The invention relates to the technical field of civil aircrafts. The invention discloses an auxiliary brake retractable landing gear based on safe landing of a civil aircraft. The auxiliary brake retractable landing gear comprises a vehicle body, wings are arranged on the two side walls of the vehicle body, a first hydraulic cylinder is arranged in the middle of the interior of the vehicle body, the two side walls of the right side of the top end of the first hydraulic cylinder are rotationally connected with retracting and releasing structures, each retracting and releasing structure comprises a first connecting rod, and the top end of each first connecting rod is rotationally connected with the top end of the corresponding first hydraulic cylinder. At the moment, a sliding block buffersthe force in the inclination direction of a tire by compressing a spring and stretching a second damping rod; by arranging first damping rods, force in the vertical direction borne by the aircraft during falling can be buffered, impact force in the inclined direction and the vertical direction can be well absorbed, and other parts of the aircraft are protected against damage of the impact force tothe maximum extent.
本发明涉及民用飞机技术领域,且公开了一种基于民用飞机安全降落的辅助刹车收放式起落架,包括机体,所述机体的两侧壁均设置有机翼,所述机体内部的中间位置设置有第一液压缸,所述所述第一液压缸顶端的右侧两侧壁均转动连接有收放结构,所述收放结构包括第一连杆,所述第一连杆的顶端与第一液压缸的顶端转动连接。该基于民用飞机安全降落的辅助刹车收放式起落架,此时滑块通过压缩弹簧和拉伸第二减震杆从而对轮胎倾斜方向的力进行缓冲,通过设置第一减震杆可以对飞机下落时受到的竖直方向的力进行缓冲,可以很好的吸收倾斜和竖直方向的冲击力,最大程度的保护飞机其它零件不受冲击力的损害。
