Patent ID: 6958031

Claim:
An automatically shiftable motor vehicle transmission of planetary design for a motor vehicle, comprising: an input drive shaft ( 1 ) and an output drive shaft ( 2 ) that are arranged in a housing (G); first, second and third single-carrier planetary gear sets (P 1 , P 2 , P 3 ); third, fourth, fifth and sixth rotatable shafts ( 3 , 4 , 5 , 6 ); a plurality of shifting elements comprising first, second and third brakes ( 03 , 04 , 05 ), and first, second, and third clutches ( 14 , 15 , 45 ) selective engagement of which brings about various conversion ratios between the input drive shaft ( 1 ) and output drive shaft ( 2 ), so that at least seven forward speeds can be implemented; the input drive shaft ( 1 ) being continuously connected to a sun gear of the second planetary gear set (P 2 ) and being connectable via the first clutch ( 14 ) to a carrier of the first planetary gear set (P 1 ) and being connectable via the second clutch ( 15 ) to the fifth shaft ( 5 ) which is continuously connected to a sun gear of the first planetary gear set (P 1 ) and is couplable via the third brake ( 05 ) to the housing (G); the output drive shaft ( 2 ) being continuously connected to a carrier of the third planetary gear set (P 3 ) and to the ring gear of the first planetary gear set (P 1 ); the third shaft ( 3 ) being continuously connected to a sun gear of the third planetary gear set (P 3 ) and being couplable by way of the first brake ( 03 ) to the housing (G); the fourth shaft ( 4 ) being continuously connected to a ring gear of the second planetary gear set (P 2 ) and to the carrier of the first planetary gear set (P 1 ), and being directly couplable to the housing (G) through only the second brake ( 04 ); the sixth shaft ( 6 ) being continuously connected to a ring gear of the third planetary gear set (P 3 ) and to a carrier of the second planetary gear set (P 2 ); and the third clutch ( 45 ) being provided which releasably connects the fourth shaft ( 4 ) to one of the fifth shaft ( 5 ) and the output drive shaft ( 2 ).
