Description
Technical field
This utility model relates to a kind of tail pulley structure, particularly relates to the unmanned plane tail pulley structure of a kind of pull-off pole band damping shock absorption.
Background technology
The takeoff and landing of fixed-wing unmanned plane uses sliding race form to complete mostly, existing unmanned plane tail wheel uses simple shock-absorbing reed, monolateral pull bar to drive mostly, bearing-free revolute pair structure, the stability of ground roll-out and accuracy cannot ensure, be easy to occur sideslip, speed to accumulate slowly, even landing time be hit damage, lose sliding race to slow down, keep the problems such as direction function, the big-and-middle-sized unmanned plane that most of fixed-wing unmanned plane, especially take-off weights are higher, its damage occurs mainly in the takeoff and landing stage.
Summary of the invention
Technical problem to be solved in the utility model is to provide the unmanned plane tail pulley structure of a kind of pull-off pole band damping shock absorption, its kinetic equation loss reduced during sliding race, shortens the landing distance of unmanned plane, improves unmanned plane and takes off the success rate of landing.Being suitable for the most accurate cunning the in different road surface to run, particularly when hogwallow starting heats, unmanned plane will not be gone off course, and error and diastema accomplish minimum, and easy to maintenance, durable.
This utility model solves above-mentioned technical problem by following technical proposals: the unmanned plane tail pulley structure of a kind of pull-off pole band damping shock absorption, it includes connecting fuselage, steering wheel, first rudder arm, second rudder arm, closure rudder, damping oil, damping spring, tail wheel, fixing axle, linking arm, main shaft, base, connect fuselage and steering wheel connects, first rudder arm two ends respectively be connected fuselage, closure rudder connects, second rudder arm two ends respectively with steering wheel, base connects, damping oil is positioned at above damping spring, linking arm two ends respectively with fixing axle, main shaft connects, main shaft and base connect, tail wheel is connected with fixing axle.
Preferably, described tail wheel uses the damping, buffering structure kneeling the damping of formula band.
Preferably, described base is double-deck stand alone type carbon fiber board embedded with metal bearing compound component.
Preferably, described main shaft uses concentric shafts band bearing seat structure.
Positive progressive effect of the present utility model is: this utility model reduces kinetic equation loss during sliding race, improves and sliding runs stability and accuracy, shortens the landing distance of unmanned plane, improves unmanned plane and takes off the success rate of landing.Being suitable for the most accurate cunning the in different road surface to run, particularly when hogwallow starting heats, unmanned plane will not be gone off course, and error and diastema accomplish minimum, and easy to maintenance, durable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the unmanned plane tail pulley structure of this utility model pull-off pole band damping shock absorption.
Detailed description of the invention
Provide this utility model preferred embodiment below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the unmanned plane tail pulley structure of this utility model pull-off pole band damping shock absorption includes connecting fuselage 1, steering wheel 2, first rudder arm 3, second rudder arm 4, closure rudder 5, damping oil 6, damping spring 7, tail wheel 8, fixing axle 9, linking arm 10, main shaft 11, base 12, connect fuselage 1 and steering wheel 2 connects, first rudder arm 3 two ends respectively be connected fuselage 1, closure rudder 5 connects, second rudder arm 4 two ends respectively with steering wheel 2, base 12 connects, damping oil 6 is positioned at above damping spring 7, linking arm 10 two ends respectively with fixing axle 9, main shaft 11 connects, main shaft 11 and base 12 connect, tail wheel 8 is connected with fixing axle 9.
This tail pulley structure belongs to the damping, buffering structure kneeling the damping of formula band, so can be with high-speed motion in the hollow location of ground injustice.Unmanned plane shock loading both horizontally and vertically can be passed to damping shock absorber by this utility model, impact energy is completely by absorber, ensure that tail pulley structure and control system are not hit, it is achieved when unmanned plane landing and hogwallow sliding race, direction is precisely controlled.Pull-off pole tail wheel steering control device, uses one to push away one and draws bi-directional drive, can effectively eliminate fit-up gap and diastema, improves sliding race stability and accuracy；Steering wheel is used for controlling pull-off pole steering wheel pull bar position, and such structure takes double-direction control tail wheel, is effectively guaranteed the direction accuracy of tail wheel, so that direction tail wheel can be with line sliding under high-speed motion.Tail wheel turns to and turns to employing the most independent relevant control method with rudder, tail wheel and turning to of rudder use same steering-engine, but use the most independent pull bar transmission moment of torsion, ensure that both is relevant, the control of rudder can be made again not because the problem of tail pulley structure is affected, it is ensured that the control accuracy of rudder.Pull bar is driven by rudder, for independent control direction rudder face, relevant but each independent to turning to of tail wheel, and the steerage of rudder and the course accuracy of rudder face have been effectively ensured.Tail wheel main shaft uses concentric shafts band bearing seat structure, base location to use double-deck stand alone type carbon fiber board embedded with metal bearing compound component.In the case of can keeping high speed vibration, main shaft is downward without diastema axis perpendicular, so that it is guaranteed that steering wheel will not deflect.
Particular embodiments described above; to of the present utility model solving the technical problem that, technical scheme and beneficial effect further described; it is it should be understood that; the foregoing is only specific embodiment of the utility model; it is not limited to this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, within should be included in protection domain of the present utility model.
