Abstract (en)

[origin: WO2020083723A1] The invention relates to a multi-speed transmission (10) which is driven via an electric machine (64). The multi-speed transmission (10) has a planet carrier (22), on which at least one first and second stepped planetary gear (24, 30) are received. First planetary steps (26, 32) of the stepped planetary gears (24, 30) mesh with a first sun gear (18), and second planetary steps (28, 34) of the stepped planetary gears (24, 30) mesh with a second sun gear (20, 54). A first brake (38) is paired with the first sun gear (18), and a second brake (42) is paired with the second sun gear (20, 54), the actuation of each said brake producing a first gear ratio, a second gear ratio for a parking lock function, and an overlapping gear shift.
