ABSTRACT:
The invention relates to a vehicle gearbox of tye type which has two concentrically journalled input shafts connected to a double clutch for alternate engagement. The input shafts drive two intermediate shafts, which lie in a plane offset from the input shafts and having a pair of gears permanently engaged with each other, one of which is the gear for the second gear speed on one of the intermediate shafts, while the other gear is an extra gear freely rotatable and lockable to the hub of the gear for the first gear speed, on the other intermediate shaft. By releasing the gear for the first gear speed from its intermediate shaft and locking the extra gear to the gear wheel hub for the first gear speed, the rotational direction of the second intermediate shaft can be reversed for backing.
