摘　　要：目前,国内装载机普遍采用气顶油钳盘式制动系统,全液压制动属于较为新式的制动系统。论述了全液压制动系统的组成及工作原理,就全液压制动系统容易出现的以下三种问题:制动踏板反弹及制动剧烈,无点刹;行走过程中突然失去动力;充液阀阀芯卡死、制动泵炸裂进行了分析,并提出了具体的改进方案。改进后效果良好,不再出现上述问题。Air-on-oil, caliper disc brake system is widely used on domestic loaders. Fully hydraulic brake system is a kind of new type brake system. Its composition and work principle are explained. Three problems existing in fully hydraulic brake system, brake pedal rebound and sudden braking, no inching braking; sudden power failure during traveling; spool seizure in fluid feeding valve and brake pump blasting, are analyzed. Concrete improvement measures are suggested. After improvement, all above problems never occurr again.
