A vehicle wheel hub assembly comprising an axle element that is rotationally stationary about an axial axis, and a hub shell element rotatable about the axle element, including a first end portion and a second end portion axially spaced from said first end portion. The axle element includes a control shaft that is axially displaceable relative to the hub shell element between an axially extended position and an axially retracted position. The control shaft includes an engagement end and a control end. In the extended position, the engagement end is axially distal from the second end portion and, in the retracted position, the engagement end is axially proximal to the second end portion relative to said extended orientation. Including a releasable axial retaining means to control the axial movement of the control shaft relative to the hub shell. |

1. A vehicle wheel hub assembly, comprising:
an axle element that is rotationally stationary about an axial axis; a hub shell element that is rotatable about said axle element and about said axial axis, including a first end portion and a second end portion axially spaced from said first end portion; a control shaft that is internally coaxial with said axle element and axially displaceable relative to said axle element between an axially extended position and an axially retracted position, wherein said axial displacement is in a retracting direction toward said retracted position and an extending direction opposed to said retracting direction and toward said extended position; wherein said control shaft includes an engagement end and a control end axially opposed said engagement end, wherein said control shaft may be manipulated adjacent said control end; wherein, in said extended position, said engagement end is axially outward relative to said retracted position; including a releasable axial retaining means between said control shaft and said axle element at a retaining interface to restrain the axial displacement of said control shaft relative to said axle element; wherein said retaining means may be selectively released to permit said axial displacement of said control shaft relative to said axle element; and wherein, when said axial retaining means is released, the axial displacement of said control shaft may be manipulated independently of a circumferential displacement of said control shaft relative to said axle element. |
