Abstract
Description
Durch das Hauptpatent ist ein mit Hohlspeichen ausgerüstetes Leichtmetall-Gußrad für Kraftfahrzeuge unter Schutz gestellt, bei dem die vom Tiefbett der Felge aus zum Radzentrum reichenden Hohlspeichen zum Reifeninnenraum hin offen ausgebildet sind.The main patent means that it is equipped with hollow spokes Light alloy cast wheel for motor vehicles under protection, in which the From the drop center of the rim to the hollow spokes reaching the wheel center are open towards the tire interior.
Diese Maßnahme bewirkt, daß das zur Radfederung dienende, verdichtete Reifenvolumen vergrößert und der Reifen schmäler ausgebildet werden kann, wodurch die Lauffläche verkleinert, der Reibschluß mit der Fahrbahn verbessert, und der Reifenabrieb sowie das Ablaufgeräusch vermindert werden.This measure has the effect that the wheel suspension compressed tire volume increases and the tire narrower can be formed, thereby reducing the tread, the Friction with the road improved, and tire wear and that Drain noise can be reduced.
Außerdem wird der durch Breitreifen verursachte Widerstand beim Abrollen verringert, somit Brennstoff eingespart.In addition, the resistance caused by wide tires at Unrolling reduced, thus saving fuel.
Diese Vorteile zu vergrößern und dazu den Radkörper aerodynamisch günstiger zu gestalten, hat sich die Erfindung zur Aufgabe gesetzt. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs gelöst.These advantages increase and the aerodynamic wheel body To make it cheaper, the invention has set itself the task. These Task is characterized by the characterizing features of the claim solved.
In den Abbildungen ist ein Ausführungsbeispiel der Erfindung dargestellt. In Fig. 1 ist eine Radhälfte in der Außenansicht, bei der die zusammen mit der Rückwand 4 und der Radschale 5 sitzenden, die mit dem Reifeninnenraum 1₁ verbundenen Innenräume 2 bildenden Rippen 3 gestrichelt angegeben sind.An embodiment of the invention is shown in the figures. In Fig. 1 is a wheel half in the external view, in which the seated together with the rear wall 4 and the wheel shell 5 , the interior 2 forming with the tire interior 1 ₁ forming ribs 3 are shown in dashed lines.
Beim Gießen des Radkörpers werden die Speicheninnenräume 2 durch in der Gußkokille ausfahrbar angeordnete Kerne erzeugt, welche mit 8 gekennzeichnet sind.When the wheel body is cast, the spoke interiors 2 are produced by cores which are arranged so as to be extendable in the casting mold and which are identified by 8 .
Im Querschnitt Fig. 3 ist die Queransicht eines Gußkerns 8 gestrichelt angegeben. Bei diesem Schnitt ist ebenso wie beim Querschnitt Fig. 2 die übrige Gestaltung des Radkörpers veranschaulicht. In cross section Fig. 3, the transverse view of a cast core 8 is shown in dashed lines. In this section, as with the cross section in FIG. 2, the remaining design of the wheel body is illustrated.
Mit 5 ist in diesen Figuren die Radschale, welche das Felgenhorn 6 trägt, sowie die Rückwand 4, welche die Hohlräume zum Radinneren hin begrenzt, verdeutlicht. In zylindrischer Fortsetzung 4₁ umschließt die Rückwand den Bremsenraum des Rades und trägt am Außenrand das Felgenhorn 7.With 5 in these figures, the wheel well, which carries the rim flange 6 , and the rear wall 4 , which delimits the cavities towards the wheel interior, are illustrated. In a cylindrical continuation 4 ₁, the rear wall encloses the brake chamber of the wheel and carries the rim flange 7 on the outer edge.
Das Gußrad ist mittels Radschrauben 9 mit der Nabe 10 der Achse verbunden. Bei dem dargestellten Ausführungsbeispiel sind sechs Radschrauben vorgesehen, wodurch insgesamt zwölf in der Kokille verschiebbare Kerne erforderlich sind. Bei vier Radschrauben entstehen acht Innenräume, welche durch Kerne erzeugt werden.The cast wheel is connected to the hub 10 of the axle by means of wheel bolts 9 . In the illustrated embodiment, six wheel bolts are provided, which means that a total of twelve cores which can be displaced in the mold are required. With four wheel bolts, eight interior spaces are created, which are created by cores.
Die Vorteile der Lösung der am Umfang nebeneinander angeordneten, mit dem Reifeninnenraum verbundenen Hohlräume gegenüber der Lösung mit Einzelspeichen und darin befindlichen, den Reifeninnenraum vergrößernden Lufträumen besteht darin, daß bei gleichem Aufwand ein größerer Luftraum zur Verfügung steht, das Rad durch seine glatte Radschale 5 aerodynamische Vorteile aufweist, und leichter ist.The advantages of the solution of the cavities arranged next to one another on the circumference, connected to the tire interior, compared to the solution with individual spokes and air spaces which increase the tire interior therein, are that, with the same effort, a larger air space is available, the wheel is aerodynamic due to its smooth wheel shell 5 Has advantages, and is easier.
