  • Publication number: 20160076646
    Abstract: A dog clutch operable to bypass a variator of a transmission is disclosed. The dog clutch includes a housing engaged with an input ring of the variator. The dog clutch also includes a piston engaged with the housing and movable from a first position in which the piston is disengaged from an output ring of the variator to a second position in which the piston is engaged with the output ring. The variator input ring and output ring are locked together when the dog clutch is in the second position to prevent the variator from producing continuously variable torque output. The variator is operable to produce continuously-variable torque output when the dog clutch is in the first position.

  • Patent number: 9022194
    Abstract: The present disclosure provides an actuation assembly for applying a mechanical diode clutch. The clutch includes an outer member, an inner member, and a strut. The actuation assembly includes a plate having an apply portion and a plurality of legs, where each of the plurality of legs has a first end coupled to the apply portion and a second end adapted to couple to a shift sleeve. A mechanism is coupled to the apply portion of the plate. The mechanism includes at least one biasing member. The plate is moveable between an unapply position and an apply position such that a movement from the unapply position to the apply position induces contact between the mechanism and the strut.

  • Patent number: 8910666
    Abstract: An apparatus for axially transferring fluid may comprise an elongated shaft defining a first fluid passageway axially therethrough and a second fluid passageway from an outer surface thereof to the first fluid passageway. An elongated tube member defines an outer surface that is received within the first fluid passageway and a third fluid passageway axially therethrough. A plurality of axial channels are defined between the tube member and the first fluid passageway or along the tube member separately from the third fluid passageway. At least one of the plurality of axial channels define a first opening near one end thereof that receives fluid from a source of fluid and a second opening axially spaced apart from the first opening and that aligns with the second fluid passageway such that fluid may be transferred by the at least one fluid passageway from the source of fluid through the second fluid passageway.

  • Patent number: 8747014
    Abstract: An assembly comprises a shaft defining a longitudinal axis, a first component supported on the shaft, a second component supported on the shaft, and an isolator positioned between the first component and the second component. The second component configured such that the second component induces a force having a component parallel to the axis of the shaft. The force component parallel to the axis of the shaft induced by the second component is transferred directly to the shaft by the isolator and is isolated from the first component.

  • Patent number: 8617026
    Abstract: A mode shift assembly for a transmission comprises has a first side coupled to a rotational input, a second side coupled to a rotational output, and an actuator. The actuator acts on the first side to move the first side between a first position in which the first and second engagement surfaces are disengaged and a second position. In the first position, rotation between the first and second sides is independent. In the second position, the first and second engagement surfaces are engaged such that rotation is transferred from the first side to the second side.
