The bogie frame comprises two side beams arranged side by side and two cross beams arranged between the two side beams, the two ends of each cross beam are connected with the side beams through installation assemblies, and each installation assembly comprises an inner ring sleeve and an outer ring sleeve which is arranged on the periphery of the inner ring sleeve and fixedly connected with a longitudinal beam through a fastener. A rubber layer is arranged between the inner ring sleeve and the outer ring sleeve, and annular limiting pieces located on the inner sides of the side beams are arranged at the two ends of the cross beams; a boss extending to the position of the limiting piece in the axial direction of the outer ring sleeve is arranged at the end, facing the inner side of the side beam, of the outer ring sleeve, and a receding groove corresponding to the boss in position is formed in the limiting piece. Gaps are formed between the side wall of the receding groove and the boss and between the bottom wall of the receding groove and the boss. The transverse, vertical and longitudinal displacement of the elastic suspension is limited, and the maximum torsion angle between the cross beam and the side beam is limited.
本发明公开了一种转向架构架,包括并排设置的两个侧梁及设置在两个侧梁之间的两个横梁,横梁的两端均通过安装组件与侧梁连接,安装组件包括内圈套筒及设置在内圈套筒外周并通过紧固件与纵梁连接固定的外圈套筒,内圈套筒和外圈套筒之间设置有橡胶层,横梁的两端均设置有位于侧梁内侧的环形的限位件;外圈套筒朝向侧梁内侧的一端设置有沿外圈套筒的轴向方向延伸至限位件位置上的凸台,限位件上开有与凸台的位置相对应的让位槽;让位槽的侧壁与凸台之间、让位槽的底壁与凸台之间均具有间隙。本发明实现对弹性悬挂横向、垂向、纵向的位移进行限位,限制了横梁和侧梁之间的最大扭转角度。
