The invention discloses a bogie frame, a bogie and a bullet train, and relates to the technical field of bogies. The bogie frame comprises two side beams, a first cross beam and a second cross beam; 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; in the length direction of the side beam, the side beam comprises a middle section and end sections arranged at the two ends of the middle section, and the width of the end sections is larger than that of the middle section. The middle section is of a bent structure with an arc-shaped concave part; the first cross beam and the second cross beam are both of a hollow tubular structure. The bogie frame provided by the invention is more compact in structural layout; the width of the end sections of the side beams is larger than that of the middle sections, spring sleeves can be conveniently installed on the end sections, and the installation reliability of the spring sleeves is improved. In addition, the first cross beam and the second cross beam are both arranged to be of a hollow tubular structure, the weight of the bogie frame is reduced, and light weight of the bogie frame is achieved.

    本发明公开了一种转向架构架、转向架及动车车辆,涉及转向架技术领域。转向架构架包括两个侧梁、第一横梁及第二横梁;第一横梁和第二横梁均一端连接其中一个侧梁,另一端连接另一个侧梁;沿侧梁的长度方向,侧梁包括中间段以及设置于中间段两端的端部段,端部段的宽度大于中间段的宽度;且中间段为具有弧形凹部的折弯结构;第一横梁和第二横梁均为空心管状结构。本发明提供的转向架构架的结构布局更加紧凑;侧梁的端部段的宽度大于中间段的宽度,方便在端部段安装弹簧套筒,提高弹簧套筒安装的可靠性。此外,第一横梁和第二横梁均设置为空心管状结构,有利于减轻转向架构架的质量,实现转向架构架的轻量化。
