  • Patent number: 10876582
    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.

  • Patent number: 10864813
    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.

  • Patent number: 10760624
    Abstract: Presented are wedge-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes an outer race that attaches to a torque converter's pump cover. The outer race's inner diameter (ID) surface has circumferentially spaced grooves. An inner race is concentrically aligned within the outer race and attaches to an engine's output shaft. The inner race's outer diameter (OD) surface has circumferentially spaced pockets. A wedge plate interposed between the inner and outer races has multiple circumferentially spaced ramps. Each ramp slidably mounts within one groove and one pocket. The wedge plate moves between an engaged position, whereat the ramps wedge between the ID and OD surfaces to thereby transfer torque between the inner and outer races, and a disengaged position, whereat the ramps unwedge to thereby free the inner race to rotate with respect to the outer race.

  • Patent number: 10514096
    Abstract: The continuously variable transmission (CVT) assembly includes a CVT including a drive pulley, a driven pulley, and an endless rotatable device coupled between the drive pulley and the driven pulley. The CVT assembly also includes an actuator coupled to the drive pulley. The CVT assembly also includes an angle sensor coupled to the endless rotatable device such that the angle sensor is configured to measure an angular position of the endless rotatable device. The CVT assembly also includes a controller in communication with the actuator and the angle sensor. The controller is programmed to: (a) determine a speed ratio of the CVT based on the angular position of the endless rotatable device; and (b) control the actuator to adjust the clamping force exerted on the drive pulley in response to determining the speed ratio of the CVT.

  • Patent number: 10267376
    Abstract: A torque transfer mechanism includes an input member to receive an input torque from a propulsion source, and an output member coupled to the input member to transfer the input torque to a driveline component. A multi-component damping mechanism is disposed between the input member and the output member which includes a first spring element cooperating with a second spring element to couple the input member to the output member. The first spring element defines a greater stiffness and shorter deflection relative to the second spring element.
