PROBLEM TO BE SOLVED: To provide a link-type steering bogie having a high design flexibility, in which a link mechanism and other components, etc. hardly interfere with each other.SOLUTION: A steering bogie comprises a link mechanism which is in conjunction with the rotation of the bogie frame with respect to the rolling stock body, and which steers at least one of wheel shafts by displacing an axle box via an axle beam. The link mechanism includes a lever member arranged closer to the axle box than the center of the bogie frame in a rolling stock width direction, and a connection link closer to the center of the bogie frame in the rolling stock longitudinal direction. The connection link connects a bolster beam or the rolling stock body and the lever member, and the lever member rotates around a fulcrum part connected to the connection link and the axle beam, and supported by the bogie frame to steer the wheel shafts.SELECTED DRAWING: Figure 1
【課題】リンク機構と他の構成部品等が干渉しにくく、設計自由度が高いリンク式の操舵台車を提供する。【解決手段】操舵台車は、車体に対する台車枠の回動に連動し、軸梁を介して軸箱を変位させることで少なくとも一方の輪軸を操舵するリンク機構を備え、リンク機構は、台車枠の車両長手方向中央よりも軸箱寄りに配置されるテコ部材と、テコ部材よりも台車枠の車両長手方向中央寄りに配置される連結リンクと、を有し、連結リンクは、枕梁又は車体とテコ部材とを連結し、テコ部材は、連結リンク及び軸梁に連結されて、台車枠に支持された支点部を中心に回動して輪軸を操舵する。【選択図】図1
