Abstract:
The ring gear of the second gearset (RS2) and the input shaft couple to form a first shaft (1). The carrier of third gearset (RS3) and the output shaft form a second shaft (2). The sun gears of first and fourth gearsets (RS1, RS4) form a third shaft (3). The carrier of first gearset (RS1) forms a fourth shaft (4). Sun gears of second and third gearsets (RS2, RS3) form a fifth shaft (5). Ring gears of first and third gearsets (RS1, RS3) form a six shaft (6). The carriers of second and fourth gearsets (RS2, RS4) form a seventh shaft (7). A ring gear of fourth gearset (RS4) forms an eighth shaft (8). In the direction of power flow, First and second shifting elements (A), (B) are located between shafts (3, 4) and a transmission housing, third shifting element (C) is between two of shafts (1, 5, 7), fourth and fifth shifting elements (D), (E) are between shafts (6, 8), (5, 8).
