摘　　要：提出基于两段液压机械传动的储能传动方案。根据基本市区循环工况表和发动机的万有特性,提出了储能式液压机械无级传动车辆起步加速过程在液压机械工况功率的计算方法,进行了储能式两段液压机械传动与液压机械无级传动车辆的燃油经济性分析,得出了车辆的节油率。The scheme of energy-reserving hydro-mechanical transmission was put forward. Based on the duty cycle table in city and engine characteristic map, the method of calculating duty power of hydro-mechanical machinery during speedup process at startup of vehicles using energy-reserving hydro-mechanical stepless transmission was proposed, and the fuel economy characters of vehicles u- sing two-range energy-reserving hydro-mechanical transmission and hydraulic-mechanical stepless transmission were analyzed. The rati- o of saving fuel of vehicle was educed.
