1. A planetary gearset comprising:
a planetary carrier with a plurality of planetary gearwheel axles arranged axially offset relative to one another;
a planetary gearwheels rotatably mounted on each of the plurality of planetary gearwheel axles;
a first carrier section is arranged on a first axial side of the planetary gearwheel, the first carrier section is in a form of a casting, wherein each of the planetary gearwheel axles is made integrally with the first carrier section in a form of axially projecting journals, wherein the first carrier section has a cup shape with a radially extending bottom section connected as one piece with a first end of a hollow cylindrical wall that extends axially therefrom, and wherein the journals project axially from the radially extending bottom section of the first carrier section in a same direction as the hollow cylindrical wall and are located radially inside of the hollow cylindrical wall;
a second carrier section is attached as a separate component to smooth end faces of the journals; and
the first carrier section and the second carrier section hold the journals at both ends at fixed, unvarying axial distances from one another.
