RAIL VEHICLE BODY STRUCTURE

PROBLEM TO BE SOLVED: To provide a rail vehicle body structure which reduces manufacturing cost attained by improved simple structure having high strength against tractional force.SOLUTION: Provided is a rail vehicle body structure which has a roof body structure constituting a top surface, side body structures constituting side surfaces, a frame constituting an under surface and gable body structures constituting end surfaces, and in which body bolsters connecting bogies are jointed to the under surface of the frame. In the rail vehicle body structure, the body bolsters have body bolster top plates constituting top surfaces, body bolster bottom plates constituting under surfaces and body bolster ribs connecting the body bolster top plates and the body bolster bottom plates. In either or both of a position near to a center or a position near to a longitudinal end of the body bolster of the rail vehicle body structure, a longitudinal end of the body bolster bottom plate of the rail vehicle body structure projects toward the opposite side of the body bolster than a longitudinal end of the body bolster top plate of the rail vehicle body structure, the longitudinal end of the body bolster top plate of the rail vehicle body structure is joined to the under surface of the frame, and a part of the longitudinal end of the body bolster bottom plate of the rail vehicle body structure is joined to the under surface of the frame through a vertical plate extending in directions of height and width of the rail vehicle body structure.SELECTED DRAWING: Figure 2 【課題】牽引力に対する強度を簡素な構造で確保することにより、製作コストを低減した軌条車両構体を提供する。【解決手段】上面を構成する屋根構体と側面を構成する側構体と下面を構成する台枠と端面を構成する妻構体とを有し、台枠の下面に台車を結合する枕梁が接合された軌条車両構体において、枕梁は上面を構成する枕梁上面板と下面を構成する枕梁下面板と枕梁上面板と枕梁下面板を結合する枕梁リブとを有し、枕梁の軌条車両構体の長手方向の端部寄り又は中央寄りのいずれか一方又は両方において、枕梁下面板の軌条車両構体の長手方向の端部は枕梁上面板の軌条車両構体の長手方向の端部より枕梁反対寄りに突出し、枕梁上面板の軌条車両構体の長手方向の端部は台枠の下面に接合され、枕梁下面板の軌条車両構体の長手方向の端部の一部は軌条車両構体の上下方向と幅方向とに延伸する垂直板を介して台枠の下面に接合されるようにした。【選択図】図２
