The invention discloses a detachable aircraft landing gear suitable for parking on a rugged road surface, and relates to the technical field of aircraft landing gears. The fuselage stability problem is solved. The landing gear specifically comprises a fixing frame, a retracting and releasing frame and aircraft wheels, the inner walls of the two aircraft wheels are rotationally connected with an axle, the outer wall of the axle is sleeved with wheel carriers, the outer walls of the tops of the two wheel carriers are connected with the retracting and releasing frame through a multi-connecting-rod damping mechanism, the outer wall of the top of the retracting and releasing frame is connected with the fixing frame through a multi-connecting-rod retracting and releasing mechanism, and the multi-connecting-rod damping mechanism comprises two first connecting rod assemblies and a damping assembly. According to the invention, first cross connecting rods and second cross connecting rods are arranged; longitudinal vibration generated by the aircraft wheels is converted into transverse vibration through the reversing effect of the first cross connecting rods and the second cross connecting rods, and compared with traditional longitudinal vibration absorption, the device has the advantages that the bounce amplitude of the fuselage is greatly reduced in the vibration absorption process, sothat the state of the fuselage is stable, and safety is improved.

    本发明公开了一种适用于起伏路面停靠的可装卸式飞机起落架,涉及飞机起落架技术领域;为了解决机身稳定问题;具体包括固定架、收放架和机轮,两个所述机轮的内壁转动连接有轮轴,轮轴的外壁套接有轮架,两个轮架的顶部外壁通过多连杆减震机构连接于收放架,收放架顶部外壁通过多连杆收放机构连接于固定架,多连杆减震机构包括两组第一连杆组件和一组减震组件。本发明通过设置有第一交叉连杆及第二交叉连杆,机轮产生的震动通过第一交叉连杆及第二交叉连杆的换向作用,将纵向震动转换为横向震动,相比传统的纵向减震,本装置使得在震动吸收过程中,机身的弹跳幅度大大减小,从而使得其状态较为稳定,提高了安全性。
