1. A transmission (1) for a drive train of a vehicle (100), comprising:
an input shaft (2);
a first output shaft (3);
a second output shaft (4); and
a differential arranged in power flow between the input shaft (2) and the first and second output shafts (3, 4), the differential comprising a first planetary gear set (5) with a plurality of planet gears (5.4) and a plurality of gear set elements, the differential comprising a second planetary gear set (6) with a plurality of planet gears (6.4) and a plurality of gear set elements, a first output torque transmittable onto the first output shaft (3) by the first planetary gear set (5), a support torque of the first planetary gear set (5) convertible in the second planetary gear set (6) such that a second output torque corresponding to the first output torque is transmittable onto the second output shaft (4),
wherein a first gear set element of the gear set elements of the first planetary gear set (5) is connected to the input shaft (2) for conjoint rotation,
wherein a third gear set element of the gear set elements of the first planetary gear set (5) is connected to the first output shaft (3) for conjoint rotation,
wherein a second gear set element of the gear set elements of the second planetary gear set (6) is connected to the second output shaft (4) for conjoint rotation,
wherein a third gear set element of the gear set elements of the second planetary gear set (6) is connected to a stationary component for conjoint rotation,
wherein the second planetary gear set (6) is axially adjacent the first planetary gear set (5), and the planet gears (5.4) of the first planetary gear set (5) do not axially overlap the planet gears (6.4) of the second planetary gear set (6), and
wherein a second gear set element of the gear set elements of the first planetary gear set (5) comprises a ring gear (5.2) and is connected to a first gear set element of the gear set elements of the second planetary gear set (6) for conjoint rotation, the first gear set element of the gear set elements of the second planetary gear set (6) comprises a sun gear (6.1), and the sun gear (6.1) of the second planetary gear set (6) is arranged on an end face of the ring gear (5.2) of the first planetary gear set (5) and axially fixed by a securing ring (17).
