The invention relates to a railway vehicle bogie hinged framework which comprises a left side beam, a right side beam and a hinged cross beam device, the left side beam and the right side beam are longitudinally arranged, the hinged cross beam device is transversely arranged and comprises an outer sleeve and an inner sleeve, the inner sleeve extends into the outer sleeve, and the outer sleeve and the inner sleeve are connected through a left bearing and a right bearing. The left side beam and the right side beam are mutually and freely twisted through the left bearing and the right bearing. The bogie disclosed by the invention belongs to an H-shaped integral framework, the hinged framework can bear forces in three directions and torques in two directions by virtue of the hinged cross beam device, and only releases the degree of freedom of transverse rotation, so that the bogie is good in uniform load performance, high in stability, high in curve passing safety and high in line distortion adaptability; therefore, the operation speed of the bogie on various lines can be increased, the hinged beam device is connected through the exposed bolt fastener, the disassembly and assembly process is simple, and maintenance is convenient.

    本发明关于一种轨道车辆转向架铰接构架,包括纵向布置的左侧梁、右侧梁和横向布置的铰接横梁装置,铰接横梁装置包含外套筒和内套筒,内套筒伸入外套筒内,外套筒和内套筒之间通过左轴承和右轴承相连,左侧梁和右侧梁通过左轴承和右轴承实现相互自由扭转。本发明属于H型整体式构架,依靠铰接横梁装置能使铰接构架承受三个方向力和两个方向扭矩,只释放绕横向转动的自由度,使转向架均载性能好、稳定性高、通过曲线的安全性高、适应线路扭曲能力强,从而使转向架能在各种线路上提高运行速度,铰接横梁装置采用暴露在外的螺栓紧固件进行连接,拆装过程简单,便于检修。
