<p>An auxiliary-range transmission (1) for a motor vehicle is proposed which comprises at least one power-splitting stage (8) and at least one power-combining stage (6) and therebetween at least two drive trains (3, 9) disposed parallel to each other having each at least one shifting element (5, 10), there being situated in one of the drive trains (3) one continuously variable transmission (4) which can be implemented by a continuously variable adjustment of the ratio of the whole transmission (1) in a particular speed. A gear is changed here without interruption of tractive force and with a power reversal in the continuously variable transmission (4). During a range change a load transfer occurs on at least one shifting element (5, 10) of frictional type by an adjustment of ratio of the continuously variable transmission (4) simultaneous with the shifting of the shifting elements (5, 10).</p> |
