PROBLEM TO BE SOLVED: To reduce variation in wheel weight due to a pressure difference of an air spring in curve passage of a railroad vehicle.SOLUTION: The present invention relates to a wheel weight adjusting device 10 which comprises a vehicle body 2, first and second carriages 3A, 3B, first to fourth air springs 4A, 4B and 5A, 5B, an air reservoir 6, and first to fourth automatic height adjusting valves 7A, 7B and 8A, 8B. The wheel weight adjusting device limits an air feeding/exhausting operation of at least one of the first to fourth automatic height adjusting valves in curve passage of a railroad vehicle so as to suppress a pressure difference between at least two of the first to fourth air springs from increasing.SELECTED DRAWING: Figure 2
【課題】鉄道車両の曲線通過時における空気バネの圧力差による輪重変動を低減する。【解決手段】車体2と、第1及び第2台車3A,3Bと、第1〜第4空気バネ4A,4B,5A,5Bと、空気溜め6と、第1〜第4自動高さ調整弁7A,7B,8A,8Bと、輪重調整装置10を備える。輪重調整装置は、鉄道車両の曲線通過時において、第1〜第4空気バネのうち少なくとも2つの空気バネ間の圧力差の増加を抑制するように、第1〜第4自動高さ調整弁のうち少なくとも1つの自動高さ調整弁の給排気動作を制限する。【選択図】図2
