摘　　要：对于电驱动履带车辆传动机构,基于双独立式方案的中间功率耦合行星传动机构可以实现转向再生功率的高效传递。针对由两个行星排组成的功率耦合机构,研究了能实现转向再生功率传递的构型特征。为了进行一般性的研究,提出一种新的行星传动的图论模型,这种模型使得构件的属性能用其特征参数表达。对于具有两个运动自由度的功率耦合机构,其拓扑结构只有一种类型。根据输入和输出的构件的选择,可以分为两个子类。针对这两类构型进行理论分析,得出了实现转向再生功率传递的参数特征。根据参数特征,可以得到实际构型。仿真结果与理论分析吻合。分析方法可以进一步用来分析由多个行星排组成的功率耦合机构,为履带车辆传动机构的构型设计提供理论依据。For the transmissions of tracked vehicles, the power coupled planetary mechanism can achieve the transfer of steering regenerative power. In this paper, the configuration characteristics of the power coupling mechanism composed of two planetary gear trains that can realize the steering regenerative power transfer are studied. In order to carry out general research, this paper presents a new graph theory model to represent planetary transmission,which makes it possible to represent the properties of the component with its characteristic parameters. For the power coupling mechanism with two kinematic degrees of freedom, the topology contains only one type. According to the selection of the input and output components, the configurations can be divided into two sub-types. Based on the analysis of the two sub-types, the characteristics of the parameters to achieve the transfer of the steering regenerative power are presented. According to the analysis results, the actual configurations are obtained. The simulation results are consistent with the theoretical analysis.
