摘要
本文中将机械创新性设计方法应用于单电机并联混合动力传动系统的结构分析,以拓展混合动力汽车传动系统的结构。首先分析两种具有代表性的单电机并联混合动力汽车的传动结构,得到其机械拓扑结构。通过机械创新性设计方法,应用一般化规则得到机械拓扑结构的运动链,根据其运动链构件和运动副的数目得到一般化运动链。采用特定化程序,从一般化运动链图找出满足设计约束的可行特定化运动链图谱,除去同构类型后得到12种可行特定化运动链,利用具体化规则转换为相应的行星轮系的机构简图。通过动力输入输出分配与运行模式分析,最终获得132种单电机并联混合动力汽车传动系统的可行结构。选取其中一种新构型,分析其6种基本运行模式下的能量流动,得到15种离合器与制动器的状态组合,验证了将机械创新方法应用于混合动力传动系统结构设计的可行性。
In this paper, the mechanical innovative design method is applied to the structural analysis ofsingle-motor parallel hybrid powertrain system for expanding the transmission system structure of hybrid electric vehi-cle. Firstly, two representative transmission structures of single-motor parallel hybrid electric vehicle are analysedwith their mechanical topology structure obtained. With mechanical innovative design method, the kinematic chainsof mechanical topology structure are obtained by applying generalization rules, and the generalized kinematic chainsare acquired according to the members of kinematic chain links and kinematic pairs. By adopting specific programthe feasible and specific kinematic chain map meeting design constraints is found from the generalized kinematicchain plots, and after eliminating those with same configurations, 12 feasible and specific kinematic chains are ob-tained, which are then converted into corresponding schematic diagram of plenary gear set by using concretizationrules. Finally, through the analyses on power input / output distribution and operation modes, 132 feasible structuresfor the transmission system of single-motor parallel hybrid electric vehicle are obtained, from which a new configura-tion is chosen with its energy flows in six basic operation modes analyzed to get 15 combinations of clutch and brakestate, verifying the feasibility of applying mechanical innovative design method to the structural design of hybridpowertrain system.
