To obtain a suspension device which achieves enhancement of ride feeling and damping property without using a vehicle height sensor.SOLUTION: A suspension device 10 comprises a damper gear 12 which causes damping force between a vehicle body 2 and wheels 3, and a control part 40 which controls damping force generated to the damper gear 12. The control part 40 controls damping force generated to a damping part so that, when a speed region of movement speed is divided into three regions of a low-speed region, an intermediate speed region, and a high-speed region in a lower limit boundary line Q drawn by a lower limit of the damping force in a relationship between relative movement speed of the vehicle body 2 and the wheels 3 and the damping force, a rate of a change in the damping force to a change in the movement speed in the intermediate speed region becomes larger than a rate of a change in the damping force to a change in the movement speed in other speed regions.SELECTED DRAWING: Figure 3
【課題】車高センサを用いることなく、乗り心地及び制振性の向上を図れるサスペンション装置を得る。【解決手段】サスペンション装置10は、車体2と車輪3との間で減衰力を生じるダンパ装置12と、ダンパ装置12に生じる減衰力を制御する制御部40とを備える。制御部40は、車体2と車輪3との相対的な移動速度と前記減衰力との関係で該減衰力の下限値によって描かれる下限境界線Qにおいて、前記移動速度の速度領域を低速度領域、中速度領域及び高速度領域の3つの領域に分けた場合に、前記中速度領域における前記移動速度の変化に対する減衰力の変化の割合が、他の速度領域における前記移動速度の変化に対する減衰力の変化の割合よりも大きくなるように、前記減衰部に生じる減衰力を制御する。【選択図】図3
