Abstract: A method for manufacturing a vehicle wheel is suggested in which the vehicle wheel can provide function and effect of preventing molding defects during molding of an outer rim portion and/or an inner rim portion having sound absorbing spaces 25 and of reducing acoustic cavity noise that occurs in a tire-internal space by use of the sound absorbing spaces. After a separation groove having a curved shape groove bottom surface 55a is formed between a ring-shaped wall portion and partition wall portions, the ring-shaped wall portion is bent toward a flange portion, and the ring-shaped wall portion and the flange portion are welded together. The sound absorbing spaces which communicate with each other via communication gaps defined according to the separation groove are thereby formed in the outer rim portion and/or the inner rim portion. In such a method, since the communication gaps can be stably formed, an increase in internal pressure caused by heat expansion of air in the sound absorbing spaces during a heat treatment step can be reduced, thus allowing prevention of molding defects due to the increase in the internal pressure.

Abstract: The invention relates to a method for suppressing the influence of roll eccentricities on the run-out thickness of a rolled stock, which runs through a rolling stand, roll eccentricities being identified by using a process model and taken into consideration in the determination of a correction signal for a at lest one final control element, preferably a final control element for the adjustment position, of the rolling stand, wherein the measured tensile force upstream of the rolling stand is fed to the process model to identify the roll eccentricities. According to the invention, variations in tensile force are fed back in a targeted manner to reduce the effects of periodic roll eccentricities on the rolled stock, whereas all other sources of variation are eliminated. A process model of the rolling nip and the rolls, preferably based on the observer principle, produces reliable data on the roll eccentricity.

Abstract: A method for producing a bicycle wheel rim is disclosed. The method involves extruding a thin-walled, hollow body having the cross-sectional shape of the rim and an integral external tab. The walls of the hollow body are sufficiently thin that a length of the hollow body without the external tab is subject to buckling when roll formed to produce a rim. The tab is so positioned and sized that the hollow body with the integral external tab is not subject to buckling when roll formed. A portion of the extrusion is then rolled to a circular shape; the circular portion is cut from the extrusion; the free ends are connected, and the external tab is removed.

Abstract: A rolled steel plate 1 wound in a roll shape is unrolled and is cut in given dimensions to form a blank 2. In this case, a cut surface 2a is caused to incline at 1 to 3 degrees relative to the thickness direction of the blank 2, wherein the inclination direction of the cut surfaces 2a, 2a on each side is reversed. The blank 2 cut in this manner is roll-formed to cause the cut surfaces 2a, 2a to confront each other. Since the cut surfaces 2a, 2a on each side incline at 1 to 3 degrees in the opposite direction as described above, the cut surfaces 2a, 2a are caused to be parallel. Then, the confronting sections are laser-welded to form a cylindrical body 3.

The steps include: providing a tube section having a first wall thickness and two end sides; leveling the first wall thickness starting from the two end sides over a defined rotationally-symmetrical area thereby forming two flanks by precontouring, each of the flanks having a second wall thickness, and pushing tolerance-caused excess material of the flanks into a well base zone between the two flanks; and contouring the flanks by pressure rolling while drawing each of the flanks toward an end area of each of the flanks and reducing the thickness of each of the flanks partially differently to predetermined measurements. The present disclosure also includes a device to implement the method.

Abstract: An apparatus and a method for producing a one-part vehicle wheel are provided, in which a substantially disk-shaped, undercut-free pre-form is cast. Immediately after casting the pre-form is conveyed to a flow-forming machine, while maintaining a residual heat and is fixed therein. The circumferential area of the fixed pre-form is split and, by subsequent spinning and flow-forming, is constructed as an intermediate form with a rim, which already substantially has the wall thickness of the rim of the finished vehicle wheel. The intermediate form is cooled, sized, and undergoes a final end-working.
