摘要
多挡位的机械式自动变速机构，是由串联在一起的若干（n）个单级机械式变速机构构成的，挡位数的实现方法有两种：顺序变速和混序变速。前者是将各单级变速机构依次按顺序逐一自动变速完成的，实现的总挡位数为n＋1；后者则是将各单级变速机构进行交叉（混序）自动变速完成的，实现的总挡位数为2^n。与液力变矩器相比，多挡位机械变速机构的优点是具有较高的传动效率和较大的启动变矩系数。
The multi-shift mechanical speed changing mechanism consists of a number of （n） in series of single-stage mechanical speed-variable mechanisms. There are two methods of realizing shift change： in order or in mixing. The former method, in which there are numbers of n＋ 1 gears, is actualized automatically through arranging a number of single-stage speed changing mechanisms one by one. And the latter method, in which there are 2n gears, is actualized through arranging a number of single-stage speed changing mechanisms alternately （mixedly）. Compared with a hydraulic torque converter, the merits of the multi-shift mechanical speed change mechanism are higher in transmission efficiency and in startup torque-converting coefficient.
