Patent ID: 7654927

Claim:
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.
