Figure 10. Definition of Vehicle Heading. The steering angle is defined as the angle between the front of the vehicle and the steered wheel direction as shown in Figure 11. The steering system has a maximum (minimum) steering angle of +0.52359878 (-0.52359878) radians or +30 (-30) degree. Figure 11.
Steering axis inclination is the number of degrees that a line drawn through the upper and lower ball joints (or strut and lower ball joint) and viewed from the front is tilted to the left or the right. This, in combination with caster, is responsible for the directional stability and self-centering of the steering.ositive caster means that the top of the upper ball joint (or strut) is tilted toward the rear of the vehicle, and negative caster means that it is tilted toward the front. A vehicle with a slightly positive caster setting will have its lower ball joint pivot slightly ahead of the tire's center.
