The invention provides a railway vehicle through passage lower portion supporting structure which comprises two symmetrically-arranged butt joint frame bodies (1) and a sealing structure, each butt joint frame body (1) is provided with a groove (1-2), a first butt joint end (1-4), a second butt joint end (1-5) and a second connecting end (1-9) which are sequentially arranged, and the grooves (1-2)are used for installing the sealing structure; the first butt joint end (1-4) and the second butt joint end (1-5) are arranged in an aligned mode, and a third connecting end (1-3) used for limiting the sealing structure is arranged between the first butt joint end (1-4) and the groove (1-2). The second connecting end (1-9) is of a 7-shaped structure and used for being connected with a cab apron (6). The two butt joint frame bodies which are symmetrically arranged are connected in a butt joint mode through the first butt joint end and the second butt joint end respectively, and the sealing structure is fixedly installed in the groove, so that the sealing performance of the through channel is effectively guaranteed.

    本发明提供了一种轨道车辆贯通道下部支撑结构,包括两个对称设置的对接框本体(1)和密封结构,所述对接框本体(1)上设有依次设置的凹槽(1‑2)、第一对接端(1‑4)、第二对接端(1‑5)和第二连接端(1‑9),所述凹槽(1‑2)用于安装密封结构;所述第一对接端(1‑4)与第二对接端(1‑5)对齐设置,且所述第一对接端(1‑4)与凹槽(1‑2)之间设有用于对密封结构进行限位的第三连接端(1‑3);所述第二连接端(1‑9)设置为7字形结构,用于与渡板(6)连接。本发明设计为对称设置的两件对接框本体分别通过第一对接端和第二对接端对接连接,并通过将密封结构固定安装于凹槽内,以有效保证贯通道的密封性。
