PROBLEM TO BE SOLVED: To suppress increase in the number of compressors or their capacity while using a pneumatic damper in a secondary suspension of a railway vehicle.SOLUTION: A secondary suspension device for a railway vehicle comprises: a pneumatic damper which has a lower member, an upper member displaceable perpendicularly with respect to the lower member, and a diaphragm connecting the lower member with the upper member to form a compressed-air space; and an auxiliary spring which is compressed and deformed in coordination with mutual perpendicular approach and displacement of the lower member and the upper member within an elastic displacement range of the pneumatic damper.SELECTED DRAWING: Figure 2

    【課題】鉄道車両の二次サスペンションに空気バネを用いながらも、コンプレッサの増加又は大容量化を防止する。【解決手段】鉄道車両の二次サスペンション装置は、下部材と、前記下部材に対して鉛直方向に変位可能な上部材と、前記下部材と前記上部材とを繋いで圧縮空気空間を形成するダイヤフラムとを有する空気バネと、前記空気バネの弾性変形範囲内で前記下部材と前記上部材とが互いに鉛直方向に近接変位するのに連動して圧縮変形する補助バネと、を備える。【選択図】図2
