rear fender is based on the selected tire model size, and the "wheel runout diagram" is used to verify its design size. Since there are no wheel running bumps in the rear wheels, the rear fender is usually designed with a slightly arched arc protruding outward to meet aerodynamic requirements .
