<p>The gearbox comprises: a first inner input shaft (10) which carries driving gearwheels (21, 23, 27) associated to the odd gears (I, III, V, VII); a second outer input shaft (12) carries driving gearwheels (22, 24) associated to the even gears (II, IV, VI) and to reverse gear (R); and first and second output shafts (14, 16) carrying idle driven gearwheels (31-38). A first driving gearwheel (21) meshes only with the driven gearwheel (31) of first gear (I); a second driving gearwheel (23) meshes both with the driven gearwheel (33, 35) of third gear (III) and of fifth gear (V); a third driving gearwheel (27) meshes only with the driven gearwheel (37) of seventh gear (VII); a fourth driving gearwheel (24) meshes both with gearwheel (34, 36) of fourth gear (IV) and of sixth gear (VI); and fifth driving gearwheel (22) meshes with the driven gearwheel (32) of second gear (II) and, via this latter, with the driven gearwheel (38) of reverse gear (R).</p> |
