AERODYNAMIC BICYCLE RIM AND WHEEL
An aerodynamic bicycle rim comprising: a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat a bicycle tire; a nose; and a set of sidewalls, each sidewall extending radially from the nose of the aerodynamic bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a maximum rim body width that is greater than a maximum width of the bicycle tire. The aerodynamic bicycle rim is operable to seat the bicycle tire so that the aerodynamic bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape.
METHOD FOR MANUFACTURING A LIGHT-ALLOY HYBRID WHEEL INCLUDING A FRONT FLANGE AND A RIM
A process for manufacturing a light-alloy hybrid wheel, implements the following separate operation phases: making a flange with an internal profile capable of constituting a tire bead seat; making a rim with, on one side, an outer profile capable of constituting a tire bead seat and, on the other side, a circular flank for assembly with a part of the flange; and assembling the flange with the rim, at the seat of said flange and the circular flank of the rim. The rim is made according to the following consecutive operations: an operation of manufacturing a circular flank; then an operation of expanding said circular flank to the size of the final rim in a single step; then an operation of cold or hot flospinning of said circular flank so as to obtain the rim in the final shape and profile thereof, comprising a shoulder only on the side that will not be welded to the flange.

Wheel rim structure
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.
METHOD FOR MANUFACTURING A ONE-PIECE WHEEL BY FORGING AND A ONE-PIECE WHEEL MANUFACTURED THEREBY
A method for manufacturing a one-piece wheel by forging includes: producing an integral forging comprising: a disc portion, a rim portion, and an annular protrusion protruding from one side of the disc portion in a forging method; producing an outer bend by bending the annular protrusion through a flow-forming process; and forming a hollow portion by welding one end of the outer bend to one side of the rim portion. The method manufactures the one-piece wheel having stronger shear strength and stiffness and better fatigue life even while reducing the noise using the forging method.
Centerless wheel assembly
The present disclosure may relate to a wheel that may include first and second exoskeleton plates. The wheel may also include first and second roller guide assemblies that each include one or more bearings, a roller guide coupled with the one or more bearings, and a shaft spanning the first and second exoskeleton plates and coupled with the roller guide such that the roller guide rotates around the shaft. The wheel may also include a tire and a centerless rim coupled with the tire. The centerless rim may be configured to have a shape that corresponds to a shape of the roller guide, and the roller guide may be configured to contact the centerless rim as the centerless rim rotates. The wheel may also include a first limiter to maintain contact between the centerless rim and the roller guide, and a second limiter.

CONNECTION STABILIZING MECHANISM BETWEEN SOLID TIRE AND BICYCLE RIM
A connection stabilizing mechanism between a solid tire and a bicycle rim. The connection stabilizing mechanism includes multiple fastening members connecting a solid tire with a bicycle rim. Each of the fastening members has a plate-shaped base section engaged with the bicycle rim and an extension section inserted into the solid tire. A free end of the extension section is inserted into the solid tire. A ratio of an extension length of the extension sect ion to a tire height of the solid tire is between 1:1.5 and 1:2.6, thereby maintaining a relative position of the center of a main body of the solid tire relative to the rim. Thus, the solid tire is prevented from being detached from the rim due to excessive lateral movement of the central position of the main body of the solid tire.
