Abstract
A planetary gearbox, for an automatic transmission of a motor vehicle, comprising two stages, each provided with a sun gear, a ring gear and interposed planetary gears. The ring gear of the first planetary stage also forms the sun gear of the second stage, and the planetary gears of both stages are guided by a common planet carrier, produced from a casting material, which accommodates the planetary gears of the first stage at an axial offset position to the planetary gears of the second stage. The planet carrier is designed as one-piece such that pockets are respectively disposed in the planet carrier for receiving the planetary gears of the first stage at an offset angle, in the circumferential direction, to the pockets for receiving the planetary gears of the second stage, so that it is possible to form the pockets during casting using slides.
