Planetary type multi-stage gear transmission i.e. automat transmission, for e.g. passenger car, has output shaft connected with bars of two of four planetary gear sets, where output shaft is coupled to housing

摘要

The transmission has a drive shaft, an output shaft (2), six rotatable shafts (3-8) and four planetary gear sets (P1-P4), which are arranged in a housing (G). The third shaft is connected with a sun wheel of a third planetary gear set and a sun wheel of the fourth planetary gear set. The third shaft is coupled to the housing by a brake (03). The output shaft is connected with a bar of the third planetary gear set and a bar of the first planetary gear set, where the output shaft is coupled to the housing.
