摘要： A method of producing a spindle that can be easily press fit into a knuckled suspension arm with high productivity. A round bar is forged by a header to form a work in process part which is, in turn, thermally refined. If necessary, shot blast and lubrication are applied to the exterior surface of the work in process part. Subsequently, by rolling the work in process part, screw threads are formed on a male screw portion. The work in process part is set and finished in a press. The peripheral surfaces of the bearing attachment portion as well as the knuckle press fit portion of the work in process part are finished in a press. Since the surface of the knuckle press fit portion of the spindle is formed or extruded in the press, the portion can be easily press fit into a knuckled suspension arm with little resistance. The method of producing the spindle obviates the necessity of machining and grinding thereby providing enhanced productivity.

摘要翻译： 一种制造能够以高生产率容易地压配合到转向悬臂的主轴的方法。 圆棒由头部锻造以形成加工部件的工件，这又是热精炼的。 如果需要，喷砂和润滑被施加到工件的外表面上。 随后，通过轧制加工部件中的工件，在螺母部分上形成螺纹。 工作中的工作部分在新闻中设置和完成。 轴承安装部分的周边表面以及加工部件的转向节压配合部分在压机中完成。 由于主轴的转向节压配合部分的表面在压力机中形成或挤压，所以该部分可以容易地压配合到具有小阻力的转向悬臂中。 主轴的制造方法不需要加工和研磨，从而提高生产率。
