Description

Leichtmetallfelge mit Einlage aus härterem Metall für Fahrräder, Mopeds und andere Fahrzeuge Bei Leichtmetall-Fahrradfelgen werden bei längerem Gebrauch die Sitze der Nippelköpfe, durch welche die Speichen am Felgenbett befestigt sind, ausgeweitet oder angefressen.Light alloy wheel with inlay made of harder metal for bicycles, mopeds and other vehicles Light alloy bicycle rims are used for long periods of time the seats of the nipple heads through which the spokes are attached to the rim bed, enlarged or eaten away.

Ein Nachziehen des Nippels ist dann nur sehr schwer durchführbar oder gar nicht möglich.Retightening the nipple is then very difficult or very difficult not possible at all.

Es ist bereits vorgeschlagen worden, zur Beseitigung dieses Nachteiles ein Stahlband in eine Vertiefung im Felgenbett auf der Schlauchseite oder einfach auf das glatte Felgenbett zu legen ; die beiden Enden des Verstärkungsbandes werden miteinander verschweist was bei dieser Konstruktion erforderlich ist um ein Ablösen des Verstärkungsbandes von der Felge zu verhindern. It has already been proposed to overcome this disadvantage a steel band in a recess in the rim bed on the tube side or simply to lay on the smooth rim bed; the two ends of the reinforcement tape will be welds together what is necessary in this construction for detachment of the reinforcement tape from the rim.

Der erwähnte Vorschlag hat sich nicht durchgesetzt, vermutlich wegen der Herstellungsschwierigkeiten. Es müssen nämlich nicht nur die Enden des vorzugsweise aus rostfreiem Stahl bestehenden Bandes bei einer Temperatur von vielen Hundert OC über dem Schmelzpunkt des Leichtmetalles (üblicherweise werden die Leichtmetallfelgen aus einer Aluminiumlegierung hergestellt), sondern auch die Enden des zu einer Felge gerun- deten Leichtmetallprofilstabes miteinander verschweisst werden.The suggestion mentioned did not prevail, presumably because of the manufacturing difficulties. Not only do the ends of the strip, which is preferably made of stainless steel, have to be at a temperature of many hundreds of OC above the melting point of the light metal (the light metal rims are usually made of an aluminum alloy manufactured), but also the ends of the rounded to form a rim deten light metal profile rods are welded together.

Die vorliegende Erfindung bezieht sich nun auf eine Leichtmetallfelge (vorzugsweise aus Aluminiumlegierung) mit einer Einlage aus härterem Metall (vorzugsweise aus rostfreiem Stahl) im Felgenbett. The present invention now relates to a light alloy rim (preferably made of aluminum alloy) with an insert made of harder metal (preferably stainless steel) in the rim well.

Im Gegensatz zur früher vorgeschlagenen Konstruktion ist das Band aus härterem Metall nicht bloss in eine Vertiefung im Felgenbett auf der Schlauchseite eingelegt, sondern darüber hinaus dadurch in seiner Lage befestigt, dass die Ränder der Vertiefung im Felgenbett hinterschnitten sind und dadurch die Ränder des Bandes festhalten. Dank dieser Konstruktion erübrigt sich das praktisch kaum durchführbare Zusammenschweissen der beiden Enden des Bandes. In contrast to the previously proposed construction, the tape is made of harder metal not just in a recess in the rim well on the tube side inserted, but also secured in its position by the fact that the edges the recess in the rim well are undercut and thereby the edges of the tape hold tight. Thanks to this construction, what is hardly practicable is unnecessary Welding the two ends of the tape together.

Die Figuren 1 bis 6 veranschaulichen ein Verfahren zur Herstellung eines Ausführungsbeispiels der neuerungsgemässen Felge, und zwar mit Stahlband, wobei Stahlband und Felgenprofilstab im Querschnitt gezeigt sind. Figures 1 to 6 illustrate a method of manufacture an embodiment of the rim according to the innovation, with a steel band, the steel strip and the rim profile bar are shown in cross-section.

Das Stahlband 1 gemäss Fig. 1 wird zunächst gewölbt, wie in Fig. 2 dargestellt. Hierauf wird es in die Vertiefung 4 im gewölbten Felgenbett 3 des Leichtmetallprofilstabes 2 so eingelegt, dass seine Ränder 5 unter die Vorsprünge 6 der hinterschnittenen Ränder der Vertiefung 4 zu liegen kommen (Fig. 3. und 4). Es folgt sodann das Niederdrücken des Stahlbandes 1 ; dieses passt sich dabei dem Felgenbett an (Fig. 5). Schliesslich werden die vorspringenden Ränder 6 der Vertiefung 4 auf die Ränder des Stahlbandes heruntergedrückt (Fig. 6). The steel strip 1 according to FIG. 1 is initially arched, as shown in FIG. 2 shown. Then it is in the recess 4 in the curved rim base 3 of the Light metal profile rod 2 inserted so that its edges 5 under the projections 6 of the undercut edges of the recess 4 come to rest (Fig. 3. and 4). The steel strip 1 is then pressed down; this adapts to the Rim well on (Fig. 5). Finally, the protruding edges 6 of the recess 4 pressed down on the edges of the steel band (Fig. 6).

Die Leichtmetallfelge mit Einlage aus härterem Metall muss selbstverständlich dort gepunzt und gelocht werden, wo die Nippelköpfe und das Ventil zu sitzen kommen. The light alloy wheel with inlay made of harder metal must of course hallmarked and punched where the nipple heads and the valve come to sit.
