Abstract
In a multi-link rear suspension (A) in which a wheel support (11) is connected to a vehicle body through five links (6-10) and vehicle body side ends of the links are provided with rubber bushes (26), respectively, the lower end of a damping device (14) formed by coaxially arranging a coil spring (12) and a damper (13) is pivoted to a portion of the wheel support (11) located toward the inside of the vehicle body so that the vertical reaction force of the damping device (14) produces a moment Mn toward negative camber on a rear wheel (2). The moment Mn is set to be always larger than a moment Mp toward positive camber produced by a side force on the outside rear wheel (2) during vehicle cornering until limit maneuvering conditions of the outside rear wheel due to the side force are reached. The damping device (14) is disposed with respect to a suppositive king pin axle K so that the vertical reaction force thereof produces a moment toward toe-in on the rear wheel (2). In this manner, the multi-link suspension provides a sharp driving feeling applicable even for a sports car while maintaining a good ride through the involvement of the rubber bushes (26).
