Description
Technical field
The invention belongs to airplane design technical field, the elastic stopping method and elastic stopping of specifically a kind of airplane wheel
Plate.
Background technique
The driven wheel of aircraft is preceding wheel mostly, and aircraft after lift-off, take in landing gear compartment with undercarriage by wheel,
Wheel is under effect of inertia in landing gear compartment, and also in high speed rotation, this may cause a systems such as nose-gear vibration and noise
Column adverse effect, nose-gear vibration cause connection to loosen the other equipment for being mounted on noselanding gear well, influence its normal work
The adverse effects such as work, and noise then can cause pilot driver uncomfortable, this is that flight is not permitted.Aircraft generally makes at present
Front-wheel method for locking is to increase brake gear in preceding wheel, and brake device structure is complicated, and weight is big, and aircraft is needed to provide
Power realizes front-wheel stop, power can be it is hydraulic or electric, both power require to increase pipeline or circuit is dynamic to realize
Power transmitting, further increases the complexity and weight of equipment of system.
A kind of front-wheel method for locking, the nose-gear are proposed in nose-gear wheel rotation stop device (CN206327565U)
Wheel rotation stop device includes: magnetic field components, and magnetic field components are mounted in noselanding gear well or are mounted on nose-gear pillar, is used
In generation magnetic field；And conductor part, conductor part be mounted in nose-gear wheel hub or with nose-gear wheel hub
In conjunction with the magnetic line of force for the cutting magnetic field when at least part of nose-gear wheel rotates in magnetic field.The technical pattern
It is more complex, it is related to multiple electromagnetic components, maintenance is complicated.
Summary of the invention
The purpose of the present invention is to provide one kind, and structure is simple, without stop power input a kind of airplane wheel it is soft
Property method for locking and flexible stop device.
A kind of flexible method for locking of airplane wheel, which is characterized in that contain the following contents: 1) having a stop device,
The stop device is equipped with friction immobilisation face containing flexible locking strip, steering idler wheel and back-moving spring, flexible locking strip, and flexibility is stopped
One end of dynamic band is connected on the first support, and the other end of flexible locking strip connect around idler wheel is turned to back-moving spring one end,
The back-moving spring other end is connect with the second support, is turned to idler wheel and is fixed by third support；2) above-mentioned first support, second
Seat, third support are separately fixed at suitable position in landing gear compartment, and making stop device not influences the folding and unfolding of undercarriage, while working as machine
When in wheel income to landing gear compartment, motion-stopping surface and the wheel tire of flexible locking strip are affixed, and the motion-stopping surface of flexible locking strip is automatic
Apply immobilising friction forces to wheel tire, wheel is made to stop inertia rotation.
In order to reduce noise and the vibration during stop, the first support, the second support, third support pass through one respectively
Rubber damping piece is fixed on suitable position in undercarriage cabin.
The beneficial effects of the present application are as follows: by flexible friction band, the automatic wheel to inertial rotation applies immobilising friction
Power, structure of the invention is succinct, has stronger inclusiveness to tire size, does not need non-rotation stop process and provides power, can preferably be bonded
Wheel surface of tyre.
Attached drawing is described in further detail the application with reference to embodiments.
Detailed description of the invention
Fig. 1 is the flexible stop device structural representation of airplane wheel.
Fig. 2 is the flexible method for locking principle signal of airplane wheel.
Number explanation in figure: 1 back-moving spring, 2 turn to idler wheels, 3 flexible locking strips, 4 first supports, 5 second supports, 6 the
Three abutments, 7 friction immobilisation faces, 8 wheels.
Specific embodiment
Referring to attached drawing, the flexible method for locking of airplane wheel provided by the present application contains the following contents: 1) having a stop
Device, the stop device are equipped with friction immobilisation containing flexible locking strip 3, steering idler wheel 2 and back-moving spring 1, flexible locking strip 3
Face 7, one end of flexible locking strip 3 are connected to 4 on the first support, and the other end of flexible locking strip around steering idler wheel and tenses bullet
One end of spring 1 connects, and 1 other end of back-moving spring is connect with the second support 5, and it is fixed by third support 6 to turn to idler wheel 2；2) on
It states the first support 4, the second support 5, third support 6 and is separately fixed at suitable position in landing gear compartment, influence stop device not
The folding and unfolding of undercarriage, while when in the income to landing gear compartment of wheel 8, motion-stopping surface 7 and the 8 tire phase of wheel of flexible locking strip 3
The friction immobilisation face 7 of patch, flexible locking strip 3 applies immobilising friction forces to 8 tire of wheel automatically, and wheel 8 is made to stop inertia rotation.
In implementation, the flexible locking strip is equipped with multiple friction plates and constitutes friction immobilisation face 7, between adjacent friction plate
There is gap, friction immobilisation face is made to keep flexible and is bonded with the surface of tyre of wheel 8.
In order to reduce noise and the vibration during stop, in implementation, the first support, the second support, third support difference
