ABSTRACT:
In a suspension system, a trailing arm and a knuckle are interconnected by a first rubber bush joint located in front of and below an axle, a second rubber bush joint located above the axle, and a third rubber bush joint located in back of and below the axle. Each of the rubber bush joints has a characteristic such that it is soft in a direction of an axis thereof and hard in a direction perpendicular to the axis in order to ensure a longitudinal compliance. The rigidity of the first rubber bush joint in the direction perpendicular to its axis is set lower than that of the third rubber bush joint in the direction perpendicular to its axis in order to produce inward towing of the outer wheel as viewed in the turning direction. Rear sides of the axes of the second and third rubber bush joints are inclined outwardly of the vehicle body in order to generate inward towing during braking. Thus, it is possible to insure a high longitudinal compliance to provide an excellent stability during turning and during braking of the vehicle.
