Hybrid drivetrain
First Claim
1. A drivetrain system for a vehicle, comprising:
- an internal combustion engine, a geartrain, an electric machine, a power take-off unit, a driveline, and a starter rotatably coupled to a crankshaft of the internal combustion engine via a flywheel;
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.

Abstract
A drivetrain system for a vehicle is described, and includes an internal combustion engine, a geartrain, an electric machine, a power take-off unit, and a driveline. The internal combustion engine is coupled to the geartrain via a disconnect clutch and a torque converter. 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. The input member of the differential gearset is coupled to a rotor of the electric machine and the power take-off unit. 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.
