And during the grade lead screw that brakes is withdrawn, if any of the above-described lead screw reaches its displacement limits upward or downward, parking power at this time
It can satisfy the requirement of aircraft parking maximum, force.
If in addition, venting thrust in brake process, brake grade lead screw can be sprung back under the drive of brake disc.It is controlled during this
Device 500 processed needs to monitor 700 signal of parking stage pressure sensor, is more than certain limit to prevent brake grade lead screw rebound displacement, from
And parking grade lead screw is driven to generate excessive pressure to brake disc.
Further, in one embodiment of the utility model, in aircraft freedom of entry state, controller is according to brake
The pressure signal control bidirectional brake motor respective direction rotation of the parking of the pressure signal of vehicle, until pressure sensor is returned
Zero, brake grade lead screw and parking grade lead screw be not to wheel active force.
In a specific embodiment of the utility model, the principle of the utility model embodiment system 10 includes：
(1) controller 500 is instructed according to upper layer signal, and judgement is needed into braking state or parked state, and according to
History control data and brake grade, parking stage pressure sensor signal judge brake system status, and then complete corresponding
Control operation.
(2) during aircraft landing, wheel original state is free, therefore two-stage pressure sensor signal above-mentioned is
Zero.When upper layer signal instruction controller needs to enter braking state, controller controls brake motor and rotates forward, and drives brake grade silk
Thick stick accordingly completes brake, while parking grade lead screw is accordingly withdrawn.Meanwhile it being fed back according to brake stage pressure sensor 600, control
System reaches requirement brake pressure.
(3) when airplane motion state stops, and upper layer signal indicates that controller 500 needs to enter power-off parked state, then
Controller controls brake motor reversion, drives parking grade lead screw accordingly to complete parking movement, while grade lead screw that brakes is withdrawn.Together
When, it is fed back according to parking stage pressure sensor 700, after reaching requirement parking pressure, by system cut-off, at this time due to can be self-locking
Parking grade leadscrew-nut mechanism 400 is self-locking, and parking is completed.
(4) after electricity needs to move aboard, upper layer signal indicates that controller 500 enters tire free state, then controls
Device 500 control brake motor rotate forward so that above-mentioned two-stage lead screw reach simultaneously not with the standard clearance position of brake disc.
Specifically, as shown in figure 3, it mainly includes three levels that the utility model embodiment, which carries out aircraft brake control,：
(1) according to various types of signal, which kind of state controller judgement enters；
(2) under different conditions, controller control bidirectional brake motor is moved to respective direction；
(3) it is fed back according to signal, controls brake weight or parking power is met the requirements.
Further, under any operation circulation, control process initially enters the S101 link in Fig. 3.
Controller 500 acquires upper layer signal instruction, acquisition brake stage pressure sensor 600 and parking stage pressure sensor
700 signal, and history control data are integrated, so that judgement needs which kind of state of a control entered in which kind of S102.
By in S101 link, control process enters the S102 link in Fig. 3.
If controller 500 judges that aircraft is in descent in S101 link, then enter S102-1 link.At this point,
Since wheel original state is free, two-stage pressure sensor signal above-mentioned is zero.Controller 500 controls bidirectional brake electricity
Machine 100 rotates forward, and drives brake grade lead screw accordingly to complete brake, while parking grade lead screw is accordingly withdrawn.Enter S103- simultaneously
1 link, controller 500 are fed back according to the signal of brake stage pressure sensor 600 and parking stage pressure sensor 700, and control is stopped
Vehicle power reaches requirement brake pressure.In aforementioned brake process, if braking since airplane antiskid braking requires to need venting thrust
Grade lead screw can be sprung back under the drive of airplane wheel brake frictional disk 800.Controller 500 needs to monitor parking grade pressure during this
700 signal of force snesor is more than certain limit to prevent brake grade lead screw rebound displacement, to drive parking grade lead screw to frictional disk
Generate excessive pressure.
If controller 500 judges that airplane motion state stops, and upper layer signal indicates controller 500 in S101 link
When needing to enter power-off parked state, into S102-2 link.It is inverted at this point, controller 500 controls bidirectional brake motor 100,
Parking grade lead screw is driven accordingly to complete parking movement, while grade lead screw that brakes is withdrawn.Enter S103-2 link, controller simultaneously
500 feed back according to parking stage pressure sensor 700, after reaching requirement parking pressure, by system cut-off, at this time due to parking grade
Leadscrew-nut mechanism 400 is self-locking, and parking is completed.
If the judgement of controller 500 enters aircraft and powers on the state for needing to move, and upper layer signal indicates in S101 link
Controller 500 enters tire free state.Controller 500 controls bidirectional brake motor 100 and rotates forward at this time, and target is so that above-mentioned
Two-stage lead screw reaches the standard clearance position not contacted simultaneously with airplane wheel brake frictional disk 800.Enter S103-3 ring simultaneously
Section, controller 500 are fed back according to the signal of brake stage pressure sensor 600 and parking stage pressure sensor 700, control aforementioned two
Grade lead screw arrival requires position.
According to the utility model embodiment propose can self-locking parking double lead-screw Mechanical type airplane brake control system, lead to
Controller adjusting is crossed, brake motor is controlled when aircraft enters braking state and is rotated forward, controls and stops when aircraft enters parked state
Vehicle motor reversion, the control and regulation of brake and parking is carried out according to the different operating condition of aircraft, and parking grade lead screw can be self-locking, power-off
After parking task can be completed, it is at low cost to effectively improve the reliability of aircraft brake parking control, it is simple easily to realize.

5. it is according to claim 1 can self-locking parking double lead-screw Mechanical type airplane brake control system, which is characterized in that
The direction of motion of the brake grade lead screw and the parking grade lead screw is opposite always.
6. according to claim 1 or 5 can self-locking parking double lead-screw Mechanical type airplane brake control system, feature exists
In, the relative position between grade lead screw and the parking grade lead screw and wheel brake disc of braking meets preset condition,
In, the preset condition includes：
There are brake motor Shaft angles, so that the brake grade lead screw and the parking grade lead screw are not braked simultaneously with the wheel
Disk contact, and the distance between the brake grade lead screw and the wheel brake disc meet airplane antiskid braking for hardware system
Preset requirement；
Under any state, all there is no the brake grade lead screw and the parking grade lead screw and meanwhile with the wheel brake disc phase
The case where contact；
Under the brake operating condition, the brake grade lead screw above pushes away and when the parking grade lead screw is withdrawn, if any screw rod arrives
Up to its displacement limits upward or downward, then the brake weight meets aircraft brake maximum, force；
Under the parking operating condition, the parking grade lead screw above pushes away and when the brake grade lead screw is withdrawn, if any silk
Thick stick reaches its displacement limits upward or downward, then the parking power meets aircraft parking maximum, force.
