1. A power train (1) for a motor vehicle (100), comprising:
an electric machine (2); and
a transmission (3) comprising at least one first planetary gear set (P1) with a plurality of gear set elements that include a sun gear (P1.1), a planet carrier (P1.2) guiding one or multiple planet gears, and a ring gear (P1.3),
wherein the electric machine (2) comprises a rotor (4) for transmitting drive power via a rotor shaft (5) at least indirectly onto a first gear set element of the first planetary gear set (P1) meshing with the one or multiple planet gears, and
wherein the rotor shaft (5) is connected via a spline (6) to the first gear set element of the first planetary gear set (P1) for conjoint rotation such that the first gear set element in the first planetary gear set (P1) is axially movable within an axial play of the first gear set element while the rotor shaft (5) substantially retains an axial position of the rotor shaft (5), the spline being different from the meshing between the first gear set element and the one or multiple planet gears.
