The invention discloses a steering radius control method of an articulated steering tractor, which comprises the following steps: when the articulated steering tractor works, the steering angle of a steering wheel is transmitted to a steering controller through an angle sensor, and the steering controller calculates an articulated steering angle and a front wheel steering angle under the minimum steering radius and transmits a signal to a corresponding steering actuator; the front wheel steering angle sensor and the bowing steering angle sensor feed back a real-time bowing steering angle signal and a real-time front wheel steering angle signal to the steering controller, the steering controller adjusts a bowing steering angle and a front wheel steering angle, then the signals are transmitted to the corresponding steering actuator, and the bowing steering angle and the front wheel steering angle are changed through correction. Therefore, the steering radius of the bowing steering tractor is the lowest. According to the method, a steering actuator comprises three electric cylinders, one electric cylinder is additionally arranged on a steering trapezoid, front wheel steering and bowing steering are combined, and the steering radius of the bowing steering tractor during steering can be reduced to the maximum extent.

    本发明公开一种折腰转向拖拉机的转向半径控制方法,在折腰转向拖拉机工作时,方向盘转角通过角度传感器传递给转向控制器,转向控制器计算出最小转弯半径下的折腰转向角和前轮转向角,并将信号传递给对应的转向执行器,前轮转向角传感器和折腰转向角传感器将实时折腰转向角信号和实时前轮转向角信号反馈给转向控制器,由转向控制器对折腰转向角和前轮转向角进行调节,再将信号传递给对应在转向执行器,通过修正改变折腰转向角和前轮转向角,从而使折腰转向拖拉机的转向半径达到最低。本方法的转向执行器包括三个电动缸,其中一个加装在转向梯形上,将前轮转向与折腰转向相结合,可最大限度降低折腰转向拖拉机转向时的转向半径。
