This disclosure details cooling systems for cooling electric components, such as electric machines, within electrified vehicles. Exemplary cooling systems may include a spray bar positioned relative to a rear face of a stator of the electric machine. In some embodiments, the spray bar may be positioned axially between the rear face of the stator and a torque converter housing. One or more nozzles of the spray bar are configured to direct a coolant between adjacent back irons of the stator, onto end windings of the stator, or both. Actively cooling the stator allows the electric machine to operate at higher torques and speeds, thereby increasing performance.

Cooling systems for cooling electric machines within electrified vehicles

Methods and systems for an electric motor-generator in a vehicle are provided. In one example, an electric motor-generator is provided that includes an engine interface configured to rotationally couple to a first engine, a transmission interface configured to rotationally couple to a first transmission of the first engine, and a rotor with a plurality of magnets at least partially surrounding a stator including a plurality of coils. The rotor is rotationally coupled to the engine interface and the transmission interface.

Electric motor-generator in a vehicle system and method for operation of said motor-generator

Methods and systems are provided for a cooling jacket for a stator. In one example, the cooling jacket is cast as a single piece with windings of the stator pressed into a surface of the cooling jacket.

This disclosure details transmission systems for electrified vehicles. Exemplary transmission systems may include a crankshaft integrated starter-generator. The crankshaft integrated starter-generator may include an electric machine and an integrated rotor carrier/input shaft assembly. The integrated rotor carrier/input shaft assembly is configured to support the electric machine and provide an interface for mounting the crankshaft integrated starter-generator relative to a torque converter. The torque converter may be mounted to a flange of the integrated rotor carrier/input shaft assembly that is inside the diameter of a rotor of the electric machine.

Hybrid transmission systems including crankshaft integrated starter-generators

A transmission is provided. The transmission may include a planetary gearset. The transmission may also include a thrust hub that may be fixed to the planetary gearset and engaged with a thrust bearing. A clutch hub may be connected with and spaced away from the thrust hub such that the thrust and clutch hubs are not in contact with each other to reduce vibration transfer between the thrust and clutch hubs.
