摘　　要：简要介绍了车辆静液压储能传动这一新型动力传动系统的基本组成、工作原理及其特点，详细分析了系统中关键元件之一的储能元件——气囊式蓄能器的各参数之问的关系以及蓄能器的充气容积、有效容积和压力、多变指数等参数的变化对车辆制动能量回收以及对车辆性能的影响，并以某型公共汽车为例，通过分析计算和实验得出了系统的能量回收率为38．46％-61．55％，该车具有良好的使用性和经济性及实际应用前景。The compose, working principle and of a new hydrostatic transmission system were introduced, the relationship between parameters： polytropic exponent, charge volume, effective volume and pressure of accumulator, and influence on energy callback and characteristics of vehicle was analyzed, and energy callback efficiency was calculated with a bus - example. The experimental results are 38.46% ～61.55% and denpend on accumulator volume. Research shows that the new vehicle with electronic control and hydrostatic drive has advantageous economy and other features and is in good prospect of future development.
