Abstract:
An improved vehicle wheel construction having an injection molded generally annular filler ring disposed in a radially inwardly facing circumferential cavity of the wheel to prevent material from accumulating in the circumferential cavity of the wheel and causing an out-of-balance wheel condition and method for producing the same is disclosed. The method includes the steps of (a) providing a rim and a disc; (b) securing the rim and the disc together to produce a wheel construction which defines a radially inwardly facing circumferential cavity; (c) positioning the wheel on a carrier; (d) probing the wheel to make sure the wheel is properly positioned on the carrier in a predetermined position and if not, moving the wheel to the predetermined position; (e) inserting a plug through a valve stem opening formed in the wheel (f) moving a mold into engagement with the inner surface of the wheel adjacent the circumferential cavity, the mold including an outer portion formed of a pliable material and having a profile which generally corresponds to the profile of the adjacent surfaces of the wheel, the pliable outer portion of the mold operative to take up any variations in the wheel profile so as to form a seal at the wheel engagement surfaces and thereby isolate the circumferential cavity; (g) injecting a filler material through a passageway formed in the mold; and (h) maintaining the mold in engagement with the inner surface of the wheel adjacent the circumferential cavity until the filler material cures to a non-reactive state and forms an injection molded generally annular filler ring of a generally solid material.
