摘要：
A multi step transmission comprising planetary gearsets (P1, P2, P3, P4), shafts and shift elements. The sun gear of gearset (P1) couples drive shaft (1). The carrier of set (P1) couples shaft (3), which couples housing (G) via brake (03), shaft (1) via clutch (13) and shaft (6) via clutch (36). Shaft (6) couples the ring and sun gear of gearsets (P2 P3) respectively, and, via clutch (68), shaft (8), which couples the carrier of gearset (P4). Shaft (1) couples the carrier of gearset (P4). Shaft (7) couples the ring gear of gearset (P1) and the carrier of set (P2). The sun gear of gearset (P4) couples shaft (4), which couples housing (G) via brake (04). The ring gear of gearset (P3) couples shaft (5), which couples housing (G) via brake (05). Output shaft (2) couples the carrier of gearset (P3) and the ring gear of gearset (P4).
