    Patent number: 6595077
    Abstract: A change-speed gearbox has an input shaft connected to an output shaft by at least one first and one second component transmission, arranged parallel to one another in the power flow and each having a frictional power-shift clutch and an intermediate shaft. The intermediate shaft can be operatively connected to the input shaft by the power-shift clutch, with at least one gearbox constant per component transmission. Each gearbox constant has a gearwheel on one of the two intermediate shafts, at least one of which can be operatively connected to a first layshaft arranged parallel to the input shaft. At least one gearbox constant can be brought into an operative connection with the first and the second power-shift clutch.
