Multistage planetary transmission i.e. automatic transmission, for e.g. passenger car, has planetary gear set with bar connected with output shaft, which is connected with another planetary gear set

摘要

The transmission has a planetary gear set (P2) with a bar that is connected with a drive shaft (1). A shaft (5) is detachably connected with another shaft (7), which is connected with a ring gear of the planetary gear set, by a coupling (57). The latter shaft is detachably connected with a third shaft (8), which is connected with a sun gear of another planetary gear set (P3) by another coupling (78). A bar of the latter planetary gear set is connected with an output shaft (2) that is connected with a third planetary gear set (P4).
