The camber angle is generally 1-2 degrees. The camber angle means that the end of the wheel is tilted outward after assembly, that is, the intersection angle between the plan where the wheel is located and the vertical vertical plan. A tire with a splayed figure of eight is called negative camber, and a splayed figure of V is also called positive camber. Fashion sports vehicles or sports cars mostly choose negative inclination angle.
The camber angle of the rear tire can be adjusted by an eccentric screw at one end of the upper suspension wall, which is also used for adjusting camber angle professionally. If there is an eccentric screw on the hanging wall of the car system, it can be adjusted. At this time, it can be changed to an adjustable arm, and the adjustment of the adjustable arm is strong, so it is a practical operation. You can see the following figure:
For the accurate positioning of the front tire with independent suspension, the camber angle of the wheel is adjusted by the adjusting washer added between the arm shaft and the fixed bracket, so the adjusting washer can be adjusted as necessary.
the camber angle of the front tire has immediate harm to the cornering characteristics of the vehicle. On the one hand, it can make the wheel turn close to the vertical ground, reduce the rolling resistance and improve the lightness of the front tire turning control. On the other hand, the load of rolling bearing and locknut is reduced, the service life is prolonged, and the safety factor of turning is improved. In order to better avoid the deformation of the vertical road surface of the wheel once it is fully loaded, it is very likely that the upper end of the wheel will tilt inward, resulting in the damage of the coupling parts of the automobile tire. Generally, the vehicle will be calibrated with an external splayed angle of view of about 1 degree.
Harm to vehicles when camber is wrong
1. Too large positive camber will cause unilateral wear on both sides of the tire; The wear of suspension system parts is accelerated; The vehicle will veer towards the side with larger positive camber angle.
2. Too large negative camber angle will cause unilateral wear on the inner side of the tire; The wear of suspension system parts is accelerated; The vehicle will deviate to the side with smaller negative camber.
