摘　　要：转向液压系统是轮式装载机中最为重要的液压系统之一,该系统中转向泵在高速状态下的功率损失比较大,液压系统的功率损失使得液压油的温度升高,从而带来一系列不利影响。介绍装载机负荷传感转向液压系统的优先合分流回路,并对各种优先回路的形式、特点进行分析阐述。The hydraulic steering system is one of the most important hydraulic systems for the wheel loader, however, which steering pump in the system would get greater loss in power under high speed conditions that would bring high the oil temp and come with a serial defects. The text goes further to introduce the load sensing steer hydraulic system and the priority circuits for combination and separation purpose, together with detailed descriptions on types and features of priority circuits respectively.
