| The invention relates to a cold forming method for producing ball journals comprising a ball region, a conical region and a threaded region for installation in ball-and-socket joints. According to said method, a ball journal blank (1) comprising a formed conical region (3) and cylindrical regions for the thread (2) and ball (5) are produced from a rod-shaped semi-finished bar material by extrusion. After the extrusion step, the ball region is subsequently formed by means of a rolling method in an additional production stage. At the same time, the threaded region can be given its final form. The production of the ball journal is thus achieved exclusively by cold forming and permits a significant increase in the production quantity per time unit in comparison with known methods in prior art. More economical types of steel can thus be used, as the cold forming method guarantees the sufficient durability of the ball journal. | ||||||

| 68 | NITINOL BALL BEARING ELEMENT AND PROCESS FOR MAKING | EP00955714.1 | 2000-08-18 | EP1224045A1 | 2002-07-24 | JULIEN, Gerald, J. |
| Bearing elements made of Type 60 Nitinol produced by an investment casting process include providing a ceramic mold (30) having a series of spherical cavities, pouring molten Nitinol into the mold cavities, cooling the mold and the Nitinol in the cavities producing solidified Nitinol balls (40), and breaking the mold away from the Nitinol balls. Nitinol rods (80) for roller bearings can be made by conventional casting. The bars are hot machined or hot rotary swaged and then centerless ground in a ball grinding machine (42) and laser cut to length, or are first cut to length and then centerless ground individually for crowned roller elements. The balls are broken or cut from the risers, leaving the gates attached, and are consolidated by heating under pressure in a hot isostatic press (43), then ground to the desired size. The balls or rollers are polished, treated to create an integral ceramic finish and repolished to produce an extremely smooth finish. | ||||||
| 69 | Stabilizer bar with integral end links for a vehicle suspension system | EP01304093.6 | 2001-05-04 | EP1153775A1 | 2001-11-14 | Keeney, Chris; Yollick, Steve; Clements, Mark; Fader, Joe; Hawkins, Jim |
A suspension system includes a stabilizer bar having an integral ball link directly formed as each end of the stabilizer bar. Because the ball link is integral to the stabilizer bar, there are no bolts, nuts or other fasteners that limit the articulation of the end link relative to the stabilizer bar. The present invention thereby provides greater end link articulation and improved suspension system performance. |

| A method for producing, ball rollers. The following method steps are performed to produce the ball rollers: (A) cutting unfinished sections at a defined length from a round wire that has a defined diameter, (B) compression molding ball roller blanks that have end face depressions in the form of a die tool, and (C) grinding the ball roller blanks to the desired final dimensions in a ball grinding machine. The cut-off unfinished sections have a volume by which during compression molding an approximately tangential raceway transition from one ball roller half to the other ball roller half and material fibers extending under the running surfaces of the ball rollers parallel or approximately parallel to the running surfaces arise. In addition, the ball roller blanks are ground to the final dimensions in a horizontal ball grinding machine loaded exclusively with ball roller blanks of the same size. | ||||||

| A cold forming process for manufacturing ball pivots with a ball area, a cone area and a thread area for installation in ball and socket joints by cold forming is presented, in which a ball pivot blank (1) with a shaped cone area (3) and cylindrical areas for the thread (2) and the ball (5) is manufactured at first from a bar-shaped semifinished bar stock by extrusion. The extrusion operation is followed by the forming of the ball area as another manufacturing step by means of a rolling processes. At the same time, the thread area can be formed in its final shape. Thus, the ball pivot is manufactured as a whole by cold forming only and it makes it possible to significantly increase the production output per unit of time compared to the processes known from the state of the art. At the same time, it is possible to use less expensive grades of steel, because sufficient fatigue strength of the ball pivot can be guaranteed by the cold forming. | ||||||
