摘要

主要针对串联式液压混合动力车的液压系统进行设计和分析。该液压系统利用蓄能器回收刹车动能,并在车辆再次加速时释放,从而达到能源回收再利用的目的。该系统的刹车动能回收效率为73%,能量使用效率为32.8%;进一步分析比较阀控液压系统与泵控液压系统对刹车动能回收与能量使用效率的影响,泵控液压系统对于能量使用效率上可提升13.6%。
        The hydraulic system of a series hydraulic hybrid vehicle was designed and analyzed. This hydraulic system recovers and stores the breaking kinematic energy in an accumulator, and releases the energy during vehicle acceleration. In this way, energy recovery and reuse can be achieved. The analysis results demonstrate a braking energy recovery efficiency is 73% and overall vehicle energy efficiency is 32.8% for the original design. Furthermore, the effect that the hydraulic valve controlled system and hydraulic displacement controlled system have on the efficiency of breaking kinematic energy recovery as well as energy use were analyzed and compared. The conclusion is that the overall vehicle energy efficiency can further improve by 13.6% for the hydraulic displacement controlled system.
