CARBON FIBRE SPOKE AND MANUFACTURING METHOD THEREFOR

The present invention discloses a carbon fiber spoke and a manufacturing method thereof. The carbon fiber spoke includes a spoke body made of carbon fiber, a screw bushing that can be fit and connected with rim and a nut cap bushing that can be fit and connected with the hub. Two end parts of the spoke body are provided with solid joints. The outside surface of the solid joint is provided with a first tapered section with a small diameter close to the spoke body and a large diameter away from the spoke body. The screw bushing and the nut cap bushing are provided with penetrable mounting holes. The 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 two solid joints; the second tapered section of the mounting hole and the first tapered section of the solid joint are fit and connected together. The forces that the rim and the hub respectively act on the screw bushing and the nut cap bushing are both tensile forces, which make the second tapered section subjected to an outward acting force relative to the first tapered section. The acting force makes a higher tightness between the solid joint and the screw bushing or the nut cap bushing.
