Patent ID: 7156768

Claim:
A multi-stage transmission of planetary structure for a motor vehicle which comprises a drive input shaft and a drive output shaft arranged in a housing, three single-web planetary gearset assemblies (P 2 , P 2 , P 3 ), at least six rotating shafts ( 0 , 1 , 2 , 3 , 4 , 5 , 6 ) and at least five shift elements ( 03 , 04 , 13 , 16 , 45 ) which comprise one of brakes and clutches, whose selective engagement, two at a time, produce various transmission ratios between the drive input and the drive output shafts so that six forward gears and one reverse gear can be engaged; wherein the drive input shaft ( 1 ) is connected directly to a sun gearwheel of a first planetary gearset assembly (P 1 ), an annular gearwheel of the first planetary gearset assembly (P 1 ) is connected with the housing, a drive output takes place via a second shaft ( 2 ) which is connected to an annular gearwheel of a second planetary gearset assembly (P 2 ) and to a web of a third planetary gearset assembly (P 3 ), a third shaft ( 3 ) is permanently connected to a web of the second planetary gearset assembly (P 2 ) and to an annular gearwheel of the third planetary gearset assembly (P 3 ), a fourth shaft ( 4 ) is permanently connected to a sun gearwheel of the second planetary gearset assembly (P 2 ), a fifth shaft ( 5 ) is permanently connected to a web of the first planetary gearset assembly (P 1 ), and a sixth shaft ( 6 ) is permanently connected to a sun gearwheel of the third planetary gearset assembly (P 3 ), such that the third shaft ( 3 ) can be coupled to the housing by a first brake ( 03 ), the fourth shaft ( 4 ) can be coupled to the housing by a second brake ( 04 ), a first clutch ( 13 ) facilitates connection and disconnection of the drive input shaft ( 1 ) and the third shaft ( 3 ) with one another, a second clutch ( 16 ) facilitates connection and disconnection of the drive input shaft ( 1 ) and sixth shaft ( 6 ) with one another, and a third clutch ( 45 ) facilitates connection and disconnection of the fourth and the fifth shafts ( 4 , 5 ) with one another and the first and second brakes ( 03 , 04 ) and the first, the second and the third clutches ( 13 , 16 , 45 ) are all located between the first and the second planetary gearset assemblies (P 1 , P 2 ).
