摘　　要：分析现有汽车液驱混合动力系统,提出了一种基于行星齿轮系动力分配机构的闭式液驱混合动力系统的方案,介绍了系统的基本原理和动能传递过程,并对制动过程中动能的传递进行数学模型建立和仿真及实验分析。结果表明,制动过程能量回收效果良好,系统设计和元件参数的计算合理。该研究结果对于以后的液驱混合动力技术的研究具有一定的参考价值。Basing on an analytical of hydraulic drive hybrid power system, a new closed hydraulic drive hybrid power system is proposed. The basic principle of the system and the transfer process of the kinetic energy are introduced, and the mathematical model of the transfer of the kinetic energy during braking is established and the simulation analysis is carried out. The result shows that the braking process is stable, the energy recovery is effective, the design of the system and the calculation of the ele- ment parameters are reasonable. The result of the study has reference value to the study of the hybrid technology in the future.
