Beschreibung
Zusammenfassung:	A powertrain for a hybrid vehicle includes an engine, a transmission and an electric machine disposed therebetween. The electric machine includes a stator housing, a stator mounted within the stator housing and a rotor mounted radially within and coaxial with the stator. The electric machine further includes a first clutch disposed between the engine and the rotor, and a second clutch disposed between the rotor and the transmission. The first and second clutches include non-ferrous clutch plates which are adapted to be immersed in hydraulic fluid. The electric machine has a first mode wherein the electric machine provides torque to the engine, a second mode wherein the electric machine is driven by the engine and a third mode wherein the electric machine provides torque to the transmission. The first and second clutches are positioned radially within the stator housing and axially within the length of the stator housing.
