A method for producing an automobile rim from aluminum or an aluminum alloy for a wheel of a motor vehicle. The automobile rim has a rim well delimited on opposite sides by an outer flange and an inner flange, a hub having a center recess and a bolt hole circle, and a rim center connecting the rim well and the hub to one another. The automobile rim is produced integrally and continuously in a casting mold by die casting of a casting material. After the introduction of the casting material into the casting mold, a volume of the casting mold is reduced for post-compaction of the casting material. The invention furthermore relates to a device for producing an automobile rim.

In one aspect of the present disclosure, a wheel hub is provided that includes a wheel hub body having an inboard end and an outboard end. The wheel hub body has a wheel mounting portion, such as a flange, intermediate the inboard and outboard ends. The wheel hub body has a central opening, an interior surface extending about the central opening, and an exterior surface opposite the interior surface. The wheel hub includes a passageway having an interior port at the interior surface of the wheel hub body and an exterior port at the exterior surface of the wheel hub body. The interior port is outboard of the inboard end of the wheel hub body. The exterior port is intermediate the wheel mounting portion and the outboard end of the wheel hub body.

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 hybrid wheel for vehicles that includes a unitary lug structure, with a mount face and a dish section of the lug structure extending therefrom. The lug structure is usually a cast aluminum alloy. A wheel structure including a high strength polymer encapsulates a portion of the lug structure dish section. Rim ring(s) are included in the wheel structure and are preferably made of a fiber reinforced high strength polymer.

A material and method for manufacturing components. The method includes squeeze casting the material into a component of a desired shape and flow-forming the component that has been squeeze cast to refine the shape of the component. The method also includes heat treating the component to enhance the microstructure of the component and machining the component to further refine the shape.

The purpose of the present invention is to minimize decline in endurance, while improving vibration performance. The spokes of an airless tire are provided, as an integrated unit, with an outside annular portion joined to the inside peripheral surface of a tread ring, an inside annular portion joined to the outside peripheral surface of a hub, and a spoke plate portion of constant thickness providing linkage therebetween. The radial inner edge and the radial outer edge of the center plane of thickness of the spoke plate portion are respectively diagonal with respect to a tire axial-direction line. The intersection line at which the center plane of thickness intersects a plane that is at a right angle to the tire axial-direction line constitutes a straight line. The spoke length, which is the length from the radial inner edge to the radial outer edge along the intersection line, is constant for any given location in the tire axial direction.

Disclosed is a hub cleaning device, including a base (1), a mounting transition plate (2), a nozzle adjusting module (3), hub conveying modules (4) and a work fixture (5), in which the nozzle adjusting module (3) is connected onto the mounting transition plate (2), and the mounting transition plate (2) is fixed on the base (1); the work fixture (5) is arranged at a position parallel to the base (1), so that the nozzle adjusting module (3) can face the front side of a hub (6); and the hub conveying modules (4) are arranged on two sides of the work fixture (5). The device is simple in structure, and one device can complete cleaning of multiple types of hubs, thereby greatly reducing the input of enterprises on cleaning devices and saving a lot of money for the enterprises.

A method for producing an automobile rim made of aluminum or an aluminum alloy for a wheel of an automobile, the automobile rim having a rim bed bounded on opposite sides by an outer flange and an inner flange, a hub with a center recess and a bolt circle, as well as a rim center connecting the rim bed and the hub to one another, the rim center being designed with a plurality of spokes spaced apart in the circumferential direction with respect to the longitudinal center axis of the automobile rim. The automobile rim is produced in one piece and continuously in a casting mold by die casting of a casting material, wherein the automobile rim has, at least in some areas, a low wall thickness not exceeding 15 mm.

A cast aluminum wheel includes a rim element having an annular configuration defining an axis and a central element extending radially outwardly between the axis and the rim element. The rim element includes a wall extending circumferentially around the axis between a proximal bead and a distal bead. The central element includes a plurality of spokes extending radially outwardly toward the proximal bead and meets proximate the axis with adjacent of the plurality of spokes defining a cooperative feature therebetween for providing stiffness to the wheel. The spokes progressively increase in volume in a direction toward the axis from the rim element thereby providing increased mass of the spokes proximate the axis relative to the rim element.
