Abstract
The utility model provides a four point type shock attenuation undercarriage devices to double arc type, need fix and take off and land together in fixed wing uavs both sides and unmanned aerial vehicle, and the undercarriage passes through welded connection including back arc arm and frontal arc arm, the arc end department of back arc arm and frontal arc arm, and the wheel is installed respectively to the end, back arc arm, frontal arc arm and wheel are the landing gear an of an organic whole, and the arc arm adopts aviation aluminium materials to make, the wheel adopts the rubber material, totally four. Be equipped with the spike connecting plate in the draw -in groove of the parallel both sides of organism, it adopts two to be connected the mounting hole and to fix with the undercarriage, totally two connection mounting holes and two screws.
Description
Technical field
The utility model relates to a kind of four-point damping landing gear to double-arc shape, is related specifically to fixed-wing unmanned plane lifting support construction applications.
Background technology
The purposes development of fixed-wing unmanned plane specialized equipment is more and more extensive, and the volume and weight of its carrying equipment is increasing, needs to carry out overall lifting to the overall performance of unmanned plane.Unmanned plane in touchdown moment or on the runway of injustice, high ski-running is run time, with ground, violent shock occurs, except rubber tire can play fraction buffer action, most of Impact energy will lean on alighting gear to absorb, and proposes new requirement to the design of alighting gear.
Current landing gear mostly adopts the structure design of front and back bikini, and fixed-wing unmanned plane alighting gear is mostly taken turns by column support type structure and rubber machine and formed, and the widespread use of fixed-wing unmanned plane makes the landing environmental requirement of the various complexity of alighting gear demand fulfillment; The design of the alighting gear of civilian unmanned plane is more partial to practicality, is obtained easily on materials'use, the high performance material of antidetonation, resistance to compression, bending strength cannot be obtained as military aircraft, therefore on the basis of existence conditions, need a kind of Novel main alighting gear rational in infrastructure of design badly, while utilizing high performance material as far as possible in civilian, the overall performance of unmanned plane is improved by designing new landing gear structure, increase the weight of UAV flight's equipment, and installing easy disassembly, fixed-wing unmanned plane landing gear simple to operate.
Summary of the invention
Two arcuate structure designs that the utility model adopts are to propose a kind of four-point damping alighting gear scheme to double-arc shape, solve the demand improving fixed-wing unmanned plane overall performance by improving landing gear.
For reaching this object, following solution is proposed:
A kind of four-point damping landing gear to double-arc shape, refer to be arranged in parallel in body both sides two pairs of spike connecting panels, each spike connecting panel is provided with the main connecting bore of two arc-shaped shock-absorbing alighting gears that adapts, spike is provided with the docking draw-in groove be connected with fuselage; Each arc-shaped shock-absorbing alighting gear end is provided with the mount pad for installing rubber wheel, and wheel has been installed on alighting gear in use, without the need to again installing;
Further, alighting gear adopts double-arc shape oppositely to weld design, double-arc shape design defines contrary counteracting power on moment decomposition direction, impulsive force to body when actv. slows down unmanned plane landing, camber structure supports compared to current single straight arm type, and actv. slow down aloft air resistance;
The four-point design of damping alighting gear makes unmanned plane dangerous without handstand, and four wheels add the friction force with ground, allow strongly to brake, and can reduce the ground run distance after landing;
Further, the design of double rubber wheel has good directional balance, safer during cross wind landing; During ground taxi, handle and turn comparatively flexibly, if actual speed when landing is greater than specified value, then when main-gear touchdown, the impact acting on main wheel makes the angle of attack sharply reduce, and thus can not produce " jump " phenomenon as tail wheel type landing gear; Wheel adopts quality of rubber materials, each two of left and right, totally four, reduces load, not only can resistance to compression, moistureproof, and actv. enhances the cushioning ability of alighting gear;
Further, landing gear is assembled by backarc arm, frontal arc arm and wheel, is the take-off and landing device of an one, only adopts four screws to fix, easy to operate, time saving and energy saving; Alighting gear employing aircraft aluminum, comprises two backarc arms and two frontal arc arms are lightweight, and intensity is large, can adapt to various severe ground and takes off and land;
Preferably, adopt Design of Screw Thread between all mount pads and mounting hole, nut connects.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is alighting gear lateral plan of the present utility model.
Fig. 2 is alighting gear birds-eye view of the present utility model.
1. spike connecting panels, 2. location and installation hole, 3. backarc arm, 4. body, 5. wheel, 6. frontal arc arm in figure.
Detailed description of the invention
Elaborate below in conjunction with accompanying drawing.
Alighting gear of the present utility model, as a kind of four-point damping landing gear to double-arc shape, needs to be fixed on the landing together with unmanned plane of fixed-wing unmanned plane both sides.
Fig. 1 and embodiment illustrated in fig. 2 in, the both sides that body (4) is parallel be provided with spike connecting panel (1), spike connecting panel (1) one end is provided with the draw-in groove be connected with body (4), and the other end is provided with mounting hole; The arc end place of backarc arm (3) and frontal arc arm (6) is by being welded to connect, end is separately installed with wheel (5), the landing gear be made up of backarc arm (3), frontal arc arm (6) and wheel (5) is arranged on spike connecting panel (1) by location and installation hole (2), adopts and be threaded between mount pad with mounting hole.
More than combine actual operation installation process, made relevant technical design and illustrated, these illustrate just in order to describe technical design of the present utility model and method of operation, and can not be interpreted as the restriction to protection domain of the present utility model in any form.Based on the explanation to this, those skilled in the art makes any amendment or equivalent variations according to technical spirit of the present utility model, all will drop in protection domain of the present utility model.
