Abstract
A propeller shaft assembly comprises a connect shaft portion, a plungable constant velocity joint, and a hollow shaft portion with a cavity. An energy absorbing material is disposed within at least a portion of the cavity. The material absorbs energy when the constant velocity joint plunges into the hollow shaft portion when a predetermined force is exerted upon the constant velocity joint. The energy absorbing material may comprise a foam material, such as, an organic foam, a cellular foam, a synthetic foam, a metal foam, and the like. In addition to absorbing energy, the foam material minimizes the transmission of high frequency vibration of the propeller shaft assembly.
