The invention provides a rodless aircraft tractor with four-wheel drive, which belongs to the technical field of aircraft tractors. The accurate control of walking and steering actions of the tractoris achieved by adopting four electrically-driven driving units capable of independently steering by 360 degrees or +/-180 degrees as a power system and a steering system of a vehicle, and the vehiclecan well meet the condition that the control precision requirement is high; meanwhile, it is ensured that a gap can be reserved in a tractor body between two rear wheels of the tractor, tires of an aircraft landing gear can conveniently enter the center of the tractor body, it is ensured that four driving wheels of the tractor are evenly stressed, the motor power of a single driving wheel is reduced, the motor heating is reduced, the service life of equipment is fully prolonged, and the safety when the tractor drags an aircraft is improved; the four driving units are not mechanically connectedwith one another, do not need other hydraulic devices for assistance, are directly mounted on a chassis of the tractor, and the tractor is simple in structure, convenient to mount, and low in maintenance cost, the occupied space of the driving unit is small, and the overall boundary dimension of the tractor can be conveniently reduced.
提供一种具有四轮驱动的无杆飞机牵引车,属于飞机牵引车技术领域,通过采用四个电驱动的可独立360°或者±180°转向的驱动单元为车辆的动力系统和转向系统,实现牵引车行走、转向动作的精确控制,使车辆能很好满足控制精度要求比较高的条件;同时,确保牵引车两个后轮中间的车体可以留有缺口,便于飞机起落架的轮胎进入车体中心位置,保证车辆四个驱动轮的受力均匀,降低单个驱动轮的电机功率,降低电机发热,充分延长设备寿命,提高了牵引车牵引飞机时的安全性;四个驱动单元相互之间无机械连接,也不需要其他液压装置进行辅助,直接安装在牵引车的底盘上,结构简单、安装方便、维保成本低,驱动单元占用空间小,便于缩小牵引车整体外形尺寸。
