Abstract
A vehicle powertrain includes first and second power sources and a transmission assembly having first and second input members and an output member. The transmission assembly also includes a first planetary gear-set connected to the first input member and a second planetary gear-set connected to the second input and the output members. The transmission assembly additionally includes a transmission housing retaining the first and second gear-sets. Furthermore, the transmission assembly includes a first torque-transmitting device for connecting one first gear-set node to the housing and a second torque-transmitting device for connecting a first gear-set node not connected to the housing to one second gear-set node. One first gear-set node is directly and continuously connected to one second gear-set node. The first power source is operatively connected to a node of the first gear-set and the second power source is operatively connected to a node of the second gear-set.
