The invention discloses a main undercarriage and an aircraft, the main undercarriage comprises two wheel sets, a connecting shaft and two support plates; wherein each wheel set comprises at least onetire, the two ends of the connecting shaft are connected with the two wheel sets in a one-to-one correspondence mode, the supporting plate is provided with a first connecting end and a second connecting end which are opposite, the first connecting ends of the two supporting plates are fixedly connected with the connecting shaft, and the second connecting ends of the two supporting plates are usedfor being hinged to an aircraft body; wherein the cross sections, in the direction perpendicular to the plate faces of the supporting plates, of the supporting plates are gradually expanded from the first connecting end to the second connecting end, the two supporting plates are oppositely arranged, and the relative position distance between the two supporting plates is gradually increased from the second connecting end to the first connecting end. The two wheel sets are located on the sides, deviating from each other, of the two supporting plates correspondingly. According to the technical scheme, the strength and stability of the undercarriage are enhanced, the stability and safety of taking off and landing of an airplane are improved, and the weight of the undercarriage is reduced.

    本发明公开一种主起落架和飞行器,其中,主起落架包括两轮组、连接轴以及两支撑板;每一所述轮组包括至少一轮胎,所述连接轴的两端与所述两轮组一对一连接,所述支撑板具有相对的第一连接端和第二连接端,两所述支撑板的第一连接端与所述连接轴固定连接,两所述支撑板的第二连接端用于与机体铰接;其中,支撑板沿垂直于自身的板面方向的横截面自第一连接端至第二连接端渐扩,且两所述支撑板相对设置,两所述支撑板之间的相对位置距离自所述第二连接端至所述第一连接端递增,两所述轮组分别位于两所述支撑板相互背离的一侧。本发明技术方案不仅增强了起落架的强度和稳定性,提高了飞机起降的平稳性和安全性,而且减轻了起落架的重量。
