Yes, any car has a certain negative inclination angle.
Camber: The wheel camber angle refers to the outward tilt of the end face of the wheel after installation, that is, the angle between the plane where the wheel is located and the longitudinal vertical plane. When the tire opens in an "eight" shape, it is called negative camber, and when it opens in a "V" shape, it is called positive camber. Its function is to improve the safety of wheel operation.
Since there are assembly gaps between the kingpin and bushing, wheel hub and bearing, etc., 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 with the ground at point A, and the steering kingpin axis intersects with the road surface at point B. The distance between these two points is called the offset. Since the wheels rotate around the center and radius of the kingpin axis when turning, a large torque will be generated around the steering kingpin due to the rolling resistance of the tires, thereby increasing the steering force. The greater the deflection, the greater the torque generated. When there is a camber angle, the offset can be reduced, so the steering force can be reduced.
In addition, when the wheel is cambered, a component force exerted on the spindle will be generated under the action of the vertical load, causing the wheel to press inward on the bearing to prevent the wheel from spinning off. When the wheel camber angle does not meet the requirements, the adverse consequences include: increased wear of the ball hinge and wheel bearings (increased wear of the inner bearing with negative camber angle; increased wear of the outer bearing with positive camber angle). When the camber angle is too large, or is unequal from left to right, it will also cause the vehicle to deviate to the side with the larger positive camber angle.
