  • Patent number: 7361111
    Abstract: A power branching transmission suitable for motor vehicles having an internal-combustion engine which drives an input shaft of the power branching transmission has several branches comprising at least one power shift transmission with a number of gears and has an output shaft. For the comprehensive optimization of the power branching transmission, at least one of the branches is equipped with a control device by means of which, during the starting operation of the motor vehicle, the rotating direction of the output shaft can be changed, and during the starting operation and with shifted gears of the power shift transmission connected with the input shaft, by way of the control device, the rotational speed of the output shaft can be continuously influenced.
