Role of camber
The role of the camber is to improve the safety of the wheel when it is working. Due to the assembly gap between the kingpin and the bushing, the hub and the bearing, these gaps affect the normal operation of the wheel to varying degrees. When the wheel has a certain camber angle, the center line of the tire intersects the ground at point A, and the steering kingpin axis intersects the road surface at point B. The distance between these two points is called the offset. Since the wheel rotates around the center and radius of the main pin axis when the wheel is turned, a large torque is generated around the steering kingpin due to the rolling resistance of the tire, and the steering force is increased. The larger the offset, the greater the torque generated. When the camber angle is provided, the offset can be reduced, so that the steering force can be reduced. In addition, when the wheel is cambered, a component force applied to the mandrel is generated under the action of the vertical load, so that the wheel is pressed inward on the bearing to prevent the wheel from being detached.
When the wheel camber angle does not meet the requirements, the adverse consequences include: increased wear of the ball joint and the wheel bearing (increase in bearing wear in the negative camber angle; increased wear on the outer camber outer bearing). When the camber angle is too large, or the left and right are not equal, it will also cause the vehicle to go to the side with the larger camber angle.
