Abstract
The present invention relates to a transmission apparatus (15) including at least one of a dividing unit (6) and a differential planetary gear unit (30), and a joint unit (20). A rotational power, which has been input to the transmission apparatus (15), is transmitted to the joint unit (20) via the dividing unit (6) or the differential planetary gear unit (30). A rotational power to be input to the joint unit (20) is smaller than the rotational power which has been input to the transmission apparatus (15), and the joint unit comprises a fluid coupling.

- and
- a joint unit;
- wherein a rotational power to be transmitted via said joint unit is smaller than a rotational power which has been input to said transmission apparatus, said joint unit comprises a fluid coupling, said fluid coupling has a scoop tube, and said scoop tube is disposed either at a power input side or at a power output side.
A transmission apparatus comprising:
- at least one of a dividing unit and a differential planetary gear unit;
- and
- a joint unit;
- wherein a rotational power which has been input to said transmission apparatus is transmitted to said joint unit via said dividing unit or said differential planetary gear unit, the rotational power to be transmitted to said joint unit is smaller than the rotational power which has been input to said transmission apparatus, said joint unit comprises a fluid coupling, said fluid coupling has a scoop tube, and said scoop tube is disposed either at a power input side or at a power output side.
A transmission apparatus comprising:
- a dividing unit to which a rotational power from a drive unit is transmitted;
- a joint unit;
- and
- a first differential planetary gear unit;
- wherein one rotational power to be transmitted via said joint unit is smaller than the other rotational power, and said joint unit comprises an electric motor and a second differential planetary gear unit.
A transmission apparatus comprising:
