Parallel axis multi-stage vehicle gearbox has different diameter final drive gear wheels on first or second drive shafts to transfer torque from first and second output shafts to final reduction gear

摘要

The device has two drive shafts for torque transfer via two coaxial clutches, two output shafts parallel to the drive shafts and connected to them by several gear wheel pairs and a final reduction gear for changing the revolution rate ratio by selecting one of the gear wheel pairs. Two final drive gear wheels of different diameters on the first or second drive shafts transfer torque from the two output shafts to the final reduction gear. The device has first and second drive shafts (14,16) for torque transfer via first and second coaxial clutches (C1,C2), first and second output shafts (18,20) parallel to the drive shafts and connected to them by several gear wheel pairs and a final reduction gear (22) for changing the revolution rate ratio by selecting one of the gear wheel pairs. First and second final drive gear wheels (54,56) of different diameters on the first or second drive shafts transfer torque from the first and second output shafts to the final reduction gear.
