What is the Principle of Wheel Alignment?

[JasonDella]

Wheel alignment is used to measure the distance that the wheels rotate forward or deviate from the vehicle's centerline. Here is the relevant information: 1. Camber: Camber is the angle of the tire relative to the vertical reference line. When the top of a wheel tilts outward, it is said to have positive camber. When the top of a wheel tilts inward, it is said to have negative camber. The camber setting can affect vehicle steering control and tire wear. 2. Caster: Caster is the angle of the steering axis tilting forward or backward. Caster is measured by observing the angle between the steering axis and the vertical line from the side view. 3. Toe: The function of toe is to compensate for the tendency of the tires to roll inward or outward due to camber and road resistance, ensuring the vehicle's straight-line stability.
