The invention relates to an improved nose landing gear of an airplane. The nose landing gear comprises a front airplane wheel assembly, a gear and rack turning mechanism, a buffer supporting column, a retractable actuating cylinder, an upper lock, an inclined supporting rod, a lower lock, an outer cylinder, a turning hoop, an upper anti-torsion arm, a lower anti-torsion arm, a piston rod, a hanging ring assembly, a plunger, an upper cam, a lower cam and a sealing device. The buffering supporting column is provided with connectors connected with the front airplane wheel assembly, the gear and rack turning mechanism, the retracting and releasing actuator cylinder, the inclined supporting rod, the lower lock and an airplane body. The inclined supporting rod is provided with lugs which are respectively connected with the buffer supporting column, the retractable actuating cylinder and the lower lock, and the inclined supporting rod is also provided with a joint which is connected with an airplane body and the like; the nose landing gear has the advantages that structural parts of the nose landing gear can be reduced, the structure is relatively compact, and the stability and bumping resistance of an aircraft in the take-off and landing process are improved; according to the improved nose landing gear of the airplane, the space of the cabin body is saved, and the anti-bumping capability in the ground skating process is improved.
本发明涉及一种改进的飞机前起落架,包括:前机轮组件、齿轮齿条转弯机构、缓冲支柱、收放作动筒、上位锁、斜撑杆、下位锁、外筒、转弯卡箍、上防扭臂、下防扭臂、活塞杆、吊环组件、柱塞、上凸轮、下凸轮、密封装置;缓冲支柱设有分别与前机轮组件、齿轮齿条转弯机构、收放作动筒、斜撑杆和下位锁及飞机机身连接的接头;斜撑杆设有分别与缓冲支柱、收放作动筒、下位锁连接的耳座,斜撑杆还设有与飞机机身连接的接头等;本发明的优越技术效果在于,本发明所述前起落架能够减少起落架结构件,结构相对紧凑,增加了起飞与降落过程中飞机的稳定性抗颠簸能力强;本发明所述改进的飞机前起落架实现节省其舱体空间,对提高地面滑跑过程中抗颠簸能力强。
