Method and apparatus for manufacturing spokes

A method and a device are provided for manufacturing spokes from a wire material, in particular for at least partially muscle-powered two-wheeled vehicles. The spokes include a spoke shaft having at least two shaft sections. The shaft sections differ in at least one cross-section. For shaping the cross-sections, the wire material is reshaped at least in sections by means of a shaping tool. The relative position of the wire material relative to the shaping tool is varied in the axial direction during reshaping. For shaping the cross-sections in the two shaft sections the relative position of the wire material relative to the shaping tool is varied by way of different positioning movements.

INTEGRALLY INJECTION MOLDED WHEEL WITH HIGH STABILITY

A stable, low-weight wheel which is particularly suitable for high system-weight bicycles, such as electrically powered bicycles and cargo bikes, includes a hub, at least three solid-body spokes disposed rotationally symmetrical to the wheel axis, and a rim. The body of the hub, spokes and rim is made in one piece by injection molding of a glass-fiber reinforced thermoplastic. The spokes have an S-shaped cross-section with an opening angle which increases in the direction of the rim, taper from the rim towards the hub in a central cross-section of the wheel, and taper from the hub towards the rim in a wheel cross-section running through the center of least one spoke. A method for producing the wheel is also provided.

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.

SPOKE FABRICATION FOR A NON-PNEUMATIC WHEEL

An exemplary spoke for a non-pneumatic wheel. The spoke can be manufactured with a reinforcement structure having reinforcement elements and one or more layers of material. The spoke can also be provided in various shapes and configurations. The spoke includes anchors that allow the spoke to be more readily incorporated into, or removed from, a non-pneumatic wheel. More particularly, the anchors also allow the spoke to be joined as one-piece with the non-pneumatic wheel or releasably connected on one or both ends with the non-pneumatic wheel.

Bicycle wheel

The invention relates to a bicycle wheel made of a fiber composite material, including a rim, a plurality of spokes, and a center, wherein the spokes each have a first and second spoke section extending between the rim and the center, wherein the first and second rim section have a curved shape in a laminated state and the two rim sections extend straight in a pretensioned state.

Wheel and spoke, in particular for a bicycle

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.
