Abstract: Presented are clutch-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes a notch plate, which has multiple notches and attaches to a torque converter, and a pocket plate, which has multiple pockets and attaches to an engine's crankshaft. A pawl is movably mounted within each notch; these pawls selectively engage the notches with the pockets. A notch plate insert is nested within each notch, supporting thereon one of the pawls. A selector plate interposed between the pocket and notch plates moves from a first position, to shift the pawls out of engagement with the pockets, and a second position, to move the notch plate inserts within the notches and allow the pawls to engage the notches with the pockets to thereby lock the notch plate to the pocket plate to rotate in unison with each other.

Abstract: Rotor for electric machines and methods for fabricating rotors for electric machines are provided. An exemplary method includes assembling a stack of laminations to form a rotor core having an external surface. The rotor core defines one to five layers of internal cavities and an interior permanent magnet is positioned in a selected internal cavity. The method also includes locating a non-magnetic structural element in the selected internal cavity. Further, the method includes applying a compressive force on the external surface of the rotor core with an annular sleeve.

Abstract: A stator assembly for an electric motor includes a laminate steel core arranged on an axis. The stator assembly also includes a fluid inlet and a fluid outlet. The stator assembly additionally includes a stator housing arranged on the axis concentrically with respect to the laminate steel core. The stator housing has a conduit fluidly connected to each of the fluid inlet and the fluid outlet and configured to circulate fluid around the laminate steel core. The stator assembly also includes a structural skeleton embedded in the stator housing. The structural skeleton is thereby configured to reinforce the stator housing. An electric motor employing the above-described stator assembly is also contemplated.

Abstract: A vehicle powertrain includes a first power-source configured to generate a first power-source torque and a multiple speed-ratio transmission configured to transmit the first power-source torque to power the vehicle. The powertrain also includes a fluid coupling having a fluid pump shaft operatively connected to the first power-source and a turbine shaft operatively connected to the multi-speed transmission. The fluid coupling is configured to multiply the first power-source torque, and transfer the multiplied first power-source torque to the multiple speed-ratio transmission. The powertrain additionally includes a second power-source configured to generate a second power-source torque and a first torque transfer system configured to connect the second power-source to the first power-source. The powertrain further includes a second torque transfer system configured to connect the second power-source to the multi-speed transmission. A motor vehicle having such a powertrain is also envisioned.

Abstract: Presented are dual-clutch engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device for a vehicle includes a first one-way clutch (OWC) with concentric inner and outer races and torque elements interposed between and transferring torque across these races in a first direction. The first outer race rigidly attaches to a damper plate for common rotation therewith, and the first inner race rigidly attaches to a pump cover of a torque converter for common rotation therewith. A second OWC, which concentrically aligns within the first OWC, includes concentric inner and outer races with torque elements interposed between and transferring torque across these races in a second direction. The second outer race is splined to the first inner race for common rotation with the pump cover. The second inner race rigidly attaches to the damper plate for common rotation therewith.

Abstract: A cycloidal reluctance machine includes a stator surrounding a rotor. Stator windings and rotor windings form respective concentric rotor and stator electromagnets. The rotor is eccentrically positioned with respect to the stator to move with two degrees of freedom (2DOF), including rotating motion about a rotary axis of the rotor and orbiting motion about a center axis of the stator. A rotor constraint mechanism (RCM) constrains motion of the rotor, such that the rotor is able to generate and transmit output torque to a coupled load in at least one of the 2DOF. A magnetic field polarity of stator poles and/or rotor poles of the respective stator and rotor changes over one electrical cycle of the polyphase voltage. The coupled load may be a drive axle of a vehicle in some embodiments. In others, the stator and rotor windings are driven via different power inverters.
