Abstract: An automotive driveline component includes a housing and a dampener carried by the housing. The dampener includes a plurality of shims joined together via at least one joint through which vibrations are transmitted among individual shims of the plurality of shims. When the housing experiences vibrations during use of the automotive driveline component, the vibrations are transmitted to the plurality of shims and relative movement among individual shims of the plurality of shims dampens the vibrations experienced by said housing.

Abstract: A damped automotive driveline component can be propshaft, a bar shaft, a torque tube housing, a power transfer unit (PTU) housing, or a final drive unit (FDU) housing, among other possibilities. The component is equipped with a dampener in order to dissipate vibration experienced during use of the component. The damper includes metal wire strands. Relative movement among the metal wire strand is believed to damp the vibrations.

Abstract: A frangible telescopic propeller shaft includes an elongated hollow cylindrical body, a reduced diameter intermediate portion along a length of the body, and at least one spin-formed transition area between the intermediate portion and the body. The transition area includes a frangible feature wherein at least a part of the cylindrical body lies over the intermediate portion such that, in response to a sufficient axial force, the frangible feature fractures to telescope the body over the intermediate portion.

Abstract: A propeller shaft assembly includes a thin-walled tubular member, a connecting member fixed to each end of the tubular member, and a support member fixed within the tubular member. The support member includes a foamed plastic impregnated with a high modulus resin or cement extending a first length (L1) within the tubular member and engaging an interior surface of the tubular member to increase the bending frequency of the propeller shaft assembly.

Abstract: A propeller shaft assembly includes a thin-walled tubular member, a connecting member fixed to each end of the tubular member, and a support member fixed within the tubular member. The support member includes a plurality of radial elements extending a first length (L1) within the tubular member and engaging an interior surface of the tubular member to increase the bending frequency of the propeller shaft assembly. In one example, the support member includes a central hub coaxially located within the tubular member and the radial elements extend from the central hub to the interior surface of the tubular member. The radial elements can include enlarged end portions for engaging the interior surface of the tubular member. The radial elements, at their ends, can also include either axial or circumferential grooves which act as an adhesive reservoir.
