摘要： A bogie frame for railway vehicles includes a pair of left and right side beams disposed along a direction of rails; a cross beam that connects the side beams to each other, and a mounting bracket for mounting a functional part, the mounting bracket being joined to the cross beam. The cross beam has a rectangular cross section and includes a top plate section, a bottom plate section, and a pair of side plate sections. The top plate section has a cutout opening extending to one of the side plate sections. The mounting bracket is inserted in the cutout opening and the mounting bracket and the top plate section are butt welded together. This configuration enhances welding workability for welding mounting brackets for mounting functional parts such as a traction motor, a gearbox, and a brake, and allows a greater degree of design flexibility in mounting the functional parts.
摘要翻译： 用于铁路车辆的转向架框架包括沿轨道方向设置的一对左右侧梁; 将侧梁彼此连接的横梁，以及用于安装功能部件的安装支架，该安装支架与横梁相连接。 横梁具有矩形横截面，并且包括顶板部分，底板部分和一对侧板部分。 顶板部分具有延伸到侧板部分中的一个的切口。 安装支架插入切口，安装支架和顶板部分对接在一起。 该配置提高了用于焊接安装支架的焊接可操作性，用于安装诸如牵引电动机，变速箱和制动器的功能部件，并且在安装功能部件时允许更大程度的设计灵活性。
