An axle is made-up of a left and a right axle halves which axially engage to form a completed axle assemble for supporting a roller skate wheel or other rotating member. A control rod is positioned and enabled for axial translation within the axle and may be moved by physical contact with the rod through an access hole at one end of the axle. A spring normally positions the control rod so that a set of ball bearings mounted within radial holes in the axle are forced into outward positions for engaging the axle halves to form a unitary unit. When the control rod is translated against spring tension, however, the bearings are able to move radially inwardly so as to disengage the axle halves for quick disassembly for replacing a wheel or other need. The axle provides a spring bias enabled for forcefully separating the axle halves once released. A threaded cap is adjustable in its position to moderate the separating force.

[ What is claimed is:] [1.]1. A control-rod actuated axle apparatus comprises a pair of cylindrical axle portions with one of the axle portions adapted for receiving the other of the axle portions for mutual engagement in unitary axial alignment, thereby imparting a first potential energy to a first biasing means within the one of the axle portions; and a control rod engaged within the other of the axle portions and positioned by a second biasing means for forcing at least one locking elements into positions for locking the pair of axle portions; the control rod axially movable for positioning a reduced diameter portion of the control rod for enabling the locking elements to unlock the axle portions for separation thereof, the first biasing means forcing the axle portions apart by releasing the first potential energy thereof; further comprising a retaining means engaged within the other of the axle portions for retaining the second biasing means therewithin; wherein the retaining means is a retaining ring of a spring temper material, removably fitted into a circular retaining slot within the other of the axle portions.
