The invention relates to the technical field of aviation appliances, and provides a hydraulic self-adaptive wheel holding device of an aircraft tractor, which comprises a halfpace for climbing of aircraft wheels, and two vertically arranged side plates are fixed at one end of the halfpace; according to the device, the upper edge groove can be punched to the upper wheel table through inertia in the later braking period of an airplane, the airplane wheel is buffered and braked through the buffering slope, the airplane wheel falls into the wheel groove of the supporting plate, and the lower supporting airplane wheel is driven to be slowly lowered till the clamping component clamps the wheel face of the airplane wheel; compared with the prior art, the clamping part is used for clamping the airplane wheel from the side face, meanwhile, the clamping part provides radial jacking pressure, so that the stability of the airplane wheel is improved, and meanwhile, the clamping part is used for clamping the airplane wheel from the side face and providing radial jacking pressure. The problem that an airplane wheel shakes in the traction process in the prior art is solved.
本发明涉及航空用具技术领域,提出了飞机牵引车的液压自适应抱轮装置,包括用于机轮爬升的梯台,所述梯台的一端固定有两个竖向设置的侧板;本发明能够利用飞机制动后期的惯性冲上沿坡口冲上轮台,利用缓冲坡对机轮进行缓冲制动,使机轮落入托板的轮槽内,由驱使下托持机轮向下缓慢降低高度,直至夹持部件抱夹于机轮的轮面上,然后通过驱使下由摇转部件推动对机轮的轮毂进行顶压固定,同时由同步驱使下推动向上抬升至与机轮轮胎抵触,相对于现有技术来说,本发明由夹持部件对机轮从侧面进行夹持,同时由夹持部件提供径向顶压力,以提高对机轮的稳定性,解决了现有技术中机轮在牵引的过程中会出现晃动的问题。
