How does positive caster provide for increased steering wheel return force?
What will be an ideal response?
With positive caster, the front spindles move through an arc. As a front wheel turns outward, the spindle moves downward in an arc. Since the tire is resting on the road surface, it cannot move downward. Thus, the suspension must move upward under this condition. When the driver returns the steering wheel to the straight-ahead position, gravity forces the vehicle weight to its lowest position, which helps to return the steering wheel to the straight-ahead position.
