The invention discloses a bogie frame and a railway vehicle, the bogie frame comprises two side beam mechanisms and a cross beam mechanism, the middle parts of the side beam mechanisms are connected with the cross beam mechanism, the end parts of the side beam mechanisms are used for connecting wheel set axle boxes, and the two side beam mechanisms are respectively connected with the two end parts of the cross beam mechanism; and a plurality of mounting positions for mounting different steering basic components are integrated on the cross beam mechanism. Compared with the prior art, the bogie frame disclosed by the invention does not need to be additionally provided with a plurality of mounting frames for mounting the steering basic components, but directly integrates the mounting positions on the cross beam mechanism, so that the bogie frame simplifies the side beam mechanism, is simple in structure, greatly reduces the weight of the bogie frame, realizes light-weight design, and is suitable for large-scale popularization and application. The fatigue life of the rail vehicle is prolonged, the running speed of the rail vehicle is further increased, and the bogie of the urban rail vehicle can be exchanged possibly through the beam mechanism integrated installation position.

    本发明公开了一种转向架构架及轨道车辆,其中转向架构架包括侧梁机构和横梁机构,侧梁机构的中部连接横梁机构,且侧梁机构的端部用于连接轮对轴箱,侧梁机构为两个,且分别与横梁机构的两端部相连,横梁机构上集成有多个用于安装不同转向基础部件的安装位。和现有技术相比,本发明所公开的转向架构架无需额外设置多个安装架安装转向基础部件,而是直接将安装位集成在横梁机构上,因此上述转向架构架简化了侧梁机构,结构简单,极大的降低了转向架构架的重量,实现了轻量化设计,提高了轨道车辆的疲劳寿命,进一步提升了轨道车辆行驶速度,而且通过横梁机构集成安装位使得城轨车辆转向架互换成为可能。
