用高压油直接传递动力称为静液压传动,其特征是流量小压力大。静液压驱动系统的主要部件是液压泵、操纵调控装置和液压马达。本文就静液压传动装载机的特点以及传统液力传动装载机的比较作一介绍。 Direct transmission of high-pressure oil is called static hydrostatic transmission, which is characterized by small flow pressure. The main components of hydrostatic drive systems are hydraulic pumps, steering controls and hydraulic motors. This paper introduces the characteristics of hydrostatic loader as well as the comparison of traditional hydrodynamic loader.
