Abstract (en)
[origin: WO2013160000A1] The invention relates to a multi-speed gearbox comprising 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, 05, 14, 17, 8), wherein the sun gear of the first planetary gear set (P1) is connected to the fifth shaft (5), which can be coupled to the housing (G) via a third brake (05). The drive shaft (1) can be detachably connected to the fourth shaft (4) via a first clutch (14), which connects to the web of the first planetary gear set (P1), to the ring gear of the first planetary gear set (P1), to the planet carrier of the second planetary gear set (P2) and can be coupled to the housing (G) via a second brake (04). The drive shaft (1) can be connected to the seventh shaft (7) which is connected to the planet carrier of the fourth planetary gear set (P4) and to the ring gear of the third planetary gear set (P3) by means of a second clutch (17), and can be connected to the eighth shaft (8) which is connected to the sun gear of the second planetary gear set (P2) by means of a third clutch (18). The sixth shaft (6) is connected to the planet carrier of the first planetary gear set (P1),to the ring gear of the second planetary gear set (P2) and to the ring gear of the fourth planetary gear set (P4), the third shaft (3) is connected to sun gear of the third planetary gear set (P3) and to the sun gear of the fourth planetary gear set (P4) and can be coupled to the housing (G) by means of a first brake (03). The output shaft (3) of the gearbox is connected to the planet carrier of the third planetary gear set (P3).
