PROBLEM TO BE SOLVED: To provide a compressed air supply device capable of supplying compressed air without the need for a dedicated power source.SOLUTION: A compressed air supply device comprises: an air compressor 110 which is fitted outside in a crosstie direction (vehicle width direction) of an axle box of a truck frame such that an input axle is substantially concentric with a wheel axle 30 provided with a wheel, and also driven by rotation of the wheel axle to compress air; and an air reservoir 130 which reserves the air compressed by the air compressor, a clutch being switched between a connection state and a disconnection state according to internal pressure of the air reservoir 130 and a brake operation state of a train.SELECTED DRAWING: Figure 2
【課題】専用の動力源を必要とすることなく圧縮空気の供給が可能な圧縮空気供給装置を提供する。【解決手段】圧縮空気供給装置を、入力軸が車輪が設けられた輪軸30と実質的に同心となるように、台車枠の軸箱のまくらぎ方向(車幅方向)外側に取り付けられ、輪軸の回転によって駆動され空気を圧縮する空気圧縮機110と、空気圧縮機が圧縮した空気が貯留される空気だめ130とを備え、空気だめ130の内圧、及び、列車のブレーキ作動状態に応じて、クラッチの接続状態、切断状態を切り替える構成とする。【選択図】図2
