A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.

The present invention discloses an opening-prefabricated carbon fiber spoke and a method for preparing thereof. The opening-prefabricated carbon fiber spoke includes: a spoke body made of carbon fiber, a nipple, and a nipple head. Both ends of the spoke body are a first fixed connector and a second fixed connector. The nipple is sleeved on the second fixed connector of the spoke body. A forked part of the second fixed connector is provided with a wedge pin. According to the present invention, a slope is formed at both ends of the spoke body, and the two ends are increasingly tight under an action of a pulling force, which greatly improves a tensile strength.

A non-pneumatic tire (1) of the present invention includes an attachment body (11) attached to an axle, a ring-shaped body (13) which surrounds the attachment body (11) from the outside in a tire radial direction, and coupling members (15) which displaceably couple the attachment body (11) to the ring-shaped body (13), wherein a plurality of coupling members (15) are arranged in a tire circumferential direction and include elastic coupling plates (21 and 22) whose opposite ends are respectively coupled to the attachment body (11) and the ring-shaped body (13), and a bending rigidity EI1 of the elastic coupling plates (21 and 22) represented by E1W1t1.sup.3/12 when the average thickness in the tire circumferential direction is t1 (mm), the average width in a tire width direction H is W1 (mm), and the Young's modulus is E1 (MPa) is smaller than the bending rigidity EI2 of the ring-shaped body (13) represented by E2W2t2.sup.3/12 when the average thickness in the tire radial direction is t2 (mm), the average width in the tire width direction H is W2 (mm), and the Young's modulus is E2 (MPa).

An article includes having a braided fiber having a first end and a second end, and a rod having a first end and a second end, whereby the first end of the rod is threaded and wherein the second end of the rod is disposed inside the first end of the braided fiber.

A wheel for a two wheeled vehicle including a flange and a plurality of spokes, the spokes connecting the rim to the flange, wherein brake force spokes of the plurality of spokes are stronger than drive force spokes of the plurality of spokes. In one alternative, the flange has an inner and an outer area.

The present invention relates generally to a spoke reinforcing method and reinforced structure of spokes, the method includes a main body of spoke with a head end and a thread part on two ends respectively, a neck is disposed below the head end, the neck is forged at least twice to enlarge the cross-section area of the neck, and to increase the density and strength of the metal grains therein; a hexagonal columnar reinforced structure is forged below this high density neck, and the high frequency lateral stress on the lower part of the high density neck is buffered by the optimal compressive strength and flexural strength of the hexagonal column, the reinforced structure of spokes produced by this method can reduce the spoke fracture probability and prolong the spoke lifetime.

A spoke for use in connection with a wheel, the spoke having a braided fiber having a first end and a second end, a rod having a first end and a second end, whereby the first end of the rod is threaded and wherein the second end of the rod is disposed inside the first end of the braided fiber.

A wheel with flexible spokes, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength.

A combination structure of a hub and spokes is provided, including: a hub shell, having separate small and large flanges, the small and large flanges having first and second assembling holes, respectively; a plurality of first spokes, assembled to one of the first assembling holes and a wheel rim; a plurality of second spokes, including cylindrical spokes and aero bladed spokes, the cylindrical spokes and aero bladed spokes being alternatively assembled to the second assembling holes and to the wheel rim; as viewed along an axial direction of the hub shell, every two of the second spokes which are neighboring to each other intersect with each other to define an intersecting area, each first spoke extends and passes through one of the intersecting areas.

A spoke for an at least partially muscle-powered bicycle and wheel including a spoke where the spoke comprises a spoke body with a hub-side, first end and a rim-side, second end and the first end and the second end are remote from one another. The spoke body is elongated and includes at least one first center region disposed closer to the first end than to the second end, and at least one second center region disposed closer to the second end than to the first end. The first center region and in the second center region of the spoke body each include flattened cross-sections substantially accommodated in a longitudinal plane. In the second center region the spoke body is configured more asymmetric than in the first center region.
