Abstract:
A structural element comprising a vehicle suspension control arm is constructed from a complex, single piece, sheet metal stamped component formed from a material of uniform thickness. The stamping is configured with the correct plan view shape and formed into an I-beam cross-section comprising a central web portion and two flange portions. The central web portion is configured as a single material thickness and the flange portions comprise upstanding and downstanding closed sections with a continuous double returned segment. The open ends of the sheet metal terminate at or near the central web portion and are welded to the web portion, and in an alternative embodiment also to the continuous double returned segment, to create a favorable structural I-beam section with flange portions twice the thickness of the web portion.
