发明名称 9-Speed Planetary Gearbox
摘要 A transmission has one drive shaft, one output shaft, one housing, a first planetary gear set, a second planetary gear set, and a third planetary gear set, six shift elements, including a first brake, a second brake, a first clutch, a second clutch, a third clutch, and a fourth clutch. The shift elements selectively actuated, by which nine forward gears and one reverse gear are realized through different transmission ratio relationships between the drive shaft and the output shaft. Each planetary gear set features at least one sun gear, one planetary gear, one planetary carrier, and one ring gear. The drive shaft and the output shaft are arranged in a manner axially offset to each other, and the drive shaft is connectable to the sun gear of the first planetary gear set through the first clutch and to the first brake and the ring gear of the second planetary gear set through the second clutch. The ring gear of the second planetary gear set and the first brake are also connected to each other.
