DOUBLE GEARBOX, AND METHOD FOR ENGAGING AN OVERALL GEAR RATIO THEREIN

摘要

A double gearbox comprises a first and a second input shaft; a countershaft; an output shaft; a first component gearbox with two gearwheel sets, of which one can be connected selectively in a torque-locking manner between the first input shaft and the countershaft; a second component gearbox with two gearwheel sets, of which one can be connected selectively in a torque-locking manner between the second input shaft and the countershaft; and a third component gearbox with a gearwheel set which can be connected in a torque-locking manner between the countershaft and the output shaft. Here, one of the gearwheel sets of the first component gearbox coincides with one of the gearwheel sets of the second component gearbox.
