The invention relates to a method for the manufacture of axle bracket halves. According to the invention, an axle bracket half is produced by extrusion moulding of an initial body, in which through changes in the cross- section of the shank region b the moment of resistance of the axle half can be increased with a saving of material. In the method of the invention, first a shank region b and a depression region c are formed from the ingot through hot-extrusion. The depression region c is then expanded and extruded into a rectangular shape and the shank region b formed into a square cross-section. In a final extrusion step the depression region c takes its finished form with local wall thickening. Openings for the drive- and cover side of the axle half can be punched out subsequently. <IMAGE> |
