Abstract

A planetary gearset (9) has a planetary carrier (11) and a plurality of planetary gearwheel axles arranged axially offset relative to one another and on which planetary gearwheels (13) are mounted to rotate. A first carrier section (14) is arranged at a first axial end of the planetary gearwheel axles and a second carrier section (15) is arranged at a second axial end of the planetary gearwheel axles. The first carrier section (14) is in the form of a casting with the planetary gearwheel axles formed as axially projecting journals (17) made integrally with the first carrier section (14). The second carrier section (15) is attached as a separate component onto the journals (17), and the first carrier section (14) and the second carrier section (15) hold the journals (17) axially at both ends at fixed, unvarying axial distances apart from one another.
