Patent ID: 8206258

Claim:
A gearset arrangement of a planetary transmission, the gearset arrangement comprising: at least a simple radially inner planetary gearset ( 1 ) and a simple radially outer planetary gearset ( 11 ) each comprising a sun gear ( 2 , 12 ′), a ring gear ( 3 ′) and a carrier ( 5 ) that carries a plurality of planetary gears ( 4 , 14 ); the radially inner and radially outer planetary gearsets ( 1 , 11 ) being coaxially arranged such that the radially inner planetary gearset ( 1 ) being radially nested inside the sun gear ( 12 ) of the radially outer planetary gearset ( 11 ) in one of a common radial plane and adjacent radial planes ( 6 , 16 ) being axially offset with respect to one another; the ring gear ( 3 ) of the radially inner planetary gearset ( 1 ) and the sun gear ( 12 ) of the radially outer planetary gearset ( 11 ) being at least coupled to one another in a rotationally fixed manner and being connected by gearing teeth ( 34 ) to a common carrier ( 25 ′), the ring gear ( 3 ′) of the radially inner planetary gearset ( 1 ) and the sun gear ( 12 ′) of the radially outer planetary gearset ( 11 ) being separate components having different heat treatments and being connected together and, via the gearing teeth ( 34 ), to the common carrier ( 25 ′) in a rotationally fixed manner on a carrier side in an area of an outer cylindrical section ( 31 ) of the ring gear ( 3 ′) of the radially inner planetary gearset ( 1 ) and an inner cylindrical section ( 32 ) of the sun gear ( 12 ′) of the radially simple planetary gearset ( 11 ); the ring gear ( 3 ′) and the sun gear ( 12 ′) being arranged with at least a partial axial overlap relative to one another, and adjacent to an axially outer edge ( 33 ) of the at least partial axial overlap, distributed around the periphery, radially through-going carrier openings ( 35 ), being axially open on one side, are arranged on the ring gear ( 3 ′) and carrier openings ( 36 ), radially closed on an outside and axially open on one side, being arranged on the sun gear ( 12 ′) in which corresponding radial gearing teeth ( 37 ) of the carrier ( 25 ′) engage in an assembled condition.
