A disconnectable differential assembly has a reduced axial length and a side gear disconnectable from an axle shaft via a clutch unit. Various components of the disconnect mechanism are axially aligned and concentric to reduce the axial length. An output hub splined on the axle shaft and is actuatable, via an axially shiftable armature, into toothed engagement with the side gear via respective axially extending teeth. The output hub and armature include radially extending flanges that are axially adjacent and radially aligned with the teeth so that force is transmitted to the teeth at the same diameter. A thrust bearing is disposed between the flanges so that the output hub rotates relative to the armature. The side gear is supported for rotation on the axle shaft, and a bearing is disposed radially therebetween to improve radial alignment of the second side gear with the output hub.

Disconnecting differential side gear mechanism

A locking pawl arrangement with a motion compliance mechanism for use with various automotive devices having a rotating hub with a plurality of teeth. There is provided a pawl that is moveable between a disengaged position wherein the pawl is not engaged with the rotating hub, an engaged positioned where the pawl is engaged with the hub and an intermediate position that is between the disengaged position and engaged position. A locking cam is in contact with the pawl and moves between a disengaged position, an engaged position, and an intermediate position against the pawl. There is further provided an actuator that is engageable with the locking cam. The actuator moves between a retracted position and an extended position, thereby causing the locking cam to move the pawl between the intermediate position, disengaged position and engaged position.

Solenoid actuated locking pawl with compliance mechanism

A controllable one-way clutch assembly having an actuator module equipped with a solenoid actuator, an active strut moveable in response to energization of the solenoid actuator from a released position to a locked position, a strut spring biasing the active strut toward its released position, and an indirect strut actuation arrangement between the solenoid actuator and the active strut. The indirect strut actuation arrangement includes an intermediate actuation component having a first lug establishing a coupling interface with a translatable plunger of the solenoid actuator and a second lug establishing an engagement interface with the active strut.

Selectable one-way clutch with solenoid actuator and pivoting actuation member controlling active strut deployment

A selectable one-way clutch includes a clutch module and an electromagnetic actuator module. The electromagnetic actuator module includes an electromagnetic actuator and a strut assembly. The electromagnetic actuator having a coil assembly with a magnetic pole piece. The strut assembly having a strut and a magnetic armature mechanically interconnected to the strut for moving the strut between released and deployed positions in response to energization of the coil assembly. A contamination shroud is disposed between the armature and the pole piece to prevent collection of debris therebetween.

Selectable one-way coupling with debris containment

The subject disclosure relates to a coil module assembly for a bi-directional clutch assembly having at least one active clutch. The coil module assembly includes a housing having an actuator housing portion and a PCB housing portion. An electromagnetic actuator is disposed in the actuator housing portion for effectuating pivotal movement of the active strut from an unlocked position to a locked position in response to an energization of the electromagnetic actuator. An integrated printed circuit board (PCB) is disposed in the PCB housing portion and is in electrical communication with the electromagnetic actuator for selectively energizing the electromagnetic actuator. The housing further includes a thermally decoupled housing portion which is disposed between the actuator housing portion and the PCB housing portion for thermally decoupling, i.e., reducing heat transfer, from the electromagnetic actuator to the PCB during selective energization of the electromagnetic actuator.

Coil module assembly with thermally decoupled solenoid and circuit

A clutch assembly includes an outer race presenting a plurality of outer ratchet teeth and an inner race presenting a plurality of outer ratchet teeth. A selectable one-way clutch includes at least one active strut pivotably supported by the outer race and at least one electromagnetic actuator. The electromagnetic actuator is selectively energized for effectuating pivoting of the active strut from an unlocked position wherein the active strut is disengaged from the outer ratchet teeth to a locked position for engaging one of the plurality of outer ratchet teeth during rotation of the inner race. The clutch assembly includes a lead frame assembly attached to the outer race and electrically connected to the at least one electromagnetic actuator for controlling selective energization of the at least one electromagnetic actuator.

Electronically-controlled selectable clutch assembly with clutch module having integrated safety switch

A bi-directional clutch assembly, method of construction thereof and method of setting a preset gap between a magnetically permeable core and armature thereof is provided, An outer race has inner ratchet teeth and an inner race has outer ratchet teeth. A passive one-way clutch has passive struts pivotally supported for locked engagement with the inner ratchet teeth in a first direction. A selectable one-way clutch has an active strut selectively pivotal from an unlocked position to a locked position for engaging the outer ratchet teeth during rotation of the inner race in a second direction opposite the first direction. A protrusion extends radially outwardly from the outer race and has an orifice extending therethrough. A coil is operably supported by the protrusion. The magnetically permeable core is operably fixed in the orifice to be magnetized by the coil to move the at least one active strut to the locked position.

Electronically-controlled selectable clutch with active strut module and methods of assembly and setting a magnetic gap thereof

A bi-directional clutch assembly includes an outer race presenting a plurality of inner ratchet teeth and an inner race presenting a plurality of outer ratchet teeth. A passive one-way clutch includes a plurality of passive struts supported by the inner race and pivotable into engaging relationships with the inner ratchet teeth during rotation of the inner race in a first direction. A selectable one-way reverse clutch includes at least one active strut supported by the outer race and selectively pivotable from an unlocked position to a locked position to engage one of the outer ratchet teeth during rotation of the inner race in the second direction. The passive struts are unevenly circumferentially spaced from one another along the inner race to establish an indexed relationship among the passive struts for staggering engagement of sequential passive struts with the inner ratchet teeth of the outer race.
