See figure for camber adjustment of front and rear wheels. Generally speaking, how much curvature is appropriate.

The camber angle is generally between 1-2 degrees. The so-called camber angle refers to the angle between the plane where the wheel is located and the vertical plane after the wheel is installed. When the tire is Zhang Kaicheng-shaped, it is called negative camber, while when the tire is Zhang Kaicheng-shaped, it is called positive camber. Sports cars or racing cars often use negative inclination.

The camber angle of the rear wheel can be adjusted by the eccentric screw at one end of the upper cantilever, which is specially used to adjust the camber angle. If the cantilever on the vehicle model cannot be adjusted without eccentric screws, it can be replaced by an adjustable arm, which has a wide adjustment range and is simple to operate. You can see the following picture:

For the front wheel positioning of independent suspension, the camber angle of the wheel is adjusted by adding an adjusting gasket between the upper arm shaft and the fixing frame, so the adjusting gasket can be increased or decreased as needed.

The camber of the front wheel has a direct impact on the cornering performance of the car. On the one hand, it can make the wheels roll and slide near the vertical road surface, reduce steering resistance and improve the portability of front wheel steering control. On the other hand, the load of the bearing and its locking nut is reduced, the service life is prolonged and the steering safety is improved. In order to prevent the wheel from being easily deformed when it is vertical to the ground and fully loaded, which may lead to the upper part of the wheel inclining inward, resulting in the damage of the tire joint, the vehicle is generally offset by an outer octagonal angle, about 65438 0 degrees.

Influence of incorrect camber angle on vehicles.

1, excessive positive camber will cause unilateral wear on the outside of the tire; Accelerated wear of suspension system parts; The vehicle will lean to the side with larger positive camber angle.

2. Excessive negative camber will cause unilateral wear on the inner side of the tire; Accelerated wear of suspension system parts; The vehicle will lean to the side with smaller negative camber.
