Wheel component, method of manufacturing, and tool device

A method of manufacturing a wheel component for at least partially muscle-powered vehicles and in particular bicycles with a plurality of component parts, which are integrally interconnected and form a rim with a plurality of integrally configured spokes, wherein the rim and the spokes are manufactured of at least one fibrous composite material by injection molding, comprising at least the following process steps:

• injecting the at least partially liquefied fibrous composite material into at least one cavity of a tool device;
• injecting at least one fluid into the at least partially liquid fibrous composite material within the cavity, to form at least one hollow space within the solidified component part, to thus form the component parts of the rim;
• and wherein at least one further component part, which forms at least part of a spoke, is manufactured by way of the following process steps:
• within the at least one further cavity of the tool device, a mold core device is disposed for forming at least one hollow space within the further component part;
• the fibrous composite material is injected into the at least one further cavity for forming the other component part;
• and
• the mold core device is retracted from the at least partially solidified fibrous composite material to form a cavity (109b) in the spoke;
• the wheel component with the rim and the integrally interconnected spokes is removed from the tool device.

An apparatus with a tool device for manufacturing a wheel component for at least partially muscle-powered vehicles and in particular bicycles,

• wherein the tool device serves to manufacture wheel components comprising:
• a plurality of component parts, wherein the component parts are integrally interconnected and form a rim and a plurality of integrally configured spokes, wherein the rim and the spokes are manufactured in the tool device of a fibrous composite material by injection molding,
• wherein the tool device, for forming the component parts of the rim and the spokes, comprises at least two molding devices, which form cavities for forming a plurality of integrally interconnected component parts of the wheel component, wherein, for forming at least one component part of the rim, at least one injection port for injecting an at least partially liquid fibrous composite material and at least one injection nozzle for injecting at least one fluid is comprised within the one cavity for forming at least one hollow space within the component part of the rim;
• and wherein the tool device comprises at least one further cavity, which is connected with the cavity with the injection port;
• and wherein the tool device comprises a plurality of mold core devices, which, for forming hollow spaces in the spokes as component parts, are each retractable into, and extendable out of, the further cavities.
