Hybrid drivetrain

A drivetrain system for a vehicle, comprising:

• an internal combustion engine, a geartrain, an electric machine, a power take-off unit, and a driveline;
• wherein the internal combustion engine is coupled to the geartrain via a disconnect clutch and a torque converter;
• wherein the geartrain includes a transmission and a differential gearset, including an output member of the transmission coupled to an input member of the differential gearset;
• wherein the input member of the differential gearset is coupled to a rotor of the electric machine and the power take-off unit;
• and
• wherein the differential gearset is coupled to first and second intermediate driveshaft members of the driveline to transfer propulsion power to vehicle wheels that are arranged in a front-wheel configuration;
• and
• wherein the input member of the differential gearset is coupled to the power take-off unit to transfer propulsion power to vehicle wheels disposed in a rear-wheel location.

A drivetrain system for a vehicle, comprising:

• an internal combustion engine and an electric machine being coupled to a geartrain that is coupled to a driveline;
• the geartrain including a torque converter, a transmission, a differential gearset, and a disconnect clutch, wherein the torque converter is coupled to an input member of the transmission;
• the driveline including first and second intermediate driveshaft members coupled to vehicle wheels disposed in a front-wheel drive configuration, wherein the first and second intermediate driveshaft members are coupled to the differential gearset;
• wherein the internal combustion engine includes a crankshaft that is coupled to the torque converter and a starter rotatably coupled to the crankshaft of the internal combustion engine via a flywheel,
• wherein the disconnect clutch is disposed to disconnect an element of the geartrain from the driveline;
• wherein the differential gearset includes an input member;
• wherein the input member of the differential gearset is coupled to a power take-off unit;
• and
• wherein the input member of the differential gearset is coupled to an output member of the transmission and a rotor of the electric machine.
