摘　　要：提出一种应用液压变压器搭建液驱混合动力车辆的设计概念。在其工作原理的基础上建立相关数学模型,分析蓄能器的特性参数(有效容积、比能量和充放效率等)与液压变压器配流盘控制角之间的关系。在不同恒转矩制动工况下对直接能量回收和应用液压变压器间接蓄能器的能量回收进行仿真分析,得出不同变压比下的节能参数。A new design concept was proposed to build a hydraulic hybrid vehicle（HHV） using a hydraulic transformer（HT）. A mathematical model was established for HHV based on its working principle, and the relationships between the characteristic parameters of the accumulator（effective volume, specific energy, and charge-discharge efficiencies）and the port plate control angle of HT were analyzed. The energy regenerations of directly applied accumulator and indirectly applied accumulator through HT under different constant braking torque operating conditions were simulated, and the energy-saving parameters at different pressure ratios were obtained.
