Publication number: 20150042150Abstract: Each spoke portion includes spoke projecting threads on both sides thereof, and a reinforcing plate portion is formed so as to protrude from a side edge of each of the spoke projecting threads outward in a spoke widthwise direction. The reinforcing plate portion is formed continuously with an inter-spoke plate potion extended from a fitting portion of a disc flange portion to a wheel radially inner side, and forms an integral plate surface with the inter-spoke plate portion. With this configuration, it is possible to reduce imbalance of rigidity of the spoke portion in a radial direction, and to increase rigidity of an automobile wheel.Type: ApplicationFiled: April 24, 2012Publication date: February 12, 2015Applicant: CENTRAL MOTOR WHEEL CO., LTD.Inventor: Yoshifumi Goto

Patent number: 7464995Abstract: According to the invention, the fabricated vehicle wheel includes a conventional full wheel rim and a unique wheel disc joined to the wheel rim. The wheel disc includes an inner wheel mounting pad, an outer annular rim connecting flange and a plurality of radial spokes connecting the inner wheel mounting pad to the rim connecting flange. The rim connecting flange extends in an axial direction and defines a side edge surface extending between each pair of adjacent spokes. A plurality of windows are formed in the wheel disc. Each of the windows has a predetermined shape defined by the adjacent spokes and the side edge surface of the rim connecting flange. The rim connecting flange and the side edge surface are configured such that the window extends to an outermost periphery of the wheel disc. The inner wheel mounting pad includes at least one rib provided therein. The rib has an outer surface and an inner surface, at least one of the outer surface and the inner surface is provided with a flat planar surface.Type: GrantFiled: June 13, 2006Date of Patent: December 16, 2008Assignee: Hayes Lemmerz International, Inc.Inventors: Montgomery D.
