The invention discloses a bidirectional driving four-wheel multifunctional hydraulic control method which comprises a hydraulic control method when a front cab controls running, a hydraulic control method when the front cab controls turning, a hydraulic control method when a rear cab controls running and a hydraulic control method when the rear cab controls turning. Switching of a plurality of oil ways is achieved through opening and closing of the valve set, so that the steering function of a front axle or a rear axle can be independently controlled by one cab, the problem that the steering function is single is solved, meanwhile, the position of a steering oil cylinder is automatically recognized through a position sensor, tire correction and centering are automatically conducted, in addition, the in-situ turning function is added, and the steering efficiency is improved. Through the hydraulic control method provided by the invention, the driving modes can be quickly switched, and the steering operation steps are simplified.

    本发明公开一种双向驾驶四轮多功能液压控制方法,包括前驾驶室控制行驶时的液压控制方法,前驾驶室控制转圈时的液压控制方法,后驾驶室控制行驶时的液压控制方法,后驾驶室控制转圈时的液压控制方法,通过阀门组的开闭实现多个油路的切换,从而实现一个驾驶室能单独控制前桥或后桥转向功能,解决转向功能单一的问题,同时,通过设置位置传感器实现自动识别转向油缸位置并自动进行轮胎校正对中,此外,还增加了原地转圈功能,通过本发明提供的液压控制方法,能够快速的对驾驶模式进行切换,简化转向操作步骤。
