Method to produce a one piece hollowed spoke

This invention is related to a one-piece hollowed spoke and the process method. The procedure contains 1. Selection of Work piece. 2. Initial Forge (with the work piece in the mold, and forged as extended and radial shape of spoke) 3. Slotted and Draw Out (drilling and cutting the spoke as slotted and hollowing the spoke by shrinking) 4. Fluid Injection (open a small hole on the hollow spoke after drawing out and seal it after injecting the fluid into the spoke) 5. Further Processing (re-forging the spoke that contains the fluid for semi-finished product) 6. Draining the Fluid (drilling a hole on the spoke and draining the fluid, processing the assembly hole on the spoke) With the procedure above the wheel with hollowed spoke would not only be able to finish as a one-piece model, but also able to be assembled on the system with bolts. This invention reduces the cost of the raw material and the weight of the system, which directly increases the effectiveness of power and is much friendlier to the environment at the same time.
