Abstract: The invention relates to a pivot connection type assembly comprising a shaft and first and second connection parts, each receiving the shaft so as to enable them to pivot relative to each other, the first connection part being arranged axially between a first end of the shaft and a radial plane, while the second connection part is arranged axially between said radial plane and the other end of the shaft. The shaft is hollow and includes an inside section that presents a radial dimension at least in a first axial plane and over a first segment of the shaft extending axially between the first end and the radial plane, which radial dimension varies, decreasing on axially approaching the radial plane. The assembly includes a ring interposed radially between the shaft and a bore of the first connection part, and presenting radial thickness that varies.

Abstract: The invention provides a method of fabricating a force transfer part (100) including at least one lug (108) made of composite material that is to receive a pin for making a pivot connection with another part, the method comprising making a fiber preform for a main body of the part and making a preform for a reinforcing ring out of discontinuous long fibers, making the reinforcing ring preform to match the dimensions of at least one bore in the preform of the main body, inserting the reinforcing ring preform in the bore of the preform of the main body, and polymerizing the reinforcing ring and main body preforms in injection tooling. The invention also provides a force transfer part obtained by such a method.
