The invention discloses a bogie frame, a bogie and a trailer vehicle, and relates to the technical field of bogies. The bogie frame comprises two side beams, a first cross beam, a second cross beam and an anti-side-rolling torsion bar. One ends of the first cross beam and the second cross beam are connected with one side beam, and the other ends are connected with the other side beam; the first cross beam is provided with a hollow cavity, and the hollow cavity penetrates through the two ends of the first cross beam in the axial direction of the first cross beam; the two axial ends of the first cross beam are each provided with a torsion bar installation base, the two length-direction ends of the anti-rolling torsion bar are connected to the two torsion bar installation bases respectively, and the anti-rolling torsion bar is located in the hollow cavity. According to the bogie frame, the internal space of the first cross beam is fully utilized, extra installation space does not need to be occupied, and the structural layout of the bogie frame is more compact and reasonable. Normal functions of the anti-side-rolling torsion bar can be guaranteed, and the anti-side-rolling torsion bar can be protected from being hit by stone of a circuit.

    本发明公开了一种转向架构架、转向架及拖车车辆,涉及转向架技术领域。转向架构架包括两个侧梁、第一横梁、第二横梁以及抗侧滚扭杆;第一横梁和第二横梁均一端连接其中一个侧梁,另一端连接另一个所述侧梁;第一横梁设置有中空腔室,中空腔室沿第一横梁的轴向贯穿第一横梁的两端;第一横梁的轴向的两端均设置有扭杆安装座,抗测滚扭杆的长度方向的两端分别连接于两个扭杆安装座,且抗测滚扭杆位于中空腔室内。本发明提供的转向架构架充分利用了第一横梁内部的空间,不需要额外占用安装空间,使转向架构架的结构布局更加紧凑、合理。还可以保证抗侧滚扭杆正常功能的同时,保护抗侧滚扭杆免受线路石块击打。
