A bi-directional clutch assembly equipped with a pair of laterally-spaced, selectable one-way clutches configured in a compact arrangement. The bi-directional clutch assembly establishes a LOCK-LOCK mode when both SOWC's are non-actuated, establishes a FREEWHEEL mode when both SOWC's are actuated, and establishes a pair of LOCK-RATCHET mode when one SOWC is actuated and the other is not actuated. Coils units of the SOWC's are energized to shift an actuator toward active struts of an outer race. The actuator is rotationally fixed to the outer race. The active struts are biased toward the deployed position, and the actuator is biased toward the non-actuated position. The actuator includes a strut engagement feature that contacts the active struts and causes pivotal movement of the active struts to the non-deployed position.

Rotating e-clutch assembly providing four operating modes

A controllable one-way clutch assembly having an electromagnetic actuator module equipped with an energizeable coil assembly, a strut moveable in response to energization of the coil assembly from a released position to a locked position, and a latching mechanism operable to releaseably hold the strut in the released position when the coil assembly is not energized.
