Specific embodiment
The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As shown in Figure 1 to Figure 3, which includes two crossbeams 2 being laterally arranged, before 2 one end of crossbeam installation one
Wheel post 4 is equipped with a rotating bar 7 inside the preceding wheel post 4, is equipped with a fixed link 10, the outer wall set of the fixed link 10 in the middle part of the crossbeam 2
A fixing bolt 5 is connect, two crossbeams 2 are connected by a crossbeam fixed link 14, and a Rotational Cylindrical 9 is arranged in the bottom of the crossbeam 2, should
One connecting rod 13 is set inside Rotational Cylindrical 9, and the both ends of the connecting rod 13 are respectively mounted a hydraulic knock-off joint fixing head 15, the connecting rod
A hydraulic knock-off joint 11 is installed in 13 lower sections, a hydraulic stem 3 is arranged below the hydraulic knock-off joint 11, the bottom of the hydraulic stem 3 is equipped with
One hydraulic seat 12, the both ends of the hydraulic seat 12 are equipped with a hydraulic seat fixing head 8, wheel post after the other end of the crossbeam 2 is equipped with one
6, the inside of the rear wheel post 6 is equipped with a rotating bar 7, and the lower section of the crossbeam 2 is equipped with a pedestal 16.
The crossbeam 2 is connected by the fixing bolt 5 with the pedestal 16, to keep the crossbeam 2 solid with the pedestal 16
It is scheduled on together.
It is rotation connection between the preceding wheel post 4 and rear wheel post 6 and the crossbeam 2, to make the front wheels and rear wheels of aircraft
It can be rolled on runway.
It is movably connected between the hydraulic knock-off joint 11 and the hydraulic stem 3, thus will when making the front wheel landing of aircraft
The hydraulic stem 3 stretches, pressure-reducing cushioning when rear-wheel being facilitated to land.
The crossbeam 2 is higher than close to one end of front-wheel and reaches thick stick so that front-wheel be made to land prior to rear-wheel close to one end of rear-wheel
The effect of rod principle decompression.
