Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Achse für Fahrradfelgenbremsen, auf der zwei Bügel gelagert sind, welche die Bremsschuhe tragen, und die außerdem zur Befestigung der Felgenbremse an dem Fahrradrahmen dient. Diese Achse ist mit einem Bund (Ring) versehen, der auf der Achse unverrückbar befestigt sein muß.The invention relates to a method of making a Axle for bicycle rim brakes on which two brackets are mounted, which hold the brake shoes wear, and which also serves to attach the rim brake to the bicycle frame. This axle is provided with a collar (ring) which is fixed immovably on the axle have to be.

Die gebräuchlichen Achsen sind meist mit zwei ringsum laufenden Rillen versehen, in welche die innere Wandung des Bundes eingepreßt ist, wodurch ein verhältnismäßig guter Sitz gewährleistet ist. Immerhin ist es schon vielfach vorgekommen, daß ein solcher Bund sich loslöste.The common axes are mostly with two grooves running around them provided, in which the inner wall of the federal government is pressed, making a relatively a good fit is guaranteed. After all, it has often happened that a such covenant broke loose.

Um ein solches Loslösen zu verhindern, hat man bereits versucht, Achse mit Bund aus einer vollen Stange auszudrehen. Diese Herstellungsweise ist aber äußerst kostspielig.In order to prevent such a detachment, attempts have already been made, axis to be twisted out of a full rod with a collar. However, this production method is extreme expensive.

Gegossene Achsen mit Bund kommen wegen großer Unzuverlässigkeit nicht in Frage.Cast axles with a collar do not come because of great unreliability in question.

Nach dem erfindungsgemäßen Verfahren wird die Achse an der Stelle, an welcher der Bund angebracht werden muß, durch spanlose Formung, vorzugsweise durch Stauchen, mit einem Ringwulst versehen, auf den der Bund so aufgepreßt wird, daß der Wulst in dessen Innenwandung eingreift. Dieses Verfahren gewährleistet einen vollkommen sicheren Sitz, ohne daß die Achse geschwächt wird, wie es beim Anbringen von Rillen mit nachfolgendem Einpressen des Bundes der Fall ist.According to the method according to the invention, the axis is at the point to which the collar must be attached, preferably by non-cutting shaping by upsetting, provided with an annular bead onto which the collar is pressed, that the bead engages in the inner wall. This procedure ensures one completely secure fit without weakening the axis, as it is when attaching of grooves with subsequent pressing in of the collar is the case.

Achse und Bund bestehen selbstverständlich aus Metall, vorzugsweise aus Stahl.The axis and collar are of course made of metal, preferably from steel.

Nach einer vorzugsweisen Ausführung des Verfahrens für die Herstellung einer Achse aus Stahl wird der Wulst durch Kaltstauchen erzeugt, der Bund dagegen warm, am besten im rotglühenden Zustand, aufgepreßt.According to a preferred embodiment of the manufacturing process On an axle made of steel, the bead is produced by cold heading, whereas the collar is warm, preferably in a red-hot state, pressed on.

Die nach dem erfindungsgemäßen Verfahren hergestellte Achse für Fahrradfelgenbremsen weist also einen für das Auge unsichtbaren ringsum laufenden Wulst auf, über den der Bund so aufgepreßt ist, daß der Wulst in seine Innenwandung eingreift.The axle for bicycle rim brakes produced by the method according to the invention thus has an all-round bead invisible to the eye, over which the federal government is pressed on so that the bead engages in its inner wall.

Abb. I zeigt schaubildlich eine größtenteils in ihre Bestandteile zerlegte Felgenbremse, Abb. 2 ein Ausführungsbeispiel der neuerungsgemäßen Achse in Seitenansicht und Abb. 3 im Längsschnitt.Fig. I shows a diagram of a large part of its components disassembled rim brake, Fig. 2 an embodiment of the axle according to the innovation in side view and Fig. 3 in longitudinal section.

Auf der Achse I ist der ringsum laufende Wulst 2 angestaucht, über den der Bund 3 aufgepreßt ist.The bead 2 running all around is upset on the axis I, over which the federal government 3 is pressed on.
