摘要
静液传动液压系统可实现履带车辆无级变速、平稳转向,提高车辆机动性、同时大幅提高传动系统功率密度,在车辆传动系统中广泛应用。介绍了国内外静液驱动系统的应用及发展趋势,并通过分析和梳理,归纳了变量泵-变量马达控制理论发展中的一些重要问题,进一步探究变量泵-变量马达系统的发展趋势。
It is the tendency of vehicle transmission that adopting the hydrostatic transmission for hlgh-speed tracked vehicle be- cause of its stepless speed regulation, stepleas steering, high motility and high power density improved, hydrostatic transmission hy- draulic system has been rapidly appliedl The application and development trend of overseas and domestic hydrostatic transmission sys- tem were described, and some important issues in development of control theory for the variable pump-variable motor were summarized by means of analysis and classification. Finally, the development trends in the variable pump-variable motor system were discussed.
