Description
technical field:
the present invention relates to a kind of aircraft tire driver.
background technology:
the landing speed of aircraft is generally at 200 ~ 300 kilometers/hour.Aircraft remains static due to tire when landing, therefore aircraft tire and ground when land with this speed produce severe friction, impact tire, axle, and violent friction not only decreases Using Life of Tyre, while also dangerous.
summary of the invention:
the object of the invention is to provide a kind of aircraft tire driver for above-mentioned Problems existing, the friction on aircraft tyre and ground can be avoided, extend Using Life of Tyre.
above-mentioned object is realized by following technical scheme:
aircraft tire driver, its composition comprises: main support, mounting and fixing support and electromagnetic mechanism and support thereof on described main support, described fixed mount is connected electromagnetic mechanism by sliding rack with connecting rod, described sliding rack is installed aircraft landing speed measuring device, described aircraft landing speed measuring device Negotiation speed frequency converter connects frequency converter, described frequency converter connects variable-frequency motor, described electromagnetic mechanism connects the active rubber tire with aircraft tyre close contact, and the motor shaft of described variable-frequency motor connects initiatively rubber tire.
the working process of this aircraft tire driver is as described below: be fixed on airline landing gear strut by main support and electromagnetic mechanism support, and during aircraft landing, alighting gear is opened rear electromagnetic mechanism action and driven initiatively rubber tire, makes active rubber tire with aircraft tyre close contact; The voltage that the air speed recorded is changed into the 0 ~ 10V corresponding with air speed by aircraft landing speed measuring device delivers to speed in frequency conv, and the voltage transitions of 0 ~ 10V is the voltage of the frequency converter frequency corresponding with controlling aircraft tyre linear velocity by this speed in frequency conv.The voltage driven variable-frequency motor that frequency converter is sent here according to speed in frequency conv rotates, and drives initiatively rubber tire to drive aircraft tyre to rotate by the motor shaft of variable-frequency motor; Transducer drive variable-frequency motor makes aircraft tyre linear velocity be consistent with air speed; Aircraft speed after landing moves auto-breaking lower than electromagnetic mechanism after setting value, and aircraft tyre actuating device resets.
beneficial effect:
1, the present invention before aircraft landing according to setting-out line speed, driving aircraft tyre to rotate makes the linear velocity of its aircraft tyre before aircraft landing identical or close with the speed of aircraft, such aircraft when landing aircraft tyre and ground without to rub or friction contacts, minimizing is impacted and avoided the friction on aircraft tyre and ground, extend Using Life of Tyre, the tyre explosion avoiding aircraft tyre to cause due to strong friction generation high temperature, reducing or avoid aircraft safety may.
the present invention as the power of aircraft in adrm movement, can also eliminate aircraft towing.
accompanying drawing illustrates:
accompanying drawing 1 is main TV structure schematic diagram of the present invention.
accompanying drawing 2 is left views of accompanying drawing 1.
accompanying drawing 3 is annexation schematic diagrams of fixed mount and sliding rack.
detailed description of the invention:
embodiment 1:
aircraft tire driver, its composition comprises: main support 13, mounting and fixing support 12 and electromagnetic mechanism 8 and support 10 thereof on described main support, described fixed mount is connected electromagnetic mechanism by sliding rack 6 with connecting rod 9, described sliding rack is installed aircraft landing speed measuring device 5, described aircraft landing speed measuring device Negotiation speed frequency converter 15 connects frequency converter 4, described frequency converter connects variable-frequency motor 3 by cable 14, described electromagnetic mechanism connects the active rubber tire 1 with aircraft tyre close contact, and the motor shaft 2 of described variable-frequency motor connects initiatively rubber tire.
aircraft landing speed measuring device can adopt radar speedometer or GPS velometer to complete.
working process:
as shown in figure 1 and 2, be fixed on airline landing gear strut 7 by main support 13 and electromagnetic mechanism support 10, during aircraft landing, alighting gear is opened rear electromagnetic mechanism 8 action and is driven initiatively rubber tire 1, makes active rubber tire with aircraft tyre 11 close contact.The voltage that the air speed recorded is changed into the 0 ~ 10V corresponding with air speed by aircraft landing speed measuring device 5 delivers to speed in frequency conv 15, and the voltage transitions of 0 ~ 10V is the voltage of frequency converter 4 frequency corresponding with controlling aircraft tyre linear velocity by this speed in frequency conv.The voltage driven variable-frequency motor 3 that frequency converter 4 is sent here according to speed in frequency conv rotates, and drives initiatively rubber tire 1 to drive aircraft tyre 11 to rotate by the motor shaft 2 of variable-frequency motor.Frequency converter 4 drives variable-frequency motor 3 that aircraft tyre 11 linear velocity is consistent with air speed.Tire and ground frictionless contact during aircraft landing, extend Using Life of Tyre and aircraft tyre produces the possibility that high temperature makes tyre explosion owing to rubbing.
aircraft speed after landing moves auto-breaking lower than electromagnetic mechanism after setting value, and aircraft tyre actuating device resets.
main Function of the present invention is severe friction when avoiding aircraft landing between aircraft tyre and ground, extends the service life of aircraft tyre, thus also can be called device for prolonging service lives of aircraft tires.
