The invention discloses an air bag suspension structure of a semitrailer. The structure comprises a suspension assembly and an air bag installed on the suspension assembly, and the suspension assembly comprises a top plate, a bottom plate, a starting mechanism and a standby shock absorption mechanism; the air bag is arranged between the top plate and the bottom plate; the starting mechanism comprises a limiting unit and an inserting plate fixed to the lower surface of the top plate; the standby shock absorption mechanism comprises a limiting ring and a standby spring which are arranged on the air bag in a sleeving mode, the lower end of the standby spring is fixed to the upper surface of the bottom plate, the upper end of the standby spring is fixed to the lower surface of the limiting ring, the limiting unit is connected with the limiting ring in a clamping mode, and the standby spring is in a compressed state; and when the air bag is compressed to the limit compression height of the air bag, the inserting plate enables the limiting ring to move upwards through the limiting unit and enables the limiting ring to make contact with the top plate. The invention solves the problem that a semitrailer loses the damping function when an air bag in the prior art cannot work normally, and can guarantee the running smoothness of the semitrailer.

    本申请公开了一种半挂车的空气气囊悬架结构,包括悬架组件、以及安装在悬架组件上的空气气囊,悬架组件包括顶板、底板、启动机构和备用吸震机构;空气气囊设置于顶板和底板之间;启动机构包括限位单元、以及固定于顶板下表面的插板;备用吸震机构包括均套装于空气气囊上的限位环和备用弹簧,备用弹簧的下端固定于底板的上表面,备用弹簧的上端固定于限位环的下表面,限位单元与限位环卡接连接,备用弹簧为压缩状态;空气气囊压缩至空气气囊的极限压缩高度时,插板通过限位单元使得限位环向上运动,并使限位环与顶板接触。本申请解决了现有技术中空气气囊不能正常工作时,导致半挂车失去减震功能的问题,本申请能够保证半挂车的行车平顺性。
