Abstract
A transmission apparatus (3) outputs drive power of a motor, from a speed changing mechanism (5, 7), via a sub-shaft (25), a power distribution apparatus (4) transmits rotation of an input end member (67) linked to the sub-shaft (25), via output shafts (83, 85), to the front-wheel end and the rear-wheel end, and the sub-shaft (25) and the power distribution apparatus (4) are disposed in an axially overlapping relationship.
Claims18
A power transmission apparatus comprising:
- a transmission apparatus for outputting drive power of a motor from an input shaft, via a transmission mechanism disposed coaxially therewith, to a sub-shaft disposed in parallel thereto;
- and
- a power distribution apparatus disposed in parallel to the sub-shaft, for transmitting rotation of an input end member linked to an end of the sub-shaft, via respective output shafts, to a front-wheel and a rear-wheel end, wherein
- at least the sub-shaft and the input end member are disposed in an axially overlapping relationship,
- wherein the respective output shafts at the front wheel end and the rear wheel end of the power distribution apparatus are linked to power takeout shafts disposed in parallel thereto, respectively, and drive power is transmitted via the power takeout shafts to the front-wheel end and the rear-wheel end.
