PROBLEM TO BE SOLVED: To provide an air spring device capable of easily adjusting the height of a vehicle body without requiring a large-scale facility.SOLUTION: There are provided a first air spring 2 installed between a vehicle body 21 and a carriage frame 24 of a railway vehicle 19, and a lifting device 3 for lifting and lowering the first air spring 2. The lifting device 3 includes a second air spring 17 provided separately from the first air spring 2 and it elevates the first air spring 2 by expanding the second air spring 17 to create a gap into which a shim 30 for height adjustment of the vehicle body can be inserted between the first air spring 2 and the carriage 24, and also it lowers the first air spring 2 by contracting the second air spring 17.SELECTED DRAWING: Figure 3
【課題】大がかりな設備を必要とせず、車体高さ調整を容易に行なうことが可能な空気ばね装置を提供することを目的とする。【解決手段】鉄道車両19の車体21と台車枠24の間に設置される第一空気ばね2と、第一空気ばね2を昇降させる昇降装置3とを備え、昇降装置3は、第一空気ばね2とは別に独立して設けられた第二空気ばね17を備え、第二空気ばね17を膨張させることによって第一空気ばね2を上昇させ、第一空気ばね2と台車24との間に車体高さ調整用のシム30を挿入可能な隙間を生じさせるとともに、第二空気ばね17を収縮させることによって第一空気ばね2を下降させるようにする。【選択図】図3
