Example Embodiment

[0038]Example 1:

[0039]A shock-absorbing landing gear for aircraft, such asfigure 1 ,figure 2 ,image 3 ,Figure 5 As shown, it includes a support plate 1, a second base 6, a first damping mechanism, and a second damping mechanism. The second damping mechanism includes a first base 5 and a middle column 21. The top outer wall of the middle column 21 is welded On the bottom outer wall of the first base 5, the inner wall of the intermediate column 21 is rotatably connected with a positioning frame 22 through a rotating shaft. The bottom outer wall of the positioning frame 22 is fixed with a top plate 23 by bolts, and the bottom and outer walls of the top plate 23 are fixed with two bolts. Three brackets 24, the inner walls of the two third brackets 24 are both rotatably connected with a first folding plate 11 through a rotating shaft, and the inner walls of the two first folding plates 11 are both rotatably connected with a second folding plate 25 through a rotating shaft. The outer wall...

Abstract

The invention discloses an aircraft damping undercarriage and a mounting method thereof, and relates to the technical field of damping undercarriages. In order to relieve friction resistance borne bya rising and falling wheel when the rising and falling wheel makes contact with the horizontal plane, the undercarriage comprises a supporting plate, a second base, a first damping mechanism and a second damping mechanism, the second damping mechanism comprises a first base and a middle column, the outer wall of the top of the middle column is welded to the outer wall of the bottom of the first base, and the inner wall of the middle column is rotationally connected with a positioning frame through a rotating shaft; and a top plate is fixed to the outer wall of the bottom of the positioning frame through bolts, two third supports are fixed to the outer wall of the bottom of the top plate through bolts, and the inner walls of the two third supports are rotationally connected with first folding plates through rotating shafts. The mounting method of the undercarriage comprises the following steps that the supporting plate is fixed to an airplane through bolts. By arranging the third supports and a fourth support, the first folding plates and a second folding plate can rotate relatively when the rising and falling wheel is under pressure.

Description

technical field [0001] The invention relates to the technical field of shock-absorbing landing gear, in particular to an aircraft shock-absorbing landing gear and an installation method thereof. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or it is completely or intermittently operated autonomously by the on-board computer, and the fixed-wing UAV takes off. A run-up is required at times, and taxiing is required when landing. This type of UAV has a long battery life, high flight efficiency, and a large load. Therefore, during the landing process, the landing gear of the entire aircraft, especially the landing wheels, bears a large force from the horizontal plane. Therefore, it is necessary to design a kind of aircraft landing gear with shock-absorbing function to effectively damp the landing gear. [0003] After searching, the Chinese patent appl...
