摘要： The invention concerns a method of manufacturing a joint housing, in particular for vehicle track rods, having an integral shaft with an internal thread designed to hold a longitudinal pin, the housing being produced from a blank with a ball-like enlargement at one end. In order to ensure low manufacturing costs and low consumption of energy and materials, a longitudinal cavity with a diameter exceeding that of the internal thread and a length exceeding that of the threaded section is first produced in the shaft of the blank by rearwards cup extrusion and the diameter of the threaded section subsequently reduced to that of the thread core while at the same time shaping the surface of the wall to give a flat key face, the overall process being a cold-forming one. Finally, both the external and internal features of the housing are produced by heading, cupping, punching and forming to size perpendicular to the longitudinal axis in the region of the enlargement.
