The invention discloses an articulated framework for a railway vehicle bogie, which is an H-shaped integral framework and comprises two groups of longitudinally arranged side beams and a group of transversely arranged articulated cross beam devices, concave sections are arranged in the middles of the two groups of side beams, and a group of articulated cross beam devices are connected between theconcave sections; an inner sleeve of the hinged cross beam device extends into an outer sleeve, the outer sleeve and the inner sleeve are connected through two bearings with a certain span in the left-right direction, the inner sleeve and the outer sleeve can freely rotate through the two bearings, and in other words, the two side beams can freely rotate in a nodding mode. The articulated framework releases the degree of freedom of rotation of the two side beams around the transverse shaft, the torsional rigidity is zero, the uniform load capacity, the line adaptive capacity, the curve trafficability and the operation stability of the bogie can be improved, and the contradiction between the operation stability and the curve trafficability of a traditional bogie is fundamentally solved.

    本发明公开了一种用于轨道车辆转向架的铰接构架,所述铰接构架为H型整体构架,包括两组纵向布置的侧梁和一组横向布置的铰接横梁装置,两组所述侧梁中部有下凹段,所述下凹段之间连接有一组铰接横梁装置;所述铰接横梁装置的内套筒伸入外套筒内,所述外套筒和所述内套筒之间通过左右有一定跨距的两个轴承相连,内套筒和外套筒通过所述两轴承可实现自由旋转,即两侧梁可做自由地相互点头扭转;所述铰接构架释放了两侧梁绕横轴旋转的自由度,扭转刚度为零,能提高转向架的均载能力、线路适应能力、曲线通过性和运行稳定性,从根本上解决了传统转向架运行稳定性和曲线通过性之间的矛盾。
