The invention belongs to the technical field of aircraft landing gears, and particularly relates to a landing gear rotating wheel mechanism which comprises a main supporting column, an auxiliary supporting column and an auxiliary supporting column. The main supporting column comprises an outer cylinder hinged to a rack and a piston rod arranged in the outer cylinder in a sleeved mode and connected with an aircraft wheel tire. The supporting rod comprises a lower supporting rod body hinged to the outer cylinder and an upper supporting rod body hinged to the lower supporting rod body, and the lower supporting rod body and the upper supporting rod body are folded and unfolded to achieve folding and unfolding of the undercarriage; the rotary clamp is rotatably sleeved on the outer cylinder, is connected with the supporting rod through a first connecting rod mechanism and is connected with the tail end of the piston rod through a second connecting rod mechanism; the first mechanism is used for converting the folding motion of the supporting rod into the rotating motion of the rotating hoop around the main outer cylinder, and the second mechanism is used for converting the rotating motion of the rotating hoop into the rotating motion of the piston rod; the upper pull rod, the lower pull rod and the rocker arm are utilized to form an undercarriage runner mechanism, and the purposes of rotating tires and reducing the storage space of the undercarriage are achieved by utilizing a folding and unfolding mechanism, a driving runner mechanism, a rotating piston rod and airplane wheel tires of the undercarriage.
本申请属于飞机起落架技术领域,特别涉及一种起落架转轮机构,包括:主支柱,包括与机架铰接的外筒以及套在外筒内与机轮轮胎连接的活塞杆;撑杆,包括与外筒铰接的下撑杆以及与下撑杆铰接的上撑杆,下撑杆与上撑杆折叠与展开实现起落架收放;旋转卡箍,可旋转套在外筒上,通过第一连杆机构与撑杆连接,通过第二连杆机构与活塞杆末端连接;第一机构,将撑杆的折叠运动转换为旋转卡箍绕主外筒的旋转运动,第二机构,将旋转卡箍的旋转运动转换为活塞杆的旋转运动;本发明利用上下两个拉杆以及一个摇臂,组成了起落架转轮机构,利用起落架自身的收放机构,驱动转轮机构,旋转活塞杆以及机轮轮胎,以达到旋转轮胎,减小起落架收藏空间的目的。
