The invention provides an unmanned aerial vehicle steering system and an unmanned aerial vehicle. The steering system of the unmanned aerial vehicle is installed on a nose landing gear. A pillar; the strut piston rod is connected below the strut and can rotate relative to the strut; wherein a rotating hoop is arranged on the strut piston rod; the unmanned aerial vehicle steering system comprises a steering engine fixed to a supporting column, and an output shaft of the steering engine is vertically arranged downwards; the first end of the mechanical rocker arm is connected to an output shaft of the steering engine; a support lug on the side surface of a cylinder barrel of the horizontally arranged shimmy damper is pivoted to a second end of the mechanical rocker arm, and a first end of a piston rod at the front end of a barrel body of the shimmy damper is connected to the rotating hoop; wherein the steering engine, the mechanical rocker arm and the shimmy damper are connected in series; the shimmy damper is a piston type shimmy damper, and a replaceable piston adjusting damper is arranged in the shimmy damper. In the invention, the steering engine, the mechanical rocker arm and the shimmy damper are connected in series, the connection mode is simple, the composition is reliable, the structural gap can be reduced, and the transmission efficiency is improved.
本发明提供了一种无人机转向系统、无人机。该无人机转向系统安装于前起落架上,前起落架包括;支柱;连接于支柱下方,并可相对于支柱转动的支柱活塞杆;其中,支柱活塞杆上设置有转动卡箍;无人机转向系统包括:固定于支柱上的转向舵机,其输出轴竖直向下设置;水平设置的机械摇臂,其第一端连接至转向舵机的输出轴;水平设置的减摆器,其缸筒侧面的支耳枢接至机械摇臂的第二端,其筒身前端的活塞杆第一端连接至转动卡箍;其中,转向舵机、机械摇臂、减摆器串行连接;减摆器为活塞式减摆器,其内部设置有可更换的活塞调节阻尼。本发明中,转向舵机、机械摇臂、减摆器串行连接,连接方式简单,组成可靠,能够减少结构间隙,提高传动效率。
