Abstract: A one-way clutch includes a first race having a plurality of pockets, each pocket defining a pivot center, a second race including a plurality of notches, a plurality of rockers, each rocker being supported on a respective pocket for pivoting movement about a pivot center relative to the second race, and a spring for urging a rocker toward engagement with a notch.

Abstract: An overrunning one-way clutch includes a cam plate formed with cams angularly spaced about a central axis, and a rocker plate that includes pockets angularly spaced about the central axis. Each pocket includes a first concave surface having a center located within the pocket and through which a pivot axis passes. Each pocket contains a rocker that includes a first convex surface complementary to, and at least partially surrounded by the first concave surface. Springs, supported on the rocker plate, each urge a rocker to pivot about the pivot axis toward the cam plate.

Abstract: A ratcheting one-way clutch includes a cam plate formed with cam surfaces angularly spaced about a central axis, and a rocker plate having pockets angularly spaced about the central axis, each pocket including a surface having a pivot axis located within the pocket. A rocker, located in each pocket, pivots about the pivot axis toward and away from the cam surfaces. Each rocker has a center of mass, located relative to the pivot axis when the rocker is retracted into the pocket away from the cam surfaces, such that an acute angle formed between a first line that extends radially from the central axis through the pivot axis and a second line that passes through the center of mass and the pivot axis is equal to or less than twenty degrees.

Abstract: A one-way clutch includes a first race having mutually spaced pockets formed with an opening at a periphery of the first race, each pocket being at least partially bounded by a wall that extends along at least a portion of a margin of the pocket and contains a drive surface. A second race includes a series of alternating notches and cam surfaces formed on a periphery of the second race facing the openings. A plurality of rockers is located in the pockets. Each rocker includes an engagement surface for driveably engaging and disengaging a notch, a reaction surface for contacting the drive surface when the engagement surface driveably engages a notch, and guide surfaces for contacting the pocket wall to guide movement of the rocker from a disengaged position toward an engaged position. Springs, located on the first race, urge the rockers toward engagement with the cam surfaces.

Abstract: An overrunning one-way clutch includes a cam plate formed with cam surfaces angularly spaced about a central axis and a first journal surface, and a rocker plate including pockets angularly spaced about the central axis, and a second journal surface axially aligned with the first journal surface and spaced radially from the first journal surface by a predetermined distance. Each pocket contains a rocker that is supported in the pocket to pivot toward the cam surfaces. Springs, supported on the rocker plate, each urge a rocker toward the cam surfaces.

Abstract: A one-way clutch includes a cam plate formed with notches, a rocker plate formed with pockets mutually spaced angularly about an axis, each pocket including an open axial end, and a surface that closes each pocket at an end opposite the open axial end of each pocket. A rocker is located in a respective pocket for movement toward and away from engagement with a notch on the cam plate. Springs are supported on the rocker plate, each spring urging a rocker toward engagement with a notch.

Abstract: An overrunning one-way clutch includes a cam plate formed with cam surfaces angularly spaced about a central axis, and a rocker plate including pockets angularly spaced about the axis, each pocket including a surface that closes the pocket at an axial end, an opening located at an axial end opposite the surface, and an aperture facing the cam surfaces. Each pocket contains a rocker supported for pivoting a portion of the rocker through the pocket aperture toward the cam surfaces. Springs supported on the rocker plate, urging each rocker toward an aperture and engagement with the cam surfaces.

Abstract: A carrier assembly for a planetary gearset of a transmission includes a pinion carrier, a one-way brake having a rocker ring integral with the carrier and having multiple pockets mutually spaced about an axis and located on an outer radial surface of the carrier. A cam ring includes multiple notches angularly spaced about the axis and facing the rocker ring. A rocker, located in each pocket, pivots about a pivot center to engage the cam ring, and a spring urges each rocker to pivot toward engagement with the cam ring. A hydraulically actuated friction brake secured to the carrier alternately holds the carrier against rotation relative to a housing and permits the carrier to rotate.
