Electromagnetic switchable clutch

An electromagnetic switchable clutch, comprising:

• a dog clutch comprising:
• a dog clutch hub comprising:
• a first outer spline;
• and
• a plurality of first pockets;
• a dog clutch disc comprising a second outer spline;
• and
• a dog clutch sleeve comprising:
• an inner spline, complementary to the first outer spline and the second outer spline, the inner spline drivingly engaged with the first outer spline and axially displaceable to engage the second outer spline;
• and
• a radially-inwardly extending tab;
• a one-way clutch comprising:
• a cam ring rotationally fixed to the dog clutch disc and comprising a plurality of second pockets;
• a plurality of pawls disposed in respective ones of one of the plurality of first pockets or the plurality of second pockets and arranged to engage the other one of the plurality of first pockets or the plurality of second pockets to rotationally lock the cam ring to the dog clutch hub in a single rotational direction;
• and
• a cage comprising:
• a ring portion arranged for pivoting the plurality of pawls;
• and
• a radially-outwardly extending tab;
• and
• a coil assembly arranged to axially displace the dog clutch sleeve, the coil assembly comprising a coil arranged to displace the dog clutch sleeve axially away from the dog clutch disc to pivot the plurality of pawls in a freewheel mode, wherein the radially-inwardly extending tab is arranged to axially displace the radially-outwardly extending tab in a second axial position assigned to the freewheel mode.

• and
• a coil housing comprising:
• an annular portion, aligned with the groove and extending axially between the first cylindrical coil and the second cylindrical coil;
• a first end portion comprising a first conical face;
• and
• a second end portion comprising a second conical face, wherein the armature portion further comprises:
• a third conical face disposed proximate the first conical face in a dog clutch mode;
• and
• a fourth conical face disposed proximate the second conical face in a freewheel mode.
