  • Method of fabricating a shaft assembly
    Patent number: 7143510
    Abstract: An assembly provides metallic ends to a composite shaft and a method of fabricating such an assembly. The composite shaft is preferably comprised of reinforced fibers. A metallic inner sleeve is positioned in the cavity of one end of the shaft. A metallic outer sleeve is positioned around the end of the shaft having the inner sleeve therein. The outer sleeve may include structural features, such as dimples, that ensure a stable connection between the sleeve and the shaft. The sleeves are compressibly forced onto the shaft, thereby forming the assembly. Both sleeves are metallic, and therefore provide a surface onto which weld joints can be formed. A preferred method of assembly includes the steps of expanding the inner sleeve and compressing the outer sleeve against the shaft.

  • Exhaust treatment device for automotive vehicle having one-piece housing with integral inlet and outlet gas shield diffusers
    Patent number: 6293010
    Abstract: An exhaust treatment device for an internal combustion engine includes a generally cylindrical substrate and sealing system which are swaged in place within a one-piece housing. The one-piece housing includes segmented inlet and outlet gas shields and diffusers which are spun from a single piece of tubing which also contains the substrate. The spun inlet and outlet gas shields and diffusers have segmented configurations including multiple concave and convex sections produced by spin-forming of the housing. The exhaust treatment device is assembled without the need for welding or any other high temperature operation.
