The present disclosure may relate to centerless wheel assembly that includes a centerless rim including a first center point laying in a first plane generally defined by the centerless rim. The centerless wheel assembly may also include a centerless ring gear coupled to the centerless rim such that rotation of the centerless ring gear causes a corresponding rotation of the centerless rim. The centerless ring gear may include a second center point laying in a second plane generally defined by the centerless ring gear, and the first plane may be generally parallel to the second plane. Additionally, the centerless ring gear may be shaped to interface with a drive gear that drives the centerless ring gear.
摘要:
A bicycle disc or spider wheel including: a hub; a rim having a radially outer tire-coupling region, a first sidewall, a second sidewall; an axis of rotation; and a median plane. A pair of pretensioned disc or spider wheel-type structural elements are integral with the hub and with the rim. The first sidewall extends on a first side of the wheel, with respect to the median plane, on which a component of a motion transmission system or, when there is none, a disc of a disc brake is provided at the hub, and the second sidewall extends on the opposite side, with respect to the median plane. The first sidewall of the rim has a minimum distance from the median plane that is smaller than that of the second sidewall of the rim.

A bicycle rim is basically provided with a first annular side wall, a second annular side wall and an annular bridge. The first annular side wall includes a first braking contact portion. The second annular side wall includes a second braking contact portion. The annular bridge extends between the first and second annular side walls. At least one of the first and second braking contact portions has a plurality of soft additives at least partially embedded in a non-metallic layer.

A bicycle wheel rim including an outer annular portion adapted to receive a tire and an inner peripheral radial portion that has both a plurality of circumferentially arranged spoke openings and a braking surface on this portion.
摘要:
A FRP rim for a bicycle, including a radially outer tire-engaging portion and a radially inner spoke-engaging portion. A first sidewall is in a spaced configuration with a second sidewall. The first and second sidewalls extend between the radially outer tire-engaging portion and the radially inner spoke-engaging portion. A brake track is disposed on each of the first and second sidewalls including a layer of microparticles.
摘要:
A method of manufacturing carbon fiber rim for bicycle comprising steps of: preparing at least one preformed mold, separating from the preformed main mold, connecting with an inner framework, and solidifying; wherein plural carbon-fiber prepreg wires are repeatedly on a preformed carbon fiber case at least twice so as to form at least two rolling layers, and each rolling layer is at varying angle. Also, a carbon fiber rim for bicycle contains: an inner framework having a profile corresponding to a carbon fiber rim; and a preformed carbon fiber case at least covering a part of the inner framework and being successive rolled by plural carbon-fiber prepreg wires relative to a set angle of an axis normal.

A carbon fiber rim contains: a body, two clamping pieces, and a plurality of covering layers. The body includes a recessed fixing face defined on an outer diameter thereof so as to fix a tire and two connecting faces formed on two sides thereof so as to align with the two clamping pieces, and each clamping piece is a circular loop and corresponds to a profile of an outer peripheral side of the body. The plurality of covering layers are fitted and surround around the body and the two clamping pieces. Thereby, the two clamping pieces are fixed on the two connecting faces of the body by using the plurality of covering layers so that the two brake blocks do not contact with the body directly and brake a bicycle wheel via the two clamping pieces.
摘要:
The bicycle wheel manufactured by the method of the present invention is made of composite material and has two opposite braking surfaces, each of which is coated with a fluoride polymer layer. Specifically, the braking surfaces are sand blasted to remove a releasing agent layer coated on the wheel. The wheel is, thereafter, placed in a spraying machine at about 100 degree Celsius and then the braking surfaces are spray-coated with a material selected from the group consisting of polytetrafluoro ethylene, fluoride ethylene-propylene copolymer, polyfluoroalkyl, ethylene-tetrafluoro ethylene copolymer and the mixture thereof until a thickness of the material is bigger than 0.4 cm. Thereafter, the wheel is gradually heated to make the material set and form the fluoride polymer layers.
