PROBLEM TO BE SOLVED: To provide a pneumatic spring system of a railway vehicle which can change the air capacity without using a variable orifice.SOLUTION: A pneumatic spring system of a railway vehicle 100 includes: a pneumatic spring 20 provided in the railway vehicle 100; and auxiliary air chambers 40 communicating with the pneumatic spring 20 through an orifice. The pneumatic spring system further includes: a control device 150 which controls a height of the pneumatic spring 20; a memory storage which stores control timing; and the auxiliary air chambers 40. The pneumatic spring 20 is connected with a second auxiliary air chamber 42 of the auxiliary air chambers 40 through a cutoff valve 25, and the cutoff valve 25 is controlled by the control device 150 so that a volume ratio of the pneumatic spring 20 to the auxiliary air chambers 40 is changed.SELECTED DRAWING: Figure 3

    【課題】可変オリフィスを用いずに空気容量の変更が可能な鉄道車両の空気ばねシステムの提供。【解決手段】鉄道車両100に備えられた空気ばね20と、空気ばね20にオリフィスを介して連通する補助空気室40と、を備える鉄道車両100の空気ばねシステムにおいて、空気ばね20の高さの制御を行う制御装置150と、制御タイミングを記憶した記憶装置と、複数の補助空気室40とを備え、空気ばね20と補助空気室40のうち第2補助空気室42は遮断弁25を介して接続され、空気ばね20と補助空気室40との容積比が変化するように、制御装置150によって遮断弁25を制御する。【選択図】図3
