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.
