The invention relates to a wheel rim for a vehicle wheel with cover elements.

A wheel structure for a vehicle includes: a rim, and a resonator including a plurality of resonance tubes attached along an outer peripheral surface of the rim. The plurality of resonance tubes are spaced apart from each other and connected along the outer peripheral surface of the rim by a plurality of strips, and an end of each of the strips is coupled to a corresponding end of each of the resonance tubes.

A wheel rim structure includes an integral frame body. The frame body has two side walls, a bottom wall, and a connecting rib. The bottom wall is integrally connected between bottom edges of the two side walls. The connecting rib is integrally connected between the two side walls and has a predetermined distance from the bottom wall. Inner wall surfaces of the side walls, the bottom wall and the connecting rib are formed with a plurality of crests arranged at intervals and a plurality of troughs each connected between every adjacent two of the crests. Outer wall surfaces of the side walls and the bottom wall are formed with a plurality of crests arranged at intervals and a plurality of troughs each connected between every adjacent two of the crests. The crests and the troughs form a continuous corrugated surface, which can withstand greater stress without causing surface wrinkles.

A wheel rim retainer includes an annular unit, a first end connecting member movably coupled at one end of the annular unit, and a second end connecting member movably coupled at an opposed end of the annular unit. The annular unit includes a plurality of hinged members movably coupled with each other in an edge-to-edge manner, wherein each of the hinged members has a width larger than a width of the wheel well. The second end connecting member is detachably coupled with the first end connecting member for encircling the hinged members around a hub surface of a wheel rim to cover a wheel well thereof so as to prevent a bead of a tire falling at the wheel rim when the tire is deflated.

A rim (5) for a bicycle wheel having a body (20) with a substantially annular extension with a radially outer portion (22) shaped for coupling with a tire is disclosed. The radially outer portion (22) has a hole (39) for an inflation valve. The radially outer portion (22) also includes, at the hole (39) and/or in an area proximal to the hole (39), at least one cross section having a different shape from that at an area distal from the hole, so as to form at least one second surface discontinuity (35) along the annular extension of the radially outer portion (22). The second discontinuity (35) makes it easier to assemble to wheel and allows an optimal coupling to be made between the rim (5), inflation valve, and tire, in the case of a tubeless wheel, and between rim (5), air chamber and tire, in the case of a wheel with an air chamber.

The coefficient cycling aero foil system is designed to reduce drag and turbulence from a tire and spokes used to support a bicycle wheel. The system is integrated into a rim on a bicycle wheel which allows for increased forward momentum by cutting drag and reducing wheel turbulence that occurs during the rotation of a bicycle wheel. The foils may be strategically placed for optimum aerodynamic wind flow and are precisely angled to force wind past the foil creating increased forward momentum.

A wheel rim including a flange profile on a tire side of an open end flange of the wheel rim, the flange profile defined by the equation: $y_1=(a\mathrm{Theta}1+\frac{1}{{\left(1+\mathrm{Exp}\left(a\mathrm{Theta}3+a\mathrm{Theta}4.Math.X_1\right)\right)}^{\mathrm{aTheta}5}}$

A wheel and a rim with weight reduction sockets are provided. The rim includes an inner flange, a middle portion and an outer flange, the inner flange, middle portion and outer flange are all annular and are connected end to end to form a cylindrical rim, in which the middle portion of the rim includes weight reduction sockets; and the weight reduction sockets are of regular hexagons, and are arranged adjacently on the outer side of the middle portion of the rim in the shape of a honeycomb. The weight of the hub is reduced by designing the weight reduction sockets in a specific shape for the outer rim of the hub and selecting the size of the weight reduction sockets.

A wheel and a rim with weight reduction sockets are provided. The rim is made of an aluminum alloy and includes an inner flange, a middle portion and an outer flange, the inner flange, middle portion and outer flange are all annular and are connected end to end to form a cylindrical rim, in which weight reduction sockets are provided on the outer surface of the middle portion of the rim; the weight reduction sockets are rectangular ones, and are arranged in lattices in turn; and 3-5 rows of weight reduction sockets are arranged annularly on the outer surface of the middle portion of the rim.
