The invention relates to the technical field of aircraft front wheel turning driving, and discloses an unmanned aerial vehicle front wheel turning electric driving device which is characterized in that a motor drives a ball screw to rotate, the ball screw drives a lead screw nut shifting fork to linearly move, and the lead screw nut shifting fork stirs a force transmission assembly to drive an output shaft to rotate; the steering system has the advantages of being high in reliability, high in efficiency, high in maintainability, high in response speed, simple in system and the like. And the ball screw and the screw nut shifting fork are matched for use, so that a self-locking function can be achieved, and the undercarriage is prevented from shimmy. In addition, a damping stator of the electromagnetic damper is fixedly installed on the shell, a damping rotor is connected with the output shaft through a planetary gear torque increasing mechanism, the electromagnetic damper is powered on when the aircraft takes off and lands, electromagnetic resistance is generated, relative movement of the undercarriage is hindered, shimmy of the undercarriage is further reduced or prevented, and the shimmy reduction function is achieved.

    本发明涉及飞机前轮转弯驱动技术领域,公开了一种无人机前轮转弯电驱动装置,通过电机驱动滚珠丝杆转动,滚珠丝杆驱动丝杆螺母拔叉直线运动,丝杆螺母拔叉拨动传力组件带动输出轴转动,从而带动起落架支柱旋转实现前轮转弯功能,具有高可靠性、高效率、可维护性强、响应速度快、系统简单等优点。且采用滚珠丝杆和丝杆螺母拔叉的配合使用,能起到自锁功能,防止起落架出现摆振。此外,所述电磁阻尼器的阻尼定子固定安装在壳体上,阻尼转子通过行星齿轮增矩机构与输出轴连接,在飞机起飞和降落时电磁阻尼器通电,产生电磁阻力,阻碍起落架相对运动,进一步减小或防止起落架出现摆振,实现减摆功能。
