Multistage gearbox, especially automatic gearbox for motor vehicle, has 4 planetary sets, at least 8 rotary shafts, at least 6 shift elements, whose selective engagement causes different transmission ratios between drive, driven stages

摘要

The gearbox has drive (An) and driven (Ab) stages arranged in a housing (G), four planetary sets (P1-P4), at least eight rotary shafts (1-8) and at least six shift elements (O3-O5), including brakes and couplings whose selective engagement causes different transmission ratios between the drive and driven stages.
