The lower end connection of the lower end of one telescopic rod, the second telescopic rod.
When aircraft is in flight course, ventral brake apparatus is placed on inside the ventral of aircraft by telescopic rod, when winged
When machine needs to brake in descent, is issued and instructed to abdomen brake apparatus by the control device of aircraft control room, first stretches
Contracting bar and the second telescopic rod stretch out ventral simultaneously, third brake block and ground face contact are driven, to play the role of braking.
As a kind of deformation, the lower end of the first telescopic rod of the ventral brake apparatus, the lower end of the second telescopic rod are distinguished
Connect the first brake block and the second brake block, pilot can according to circumstances select only to control one of brake block brake or
Two brake block are controlled simultaneously to be braked.
The landing gear brakes device includes: lifting lever, and tire connecting rod, tire, tire key, tire keyway, first is flat
Row telescopic rod, the first braking connecting rod, fixture nut, the second parallel telescopic rod, the second braking connecting rod, the first brake key, the
One braking keyway, the second brake key, the second braking keyway, the first vertical telescopic rod, the second vertical telescopic rod.
The landing gear brakes device is mounted on undercarriage, and the lifting lever is connected with tire connecting rod, and tire passes through
Tire connecting rod is connected with lifting lever, and tire key is connected with tire, and is evenly distributed on the two sides of tire, is formed between tire key
Tire keyway.
The first parallel telescopic rod and the second parallel telescopic rod are connect by fixture nut with lifting lever, and symmetrical
In the two sides of lifting lever, the first parallel telescopic rod and the second parallel telescopic rod are connect with the control device of aircraft control room, and first
Connecting rod is braked by the telescopic rod connection parallel with first of the first vertical telescopic rod, the second braking connecting rod is stretched vertically by second
The telescopic rod connection parallel with second of contracting bar, the first braking connecting rod, second, which are braked, is respectively arranged with the first system on the inside of connecting rod
Dynamic key, the second brake key；The first braking keyway is formd between first brake key, forms the second braking between the second brake key
Keyway.
When needing to brake during the aircraft landing, by the control device of aircraft control room to the first parallel telescopic rod and
Second parallel telescopic rod issues braking instruction, and the first parallel telescopic rod and the second parallel telescopic rod will be along the two sides of lifting lever
Horizontal stretching, meanwhile, the first vertical telescopic rod, the second vertical telescopic rod can be stretched down along the two sides of lifting lever, when downward
When being stretched over aircraft wheel position, the first braking connecting rod, the second braking connecting rod with Telescopic control the first system respectively
Dynamic key, the first braking keyway, the second brake key, the second braking keyway, between block and the tire key to aero tyre, tire keyway
In, phase mutual friction between keyway and tire key is braked, to play the role of braking, after end of braking, first is parallel flexible
Bar and the second parallel telescopic rod, the first braking connecting rod and the second braking connecting rod are moved to opposite direction respectively, and first is parallel
Telescopic rod and the second parallel telescopic rod can be by fixture nuts along doing clockwise movement, and finally move to the upper of lifting lever
Lower two sides, complete entire braking process.
Advantageous effects of the invention are as follows: firstly, by the way that tire key is arranged as brake apparatus in the two sides of aircraft wheel
A part, tire eccentric wear can be caused serious to avoid the brake key in braking process and aero tyre direct friction, meanwhile,
It also contributes to preventing leading to aero tyre temperature because the high temperature that frictional force excessive when braking generates directly is contacted with aero tyre
Spending height makes tire high temperature explode；Secondly, the present invention not only may be used by the rear portion setting ventral brake apparatus after the ventral of aircraft
To play the role of auxiliary braking, contact area of the aircraft in braking process with ground can also be increased, increase substantially system
The stationarity of aircraft when dynamic, ensures safety arrestment.
