混合动力客车三源助力转向系统研究与应用

Research and Application of Three Source Powersteering System for Hybrid Electric Bus

传统客车转向系统助力是由发动机驱动转向助力泵提供油压为转向系统提供助力。通过对11米混合动力客车三源助力转向系统的分析,找出新能源客车尤其是混合动力客车转向系统存在的区别,提出三源助力转向系统控制策略,有效解决了方向盘不平顺问题。

The power assist of the traditional passenger car steering system is provided by the engine-driven power steering pump to provide oil pressure for the steering system.Through the analysis of the three-source power steering system of 11-meter hybrid buses,the differences in the steering systems of new energy buses,especially hybrid buses,are found,and the three-source power steering system control strategy is proposed,which effectively solves the problem of steering wheel irregularities.
