Abstract
An axle includes a central portion with a pair of hollow spindles welded thereon which spindles are each capable of supporting a rotatable hub having a wheel and tire mounted thereon. Each hub would include an intermediate cavity which is sealed to define with a wall of the spindle a reservoir for inflation air for the tire. Inflation air is supplied to the spindle at a region axially inwardly of the hub at a predetermined circumferential location thereon. The spindles include an outer cylindrical surface at the region. Air passages formed in the wall of the spindles communicate the intermediate cavity of the hub with a radially extending passage at the outer cylindrical surface. A pair of collar elements each have an inner cylindrical surface matching the outer cylindrical surface of the spindle and a coupling passage and fitting for mating with the supply of inflation air. Each of the collar elements is respectively mounted on the outer cylindrical surface of each of the spindles with the radially extending passage and the coupling passage connected by a circumferential groove in either the outer or inner cylindrical surface and the fitting positioned at the predetermined circumferential location for mating with the supply of inflation air.
