Abstract (en)
[origin: WO2014000941A1] The invention relates to a multi-speed gearbox having four planetary gear sets (P1, P2, P3, P4), eight rotatable shafts (1, 2, 3, 4, 5, 6, 7, 8) and six shift elements (03, 04, 18, 38, 45, 46, 56, 57), wherein the sun gear of the first planetary gear set (P1) is connected to the input shaft (1), which is connected to the sun gear of the third planetary gear set (P3) and can be coupled to the eighth shaft (8) which is connected to the planet carrier of the fourth planetary gear set (P4) by means of a first clutch (18). The eighth shaft (8) can be connected to the third shaft (3) by means of a second clutch (38), which connects to the planet carrier of the third planetary gear set (P3) and can be coupled to the planet carrier of the first planetary gear set (P1) by means of a first brake (03), which is coupled to the housing (G). The fourth shaft (4) connects to the sun gear of the second planetary gear set (P2) and can be coupled to the planet carrier of the first planetary gear set (P1) by means of a second brake (04), and the seventh shaft (7) connects to the ring gear of the first planetary gear set (P1) and can be connected to the fifth shaft (5) which is connected to the ring gear of the second planetary gear set (P2) and to the sun gear of the fourth planetary gear set (P4) by means of a third clutch (57). The sixth shaft (6) is connected to the planet carrier of the second planetary gear set (P2) and to the ring gear of the third planetary gear set (P3), the output shaft (2) is connected to the ring gear of the fourth planetary gear set (P4) and the closing of a fourth, fifth or sixth clutch (45, 46, 56), which are also provided, can block the second planetary gear set (P2).
