Abstract
A powertrain includes an electric machine including a rotor defining a hollow center and a fluid-coupling assembly at least partially disposed within the hollow center. The fluid-coupling assembly includes an input shaft, a turbine fixedly coupled to the rotor and having a hub configured to connect with a transmission input shaft, and an impeller configured to fluid couple with the turbine. The impeller is selectively coupled to the rotor and selectively coupled to the input shaft.

A powertrain comprising:
- an electric machine including a rotor defining a hollow center;
- and
- a fluid-coupling assembly at least partially disposed within the hollow center, the assembly including:
- an input shaft,
- a turbine fixedly coupled to the rotor and having a huh configured to connect with a transmission input shaft, and
- an impeller configured to fluidly couple with the turbine, the impeller being selectively coupled to the rotor and selectively coupled to the input shaft.
An electric machine assembly with integrated fluid coupling, comprising:
- an electric machine including, a rotor;
- an input shaft supported for rotation within the rotor;
- a fluid-coupling including a turbine fixedly coupled to the rotor and an impeller;
- and
- a clutch assembly configured to selectively couple the impeller to the input shaft and to selectively couple the impeller to the rotor.
