Patent ID: 8613687

Claim:
A planetary gearbox for an automatic transmission of a motor vehicle, the planetary gearbox comprising: first and second stages ( 1 , 2 ), each stage being provided with a sun gear ( 3 ), a ring gear ( 5 , 9 ) and interposed planetary gears ( 4 A- 4 C, 8 A- 8 C), the ring gear ( 5 ) of the first planetary stage ( 1 ) also forming the sun gear of the second stage ( 2 ), the planetary gears ( 4 A- 4 C, 8 A- 8 C) of both of the first and the second stages ( 1 , 2 ) being guided by a common planet carrier ( 10 ; 10 ′), produced from a casting material, which accommodates the planetary gears ( 4 A- 4 C) of the first stage ( 1 ) at an axial offset (x S ) with respect to the planetary gears ( 8 A- 8 C) of the second stage ( 2 ), the planet carrier ( 10 ; 10 ′) being designed as one-piece such that pockets ( 11 A- 11 C; 11 A′- 11 D′) are respectively disposed in the planet carrier ( 10 ; 10 ′) for receiving the planetary gears ( 4 A- 4 C) of the first stage ( 1 ) at an offset angle (α Versatz ; α Versatz1,2 ) in a circumferential direction to pockets ( 12 A- 12 C; 12 A′- 12 C′) for receiving the planetary gears ( 8 A- 8 C) of the second stage ( 2 ) so that the pockets being formed during casting using slides.
