To provide a wheel weight variation suppression device or the like capable of suppressing wheel weight variation caused by an orbit plane property displacement using information which can be obtained on a vehicle.SOLUTION: There is provided a wheel weight variation suppression device for a railway vehicle which comprises: first rank bogie and second rank bogie 100F, 100R provided on a lower part of a vehicle body 10; first and second air springs 170FL, 170FR provided between the first rank bogie and the vehicle body; third and fourth air springs 170RL, 170RR provided between the second rank bogie and the vehicle body; and a feeding/discharging unit 200 for feeding air and discharging air from the air springs. The wheel weight variation suppression device comprises: an orbit plane property displacement detection part which is configured to detect upper heights of the first and fourth air springs to a lower part, and on the basis of a diagonal differential component between the upper heights of the first and fourth air springs and upper heights of the second and third air springs, detect an orbit plane property displacement, and when the orbit plane property displacement is detected, air is fed to the pair of air springs on which a length thereof is relatively extended.SELECTED DRAWING: Figure 12

    【課題】車上で取得可能な情報を用いて軌道平面性変位に起因する輪重変動を抑制した輪重変動抑制装置等を提供する。【解決手段】車体10の下部に設けられた1位、2位台車100F,100Rと、1位台車と車体との間に配置された第1、第2の空気ばね170FL,170FRと、2位台車と車体との間に配置された第3、第4の空気ばね170RL,170RRと、空気ばねに給排気を行う給排気装置200とを備える鉄道車両の輪重変動抑制装置を、第1乃至第4の空気ばねの下部に対する上部高さをそれぞれ検出し、第1、第4の空気ばねの上部高さと、第2、第3の空気ばねの上部高さとの対角差成分に基づいて軌道平面性変位を検出する軌道平面性変位検出部を有し、軌道平面性変位が検出された際に、長さが相対的に伸長した側の対の空気ばねに給気を行う構成とする。【選択図】図12
