The inflation connecting structure comprises an inner cylinder and a wheel fork, the wheel fork is connected with the inner cylinder through a connecting shaft and a fixing device, the fixing device is installed in the inner cylinder in a sliding mode, a buffering air cavity is formed by the head of the fixing device and an inner cavity of the inner cylinder, and an air inlet channel communicated with the buffering air cavity is formed in the connecting shaft. The axial blind hole is formed from the shaft cap end of the connecting shaft to the shaft rod end of the connecting shaft, the radial hole is formed in the middle of a rod body of the connecting shaft and is perpendicularly communicated with the axial blind hole, the vent hole is formed in the fixator and corresponds to the radial hole, and an inflation valve is arranged at the opening end of the axial blind hole. The wheel fork is simple in structure and ingenious in design, an inflation structure is designed while the wheel fork is connected with the outer cylinder, installation is convenient, holes do not need to be additionally formed in the outer cylinder or the inner cylinder, the fatigue life of the inner cylinder and the outer cylinder is guaranteed, the machining cost is reduced, the inflation valve is arranged at the lower end of the undercarriage, inspection and maintenance are convenient, and the maintenance cost is reduced.

    本发明公开了一种起落架缓冲器的充气连接结构,包括内筒和轮叉,轮叉通过连接轴及固定器与内筒连接,固定器滑动安装在内筒内,固定器的头部与内筒的内腔形成缓冲气腔,所述连接轴的内部设有与缓冲气腔连通的进气通道,所述进气通道包括自连接轴轴帽端向连接轴轴杆端开设的轴向盲孔、开设在连接轴杆身中部与轴向盲孔相互垂直贯通的径向孔以及开设在固定器上对应径向孔的通气孔,所述轴向盲孔的开口端设有充气活门。本发明结构简单,设计巧妙,在轮叉与外筒连接的同时设计了充气结构,且安装方便,无需在外筒或内筒上另外开孔,保证内筒及外筒的疲劳寿命,减少了加工成本,充气活门在起落架下端,便于检查维护,降低了维护成本。
