Wheel hub clutch, wheel hub, wheel end system, axle, drivetrain, and vehicle

A wheel end system, comprising:

• a wheel hub including
• a wheel hub body having
• a hub outboard portion with a hub outboard facing surface having fastener passages therein, and
• a spindle passage, and
• a hub flange extending transversely outwardly and having wheel fastener passages extending therethrough;
• a wheel hub clutch including:
• a selectively rotatable first coupling member including a plurality of locking features, and a wheel hub mounting portion radially outward of the plurality of locking features and coupled to the hub outboard portion of the hub,
• a rotatable second coupling member selectively engageable with the selectively rotatable first coupling member and including a plurality of pockets corresponding to the plurality of locking features of the selectively rotatable first coupling member, and a plurality of passages in communication with the plurality of pockets, and
• a plurality of locking members in the plurality of pockets of the rotatable second coupling member and selectively engageable with the plurality of locking features of the selectively rotatable first coupling member;
• and
• an axle shaft extending through the spindle passage along a rotational axis and including an outboard portion fixed against rotation with respect to the rotatable second coupling member.

A wheel end system including

• a wheel hub including
• a wheel hub body having
• a spindle passage extending along a longitudinal axis, and
• a hub flange extending transversely outwardly from the wheel hub body and having wheel fastener passages extending therethrough, and
• a spindle nut system;
• a hollow spindle extending into the wheel hub body and coupled to the spindle nut system;
• an axle shaft extending through the hollow spindle along a rotational axis and including an outboard portion with engagement features;
• and
• a wheel hub clutch rotatable about the rotational axis and releasably coupling the axle shaft and the wheel hub body, and including
• a coupling assembly, including
• a first coupling member selectively rotatable about the rotational axis and including
• a first face having a plurality of locking features,
• a second coupling member rotatable about the rotational axis and including
• a second face in opposition with the first face of the first coupling member and having a plurality of pockets,
• a third face spaced from the second face and having a plurality of passages in communication with the plurality of pockets,
• a plurality of locking members in the pockets to transmit torque between the first and second coupling members,
• a clutch hub having an interior surface with axle shaft engagement features engaged with the engagement features of the axle shaft to fix the clutch hub to the axle shaft, and
• a control assembly, including
• a stator including at least one electromagnet,
• a stator support disposed radially outwardly from the clutch hub of the coupling assembly, being coupled to the spindle and to the stator to thereby hold the stator against rotation, and
• a translator rotatable about the rotational axis and coupled to the clutch hub to be rotatable therewith and with the second coupling member, translatable along the rotational axis, and including
• a translator hub having
• a main body with
• an interior surface slidable along a translator journal of the clutch hub, and
• an exterior surface including a permanent magnet journal at an inboard portion of the main body, and
• a plunger flange extending radially outwardly from the main body at an outboard portion of the main body,
• a permanent magnet carried by the translator hub and that cooperates with the at least one electromagnet of the stator to translate the translator, and
• plungers having free end portions configured to move within the passages to engage the locking members within the pockets to actuate the locking members upon translation of the translator.
