Abstract

A transmission for a power train of a vehicle includes an input shaft, two output shafts, and a differential arranged between the two output shafts. The differential includes two planetary gear sets, which include multiple gear set elements. A first output torque is at least indirectly transmittable onto the first output shaft by the first planetary gear set. A support torque of the first planetary gear set is convertible in the second planetary gear set such that a second output torque, which corresponds to the first output torque, is transmittable onto the second output shaft. A second gear set element of the first planetary gear set is connected to the first output shaft for conjoint rotation via a spline. At least one first duct for axial passage of lubricant is formed between inner toothing and the outer toothing of the spline.
