Description
Technical field
The present invention relates to Aircraft Anti-skid Break Control field, specifically a kind of two remaining shock type brake instruction transducer.
Background technology
Along with electronic anti-breaking brake technique is in the widespread use of aviation field, the stability of this system will directly have influence on the landing safety each time of aircraft.Brake instruction transducer is as the first command reception transferring elements of electronic anti-skid braking system, for system control unit provides the voltage signal be directly proportional to pilot control pedal displacement, as can be seen here, can brake instruction transducer the work of safety and steady, has vital impact to the running status of electronic anti-skid braking system.
Traditional brake instruction transducer is generally differential type design, and redundancy design is not enough, and each junction all adopts common screw-nut to connect, in use very easily occur because of vibration cause loosen, the phenomenon of the failure such as clamping stagnation.Two remaining linear movement pick-up as brake instruction collection, the core component of interpreting, adopts a series of web members such as self-locking nut, stop washer, toothed washer to carry out fastening by this example, possesses security to a certain extent, vibration resistance and general adaptability.
Summary of the invention
For overcoming because environment for use vibration causes internal fault in prior art, remaining is single, affects the deficiency that brake instruction transducer normally works, and the present invention proposes a kind of two remaining shock type brake instruction transducer.
The present invention includes travel(l)ing rest, set nut, stroke nut, push rod, sleeve, piston, fixed support, housing end plug, stop washer, spring, housing, locating sleeve, linear movement pick-up, the first toothed washer, the second toothed washer, self-locking nut and oscillating bearing.One end of sleeve is connected with one end of housing, and between described sleeve and housing, have four single coil spring lock washer light types; Locating sleeve is fixed on the inner chamber of housing.Linear movement pick-up adopts two remaining linear movement pick-up, is installed in locating sleeve; Two pull bars of described linear movement pick-up are all connected by the pull bar mounting hole of the via hole on housing end plug with the piston end surface being positioned at sleeve, to limit the direction of motion of pull bar.Described two pull bars are all set with spring.Described push rod is positioned at the other end of described sleeve, and one end that this push rod is coordinated with described piston mounts cover end contact that is interior into sleeve and described piston through socket end.The other end and the travel(l)ing rest of described push rod are connected.Set nut and stroke nut is set with at described push rod and the travel(l)ing rest circumferential surface held that is connected, by described set nut, push rod and travel(l)ing rest are connected, by regulating the distance between described stroke nut and described sleeve end cap, realize the control to pull bar total kilometres.Housing end plug is fixed on the other end of described housing.Support bracket fastened link loads in the center pit of described housing end plug.Described fixed support is set with toothed washer.Self-locking nut is set with in the outside of described toothed washer.
Described piston is the rectangular housing of xsect, and this piston two minor face places are arc-shaped edges.Have end cap in one end of this piston, there is the groove of arc-shaped at the geometric center place of this end cap, and this groove coordinates with the end face of described push rod working end.The via hole of pull bar is had respectively at this end cap two minor face places.The fixed orifice of four stop washers is evenly equipped with between described arc-shaped groove and described pull bar via hole.
The circumferential surface of described support bracket fastened connecting link has the groove coordinated with the boss on the second toothed washer inner ring; The length direction of described groove and the centerline parallel of connecting link.
The boss of one end of described housing end plug has the groove coordinated with the boss on the first toothed washer.The length direction of this groove is consistent with the length direction of this end cap, and the central axis in this slot length direction is in the center line of fixed support mounting hole being positioned at this end cap geometric center, and crossing with the center line of described fixed support mounting hole.
In the present invention, the linear movement pick-up of two remaining is arranged on housing cavity, and the both sides of linear movement pick-up are provided with locating sleeve.The housing end plug fillister head screw in four head with insurance holes is arranged on housing right side, support bracket fastened right cylinder end is arranged on housing end plug by a pair toothed washer and set nut, the circular hole of fixed support opposite side is embedded with oscillating bearing, and the support on fixed support and aircraft is hinged.The input and output terminal of linear movement pick-up is drawn from the socket installation base of housing, and by the mode gang socket of crimping, socket screw is arranged on the boss of housing upper surface.The pull bar of linear movement pick-up is limited in sleeve by piston and moves, and on every root pull bar, cover has back-moving spring, and piston two hexagonal self-locking nuts and stop washer are fixed on piston.Piston end cap is arranged on the movable end face of sleeve, and push rod is arranged on piston end and covers.The travel(l)ing rest similar with fixing rack structure is arranged on push rod by straight pin and nut, and travel(l)ing rest is connected with the pedal mechanism of aircraft.
The piston of barrel bore is arranged on pull bar, and for the displacement signal of push rod is passed to linear movement pick-up, back-moving spring that pull bar is set with ensures that sensor push rod when not working or driver recalls brake instruction is the state of stretching out.Piston two pairs of hexagonal self-locking nuts and stop washer cooperation are arranged on pull bar, and in the hole that stop washer one end press-in piston is reserved, the other end is stuck on hexagonal self-locking nut and plays good locking effect.
Movable, fixed support respectively with airplane tread mechanism and pedal frame hinged, embedded oscillating bearing make sensor receive brake or get off the brakes instruction time, the flexible rotating that all can to realize with fixed support oscillating bearing be axle center.
When the present invention works, external power source is its power supply, as long as pilot control pedal mechanism, send brake instruction, be connected travel(l)ing rest the rotation of pedal to be converted to straight-line displacement to pass to push rod with pedal, push rod promotes piston and moves inward, and compresses coupled linear movement pick-up pull bar, and linear movement pick-up produces the output signal linear with displacement, output signal is directly passed to the socket of housing upper surface, completes once command and exports.When driver send get off the brakes instruction time, back-moving spring makes push rod and pull bar reset, and brake electric signal decays to original state thereupon.In order to meet remaining requirement, the present invention adopts the linear movement pick-up of double pull rod structure, improves the reliability of product.When vibration occurs external environment condition, a series of locking device is ensured that the relative position of each mechanism significant change can not occur.
Compared with common brake instruction transducer, the present invention has following characteristics: by changing the connection fastening means of travel(l)ing rest and push rod, piston and pull bar, fixed support and housing end plug, reach brake instruction transducer can normally work under vibration, and steadily can export the demand of the voltage signal be directly proportional to displacement.The present invention adopts two redundancy design, and when wherein a passage breaks down, another passage still can normal output voltage signal, thus ensures the superperformance of airplane brake system under extreme landing condition.
