Abstract: An axial clamping system for securing a wheel assembly onto a tire changer drive spindle. The clamping system consists of a shaft for engaging an axial bore of the drive spindle, configured with a set of ball bearings seated within radial bore arranged in a spiral configuration and which extend into a central bore of the shaft. Axial movement of a plunger within the central bore radially displaces the ball bearings to protrude outboard of the shaft outer surface, engaging a spiral channel within the drive spindle axial bore. Rotation of the clamping system within the drive spindle axial bore while the ball bearings engage the spiral channels, tightens a clamp nut against a wheel assembly seated on a flange of the drive spindle. Counter rotation and retraction of the plunger within the shaft releases the clamping forces, allowing for removal of the wheel assembly from the drive spindle.
