基于力士乐DA液控的静液压驱动系统较液力传动有明显的优势,但这种通过截流的方式实现转速相关控制的最大问题是受温度影响较大,由此导致其在寒冷地区的驱动性能与温热地区有较大差距。在保持静液压驱动系统基本优点不变的基础上,采用配置合理的电控系统能有效提高设备的操控性能、作业效率以及驱动系统与发动机的匹配性能,同时可实现灵活的个性化定制功能。本文介绍一种应用在静液压驱动装载机上基于CAN总线的电控系统。一、电控系统组成及原理1.总体结构系统的结构很大程度上决定了系统的生命力、方便性、通用性、灵活性和扩展性。基于系
Hydrostatic drive system based on Rexroth DA hydraulic control has obvious advantages over hydrodynamic transmission. However, the biggest problem of speed-dependent control by means of intercepting flow is that it is greatly influenced by temperature, which leads to its driving performance in cold area There is a big gap with warm area. On the basis of maintaining the basic advantages of hydrostatic drive system, adopting a properly configured electronic control system can effectively improve the handling performance, work efficiency, matching performance between the drive system and the engine, and meanwhile, can realize flexible and customized functions. This article presents an electronic control system based on CAN bus used in hydrostatic drive loaders. First, the composition and principle of electronic control system 1. Overall structure The structure of the system to a large extent determines the system’s vitality, convenience, versatility, flexibility and scalability. Based on the system
