Multistage transmission e.g. automatic transmission, for e.g. passenger car, has brake and clutches engaged to produce different transmission ratios between drive shaft and output shaft that is connected with carrier of planetary gear train

摘要

The transmission has a brake (03) and clutches (13, 16, 17, 28, 34) engaged to produce different transmission ratios between a drive shaft and an output shaft (2), where the drive shaft is detachably connected with a shaft (6). Another shaft (5) is connected with an internal gear of a first planetary gear train (P1) and a planetary carrier of a second planetary gear train (P2). An internal gear of a third planetary gear train (P4) is coupled to housing (G). The shaft (2) is connected with an internal gear of a fourth planetary gear train (P3) and a planetary carrier of the third gear train.
