摘要
基于杠杆法对双排并联行星齿轮机构(Planetary gear mechanism,PGM)构件进行节点匹配,获得PGM连接方案;对单电机变速器(Single motor transmission,SMT)的发动机、电机及接合元件布置进行分析,获得接合元件数少、发动机及电机驱动模式挡位数多的布置方案。根据现有双排并联PGM变速器传动比范围对PGM连接方案进行筛选,得到17种满足传动比要求的SMT构型。任选一种SMT构型,将其拓扑化后进行工作模式及功率流向分析,得出其能实现发动机驱动、电机驱动、混合驱动、行车发电、制动发电及停车发电等6种工作模式,且各工作模式无循环功率。
Based on the lever method,the possible connection schemes are obtained via matching the components of leverage node of double row parallel planetary gear mechanism(PGM).A layout scheme with less linking elements and more gears is achieved by analyzing the arrangement of engine,motor and linking elements.According to the gear ratio range of existing double row parallel PGM transmissions,the PGM connection scheme is screened,and finally 17 configurations of SMT are obtained.Arbitrary selected a configuration of SMT and topologized,the operation mode and power flow of the configuration of SMT are analyzed.It is obtained that not only can it realize engine driving,motor driving,hybrid driving,driving power generation,braking power generation and parking power generation working modes,but also is no cycle power in each working mode.
