PROBLEM TO BE SOLVED: To provide a truck for a railway vehicle which has a simple configuration and which can achieve both of travel stability and curve passage performance.SOLUTION: A truck (1) comprises a truck frame (2) having left and right side beams (2A, 2B), axle boxes (5A to 5D) which are located on left and right sides of front and rear respective wheels shafts (3A, 3B), and axle box suspensions (6A to 6D) which elastically support between respective axle boxes (5A to 5D) and the truck frame (2). The axle box support suspension (6A to 6D) includes: a fitting part (5Aa to 5Da) which projects from each axle box (5A to 5D) along a cross direction; a rubber (10A to 10D) which has a space (10Ab to 10Db), and combines the fitting part (5Aa to 5Da) and the side beam (2A, 2B) with each other; a pipeline (40A, 40B) which connects the spaces (10Ab to 10Db) of a set of rubbers (10A to 10D), which are located diagonally opposite to each other, to each other; and a liquid which is charged into the space (10Ab to 10Db) and the pipeline (40A, 40B) connected to each other.SELECTED DRAWING: Figure 1
【課題】簡素な構成で走行安定性と曲線通過性を両立できる鉄道車両用台車を提供する。【解決手段】台車(1)は、左右に側はり(2A、2B)を有する台車枠(2)と、前後の各輪軸(3A、3B)の左右に配置される軸箱(5A〜5D)と、各軸箱(5A〜5D)と台車枠(2)との間を弾性的に支持する軸箱支持装置(6A〜6D)と、を備える。軸箱支持装置(6A〜6D)は、各軸箱(5A〜5D)から前後方向に沿って突出する取付け部(5Aa〜5Da)と、内部に空間(10Ab〜10Db)を有し、取付け部(5Aa〜5Da)と側はり(2A、2B)とを結合するゴム(10A〜10D)と、互いに斜向いに配置されたゴム(10A〜10D)の組の空間(10Ab〜10Db)同士を連結する配管(40A、40B)と、互いに連結された空間(10Ab〜10Db)及び配管(40A、40B)に充填された液体と、を含む。【選択図】図1
