Wheel hub clutch actuation mechanism, wheel end disconnect, and wheel end system

A wheel hub clutch actuation mechanism, comprising:

• a hub including a shaft;
• a first member secured to the hub and constrained against rotational and axial movement with respect to the hub, the first member having a first side surface extending between a first inner and a first outer circumferential surface of the first member, the first side surface of the first member including a first cam surface;
• a second member rotatably fixed and axially movable with respect to the first member, the second member having a second side surface extending between a second inner and a second outer circumferential surface of the second member, the second side surface of the second member including a second cam surface;
• a third member rotatably and axially movable with respect to the shaft, the third member having a third side surface extending between a third inner circumferential surface and a third outer circumferential surface, the third side surface of the third member including a third cam surface and a fourth cam surface, the fourth cam surface of the third member radially inward of the third cam surface of the third member, the third member having a groove in the inner circumferential surface of the third member;
• and
• the first cam surface of the first member is in the groove of the third member when the mechanism is placed in a retracted position, and the first cam surface of the first member contacts the fourth cam surface of the third member when the mechanism is placed in an extended position.

A wheel hub clutch actuation mechanism, comprising:

• a first member having a first cylindrically shaped body, a first cam surface extending transversely to a first rotational axis of the first member, and an end opposite the first cam surface, the first member including a first plurality of projections and grooves on an outer circumferential surface of the first member;
• a second member having a second cylindrically shaped body, a second cam surface extending transversely to a second rotational axis of the second member, and a second plurality of projections and grooves on an a second inner circumferential surface of the second member, the second projections and grooves on the inner circumferential surface of the second member complementary to the first projections and grooves on the outer circumferential surface of the first member wherein engagement of the first projections and grooves on the outer circumferential surface of the first member with the second projections and grooves on the inner circumferential surface of the second member allows axial movement and prevents rotational movement between the first member in the second member;
• the second cam surface of the second member spaced radially from and concentric with the first cam surface of the first member;
• a third member having a third cylindrically shaped body, a third member cam surface extending transversely to a third rotational axis of the third member, and a third plurality of projections and grooves on a third inner circumferential surface of the third member, the third member cam surface of the third member including a third member first cam surface and a third member second cam surface, wherein third member first and second cam surfaces are concentric;
• and
• the third member first cam surface of the third member engages the second cam surface of the second member, and the third member second cam surface of the third member engages the first cam surface of the first member.
