Abstract: A gear unit for a powertrain of a vehicle includes a stepped planetary gearset, a first gear shifting element and a second gear shifting element. The stepped planetary gearset has at least a first ring gear, a second ring gear and a plurality of stepped planet gears rotatably mounted at a first planet carrier. The first planet carrier drivingly connects to an electric machine. The second ring gear is connected to an output shaft of the gear unit so as to be fixed with respect to rotation relative to it. The first gear shifting element fixes the first ring gear relative to a housing in a closed state, and the second gear shifting element brings the stepped planetary gearset into direct drive in a closed state. One of the two gear shifting elements is in the closed state for driving the output shaft in rotation.
