四轮定位相关知识四轮定位的重要性（The importance of four-wheel positioning related knowledge four-wheel positioning） The importance of four-wheel positioning related knowledge four-wheel positioning Four-wheel orientation Angle is found in suspension system and the activities of the relative Angle between the parts, keep the correct Angle of four-wheel positioning can ensure the vehicles straight into sex and maneuverability, improved the vehicles steering and ensures the resilience of steering system, to avoid improper bearing stress and damage and loss of accuracy. Make sure the tire is close to the ground, reduce the tires wear and tear, and ensure the stability of the turn. The significance of four-wheel positioning The main positioning angles of the car suspension system include: Camber, rear tilt Angle (Castor), beam Angle (Toe), internal tilt (K.P.I.), and Toe - out on Turn, etc. The meaning is described as follows: 1. External inclination (Camber) : defines the Angle between the center line of the tire and the vertical line from the front of the car, and is positive and negative to the outside. The difference of the Angle can change the contact point and the force point of the tire, which directly affects the grip and abrasion of the tire. It also changes the force distribution on the axle to avoid abnormal wear. In addition, the existence of the outer dip Angle can be used to offset the Angle changes caused by the deformation of the suspension system and the surface clearance of the suspension system. The existence of the camber Angle can also affect the direction of the car, just as motorcycle available tilting body to turn, so the left and right wheel camber Angle must be equal, under the balance of power is not a shadow to the car straight into sex, again with beam Angle (Toe), improve the straight into the stability and avoid uneven tire consumption. Increase the negative outer tilt Angle needs to cooperate to increase the Toe - out; Increasing the positive external inc
