Claim:
A transmission device of a power train for distributing drive torque between first and second output shafts ( 7 , 8 ), the transmission device comprising: a first planetary gearset ( 2 ), a second planetary gearset ( 3 ), a third planetary gearset ( 11 ), and a respective first element ( 4 , 5 ) of the first and the second planetary gearsets ( 2 , 3 ) being connected to a drive input shaft ( 6 ), wherein the first and the second output shafts ( 7 , 8 ) being respectively connected to a second element ( 9 , 10 ) of the first and the second planetary gearsets ( 2 , 3 ) to form the first and the second output shafts of the transmission device ( 1 ), a third element ( 13 ) of the first planetary gearset ( 2 ) is connected, on one hand, to a first element ( 12 ) of the third planetary gearset ( 11 ) and is connectable, on the other hand, to a housing ( 15 ) of the transmission device ( 1 ) by a first brake ( 14 ), a third element ( 16 ) of the second planetary gearset ( 3 ) is connectable, on one hand, by a second brake ( 17 ) to the housing ( 15 ) and, on the other hand, is connectable by a first claw shifting element ( 18 ) to a second element ( 19 ) of the third planetary gearset ( 11 ), a third element ( 20 ) of the third planetary gearset ( 11 ) is coupled by a shaft ( 21 ) to the housing ( 15 ), a second claw shifting element ( 24 ) is connected upstream from an inner disk carrier ( 22 ) of the first brake ( 14 ) made as a disk brake, and second claw shifting element ( 24 ) is disengaged when the first brake ( 14 ) is disengaged, a third claw shifting element ( 25 ) is connected upstream from an inner disk carrier ( 23 ) of the second brake ( 17 ) made as a disk brake, and the third claw shifting element ( 25 ) is disengaged when the second brake ( 17 ) is disengaged, when the first brake ( 14 ) is to be actuated, the inner disk carrier ( 22 ) of the first brake ( 14 ) is first releasably connected to a torque-transmitting shaft connected to the third element ( 13 ) of the first planetary gearset ( 2 ) by actuating the second claw shifting element ( 24 ), located upstream from the inner disk carrier ( 22 , 23 ) of the first brake ( 14 ), and then the first brake ( 14 ) is engaged, when the second brake ( 17 ) is to be actuated, the inner disk carrier ( 23 ) of the second brake ( 17 ) is first releasably connected to a torque-transmitting shaft connected to the third element ( 16 ) of the second planetary gearset ( 3 ) by actuating the third claw shifting element ( 25 ), located upstream from the inner disk carrier ( 23 ) of the second brake ( 17 ), and then the second brake ( 17 ) is engaged, and a first actuator ( 26 ) being provided for actuating the second brake ( 17 ), the third claw shifting element ( 25 ) upstream from the inner disk carrier ( 23 ) of the second brake ( 17 ) and the first claw shifting element ( 18 ).
