END BEAM STRUCTURE OF RAILWAY VEHICLE END UNDERFRAME

To provide an end beam structure of a railway vehicle end underframe which can reliably functionalize an impact absorption member.SOLUTION: An end beam structure of a railway vehicle end underframe having an impact absorption mechanism 200 provided on a connection part of plural railway vehicles 10 to be connected, in which the impact absorption mechanism 200 comprises a first end beam member 140, a second end beam member 150, and an impact absorption beam 160 which are provided at an end part of an underframe 100 of the railway vehicle 10. The first end beam member 140 is provided at one end of the railway vehicle 10, the second end beam member 150 is provided at the other end of the railway vehicle 10, and front faces of these end beam members are so positioned as to face each other. In the first end beam member 140, a hollow extrusion square timber made of an aluminum alloy is used in such a manner that two square timbers are overlapped, and on a side of the first end beam member facing the second end beam member 150, a lag prevention face 141 having a protrusion.SELECTED DRAWING: Figure 4 【課題】衝撃吸収部材を確実に機能させる事ができる鉄道車両端台枠の端梁構造の提供。【解決手段】複数連結される鉄道車両１０の連結部に備えられる衝撃吸収機構２００を有する鉄道車両端台枠の端梁構造において、衝撃吸収機構２００は、鉄道車両１０の台枠１００端部に備えられる、第１端梁部材１４０と第２端梁部材１５０と衝撃吸収梁１６０よりなり、第１端梁部材１４０は、鉄道車両１０の一端に備えられ、第２端梁部材１５０は、鉄道車両１０の他端に備えられ、その前面がお互いに対向する位置に配設され、第１端梁部材１４０には、アルミニウム合金製の中空の押出角材を２つ重ねて用い、第２端梁部材１５０と対面する側には凸部を有するズレ止メ面１４１が設けられる。【選択図】図４
