The invention relates to the field of rail train side apron boards, and provides a rail train bogie side apron board structure and a rail train. The rail train bogie side apron board structure is usedfor being arranged on the two opposite sides of a bogie cabin in the width direction of a train. The side apron board structure comprises a side apron board body, and the side apron board body comprises a transition connecting board, an outwards-protruding arc-shaped board in arc transition connection with the transition connecting board and an inwards-extending board which is in transition connection with the outwards-protruding arc-shaped board and extends in the outwards-protruding direction away from the outwards-protruding arc-shaped board. According to the invention, the side apron board body is provided with the outwards-protruding arc-shaped board arranged in the width direction of the train, so that the side apron board is transversely widened in the width direction of the train,and the side apron board is prevented from resisting a bogie; and besides, the transition connecting board, the outwards-protruding arc-shaped board and the inwards-extending board are all in arc transition connection, the streamline degree is increased, the flow guide effect can be enhanced, and the aerodynamic performance is improved.
本发明涉及轨道列车侧裙板领域,提供轨道列车转向架侧裙板结构及轨道列车。该轨道列车转向架侧裙板结构用于沿列车宽度方向设于转向架舱的相对两侧,包括侧裙板本体,所述侧裙板本体包括过渡连接板、与所述过渡连接板圆弧过渡连接的外凸弧面板以及与所述外凸弧面板过渡连接并朝向远离所述外凸弧面板的外凸方向延伸的内延板。本发明侧裙板本体通过沿列车宽度方向设置向外凸的外凸弧面板,从而在列车宽度方向对侧裙板横向加宽,避免侧裙板与转向架相抗;此外,过渡连接板、外凸弧面板与内延板均采用弧面过渡连接,增加流线化程度,有利于增强导流效果,提高空气动力学性能。
