Patent number: 11846326Abstract: An actuating assembly includes a body; a plunger axially movable with respect to the body; a linear actuator configured for being activated to axially move the plunger in a first direction into engagement with the body such that the plunger and body are rotationally fixed with respect to each other; a barrel movable with respect to the body for contacting the plunger and the body depending on an axial position of the plunger; and a spring for biasing the barrel toward the plunger. The barrel is configured such that the spring forces the barrel into circumferential engagement with the body in two different axial positions of the barrel with respect to the body when the linear actuator is inactive depending on a rotational orientation of the barrel.Type: GrantFiled: October 5, 2022Date of Patent: December 19, 2023Assignee: Schaeffler Technologies AG & Co.

Patent number: 11215243Abstract: A clutch assembly comprises an actuation assembly, an outer ring, and an inner ring disposed radially inward of the outer ring and rotatable about an axis in first and second rotational directions. A first and second strut are rotatably disposed within first and second pockets of the outer ring and configured to be rotated by the actuation assembly. A first pawl and a second pawl are rotatably disposed within a third pocket and a fourth pocket, respectively. For a transition mode, the actuation assembly is configured to rotate the first strut within the first pocket such that rotation of the first strut in the first rotational direction urges the first pawl radially inward into partial engagement with teeth disposed on an outer surface of the inner ring, the second pawl remains free of contact with the inner ring and the inner ring rotates in the first rotational direction.Type: GrantFiled: October 2, 2020Date of Patent: January 4, 2022Assignee: Schaeffler Technologies AG & Co.

Patent number: 10815843Abstract: A switchable one-way clutch (SOWC) is configured to operate in both a freewheeling mode and a one-way clutch mode. The SOWC includes an inner race with a plurality of external cams, and a cylindrical outer race. A plurality of rollers are disposed radially between the inner cams and the outer race. A cage is connected to an outer phaser and includes a plurality of tabs. An inner phaser has a plurality of lobes extending radially outwardly, and the outer phaser has a plurality of inwardly-extending portions. The lobes and the inwardly-extending portions cooperate to define chambers. When fluid is applied to the chambers, the outer phaser rotates relative to the inner phaser. This causes the cage to rotate along with the outer phaser. When the cage rotates, its tabs move away from the rollers, enabling the assembly to function as a one-way clutch.Type: GrantFiled: May 9, 2018Date of Patent: October 27, 2020Assignee: SCHAEFFLER TECHNOLOGIES AG & CO.

Patent number: 8011641Abstract: A carburettor includes a flow duct (4) including rich (8) and lean (10) passages in parallel, through which, in use, air flows and which are separated by a substantially planar partition (6). At least one fuel jet (12, 14, 16) communicates with the rich passage (8). The partition (6) includes a circular aperture (20). A butterfly valve (24) is mounted on a pivotal shaft (22) to be pivotable between a closed position, in which the flow duct (4) is substantially closed, and an open position, in which the flow duct is substantially open. The pivotal shaft (22) extends perpendicular to the plane of the partition (6). The pivotal shaft (22) carries a circular obturator disc (26), whose diameter is substantially equal to that of the aperture (20) and which is received in the aperture (20) and substantially closes the aperture (20) at all positions of the butterfly valve (24).Type: GrantFiled: July 20, 2007Date of Patent: September 6, 2011Assignee: Ricardo UK LimitedInventor: James Copeland
