Abstract
PURPOSE: To reduce the total weitht of a rack shaft without sacrificing its strength, by making flat surfaces with rack tooth on the external surface of a hollow bar through plastic forming.
CONSTITUTION: A rack shaft 3 is fit loose in a case 2 of a rack-and-pinion steering gear 1, rack tooth 4 being engaged with a pinion 5 interlocked with a steering handl. For producing the rack shaft 3, a hollow round bar undergoes plastic working such as forging to form a flat surface 8a on which the rack tooth 4 is to be formed and another flat 8b on the opposite side. Since the hollow section 9 of the bar is deformed similar to the external form, the thickness of flat 8a is, not reduced and since the rack tooth 4 is formed on the thick flat the mechanical strength of the tooth 4 and the rack shaft itself is not sacrificed, while the weight is reduced.
