INTERMEDIATE SHAFT FOR DRIVE SHAFT
Document Type and Number:
WIPO Patent Application WO/2010/116883
Kind Code:
A1
Abstract:
Disclosed is an intermediate shaft for a drive shaft wherein the bending rigidity is enhanced while reducing the weight by providing an FRP layer (120) on the outer circumference of a steel hollow shaft (102). The steel hollow shaft (102) consists of the intermediate portion (104) and the coupling portions (106) on the opposite sides of the intermediate portion (104), and the steel hollow shaft is hollow over the entire length and the FRP layer (120) is provided on the outer circumference of the intermediate portion (104). More specifically, there are several modes of fitting FRP formed in the shape of a pipe to the outer circumference of the hollow shaft (102), wrapping a bundle of carbon fibers impregnated with resin around the outer circumference of the hollow shaft (102), and wrapping CFRP formed in the shape of a sheet around the outer circumference of the hollow shaft (102).
