Abstract
PURPOSE: To obtain the captioned rim which is increased of radial load durable life and makes possible the reduction in weight by working an Al alloy substrate for roll stretching in which the thicknesses of the portions corresponding to the radii of bead seat parts and well parts are partially increased to ring form then forming the same.
CONSTITUTION: The thicknesses of the portions 8, 8', 9, 9' corresponding respectively to the radial parts 2, 2' at both ends of the well parts of the rim outside circumference of an Al substrate 7 for roll stretching to be formed to a rim for disc wheels and the radial parts 5, 5' at one end of the bead sheet parts are beforehand increased and this substrate 7 is worked to the ring form which is similar with conventional methods. After its both ends are bonded by welding or the like, it is roll- formed to produce the rim for disc wheels. This method considerably improves the radial load durable life as a wheel, makes possible the reduction in weight of the aluminum-alloy-made rim for disc wheels of automobiles and is effective for saving of fuel cost.
