The invention discloses a speed regulation control method for a double-flow transmission system of a wheeled tractor. According to the method, when the operation resistance of a tractor and road adhesion conditions are changed, the slip rate of a driving wheel of the tractor is graded, speed regulation control is divided into two different priorities, namely trafficability priority and productionefficiency priority, and slip rate control and vehicle speed control are executed respectively. When the speed of the tractor is controlled, the current operation resistance of the tractor is graded,the transmission mode of a double-flow transmission system is determined, and speed change adjustment is conducted according to the highest productivity speed change rule, so that the production efficiency of the tractor is kept to the greatest extent.
本发明公开了一种用于轮式拖拉机双流传动系统的调速控制方法,是在拖拉机作业阻力和路面附着条件发生变化时,通过对拖拉机驱动轮滑转率进行分级,将调速控制分为通过性优先和生产效率优先两个不同的优先级,并分别执行滑转率控制和车速控制。本发明能在进行车速控制时,通过对拖拉机当前作业阻力进行分级,确定双流传动系统的传动模式,并以最高生产率变速规律进行变速调节,从而最大限度保持拖拉机的生产效率。
