Abstract
A hybrid powertrain includes a torque converter including an impeller, a turbine, and a stator, wherein the impeller is configured to receive torque from the engine input shaft without utilizing a torque converter cover or shell. The hybrid powertrain includes an electric machine including a rotor and motor stator, wherein the electrical machine is configured to transfer torque to a transmission input via the rotor.
Claims20
A torque converter comprising:
- an impeller;
- a turbine adjacent the impeller and configured to fluidly couple with the impeller, wherein the turbine and the impeller are supported for rotation about an axial centerline of the torque converter, wherein the turbine includes a turbine shell connected to a transmission input shaft and configured to transfer torque to the transmission input shaft, wherein the turbine is further connected to an electrical machine that includes a rotor and a motor stator, wherein the turbine shell is non-rotatably connected to the rotor via a fixed connection;
- a stator adjacent both the turbine and the impeller, wherein the stator is connected to a secondary housing via a stator shaft;
- and
- a disconnect clutch assembly connected to an engine and the impeller via an impeller shaft, wherein the disconnect clutch assembly is configured to transfer torque from the engine to the impeller via the impeller shaft.

(canceled)
A hybrid powertrain comprising:
- a torque converter including an impeller, a turbine, a turbine shell, a stator, and a clutch assembly connected to an engine and the impeller, wherein the clutch assembly is configured to transfer torque from the engine to the impeller before torque transfers to the turbine without transferring torque to a torque converter cover;
- and
- an electric machine including a rotor and motor stator;
- wherein the turbine shell is non-rotatably connected to the rotor via a fixed connection, and wherein the rotor is configured to transfer torque to a transmission input shaft via the fixed connection.
1 more element
A hybrid powertrain comprising:
- a torque converter including an impeller, a turbine, a turbine shell, and a stator, wherein the impeller is configured to receive torque from the engine input shaft without utilizing a torque converter cover;
- and
- an electric machine including a rotor and motor stator, wherein the turbine shell is non-rotatably connected to the rotor and to the transmission input shaft via a fixed connection such that the turbine shell and the rotor can both transfer torque directly to the transmission input shaft.
