Abstract:
A multi-stage transmission comprises planetary gearsets (P1, P2, P3, P4), shafts and shift elements. The carriers of gearsets (P1, P2) couple via shaft (4) which couples the sun gear of gearset (P3). The ring gear of the gearset (P1) couples the sun gear of gearset (P2) via shaft (8), which couples drive shaft (1) via clutch (18). The sun gear of gearset (P1) couples housing (G) by shaft (3) via brake (03), and shaft (1) via clutch (13). The ring gear of gearset (P2) couples housing (G) by shaft (5) via brake (05). The sun gear of gearset (P4) couples housing (G). Shaft (6) couples shaft (1) via clutch (16) and carrier of gearset (P3). Shaft (9) couples shaft (4) via clutch (49) and the ring gear of gearset (P4). Output shaft (2) couples the ring gear and the carrier respectively of gearsets (P3, P4).
