Vehicle wheel axle assembly

A vehicle wheel axle assembly, comprising:

• an axle sleeve that is rotationally stationary about an axial axis and that includes:
• a first end face;
• a second end face axially spaced from said first end face;
• an axially extending opening therethrough;
• and a radially extending first engagement surface;
• a control shaft including:
• an engagement end;
• a control end axially opposed said engagement end;
• and a radially extending second engagement surface;
• wherein said control shaft extends within said opening to be axially overlapping said axle sleeve with said engagement end proximal said first end face and distal said second end face;
• wherein said control shaft is axially displaceable relative to said axle sleeve in an extending direction toward said first end face and an retracting direction axially opposed to said extending direction and toward said second end face;
• wherein said control shaft is axially retained to said axle sleeve by means of an overlie engagement at an engagement interface between said first engagement surface and said second engagement surface;
• wherein at least one of said first engagement surface and said second engagement surface is a radially displaceable engagement surface such that said radially displaceable surface may be radially displaced between an engaged orientation corresponding to said overlie engagement and a released orientation corresponding to a release of said overlie engagement;
• wherein said overlie engagement is functional to axially retain said control shaft to said axle sleeve and wherein said released orientation is functional to release said overlie engagement and to permit said control shaft to be axially withdrawn and separated from said axle sleeve in said retracting direction.
