Description
Technical field
This utility model is related to aviation braking technology field, more particularly, to a kind of aircraft braking system.
Background technology
After aircraft landing, brake generally by three kinds of modes.First is spoiler it is simply that aircraft wing upper surface
One row's sideboard, can increase air drag after expansion and force aircraft.Second is to be braked by brake, this
Planting mode of braking is conventional mode, plays main braking action.3rd is to coordinate wheel braking by trhrust-reversal device, this
Shi Feiji still has remaining lift, the effect on driving birds is not good of wheel braking.After one aircraft landing, even if simultaneously by above-mentioned three kinds of modes
It is braked, braking distance is still very big, and therefore, the present invention proposes a kind of new mode of braking being different from prior art, enters
One step carrys out shortening braking distance during second-mission aircraft landing.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of aircraft braking system, and the wheel sliding is had
Effect braking.
The technological means that this utility model adopts are as follows：
A kind of aircraft braking system, including bracing frame, rotating shaft and wheel, described wheel includes wheel hub and tire, described machine
Wheel is arranged in rotating shaft and is located at the both sides of bracing frame, is equipped with permanent magnet, described wheel hub is near bracing frame inside described wheel hub
Side be provided with ceramic carbon fibre wearing layer；Described rotating shaft is provided with brake unit, described brake unit include mounting seat, located at
Electric magnet within described mounting seat and the ceramic carbon fibre brake disc located at described mounting seat center, described mounting seat is leaned on
The side of nearly bracing frame is connected with an electric pushrod, and described electric pushrod can be moved reciprocatingly along rotating shaft by Motor drive.
Further, described mounting seat is sheathed in described rotating shaft.
Further, described ceramic carbon fibre brake disc is ceramic carbon fibre circular disk body.
Further, pottery by circular disk body and on circular disk body rubbing surface for the described ceramic carbon fibre brake disc
Porcelain carbon fiber wearing layer is constituted.
Compared to existing technology, the beneficial effects of the utility model are：
Using a kind of aircraft braking system provided by the utility model, by ceramic carbon fibre brake disc be provided with pottery
The wheel hub friction of carbon fiber wearing layer produces resistance, reduces the velocity of rotation of wheel；After energising, electric magnet produces magnetic simultaneously
Power absorption is provided with the wheel hub of permanent magnet, and this absorption affinity not only suppresses wheel to rotate, and reduces the velocity of rotation of wheel, and further
Increase the frictional force between ceramic carbon fibre brake disc and the wheel hub being provided with ceramic carbon fibre wearing layer, play the mesh of effective brake
, solve the longer technical problem of braking distance after aircraft landing in prior art.
Brief description
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below will be to required in embodiment description
Accompanying drawing to be used be briefly described it should be apparent that, drawings in the following description be only preferred reality of the present utility model
Apply example, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1 is bracing frame, 2 is rotating shaft, 3 is wheel, 31 is wheel hub, 32 is tire, 4 is permanent magnet, 5 is ceramic carbon
Fibre abrasion layer, 6 be brake unit, 61 mounting seats, 62 electric magnet, 63 be ceramic carbon fibre brake disc, 7 be electric pushrod, 8 be
Motor.
Specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
As shown in figure 1, a kind of aircraft braking system, including bracing frame 1, rotating shaft 2 and wheel 3, described wheel 3 includes wheel hub
31 and tire 32, described wheel 3 is arranged in rotating shaft 2 and is located at the both sides of bracing frame 1, and wherein, in described wheel hub 31, side ring sets
There is permanent magnet 4, described wheel hub 31 is provided with ceramic carbon fibre wearing layer 5 near the side of bracing frame 1；Described rotating shaft 2 is provided with system
Dynamic device 6, described brake unit 6 includes mounting seat 61, the electric magnet 62 within located at described mounting seat 61 and located at described
The ceramic carbon fibre brake disc 63 at mounting seat 61 center, described mounting seat 61 is connected with one near the side of bracing frame 1 and electronic pushes away
Bar 7, described electric pushrod 7 is driven and can be moved reciprocatingly along rotating shaft 2 by motor 8.
Further, described mounting seat 61 is sheathed in described rotating shaft 2.In the present embodiment, described ceramic carbon fibre braking
Disk 63 can be ceramic carbon fibre circular disk body.In other embodiments, described ceramic carbon fibre brake disc 63 can be by annular circle
Disk body and the ceramic carbon fibre wearing layer on circular disk body rubbing surface are constituted.
The operation principle of this utility model aircraft braking system is：
When aircraft landing slide need braking when, start motor 8 and drive electric pushrod 7, electric pushrod 7 makes brake unit 6
Close to wheel 3, ceramic carbon fibre brake disc 63 is rubbed with the wheel hub 31 being provided with ceramic carbon fibre wearing layer 5 and produces resistance, fall
The velocity of rotation of low wheel 3；Electric magnet 62 is energized, electric magnet 62 absorption producing magnetic force is provided with the wheel hub of permanent magnet 4 simultaneously
31, absorption affinity not only suppresses wheel 3 to rotate, and reduces the velocity of rotation of wheel 3, and further increases ceramic carbon fibre braking
Frictional force between disk 63 and wheel hub 31, plays the purpose of effective brake.It is energized when stopping motor 8 runs and stops electric magnet 62
Afterwards, electric pushrod 7 resets, and electric magnet 62 magnetic disappears, and this aircraft braking system eliminates braking.The utility model discloses it is a kind of
Aircraft braking system passes through frictional resistance and absorption affinity composite braking, reduces the velocity of rotation of wheel, plays the mesh of effective brake
's.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement done etc., should be included in this utility model
Within the scope of protection.
