A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange;

and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.

A wheel rim including a flange profile on a tire side of an open end flange of the wheel rim, the flange profile defined by the equation: $y_1=(a\mathrm{Theta}1+\frac{1}{{\left(1+\mathrm{Exp}\left(a\mathrm{Theta}3+a\mathrm{Theta}4.Math.X_1\right)\right)}^{\mathrm{aTheta}5}}$

A method for producing a one-piece cast vehicle wheel, the wheel having at least one hub portion connected to a wheel rim via at least one spoke oriented in the radial direction of the wheel, in which at least one lost core is inserted in a molding of the casting machine, the one-piece vehicle wheel is cast, and the lost core is removed from the cast vehicle wheel and thereby forms at least one opening in the spoke. A one-piece cast vehicle wheel formed by the method is also provided.

The present disclosure provides a process for manufacturing a light-alloy hybrid wheel comprising the following separate operation phases: obtaining a front flange with an internal profile including a tire bead seat; obtaining a rim with an annular profile including a tire bead seat at a first end and a circular flank for assembly with a part of the flange at a second end; and assembling the flange and the rim to form a wheel. The annular profiles of the flange and the rim form exterior and interior sides of the wheel. Assembling the flange and the rim comprises welding the flank of the rim and the flange together by a single friction stir weld using a pin such that the weld is exposed at the exterior and interior sides of the wheel.

A wheel disc adapted for use in a fabricated vehicle wheel includes a steel wheel disc defining an axis and includes a center mounting portion, an outer rim connecting flange, a plurality of radially outwardly extending spokes connecting the center mounting portion to the outer rim connecting flange and a ventilation opening provided between each pair of adjacent spokes. A width defined by a center wall of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the center wall of the spoke extends generally from the center mounting portion to the outer rim connecting flange or wherein a width defined by outer walls of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the outer walls of the spoke extends generally from the center mounting portion to the outer rim connecting flange.

A wheel assembly includes a wheel having an outer rim and a hub. A first coupling is applied to the hub. A non-return valve is housed in the first coupling, and a second fitting is applied separably between the hub and the outer rim to connect the outlet of the hub hole with the channel hole.

A method for manufacturing a vehicle wheel of the present invention includes a step of performing an edge treatment including deburring of a spoke edge generated by lathe processing. For the edge treatment, a cutting tool as hale type tool for non-rotational processing is used, and the cutting tool is provided with a processing blade having a recessed blade edge having an R shape or polygonal C shape protruding from an outer peripheral surface on a side of a tip end of the rod-shaped cutting tool connected to a rod-shaped shank portion. A processing machine capable of CNC of four or more axes is used. With the cutting tool standing upright against a disc surface, the blade edge of the processing blade is applied to the spoke edge, and the cutting tool is continuously moved relative to the spoke edge along a ridgeline of the spoke edge for scraping.

An idler wheel includes a hub, an outer rim, and a pair of side plates that form an interior cavity extending radially between the outer rim (110) and the hub, and axially between the pair of side plates. The first side plate defines a maximum side plate axial thickness disposed radially next to the hub in a cross-sectional plane containing a radial direction, and an axis of rotation, as well as a minimum side plate thickness disposed radially next to the outer rim. A ratio of the maximum thickness to the minimum thickness ranges from 1.325 to 1.900.

A method for producing a one-piece cast vehicle wheel, the wheel having at least one hub portion connected to a wheel rim via at least one spoke oriented in the radial direction of the wheel, in which at least one lost core is inserted in a molding of the casting machine, the one-piece vehicle wheel is cast, and the lost core is removed from the cast vehicle wheel and thereby forms at least one opening in the spoke. A one-piece cast vehicle wheel formed by the method is also provided.
