  • 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: 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: 7938147
    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.

  • Publication number: 20060027435
    Abstract: A torque-transmitting mechanism has a plurality of friction plates, which are forced into engagement by a fluid-operated piston and reacted in engagement by a backing plate. The backing plate is assembled on a rotatable shaft to be aligned with splines on the shaft to prevent axial removal of the backing plate without rotation thereof which is restricted due to a spline engagement between the backing plate and the shaft.

  • Publication number: 20050206253
    Abstract: A motor resolver assembly includes a resolver stator and a resolver rotor positioned radially inward of and rotatable with respect to the resolver stator. First and second relatively rotatable shield components generally surround the resolver stator and rotor to shield them from electromagnetic energy from a radially outward motor rotor and motor stator. A method of measuring speed and position of the motor rotor relative to the motor stator is also employed.
