The invention discloses a rolling type undercarriage with lateral displacement adjustment. The rolling type undercarriage comprises a buffer assembly (5), a rocker arm assembly (7), a T-shaped connector (2), a limiting connector (3), a sliding way (4), a guide rod (1) and an airplane wheel tire (6). An upper end lug of the buffer assembly (5) is hinged to an airplane body connector, and a lower end lug of the buffer assembly (5) is hinged to a double-lug lug in the middle of the rocker arm assembly (7). An airplane wheel tire (6) is mounted on a wheel shaft at the lower end part of the rocker arm assembly (7) through a bearing, a transverse shaft of the T-shaped joint (2) is clamped between double lugs at the upper end part of the rocker arm assembly (7), and a fixed included angle is formed between a longitudinal shaft of the T-shaped joint (2) and the rocker arm assembly (7); the two limiting connectors (3) penetrate into the rocker arm assembly (7) from the two sides of double lugs and are inserted into annular cavities in the two ends of a transverse shaft of the T-shaped connector (2), and the T-shaped connector (2) and the limiting connectors (3) are locked through screws. An up-and-down slide way (4) is arranged on the aircraft body structure, and the end cylindrical parts of the two limiting connectors (3) are arranged between the up-and-down slide way (4) and can laterally move and rotate in the slide way; a lug piece at one end of the guide rod (1) is hinged to a machine body, and a lug piece at the other end is hinged to double lugs at the lower end of the T-shaped connector (2). Lateral displacement of tires during landing can be effectively reduced, the landing stability of the rolling landing gear is improved, and meanwhile the impact load during landing is reduced.
本发明公开了一种带侧向位移调节的横摇式起落架,包括:缓冲器组件(5)、摇臂组件(7)、T型接头(2)、限位接头(3)、滑道(4)、导杆(1)及机轮轮胎(6);所述缓冲器组件(5)的上端耳片与飞机机身接头铰接,下端耳片与摇臂组件(7)的中部的双耳耳片铰接;所述摇臂组件(7)下端部的轮轴通过轴承安装机轮轮胎(6),上端部的双耳中间卡设有T型接头(2)的横轴,T型接头(2)的纵轴与摇臂组件(7)形成一个固定角度的夹角;两个限位接头(3)从摇臂组件(7)的双耳两侧穿入,插入T型接头(2)横轴两端的环腔内,T型接头(2)和限位接头(3)通过螺钉锁紧;飞机机身结构上设置有上下滑道(4),两个限位接头(3)的端部圆柱部分置于上下滑道(4)之间,可在滑道内实现侧向移动和转动;所述导杆(1)一端耳片与机体铰接,另一端耳片与T型接头(2)的下端的双耳铰接。可有效减小着陆时轮胎的侧向位移,提升横摇式起落架着陆稳定性,同时降低着陆时的冲击载荷。
