The invention relates to the technical field of railway vehicles, and provides a bogie frame, a bogie and a railway vehicle. The truck frame includes a load bearing body and two leaf springs. The bearing main body comprises two oppositely arranged C-shaped beams and two oppositely arranged wing-shaped beams arranged between the two C-shaped beams, the two wing-shaped beams are respectively provided with a mounting channel, the two C-shaped beams and the two wing-shaped beams are respectively and integrally cast and molded, and the two C-shaped beams and the two wing-shaped beams are integrally cast and molded. The two C-shaped beams and the two wing-shaped beams are suitable for being connected in a welded mode, and 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, the plate springs 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 pair shaft sleeve respectively. A high strength-to-mass ratio is achieved, the welding seam proportion is reduced to a low level, and the welding seam is made to be away from a high-stress area.
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。承载主体包括两个相对设置的C形梁以及设于两个所述C形梁之间的两个相对设置的翼型梁,两个所述翼型梁分别构造有安装通道,其中,两个所述C形梁和两个所述翼型梁分别一体铸造成型,并且两个所述C形梁和两个所述翼型梁之间适于焊接相连,两个所述C形梁和两个所述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所述安装通道,所述板簧沿所述承载主体的纵向延伸,各所述板簧的两端分别设有用于连接轮对轴套的垫块。实现高的强度质量比,将焊缝比例降低至比较低的水平,使焊缝远离高应力区。
