摘　　要：在井下无轨车辆中，ＵＦＤ－２型井下多功能服务车首次采用ＤＡ自动变速控制的双变量静液压机绒传动，它能在各种负载工况下自动变速和自动变矩。本文对该车的行走－制动液压系统和转向－工作液压系统进行了分析和研究；阐明了ＤＡ自动变速控制原理、功能与特点；经试验表明，这两种液压系统设计是成功的，技术先进，安全可靠，性能良好。In trackless vehicles,the first use of two-variable static hydraulic drive withDA automatic transmission control was made in Madel UFD -2 underground multi-func-tion service vehicles, which can conduct automatic transmission and torque conversion onvarious loading conditions. The author analyzed the running-braking hydraulic pump andthe steering-operating hydraulic pump of the undergroud multi-function service vehiclesand explicated the mechanism,functions and characteristics of DA automatic transmissioncontrol.The test showde that the two kinds of hydranlic systems are successful in designand advanced in technology,with safety and reliability, and good performance.
