Manufacturing method of spoke assembly

A manufacturing method of a spoke assembly, comprising the following steps:

• S1:
• providing a preform made of cylindrical carbon fiber;
• S2:
• providing a first connector and a second connector, wherein the first connector and the second connector each have a conical through hole;
• S3:
• enabling the first connector and the second connector to sleeve appropriate positions of a middle portion of the preform via the conical through holes, respectively;
• S4:
• wrapping consecutive carbon fiber layers around two ends of the preform to form conical pillar sections;
• S5:
• placing the preform into an end forming mold, and curing the conical pillar sections at the two ends of the preform at one time to form fixed joints, wherein fibers in an inner carbon fiber layer and an outer carbon fiber layer of the consecutive carbon fiber layers wrapped sequentially are distributed continuously along a taper of the fixed joints;
• S6:
• applying pulling forces toward end sides to the first connector and the second connector, to force the first connector and the second connector to respectively sleeve the fixed joints at the two ends of the preform;
• S7:
• wrapping a continuous carbon fiber layer on the middle portion of the preform, and placing an entirety of the preform into a main body forming mold for curing, such that the middle portion of the preform forms a main body and the preform is processed into a spoke;
• and
• S8:
• applying the pulling forces toward the end sides to the first connector and the second connector again, to force the first connector and the second connector to sleeve the fixed joints more tightly than in the step S6, and ensuring an overall length of the spoke assembly meets a specified length, thereby forming a complete spoke assembly.
