Patent ID: 7507178

Claim:
A transmission unit ( 7 ) comprising: a housing ( 9 ), a transmission input shaft ( 10 ), first, second and third transmission output shafts ( 11 , 12 , 13 ), at least first and second planetary gearsets ( 14 , 15 ) with each comprising a solar sear, an annular gear, and a web ( 14 D, 15 D) supporting a plurality of planet gears which mesh with the solar gear and the annular gear, a device ( 16 ) being arranged between first and second actively interconnected shafts ( 14 A, 15 A) of at least the first and the second planetary gearsets ( 14 , 15 ) for variable distribution of torque delivered by the transmission input shaft ( 10 ) between the first, the second and the third transmission output shafts ( 11 , 12 , 13 ), the web ( 14 D) of the first planetary gearset ( 14 ) being connected to a differential cage ( 19 A) of a differential ( 19 ) which is provided to distribute a portion of the torque which is delivered by the transmission input shaft ( 10 ) to the first and the second transmission output shafts ( 11 , 12 ), and the differential ( 19 ) being located between the first and the second transmission output shafts ( 11 and 12 ).
