Abstract
A pair of upper and lower radius rods are connected at their rear ends to upper and lower portions of a swingable link system which includes a knuckle and upper and lower control arms, and have their front ends interconnected and pivotally connected to a vehicle body through an elastic support member for vertical swinging movement, and an included angle between two straight lines connecting the pivoted point and respective rear end of the radius rods is set to be an acute angle. This enables application of a force to the elastic support member between the radius rods and the vehicle body to be distinguished from (a) when a braking force has been applied to the wheel and (b) when the longitudinal load has been applied to a central portion of the wheel. Thus, it is possible to provide a larger longitudinal compliance while insuring a caster rigidity of the suspension system, thereby satisfying both (a) a straight advancing property during braking and (b) a shock absorbing property during travelling on a bad road surface. Moreover, it is possible to improve the riding comfort during braking.
