The gear box has a double clutching device (100) rotatively connecting idle pinions (81, 82) with a secondary shaft (50) to obtain first and reverse ratios, respectively. An auto assisted conic coupler (101) rotatively connects idle pinions (83, 84) with the shaft (50) to obtain sixth and fourth ratios, respectively. An auto assisted conic coupler (102) rotatively connects idle pinions (93, 94) with the shaft (60) to obtain fifth and third ratios, respectively. An auto assisted conic coupler (103) rotatively connects an idle pinion (25) with a main shaft (20) for obtaining a second ratio. |
