A multi-stage transmission comprising planetary gearsets (P1, P2, P3, P4), shafts, and shift elements. Gearsets (P1, P2) form a front -mounted gear gearset and gearsets (P3, P4) form a main gearset. The carriers of gearsets (P1, P2) are coupled via shaft (4) which couples a main gearset element. The ring gear of gearset (P1) couples the sun gear of gearset (P2) via shaft (8) that 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). Shaft (7) couples main gearset element, and, via brake (07), housing (G). Shaft (6) couples another main gearset element and, via clutch (16), shaft (1). The output shaft couples a further main gearset element. |
