Equipment including a rigid plate provided with a plurality of cutters configured to be impressed in sequence against a swaged annular collar of an inner ring of a wheel hub, the collar being formed with a first radial profile; the cutters sliding axially through the plate and towards a first face of the plate resting in abutment against the collar; wherein the first face of the plate is provided in the region of the cutters with a concave annular seat having a second radial profile configured to copy at least partly the first radial profile of the collar, the annular seat being configured to be passed through by the cutters during the step for impression against the collar and to contain any radial flow of the metallic material which forms the collar.

The omnidirectional wheel includes a first support portion which rotates around a rotation axis line, a second support portion which rotates together with the first plate-like member, a number of support shafts respectively supporting a number of rollers, and a number of support plates fixed to the first and the second support portions and which support one or more of the support shafts between the first and second support portions.

A fabricated vehicle wheel comprises a wheel disc and a wheel rim. The wheel disc has an annular hub portion, a center hub hole in the hub portion, opposite inboard and outboard faces of the hub portion, a plurality of circumferentially spaced lug bolt holes in the hub portion, a plurality of lightener pockets in the hub portion, and an extension portion. The lug bolt holes and the lightener pockets alternate around a circumference of the hub portion. An axis extends through the hub hole. The inboard face is planar and configured to mount to a vehicle. The inboard face is perpendicular to the axis and the extension portion extends from the hub portion along the axis. The wheel rim is secured to the extension portion.

A manufacturing method for a wheel disc, includes forming a flange portion, wherein the flange portion is formed such that an inner mold and an outer mold having a cylindrical inner surface with a first inside radius larger than the first outside radius and placed above the inner mold coaxially to the inner mold are brought close relative to each other in an axial direction by one stroke so that the outer edge of the disc material is bent downward, and the cylindrical inner surface of the outer mold is provided with recessed portions hollowed outwardly in a wheel radial direction, the recessed portions being formed in ranges corresponding to the window portions in the wheel circumferential direction and in a range from a middle position to a bottom end in the wheel axial direction.

Wheels for use on vehicles and methods of manufacturing vehicle wheels are described in the present disclosure. According to one embodiment, a method includes a step of manufacturing a wheel that includes a rim, a center disk, and a plurality of spokes. The rim may include a substantially-cylindrical barrel adapted to seal a tubeless tire. The center disk may include a central bore adapted for engagement with an axle of a vehicle. Also, the plurality of spokes may be adapted to connect the center disk to the rim. The method further includes the step of deforming outwardly-facing surfaces of the spokes using one or more hammering or punching instruments.

Vehicle wheel comprising a rim part and a disc part formed from a one-piece sheet metal blank and including a central portion with bolt holes and a plurality of radially extending spoke arrangements merging into a disc edge delimiting together with the spoke arrangements ventilation apertures which extend over the region between the edge webs and the disc edge. In order to create steel wheels with four-hole fixing in which high strength and stiffness are achieved the number of spoke arrangements and of bolt holes is four and these are in each case arranged mirror-symmetrically with respect to a common radial line, with the width of each spoke arrangement narrowing radially towards the outside and each ventilation aperture extending in the circumferential direction over an arc length of more than of the circumference of the disc part. Further, each ventilation aperture is having on a radial line a maximum radial clear width which is equal to or preferably greater than the radial width of the metal portion of the disc part on the same radial line.

The omnidirectional wheel includes a first support portion which rotates around a rotation axis line, a second support portion which rotates together with the first plate-like member, a number of support shafts respectively supporting a number of rollers, and a number of support plates fixed to the first and the second support portions and which support one or more of the support shafts between the first and second support portions.
