液压调控技术是一门新兴技术,在技术、经济等方面均具有许多独特的优点,在农业生产、农产品加工制造机械设备中应用非常广泛且效果非常良好。本文介绍了基于液压技术的农用履带拖拉机液压驱动系统,对系统的总体方案和功能元件的优化选型进行了详细分析研究。农用拖拉机采用液压驱动行走系统,通过改变变量泵的排量实现拖拉机操作作业、转向、行走等功能的无级变速调控,具有非常良好的调控性能和节能经济性,在农业生产发展中具有非常大的应用前景。
Hydraulic control technology is an emerging technology, which has many unique advantages in terms of technology and economy. It is widely used and very effective in agricultural machinery and agricultural products processing and manufacturing machinery and equipment. In this paper, the hydraulic drive system of agricultural track tractor based on hydraulic technology is introduced. The overall scheme of the system and the optimization and selection of functional components are analyzed in detail. The agricultural tractor adopts the hydraulically driven walking system to realize the continuously variable speed regulation of tractor operation, steering and walking functions by changing the displacement of the variable displacement pump, has very good regulation performance and energy saving economy, and has very large development in agricultural production The application prospects.
