Power Loss Analysis of Bent Axis Motor with Zero Displacement

弯轴柱塞马达常用来作为静液压行走驱动的主要执行元件,部分柱塞马达具有零排量的结构,便于在多马达系统中采用零排量功能将马达切出系统,该文通过分析弯轴柱塞马达在不同排量与转速下的功率损失数据,特别在零排量的工况下,以工程机械常见的一泵四马达行走驱动系统为例,通过不同构建的驱动类型所产生的功率损失对工程机械系统总功率损失的影响,经过试验数据对比,提出降低系统总功率损失并提高工程机械总运行效率的系统设计。

Bent axis motor normally applied as hydrostatic propel for off highway machines.Some of motor with zero displacement will be controlled at zero position when needed.Power loss at different displacement and working speed of bent axis motor was analyzed.Especially,when motor worked at zero displacement,one pump and four motor propel system,different system design have big impact on machine total power loss.Based on the test data analysis,proposed the best efficiency means least power loss solution for off highway machine propel system.
