Abstract
Description
Die Erfindung bezieht sich auf eine Nabe der dem Oberbegriff des Anspruchs 1 entsprechenden Art.The invention relates to a Hub of the type corresponding to the preamble of claim 1.
Solche Naben sind für Rollstuhlräder in einstückiger Metallausführung bekannt. Sie werden aus einem gegossenen Rohling durch spanabhebende Bearbeitung hergestellt. Es handelt sich um ein relativ großes einstückiges Teil, bei dem der Bearbeitungsaufwand nicht unerheblich ist. Besonders die Anbringung der Lochungen an den beiden einen Abstand voneinander aufweisenden Scheiben ist nicht einfach.Such hubs are known for wheelchair wheels in one-piece metal design. They are made from a cast blank by machining manufactured. It is a relatively large one-piece part, in which the processing effort is not insignificant. Especially the attachment of the perforations The two spaced disks are not easy.
Der Erfindung liegt die Aufgabe zugrunde, die Herstellung einer gattungsgemäßen Nabe wirtschaftlicher zu gestalten.The invention is based, which Production of a generic hub to make it more economical.
Diese Aufgabe wird durch die in Anspruch
1 wiedergegebene Erfindung gelöst.
Die Nabe ist hierbei nicht mehr einstückig, sondern umfasst einen
aus Kunststoff, z.B. glasfaserverstärktem Polyamid geformten eigentlichen
Nabenkörper,
an den zwei Scheiben drehfest angesetzt sind. Die Scheiben können flache
Stanzteile aus Blech sein, bei denen die Lochungen für die Speichen
sogleich mit eingestanzt werden. Das Anbringen der Scheiben geschieht durch
Rufpressen. Die drehfeste Gestaltung ist durch zusammenwirkende
Vorsprünge
und Ausnehmungen erzielt. Eine Nabe dieser Art ist aus der
Da der Nabenkörper ein einfaches Pressteil und die Scheiben flache Stanzlinge sind und die Bremstrommel ein einfaches Blechformteil sein kann, ist die Bearbeitung insgesamt gegenüber der einstückigen Ausführung wesentlich vereinfacht und entsprechend verbilligt.Because the hub body is a simple pressed part and the discs are flat die-cuts and the brake drum is a simple one Can be molded sheet metal, the processing is compared to the total one-piece execution significantly simplified and cheaper accordingly.
Die drehfeste Verbindung der Bremstrommel mit der benachbarten Scheibe kann in der in Anspruch 2 wiedergegeben Weise erfolgen, d. h. in einem nur Sekunden erfordernden Arbeitsgang. Die Bremstrommel kann tiefgezogen sein und bedarf allenfalls an ihrem Innenumfang einer geringfügigen spanenden Bearbeitung.The rotatable connection of the brake drum with the adjacent disc can be reproduced in claim 2 Done way, d. H. in just a few seconds. The brake drum can be deep-drawn and may be required their inner circumference a slight chip removal Processing.
Zweckmäßig weist der Nabenkörper gemäß Anspruch 3 auf der Seite der Bremstrommel einen axialen Bund auf, der sowohl die dortige Scheibe als auch die Bremstrommel in deren zentralen Öffnungen zentrierend durchgreift. The hub body expediently has according to claim 3 on the side of the brake drum on an axial collar that both the disc there as well as the brake drum in its central openings reaches through centering.
Auf diese Weise ist gleichzeitig die Zentrierung der Scheibe gegenüber dem Nabenkörper als auch die Zentrierung der Bremstrommel gegenüber diesem gesichert.This way is simultaneous centering the disc against the hub body as well the centering of the brake drum secured against this.
Im Allgemeinen sind derartige Naben auf zwei in der Nähe der Enden des Nabenkörpers in dessen Innerem angeordneten Kugellagern gelagert. Es empfiehlt sich gemäß Anspruch 4, dass eines dieser Kugellager innerhalb des Bundes angeordnet ist, wodurch eine direkte Übertragung der Kräfte von der das Kugellager durchsetzenden Achse auf die Bremstrommel und insbesondere die Scheibe gegeben ist.Generally such hubs are on two nearby the ends of the hub body ball bearings arranged in its interior. It recommends yourself according to claim 4 that one of these ball bearings is located within the federal government is what makes a direct transfer of forces from the axle passing through the ball bearing to the brake drum and in particular the disc is given.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing, an embodiment of the Invention shown.
