Abstract
A kind of new nose-gear wheel brake apparatus, including outer barrel, band ear snail cap, installation bolt, brake shoes, spring, piston, piston rod and bolt assembly, spring is loaded on outer barrel, piston is arranged on the inner wall of outer barrel outlet portion, piston rod one end is stretched into the other end in piston and is connected by bolt assembly with brake shoes, band ear snail cap sleeve is closed to be passed through on installation bolt fastening aircraft fuselage in outer barrel outlet portion, outer barrel.The structural member that the new nose-gear wheel brake apparatus produces frictional force is metalwork, and abrasion consume is very small, does not have to replace within the whole product life cycle, maintainability is good；Braking time is short, efficient；Simple in structure, reliability is high.
Description
Technical field
It the utility model is related to aircraft nose landing gear wheel braking technology field, and in particular to a kind of new nose-gear machine
Take turns brake apparatus.
Background technology
At present the overwhelming majority aircraft nose wheels all there is no brake gear, when it is this kind of take off liftoff after, it is no braking fill
Wheel rotates at a high speed before the effect of putting is lower, and high-speed rotating preceding wheel can cause aircraft to be shaken, and this shake can cause a variety of
Harmful effect, such as take it is uncomfortable, flying panel shake cause aircrew observe or operating difficulties, constantly have alternate load
Act on airframe structure etc..The device that tradition is braked after being packed up to front-wheel mainly hauls rubber parts using easy spring and is adjacent to
Tire mode.Which is more serious to rubber parts abrasion, and, it is necessary to upgrade in time and safeguard, the abrasive dust of generation is more, and efficiency is not
Enough height.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of raising braking efficiency, and it is not easy to wear, it is same with aircraft
In the longevity, reduce the new nose-gear wheel brake apparatus of maintenance workload.
A kind of new nose-gear wheel brake apparatus, including outer barrel, band ear snail cap, installation bolt, brake shoes, spring,
Piston, piston rod and bolt assembly, spring are loaded on outer barrel, and piston is arranged on the inner wall of outer barrel outlet portion, piston rod one
End is stretched into the other end in piston and is connected by bolt assembly with brake shoes, and band ear snail cap sleeve is closed to be passed through in outer barrel outlet portion, outer barrel
On installation bolt fastening aircraft fuselage.
By taking above-mentioned technological means, the utility model obtains advantageous effects and is：The new nose-gear wheel
The structural member that brake apparatus produces frictional force is metalwork, and abrasion consume is very small, is not had to more within the whole product life cycle
Change, maintainability is good；Braking time is short, efficient；Simple in structure, reliability is high.
Brief description of the drawings
Fig. 1：For the structure diagram of the utility model.
Fig. 2：For the cut-away view of the utility model.
In figure：1st, outer barrel；2nd, band ear snail cap；3rd, installation bolt；4th, brake shoes；5th, preceding wheel；6th, spring；7th, piston；

Embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining practical new
Type, is not intended to limit the scope of the utility model.
A kind of new nose-gear wheel brake apparatus, including outer barrel 1, band ear snail cap 2, installation bolt 3, brake shoes 4, bullet
Spring 6, piston 7, piston rod 8 and bolt assembly 9；Spring 6 is loaded on inside outer barrel 1, retractable；Piston 7, piston rod 8 are formed
Component under spring force or external force effect along outer barrel axis direction back and forth movement；2 one side of band ear snail cap is by outer barrel 1, piston
7th, piston rod 8, spring 6 are fixed together, and limit 8 maximum projecting position of piston rod, on the other hand will be whole by installation bolt 3
Brake apparatus is fixed on fuselage relevant position；Brake shoes 4 is connected on piston rod 8 by rotatable bolt assembly 9, Ke Yigen
According to preceding 5 position of wheel and rotational case adjustment certain angle, it is bonded to greatest extent with tire, improves braking effect.
The operation principle of the utility model is：Current wheel 5 can top pressure brake shoes 4,4 type face of brake shoes and tire after packing up
Outer surface fits closely, and the load of spring pressurized strut output is acted on tire, produces frictional force opposite to the direction of rotation, is compeled
Wheel is set to slow down and stop.On the one hand band ear snail cap 2 connects outer barrel 1 and piston rod 8, form spring actuating system, another
Whole brake apparatus is connected on housing construction by aspect, adjusts amount of spring compression by varying its setting height(from bottom), realization rubs
Power is wiped to adjust.Brake shoes 4 employs the arc profile with the outside diameter such as wheel, plus the rotation tune that itself can do certain angle
It is whole, contact area is increased, improves braking efficiency.Brake shoes 4 is hardware, not easy to wear.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody some variations that some of which part may be made the principle of the utility model, belong to the utility model
Protection domain within.
