The invention relates to the technical field of rail transit, aims to solve the problem that a hinge structure with three rotational degrees of freedom cannot meet the requirement that a walking part passes through a horizontal curve for a uniformly-loaded and dispersedly-pulled embedded magnetic levitation walking part, and provides a suspension frame hinge structure which comprises a hinge seat I and a hinge seat II which are oppositely arranged, a shaft hole is formed in the first hinge seat, a pin shaft is installed in the shaft hole, the pin shaft penetrates through the shaft hole and can slide in the axial direction of the shaft hole, the first end of the pin shaft is connected with a spherical sliding bearing, and the spherical sliding bearing is installed on the second hinge seat; according to the hinged structure, three rotational degrees of freedom around the X axis, the Y axis and the Z axis and the translational degree of freedom in the X direction between the suspension frames are released, meanwhile, transmission of Y-direction force and Z-direction force between the suspension frames is guaranteed, and the evenly-borne and dispersed traction type embedded magnetic suspension running gear has good horizontal curve trafficability.
本发明涉及轨道交通技术领域,旨在解决对于均匀承载和分散牵引式的内嵌式磁浮走行部,具有三个转动自由度的铰接结构不能满足走行部通过平曲线的问题,提供一种悬浮架铰接结构,包括相对设置的铰接座一和铰接座二,所述铰接座一上开设有轴孔,所述轴孔内安装有销轴,所述销轴贯穿所述轴孔设置且能够沿所述轴孔轴向滑动,所述销轴的第一端连接有球面滑动轴承,所述球面滑动轴承安装在所述铰接座二上;本发明的铰接结构释放了悬浮架之间绕X、Y、Z轴的三个转动自由度和沿X向的平动自由度,同时保证了悬浮架间Y向力和Z向力的传递,使均匀承载和分散牵引式内嵌式磁浮走行部具有良好的平曲线通过性。
