随着机械生产能力的提高,液压转向系统的功率占整机功率的比重越来越大(如装载机转向系统的功率占整机功率近30%)。因此,转向系统的节能问题已提到议事日程。国外Eaton、Dafoss等公司已将节能的负荷传感全液压转向器和先导阀列入其产品系列,供用户选用。由负荷传感全液压转向器和先导阀组成的负荷传感系统主要用于装载机、起重机、叉车、 With the improvement of mechanical productivity, the power of hydraulic steering system accounts for an increasing proportion of the total power (eg, the power of the steering system of the loader accounts for nearly 30% of the total power of the whole machine). Therefore, energy-saving steering system has been referred to the agenda. Foreign Eaton, Dafoss and other companies have energy-saving load sensing hydraulic steering gear and pilot valve included in its product line for users to choose. The load sensing system consists of load sensing hydraulic steering gear and pilot valve is mainly used in loaders, cranes, forklifts,
