The invention relates to the technical field of railway vehicles, and provides a bogie frame, a bogie and a railway vehicle. The bogie frame comprises a bearing main body and two plate springs, the bearing main body is integrally cast and formed by adopting a high-strength casting material, the bearing main body comprises two C-shaped beams which are oppositely arranged and two wing-shaped beams which are oppositely arranged and arranged between the two C-shaped beams, the two wing-shaped beams are respectively provided with a mounting channel, and the two wing-shaped beams are arranged in the mounting channel. The two C-shaped beams and the two wing-shaped beams jointly define a center pin channel used for installing a center pin. The two plate springs are installed on the two installation channels respectively and extend in the longitudinal direction of the bearing body, and the two ends of each plate spring are provided with cushion blocks used for being connected with a wheel set shaft sleeve respectively. The bearing body can be rapidly formed, the high strength mass ratio can be achieved, and meanwhile the welding defect of the framework can be avoided. The bearing body is simple in structure, the weight of the plate spring is far smaller than that of a traditional side beam due to the structural form of the plate spring, and the lightweight effect of the framework is obvious.
本发明涉及轨道车辆技术领域,提供一种转向架构架、转向架及轨道车辆。转向架构架包括承载主体和两个板簧,承载主体采用高强度铸造材料一体铸造成型,承载主体包括两个相对设置的C形梁以及设于两个C形梁之间的两个相对设置的翼型梁,两个翼型梁分别构造有安装通道,其中,两个C形梁和两个翼型梁共同围合形成用于安装中心销的中心销通道。两个板簧分别安装于两个安装通道,板簧沿承载主体的纵向延伸,各板簧的两端分别设有用于连接轮对轴套的垫块。使承载主体能够快速成型,并能实现高的强度质量比,同时还能避免构架焊接缺陷的产生。承载主体的结构简单,板簧的结构形式也使板簧的重量远小于传统的侧梁的重量,使构架轻量化效果明显。
