摘要

The transmission has a drive shaft (1), an output shaft (2), four negative planetary gear sets (P1-P4) that are arranged in a housing (G), and six rotatable shafts (3-8). A sun gear of the second planetary gear set is connected to the housing via a brake (04). A ring gear of the third planetary gear set is coupled to the housing. The output shaft is connected to a bar of the third planetary gear set and a ring gear of the fourth planetary gear set. The first planetary gear set is interlocked by locking of a clutch (13).
