The undercarriage comprises a cross beam assembly and supporting legs arranged at the two ends of the cross beam assembly. Machine wheels are rotationally mounted on the supporting legs; the cross beam assembly comprises two cross beams made of composite materials, and the two ends of the two cross beams are fixedly connected with the supporting legs through connecting joints. And connecting parts connected with the machine body are symmetrically arranged on the cross beam. The undercarriage adopts the cross beams made of composite materials, the undercarriage can be lightened to a large extent, meanwhile, the design of the two cross beams is adopted, a force transmission path is more concise, the influence of the bending moment of the aircraft course on the undercarriage is reduced to a large extent, ground loads can be evenly transmitted to the fuselage frame through the cross beams, and the undercarriage is more compact in structure. Therefore, the undercarriage can bear higher landing impact force, and the undercarriage can bear higher landing impact force while light weight is achieved.

    本发明公开了一种起落架,包括横梁组件和设于横梁组件两端的支撑腿;所述支撑腿上转动安装有机轮;所述横梁组件包括两根由复合材料制成的横梁,两根横梁的两端均通过连接接头与支撑腿固定连接;所述横梁上对称设有与机身相连的连接部。本发明的起落架采用复合材料的横梁,能够较大程度上使得起落架轻量化,同时采用两根横梁的设计,使得传力路径更加简洁,较大程度上减小飞机航向的弯矩对起落架的影响,能将地面载荷均匀的通过横梁传递到机身框上,从而使得起落架能承受更高的着陆冲击力,做到了轻量化的同时保证其能够承受更大的着陆冲击力。
