Description
Technical Field
The utility model relates to the technical field of automobile part detection, in particular to a camber angle measuring device of a front axle assembly.
Background
The camber angle refers to the angle alpha between the plane in which the wheel is located and the vertical plane. The tire exhibits a "splay" when open, referred to as negative camber, and a "V" when open, referred to as positive camber. The function of the device is to improve the safety of the wheels during operation. Due to the assembly clearances between the kingpin and the bushing, at the hub and bearings, etc., these clearances affect the proper functioning of the wheel to a different extent. When the wheel has a certain camber angle, the central line of the tire and the ground are intersected at a point A, the axis of the steering main pin and the road surface are intersected at a point B, and the distance between the two points is called offset.
Since the wheel rotates around the center and radius of the kingpin axis during steering, a large moment is generated around the kingpin due to the rolling resistance of the tire, and the steering force is increased. The greater the deflection, the greater the torque generated. When having a camber angle, the amount of offset can be reduced, so the steering force can be reduced.
When the wheel is camber, a component force applied to the spindle is generated under the action of vertical load, so that the wheel is inwards pressed on the bearing to prevent the wheel from being thrown off. When the camber angle is unsatisfactory, the adverse consequences include: the wear of the ball joint and the wheel bearing is increased (the wear of the inner bearing of the negative camber angle is increased, and the wear of the outer bearing of the positive camber angle is increased). When the camber angle is too large or is unequal to the left and right, the vehicle is also caused to deviate to the side with larger positive camber angle. Therefore, the camber angle of the front axle assembly needs to be strictly controlled when the front axle assembly leaves a factory; in the prior art, a device capable of rapidly detecting the camber angle of a front axle assembly is lacking.
