摘要：
A device (2) for a vehicle drivetrain (1) with a transmission unit (3) for changing various transmission ratios. The device (2) comprising a reversing gear system (4) arranged on an input side of the transmission for reversing the rotational direction. A hydrodynamic torque converter device (5) located upstream of the reversing gear system (4). A hydraulic device (6) which, in the power flow direction is located between the reversing gear system (4) and the transmission unit (3) and can be brought into active connection with them for producing a torque that can be applied in the area between the reversing gear system (4) and the transmission unit (3).
