Claim Text:
1. A hybrid drive unit, comprising: a first planetary gear set connected to an input shaft and a second planetary gear set connected to the first planetary gear set by an electric machine shaft; a first electric machine connected to the first planetary gear set and a second electric machine connected to the first and second planetary gear sets by the electric machine shaft; an output shaft selectively directly coupled to the electric machine shaft by a first clutch mechanism, wherein the input shaft, electric machine shaft and output shaft are distinct shafts that share a common axis of rotation; a second clutch mechanism configured to selectively couple the first electric machine to the second planetary gear set; a drive shaft connected to the second planetary gear set by a first driven gear and to the output shaft by at least one drive gear, wherein the drive shaft is parallel to and spaced apart from the electric machine shaft; wherein the output shaft is configured to be i) selectively directly connected to the second electric machine via the electric machine shaft by activation of the first clutch mechanism and ii) indirectly coupled to the second electric machine via the second planetary gear set and the drive shaft; and wherein the drive shaft extends parallel to the electric machine shaft and external to and around the second electric machine.
