The invention discloses a double-shaft train bogie framework and a train, the double-shaft train bogie framework comprises two framework side beams and two framework end beams which form a square shape, a placement table extending towards one side is arranged in the middle of each framework side beam, and an air spring mounting seat is arranged on each placement table; a traction rod seat is further arranged on the upper surface of the middle part of the framework side beam; guide wheel mounting seats for mounting guide wheels are arranged at the two ends of the framework side beams; brake mounting seats located on the upper surfaces of the framework side beams are further arranged at the two ends of the framework side beams; a motor mounting seat is arranged in the middle of the framework side beam; a plurality of primary guide cylinders used for installing primary springs are further arranged on the framework side beams. The functions of a guide frame and a suspension are integrated into a multifunctional double-shaft bogie frame, the weight of the bogie is reduced, the structural compactness is effectively improved, meanwhile, the number of welding seams on the frame is reduced, welding deformation and stress concentration of materials are reduced, and the quality and safety of railway vehicles are further improved.
本发明公开了一种双轴列车转向架构架及列车,包括形成口字形的两根构架侧梁和两根构架端梁,构架侧梁中部设置有向一侧延伸的安置台,安置台上设置有空气弹簧安装座;构架侧梁的中部上表面还设置有牵引杆座;构架侧梁的两端均设置有用于安装导向轮的导向轮安装座;构架侧梁的两端还设置有位于构架侧梁上表面的制动器安装座;在构架侧梁中部设置有电机安装座;构架侧梁上还设置有若干个用于安装一系弹簧的一系导筒。本发明通过将导向架与悬架功能的集合为一个多功能的双轴转向架构架,减轻转向架重量,有效提高结构紧凑程度,同时减少构架上的焊缝数量,减小材料的焊接变形及应力集中,进一步提高了轨道车辆质量及安全性。
