Document Type and Number:
Japanese Patent JP2008531954
Kind Code:
A
Abstract:
The 8-gear multi-step transmission comprises a drive input shaft (AN), a drive output shaft (AB), four planetary gearsets (RS1, RS2, RS3, RS4), eight rotary shafts (1, 2, 3, 4, 5, 6, 7, 8) and five shift elements (A, B, C, D, E). An internal gear (HO1) of the first planetary gearset (RS1) and the drive input shaft (AN) are connected to one another as the first shaft (1). A carrier (ST4) of the fourth gearset (RS4) and the drive output shaft (AB) are connected to one another as the second shaft (2). A sun gear (SO2) of the second gearset (RS2), and a sun gear (SO3) of the third gearset (RS3) are connected to one another as the third shaft (3). An internal gear (HO2) of the second gearset (RS2) forms the fourth shaft (4). An internal gear (HO3) of the third gearset (RS3) forms the fifth shaft (5). A carrier (ST2) of the second gearset (RS2) and an internal gear (HO4) of the fourth gearset (RS4) are connected to one another as the sixth shaft (6). A sun gear (SO1) of the first gearset (RS1) and a sun gear (SO4) of the fourth gearset (RS4) are connected to one another as the seventh shaft (7). A carrier (ST1) of the first gearset (RS1) and a carrier (ST3) of the third gearset (RS3) are connected to one another as the eighth shaft (8).
