摘　　要：功率分流无级变速装置能够把无级变速器的连续性和机械变速装置的高效性结合在一起。主要分析带有飞轮储能器的输入耦合功率分流无极变速装置特性,研究带有飞轮储能器的功率分流器的能量回收机制和传动系能量回收性能,使其适用于混合动力轮式装载机。与标准功率分流变速装置相比,仿真结果表明:混合动力功率分流变速装置能节约更多的能量。Power split stepless speed change device integrates the continuity of the CVT and the efficiency of mechanical transmis- sion together. The performance of the input coupling power split stepless speed change device with a flywheel energy storage was ana- lyzed. The energy recovery mechanism of power split with the flywheel energy storage was researched, the energy recovery performance of drive system was discussed to make it suitable for hybrid wheel loader. Compared with standard power split transmission, the simula- tion shows that hybrid power split transmission has higher saving energy.
