Abstract
The invention belongs to Aeronautics and Astronautics and near space technical field, are related to a kind of integrated form pillar gas cylinder, which is made of rocking arm, gas cylinder sealing cover, pressure supply pipeline, washer, inflation valve, inflation valve sealing cover.Row is welded between gas cylinder sealing cover and rocking arm cavity into seal cavity, the punching press into seal cavity by inflation valve, by pressure supply pipeline to the component pressure supply that is stamped, inflation valve sealing cover compression washer plays the role of second sealing.The present invention makes full use of the cavity of corbeling, without individual gas cylinder bottle, under conditions of not influencing undercarriage leg posting function, realize the function of storage gas, effectively cost is saved, weight is alleviated, occupancy of the gas cylinder to aircraft space is reduced without influence on sweeping space during folding and unfolding.
Description
Technical field
The invention belongs to aviation fields, and in particular to a kind of integrated form undercarriage leg gas cylinder is suitable for organic upper pressurising
The Aeronautics and Astronautics device of air source or contingency gas sources demand.
Background technology
Currently, generally using the pneumatic supply mostly used on independent gas cylinder storage aircraft on aircraft, disadvantage is to need solely
Vertical gas cylinder bottle, construction weight is heavier, need to independently occupy space in cabin, as air source for components such as buffer, tires
Pressurising or undercarriage, hatch door etc. are emergent to put, but usually be pressurized member distance farther out, need longer connecting line and more
Adapter coupling, weight and cost are higher.
The main force support structure of pillar and outer barrel as undercarriage mitigates construction weight to improve bearing capacity, pillar and outer
Cylinder is usually designed to the tubular structure of cavity, and cavity is usually not effectively utilized.
Invention content：
Goal of the invention
The present invention proposes a kind of integrated form undercarriage leg gas cylinder, simple in structure, make full use of undercarriage leg structure
Cavity, be not necessarily to individual gas cylinder bottle, do not influence undercarriage leg posting function under conditions of, realize storage gas
Function has effectively saved cost, alleviates weight, is widely portable to organic upper pressurising air source or emergent deflation source demand
Aeronautics and Astronautics device.
Inventive technique solution
The present invention proposes a kind of integrated form undercarriage leg gas cylinder, including rocking arm 1, gas cylinder sealing cover 2, pressure supply pipeline 3, pad
Circle 4, inflation valve 5, inflation valve sealing cover 6 form, and have cavity 101, inflation tube nozzle 102 on rocking arm 1, gas cylinder sealing cover 2 with
Between rocking arm 1 welding make cavity 101 seal, between pressure supply pipeline 3 and gas cylinder sealing cover 2 by sealing is threadedly coupled, inflation valve 5 and
It is threadedly coupled between the internal thread of the ozzle 102 of rocking arm 1 by sealing, washer 4 is sleeved on the ozzle 102 of rocking arm 1, and inflation valve is close
Capping 6 is threadedly coupled between the external screw thread of the ozzle 102 of rocking arm 1 by sealing, is played by tightening 602 compression washer 4 of nut
The effect of second sealing, gas pour storage in cavity 101 by inflation valve 5.
A kind of integrated form undercarriage leg gas cylinder according to claim 1, it is characterized in that：The gas cylinder sealing cover
(2) there is fuse hole (201) on.
Further, there is fuse hole (601) on inflation valve sealing cover (6).
Further, rocking arm (1), inflation tube nozzle (102) is other to be provided with fuse hole (103), the fuse hole of rocking arm (1)
(103) insurance is played between the fuse hole of inflation valve sealing cover (6) (601) prevents inflation valve sealing cover (6) from loosening.
Further, pressure supply pipeline (3) is provided with insurance hole, there is fuse hole (201) and pressure supply on gas cylinder sealing cover (2)
Pipeline plays insurance on (3), prevents from loosening between pressure supply pipeline (3) and pressure supply ozzle (202).
Advantageous effects
The present invention proposes a kind of integrated form undercarriage leg gas cylinder, simple in structure, make full use of undercarriage leg structure
Cavity, be not necessarily to individual gas cylinder bottle, do not influence undercarriage leg posting function under conditions of, realize storage gas
Function has effectively saved cost, alleviates weight.
Gas cylinder is integrated in the cavity of undercarriage leg by the present invention, simple in structure, during folding and unfolding to sweeping space without
It influences, reduces occupancy of the gas cylinder to aircraft space.Simultaneously because this integrated form pillar gas cylinder and undercarriage remaining part distance
Closer to, applied on machine it is emergent to the pressurising of the components such as buffer, tire or undercarriage put when, be pressurized member distance closer to,
Length of pipe can be effectively reduced, to reduce pipeline at and weight.
Disclosed by the invention is widely suitable to organic upper pressurising air source or the Aeronautics and Astronautics devices of emergent deflation source demand.

Specific implementation mode
The present invention is described in detail below in conjunction with the accompanying drawings, refers to Fig. 1-Fig. 6；
A kind of integrated form undercarriage leg gas cylinder, including rocking arm 1, gas cylinder sealing cover 2, pressure supply pipeline 3, washer 4, inflation work
Door 5, inflation valve sealing cover 6 form, and being welded between gas cylinder sealing cover 2 and rocking arm 1 makes cavity 101 seal, pressure supply pipeline 3 and gas cylinder
It is threadedly coupled by sealing between sealing cover 2, is connected by sealing screw thread between the internal thread of the ozzle 102 of inflation valve 5 and rocking arm 1
It connects, washer 4 is sleeved on the ozzle 102 of rocking arm 1, by close between the external screw thread of the ozzle 102 of inflation valve sealing cover 6 and rocking arm 1
Envelope is threadedly coupled, and plays the role of second sealing by tightening 602 compression washer 4 of nut, gas is poured by inflation valve 5
