<p>The invention concerns a gearbox wherein the clutch shaft ( 3 ) selectively drives one or the other of two input shafts ( 1,2 ) by means of two clutches ( 8 ). The pinion torques defining the successive ratios are configured such that the power is alternately transmitted by one clutch ( 8 ) and by the other when the transmission ratios are made to succeed each other sequentially upon use of the gearbox. The input shafts ( 1,2 ) are non-coaxial and bear input pinions (E 3 , E 4 , E 5 , E 6 ) which mesh with the same output pinions (S 234 , S 56 R). In an improved embodiment, one ( 1 ) of the input shafts drives an intermediate shaft ( 15 ) which in turn likewise drives the same output pinions (S 234 , S 56 R) via the input pinions (E 4 , E 6 ) borne by said input shaft and operating this time as freely rotating motion transmitter pinions. The invention provides a compact device, and minimization of the number of pinions.</p> |
