The invention provides a limitable automatic steering undercarriage and a working method thereof. The automatic steering undercarriage comprises an undercarriage upper sleeve, an undercarriage lower sleeve, an undercarriage anti-torsion arm, an undercarriage middle shaft, undercarriage wheels, an undercarriage connecting bow and a rotary spring, the undercarriage upper sleeve comprises a sleeve nut, and the undercarriage middle shaft comprises a middle shaft lead screw. Linear motion can be converted into rotary motion through motion between the sleeve nut and the center shaft lead screw. The undercarriage is simple in mechanical structure and good in economical efficiency, the undercarriage can automatically steer without manual operation, a large amount of manpower and material resources are saved, and the overall aerodynamic efficiency of the aircraft is effectively improved.

    本发明提供了一种可限位的自动转向起落架及其工作方法,所述自动转向起落架,包括起落架上套筒、起落架下套筒、起落架防扭臂、起落架中轴、起落架轮、起落架连接弓、回转弹簧,所述起落架上套筒含有套筒螺母,起落架中轴含有中轴丝杠。本发明可以通过套筒螺母和中轴丝杠之间的运动,将直线运动转换为旋转运动。本发明机械结构简单,经济性好,不仅使起落架不需人工操作即可自动转向,节省了大量的人力物力,也有效提高飞行器整体的气动效率。
