摘　　要：阐述了一种能够解决负力拖动机械系统制动问题的液压制动系统的核心元件———刹车变量泵及其模拟试验系统 .测试结果表明 ,两点式刹车变量泵具有制动力矩突变特性 ,通过降低变量机构的开启压力和提高最终制动压力即能够实现根据反馈信号大小自动调整制动力矩 ,使被制动机械系统可靠、平稳。A kind of braking variable pump acted as the core component of hydraulic braking system, which can settle load drag mechanical systems braking problems, and its simulation test system are introduced.The test results indicate that reducing open pressure of variable mechanism and raising final brake pressure can automatically regulate brake torque according to the value of feedback signal to achieve the reliable, smooth and swift stall of passive braking system, although two pointed braking variable pump have the sudden variable property of brake torque.
