  • Patent number: 11187284
    Abstract: A clutch including: an inner race forming a pocket; an outer race located radially outward of the inner race; a pawl including a portion disposed in the pocket; a cage rotatable by an actuator to a circumferential position with respect to the pawl; and a resilient element fixed to the cage and in contact with the pawl. The inner or outer race is supported for rotation about an axis of rotation. In a first one-way mode: the cage is in the circumferential position; the inner race is relatively rotatable, with respect to the outer race, only in a first circumferential direction; and the resilient element urges the pawl into contact with the outer race. In a second one-way mode: the inner race is relatively rotatable, with respect to the outer race, only in a second circumferential direction; and the resilient element urges the pawl into contact with the outer race.

  • Patent number: 11187278
    Abstract: A friction surface clutch having two conical friction surface pairs each with an inner friction surface element and an outer friction surface element, wherein the inner friction surface element is mounted axially displaceable with respect to a rotational axis, and wherein a frictionally locking connection is set up and canceled in a manner which is dependent on the axial displacement position of the inner friction surface element. The inner friction surface element is coupled to a separate transmission element such that the inner friction surface element and the transmission element can be rotated jointly about the rotational axis, with the coupling being set up via a bearing contact between a guide surface on the inner friction surface element and a countersurface on the transmission element.

  • Patent number: 11168497
    Abstract: A power actuator for a latch of a motor vehicle closure panel has an electric motor to rotate a lead screw about an axis. A nut is disposed about the lead screw for selective translation along the lead screw. A clutch plate is configured for selective rotation about the axis when engaged with the nut, with a biasing member biasing the nut out of engagement with the clutch plate when the electric motor is de-energized. A carrier member is coupled with the nut to cause the nut to translate into engagement with the clutch plate during rotation of the lead screw, whereupon the nut and carrier member co-rotate with the clutch plate and leadscrew. A driven member is operably coupled with the clutch plate and with the latch via a cable/rod, such that the driven member maintains the latch in a cinched state when the electric motor is energized.

  • Patent number: 11156277
    Abstract: The present device includes an inertia ring, a plurality of centrifugal elements, a plurality of cam mechanisms and a plurality of restriction mechanisms. The inertia ring is disposed to be rotatable with a hub flange and be rotatable relatively to the hub flange. Each centrifugal element is disposed to receive a centrifugal force generated by rotation of the hub flange and the inertia ring. When a relative displacement is produced between the hub flange and the inertia ring in a rotational direction while the centrifugal force is acting on each centrifugal element, each cam mechanism converts the centrifugal force into a circumferential force directed to reduce the relative displacement. Each restriction mechanism allows actuation of each centrifugal element by each cam mechanism, and restricts radial movement of each centrifugal element.

  • Patent number: 11125282
    Abstract: A torque limiting assembly is disclosed comprising: an input shaft; an output shaft; and spring having a first end coupled to the input shaft and a second end coupled with the output shaft. In a low torque mode, when the input shaft is rotated the spring is compressed by a low amount and transmits a force to drive rotation of the output shaft, whereas in a high torque mode the spring is compressed by a high amount such that the input shaft rotates relative to the output shaft. This relative rotation moves or urges an engagement member so as to either: disconnect the input shaft from the output shaft; or engage a housing to prevent or inhibit rotation of the input shaft relative to the housing.

  • Patent number: 11111968
    Abstract: A clutch unit includes a clutch having a clutch spring, a motor that generates an actuation driving force for actuating the clutch, an output shaft that transfers the clutch reaction force to the clutch and receives an elastic restoring force of the clutch spring as a clutch reaction force, and a spring that inputs an assist force for assisting the actuation driving force to the output shaft. In switching the clutch from an engaged state to a disengaged state, the output shaft receives the assist force before receiving the clutch reaction force, whereas in switching the clutch from the disengaged state to the engaged state, the assist force becomes zero after the clutch reaction force becomes zero.
