Abstract: A suspension device in a motor vehicle has at least one component separate from a damper and to which vertical movement of a road wheel can be transmitted. The component comprises a resilient member supported on a vehicle body at a portion spaced from another portion operatively coupled to the road wheel, for giving vertical resiliency to the road wheel. The suspension device also has a counteracting load mechanism for applying a counteracting load which is variable dependent on an amount of flexing of a section of the component caused by vertical movement of the road wheel. The suspension device further includes a vehicle height adjusting mechanism operatively coupled to the counteracting load means for varying a static counteracting load of the counteracting load mechanism when the motor vehicle is at rest, to thereby vertically displace the section of the component for adjusting the height of the motor vehicle.
