Vehicle wheel and method for manufacturing vehicle wheel |
摘要 |
A vehicle wheel according to the present invention includes a hollow-state hollow portion and a solid-state non-hollow portion inside an outboard bead seat in a radial direction, which are provided in series in a circumferential direction of the wheel, the non-hollow portion having a cross section with a larger area than a hole cross section of a valve hole and having the valve hole formed therein. This structure prevents a sealing structure for ensuring hermetic performance from being complicated as compared to a wheel having the valve hole in the hollow portion, thus simplifying a mounting structure of an air valve. A method for manufacturing such a vehicle wheel allows formation of the valve hole in the non-hollow portion. Machining dust generated through a cutting process can thus be prevented from entering the hollow portion and remaining therein. |

1. A method for manufacturing a vehicle wheel having a rim including outboard and inboard bead seats for supporting a bead of a tire and a valve hole provided inside in a radial direction of the outboard bead seat for mounting an air valve, the method comprising the steps of:
forming an annular vertical wall which protrudes outward in the radial direction from an outer surface of the rim throughout the whole circumference, and forming a protruding portion which protrudes outward in the radial direction from the outer surface of the rim and has a larger cross section than a hole cross section of the valve hole and a recessed portion which has a smaller outer diameter than the protruding portion between an outboard flange and the vertical wall in series in a circumferential direction of the wheel; forming the outboard bead seat configured with a bent vertical wall formed by bending the vertical wall toward the outboard flange and joining an end portion of the vertical wall to the outboard flange throughout a whole circumference, a hollow-state hollow portion configured with the bent vertical wall and the recessed portion, and a solid-state non-hollow portion configured with the protruding portion; and forming the valve hole in the non-hollow portion by a cutting process, the steps being sequentially conducted. |
