Abstract:
A transmission having gearsets (RS1-RS4), shafts (1-8) and shifting elements (A-E). A carrier of gearset (RS4) and an input shaft forming shaft (1), a carrier of gearset (RS3) and an output shaft form shaft (2), sun gears of gearsets (RS3, RS4) form shaft (3). A ring gear of gearset (RS1) forms shaft (4). Ring and sun gears respectively of gearsets (RS2, RS1) couple as shaft (5), a carrier of gearset (RS1) and a ring gear of gearset (RS3) form shaft (6), sun and ring gears respectively of gearsets (RS2, RS4) couple as shaft (7). A carrier of gearset (RS2) forms shaft (8). Located in the flow of power: elements (A, B) are respectively between shafts (3, 4) and a housing, element (C) between shafts (5, 1), element (D) between shafts (8, 2) or (8, 6) and element (E) between two of shafts (5, 7, 8).
