Abstract: A vehicle wheel having a rim and a disk. A disk flange of the disk may have a non-contact portion non-contacting a radially inner surface of the rim, at a radially outer extension of a width center line of a spoke. As a result, the rigidity of a portion of the disk in the circumferential direction of the wheel where the spoke is provided may be decreased compared with a wheel (conventional) where such non-contact portion is not provided. A difference in rigidity of the disk in the circumferential direction of the wheel between a portion where the vent window is provided and a portion where the spoke is provided may be smaller than that in the case of the conventional wheel, whereby a durability of the wheel and a run-out accuracy of the wheel may be improved.

Abstract: The technology provides vehicle wheels that can include a hub coupling portion and a spoke. The spoke can have a waved portion at a portion of the spoke in the radial direction of the wheel and can be decreased in section modulus at a cross section of the portion of the spoke taken along a plane perpendicular to the radial direction of the wheel. The waved portion can be formed by displacing the spoke bottom wall and/or the spoke reinforcing walls in the axial direction of the wheel.

Abstract: A vehicle wheel disk includes a plurality of spoke portions extending radially outwardly from a hub coupling portion with vent windows between the spokes. Each spoke includes a bottom wall and axially extending side walls, with a radially outer disk portion connecting the radially outer ends of the spokes. A connecting wall connects a pair of spoke side portions on opposite sides of the vent window in the circumferential direction of the wheel. The spoke bottom wall includes an axially extending inclined portion and a radially extending main portion. A spoke strengthening wall extends circumferentially from the axial end of the spoke side wall. The connecting wall includes a vent window surrounding portion, a vent window surrounding curved portion, and a crest wall portion of a radially inwardly protruding protrusion.

Abstract: A wheel for vehicle comprising: a rim 2 having a drop portion; and a disk 10 formed integrally from a plate material, the rim and the disk being welded together, wherein the disk has: a hub mounting portion 10a; a plurality of spokes 10b radially extending from the hub mounting portion toward an outer periphery of the disk; and a ring-shaped disk flange 10c that is connected to the spokes through a curved-surface connecting portion R that is formed by bending the spokes at an outer circumferential end thereof in a wheel axial direction, the disk flange extends in the wheel axial direction, and a decorative hole 20 is defined by the adjacent spokes, the hub mounting portion, and the disk flange, and a part that faces a distal end 12 of the spoke in a fitting area between an inner circumferential surface of the rim and an outer circumferential surface of the disk flange is welded.

Abstract: The technology provides vehicle wheel disks where a spoke portion can have a spoke bottom wall and a spoke side portion. The spoke side portion can include a spoke side wall rising from the spoke bottom wall in an axial direction of the wheel and a spoke reinforcing wall connected from an axially end portion of the spoke side wall and curved from the axial direction of the wheel toward a circumferential direction of the wheel and extending in the circumferential direction of the wheel. A pair of spoke side portions can be located on opposite sides of the vent window in the circumferential direction of the wheel have radially inner end portions which are connected to each other via a connecting wall. The connecting wall can be flat or substantially flat in the circumferential direction of the wheel.

Abstract: A method comprising: a step of preforming a plurality of bulging portions on a substantially circular plate blank, the bulging portions being located concentrically and circumferentially outward of a bolt hole, each of the bulging portions being a base of a reinforcing portion of a spoke; a step of forming a plurality of prototypical decorative holes on the respective bulging portions to form a prototypically-shaped spoke between the adjacent prototypical decorative holes; a step of forming a disk flange by bending an outer circumferential portion of the plate blank, on which the prototypical decorative holes are formed, at a right angle to be substantially parallel to a wheel axial direction, so that an outer periphery of a resultant decorative hole forms an upper end edge of the disk flange; and a step of forming the spoke by providing the prototypically-shaped spoke with the reinforcing portion.
