Description
Die Erfindung bezieht sich auf eine Felge für Fahrräder und Motorräder.The invention relates to a rim for bicycles and motorcycles.
Derzeit sind die meisten Fahrräder mit Wulstreifen versehen. Die Entwicklung von wenig brüchigen und leicht zu reparierenden Reifen führt außer beim Wettkampfsport immer mehr zur Verwendung dieses Reifentyps. Diese Reifen werden auf besondere Felgen aufgeklebt, die zur Montage üblicher Reifen nicht verwendbar sind. Diese Forderung behindert die Entwicklung der neuen, zuvor erwähnten Reifentypen, da der Benutzer beim Übergang von einem üblichen Wulstreifen auf solch einen schlauchlosen Reifen einen neuen Satz Felgen kaufen muß.Most bicycles currently have flaps. The development of little fragile and easy to repairing tires leads to the use of this type of tire more and more besides in competitive sports. These tires are glued to special rims that cannot be used for mounting conventional tires. This requirement hampers the development of the new types of tires mentioned above, as the user makes the transition having to buy a new set of rims from an ordinary tire tire on such a tubeless tire.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Felge zu schaffen, die zur Aufnahme von Wulstreifen und schlauchlosen Reifen geeignet ist.The invention is therefore based on the object of creating a rim that can accommodate bead strips and tubeless tires.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved according to the invention by what is specified in the characterizing part of claim 1 Characteristics. Appropriate refinements of the invention emerge from the subclaims.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels erläutert, das einen Querschnitt eines Felgenprofils zeigt.The invention is explained below using an exemplary embodiment which has a cross section of a rim profile shows.
030065/0751030065/0751
Wie die Zeichnung zeigt, hat das Felgenprofil drei Flächen 10, 1O1 und 12 zum Aufkleben eines strichpunktiert gezeigten Reifens B. Es wurde festgestellt, daß es unabhängig von der Form des auf der Felge angeordneten Reifens notwendig ist, daß die Länge, gemessen auf dem geraden Profilabschnitt, der Flächen 10, 101 und 12 zum Aufkleben des Reifens wenigstens etwa 1 cm (1 + I1 + 1" = 1 cm) betragen muß.As the drawing shows, the rim profile has three surfaces 10, 1O 1 and 12 for gluing on a tire B. straight profile section, the surfaces 10, 10 1 and 12 for gluing the tire must be at least about 1 cm (1 + I 1 + 1 "= 1 cm).
Die Felge hat außerdem Ausnehmungen zur Aufnahme der Wülste eines üblichen Reifens. In der Zeichnung sind bei T in unterbrochenen Linien Wülste eines üblichen Reifens gezeigt. The rim also has recesses for receiving the beads of a conventional tire. In the drawing are at T in broken lines show beads of a conventional tire.
Es sind zwei Arten von Ausnehmungen vorhanden:There are two types of recesses:
1. Innere Ausnehmungen 18, 18' zur vorläufigen Aufnahme der Wülste während der Montage eines Reifens auf der Felge, und1. Inner recesses 18, 18 'for the preliminary inclusion of the Beads on the rim during the assembly of a tire, and
2. Umfangsausnehmungen 16, 16', in denen die Wülste bei der Endmontage des Reifens angeordnet werden.2. Circumferential recesses 16, 16 'in which the beads at the final assembly of the tire.
Die Felge hat in der Mitte einen relativ massiven Teil 14, der für das Anbringen der Radspeichenenden durchbohrt werden kann. Auf diese Weise wird der Herstellungspreis gegenüber üblichen Felgen verringert, bei denen es notwendig ist, die Felge zu durchbohren und ösen komplizierter Form für das Anbringen der Speichen vorzusehen.The rim has a relatively massive part 14 in the middle which pierces for the attachment of the wheel spoke ends can be. In this way, the manufacturing price is reduced compared to conventional rims, where it is necessary is to drill through the rim and provide loops of a complicated shape for attaching the spokes.
Das Felgenprofil kann wirtschaftlich hergestellt werden, Reifen, insbesondere der neuen Art, wie sie derzeit entwickelt werden, die wenig brüchig und leicht zu reparieren sind, und übliche Wulstreifen aufnehmen.The rim profile can be manufactured economically, tires, especially of the new type as they are currently being developed that are not very brittle and easy to repair, and take up conventional tire strips.
Die Felge kann aus beliebigem Material hergestellt werden. Sie kann aus verstärktem Kunststoffmaterial oder aus einer Leichtmetall-Legierung hergestellt werden. In letzterem Fall kann das Profil durch Extrusion und nachfolgendes Biegen und Verschweißen der Enden hergestellt werden.The rim can be made of any material. It can be made from reinforced plastic material or from a Light metal alloy can be produced. In the latter case, the profile can be made by extrusion and subsequent bending and welding the ends together.
