<p>The invention relates to a control arm (1) comprising arm sections (4) and an intermediate section (11). The control arm is made as one integral piece from a processed work piece, preferably from an extruded profile provided with a base wall element (2) and at least one perpendicular side wall (3). A first part of the work piece constitutes the arm sections and a second part constitutes the intermediate section. The arm sections are formed as an arc with a free space there-between. The invention also relates to a process for manufacturing such control arm (1) comprising the steps of: - extruding a profile comprising at least one base wall and at least one wall standing perpendicular on the base wall, - cutting work pieces of predefined length from the profile, - cutting excess material from the base wall element, - plastically forming each work piece, - trimming at least a part of the walls of the work piece, - providing the work piece with holes.</p> |
