The invention discloses a connecting device suitable for a light railway vehicle. The connecting device comprises a sleeve shell, a push-pull body capable of floating left and right is arranged in the sleeve shell, and a left buffer spring body and a right buffer spring body are installed between the left inner side wall and the right inner side wall of the sleeve shell and the push-pull body in an abutting mode, the connecting device comprises a short pull rod and a long pull rod which is connected to the push-pull body; and end part connectors, wherein the two end part connectors are respectively connected to the long pull rod and the short pull rod through a ball joint bearing. According to the connecting device, mechanical connection between two front and back adjacent vehicles is achieved through the end connectors, acting force generated when the front and back vehicles run is relieved through the push-pull body structural design capable of floating left and right, and the snakelike movement requirements of the front and back adjacent vehicles are met through the ball joint bearings in the end connectors, and vibration generated during operation is relieved. The connecting device is compact in structure, small in size and small in occupied installation space.
本发明公开了一种适于轻型铁路车辆的连接装置,包括套筒壳体,所述套筒壳体内具有一可左右浮动的推拉体,所述套筒壳体的左右两内侧壁分别与所述推拉体之间顶装有左、右缓冲弹簧体;以及短拉杆及连接于推拉体的长拉杆;以及端部连接头,两个端部连接头分别各通过一球头关节轴承连接于所述长拉杆、短拉杆。本申请的连接装置通过端部连接头实现前后相邻的两个车辆间的机械连接,通过可左右浮动的推拉体结构设计使得前后车辆运行时产生的作用力得到缓解,通过端部连接头内的球头关节轴承使得满足前后相邻车辆的蛇形运动需求,缓解运行时产生的震动。而且该连接装置结构紧凑体积小,占用安装空间小。
