The invention discloses a superconducting maglev vehicle undercarriage structure, which comprises a first connecting rod, a second connecting rod, a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, the first end of the second connecting rod is hinged to the superconducting magnet; one end of the third connecting rod is hinged to the center shaft of the walking wheel, the other end of the third connecting rod is hinged to the second end of the second connecting rod, and the hinge point of the third connecting rod and the second connecting rod is a first hinge point; one end of the telescopic driving device is hinged to the first hinge point, and the other end of the telescopic driving device is hinged to the superconducting magnet. Compared with the prior art, according to the undercarriage structure of the superconducting magnetic levitation vehicle, the axial load borne by the telescopic driving device is small, the working stroke is reduced, the size is reduced, and the needed installation space is reduced. The undercarriage is arranged on the superconducting magnet, so that the influence of spring deflection in the primary suspension device on the stroke of the undercarriage is reduced, the undercarriage is more miniaturized, and the structure of the suspension frame is simplified.

    本发明公开了一种超导磁悬浮车辆起落架结构,包括:第一连杆,一端与超导磁体铰接,另一端与走行轮的中心轴铰接;第二连杆,第一端与超导磁体铰接;第三连杆,一端与走行轮的中心轴铰接,另一端与第二连杆的第二端铰接,且第三连杆与第二连杆的铰接点为第一铰接点;伸缩驱动装置,伸缩驱动装置的一端铰接于第一铰接点,另一端铰接于与超导磁体上。本发明提供的超导磁悬浮车辆起落架结构,相较于现有技术,伸缩驱动装置承受的轴向荷载较小,工作行程减小,尺寸减小,所需的安空间减小。起落架设置于超导磁体上,减小了一系悬挂装置中的弹簧挠度对起落架行程的影响,起落架更加小型化,简化了悬浮架的结构。
