目前国内大中型装载机采用的全液压转向系统有以下三种形式。第一种是用一台小排量(200mL／rpm 以下)普通转向器,通过流量放大器来放大流量。这是最早开发的大排量转向系统,其最大的不足是需要两种元件组合, 需要空间大、管路长、接口多、能量损失比较大,同时造价比较高,维修保养困难。进口机型大多采用此种形式。 At present, the full hydraulic steering system used in large and medium-sized domestic loaders has the following three forms. The first is to use a small displacement (200mL / rpm below) ordinary steering gear, through the flow amplifier to amplify the flow. This is the earliest development of large displacement steering system, the biggest drawback is the need for two components, the need for space, long pipe, interface, more energy loss, while higher cost, maintenance difficulties. Most imported models in this form.
