The present application relates to an ultra-lightweight steel wheel for a commercial vehicle. The wheel has excellent material characteristics and an advanced design, and consists of a rim for mounting a tire, and a disc having a hub flange for detachably connecting to a wheel hub or axle, wherein the rim and/or disc is made of a heat-treated and hardened steel material with a carbon content between 0.18 wt % and 0.37 wt %, and the disc and/or rim principally consists of a martensitic microstructure and has a tensile strength of at least 900 MPa. The maximum thickness of the rim is less than 4.50 mm and/or the maximum thickness of the disc is less than 12.00 mm, wherein the value of the product of the wheel diameter and the wheel width divided by the wheel mass is greater than 4000 mm.sup.2/kg.

A spoke for use in connection with a wheel, the spoke having a braided fiber having a first end and a second end, a rod having a first end and a second end, whereby the first end of the rod is threaded and wherein the second end of the rod is disposed inside the first end of the braided fiber.

The present disclosure relates generally to devices and methods which use the mechanical advantage of a lever and fulcrum along with the use of force from a user's body, foot, and leg muscles, to more ergonomically and safely install wheel assemblies on vehicles while keeping the user's back at a more ergonomic angle and allowing for both of the installer's hands to remain free for stabilizing the wheel assembly during installation. The lifting device provides a foot pedal, a lifting pad and a pivot point to position a wheel assembly on a hub and/or wheel studs.

A bicycle hub assembly comprises a hub axle, a hub body, a sprocket support body, and a freewheel structure. The sprocket support body includes at least ten external spline teeth configured to engage with a bicycle rear sprocket assembly. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface. The freewheel structure includes a first ratchet member and a second ratchet member. The first ratchet member includes at least one first ratchet tooth. The second ratchet member includes at least one second ratchet tooth configured to engage with the at least one first ratchet tooth in a torque transmitting manner.

A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.

A motorcycle wheel is provided, in particular a motorcycle wheel suitable for use on an enduro motorcycle. The wheel includes a cast or forged rim having integrally spokes which extend toward a central hub connection region. The central hub connection region is configured to receive a hub element in a detachably fastened manner. The hub element forms a hub of the motorcycle wheel which is connectable to a motorcycle.

The present invention relates to a wheel comprising a hub formed inside the wheel, a rim portion separated outwardly from the hub and forming a circumference on which a tire is fitted, a plurality of spokes connecting the hub and the rim portion, wherein the rim portion is characterized by 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 equispaced 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 job 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.

Forward movement of a bicycle results when force is transfer from the chain or belt to a sprocket on a cassette. The cassette is splined to the cassette driver and causes the wheel of the bike to rotate when torque is applied from the cassette to the cassette driver. The cassette driver is typically made of a strong hard material such as steel to withstand the forces in parted thereon by the cassette. The present disclosure provide a hub configuration and method that enables the cassette driver to be made with construction of a lighter weight material such as aluminum yet still withstand the toque applied thereto.

A wheel assembly including a cover portion permanently attached to a wheel. The wheel includes a wheel central hub portion, a wheel outer peripheral rim portion, a plurality of wheel spoke portions extending between the wheel central hub portion and the wheel outer peripheral rim portion, and a plurality of wheel turbine openings disposed between adjacent ones of the plurality of wheel spoke portions. A cover portion is configured to overlie a portion of the wheel portion. The cover portion is configured to overlie one or more of the wheel central hub portion; the plurality of wheel spoke portions, and the plurality of turbine openings or the wheel outer periphery. An adhesive is disposed between an outboard surface of the wheel and the inboard surface of the cover portion to permanently secure the cover portion to the wheel portion. When the cover portion is secured to the wheel, substantial portions of the plurality of wheel spokes, the wheel central hub, or wheel outer periphery remain exposed.
