  • Method of forming an axle
    Patent number: 4492019
    Abstract: A method of forming an axle with hollow spindles which 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 steps of forming include providing each of the spindles with an outer cylindrical surface at the region. Air passages are formed in the wall of the spindles communicating the intermediate cavity of the hub with a radially extending passage at the outer cylindrical surface. Each of the spindles is welded respectively to the opposite ends of the central portion of the axle.
