Multi-stage planetary transmission i.e. automatic transmission, for use in passenger car, has clutch detachably connecting shaft to drive shaft or another shaft to drive shaft or latter shaft to former shaft

摘要

The transmission has four planetary gear sets (P1-P4) arranged in a housing (G), where one of the planetary gear sets is designed as a plus planetary gear set and the other planetary gear sets are designed as minus-planetary gear sets. A shaft (8) is connected to webs of the second and third gear sets. An output shaft (2) is connected to a web of the fourth gear set. A drive shaft (1) is connected to an internal gear of the third gear set. A clutch (17) detachably connects another shaft (7) to the drive shaft or the former shaft to the drive shaft or the latter shaft to the former shaft.
