Abstract:
1. A device ( 2 ) for a vehicle drivetrain ( 1 ) with a transmission unit ( 3 ) for changing various transmission ratios, a reversing gear system ( 4 ) being arranged on a transmission input side for reversing a rotational direction, a hydrodynamic torque converter device ( 5 ) being arranged upstream of the reversing gear system ( 4 ) and with a hydraulic device ( 6 ) located in a power flow between the reversing gear system ( 4 ) and the transmission unit ( 3 ) and being actively connectable with the reversing gear system ( 4 ) and the transmission unit ( 3 ) such that a torque, which is applied in an area between the reversing gear system ( 4 ) and the transmission unit ( 3 ), is produced by the hydraulic device ( 6 ).
