PROBLEM TO BE SOLVED: To provide an air spring capable of improving a curved rail travel performance of a railroad vehicle by including a structure of the air spring which allows displacement relative to a car body or a truck frame, for a reduced air spring reactive force, resulting in reduced lateral pressure.SOLUTION: An air spring is provided with an upper surface part which faces a car body of a railroad vehicle and a lower surface part which faces a truck frame, connecting the car body to the truck frame. It includes a position displacement means in which either the upper surface part or the lower surface part is fitted with the air spring along an advancing direction of the railroad vehicle, for displacement.SELECTED DRAWING: Figure 1
【課題】空気ばねが車体又は台車枠に対して変位を許容する構造をもつことで、空気ばね反力を減少させて横圧を低減でき、これによって、鉄道車両の曲線通過性能を向上させることができる空気ばねを提供する。【解決手段】鉄道車両の車体と対向する上面部と、台車枠と対向する下面部とを備え、前記車体と前記台車枠を連結する空気ばねにおいて、前記上面部又は前記下面部のいずれか一方に、前記空気ばねを前記鉄道車両の進行方向に沿って変位可能に取り付ける位置変位手段を備える。【選択図】図1
