Zusammenfassung:Gearbox with a dual input clutch, comprising two concentric primary shafts (1, 10) respectively connected to the first clutch (E1) and to the second clutch (E2), fixed pinions (2, 3, 4, 11, 12) distributed between the two primary shafts, two secondary shafts (20, 30) bearing idling pinions (21, 22, 23, 24, 31, 32) meshing with the fixed pinions of the primary shafts and means (M1, M2, M3, M4) for coupling the idling pinions, characterized in that the first forward-gear ratio and the reverse-gear ratio are established by combining the use of the idling pinion (24) for the second forward-gear ratio and the bridging of the two primary shafts (1, 10) via two intermediate-gear-ratio idling pinions of adjacent rows (22, 23) rotating about the same secondary shaft (20) as the second-gear idling pinion (24).
