Present stage, common unmanned plane alighting gear was generally steel wire or carbon plate and/or aluminium sheet, was made by Laos's bending process, was fixed on the fuselage with rubber band or screw, although structure is simple, poor-performing causes the alighting gear distortion, sideslip, the situations such as fracture easily; Because alighting gear does not have good shock absorption device, in comparatively rough landing process, often cause the fuselage damage, alighting gear is difficult to the phenomenons such as reparation; The outward appearance of alighting gear is simple and crude coarse, affects the unmanned plane overall appearance.
This shows that above-mentioned existing unmanned plane alighting gear obviously still has inconvenience and defective, and demands urgently further being improved in structure, method and use.How to found a kind of new unmanned plane alighting gear, real one of the current important research and development problem that belongs to.
The utility model content
The technical problems to be solved in the utility model provides a kind of unmanned plane alighting gear, it is lightweight that it is had, good damping effect, be convenient to install, can be fit to by adjustment the unmanned plane of different take-off weights, and good looking appearance be generous, reasonable stress, have very high reliability, make unmanned plane deviation phenomenon can not occur, thereby overcome that existing unmanned plane alighting gear outward appearance is coarse and crude, poor-performing, easily cause the deficiency of fuselage damage.
For solving the problems of the technologies described above, a kind of unmanned plane alighting gear of the utility model, comprise along the symmetrically arranged wheel of fuselage axis, skid bar, digonal link, damper and the front rail and the rear transverse rod that are installed in fuselage bottom, wherein: the piston rod top of damper is connected with the rear transverse rod end, and damper bottom and wheel are rotatably connected; Skid masthead end and front rail are rotatably connected, and the bottom is connected with the bottom of damper; The digonal link top is connected with the rear transverse rod middle part, and the bottom is connected with the bottom of damper.
Further improve as the utility model, described digonal link, skid bar and air-pressure damping device are the thin wall alloy aluminum pipe.
Damping spring also is installed on the piston rod of described damper.
Described skid masthead end is rotatably connected by bulb bearing and front rail.
The bottom of described damper is equipped with oscillating bearing, and is connected with skid bar, digonal link by this oscillating bearing.
Described damper is hydraulic damper or air-pressure damping device.
Piston rod top and the rear transverse rod of described damper are rotatably connected, and described digonal link top and rear transverse rod are bolted.
The utility model compared with prior art has the following advantages:
1. this unmanned plane undercarriage cushioning is effective, lightweight, and good looking appearance is convenient to dismounting;
2. the alighting gear assembling and positioning is good, and unmanned plane landing direction is parallel with fuselage, the phenomenon of sideslip can not occur;
3. each parts of alighting gear are convenient to member replacing fully by machinework production;
4. alighting gear can adapt to by the model that changes the damper upper spring unmanned plane of Different Weight.
Description of drawings
