The invention provides a lower structural frame of a suspension frame, the suspension frame and a maglev train. The lower structural frame comprises two longitudinal beams, a plurality of cross beams, a first transition sleeper beam and a linear motor induction plate. Dewar devices are arranged on the longitudinal beams. The cross beams are arranged between the two longitudinal beams and are sequentially arranged at intervals in the length direction of the longitudinal beams, and the two ends of the cross beams are flexibly connected to the longitudinal beams correspondingly. The first transition sleeper beam extends in the direction perpendicular to the two longitudinal beams, and the first transition sleeper beam is flexibly connected to the two longitudinal beams. And the linear motor induction plate is connected to each cross beam. According to the lower structure frame, the longitudinal beams and the cross beams are flexibly connected to form a flexible component, relative displacement can be generated between the longitudinal beams when the lower structure frame passes through curve road conditions, and the curve passing ability is better. By arranging the first transition sleeper beam and flexibly connecting the first transition sleeper beam with the two longitudinal beams, the connection between the lower framework and the upper framework of the suspension frame is reduced, the comfort is improved, the decoupling capacity is improved, and the overall structural reliability of the suspension frame is better.
本申请提供一种悬浮架的下部结构架、悬浮架及磁悬浮列车,下部结构架包括:两个纵梁、多个横梁、第一过渡枕梁和直线电机感应板。纵梁上设置杜瓦装置。横梁设置于两个纵梁之间,且横梁沿纵梁的长度方向依次间隔设置,横梁两端分别柔性连接于纵梁。第一过渡枕梁沿垂直两个纵梁的方向延伸,第一过渡枕梁分别柔性连接于两个纵梁。直线电机感应板连接于各横梁。本申请的下部结构架纵梁和横梁之间柔性连接,形成了柔性构件,在通过曲线路况时,纵梁之间能产生相对位移,曲线通过性更好。通过设置第一过渡枕梁,且将第一过渡枕梁和两个纵梁柔性连接,减少了悬浮架下构架和上构架的连接,提高了舒适性,提高了解耦能力,使得悬浮架整体结构可靠性更好。
