Abstract

A transmission (1) for an electric drive of a vehicle includes a first input shaft (10), a second input shaft (11), an output shaft (12), two shift elements (3, 4) for connecting the transmission (1) to an electric machine of the electric drive, and a planetary gear set (5) configured as a stepped planetary gear set. A first sun gear (5.1) of the planetary gear set (5) is rotationally fixed to the first input shaft (10). A second sun gear (5.2) of the planetary gear set (5) is rotationally fixed to the second input shaft (11). A ring gear (5.5) of the planetary gear set (5) is fixed at a rotationally fixed component (0) of the transmission (1). A planet carrier (5.6) of the planetary gear set (5) is rotationally fixed to the output shaft (12). A first shift element (3) is configured for connecting the first input shaft (10) to the electric machine of the electric drive. A second shift element (4) is configured for connecting the second input shaft (11) to the electric machine of the electric drive.
