Patent number: 5689882Abstract: 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.Type: GrantFiled: September 12, 1995Date of Patent: November 25, 1997Assignees: TRW Steering Systems Japan Co.
