摘要

自动变速技术是拖拉机传动系控制的关键技术,也是提高拖拉机工作效率的有效途径。综述了拖拉机自动变速器在国内外的应用现状,并对目前国外大中功率拖拉机上广泛应用的动力换挡自动变速器和无级变速器的传动系统、液压系统、控制策略以及换挡换段品质控制技术等进行了深入分析。根据当前变速器换挡控制的发展趋势,对拖拉机变速器自动控制技术未来的发展研究方向进行了展望。

Abstract

The automatic transmission technology is the key technology of tractor transmission system control,is also an effective way to improve the efficiency of the tractor working.The application status at home and abroad is summarized,and the deeply analysis of transmission system,hydraulic system,control strategy,shift quality control technology of power shift transmission and continuously variable transmission which widespread use on the foreign large and medium power tractors at present are carried out.The development and research direction of automatic control technique of transmission on tractor is forecasted based on the development trend of transmission gearshift control.
