Abstract (en)

[origin: WO2014060141A1] The invention relates to a multi-stage transmission comprising four planetary gear wheel sets (P1, P2, P3, P4), eight rotatable shafts (1, 2, 3, 4, 5, 6, 7, 8) and six shifting elements (03, 04, 05, 15, 17, 48), wherein the sun gear of the first planetary gear wheel set (P1) is connected to the fifth shaft (5), which can be connected to the drive shaft (1) by a first coupling (15) and can be coupled to the housing (G) via a third brake (05), wherein the drive shaft (1) can be connected via a second coupling (17) to the seventh shaft (7), connected to the web of the fourth planetary gear wheel set (P4) and the ring gear of the third planetary gear wheel set (P3), and is connected to the sun gear of the second planetary gear wheel set (P2), wherein the sixth shaft (6) is connected to the ring gear of the first planetary gear wheel set (P1), the web of the second planetary gear wheel set (P2) and the ring gear of the fourth planetary gear wheel set (P4) and the third shaft (3) is connected to the sun gear of the third planetary gear wheel set (P3) and the sun gear of the fourth planetary gear wheel set (P4) and can be coupled to the housing (G) via a first brake (03), wherein the fourth shaft (4) is connected to the web of the first planetary gear wheel set (P1), can be coupled to the housing (G) via a second brake (04) and can be connected via a third coupling (48) to the eight shaft (8), which is connected to the ring gear of the second planetary gear wheel set (P2), and wherein the drive shaft (2) of the transmission is connected to the web of the third planetary gear wheel set (P3).
