Robotized gearbox for drive train of motor vehicle, has reverse pinion engaging with gear reduction pinion axially located opposite to drive pinion, and another reverse pinion with number of teeth less than that of former reverse pinion

摘要

The gearbox has a main shaft (4) connected to a crankshaft by a clutch device (3). A secondary shaft (7) has a drive pinion (8) engaging with a ring gear (9) and an intermediary shaft (114) non-coaxial with the shafts (4, 7). The shaft (114) has an intermediary reverse pinion (116) engaging with a gear reduction pinion (111) of the main shaft axially located opposite to the drive pinion. The shaft (114) has another intermediary reverse pinion (115) with number of teeth less than that of the pinion (116) and engaging with a reverse idle pinion (45) of the shaft (7).
