<p>A hybrid vehicle drive system includes an internal combustion engine 1, a transfer gearbox 20 which divides the output of a gearbox 3 (a CVT) between front and rear axles and an electric motor 31 and arrangement of clutches 29, 30 and 32 between the parts of a two-part propeller shaft 26, 27 in the drive to one axle. Selective operation of one or more of the clutches gives four-wheel drive or two-wheel drive using either or both of the internal combustion engine and electric motor. The motor 31 may be connected to the propeller shafts through the clutch 32 and gearing 28 or may be in line with the two parts of shaft with the clutch 32 and gearing 28 omitted.</p> |
