<p>A gearbox for a motor vehicle comprises coaxially arranged solid and hollow input shafts (3, 9), each of which carries a plurality of drive gearwheels (11, 20, 28; 16, 22). Each of these drive gearwheels (11, 20, 28; 16, 22) meshes with at least one associated driven gearwheel (12, 21, 25, 29; 23, 27, 17) on one of two layshafts (4, 5), and each driven gearwheel (12, 21, 25, 29; 23, 27, 17) and its associated drive gearwheel (11, 20; 16, 22) form a gear set (11, 12; 16, 17; 20, 21; 22, 23; 20, 25; 22, 27; 28, 29) associated to a specific gear. The gear sets (11, 12; 16, 17) associated to the two lowermost gears comprise at least one shaft-end gearwheel (12, 16, 17) which has no other gearwheel between it and a bearing (7) of the shaft (3, 4, 5) carrying said shaft-end gearwheel (12, 16, 17).</p> |
