A hybrid module includes a rotor carrier, a rotor, first and second pluralities of clutch plates, an input, a spring element, and first and second torsion dampers. The rotor carrier has a first outer circumferential surface and an inner circumferential surface with a first spline. The rotor is fixed to the first outer circumferential surface. The first plurality of clutch plates is drivingly connected to the first spline. The input has a second outer circumferential surface with a second spline. The second plurality of clutch plates is drivingly connected to the second spline. The spring element is for compressing the clutch plates to transmit a clutch torque. The first torsion damper is arranged in a first torque path between the input and an engine. The second torsion damper is arranged in a second torque path between the rotor carrier and a multi-speed transmission.

A torque converter assembly includes an input plate connectable to a powerplant, a torque converter, and a disconnect clutch external to the torque converter and configured to selectively couple the input plate to the torque converter. The torque converter includes a cover having an outer surface and at least one fluid hole extending through the cover. The disconnect clutch is actuated by pressurized fluid via the fluid hole.

Presented are torque converters with integrated engine disconnect devices, methods for making/using such torque converters, and electric-drive vehicles equipped with such torque converters. A torque converter (TC) assembly includes a TC housing that drivingly connects to an engine output member. A TC output member projects from the TC housing and drivingly connects to a transmission input member. A turbine with a bladed turbine shell is mounted on the TC output member and rotatable within the TC's internal fluid chamber. An impeller with a bladed impeller shell is juxtaposed with the turbine and rotatable within the fluid chamber. An engine disconnect device, which is disposed within the fluid chamber between the impeller shell and TC housing, drivingly couples the impeller to and, when desired, drivingly decouples the impeller from the TC housing and engine output member to thereby transfer torque and prevent torque transfer, respectively, between the engine and transmission.

The cover plate is fixed to and radially inside of the rotor carrier, and includes a tubular portion with an orifice. The connecting pin is sealed to the tubular portion and extends through the orifice. The piston is disposed on a first axial side of the cover plate, is fixed to the connecting pin, and is arranged to engage a torque converter clutch, and the pressure plate is disposed on a second axial side of the cover plate, opposite the first axial side, is fixed to the connecting pin, and is arranged to engage a K0 clutch.

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.

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.

A vehicle includes the assembly operable between an output shaft of an engine and an input member of a transmission. The assembly includes a damper and a clutch operable between the pump and the turbine. The damper is operable upstream from the clutch such that oscillation from the pump is reduced by the damper before oscillation reaches the clutch. The clutch includes first and second plates and a friction plate disposed between the first and second plates. The assembly includes a casing that contains the pump, the turbine, the damper and the clutch. A first part of the casing and the first plate define a first chamber. A first part of the turbine and the second plate define a second chamber. The clutch between the first and second plates defines a third chamber.
