Fender has the following functions:
1、? With the help of fluid mechanics, the drag coefficient is reduced and the driving is more stable.
2、? In the process of driving, avoid the sediment rolled up by the wheels splashing to the bottom of the car.
Because the front wheel has steering function, it is necessary to ensure the maximum limit space when the front wheel runs, so the designer will use the "wheel lion diagram" to verify the design size of the fender according to the selected tire model size.
