  • Energy absorbing propeller shaft system
    Patent number: 7175532
    Abstract: A dual-sectioned automotive propeller shaft features a weakened area in a first section. Under an axial load, the first section buckles transversely to a longitudinal axis of the shaft to absorb substantially all of the energy exerted against the shaft. A second section of the shaft is thereby isolated from consequences of the axial load enabling its placement and proximity to other components mounted to the undercarriage of the vehicle.
    Type: Grant
    Filed: January 9, 2004

    Assignee: DaimlerChrysler Corporation
    Inventors: Nicolaos Tapazoglou, Hai Gu, Gerald F Burke, Troy M Cornell, James M. Culp, Mark J. Kirschmann, Douglas L. Nieset
