Abstract:
The 8-gear transmission comprising an input shaft (AN), an output shaft (AB), four planetary gearsets (RS1, RS2, RS3, RS4), eight rotary shafts (1, 2, 3, 4, 5, 6, 7, 8) and five shifting elements (A, B C, E, E). The first shifting element (A) is arranged within the power flow between the third shaft (3) and a housing (GG) of the transmission, the second shifting element(B) is arranged within the power flow between the fourth shaft (4) and the housing (GG), the third shifting element (C) is arranged within the power flow between the first and the fifth shafts (1, 5), the fourth shifting element (D) is arranged within the power flow between the fifth and the eighth shafts (5, 8), and the fifth shifting element (E) is arranged within the power flow between the fifth and the seventh shafts (5, 7).
