    Abstract: Disclosed are damper assemblies for engine disconnect devices, methods for making such damper assemblies, and motor vehicles with a disconnect device for coupling/decoupling an engine with a torque converter (TC). A disconnect clutch for selectively connecting an engine with a TC includes a pocket plate that movably mounts to the TC. The pocket plate includes pockets movably seating therein engaging elements that engage input structure of the TC and thereby lock the pocket plate to the TC. A selector plate moves between engaged and disengaged positions such that the engaging elements shift into and out of engagement with the TC input structure, respectively. A flex plate is attached to the engine's output shaft for common rotation therewith. A damper plate is attached to the pocket plate for common rotation therewith. Spring elements mate the damper and flex plates such that the damper plate is movably attached to the flex plate.

    Abstract: An isolator assembly includes a clutch configured to operate in a full locked condition and a slip condition. Additionally, the isolator assembly includes a damper and a centrifugal pendulum absorber (CPA). The damper is configured to reduce oscillation when the clutch is in one of the full locked condition and the slip condition. The damper includes a blade that is biasable. The CPA is coupled to the damper and configured to reduce oscillation when the clutch is in one of the full locked condition and the slip condition.A vehicle includes an engine and a transmission. The engine includes an output shaft and the transmission includes an input member. The vehicle includes the isolator assembly operable between the output shaft and the input member.

    Abstract: Disclosed are latching mechanisms for engine disconnect devices, methods for making and for using such latching mechanisms, and motor vehicles with a disconnect device for coupling/decoupling an engine with a torque converter (TC). A disconnect clutch for selectively connecting an engine with a TC includes a pocket plate that movably mounts to the TC. The pocket plate includes pockets movably seating therein struts that engage notches in a notch plate to lock the pocket plate to the notch plate. A selector plate moves between deactivated and activated positions such that the struts shift into and out of engagement with the notch plate notches, respectively. An activation device is selectively actuable to move the selector plate between activated and deactivated positions. A latching mechanism automatically transitions to a latched state responsive to the selector plate being activated. When latched, this latching mechanism retains the selector plate in the activated position.

    Abstract: A device is configured to control activation of a low-friction clutch, wherein the low-friction clutch includes a first member coaxial to a second member and a controllable activation device interposable therebetween. The device includes a piston that is mechanically coupled to the activation device, a spring that is disposed to urge the piston in a first direction, a controllable electrical coil disposed adjacent to the piston. The electrical coil is disposed to generate an electro-magnetic force to urge the piston in a second direction that is opposed to the first direction when activated, and the spring and the electrical coil interact with the piston to selectively mechanically couple the first and second members via the controllable activation device.
