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.

A transmission assembly for a work vehicle having an engine includes a variator operably connected to the engine, a gear arrangement configured to provide a selective gear reduction for transmission of output power from the variator to an output shaft, and an electrical machine unit. The electrical machine unit further includes a main shaft operably connected to the variator, a first rotor configured to rotatably drive a first shaft, a second rotor configured to rotatably drive a second shaft, and a clutch configured to selectively couple the first shaft or the second shaft, or both the first shaft and the second shaft, to the main shaft. The clutch, the first rotor, and the second rotor are operable to control a speed and rotational direction of the main shaft in providing rotational power to the variator.

Provided herein is an auxiliary hybrid system (AHS) that may be configured to provide electrical propulsion to an e.g., internal combustion-powered vehicle through the use of a battery and electric motor. Alternatively, the AHS may be configured to increase range to electric vehicles through the use of an internal combustion-powered generator. In either embodiment, the AHS is added to a vehicle without altering the operation of the vehicles' standard drivetrain, allowing the vehicle to operate conventionally when the AHS is not engaged. The AHS is compatible with a wide range of vehicles with a minimum of vehicle-specific parts.

A hybrid drive apparatus is provided to allow setting a variety of driving modes while achieving improvement in transmission efficiency. The hybrid drive apparatus includes an engine, first and second motor generators and a planetary gear mechanism. An output shaft of the first motor generator, an output shaft of an engine and an output shaft of the second motor generator, and an input shaft of the continuously variable transmission mechanism are coupled respectively to a sun gear, ring gear and carrier of the planetary gear mechanism. The hybrid drive apparatus includes first, second and third clutches which can switch engagement/disengagement respectively between the output shaft of the engine and the ring gear, between the carrier and the ring gear, and on the input shaft of the continuously variable transmission mechanism.
