The invention relates to the technical field of engineering machinery, in particular to a new energy mine truck emergency steering system and an emergency steering method. The system comprises a main pump, the main pump is connected with a main oil inlet, the main oil inlet is communicated with the front end of a sliding cavity after passing through a main one-way valve, the system further comprises an emergency pump, the emergency pump is connected with an emergency oil inlet, the emergency oil inlet is communicated with the side portion of the sliding cavity after passing through an emergency one-way valve, and the rear end of the sliding cavity is communicated with an oil outlet; a sliding pipe is slidably connected into the sliding cavity, a reset device is arranged between the sliding pipe and the sliding cavity, a baffle is arranged on the inner side of the sliding pipe, a baffle oil hole is formed in the baffle, a sensor is installed at the front end of the inner side of the sliding cavity, and when the sliding pipe is located at the stroke front end, the sliding pipe can make contact with the sensor. When the main pump works abnormally, the sliding pipe is located at the front end of the stroke under the action of the reset device, the sensor sends a signal to the emergency pump ESP, and the emergency pump is started. After the main pump fails, power can be provided for the steering mechanism through the emergency pump.
本发明涉及工程机械技术领域,具体的,涉及一种新能源矿卡应急转向系统及应急转向方法。该系统包括主泵,主泵连接有主进油口,主进油口经过主单向阀后与滑动腔前端相连通,还包括应急泵,应急泵接有应急进油口,应急进油口经过应急单向阀后与滑动腔侧部相连通,滑动腔后端与出油口相连通;滑动腔内滑动连接有滑动管,滑动管与滑动腔之间具有复位装置,滑动管内侧具有挡板,挡板上开设有挡板油孔,滑动腔内侧前端安装有传感器,当滑动管位于行程前端时,滑动管能够与传感器相接触。主泵工作不正常时,滑动管在复位装置的作用下位于行程前端,传感器向应急泵ESP发出信号,启动应急泵。主泵失灵后,可以依靠应急泵为转向机构提供动力。
