The invention provides a positioning pulling plate, a primary connecting structure, a bogie and a railway vehicle, and belongs to the technical field of railway vehicles, the positioning pulling plate comprises a plate body, and the plate body is provided with a first connecting end and a second connecting end; the plate body extends to the second connecting end from the first connecting end in the first direction in the mode that the plate body is gradually folded in the second direction. The two faces of the plate body are each internally provided with an integrally-formed reinforcing part, and the reinforcing parts extend to the second connecting end from the first connecting end in the first direction in the mode that the reinforcing parts are gradually expanded outwards in the third direction. One end of the positioning pulling plate is constructed to be large in width, the other end of the positioning pulling plate is constructed to be small in width, so that connection of components at the two ends of the pulling plate is achieved, the whole pulling plate is roughly of a fin-shaped structure, occupied space is greatly reduced, and small installation space is achieved; the compression resistance stability of the positioning pulling plate can be improved, and the rigidity is large.

    本发明提供一种定位拉板、一系连接结构、转向架及轨道车辆,属于轨道车辆技术领域,包括板体,板体具有第一连接端和第二连接端;板体由第一连接端沿第一方向以在第二方向逐渐收拢的方式延伸至第二连接端;且板体的两面内分别具有一体成型的加强部,加强部由第一连接端沿第一方向以在第三方向逐渐向外展开的方式延伸至第二连接端;通过将定位拉板一端构造为宽幅较大,另一端构造为宽幅较小,由此实现拉板两端部件的连接,整体大致为“鱼鳍形”状结构,极大减小了空间的占用,实现了较小的安装空间,且在连接拉板上设有隆起的加强部,这能够提升定位拉板的抗压稳定性,刚度较大。
