DRIVE SHAFT ASSEMBLY USING CARBON FIBER REINFORCED PLASTICS

摘要

A drive shaft assembly according to the present invention comprises: a core shaft (10) having a hollow shape; coupling shafts (20) connected to both sides of the core shaft (10); and a shaft cover (30) coupled in a shape in which the shaft cover (30) encompasses the outer circumferential surfaces of the core shaft (10) and the coupling shafts (20), wherein the shaft cover (30) is coupled to fastening protrusions (24) formed on the outer circumferential surfaces of the coupling shafts (20). The present invention, after forming the fastening protrusions on the outer circumferential surfaces of the coupling shafts on both sides of the core shaft, enables the shaft cover to have a structure in which the coupling thereto of fastening protrusions simultaneously occurs with a process in which carbon fibers are braided by a braiding method on the outer circumferential surfaces of the coupling shafts and the core shaft, thereby increasing the coupling strength between the coupling shafts and the core shaft.
