The invention relates to a main landing gear of an airplane. The main landing gear comprises an upper supporting column, an inclined supporting rod, a frame, a buffer supporting column, a lower rocker arm, a brake airplane wheel, a retractable actuating cylinder, a stable buffer, a lower lock and an upper lock, wherein the upper supporting column is respectively connected with the inclined supporting rod, the frame and the retractable actuating cylinder through the connector; the frame is respectively connected with the upper support column, the buffer support column and the stable buffer; the stable buffers comprise the front stable buffer and the rear stable buffer, the front stable buffer and the rear stable buffer are connected with the front brake machine wheel and the rear brake machine wheel through the front buffer supporting column and the rear buffer supporting column respectively, and the two ends of the vehicle frame are provided with vehicle frame double-lug bases and other structures connected with the buffer supporting columns. The vehicle has the advantages that by arranging the vehicle frame, the coordination stability of loads between the front brake machine wheel and the rear brake machine wheel is balanced, and the anti-bumping capacity in the ground skating process is improved; in addition, the space of a main landing gear cabin of the aircraft can be saved in the overall structure arrangement, and the anti-bumping capacity in the ground taxiing process is high.

    本发明涉及飞机主起落架,包括:上支柱、斜撑杆、车架、缓冲支柱、下摇臂、刹车机轮、收放作动筒、稳定缓冲器、下位锁及上位锁;其中,上支柱通过连接头分别与斜撑杆、车架、收放作动筒连接;车架分别与上支柱、缓冲支柱、稳定缓冲器连接;稳定缓冲器包括前稳定缓冲器和后稳定缓冲器,前稳定缓冲器和后稳定缓冲器分别通过前缓冲支柱、后缓冲支柱连接前刹车机轮、后刹车机轮,车架两端设有与缓冲支柱连接的车架双耳座等结构;本发明的优越效果在于,通过设置车架起到平衡前刹车机轮、后刹车机轮之间载荷的协调稳定性,提高地面滑跑过程中抗颠簸能力;另外,本发明整体结构设置上能够实现节省飞机主起落架舱空间,对地面滑跑过程中抗颠簸能力强。
