PROBLEM TO BE SOLVED: To improve both assembling workability and assembling accuracy of a truck in a configuration where a side wall of a truck frame covers a leaf spring from the outside in a vehicle width direction.SOLUTION: A railroad vehicle truck assembling method is provided with: a leaf spring arrangement step of supporting a leaf spring extending in a vehicle longitudinal direction by a pair of axle boxes separately arranged in the vehicle longitudinal direction; a truck frame arrangement step of directly or indirectly placing a truck frame having a side wall in which an opening is formed on the center of the leaf spring in the longitudinal direction from above, and covering the leaf spring with the side wall from the outside in a vehicle width direction; and a measurement step of measuring positional deviation between the leaf spring and the truck frame in the vehicle longitudinal direction through the opening.SELECTED DRAWING: Figure 5
【課題】台車枠の側壁が板バネを車幅方向外側から覆う構成において、台車の組立作業性と組立精度との両方を向上させる。【解決手段】鉄道車両台車の組立方法は、車両長手方向に延びた板バネを車両長手方向に離間して配置された一対の軸箱に支持させる板バネ配置工程と、開口が形成された側壁を有する台車枠を前記板バネの長手方向の中央部に上方から直接的又は間接的に載せ、前記側壁により前記板バネを車幅方向外側から覆う台車枠配置工程と、前記開口を通じて前記板バネと前記台車枠との間の車両長手方向の位置ズレを測定する測定工程と、を備える。【選択図】図5
