The present invention relates to a hubless one-piece wheel comprising: a rim; and a disc integrally formed at the rim and formed by low-pressure casting, wherein the disc is a hubless type including a plurality of spokes and a space at the center of the rim. One side of said each spoke is integrally formed at the rim, and a lug hole is formed in the other side of said each spoke for coupling the wheel to a vehicle body. The plurality of spokes are radially arranged inside the rim, and each of the other sides of the spoke locates in the inner center portion of the rim being separated by the space.

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.

A vehicular wheel assembly defines an axis of rotation and includes a wheel having an inner hub, an outer rim, and a plurality of hollow spokes. The outer rim defines an outer circumference. Each hollow spoke of the plurality of hollow spokes extends between the inner hub and the outer rim and includes a wall that at least partially defines a hollow chamber. The outer rim defines a plurality of openings that are each in fluid communication with one of the hollow chambers and each of the openings includes a tuning member.

The disclosure provides a process for casting aluminum alloy parts. The process comprises the steps as follows: raising liquid; filling mold; increasing pressure; solidifying consisted of at least two stages of different pressure settings; and relieving pressure.

A method and system for improving the strength, functionality and wear-resistance of a composite hybrid wheel is disclosed. Each spoke may define an airfoil shape and have a secondary wing-like extension attached thereto to generate airflow past the vehicle brakes during vehicle operation. Alternatively, the spokes may be shaped in cross-section as either an I-beam or an H-beam configuration. Customer-interchangeable wheel inserts formed from a reinforced polymerized material, such as a long carbon fiber reinforced composite, are strategically attached to one or more of the spokes. The inserts are used to enhance the aesthetic appeal of the wheel, increase its structural integrity and provide easy interchangeability in the event of damage. A faux bead composite lock ring also formed of a reinforced polymerized material such as a long carbon fiber reinforced composite can be attached to the wheel spokes to cover the composite rim flange.

A disc portion and a rim portion of a tire wheel are integrally formed simultaneously, with a resonance pipe formed between the disc and rim portions, by inserting a molten metal into a space formed by a mold combined with the resonance pipe by core pins.

The present invention relates to a wheel having a rim portion including an air-tight rim formed in a cylindrical shape, and a protruded grid portion having a plurality of first recesses by being protruded from and equally spaced around the circumference of the air-tight rim. In this way, the honeycomb rim-type wheel can be readily manufactured to have lightweight using a single casting without sacrificing durability thanks to the protruded grid portion on the circumference of the air-tight rim, thereby reducing time and cost for manufacturing by reduced usage of molten metal.

A casting system includes a casting for an automobile vehicle having an interior section. Multiple central portions are individually positioned in one of multiple areas of the interior section completely encapsulated by a metal of the casting. An insert member is positioned in individual ones of the multiple central portions, the insert member having a higher melting point than a melting point of a metal of the casting the insert member displaces.
