Carbon fiber spoke and manufacturing method thereof

A carbon fiber spoke, comprising a spoke body made of carbon fiber, a screw bushing fitted and connected with a rim and a nut cap bushing fitted and connected with a hub, wherein a first end part and a second end part of the spoke body are respectively fixedly provided with a solid joint;

• an outside surface of the solid joint is provided with a first tapered section with a first diameter and a second diameter, wherein the first diameter is smaller than the second diameter;
• the screw bushing and the nut cap bushing are provided with mounting holes, wherein a hole wall surrounding the mounting hole is provided with a second tapered section;
• the mounting hole of the screw bushing and the mounting hole of the nut cap bushing are respectively fixed to the solid joint on the first end part and the second end part of the spoke body;
• the second tapered section of the mounting hole and the first tapered section of the solid joint are fit and connected together;
• wherein the outside surface of the solid joint is provided with a first rotator section connected with the first tapered section;
• an outer diameter of the first rotator section is equal to or less than a maximum outer diameter of the first tapered section;
• the hole wall of the mounting hole is provided with a second rotator section connected with the second tapered section;
• wherein a minimum outer diameter of the first tapered section is larger than an outer diameter of the spoke body, and a first step surface is formed on the solid joint by an outer diameter difference;
• a minimum inner diameter of the second tapered section is larger than an inner diameter of the second rotator section, and a second step surface is formed on the mounting hole by the outer diameter difference;
• the first step surface and the second step surface are jointed together.
