Abstract:
A transmission having input and output shafts, gearsets (RS1-RS4), shafts (1-8) and elements (A-E). Carriers of gearsets (RS4, RS3) are respectively connected to the input and the output forming shafts (1, 2). Sun gears of gearsets (RS1, RS4) are coupled forming shaft (3). The ring gear and a carrier respectively of gearsets (RS1, RS2) form shafts (4, 8). Ring gears of gearsets (RS2, RS4) respectively couple sun gears of gearsets (RS3, RS2) forming shafts (5, 7). A carrier of gearset (RS1) and a ring gear of gearset (RS3) are connected forming shaft (6). In the power flow, elements (A, B) are respectively arranged between shafts (3, 4) and a transmission 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).
