The application relates to a wheel hub for vehicle, which comprises a flange, a rim, a spoke, a central hole, and bolt bores distributed around the central hole. According to the disclosure, the flange on the wheel front side is affixed with an extension part comprising a radial extension magnitude extending to the outer periphery of the wheel hub and an axial extension magnitude extending to the wheel front side, the extension part comprises a plurality of sections circumferentially distributed along the flange, so as to form on the wheel front side an envelope circle having a diameter size increased by twice the radial extension magnitude. The present disclosure further satisfies the additional needs of the user with respect to the overall design of the wheel.

In one aspect of the present disclosure, a vehicle wheel is disclosed that includes a cover and a backbone. The cover includes recessed portions and non-recessed portions defining inner surfaces that are spaced about a periphery of the cover, and the backbone defines at least one first support that is configured and positioned for contact with the inner surfaces defined by the recessed portions and at least one second support that is configured and positioned for contact with the inner surfaces defined by the non-recessed portions.

The vehicle wheel rim with integral spare tire includes a main wheel and an integral spare tire. The main wheel includes a main rim well, an inner and outer flange, and a center disc. A main tire may be mounted onto the main wheel and the main wheel may be bolted onto a hub on an axle of a vehicle. The integral spare tire includes a safety rim well, safely rim, and safety tire with the safety tire mounted on the safety rim. The integral spare tire is coupled to the inside of the main wheel. The dimensions of the main wheel, main tire, and integral spare tire are such that when the main tire is inflated the integral spare tire does not touch the road surface. However if the main tire goes flat the integral spare tire will touch the road surface and will support the vehicle.

A structure of a bicycle wheel rim is disclosed. It comprises an inner rim frame and a composite rim body. The inner rim frame is provided with an inner rim part, two lateral ring parts respectively disposed on both sides of the inner rim part, two hooks respectively disposed on terminals of the two lateral ring parts, and an opening formed between the two hooks and having a supporting part. The composite rim body encapsulates the inner rim part, the two lateral rings and the two hooks.

An integrally formed wheel for cooling a brake assembly of a vehicle, comprising a barrel for mounting a tire thereon, a center disc, and a plurality of spokes. The barrel extends from an outboard face to an inboard rim edge and defines a chamber radially inside the barrel. The chamber is located adjacent a brake mechanism when the wheel is on a vehicle. The center disc has a center bore and a plurality of lug holes. A plurality of spokes interconnects the center disc to the barrel. A plurality of cooling passageways is integrally formed with the barrel, the spokes and the center disc. The plurality of passageways is disposed circumferentially around the spokes and extend from the outboard face to a location inside the barrel to direct air into the chamber through the passageways when the wheel is in rotation.

A rim with an inner flange having strip weight reduction sockets and a wheel are provided. The rim includes the inner flange, a middle portion and an outer flange which are all annular and are connected end to end to form an annular rim, in which trapezoidal weight reduction sockets are provided on the inner wall of the inner flange; the bottom edges of the weight reduction sockets are flush with the edge of the inner flange; the top edge of each weight reduction socket has fillets; and the weight reduction sockets have a bottom edge length of 5-30 mm, a height of 15-60 mm, a top edge length of 5-15 mm, a base angle of 72-83, and a depth of 1-5 mm.

A spoke wheel comprises a rim for supporting a tire having rim guards, a hub located radially inwardly with respect to the rim, and a plurality of spokes integrally connected with the rim and the hub at outer and inner ends, respectively, and extending radially with respect to the hub. The laterally outer surface of the outer end of each spoke and the laterally outer peripheral edge of the rim are located laterally inwardly with respect to the tip of the laterally outer rim guard. Outer ends of main spokes of the spokes are provided with convex portions projecting laterally outwardly and extending in the radial direction, and a lateral position of the laterally outer tip of each convex portion lies in the range between a lateral position of the laterally outer peripheral edge of the rim and a lateral position of the tip of the rim guard.

Road tubeless rims may include a pair of circumferential flanges having inner tire seating surfaces that are nonconcave and angled toward the centerline. Tubeless tires mounted to the illustrative rims may achieve improved sealing performance due to an increased seating area of the rims. A shape and angle of the flanges may shape the tire to achieve an aerodynamic wheel profile.

A bicycle rim may control the two beads of the tire with separate bead channels for each bead and a center bridge extending between the two bead channels. A bicycle assembly comprises a bicycle rim having an attachable annular strip formed separately from the bicycle rim and attached to the bicycle rim along a center line of the center channel. The annular strip comprises a set of strip sidewalls and a center section extending between the strip sidewalls, wherein the strip sidewalls are spaced at less than the channel width such that the strip forms a pair of bead channels in cooperation with the channel first outer sidewall and channel second outer sidewall.
