Abstract
A double-wishbone type suspension system includes a hub carrier for rotatably supporting a front wheel of a vehicle, and upper and lower link devices for connecting upper and lower ends of the hub carrier to a vehicle body, respectively. The upper link device is connected to the vehicle body and the hub carrier at first and second connecting points, respectively. The lower link device includes a link element to be applied with a steering force such that the hub carrier is rotated about a kingpin axis which passes a point between the upper and lower ends of the hub carrier. The suspension system has a novel geometrical arrangement such that, in the case of a front wheel which is situated on outer side with reference to a cornering center, the second connecting point is caused during a steering operation to move along an arcuate path about the first connecting point so that the kingpin axis is tilted inwardly. During a steering operation, the front wheel has a camber characteristic which exhibits a negative camber tendency while minimizing a force component tending to lift the front wheel to ensure a natural steering feel.
