Description

"Sich selbst einstellende Kugel-Lagerung für Naben- und/oder Tretlager, insbes."Self-adjusting ball bearings for hub and / or bottom brackets, esp.

für Fahrräder".for bicycles ".

Komplette Fahrradnaben oder Tretlager an Fahrrädern od. dgl. sind seit langem bekannt, und zwar insbes. solche mit Kugellagerungeg, wobei die Kugeln einzeln oder in Käfigen gefaßt *~~- eingefügt sind. Diese Kugeln laufen einerseits auf besonderen Lagerflächen der Konen und anFrerseits in Lagerschalen, die in der Nabenhülse beiderseits angeordnet sind, oder ist die Nabenhülse als Lagerschale für die Kugeln ausgebildet.Complete bicycle hubs or bottom brackets on bicycles or the like have been known for a long time, especially those with ball bearings, the balls being held individually or in cages * ~~ - are inserted. These balls run on the one hand on special bearing surfaces of the cones and on the other hand in bearing shells which are arranged in the hub shell on both sides, or the hub shell is designed as a bearing shell for the balls.

In allen Fällen müssen die Konen auf der Achse genauestens eingestellt werden, und zwar so, daß die Kugellagerungen leicht, aber dicht laufen, das Rad selbst die ßpur hält und in der Lagerung sich nur in Drehrichtung bewegen läßt. Hierzu sind die Konen mit Gewinde auf der Achse aufgeschraubt und durch Muttern gekontert. Dies ist jedoch garnicht so einfach, vor allem dann nicht einfach, wenn Nichtfachleute z.B. ein Vorderrad aus einem Fahrrad herausnehmen und wieder einbauen. Hierbei muß mindestens ein Konus genauestens eingestellt werden, wenn das Rad einwandfrei laufen soll.In all cases, the cones on the axis must be precisely set in such a way that the ball bearings run lightly but tightly, the wheel even holds the track and can only be moved in the direction of rotation in the storage. For this purpose, the cones with thread are screwed onto the axle and secured with nuts countered. However, this is not so easy at all, especially not easy when For example, non-specialists can remove a front wheel from a bicycle and reinstall it. At least one cone must be precisely adjusted if the wheel is working properly should run.

Aufgabe vorliegender Erfindung ist eine sich selbst einstellende Kugel-Lagerung für Naben-und/oder Tretlager od. dgl., insbes. für Fahrräder zu schaffen, deren Lösung dadurch gekennzeichnet ist, daß der eine konus auf der an sich bekannten Nabenachse fest und der andere Konus unter Federdruck nach außen strebend verschiebbar gelagert ist.The object of the present invention is a self-adjusting ball bearing for hub and / or bottom bracket od. Like., In particular. For bicycles to create their Solution is characterized in that the one cone on the known per se The hub axle is fixed and the other cone can be displaced striving to the outside under spring pressure is stored.

In weiterer Ausbildung der Erfindung kann der verschiebbare Konus in Verschieberichtung geführt sein, also nicht verdrehbar.In a further embodiment of the invention, the displaceable cone be guided in the direction of displacement, so not rotatable.

Weiterhin hat die Achse nur in ihrem Außenbereich außerhalb der Lagerung Gewinde, z.B.Furthermore, the axle is only in its outer area outside of the storage Thread, e.g.

für die Halterung des Vorderrades in der Vorderradgabel.for holding the front wheel in the front fork.

Darüber hinaus ist die Nabenhülse bauchig ausgebildet und hat im Bereiche ihres stärksten Durchmessers ein oder mehrere Löcher, aus welchen eingedrungene Feuchtigkeit wieder abfließen kann.In addition, the hub shell is bulged and has in the area of their thickest diameter one or more holes from which penetrated Moisture can flow away again.

Die erfindungsgemässe sich selbst einstellende Lagerung hat die sehr bedeutenden Vorteile, daß weder Laie eine solche Lagerung montieren kann.The self-adjusting storage according to the invention has the very significant advantages that neither layperson can assemble such a storage.

db stellt sich äa von selbst genau ein.db adjusts itself exactly by itself.

Wie die Erfindung im einzelnen ausgeführt sein kann, ergibt sich aus der nachfolgenden Beschreibung und der Zeichnung, in der ein Ausführungsbeispiel im Mittellängsschnitt schematisch dargestellt ist.How the invention can be carried out in detail emerges from the following description and the drawing, in which an embodiment is shown schematically in the central longitudinal section.

Auf der Achse 1 ist im Gegensatz zu bisher nur noch in den Aussenbereichen 2 Gewinde aufgebracht. Der einerseitige Konus 3 ist auf der achse 1 fest angeordnet, also weder verdrehnoch verschiebbar. Auf diesem Konus 3 laufen die Kugeln 4 und diese wiederum in der Lagerschalen 5, die in der Nabenhülse 6 eingepresst oder sonstwie mit dieser fest oder lösbar verbunden ist. Der anderseitige Konus 7 ist auf der Achse 1 in Pfeilrichtung 8 verschiebbar angeordnet, und zwar unter Druck 9 stehend, der sich durch eine oder mehrere Federn, Feder scheiben, Gummidistanzrohr 11 od. dgl. bewirgtw ird.In contrast to previously, axis 1 is only in the outdoor areas 2 threads applied. The one-sided cone 3 is fixedly arranged on the axis 1, so neither rotatable nor shiftable. The balls 4 and 4 run on this cone 3 these in turn in the bearing shells 5, which are pressed into the hub sleeve 6 or otherwise is firmly or detachably connected to this. The other side cone 7 is on the Axis 1 arranged to be displaceable in the direction of arrow 8, namely under pressure 9, by one or more springs, spring washers, rubber spacer tube 11 or od. the like.

Auf dem in Pfeilrichtung 9 verschiebbar angeordneten Konus 7 laufen einerseits die Kugeln 12 und diese andererseits in der Lagerschale 13, die wie vorbeschrieben in der Nabenhülse 6 eingepresst oder sonstwie mit dieser verbunden ist.Run on the cone 7, which is arranged displaceably in the direction of arrow 9 on the one hand the balls 12 and these on the other hand in the bearing shell 13, which as described above pressed into the hub shell 6 or otherwise connected to it.

Die lQabenhulse 6 ist beiderseits zu einer Lochscheibe b' ausgebildet, in der die Fahrradspeichen eingehängt werden, sofern die erfindungsgemässe Anordnung bei einem Vorderrad Anwendung findet.The IQabenhulse 6 is formed on both sides to a perforated disk b ', in which the bicycle spokes are hung, provided the arrangement according to the invention applies to a front wheel.

In weiterer Ausbildung ist die Nabenhülse 6 bauchig ausgebildet, d. h. sie hat in ihrem mittleren bereich 14 den stärksten Durchmesser.In a further embodiment, the hub sleeve 6 is bulged, d. H. it has the largest diameter in its central area 14.

Auf diesem stärksten Umfang sind ein oder mehrere Löcher 15 in der habenhülse 6 angeordnet, durch die eingedrungene Feuchtigkeit åederzeit abfließen kann bzw. herausgeschleudert wird.On this strongest circumference there are one or more holes 15 in the have arranged sleeve 6 through which any moisture that has penetrated can flow away at any time can or is thrown out.

Es ist damit nicht mehr moglich, daß Feuchtigkeit in den Lagerungen verbleibt und dort #### t;>-rungen bewirkt, wie dies hier sehr oft der Fall war.It is no longer possible that moisture in the bearings remains and there #### t;> - causes, as was very often the case here.

Die iseuerung ist nicht auf die dargesteilten Einzelheiten beschrankt, vielmehr auch abgeändert ausfuhrbar, sofern nur die Erfingungsmerkmale zum ausdruck kommen.The change is not limited to the details presented, rather, they can also be executed in modified form, provided that only the features of the invention can be expressed come.
