摘　　要：20世纪80年代,液压传动作为大功率的牵引传动还很不完善,随着时间的推移,在世界范围内新技术革命对传统机械工业的改造与渗透日益加强,使得液压技术得到了迅速发展。在工程机械行业内,大量不以牵引功能而以恒速调节为主要功能的路面与压实机械几乎全面采用了液压传动和液压控制技术,同时对于以牵引功能为主的铲土运输机械。The hydraulic driving as a high-powered pulling drive was still unperfected in the 1980's. As time goes on, because the reform and permeation of new technology revolution all of over the world to the traditional machinery industry are strengthened day by day, the hydraulic technology is developing rapidly. In the construction machinery industry, a great many of road building machines and compactors, not taking the pulling function but the constant-rate adjustment as the main function, almost overall have adopted the hydraulic driving and hydraulic control, and at the same time, the scraping and transporting machines with major function of pulling have the trend to the hydraulic driving to replace the conventional driving of hydraulic and mechanism, and specially for the small-and medium-duty machines with power of less than 200kW, the application of electronic-hydraulic control and the research into intelligence control have achieved certain successes. The continuous development of hydraulic and computer control technologies gives the perfect characteristics and great vitality to the hydraulic driving technology.
