Technical field
The present invention relates to a kind of airplane wheel and help drop method.
Background technology
In aircraft landing, aero tyre contact can accelerate to aircraft by frictionally in very short time behind ground by static
Sinking speed (generally 250-350Km/h), this tire, wheel hub, bearing to wheel can cause great shock loading.
In the starting stage of tire motion, tire rigid connection tread surface and quick rotation, but velocity of rotation and the not up to ground connection speed of aircraft
Degree, thus tire rotate when also in sliding friction state.On the one hand, sliding friction produces substantial amounts of heat, causes tire table
Face is drastically worn or worn out, or even causes wheel tire blow-out, endangers flight safety；On the other hand, the main wheel of aircraft both sides
Strictly speaking can not possibly contact to earth simultaneously, the wheel first to contact to earth the center of gravity of airplane can form a deflection torque relatively, induce peace
Full accident.
The content of the invention
Based on this, the defects of it is an object of the invention to overcome prior art, there is provided a kind of airplane wheel and help drop method,
It can effectively reduce aircraft wheel in landing and contact to earth the force of sliding friction being subject to and deflection torque, so as to greatly lifting safety
Property.
Its technical scheme is as follows：
A kind of airplane wheel, including tire, outer wheel hub and kernel portion, tire are set on outer wheel hub, and kernel portion is arranged on
The intracavitary of outer wheel hub, the inner surface of outer wheel hub are provided with polylith permanent-magnet steel, and kernel portion includes multiple coil groups, braking resistor, control
Device and wheel shaft processed, outer edge area of multiple coil component cloth in kernel portion is corresponding with polylith permanent-magnet steel, controller with it is multiple
Coil group, braking resistor electrically connect respectively, and wheel shaft is located on the central axis in kernel portion, and outer wheel hub is set on wheel shaft.
Preferably, the kernel portion also includes stator core and fixed mount, and stator core is set on fixed mount, described more
Individual coil group is arranged on stator core, and the wheel shaft is arranged on the center of fixed mount.
Preferably, coding disk is additionally provided with the outer wheel hub, coding disk electrically connects with the controller.
Preferably, the outer wheel hub passes through bearing and the wheel axis connection.
Preferably, this wheel also includes brake disc device, and the brake disc device is connected with the outer wheel hub.
Preferably, this wheel also includes shoe, and the shoe is connected with the outer wheel hub.
A kind of aircraft helps drop method, comprises the following steps：
When aircraft landing, before the tire interface ground on outer wheel hub, the controller in kernel portion opens operation simultaneously
It is powered to multiple coil groups, multiple coil groups accelerate rotation with the polylith permanent-magnet steel effect driving outer wheel hub in outer wheel hub on wheel shaft
Turn so that tire its linear velocity when contacting ground has approached the speed of now aircraft；Linear speed on aircraft landing rear tyre
When degree is identical with the speed of aircraft, controller interrupts the energization to multiple coil groups, connects braking resistor；When aircraft reaches default
Low speed or during stopping, controller is out of service.
The advantages of below to preceding solution or principle illustrate：
Above-mentioned airplane wheel, when preparing landing after aircraft drop, the controller in kernel portion opens operation
And be powered to multiple coil groups, coil group produces electromagnetic force after powered up makes outer wheel hub of the inner surface equipped with permanent-magnet steel accelerate rotation
Turn, that is, drive tire to accelerate rotation, the linear velocity of its outer surface has reached the speed being close with aircraft when tire interface ground
Degree, now, the speed difference of outer surface of tire and aircraft will be very small, and the force of sliding friction between surface of tyre and ground will very
Ground is small, and the action time of the force of sliding friction also can be extremely short, therefore tire is starting to contact ground to aircraft reaching identical cunning
During this of scanning frequency degree, the shock loading being subject to can be smaller, and the deflection torque on the one hand formed to the center of gravity of airplane is little,
On the one hand the destructiveness of tire is also greatly reduced, so as to greatly reduce the incidence of security incident.When winged
When linear velocity on machine landing rear tyre is identical with the speed of aircraft, controller interrupts the energization to multiple coil groups, now outer
Wheel hub is rotated along with tire, and the effect to kernel portion is seemingly generator, and controller can then connect braking resistor, this
The electric energy that wheel changes into kinetic energy rapidly consumes, and also generates braking moment simultaneously in consumption process, can make wheel more
Slow down soon, when aircraft reaches default low speed or stopped, controller is out of service.
