Transmission for an Electric Drive or Drive Train of a Vehicle, Electric Drive and Drive Train

An electric drive for a vehicle, comprising:

• an electric machine (2);
• a transmission (1) comprising a first input shaft (10), a second input shaft (11), an output shaft (12), at least two shift elements (3, 4, 6, 7) for selectively connecting the transmission (1) to the electric machine (2), and a planetary gear set (5) configured as a stepped planetary gear set with planetary gears (5.3, 5.4) mounted at a planet carrier (5.6), the planetary gears (5.3, 5.4) having two different sized effective diameters,
• wherein a first sun gear (5.1) of the planetary gear set (5) is meshed with a larger effective diameter (5.3) of the planetary gears,
• wherein a second sun gear (5.2) of the planetary gear set (5) is meshed with a smaller effective diameter (5.4) of the planetary gears,
• wherein a ring gear (5.5) of the planetary gear set (5) is meshed with the larger effective diameter (5.3) of the planetary gears,
• wherein a first sun gear (5.1) of the planetary gear set (5) is rotationally fixed to the first input shaft (10),
• wherein a second sun gear (5.2) of the planetary gear set (5) is rotationally fixed to the second input shaft (11),
• wherein a ring gear (5.5) of the planetary gear set (5) is fixed at a rotationally fixed component (0) of the transmission (1),
• wherein the planet carrier (5.6) of the planetary gear set (5) is rotationally fixed to the output shaft (12),
• wherein a first shift element (3) of the at least two shift elements (3, 4, 6, 7) is configured for selectively connecting the first input shaft (10) to the electric machine of the electric drive, and
• wherein a second shift element (4) of the at least two shift elements (3, 4, 6, 7) is configured for selectively connecting the second input shaft (11) to the electric machine (2) of the electric drive.
