PROBLEM TO BE SOLVED: To provide a vehicle body inclination device of a railway vehicle capable of improving ride comfort.SOLUTION: In a vehicle body inclination device 110 of a railway vehicle 100 having an air spring 20 for supporting a vehicle body 50 placed on a bogie 10, a first air flow passage 31 and a second air flow passage 41 for supplying-exhausting air to the air spring 20, a passive adjusting valve and an inclination adjusting valve 40, a first cutoff valve 32 and a second cutoff valve 42, a control device for controlling the first cutoff valve 32 and the second cutoff valve 42 for opening-closing, and a main air reservoir 60, the control device comprises: storage means for storing a map for determining a preceding time (t) of opening-closing control of the first cutoff valve 32 or the second cutoff valve 42, and differential pressure ΔP corresponding to the preceding time (t); and calculation means for calculating the differential pressure between air spring inner pressure P2 being inner pressure of the air spring 20 and main reservoir supply pressure P1 being inner pressure of the main air reservoir 60. The control device uses the preceding time (t) corresponding to the differential pressure ΔP determined in this map, for controlling opening-closing of the first cutoff valve 32 or the second cutoff valve 42.SELECTED DRAWING: Figure 6

    【課題】乗り心地を改善可能な鉄道車両の車体傾斜装置の提供。【解決手段】台車10に載置された車体50を支持する空気バネ20と、空気バネ20に空気を給排気する第1空気流路31及び第2空気流路41と、パッシブ調整弁と傾斜調整弁40と、第1遮断弁32と第2遮断弁42と、第1遮断弁32及び第2遮断弁42を開閉制御する制御装置と、元空気溜60とを備えた鉄道車両100の車体傾斜装置110において、制御装置に、第1遮断弁32または第2遮断弁42の開閉制御の先行時間tと、先行時間tに対応する差圧ΔPを定めたマップを記憶する記憶手段と、空気バネ20の内圧である空気バネ内圧P2と、元空気溜60の内圧である元ダメ供給圧P1との差圧を計算する計算手段と、を備え、制御装置がこのマップに定められる差圧ΔPに対応した先行時間tを、第1遮断弁32または第2遮断弁42の開閉制御に用いる。【選択図】図6
