Abstract
An actuation mechanism for use with a coupling device. The actuation mechanism includes an assembly having a hub, a latch member, a translating member, and an indexer. The assembly includes a carrier supported on the hub that engages the indexer. The carrier moves axially relative to the hub. A return member biasing the indexer to a non-deployed position, with the translating member acting against the return member to move the indexer to the deployed position.
Claims19
An assembly comprising:
- a hub, the 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 side surface extending between an inner and an outer circumferential surface of the first member, the side surface of the first member including a cam surface;
- a second member rotatably fixed and axially movable with respect to the first member, the second member having a side surface extending between an inner and an outer circumferential surface of the second member, the side surface of the second member including a cam surface;
- a third member rotatably and axially movable with respect to the shaft, the third member having a side surface extending between an inner circumferential surface and an outer circumferential surface, the side surface of the third member including a first cam surface and a second cam surface extending at a same angle, the second cam surface of the third member radially inward of the first cam surface of the third member, the third member having a groove in the inner circumferential surface of the third member;
- and
- the cam surface of the first member is in the groove of the third member when the assembly is placed in a retracted position, and the cam surface of the first member contacts the second cam surface of the third member when the assembly is placed in an extended position.

An assembly comprising:
- a first member having a cylindrically shaped body, a cam face and an end face opposite the cam face, the first member including a plurality of projections and grooves on an outer circumferential surface of the first member;
- a second member having a cylindrically shaped body, a cam face and a plurality of projections and grooves on an inner circumferential surface of the second member, the projections and grooves on the inner circumferential surface of the second member complementary to the projections and grooves on the outer circumferential surface of the first member wherein engagement of the projections and grooves on the outer circumferential surface of the first member with the 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 cam face of the second member spaced radially from and concentric with the cam face of the first member;
- a third member having a cylindrically shaped body, a cam face and a plurality of projections and grooves on an inner circumferential surface of the third member, the cam face of the third member including a first cam face and a second cam face, the first and second cam faces have a common border;
- and
- the first cam face of the third member engages the cam face of the second member, and the second cam face of the third member engages the cam face of the first member.
3 more elements
An assembly comprising:
- a hub, the hub including a shaft rotating about a longitudinal axis;
- a first member secured to the hub and constrained against rotational and axial movement with respect to the hub, the first member having a side surface extending between an inner and an outer circumferential surface of the first member, the side surface of the first member including a cam member;
- a second member rotatably fixed and axially movable with respect to the first member, the second member having a side surface extending between an inner and an outer circumferential surface of the second member, the side surface of the second member including a cam member;
- a carrier carried on the hub, the carrier having a cylindrical body and a radially outwardly extending flange;
- a third member positioned over the cylindrical body and rotating around the cylindrical body, the third member rotatably and axially movable with respect to the shaft, the third member having a side surface extending between an inner circumferential surface and an outer circumferential surface, the side surface of the third member including a first cam member and a second cam member, the second cam member of the third member radially inward of the first cam member of the third member, and the third member having a groove in the inner circumferential surface of the third member;
- and
- the cam member of the first member is in the groove of the third member when the assembly is placed in a retracted position, and the cam member of the first member contacts the second cam member of the third member when the assembly is placed in an extended position.
