A vehicle wheel rim is printed with a metal alloy by a three-dimensional printing method. The rim includes a substantially circular rolling strip defined by a front edge and a rear edge. The rolling strip includes a central rim base, a front part including fittings for a front tire support, located between the rim base and the front edge, and a rear part including fittings for a rear tire support, located between the rim base and the rear edge. The rim is designed to be mounted on a vehicle such that the front edge is located on an outer side of the vehicle and the rear edge is located on an inner side of the vehicle. The rolling strip includes a plurality of cavities in the thickness thereof and in a radial section.

Provided is a vehicle wheel capable of improving sound deadening property by increasing a capacity of an auxiliary air chamber member without impairing an assembling property of a tire. An upper surface portion of a width-direction cross-section of an auxiliary air chamber member includes a first side wall portion and a second side wall portion which extend radially outwardly. The upper surface portion further includes a curved portion having a convex shape. The curved portion is connected to the first side wall portion and the second side wall portion at connection points. As a result, the curved portion is configured to have a convex shape projecting outwardly in a radial direction.

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.

Disclosed is an aluminum wheel for a vehicle, in which a resonance tube is coupled to a rim of the wheel, wherein a first surface of the resonance tube is fitted into a well groove formed in a well of the rim, and a second surface of the resonance tube comes into contact with the rim by a pressure member including a steel wire and a fixing member.

A preform for fabricating a wheel rim and a method of making a preform is provided. The preform includes a main section and at least one secondary section, each section being formed from composite materials, such as triaxially braided composite material that includes fibers oriented in at least three directions. The main section forms at least part of a lateral section of the preform and the secondary section forms at least part of a radial portion of the preform, the radial portion of the preform being generally perpendicular to the lateral section of the preform. The preform is fabricated from a plurality of composite layers, at least some being custom composite layers having a plurality of axial fibers interwoven intermittently with substantially consistent first and second sets of biased fibers. In some embodiments, the preform is initially fabricated in an intermediate configuration prior to being moved to a final configuration.

A wheel assembly includes a central hub, an outer rim including a spoke bed wall, and a spoke unit including first and second spokes. Each of the first and second spokes extends between the outer rim and the central hub, and has a first end connected to the spoke bed wall, a second end opposite to the first end and connected to the central hub and a span portion connected between the first and second ends. The first ends of the first and second spokes are respectively formed with first and second spoke bed connection portions where the first and second spokes are respectively connected to the spoke bed wall. With respect to the central hub, the second spoke bed connection portion is radially outboard relative to and circumferentially spaced from the first spoke bed connection portion.

The present invention provides a vehicle wheel configured to assemble a motor having an uneven weight distribution. The vehicle wheel comprising a rim having an asymmetric structure. The rim comprising a drop center (202) for mounting a tire, side sections (204A-D) extending axially outward from both sides of the drop center (202), bead bases (208A-D) extending axially outwards from said side sections (204A-D), and flanges (210A-D) disposed axially outward of said bead bases. The bead bases having non symmetrical lengths to compensate the uneven weight distribution of said motor on the rim. The drop center having a drop diameter that is compatible with the diameter of the motor for inserting and encapsulating said motor therein, and the asymmetric structure of the rim compensates the uneven weight distribution of said motor on the rim, thus, maintains said wheel balanced with a minimal overall offset from the center line of the rim.

The invention relates to a bicycle wheel made of a fiber composite material, including a rim, a plurality of spokes, and a center, wherein the spokes each have a first and second spoke section extending between the rim and the center, wherein the first and second rim section have a curved shape in a laminated state and the two rim sections extend straight in a pretensioned state.

A preform for fabricating a wheel rim and a method of making a preform is provided. The preform includes a main section and at least one secondary section, each section being formed from composite materials, such as triaxially braided composite material that includes fibers oriented in at least three directions. The main section forms at least part of a lateral section of the preform and the secondary section forms at least part of a radial portion of the preform, the radial portion of the preform being generally perpendicular to the lateral section of the preform. The preform is fabricated from a plurality of composite layers, at least some being custom composite layers having a plurality of axial fibers interwoven intermittently with substantially consistent first and second sets of biased fibers. In some embodiments, the preform is initially fabricated in an intermediate configuration prior to being moved to a final configuration.

A rim for a bicycle wheel includes a radially outer tire-engaging portion, a first sidewall, and a second sidewall spaced apart from the first sidewall. The first and second sidewalls may extend radially inward of the radially outer tire-engaging portion. The rim includes a radially inner portion having at least one asymmetric protrusion.
