Abstract
A motor vehicle transmission having two intermediate shafts, which can alternately be driven via disengageable primary gearwheels, and drive a main shaft, via gearwheels on the respective main shaft and intermediate shaft, which gearwheels engage with one another in pairs. Mounted on an input shaft are two lockable and disconnectable drive gearwheels, one of which directly drives the primary gearwheels in a first rotational direction, whilst the other of which, via an intermediate gearwheel, drives the primary gearwheels in an opposite direction. The realization produces a transmission having an equal number of forward and reverse gears, which can be shifted without interruption of torque.
