Planetary multi-stage gearbox, especially vehicle automatic gearbox, has shafts connected to sun wheels or webs of planet sets, coupled to housing by brakes, reversibly coupled together by couplings

摘要

The gearbox has a drive shaft and a driven shaft in a housing, three planetary sets, at least 6 rotatable shafts (1-6) and at least 5 shift elements (03,04,13,16,45) with brakes and/or couplings for selective engagement resulting in different gear ratios between the shafts with 6 forward and 1 reverse gears. It has shafts connected to sun wheels or webs of planet sets, coupled to the housing by brakes and reversibly coupled together by couplings.
