ABSTRACT:
A control arm includes a connection tube and two mounting eyes respectively attached to opposite ends of the tube. Each mounting eye has a sleeve and a rubber-metal element vulcanized into the sleeve. In a method of making such a control arm, an elongate tubular member is sized to a sleeve blank of a length commensurate with the tube. Parallel thereto, an extruded profile is made with a cross sectional configuration of the sleeve and subsequently sized to the axial height of the sleeve. Rubber-metal elements are vulcanized into the sleeve blanks which together with the tube are then clamped, axially shiftable, in a friction welding machine for subsequently fabricating protruding collars on the sleeves through material removal and joining the end surfaces of the protruding collars with the end surfaces of the tube. While still clamped, the tube and the mounting eyes are calibrated through cold upsetting and the joints are smoothed.
