Overrunning coupling and control assembly, coupling assembly and locking member having at least one side surface with a draft to improve locking member dynamics are provided. Locking member dynamics is improved with regards to locking member laydown speed. Laydown speed variation cause by a variable frictional coefficient between a pocket surface of a pocket in which the locking member is received and nominally retained and the at least one side surface of the locking member is minimized as well.

A coupling and electromechanical control assembly and an electromechanical system for controlling the operating mode of a selectable clutch assembly are provided. The system includes a control member mounted for controlled rotation about a first axis. An actuator and transmission assembly includes a rotary output shaft and a set of interconnected transmission elements including a cam coupled to the output shaft to rotate therewith and a reciprocating member having a first end which rides in or on the cam to cause the reciprocating member to reciprocate upon rotation of the output shaft. A second end of the reciprocating member is coupled to the control member for selective, small-displacement, control member angular rotation about the first axis between different angular positions which correspond to different operating modes of the clutch assembly.

A driving device includes a first one-way clutch OWC1 provided on a power transmission path between a driving source and a driven portion which becomes in an engaged state when rotational power in one direction of the driving source side is input to the driven portion side and becomes in a disengaged state when rotational power in the other direction of the driving source side is input to the driven portion side and which becomes in a disengaged state when rotational power in one direction of the driven portion side is input to the driving source side and becomes in an engaged state when rotational power in the other direction of the driven portion side is input to the driving source side, a connection/disconnection unit which is provided in parallel with the first one-way clutch OWC1 on the power transmission path, and a second one-way clutch OWC2 provided in parallel with the first one-way clutch OWC1 and in series with the connection/disconnection unit on the power transmission path which performs an operation opposite to that of the first one-way clutch OWC1.

A control device for a selectable one-way clutch includes a pocket plate; a notch plate rotating relative to the pocket plate; a selector plate between the pocket plate and the notch plate rotating coaxially with the notch plate to change between a state allowing engagement members to pass through respective openings and to stand up from a side close to the pocket plate toward a side close to the notch plate and a state allowing the housing recesses to house the engagement members; and a motion detection unit detecting a motion of the selector plate. Further, when an unintended motion of the selector plate is detected, the pocket plate and the notch plate to rotate differentially at a rotation speed equal to or less than a predetermined absolute value, and the selectable one-way clutch to fall into a state of ratchet or into a state of overrun.

A selectable one-way clutch includes: a pocket plate including accommodating recess portions; a notch plate including engaging recess portions; a plate-shaped engaging piece; and a selector plate configured to switch between: a state in which the engaging piece rises toward the notch plate; and a state in which the engaging piece is accommodated in the accommodating recess portion. The notch plate includes a plane portion including a first inclined surface, and the first inclined surface provides the engaging piece with force in a direction into which the engaging piece is urged away from the notch plate, when the notch plate is rotated in an engaging direction into which the engaging piece rising toward the notch plate is engaged with the engaging recess portion, and one end portion of the engaging piece rises toward the notch plate and comes in contact with the plane portion.

An electronic, high-efficiency vehicular transmission, an overrunning, non-friction coupling and control assembly and switchable linear actuator device for use in the assembly and the transmission are provided. The device controls the operating mode of at least one non-friction coupling assembly. The device has a plurality of magnetic sources which produce corresponding magnetic fields to create a net translational force. The net translational force comprises a first translational force caused by energization of at least one electromagnetic source and a magnetic latching force based upon linear position of a permanent magnet source along an axis.

A controllable coupling assembly having substantially no backlash is provided. The assembly includes a set of reverse locking formations each of which includes a load bearing surface having a sloped geometry and being adapted to lock a reverse locking element in place along the load bearing surface based on a mechanical tolerance between load bearing surfaces of forward and reverse locking elements through a wedging effect to prevent relative rotation between first and second coupling members of the assembly in a reverse direction about a rotational axis, to absorb at least a portion of the tolerance and to substantially eliminate any backlash between the locking elements.

An electromagnetic system for controlling the operating mode of a non-friction coupling assembly and a coupling and magnetic control assembly are provided. Magnetic circuit components include a ferromagnetic or magnetic element received within a pocket of a coupling member. The element controls the operating mode of the coupling assembly. A stationary electromagnetic source includes at least one excitation coil which generates a magnetic field between poles of the source when the at least one coil is supplied with current. Ferromagnetic or magnetic first and second inserts are received and retained within first and second spaced passages, respectively, of the coupling member. The electromagnetic source, the element, the inserts and air gaps between the various magnetic circuit components make up a closed loop path containing magnetic flux so that the element moves between first and second positions of the element when the at least one coil is supplied with current.

A coupling and control assembly including a non-contact, inductive displacement sensor is provided. The assembly includes a controllable coupling assembly including first and second coupling members supported for rotation relative to one another about a rotational axis. The first coupling member has a first coupling face which has a sensor pocket which receives the sensor. A control member made of an electrically conductive material is mounted for controlled, small-displacement, shifting movement relative to the sensor. The sensor is configured to create a magnetic field to induce eddy currents in the electrically conductive material of the control member wherein shifting movement of the control member changes a magnetic field caused by the eddy currents. The sensor provides a position feedback signal for vehicle transmission control, wherein the signal is correlated with the position of the control member.

Systems and methods are presented herein for providing an integrated disconnect. The integrated disconnect may be used within a drive unit. The integrated disconnect comprises an output gear having a cavity. A torque transfer adapter is arranged within the cavity. A clutch body is also arranged within the cavity. The clutch is actuatable through the output gear by an actuator to engage and disengage the clutch with the torque transfer adaptor. The actuator is located external to the cavity.
