  • Patent number: 9302534
    Abstract: Each spoke portion (50) includes a center valley portion (51), and spoke projecting threads (52) formed on both sides of the center valley portion (51). Each of the spoke projecting threads (52) includes an inclined surface portion (54), which protrudes outward in a spoke widthwise direction from a top (53) and inclines downward to a wheel axially back side. The inclined surface portion (54) is formed so that a length thereof in a range of from the top (53) to an outer end of the inclined surface portion (54) in the spoke widthwise direction becomes larger toward a spoke distal end side, and that an average downward inclination angle thereof becomes smaller toward the spoke distal end side. With this configuration, it is possible to increase rigidity of the spoke portion with good balance while avoiding interference with a braking device.

  • Publication number: 20110227400
    Abstract: The invention relates to a wheel rim for a motor vehicle which can be economically manufactured, with a wheel disc made of steel sheet and a rim flap running around the circumference of the wheel disc. Due to the fact that the steel sheet of the wheel disc is formed from at least three superimposed steel layers, joined to one another by roll-bonding in a non-detachable manner, of which the inner core layer has a lower strength than the outer layers it is thereby guaranteed that the wheel rim according to the invention, with a low weight, can safely accommodate the forces arising in practical operation.

    Abstract: An outer rim molded material is molded by forging or casting, a portion of the outer rim which extends from a hump to a bead seat is separated from part of a rim flange precursor and is caused to fall in a sloping fashion inwards of a wheel width so as to form a bead seat precursor, and the bead seat precursor so formed is then joined to be welded to a top or side of a rim well rising portion precursor. An external surface is cut to be finished to a proper shape, and an annular hollow portion is formed underneath a lower surface of the bead seat portion.

  • Publication number: 20110140506
    Abstract: The invention relates to a vehicle hybrid wheel comprising a formed steel rim ring and a wheel disk, manufactured as a light-alloy casting having a concentrically formed disk edge, on which the rim ring bears at least partially at multiple, spaced contact points for rotationally fixed connection to the wheel disk. In order to ensure an adequate force flux between the rim ring and the wheel disk, the wheel disk is provided with a circumferentially formed depression, in which a circumferential edge of the rim ring, angled radially outwards in relation to a bead seat section formed on the rim ring, engages by positive interlock and/or force closure.

  • Publication number: 20110101769
    Abstract: A wheel hub includes a wheel rim and a support. The wheel rim has an inner rim surface, an outer rim surface and a connection concave. The wheel rim is composed of a metallic layer and a carbon fiber layer. The outer rim surface has an outer wall to be the metallic layer. The wheel hub is composed of the metallic layer and the carbon fiber layer. Compared to the conventional wheel hub made of a single metallic material or a carbon fiber material, the wheel hub made of metal and carbon fiber of the present invention is light in weight, endurable, and cost-effective. The outer wall of the outer rim surface of the conventional wheel hub is easily to be damaged by an external force when in use, which result in a break of the carbon fiber to lose the strength of the carbon fiber.

  • Patent number: 7703859
    Abstract: Disclosed are various embodiments of one-piece, and multi-piece wheels configured to provide increased interior lip depth. In one embodiment, an outer periphery of a curved center portion of a wheel is attached to a wheel barrel in an inboard region, and a portion of the center portion extends into the outboard region of the wheel. At least a portion of the wall of the wheel barrel preferably comprises a gradual slope, instead of a traditional wheel mounting drop, and thus the interior lip depth is not obstructed by the interior bulge generally created by such a drop. In other embodiments, a wheel mounting drop is configured to permit multi-piece wheels to be joined at or near one of the drop walls to allow the wheel center to be positioned further in the inboard direction than in traditional wheels.
