Abstract

PURPOSE:To contrive to improve the running stability by a simple structure wherein the mounting location of a spring unit, which functions as a damper, is provided so that its spring reaction is applied to a wheel hub at the bumping so as to toe-in a wheel. CONSTITUTION:A spring unit 8 is mounted to the wheel hub 2 at the back of the virtual vertical rotation axis P of the wheel hub 2 in an path outwardly and downwardly inclined from a car body side. Consequently, when the wheel 1 bumps, a semi-trailing arm 3 pivots about bushings 4 connected to a car body, resulting in oscillating the hub 2 connected to the arm 3 at its rear end together with the pivoting motion of the arm 3. In this case, an outward and downward spring reaction force is generated in a spring unit 8 as the reaction force of bumping load in order to apply at the back of the virtual rotation axis P. Accordingly, the hub 2 is rotatingly displaced about the axis P toward the direction to toe-in by means of the outwardly horizontal component of spring reaction force, resulting in changing the wheel to toe-in and consequently improving the running stability.

As disclosed in the specification and drawings, there is a wheel support member that rotatably supports the wheel, and one end of each wheel support member is swingably supported on the vehicle body, and the other end is connected to the wheel support member via an elastic member. The two front lateral links supported at the front part and extending parallel to the left and right direction of the vehicle body are equipped with a radius link that restricts the movement of the wheel support member in the front and rear direction of the vehicle body. and the rear lateral link so that the inclination angles are different from each other, so that when the wheel bumps, the connection between the front lateral link and the wheel support member is positioned closer to the inside of the vehicle than the connection between the rear lateral link and the wheel support member. It has been proposed to change the toe-in of the wheel by displacing the wheel largely in the opposite direction.
