Abstract

A power-branched transmission having a steplessly adjustable transmission ratio. An input-side distributor transmission includes an input gear that is nonrotatably connected with an input shaft coupled to an engine. The power-branched transmission includes an output shaft and two clutches. The input gear of the distributor transmission is rotatably coupled with an input shaft of a variable speed drive unit. An output gear of the distributor transmission is rotatably engaged with an intermediate shaft that is arranged in a functionally parallel manner relative to the variable speed drive unit and is rotatably engaged with an output shaft of the variable speed drive unit. The intermediate shaft is operatively coupled with the output shaft through a first clutch and the input shaft of the variable speed drive unit is operatively coupled with the output shaft through a second clutch.
