Patent ID: 8066606

Claim:
A multi-group transmission of a motor vehicle, with at least two transmission groups ( 2 , 3 ) arranged in a drivetrain and a means for supporting traction force during gearshift operations, the multi-group transmission comprising: a clutch mechanism ( 16 , 16 ′) arranged between a drive motor ( 5 ), having a driveshaft ( 6 ), and a transmission input ( 7 ), having a transmission input shaft ( 40 ), a frictional clutch ( 41 , 41 ′) and first and second shifting clutches ( 42 , 42 ′, 43 , 43 ′), the driveshaft ( 6 ) being connectable to the transmission input shaft ( 40 ) by a first shifting clutch ( 42 , 42 ′) in either a first shift position (S 1 , K 1 ) in active combination with the frictional clutch ( 41 , 41 ′), or a second shift position (S 2 , K 2 ) with bridging of the frictional clutch ( 41 , 41 ′), and the driveshaft ( 6 ) being directly connectable to a main transmission shaft ( 30 ) on a drive output side by a second shifting clutch ( 43 , 43 ′) in active combination with the frictional clutch ( 41 , 41 ).
