The invention discloses a buffer joint for a traction rod of a maglev train and a traction rod device comprising the same. The buffer joint comprises a mounting seat, guide rods, an elastic buffer body I and an elastic buffer body II, a plurality of through holes are formed in the mounting seat, one guide rod is arranged in each through hole, and the guide rods can move in the axial direction of the through holes; the two ends of the guide rods extend out of the through holes, and one ends of the guide rods are provided with a limiting piece and an elastic buffer body I between the limiting piece and the mounting seat; the other ends of the guide rods are used for being connected with the support of a traction rod, and the elastic buffer body II is used for being arranged between the mounting seat and the support of the traction rod. By adopting the buffer joint provided by the invention, no matter whether the traction rod device is pulled or pressed, the shock isolation of the traction rod device under sudden change load can be realized, the influence on the shock impact of the maglev train is avoided, the comfort performance of the whole vehicle is improved, and the traction roddevice can be protected from being damaged.
本发明公开了一种磁悬浮列车牵引拉杆用缓冲接头以及包含该缓冲接头的牵引拉杆装置,缓冲接头包括安装座、导向杆、弹性缓冲体I和弹性缓冲体II;安装座上设有若干通孔,每个通孔内设有一根导向杆,导向杆可沿通孔轴向移动;导向杆的两端伸出通孔,导向杆的一端设有限位件,在限位件和安装座之间的弹性缓冲体I;导向杆的另一端用于与牵引杆的支座连接,弹性缓冲体II用于设置在安装座和牵引杆的支座之间。采用本发明提供的缓冲接头,牵引杆装置不论是受拉或受压,均可实现对突变载荷下牵引杆装置的隔震,避免对磁浮车辆震动冲击的影响,提高整车舒适性能,还利于保护牵引杆装置不受损坏。
