PURPOSE:To achieve a greater operational stability during the cornering by arranging a ball joint in the second quadrant of the horizontal-vertical coordinate with the rear wheel center as reference as viewed from the left side of a body and rubber bushes in the first and fourth quadrants. CONSTITUTION:When a lateral force S works on the ground contact G, a tire is caused to rotate in the toe-in direction about the line running between a ball joint 1 and a rubber bush 3 in the fourth quadrant. A braking force B causes the tire to the displaced in the toe-in direction about the axis L due to the offset G - at the ground contact G. At the same time, a toe-in displacement takes place likewise due to an effect of guiding the counterclockwise rotation about the axis M in the toe-in direction depending on the tilting of bushes 3 and 4 overcoming the tendency to toe out which results from an offset W+ at the wheel center W by the braking force E. With respect to a driving force K, the tire is caused to be displaced in the toe-in direction about the axis L resulting from an offset W+ at the center. Here, it is desirable to provide a stopper on either the bush 3 or 4 to regulate the clockwise rotation about the axis M. |
