The invention relates to the technical field of undercarriages of aircrafts, in particular to an undercarriage control mechanism of a basic coach aircraft, which comprises a mounting plate, moving wheels and a hydraulic rod, a round hole is formed in the top of the mounting plate, the hydraulic rod is slidably connected to the inner wall of the round hole, and a sleeve block is fixedly mounted at one end of a piston rod of the hydraulic rod. A sleeve block is fixedly mounted on the bottom of the mounting plate, a penetrating hole is formed in the sleeve block, a rotating shaft is rotatably connected to the inner wall of the penetrating hole, the moving wheels are fixedly connected with the two ends of the rotating shaft, four base blocks are fixedly mounted at the bottom of the mounting plate, and the same base shaft is fixedly mounted between every two base blocks. A hydraulic rod is impacted to drive a fixing plate to impact a baffle, so that a spring is compressed, meanwhile, two first connecting plates which are rotationally connected rotate relatively during jolting, a torsional spring and the spring can assist in resetting of a moving wheel under the combined action, effective buffering of the moving wheel is achieved, and the mode is long in buffering distance and good in damping effect.
本发明涉及飞机起落架技术领域,具体是一种基础教练飞机的起落架控制机构,包括安装板、移动轮和液压杆,所述安装板的顶部开始有圆孔,所述液压杆滑动连接于圆孔的内壁,所述液压杆的活塞杆一端固定安装有套块,所述套块上设置有穿孔,所述穿孔的内壁转动连接有转轴,所述移动轮与转轴的两端固定连接,安装板的底部固定安装有四个基块,每两个所述基块之间固定安装有同一根基轴,本发明当落地的飞机在行进过程中发生颠簸时,液压杆受到冲击带动固定板撞击挡板,使得弹簧被压缩,同时两块转动连接的连接板一在颠簸时发生相对转动,扭簧和弹簧的共同作用下可以辅助移动轮复位,实现对移动轮的有效缓冲,该种方式的缓冲距离较长,减震效果好。
