The invention discloses a buffer device for an aircraft draw bar, comprising: a base provided with a mounting space; the pair of buffer assemblies are oppositely arranged and mounted in the mounting space, and each buffer assembly is provided with two buffers which are oppositely arranged in the first direction; the traction component is provided with a first end and a second end which are deviated from each other in the second direction, the first end is clamped between the two buffers of one buffer assembly, the second end is clamped between the two buffers of the other buffer assembly, and the first direction is perpendicular to the second direction; and when the traction component is subjected to external force, the traction component can freely move in the first direction under the action of the buffer assembly. According to the hydraulic buffering device, the sudden change load generated during aircraft traction pushing or dragging operation can be hydraulically buffered, and the influence of the sudden change load on an aircraft nose landing gear, a traction rod and the like during aircraft traction starting is reduced.

    本申请公开了一种用于飞机牵引杆的缓冲装置,包括:底座,其开设有一安装空间;一对缓冲组件,其相对设置且被安装在所述安装空间内,每个缓冲组件在第一方向上设有两个相对设置的缓冲器;以及牵引部件,其在第二方向上具有彼此背离的第一端和第二端,所述第一端夹设在一个缓冲组件的两个缓冲器之间,所述第二端夹设在另一个缓冲组件的两个缓冲器之间,其中,所述第一方向垂直于所述第二方向;其中,当所述牵引部件受到外力时,所述牵引部件能够在所述缓冲组件的作用下在所述第一方向上自由运动。本申请可以对飞机牵引顶推或拖拽操作时产生的突变载荷进行液压缓冲作用,减少飞机牵引启动中突变载荷对于飞机前起落架、牵引杆等的影响。
