The beneficial effects of the utility model：The utility model is related to a kind of navigation undercarriage, the bottoms of undercarriage
Equipped with the wheel with pneumatic tire, wheel and damper are connected to body equipped with dead-man's device, load pillar on wheel
On, and the bump stroke in landing and sliding is passed into body, and common load pillar is as damper outer barrel, aircraft and ground
When violent shock occurs for face, damper can absorb most impact energy, and wheel is mainly made of wheel hub and tire, mainly
Effect is to support the weight of aircraft on ground, reduces the resistance of aircraft floor movement, and such undercarriage has preferable structure
Stability, economy and safety.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
【Description of the drawings】
Fig. 1 is a kind of structure diagram for undercarriage of opening the navigation or air flight of the utility model；
In figure：Under 1- housings, 2- lock spring, 3- safety pins, 4- wheels, 5- connecting shafts, 6- contraction poles, 7- loads pillar,
8- fixes sleeves, 9- connecting pins, pressurized strut in 10- receipts.
【Specific embodiment】
Refering to Fig. 1, the utility model, including housing 1, lower lock spring 2, safety pin 3, wheel 4, connecting shaft 5, contraction pole 6,
Load pillar 7, fixes sleeve 8, connecting pin 9, pressurized strut 10 in receipts.The bottom of undercarriage is equipped with the wheel 4 with pneumatic tire,
Wheel 4 and damper are connected on body equipped with dead-man's device, load pillar 7 on wheel, commonly use 7 conduct of load pillar
Damper outer barrel, wheel 4 are mainly made of wheel hub and tire.Safety pin 3 is mounted on load pillar 7, meanwhile, safety pin 3 is again
With it is lower lock spring 2 be connected, in the receipts pressurized strut 10 by connecting pin 9 mounted on load pillar 7 top.
Utility model works process：
During the work time, when aircraft landing, pilot need to only press a kind of navigation undercarriage of the utility model
Control undercarriage open button, the undercarriage of script folding and unfolding in the housing will opens voluntarily, in opening procedure, load branch
Column rotated ninety degrees first are changed to vertical state by initial horizontality, in order to avoid open load pillar voluntarily rebounds,
Safety pin and lower lock spring opened with certain angle simultaneously are just needed, to achieve the purpose that support and locked load pillar, aircraft exist
