<p>A double clutch manual transmission comprises a drive shaft 1, a first main shaft 2, a first friction clutch 8, a second main shaft 3, a second friction clutch 9 and a plurality of gear sets comprising gears 4, 5, 22, 6, 7, 23 on one of the main shafts 2, 3 which mesh with gears 33, 29, 27, 34, 30, 28 on at least one first auxiliary shaft 25. At least two of the gear sets 4, 33; 6, 34 comprise idler gears 33, 34, meshing with fixed gears 4, 6, are coupled by a double-acting first selector sleeve 31 to the auxiliary shaft 25. At least one gear set 22, 27 comprises an idler gear 22 which is coupled by a second selector sleeve 10 to the main shaft 2, and meshes with a fixed gear 27 on one of the auxiliary shafts 25. The selector sleeves are operated by a sequencing mechanism comprising first and second rotation-translation mechanisms 71, 72 having a pin and cam devices 46 or coulisses which are driven by electric motors.</p> |
