| 摘 要： | A761E是丰田轿车上的6速电控自动变速器,由1个单排双级行星齿轮机构和2个单排单级行星齿轮机构组成,其内部共有12个换挡执行元件,这3排行星齿轮机构可产生6个前进挡和1个倒挡,根据不同挡位各执行元件的状态,可逐个分析各挡动力传动路线,通过对行星齿轮机构建立运动方程和分析约束条件,可逐个进行各挡传动比的计算.动力传动的分析及计算是自动变速器维修的理论基础和故障判断依据.

| Abstract: | A761E is the six-position automatic transmission in Toyota.It is composed of one single-row two-stage planetary gear mechanism and two single-row single-stage planetary gear mechanism.Inside,there are 12 position shift execution components.These three rows of planetary gear mechanism are able to generate 6 forward positions and one reverse gear position.The each power transmission route is analyzed according to the different position status of each execution component and the transmission ratio of each position is calculated by establishing motion equation and analysis restriction conditions for the planetary gear mechanism.Analysis and calculation of power transmission is the theoretical basis and fault judgment basis of maintenance for automatic transmission. |
