Abstract (en)
[origin: WO2013159990A1] The invention relates a four-speed multi-speed gearbox in which a sun gear (41) of a fourth planetary gear set (4) is ridigly connected to the housing (72), a ring gear (13) of a first planetary gear set (1) is permanently connected to a ring gear (43) of the fourth planetary gear set (4), a sun gear (11) of the first planetary gear set (1) and a sun gear (21) of a second planetary gear set (2) can be coupled to the housing (72) by means of a first brake (51), a planet carrier (12) of the first planetary gear set (1) can be coupled to the housing (72) by means of a second brake (52) and the output shaft (71) can be coupled to the planet carrier (42) of the fourth planetary gear set (4) by means of a first clutch (61). By varying other clutches within the multi-speed gearbox, a set of gearboxes which have similar characteristics are provided.
