Method for obtaining a suspension arm for automotive vehicles and suspension arm

A method for obtaining a suspension arm for automotive vehicles which comprises obtaining two identical parts to form a body, where each part is obtained by means of the following sequential steps:

• a) cutting a sheet metal or composite sheet forming a base plane, such that a central segment and two ends are defined, and
• b) drawing at least one hole in an area corresponding to each end, where each hole has a geometric center,
• characterized in that the method then comprises the following sequential steps:
• c) stamping or shaping each part forming in its central segment two flanges consisting of a first flange and a second flange located on opposite sides of the central segment and oriented perpendicular to the base plane, where said flanges have an asymmetrical arrangement with respect to a midplane passing through the geometric centers of the holes of the two ends and is perpendicular to the base plane, the second flange being separated from the midplane a distance equal to the separation of the first flange from the midplane plus a distance at least equal to the value of the thickness of the sheet or plate, and
• d) starting from two parts in the same position, rotating a first part 180° with respect to a longitudinal axis defined between the geometric centers of the holes of both ends until both parts are facing and with their corresponding base planes parallel to one another, moving both parts closer with the corresponding geometric centers of the holes aligned with one another, the flanges of both parts being fitted to and overlapping one another such that a overlap is defined in the flanges.
