Infection of caster angle
Major function of caster angle is to ensure vehicle to run in direction of dead ahead. In case that caster angle is
positive value, internal side of vehicle should step down, while chassis should rise during rotation of front wheel;
in case that caster angle of two wheel are uniform, vehicle should return to direction of dead ahead after steered.
Adding degree of caster angle should increase stability of steering wheel, and increase steering strength; reducing
degree of caster angle should decrease stability of steering wheel, and reduce steering strength. Degree of caster
angle should not effect abrasion of tire; it is used to stabilize running direction of vehicle and return to right
direction automatically after steered. If the vehicle is equipped with traditional and mechanical steering device,
for smoothing the way of steering, the caster angle should be very small, even incline to a negative value. If
vehicle is equipped with power steering device, for increasing feeling of driver, caster angle is set to a bigger
positive value generally, which should increase steering strength, and increase stability of straightline driving.
