Technical field
The present invention relates to a kind of undercarriages using clamp button of the spring, and the aircraft of clamp button of the spring is specifically utilized
Undercarriage belongs to air equipment field.
Background technique
Undercarriage is aircraft lower part for taking off landing or support aircraft and for ground (water when ground (water surface) slides
Face) mobile accessories apparatus.Undercarriage is a kind of unique component for supporting whole airplane, therefore it is aircraft inseparable scarce one
Partly；Without it, aircraft just cannot be in ground moving.After taking off, undercarriage can be withdrawn depending on flying quality.It rises
Falling rack device is the important component with load and maneuverability of aircraft, is responsible for extremely during aircraft security landing
Important mission.Undercarriage is support system necessary to taking off, land, sliding race, ground moving and park, and is aircraft
One of main component, what the superiority and inferiority of performance was directly related to aircraft is used in safety.Lever or trailing arm type undercarriage tool
There is the main accessory for the fuselage for being connected to aircraft and trailing arm that one is pivotally attached to main accessory.Undercarriage extension and retraction system one
As using hydraulic as normal folding and unfolding power source, using cold air, electric power as back-up power source.Machine before general nose-gear is taken in forward
Body, and the nose-gear of certain heavy transports is laterally packed up.Main landing gear folding and unfolding form is broadly divided into along span side
To folding and unfolding and two kinds of chordwise folding and unfolding.Stored position lock, which is used to undercarriage to be locked in, receives upper and extended position, to have prevented
It falls when frame awing puts down and hit automatically and packs up automatically.For extension and retraction system, generally there are position instruction and warning
System.When aircraft landing, have an oleo-pneumatic shock absorber generally to provide effective damping, but they generally by oil or
The influence of gas needs regularly to safeguard, it would therefore be desirable to a kind of equipment that can substitute oleo-pneumatic shock absorber.
Summary of the invention
In view of the above-mentioned deficiencies, the present invention provides a kind of undercarriages using clamp button of the spring.
The present invention is achieved by the following technical solutions: a kind of undercarriage using clamp button of the spring, is by rising and falling

The elongation of spring support rod.
The spring supporting bar I can stretch, and shortest length is shorter than the length of hydraulic stem III.
The rotation axis with rotation axis connecting rod is rotated with the contraction and elongation of hydraulic stem I and hydraulic stem II
, when hydraulic stem I and the contraction of hydraulic stem II, rotation axis I is rotated clockwise, when hydraulic stem I and the elongation of hydraulic stem II, rotation
Axis I rotates counterclockwise.
The equipment for having the beneficial effect that undercarriage and can replacing oleo-pneumatic shock absorber with mechanical spring of the invention, subtracts
The influence of few oil gas, increases its stability；The stretching speed that hydraulic stem is controlled using clamp button of the spring makes its contraction speed
Slowly, elongation speed is fast；Aircraft utilizes spring supporting bar, it is possible to reduce the resistance of undercarriage extension and retraction system makes in landing
Rate when must extend is fast, and stretching, extension is fast；Aircraft can reduce undercarriage extension and retraction system using spring supporting bar when rising
Resistance so that rate when shrinking is slow, stability is high；It can make undercarriage using the undercarriage of clamp button of the spring
It can bear bigger its stability of pressure increase；Undercarriage, as power source, increases aircraft takeoffs and landings using three hydraulic stems
The stability of the extension and retraction system of frame；In the process of movement, spring bracing travels on the road to jolt and pressure is continuous
During variation, has the effect of damping, stablize during traveling.

Specific embodiment
A kind of undercarriage using clamp button of the spring is by undercarriage fixed device 1, spring supporting bar I 2, undercarriage
It support rod 3, hydraulic stem I 4, undercarriage telecontrol equipment 5, hydraulic stem II 6 and is formed with rotation axis connecting rod 7, it is described rise
It falls and is made of undercarriage fixed plate 101, hydraulic stem III 102 and rotation axis I 103 on the fixed device 1 of frame, the undercarriage
Telecontrol equipment 5 be by chassis 501, lifting/lowering support wheel 502, rotation axis II 503, spring supporting bar II 504, spring supporting bar III 506 and
What connecting shaft 505 formed, it is characterised in that: spring supporting bar I 2 is mounted on the fixed device 1 of undercarriage, and hydraulic stem III 102 is pacified
On the fixed device 1 of undercarriage, 3 one end of gear support bar is fixed on the front end of hydraulic stem III 102, gear support bar 3
Midpoint is fixed on the upper end of spring supporting bar I 2, and the other end of gear support bar 3 is fixed in rotation axis I 103, rotation axis I
103 are fixed on the fixed device 1 of undercarriage, and the rotation axis with rotation axis connecting rod 7 is fixed on the another of gear support bar 3
On end, II 503 one end of rotation axis on undercarriage telecontrol equipment 5 is fixed on chassis 501, is turned on undercarriage telecontrol equipment 5
II 503 other end of moving axis is fixed on the spring supporting bar III 506 on undercarriage telecontrol equipment 5, II 6 one end of hydraulic stem with have
Rotation axis connecting rod 7 connects, and the other end is fixed on gear support bar 3, and I 4 one end of hydraulic stem is fixed on undercarriage sportswear
5 are set, the other end is fixed on gear support bar 3, and one end of connecting shaft 505 is fixed on the rotation axis 7 with rotation axis connecting rod
On, the other end of connecting shaft 505 is fixed on the spring supporting bar II 504 on undercarriage telecontrol equipment 5, and lifting/lowering support wheel 502 is fixed
On chassis 501, spring supporting bar II 504 is connect with chassis 501, and the end of spring supporting bar III 506 and connecting shaft 505 connects
It connects.
When the hydraulic stem I 4 is retracted to most quarter butt, hydraulic stem II 6 also will shrink to most quarter butt.
When the rotation axis I 103 shrinks the hydraulic stem III 102, spring supporting bar I 2 is shunk, hydraulic stem III
When 102 elongation, spring supporting bar I 2 extends.
The spring supporting bar I 2 can stretch, and shortest length is shorter than the length of hydraulic stem III 102.
The rotation axis with rotation axis connecting rod 7 with the contraction and elongation of hydraulic stem I 4 and hydraulic stem II 6 and

When not working, the hydraulic stem III 102 on the fixed device 1 of undercarriage is shunk the device, drives splinter bar I 2
It shrinks, hydraulic stem I 4 and hydraulic stem II 6 are shunk, and are retracted to undercarriage in cabin, spring supporting bar I 2 is compacted at this time
It with elastic potential energy, the more can shrink the more slow during contraction, so that extension and retraction system tends towards stability；The device at work,
Hydraulic stem III 102 on the fixed device 1 of undercarriage extends, and drives splinter bar I 2 to extend, hydraulic stem I 4 and hydraulic stem II 6 are stretched
Long, the elastic potential energy of spring supporting bar I 2 is released, and hydraulic stem III 102 is made rate stabilization and to play aircraft during elongation
It falls frame and stretches out out of cabin to come in the process of movement, since spring bracing II 504 is on undercarriage telecontrol equipment 5,
So in the process of movement, spring bracing II 504 during traveling and pressure are continually changing on the road to jolt,
Have the effect of damping, stablizes during traveling.
For the ordinary skill in the art, introduction according to the present invention, do not depart from the principle of the present invention with
In the case where spirit, changes, modifications that embodiment is carried out, replacement and variant still fall within protection scope of the present invention it
It is interior.
