The invention relates to an aircraft dragging device based on a digital hydraulic motor, which belongs to the technical field of aircraft dragging devices and comprises an aircraft wheel spindle and a controller. The two ends of the aircraft wheel main shaft are rotationally connected with a first aircraft wheel and a second aircraft wheel respectively; the first aircraft wheel is connected with a first digital hydraulic motor; the second aircraft wheel is connected with a second digital hydraulic motor; the first digital hydraulic motor is connected with a first hydraulic system, and the second digital hydraulic motor is connected with a second hydraulic system. The aircraft has the beneficial effects that the digital hydraulic motor is additionally arranged on the undercarriage of the aircraft, and the aircraft wheels are driven to rotate through the digital hydraulic motor, so that the aircraft is dragged to slide on the ground, the oil consumption of an aircraft engine before the aircraft takes off and after the aircraft lands can be saved, the service life of the engine is prolonged, and the passenger transport cost is reduced; differential turning of aircraft wheels can be achieved, the hydraulic system can use an airborne hydraulic source as power input, the weight and the size of an aircraft do not need to be excessively increased, and the safety and the reliability of the aircraft are greatly improved.

    本公开涉及一种基于数字液压马达的飞机拖动装置,属于飞机拖动装置技术领域,包括机轮主轴、控制器;机轮主轴的两端分别转动连接有第一机轮和第二机轮;第一机轮上连接有第一数字液压马达;第二机轮上连接有第二数字液压马达;第一数字液压马达连接有第一液压系统,第二数字液压马达连接有第二液压系统。本公开的有益效果是:在飞机的起落架上加装数字液压马达,通过数字液压马达带动机轮转动,从而拖动飞机在地面滑行,能够节省飞机起飞前和降落后飞机发动机的油耗,延长发动机运行寿命,降低客运成本;可实现机轮的差速转弯,液压系统可使用机载液压源作为动力输入,无需过多增加飞机重量和体积,大幅提高了飞机安全性和可靠性。
