Abstract
A rotary torque shaft including a tube made of a composite material having a plastic matrix and a metallic tubular insert fixedly mounted around a recessed longitudinal outer surface portion of the tube so as to link the tube mechanically to a functional mechanical assembly which is supported by the insert. The insert has in cross section a non-circular inner surface profile which is complementary in shape to a profile of the outer surface of the tube.
Claims11
A shaft for transmitting rotational movements forces, comprising a tube made of a composite material having a plastic matrix and which includes a set back longitudinal portion located between two spaced longitudinal portions of the tube which respectively extend from opposite ends of the set back longitudinal portion, the set back longitudinal portion having a reduced inner dimension relative to the two longitudinal portions of the tube and having in cross section at least one non-circular outer surface profile, and a metallic tubular insert fixedly seated around the set back longitudinal portion of the tube without covering the two longitudinal portions of the tube, the metallic tubular insert being designed to link the tube mechanically to a functional mechanical assembly which is supported by the insert and having in cross section at least one non-circular inner surface profile which is complementary in configuration to the at least one non-circular outer surface profile of the set back longitudinal portion of the tube.
