摘　　要：并联双排行星齿轮机构组成的独立机构是复杂变速器的基本单元,传动比要以整体计算。提出了基于杠杆法利用单级和双级单排行星齿轮机构的,3节点统一模型设计并联双排行星齿轮机构的方法,并图解其原理。并以此为基础设计出一种并联双排行星齿轮机构(单级+双级CC-SS)对应的新型变速器,并与经典变速器A341E(单级+单级CR-SS)、4T65E(单级+单级CR-RC)、AG4(单级+单级CC-RR)以及某轿车变速器(单级+双级CC-SS的另一种方案)相比,该变速器具有传动比幅度较大、速比阶跃波动小以及换挡元件最少等特点,总体上优势明显。As the basic unit of complex transmission,two-row parallel planetary gear mechanism needs to be considered as whole in transmission ratio computation. According to the design requirements of vehicle automatic transmission,the design procedure for two-row parallel planetary gear mechanism is proposed based on the lever method using 3-node unified single-row single-stage and two-stage model,and the principle are illustrated by diagram. A new type of two-row parallel planetary gear mechanism（ single-stage and two-stage CC-SS） is designed and compared with the classical transmission A341 E（ single-stage and single-stage CR-SS）,4 T65 E（ single-stage and single-stage CR-RC）,AG4（ single-stage and single-stage CC-RR） and the transmission（ different case of single-stage and two-stage CC-SS） from a certain car,results show the new type of gear mechanism overall has obvious advantages of larger transmission ratio range,small transmission ratio step and least shifting components.
