Abstract:
A transmission having gearsets (P1-P4), shafts (1-8) and shifting elements (03, 04, 05, 48, 67, 78). Shaft (1) couples an input and carrier of gearset (P1), shaft (2) couples the output and carriers of gearsets (P3, P4), shaft (3) couples the ring gear of gearset (P2) and the sun gear of gearset (P1), shaft (4) couples the ring gear of gearset (P3) and the sun gear of gearset (P4), shaft (5) couples the ring gear of gearset (P4), shaft (6) couples the sun gear of gearset (P2) and the ring gear of gearset (P1), shaft (7) is connected to the sun gear of gearset (P3), and shaft (8) is connected to the carrier of gearset (P2). Shafts (3, 4 and 5) can each engage housing (G) by way of respective brakes (03, 04, 05), clutches (48; 67; 78) can couple, respectively, shafts (4, 8; 6, 7; 7, 8).
