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.

A transmission apparatus, comprising:
- a differential planetary gear unit;
- a fluid coupling having a scoop tube disposed either at a power input side thereof or at a power output side thereof;
- and
- a converging unit;
- wherein an input rotational power input to said transmission apparatus is transmitted to said differential planetary gear unit via a single input shaft and is transmitted to a first output shaft and a second output shaft of said differential planetary gear unit;
- wherein said first output shaft of said differential planetary gear unit is connected to a first input shaft of a converging unit;
- and
- wherein said second output shaft of said differential planetary gear unit is connected to a second input shaft of said converging unit via said fluid coupling,
- wherein a first output rotational power output to said first output shaft is larger than a second output rotational power output to said second output shaft and transmitted via said fluid coupling, and
- wherein the second output rotational power output to said second output shaft is smaller than the input rotational power input to said transmission apparatus.
A transmission apparatus, comprising:
- a dividing unit to which an input rotational power from a drive unit is transmitted, said drive unit outputting a first output rotational power and a second output rotational power;
- a joint unit;
- and
- a first differential planetary gear unit receiving said first output rotational power and said second output rotational power;
- wherein said second output rotational power, which is transmitted via said joint unit, is smaller than said first output rotational power, and
- wherein said joint unit comprises an electric motor and a second differential planetary gear unit.
A transmission apparatus, comprising:
- at least one of a dividing unit and a first differential planetary gear unit;
- and
- a joint unit;
- wherein an input rotational power from a drive unit is divided into at least a first output rotational power and a second output rotational power by said dividing unit or said first differential planetary gear unit,
- wherein said second output rotational power is input to said joint unit,
- wherein said second output rotational power is smaller than the first output rotational power, and
- wherein said joint unit comprises an electric motor and a second differential planetary gear unit.
