Description
Einteilige Tief Bettfelge mit Radschüssel, Stützring oder Stützlappen für luftbereifte Fahrzeugräder Vorliegende Erfindung betrifft eine einteilige Tief bettfelge mit Radschüssel, Stützring oder Stützlappen für luftbereifte Fahrzeugräder.
Die bekannten Felgen dieser Art sind mit der Radschüssel bzw. dem Stützring, auch Adapterring genannt, verschweisst.
Bei den Schweissstellen zwischen Felge und Stütz ring bzw. Radschüssel tritt eine Schwächung ein. Bei unsachgemässer Schweissung oder bei Vorhandensein von Wärmespannungen können von dieser Schweiss stelle ausgehend Dauerbrüche entstehen.
Gegossene Tiefbettfelgen sind bereits bekannt; dieselben sind jedoch aus mehreren Teilen zusam mengesetzt, z. B. aus drei Segmenten. Bei radial un terteilten Felgen bietet die Abdichtung schlauchloser Reifen Schwierigkeiten.
Gemäss vorliegender Erfindung ist die Felge mit radialen Rippen versehen und gemeinsam mit der Radschüssel bzw. dem Stützring bzw. den Stützlappen in einem Stück hergestellt, z. B. durch Giessen oder Pressen.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Es zeigen: Fig. 1 eine Tiefbettfelge mit Stützring im Schnitt und Fig. 2 eine Felge mit angegossener Radschüssel im Schnitt.
Fig. 1 zeigt eine Tiefbettfelge 1, welche zusam men mit dem Stützring 2 ein ungeteiltes Werkstück bildet. Die Versteifungsrippen 3 und 4 verhelfen dieser Felge zu höherer Gestaltfestigkeit und dienen gleichzeitig im Betriebe als Ventilatorflügel, womit sie eine gewisse Luftumwälzung über der Brems trommel gewährleisten.
Fig. 2 zeigt eine Tiefbettfelge 5, welche zusam men mit der Radschüssel 6 ein ungeteiltes Werkstück bildet. Die Versteifungsrippen 7 und 8 verleihen die sem Teil eine grosse Gestaltfestigkeit.
Die Herstellung solcher Felgen kann Beispiels weise durch Giessen oder Pressen erfolgen. Die re lative Schwächung einer solchen Felge durch die Gussstruktur des Materials wird weitgehend kompen siert durch die verstärkende Wirkung der Rippen.
Eine so ausgebildete Felgeneinheit gewährleistet grosse Formfestigkeit, grosse Sicherheit, geringes Ge wicht und gute Kühlung des Reifens und der Brems trommel.
Gegenüber bisher gebauten, gegossenen Felgen haben die beschriebenen Felgen den Vorteil, dass der Reifen auf einer ununterbrochenen Fläche sich ab stützen kann und die Felge höhere Gestaltfestigkeit aufweist. Ein weiterer Vorteil besteht darin, dass diese Felge überhaupt keine Schweissnaht aufweist.
One-piece deep bed rim with wheel disc, support ring or support tab for vehicle wheels with pneumatic tires The present invention relates to a one-piece deep bed rim with wheel disc, support ring or support tab for pneumatic vehicle wheels.
The known rims of this type are welded to the wheel disc or the support ring, also called adapter ring.
At the welding points between the rim and the support ring or wheel disc, a weakening occurs. In the event of improper welding or the presence of thermal stress, fatigue fractures can occur from this welding point.
Cast drop center rims are already known; However, the same are composed of several parts together such. B. from three segments. In the case of radially un subdivided rims, sealing tubeless tires presents difficulties.
According to the present invention, the rim is provided with radial ribs and is made in one piece together with the wheel disc or the support ring or the support tabs, e.g. B. by casting or pressing.
Two exemplary embodiments of the invention are shown in the drawing. The figures show: FIG. 1 a drop center rim with a support ring in section and FIG. 2 a rim with a cast wheel disk in section.
Fig. 1 shows a drop center rim 1, which together with the support ring 2 forms an undivided workpiece. The stiffening ribs 3 and 4 help this rim to a higher structural strength and at the same time serve as a fan blade in operation, thus ensuring a certain air circulation over the brake drum.
Fig. 2 shows a drop center rim 5, which together men with the wheel disc 6 forms an undivided workpiece. The stiffening ribs 7 and 8 give this part a great structural strength.
Such rims can be produced, for example, by casting or pressing. The relative weakening of such a rim by the cast structure of the material is largely compensated for by the reinforcing effect of the ribs.
A rim unit designed in this way ensures great dimensional stability, great safety, low weight and good cooling of the tire and the brake drum.
Compared to previously built, cast rims, the rims described have the advantage that the tire can be supported on an uninterrupted surface and the rim has greater structural strength. Another advantage is that this rim has no weld seam at all.
