Abstract
The technology provides vehicle wheels that can include a hub coupling portion and a spoke portion. The spoke portion can have a waved portion at a portion of the spoke portion in the radial direction of the wheel and can be decreased in section modulus at a cross section of the portion of the spoke portion 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.
Claims7
A vehicle wheel including a disk press-formed from a plate, the disk comprising:
- a hub coupling portion;
- a plurality of spoke portions each extending outwardly in a radial direction of a wheel from the hub coupling portion;
- a vent window located between adjacent spoke portions of the plurality of spoke portions;
- and
- a radially outer disk portion located at a radially outer end portion of the wheel and connecting radially outer end portions of the adjacent spoke portions of the plurality of spoke portions along a circumferential direction of the wheel,
- wherein each of the plurality of spoke portions includes a spoke bottom wall having a width extending along the circumferential direction of the wheel and a pair of spoke side walls rising from opposite circumferential ends of the spoke bottom wall in an axial direction of the wheel,
- wherein each of the plurality of spoke portions is located outside the hub coupling portion and the radially outer disk portion in the axial direction of the wheel, and
- wherein each of the plurality of spoke portions includes a waved portion located at only a portion of each of the plurality of spoke portions in the radial direction of the wheel, the waved portion extending in a direction perpendicular to the radial direction of the wheel at each of the plurality of spoke portions and decreasing a bending rigidity of each of the plurality of spoke portions in the radial direction of the wheel by decreasing a rising amount of the pair of spoke side walls.
