摘　　要：为掌握不同车辆传动系统之间的关系,有必要从本质上对其进行分类,以发现内在规律。通过分析大量的传动系统,基于所提出的传动系统衍生规则,定义了传动系统传动比并分析了其动态过程功率损失,进而从传动系统传动比、功率传递路线、传动介质和动力传动自由度对其进行了研究并划分为四种类别。研究发现了不同类别之间的关系,该关系与传动系统的演变密不可分。同时定义了既能反映系统固有属性,又能表现其区别的特征名称,发现了传动系统会向无级、复合传动、多功率流及多自由度方向演变发展。For the purpose of grasping the relationship between different drivelines of vehicle,it is necessary to classify the drivelines from the essence and to discover the intrinsic laws.Based on the derivation rules of the driveline that were proposed,the driveline drive ratio was defined and the power losses in the dynamic process were analyzed through many different vehicle drivelines.And the drivelines were classified into four categories according to driveline drive ratio,power flow route,driving medium and degree of freedom of power-train respectively.It was founded that there were certain relationships between different categories and the relationships were close with the evolvement of the driveline.The characteristic name of driveline was defined,which can reflect the intrinsic properties of the system,and also can show the difference between different systems.In addition,it was concluded that the driveline would evolve into the stepless and complex transmission,multiple power flows and multiple degrees of freedom.
