The invention belongs to the design technology of aircraft landing gear folding and unfolding mechanisms, and particularly relates to a rocker arm type side folding and unfolding landing gear which comprises a supporting column, a rocker arm, a buffer, a folding and unfolding actuator cylinder, an upper supporting rod, a lower supporting rod, an unlocking actuator cylinder and a supporting rod locking mechanism. The supporting column comprises a first supporting arm and a second supporting arm, and the first supporting arm is hinged to the rack through a heading hinge shaft; the other end of the retractable actuating cylinder is hinged with the second support arm; the rocker arm is hinged to the airplane wheel shaft and comprises a first end hinged to the second supporting arm and a second end located at the heading rear end of the first end, and the buffer is hinged between the heading rear end of the first supporting arm and the second end; the upper supporting rod is hinged between the rack and the lower supporting rod, the lower supporting rod is hinged to the second supporting arm, and the supporting rod locking mechanism is connected between the lower supporting rod and the supporting column. The main wheel track of the airplane can be increased through the arrangement mode of the outwards-extending supporting columns.

    本申请属于飞机起落架收放机构设计技术,特别涉及一种摇臂式侧收起落架,包括:支柱、摇臂、缓冲器、收放作动筒、上撑杆、下撑杆、开锁作动筒、以及撑杆锁机构;支柱包括第一支臂与第二支臂,第一支臂通过航向的铰接轴铰接在机架上;收放作动筒一端铰接机架,另一端铰接第二支臂;摇臂铰接在机轮轴上,其包括与第二支臂铰接的第一端以及位于第一端航向后端的第二端,缓冲器铰接在第一支臂航向后端与所述第二端之间;上撑杆铰接在机架与下撑杆之间,下撑杆再铰接第二支臂,下撑杆与支柱之间连接撑杆锁机构,本申请摇臂式侧收起落架可以保证限定载荷下较小的起落架高度,减小着陆机体载荷;外伸式支柱布置形式可以增加飞机主轮距。
