The invention relates to the field of axles, in particular to a bogie assembly for a railway vehicle and the railway vehicle, the bogie assembly comprises a guide frame assembly, the bottom of the guide frame assembly is rotatably connected with guide wheels and guide safety wheels, and the guide wheels and the guide safety wheels are arranged at intervals in the length direction of the railway vehicle; the periphery of each guide wheel is in rolling contact with the inner wall of the rail; and at least part of the structure of the guiding safety wheel is located below the inner edge of the rail. The distance between the rotation axis of the guiding safety wheel and the symmetry plane of the guide frame assembly is larger than the distance between the rotation axis of the guide wheel and the symmetry plane of the guide frame assembly. According to the bogie assembly for the railway vehicle, on the premise that the emergency protection function is guaranteed, the structural strength of the guiding safety wheels and the lightweight design of the railway vehicle are improved, and the good rollover prevention function is achieved.
本发明涉及轮轴领域,具体涉及一种轨道车辆用转向架总成及轨道车辆,转向架总成包括导向框总成,导向框总成的底部转动连接有导向轮和导向安全轮,导向轮和导向安全轮沿轨道车辆的长度方向间隔设置,导向轮的外周用于与轨道的内壁滚动接触;导向安全轮的至少部分结构位于轨道内缘的下方;导向安全轮的旋转轴线与导向框总成的对称面的距离大于导向轮的旋转轴线与导向框总成的对称面的距离。本发明提供的轨道车辆用转向架总成在保证应急防护功能的前提下,有利于提高导向安全轮的结构强度和轨道车辆的轻量化设计,具有较好的防侧翻功能。
