The invention discloses a linkage mechanism of an aircraft undercarriage cabin door follow-up switch, which comprises a cabin door linkage mechanism, and is characterized in that a first rocker arm and a second rocker arm are movably connected, the right end of the first rocker arm is movably connected with a rack, the first rocker arm is movably connected with the top of a hydraulic acting cylinder, and the lower end of a piston rod of the hydraulic acting cylinder is movably connected with the rack; a linkage disc is arranged outside a rotating shaft through a spline in a sleeving manner, the rotating shaft is mounted in a mounting circular ring, the left end of the second rocker arm is movably connected with the top of an undercarriage damping cylinder, a rolling pin groove allowing a rolling pin to penetrate through is formed in a driven disc, the bottom of a first connecting rod is movably connected with a second connecting rod, and the lower end of the second connecting rod is movably connected with a cabin door linkage shaft which is movably installed on a cabin door. When the undercarriage is completely folded, the undercarriage cabin door is just completely closed, automatic linkage closing of the cabin door is achieved when the undercarriage is folded, and the undercarriage cabin door is opened and closed in a linkage mode in the folding and unfolding process of the undercarriage.
本发明公开了一种飞机起落架舱门随动开关的联动机构,包括舱门联动机构,摇臂一和摇臂二之间活动连接,摇臂一的右端与机架的活动连接,摇臂一与液压作用筒的顶部活动连接,液压作用筒的活塞杆的下端与机架活动连接;联动盘通过花键套装在转轴的外部,转轴安装在安装圆环的内部,摇臂二的左端与起落架减震筒的顶部活动连接,从动盘上开设有供滚动销穿过的滚动销槽,连杆一底部活动连接有连杆二,连杆二的下端与舱门联动轴活动连接,舱门联动轴活动安装在舱门上;本发明使得起落架完全收起时,起落架舱门正好完全关闭,实现了起落架收起时舱门自动联动关闭,实现了起落架在收放过程中联动开关起落架舱门。
