PROBLEM TO BE SOLVED: To make it possible to easily perform a work for keeping a wheel base of a pair of wheel shafts as a design value when assembling a truck.SOLUTION: A method for assembling a railroad vehicle truck comprises: a positioning process in which a wheel base fixture, which extends in a vehicle longitudinal direction, is engaged with a pair of shaft box devices which are so located as to be separated from each other in the vehicle longitudinal direction, whereby the pair of shaft box devices are positioned so that a wheel base of a pair of wheel shafts, which are respectively supported on the pair of shaft box devices, becomes a prescribed design value; a leaf spring arrangement process in which a leaf spring, which extends in the vehicle longitudinal direction, is supported by the pair of shaft box devices; and a truck frame arrangement process in which a truck frame is supported on a midship part of the leaf spring in a longer direction, and the truck frame is connected to the pair of shaft box devices.SELECTED DRAWING: Figure 4
【課題】台車組立時に一対の輪軸の軸距を設計値通りに保つ作業を簡便にする。【解決手段】鉄道車両台車の組立方法は、車両長手方向に離間して配置された一対の軸箱装置に車両長手方向に延びた軸距固定治具を係止することで、前記一対の軸箱装置に夫々支持された一対の輪軸の軸距が所定の設計値となるように前記一対の軸箱装置を位置決めする位置決め工程と、前記一対の軸箱装置に車両長手方向に延びた板バネを支持させる板バネ配置工程と、前記板バネの長手方向の中央部に台車枠を支持させ、前記一対の軸箱装置に前記台車枠を連結する台車枠配置工程と、を備える。【選択図】図4
