Abstract
The present invention discloses a carbon fiber spoke and a method for preparing the same. The 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.
Claims10
A carbon fiber spoke, comprising:
- a spoke body made of carbon fiber, a nipple connected to a wheel rim, and a nipple head connected to a hub, ends of the spoke body respectively have a first fixed connector and a second fixed connector, the first fixed connector is provided with a diameter-expanded part, the second fixed connector is provided with a forked part, the nipple and the nipple head are provided with penetrating mounting holes, the nipple head is sleeved on the first fixed connector of the spoke body, the nipple is sleeved on the second fixed connector of the spoke body, and the forked part of the second fixed connector is provided with a wedge pin.
A method for preparing a carbon fiber spoke, comprising steps of:
- step 1:
- forming a carbon fiber spoke body by thermoforming, a first end of the carbon fiber spoke body being an expanded part, and a second end of the carbon fiber spoke body being a forked part in a closed state;
- step 2:
- sleeving a nipple head from a forked end of the carbon fiber spoke body, and placing the nipple head in place, so that an expanded end of the carbon fiber spoke body is inserted into the nipple head;
- step 3:
- sleeving a nipple from the forked end of the carbon fiber spoke body, applying an adhesive on the forked end of the carbon fiber spoke body, and then moving the nipple in place;
- step 4:
- applying the adhesive to a wedge pin and a part at which the forked end of the carbon fiber spoke body is bonded to the wedge pin;
- step 5:
- pressing the wedge pin into the forked end of the carbon fiber spoke body, so that the forked end of the carbon fiber spoke body expands and compresses an inner surface of a gradient hole of the nipple;
- and
- step 6:
- heating an assembled spoke assembly in an oven to cure the adhesive.
