The transmission comprises: a gearbox having two input shafts (11, 111), that is, an inner input shaft (11) and an outer input shaft (111), respectively; a clutch unit (12) having two clutches (13, 113) operable to connect the crankshaft (14) for rotation each a respective input shaft (11, 111), wherein each clutch (13, 113) includes a driven portion (48, 50, 148, 150) connected for rotation with the respective input shaft (11, 111) and a driving portion (41, 52, 54 141, 152, 154) connected for rotation with the crankshaft (14); and a bearing (44) which supports for rotation the driving portions (41, 52, 54, 141, 152, 154) of the clutches (13, 113) on the outer input shaft (111) and which is able to withstand axial loads, the bearing (44) having an inner race which is mounted on the outer input shaft (111) and an outer race which is axially locked or restrained with respect to the driving portions (41, 52, 54, 141, 152, 154) of the clutches (13, 113). The inner race of the bearing (44) is axially locked or restrained with respect to the outer input shaft (111) in such a manner that the axial forces resulting from actuation of the clutches (13, 113) are transmitted through the bearing (44) to that shaft (111). |
