The invention discloses an aircraft tractor with an automatic tire releasing and neutral gear shifting device. The aircraft tractor comprises a tractor body. By arranging a hook ejection mechanism, a neutral gear shifting wheel and a wheel holding hydraulic cylinder, in the normal state, the hook ejection mechanism and the neutral gear shifting wheel are in the folded state, tires of an aircraft are locked through the wheel holding hydraulic cylinder, and when a vehicle-mounted power source is powered off, the wheel holding hydraulic cylinder rotates to relieve locking of the tires; moreover, a hook is popped out through the hook ejection mechanism, and a firefighter can conveniently pull the tractor through the hook; meanwhile, one end of a tractor head is lifted upwards through the neutral gear conversion wheel, then the driving wheel, in the gear state, at the bottom of the tractor head is lifted, and more labor is saved when the firefighter pulls the tractor body through the hook; and when a vehicle-mounted power supply fails, the effect of simultaneous linkage is achieved by popping up the hook, releasing the tires and shifting the neutral gear.
本发明公开了一种具有自动释放轮胎和空挡转换装置的飞机牵引车,包括牵引车体;通过设置挂钩弹射机构、空挡转换轮和抱轮液压缸,在正常状态下,挂钩弹射机构和空挡转换轮处于收起状态,通过抱轮液压缸对飞机的轮胎进行抱死,当车载电源断电时,抱轮液压缸转动解除对轮胎的抱死,并且通过挂钩弹射机构将挂钩弹出,方便消防员通过挂钩拉动牵引车,同时空挡转换轮将车头的一端向上抬起,进而使车头底部处于挡位状态下的驱动轮抬起,进而使消防员通过挂钩拉动牵引车体时更加省力,并且当车载电源断电时,弹射挂钩和释放轮胎以及空挡转换达到了同时联动的效果。
