PROBLEM TO BE SOLVED: To enable the reduction of labor and time required for measurement by improving measurement efficiency with a simple structure.SOLUTION: A wheel inner surface distance measurement device 1 for measuring an inner surface distance of wheels of a railway vehicle comprises: a horizontal guide rail 5 for placing a wheel 2 thereon and supporting a traveling rail 3 movably in a track gauge direction X; a load lateral pressure part 6 for applying lateral pressure in the track gauge direction X to the wheel 2; a wheel displacement measurement part 7 for measuring the displacement in the track gauge direction X of the wheel 2; a load lateral pressure measurement part 8 for measuring load lateral pressure applied in the track gauge direction X of the wheel 2; and a wheel pressing part 4 for holding the wheel 2 on the traveling rail 3 in the track gauge direction X. A support base 41 comprising the traveling rail 3 is provided in the wheel pressing part 4. The load lateral pressure part 6 presses the support base 41 movably along the horizontal guide rail 5 toward a track gauge outer side X2 and a track gauge inner side X1.
【課題】簡単な構造で測定効率を向上させることで、測定にかかる手間や時間を短縮することができる。【解決手段】車輪2を載せるとともに、走行レール3を軌間方向Xに移動自在に支持する横引きガイドレール5と、車輪2に対して軌間方向Xの横圧を付与する負荷横圧部6と、車輪2の軌間方向Xの変位を測定する車輪変位測定部7と、車輪2の軌間方向Xにかかる負荷横圧を測定する負荷横圧測定部8と、走行レール3上の車輪2を軌間方向Xに挟持する車輪押え部4とを備え、車輪押え部4には、走行レール3を備えた支持台41が設けられ、負荷横圧部6は、支持台41を横引きガイドレール5に沿って軌間外側X2及び軌間内側X1に向けて移動自在に押圧する構成により、鉄道車両の車輪の内面距離を測定する車輪内面距離測定装置1を提供する。【選択図】図1
