A four-stage multi-stage transmission in which the carrier (12) of the first planetary gear set (1) is connected with a sun gear (41) of the fourth planetary set, a ring gear (43) of the fourth planetary gear set (4) is connected with the output shaft (71), a ring gear (13) of the first planetary gear set (1) and a carrier (22) of the second planetary gear set (2) can be coupled with the housing (72), via a first brake (51). A sun gear (11) of the first planetary gear set (1) can be coupled with the housing (72), via a second brake (52), and the ring gear (43) can be coupled with the sun gear (41), respectively, of the fourth planetary gear set (4) via a first clutch (61). |
