To provide a highly reliable and highly efficient air suspension system of a vehicle by improving followability of stroke control with respect to pressure fluctuation applied to a liner compressor, and suppressing stroke increase due to a pressure drop, and by collision avoidance of a piston, and increase in a flow rate due to reduced dead volume.SOLUTION: An air suspension system includes: an air suspension which supplies and discharges compressed air and adjusts the length; a compressor body in which a piston reciprocates in a cylinder to compress air; a linear motor causing the piston to reciprocate; a tank which is connected to the air suspension or the compressor body in order to store the compressed air; a solenoid valve which opens and closes the air suspension or the tank; and an inverter which changes power to be supplied to the linear motor according to an opening/closing state of the solenoid valve, and positionally controls the piston.SELECTED DRAWING: Figure 2

    【課題】 リニアコンプレッサにかかる圧力変動に対するストローク制御の追従性を向上し、圧力低下によるストローク増加を抑え、ピストンの衝突防止、及び、死容積低減による流量増加により、高信頼で高効率の車両のエアサスペンションシステムを提供することにある。【解決手段】 圧縮空気を給排して長さを調整するエアサスペンションと、ピストンがシリンダ内を往復運動して空気を圧縮するコンプレッサ本体と、前記ピストンを往復運動させるリニアモータと、前記エアサスペンションまたは前記コンプレッサ本体と接続され、圧縮空気を蓄えるタンクと、前記エアサスペンションまたは前記タンクを開閉する電磁弁と、該電磁弁の開閉状態に応じて前記リニアモータに供給する電力を変更し、前記ピストンを位置制御するインバータと、を具備するエアサスペンションシステム。【選択図】図2
