Non-contact 4-wheel alignerMain angles of positioning:

Camber

Definition: The angle between the centerline of the tire and the vertical line in the air when viewed from the front of the car is called the camber angle. The wheel tilts outwards for positive and the wheel tilts inwards for negative.

Function: To prevent the suspension from deforming and causing the wheels to tilt inward when the vehicle is fully loaded, to avoid partial wear of the tires and to reduce the load on the hub bearings. To reduce the distance from the grounding point of the front wheel longitudinal rotation plane to the intersection of the extended line of the kingpin centerline and the air, so as to make steering easier.

Kingpin inclination angle

Definition: When viewed from the front of the car, the angle between the centerline of the steering axis and the vertical line in the air is called the kingpin inclination angle. The kingpin inclination is positive, and the kingpin outward inclination is negative.

Function: Makes steering easier and generates a return torque after the front wheels turn.

Caster Angle

Definition: When viewed from the side of a car, the angle between the centerline of the steering axis and the vertical line in the air is called the kingpin caster angle. The kingpin tilts backwards for a positive angle and the kingpin tilts forward for a negative angle.

Function: When the steering wheel is slightly deflected by an external force during driving, the castor will generate a torque in the opposite direction of the wheel, causing the wheel to automatically return to the correct position, thus ensuring the stability of the vehicle's straight-line driving.
