Abstract

A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange; and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.

First claim

What is claimed is:

1 . A vehicle wheel comprising:
a rim and a disc which are molded in a one-piece body; a resonance chamber defined at a boundary between the rim and the disc; a forming end configured to enclose the resonance chamber; and a sound-absorbing hole defined in the forming end such that the resonance chamber and an interior space of a tire communicate with each other through the sound-absorbing hole, wherein a hollow insert neck having an inner diameter and a length adjustable according to a target resonance frequency is tightly disposed in the sound-absorbing hole.

2 . The vehicle wheel of claim 1 , wherein the insert neck has a straight tube shape.

3 . The vehicle wheel of claim 1 , wherein the insert neck has a tapered tube shape.

4 . The vehicle wheel of claim 1 , wherein the insert neck includes a first uneven part on a circumferential portion thereof and the sound-absorbing hole includes a second uneven part on an inner diameter portion thereof such that the first uneven part and the second uneven part are engaged and locked to each other.

5 . The vehicle wheel of claim 1 , wherein the insert neck includes a male screw part on a circumferential portion thereof and the sound-absorbing hole includes a female screw part on an inner diameter portion thereof such that the male screw part is screw-fastened to the female screw part.

6 . A vehicle wheel comprising:
a rim and a disc which are separately molded to be coupled to each other; a resonance chamber defined at a boundary between the rim and the disc; a forming end configured to enclose the resonance chamber; and a sound-absorbing hole defined in the forming end such that the resonance chamber and an interior space of a tire communicate with each other through the sound-absorbing hole, wherein a hollow insert neck having an inner diameter and a length adjustable according to a target resonance frequency is tightly disposed in the sound-absorbing hole.
