Abstract

The invention relates to a motor vehicle gearbox with two concentrically mounted input shafts (6,9), each driving an individual countershaft (12,15). The countershafts have gear wheels (16,18,19,41) in engagement with gear wheels (21,22,40) on an output shaft. The shafts are arranged in a V-configuration and one countershaft has a disengageable gear wheel (23) in engagement with a gear wheel (11) on the second countershaft to reverse the rotational direction of the latter for driving in reverse. One countershaft (12) has a central synchronizing device (30), by means of which the countershaft, which is drivingly coupled to the temporarily non-driven input shaft, can be accelerated up to a rotational speed determined by the gear speed selected.
