The invention discloses a farming tractor with a four-wheel drive system and a steering control method of the farming tractor, and relates to the technical field of farming tools. The farming tractor comprises a front drive axle and a rear drive axle, and a power gear shifting gearbox is connected between drive axle input flanges of the front drive axle and the rear drive axle; the power shifting gearbox achieves power input through an engine. Drive axle housings of the front drive axle and the rear drive axle are connected with the wheel side assemblies at the two ends through steering knuckles, and steering drivers are installed on the drive axle housings of the front drive axle and the rear drive axle. The control method comprises a conventional steering control mode, a small turning radius steering control mode and an oblique walking steering control mode. Switching of different steering control modes is achieved by controlling the steering angle difference value of the wheel side assembly of the front drive axle and the steering angle difference value of the wheel side assembly of the rear drive axle. Different functions such as front wheel steering, rear wheel steering and four-wheel simultaneous steering can be achieved through the steering drivers of the front drive axle and the rear drive axle.

    本发明公开了一种具有四轮驱动系统的农耕拖拉机及其转向控制方法,涉及农耕用具技术领域,农耕拖拉机包括前驱动桥和后驱动桥,前驱动桥和后驱动桥的驱动桥输入法兰之间连接有动力换挡变速箱,动力换挡变速箱通过发动机实现动力输入;前驱动桥和后驱动桥的驱动桥壳和两端的轮边总成均通过转向节连接,前驱动桥和后驱动桥的驱动桥壳上均安装有转向驱动器。控制方法包括常规转向控制模式、小转弯半径转向控制模式和斜向行走转向控制模式;通过控制前驱动桥和后驱动桥的轮边总成的转向角度差值,实现对不同的转向控制模式的切换。本发明利用前驱动桥和后驱动桥的转向驱动器可以实现前轮转向、后轮转向和四轮同时转向等不同功能。
