  • Automobile wheel and process for producing the same
    Patent number: 8123303
    Abstract: In an automobile wheel, a surface-side flange is provided on an outer circumferential edge of a wheel disk. The surface-side flange includes: a surface-side annular circumferential portion on an aesthetic surface; and a back-side annular circumferential portion that is formed continuously with, and on the back side of, the surface-side annular circumferential portion and that is thinner than the surface-side annular circumferential portion. An inner circumferential end of the back-side annular circumferential portion of the surface-side flange and an opening end of a surface-side bead seat of a wheel rim are welded together all along their circumferences. The automobile wheel allows the back-side annular circumferential portion of the surface-side flange to bear a stress that acts on a weld area. This relaxes the stress concentration on the weld area.

  • AUTOMOBILE WHEEL
    Publication number: 20100314932
    Abstract: In a disc of an automobile wheel, a plurality of hub surface rounded portions are formed at intervals on an imaginary circle provided around a hub hole and centered on an imaginary center corresponding to the center of the hub hole. The hub surface rounded portions are provided with a compressive residual stress by a compression process for work hardening. The strength of the hub surface rounded portions can thus be improved.
