Description

Abfederung für das Hinterrad von Fahrrädern. Die Erfindung bezieht sich auf eine Abfederung für das Hinterrad von Fahrrädern, bei welchen in der Nähe des Tretkurbellagers eine abgefederte schwenkbare Gabel angelenkt ist.Cushioning for the rear wheel of bicycles. The invention relates on a cushioning for the rear wheel of bicycles, which are nearby of the crank bearing a sprung swivel fork is articulated.

Die Erfindung besteht darin, daß die Arme der schwenkbaren Gabel auf jeder Seite des Rades unmittelbar in einer vertikalen Ebene mit den darüberliegenden parallelen und wagerecht verlaufenden Gabelschenkeln des Fahrradrahmens liegen und so je einen Federraum für mehrere gleich starke, nebeneinander angeordnete Druckfedern und für eine am Ende der Gabelarme angebrachte Zugfeder bilden.The invention consists in that the arms of the pivotable fork each side of the wheel immediately in a vertical plane with those above parallel and horizontally extending fork legs of the bicycle frame and one spring space each for several equally strong compression springs arranged next to one another and form for a tension spring attached to the end of the fork arms.

Während bisher bei allen bekanntgewordenen Einrichtungen keine genügende Abfederung, weil nur die Anbringung einer Feder möglich war, entstand oder ein Hin-und Herschleudern des Hinterrades wegen der - beiderseits unabhängigen Federung eintrat, erzielt die neue Erfindung einen genügend großen Federraum zur Anbringung mehrerer Federn, indem die Fahrradstreben in einer Ebene senkrecht übereinanderliegen, bei gleichzeitiger Anwendung schwenkbarer Gabeln, so daß ein seitliches Pendeln des Hinterrades verhütet wird.While so far none of the institutions that have become known has been sufficient Cushioning, because only the attachment of a spring was possible, arose or a back and forth The rear wheel was thrown because of the - both sides independent suspension occurred, the new invention achieves a sufficiently large spring space for attaching several Springs, in that the bicycle struts lie vertically on top of each other in a plane simultaneous use of swiveling forks so that the Rear wheel is prevented.

Die Erfindung läßt sich in verschiedener Weise ausführen. Sie ist in der Zeichnung beispielsweise in einer Ausführungsform veranschaulicht, und zwar zeigt: Abb. i eine Seitenansicht der Hinterr adfederung, .The invention can be carried out in various ways. she is illustrated in the drawing for example in one embodiment, namely shows: Fig. i a side view of the rear suspension,.

Abb. 2 eine Ansicht von hinten, Abb. 3 einen Schnitt nach Linie I-1 der Abb. i.Fig. 2 is a view from the rear, Fig. 3 is a section along line I-1 of fig. i.

Die Radachse a des Hinterrades b ist beiderseits in den Gabelarmen c einer um den Bolzen d schwenkbaren Radgabel e gelagert. Der Anlenkungszapfen d ist in der Nähe des Tretkurbellagers angeordnet. Die so schwenkbare Gabel e bildet zusarnmerr mit dem gabelförmigen Hinterrohr f, das am Sattelrohr g befestigt ist, einen Federraum h, in dem mehrere Schraubenfedern i untergebracht sind. Die Schraubenfedern fassen über Zapfen k, um sie gegen Verschiebung zu sichern.The wheel axle a of the rear wheel b is mounted on both sides in the fork arms c of a wheel fork e pivotable about the bolt d . The pivot pin d is arranged in the vicinity of the pedal crank bearing. The fork e, which can be pivoted in this way, forms, together with the fork-shaped rear tube f, which is fastened to the seat tube g, a spring space h in which several coil springs i are accommodated. The coil springs grasp on pins k to secure them against displacement.

Es findet jetzt eine günstige Abfederung des Hinterrades an den Schraubenfedern statt, ohne daß eine Schrägstellung der Hinterradachse d eintreten könnte.There is now a favorable suspension of the rear wheel on the coil springs instead, without the rear wheel axle d being inclined to occur.

An dem Hinterrohr f ist die gabelförmige Hinterstrebe L angebracht, die nach dem Sattelrohr g führt. Die Gabelarme c der schwenkbaren Gabel e besitzen Verlängerungen m, die an den nach unten gerichteten Führungsschienen n der Gabelarme c geführt sind. Auf beiden Seiten des Rades ist die gleiche Anordnung getroffen. Die Führungsschienen n besitzen Anschläge o, beispielsweise einen herausnehmbaren Zapfen o. dgl., der die Begrenzung für den Anschlag der Gabel e nach unten bildet. An der am weitesten vom Drehbolzen d des Lagerhebels e entfernten Stelle des Federlagerraums lt ist noch eine Zugfeder p eingesetzt, die bei starken Stößen ein stoßartiges Zurückschnellen des Rades verhindert und ein weiches Fahren ermöglicht.The fork-shaped rear strut L, which leads to the seat tube g, is attached to the rear tube f. The fork arms c of the pivotable fork e have extensions m which are guided on the downward guide rails n of the fork arms c. The same arrangement is made on both sides of the wheel. The guide rails n have stops o, for example a removable pin o. The like. Which forms the downward limit for the stop of the fork e. At the point of the spring bearing space lt furthest away from the pivot pin d of the bearing lever e, a tension spring p is also inserted, which prevents the wheel from suddenly snapping back in the event of strong impacts and enables smooth driving.

PATENTANSPRUCH: Abfederung für das Hinterrad von Fahrrädern, bei welchen in der Nähe des Tretkurbellagers eine abgefederte schwenkbare Gabel aasgelenkt ist, dadurch gekennzeichnet, daß die Arme (c) der schwenkbaren Gabel auf jeder Seite des Rades unmittelbar in einer vertikalen Ebene mit den darüberliegenden parallelen und wagerecht verlaufenden Gabelschenkeln (f) des Fahrradrahmens liegen und so je einen Federraum (h) für mehrere gleich starke, nebeneinander angeordnete Druckfedern (i) und für eine am Ende der Gabelarme angebrachte Zugfeder (p) bilden. Claim: suspension for the rear wheel of bicycles in which a sprung pivotable fork is articulated in the vicinity of the pedal crank, characterized in that the arms (c) of the pivotable fork on each side of the wheel are directly in a vertical plane with the parallel and above them horizontally extending fork legs (f) of the bicycle frame and thus each form a spring space (h) for several equally strong, juxtaposed compression springs (i) and for a tension spring (p) attached to the end of the fork arms.
