Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figures 1 to 7, this operation of landing gear, comprises mobile jib 9, pedestal 4, motor, rocking arm 6, connecting rod, master connecting-rod 7, mobile jib pull bar 8; Wherein, the main body of pedestal 4 is dull and stereotyped, and flat board is provided with two plates separated relatively; Motor is steering wheel 5, because the steering wheel 5 of undercarriage with common model plane drives, therefore can separately for steering wheel to buy motor in driving, and cost is low.
Be provided with wheel 2 in mobile jib 9 one end, steering wheel 5 is fixed on pedestal 4, and the position between the two ends of master connecting-rod 7 is hinged on pedestal 4 by axle, and mobile jib 9 other end is also hinged on pedestal 4; Rocking arm 6 one end is connected with the rotating shaft of steering wheel 5, and connecting rod one end and rocking arm 6 other end are hinged, and master connecting-rod 7 one end and the connecting rod other end are hinged, and master connecting-rod 7 other end and mobile jib pull bar 8 one end are hinged, and mobile jib pull bar 8 other end and mobile jib 9 are hinged.
Master connecting-rod 7 one end is less than the distance of master connecting-rod 7 other end to the pin joint between master connecting-rod 7 and pedestal 4 to the distance of the pin joint between master connecting-rod 7 and pedestal 4, and stock and the mobile jib pull bar of master connecting-rod are hinged, and quarter butt and the connecting rod of master connecting-rod are hinged.Master connecting-rod 7 one end shifts to install to the body of rod of the pin joint between master connecting-rod and pedestal and the master connecting-rod other end to the body of rod of the pin joint between master connecting-rod and pedestal.Pin joint between mobile jib and mobile jib pull bar to the distance of the pin joint between mobile jib and pedestal is less than the distance between pin joint between mobile jib and mobile jib pull bar to wheel.
Mobile jib 9 one end is provided with sleeve 10, is provided with damping spring in sleeve 10, and the pole of wheel 2 is inserted in sleeve 10 and is connected with damping spring; Model plane slide on the ground, take off, wheel is subject to when landing impulsive force passes to damping spring in sleeve by the pole of wheel 2, by the impulsive force of damping spring buffering from ground, improve the stability of work.
