Patent ID: 7097583

Claim:
A power-branched transmission with a steplessly adjustable transmission ratio, comprising: an input side distributor transmission with an input gear nonrotatably connected with an input shaft, a variable speed drive unit including an input shaft and an output shaft that is radially spaced from and parallel to the input shaft, wherein each of the input and output shafts of the variable speed drive unit is operatively connected with the distributor transmission, an output shaft of the power-branched transmission, and at least two clutches positioned between a power-branched transmission output shaft and the distributor transmission input shaft, whereby the input gear of the distributor transmission is in rotational engagement with the input shaft of the variable speed drive unit through at least one gear of the distributor transmission, an output gear of the distributor transmission is rotatably coupled with an intermediate shaft arranged functionally in parallel to the input and output shafts of the variable speed drive unit, wherein the intermediate shaft is also rotatably coupled with the output shaft of the variable speed drive unit, the intermediate shaft is rotatably coupled with the output shaft of the power-branched transmission through a first clutch, and the input shaft of the variable speed drive unit is rotatably coupled with the output shaft of the power-branched transmission through a second clutch.
