The invention discloses an air bag type spring, a rigidity adjusting method and device of the air bag type spring, a suspension system and a vehicle, and the air bag type spring comprises an air bag (310); a plunger (320) connected to the airbag (310); the spring seat (340) is connected with the air bag (310) and is opposite to the plunger (320); and the swing part (330) is rotationally connected with the plunger (320) or the spring seat (340), is positioned outside the air bag (310) and is propped against the air bag (310). The effective inner diameter (dk) of the air bag (310) is changed by rotating the swing piece (330), so that the rigidity of the air bag (310) is changed, and the stability and comfort of the vehicle are both considered.

    一种气囊式弹簧、气囊式弹簧的刚度调节方法及装置、悬架系统、车辆,其中,气囊式弹簧包括:气囊(310);柱塞(320),与气囊(310)连接;弹簧座(340),与气囊(310)连接,与柱塞(320)相对;以及摆动件(330),与柱塞(320)或弹簧座(340)转动连接,位于气囊(310)外且与气囊(310)抵接。通过转动摆动件(330)改变气囊(310)的有效内直径(dk),从而改变其刚度,兼顾车辆的稳定性和舒适性。
