Abstract

PURPOSE:To improve the riding comfort and stability of a vehicle by detecting the road condition for roughness and flatness and controlling supply and dis charge of oil into and from each oil chamber to keep the upper displacement of a spring of a suspension cylinder constant when the vehicle runs on rough road. CONSTITUTION:A wheel 3 is held by a chassis 1 via a suspension cylinder 4. Working oil is fed and discharged from an into the outside parts into and from upper and lower oil chambers 4A and 4B of a piston 4a inside the suspension cylinder 4 via a control valve 6. A control valve 6 is controlled by a control unit 8. In such equipment, the control unit 8 receives detected signals given from a road surface sensor 9 and stroke sensor 5. When a vehicle runs on rough road 2, supply and discharge of working oil is controlled to keep the upper displacement of the spring of the suspension cylinder 4 constant.
