In a double wishbone type wheel suspension system comprising an upper A-arm and a lower A-arm, a toe control link is additionally provided between the vehicle body and a forward part of the knuckle. In particular, the pivotal attachment of the toe control link to the vehicle body is located below the plane defined by the lower A-arm, and the toe control link is located generally ahead of the spindle of the wheel. Therefore, the toe control link can be arranged close to the road contact surface of the wheel so that the resistance of the wheel against the side force which tends to tilt the wheel in the direction to change the camber angle can be increased so that a high camber rigidity can be achieved. This improves the anti-squat property of the vehicle, and improves the lateral stability of the vehicle when traveling over irregular road surfaces as well as when making turns. Also, because the toe control ink is placed ahead of the spindle, it is possible to maximize the distance between the control link and the king pin axis, which typically has a negative caster angle and a negative caster trail. Therefore, a highly controllable toe compliance can be produced so that a suitable side-force steer-in property can be achieved while maintaining a sufficient camber rigidity.
