Abstract: A drive unit for a hybrid module includes a housing assembly and an electric motor including a stator and a rotor. The stator is fixed to the housing assembly. The drive unit further includes an assembly configured for rotatably connecting the rotor to an internal combustion engine. The assembly includes a shaft configured for connecting to the internal combustion engine, a rear bearing on the shaft and a bearing housing on an outer race of the rear bearing. The bearing housing axially abuts the rear bearing so the rear bearing limits rearward axial movement of the bearing housing.

Abstract: A rotor assembly includes a torque converter including a housing forming a hydraulic chamber, a rotor for an electric motor, a rotor carrier non-rotatably connected to the rotor that is fixed to the torque converter housing, a rotor carrier flange, a spring, and a snap ring. In some embodiments, the rotor carrier includes a groove and a castellated portion, the snap ring is disposed in the groove, and the spring clamps the rotor carrier flange between the snap ring and the castellated portion.

Abstract: A torque converter includes a cover, an impeller including an impeller engagement section, an axially movable turbine piston including a turbine engagement section configured for engaging the impeller engagement section to form a lockup clutch and a coast engagement structure configured for contacting the cover to limit axial movement of the turbine piston away from the impeller in a coast condition.

Abstract: A motor assembly for a hybrid vehicle includes an electric motor, a shaft, a multiplate clutch, and a housing. The electric motor has a rotatable rotor with a carrier. The shaft is arranged for drivingly engaging a combustion engine. The multiplate clutch is drivingly engaged with the carrier for releasably engaging the electric motor to the shaft. The housing includes a center support with a hydraulic channel extending from radially outside of the electric motor to radially inside of the electric motor. In an example embodiment, the motor assembly has a torque converter fixed to the carrier. In some example embodiments, the motor assembly has a concentric slave cylinder for engaging the clutch. The concentric slave cylinder is hydraulically connected to the center support hydraulic channel. In an example embodiment, the motor assembly has a pressing plate in contact with the slave cylinder and the multiplate clutch.

Abstract: A hybrid drive module, comprising a cover of a torque converter. The hybrid drive module further includes a carrier hub connected to a rotor of an electric motor and the cover, the hub including a first surface and a protrusion extending outward from the first surface. The hybrid drive module also includes an end ring disposed between the protrusion and the rotor and in contact with the first surface, wherein the end ring is engaged with the protrusion and the rotor, and the protrusion restrains the end ring and rotor utilizing an interference fit between the carrier hub and the end ring.

Abstract: A rotor assembly includes a torque converter including a housing forming a hydraulic chamber, a rotor for an electric motor, a rotor carrier non-rotatably connected to the rotor that is fixed to the torque converter housing, a rotor carrier flange, a spring, and a snap ring. In some embodiments, the rotor carrier includes a groove and a castellated portion, the snap ring is disposed in the groove, and the spring clamps the rotor carrier flange between the snap ring and the castellated portion.

Abstract: A drive assembly for a motor vehicle drive train is provided. The drive assembly includes a first subassembly configured for connecting to an engine crank. The first subassembly includes a slip clutch plate. The drive assembly also includes a second subassembly connected to the first subassembly via a radially outer portion of the slip clutch plate. The second subassembly includes a damper assembly. A method of forming a drive assembly for a motor vehicle drive train is also provided.
