中大拖电液提升控制系统分析

Analysis of electrohy-hydraulic hitch control system of large-medium tractor

系统分析了当前主流电液提升系统的技术特点及控制原理,提出了国内主流电液提升控制系统提升改进的方向,为电液提升控制系统的设计提供了建设性意见。同时对其主要控制元件的技术发展思路进行了对比分析,为后期核心液压元件的开发提供了技术参考。

This paper systematically analyzes the technical characteristics and control principle of the current mainstream electrohyhydraulic hitch control system,and puts forward the improvement direction of the domestic mainstream electrohy-hydraulic hitch control system,which provides constructive suggestions for the design of the electrohy-hydraulic hitch control system.Based on comparison and analysis of technical development direction of main control components,this paper provides a technical reference for the later development of hydraulic control valves.
