Electro-hydraulic walking system of skid loader and control method
The invention discloses an electro-hydraulic walking system of a skid steer loader and a control method, and relates to the technical field of engineering machinery, and the control method comprises the following steps: acquiring action information of a handle; the displacement control valve is controlled to act according to the action information of the handle, and the control current output to the displacement control valve is controlled; the displacement of the walking main pump and oil outlet of the oil outlet are controlled through the displacement control valve so as to control the rotating speed and the rotating direction of the first motor and the second motor. According to the control method, the action of the displacement control valve and the control current are controlled in an electric control mode, and compared with a hydraulic control mode in the prior art, automation and remote control of the control process can be achieved easily; in addition, a hydraulic rubber pipe is replaced by the electric wire, so that the assembly difficulty can be reduced, the maintenance is simple, the rectification is convenient, and the assembly flexibility and the error-tolerant rate are improved.
本发明公开了一种滑移装载机电液行走系统及控制方法，涉及工程机械技术领域，控制方法包括：获取手柄的动作信息；根据手柄的动作信息控制排量控制阀动作、并控制输出至排量控制阀的控制电流；通过排量控制阀控制行走主泵的排量及出油口出油，以控制第一马达和第二马达的转速及转向。本发明中的控制方法通过电控方式控制排量控制阀的动作及控制电流，相比于现有技术中液控的控制方式，有利于实现控制过程的自动化及远程控制；另外，通过电线代替液压胶管，可以降低装配难度，使维修简单、整改方便，提高了装配的灵活性和容错率。
