<p>A gearbox for a motor vehicle comprises coaxial first and second input shafts (3, 4) carrying a plurality of gearwheels (11, 13, 20, 23, 29), and first to third layshafts (5, 6, 7) selectively drivable by said input shafts (3, 4). Each gearwheel (11, 13, 20, 23, 29) of said input shafts (3, 4) meshes with at least one gearwheel (12, 14, 21, 22, 24, 25, 28) of said first or second layshafts (6, 7). The three layshafts (5, 6, 7) carry first to third pinions (8, 9, 10) meshing with a same output gearwheel, and the third layshaft (5) further carries a reverse gearwheel (16) meshing with a gearwheel (15) of said first layshaft (6).</p> |
