Description
Die- Erfindung betrifft eine Bremse, insbesondere Zweibäckenbremsre für' Kraftfahrzeuge, mit- einer doppelt gelagerten Bremswelle, die am einen Ende den Spreiznocken für die Bremsbacken und- am anderen Endeden Bremshebel trägt, Diese Bremsen haben bekanntlich den Nachteil ungleicher Abnutzung: der Bremsbeläge. Zum Ausgleich hierfür ist es bereits üblich, -die Beläge ungleich groß zu machen und auch die Spreizkräfte durch eine besondere Form des Spreiznockens den Erfordernissen anzupassen. Dennoch ist der Ausgleich nur unvollkommen. Die Erfindung hat zur Aufgabe; die unvermeidlichen Unterschiede selbsttätig auszugleichen. Ein wesentliches Merkmal der Erfindung besteht darin, d,aß die nockenseitige Lagerung der Bremswelle nachgiebig ist: Dadurch können sich die Bremsbacken, im wesentlichen ungehindert durch die Bremswelle, innerhalb der Trommel einstellen.The invention relates to a brake, in particular two-jaw brake for 'motor vehicles, with a double-bearing brake shaft at one end the expansion cam for the brake shoes and - at the other end the brake lever, these It is well known that brakes have the disadvantage of uneven wear: the brake pads. To the To compensate for this, it is already common practice to make the coverings unequal and the expansion forces also meet the requirements through a special form of the expansion cam adapt. However, the balance is only imperfect. The invention has for its object; automatically compensate for the inevitable differences. An essential feature of the invention is that the cam-side mounting of the brake shaft is resilient is: This allows the brake shoes, essentially unhindered by the Adjust the brake shaft inside the drum.
Gemäß einer bevorzugten.Ausführungs.form der. Erfindung besteht das nachgiebige Lager -der Bremswelle aus einer die Welle,umgebenden Büchse aus nachgiebigem, vorzugsweise federnd nachgiebigem Stoff, wie Gummi, wobei die Büchse vorzugsweise gegen Drehung gesichert im Bremsdeckel sitzt.According to a preferred embodiment of the. Invention exists compliant bearing - the brake shaft from a sleeve surrounding the shaft made of flexible, preferably resilient material, such as rubber, with the sleeve preferably is secured against rotation in the brake cover.
Gemäfß einem weiteren Merkmal der Erfindung ist die nachgiebige Büchse mit einer Lagerhülse ausgelegt, die bei Verwendung von Gummi einvulkanisiert ist.According to a further feature of the invention is the resilient sleeve designed with a bearing sleeve that is vulcanized in when using rubber.
Weitere # Einzelheiten der Erfindung ergeben sich aus der folgenden Beschreibung, die die Erfindung am Beispiel einer einfach wirkenden Zweibacken-@breInse für Kraftfahrzeuge erläutert.Further details of the invention emerge from the following Description that the invention using the example of a single-acting two-jaw @ breInse explained for motor vehicles.
'Die je einen Bremsbelag tragenden Bremsbacken sitzen üblicherweise drehbar auf je.einem in der Trägerplatte verankerten Bolzen. Rückholfedern drücken die freien Enden der Bremsbacken gegen den Spreiznocken, der. auf dem- Ende der -Bremswelle sitzt. Die Bremswelle ist einerseits in der Trägerplatte und andererseits im Fahrzeuggestell drehbar gelagert. Das dem Spreiznocken entgegengesetzte Ende der Bremswelle - trägt den Bremshebel, an den das Zugorgan angeschlossen ist.The brake shoes, each carrying a brake lining, are usually seated rotatable on a bolt anchored in the carrier plate. Press the return springs the free ends of the brake shoes against the expansion cam, the. at the end of the -Brake shaft is seated. The brake shaft is on the one hand in the carrier plate and on the other hand rotatably mounted in the vehicle frame. The end opposite the expansion cam the brake shaft - carries the brake lever to which the pulling element is connected.
Erfindungsgemäß ist das nockenseitige Lager der Bremswelle nachgiebig ausgebildet, so @daß der Bremshebel in diesem Lager seitlich ausweichen kann, um ungleiche Bremsbela@gabnutzung der beiden Bremsbacken au iazugleichen. Das bremshebelseitige Lager der Bremswelle besitzt genügend Spiel, um eine geringe Schrägstellung der Bremswelle zu gestatten. Das Lager kann bei Spielfreiheit auch ballig ausgebildet sein. In der Zeichnung ist ein Ausführungsbeispiel eines nachgiebigen Lagers der -Bremswelle dargestellt, und zwar zeigt Fig. i das Lager im Axialschnitt und Fig.2 einen Teilschnitt gemäß Linie II-II der Fig. i.According to the invention, the cam-side bearing of the brake shaft is flexible designed so @ that the brake lever can move laterally in this camp to unequal brake pad use of the two brake shoes. The brake lever side The bearing of the brake shaft has enough play to prevent the Allow brake shaft. The bearing can also be convex if there is no play be. In the drawing, an embodiment of a compliant bearing is the -Brake shaft shown, namely Fig. I shows the bearing in axial section and Fig.2 a partial section along line II-II of Fig. i.
Das nockenseitige Lager .der Bremswelle @i besitzt eine die Welle umgebende Büchse 2 aus nachgiebigem Stoff, wie Gummi. In die Büchse ist eine aus einem Stück Messingrohr bestehende Lagerhülse 3 eingelassen, vorzugsweise einvulkanisiert. Die Büchse ist in einer Nabe der Trälgerplatte q. gelagert. Um idlie Büchse gegen Drehung zu sichern, besitzt sie beispielsweise am Rand Vorsprünge 5 oder durchgehende Rippen, die in entsprechende Aussparungen der Trägerplatte eingreifen: Durch eine Bohrung 6 läßt sich das Lager schmieren. Die Büchse 2 überragt die Hülse 3 beidendig. Die überragenden Abschnitte liegen an der Bremswelle zum "!.'weck der Abdichtung an.The bearing on the cam side of the brake shaft @i has a shaft surrounding sleeve 2 made of flexible material, such as rubber. There's one in the box a piece of brass tube existing bearing sleeve 3 let in, preferably vulcanized. The bushing is in a hub of the carrier plate q. stored. To idlie rifle against To secure rotation, it has, for example, at the edge projections 5 or continuous Ribs that engage in corresponding recesses in the carrier plate: Through a Bore 6 can be used to lubricate the bearing. The sleeve 2 projects beyond the sleeve 3 at both ends. The protruding sections are on the brake shaft to "!." Wake up the seal at.
Die Erfindung ist nicht auf das beschriebene Ausführungsbeispiel beschränkt. Die Nachgiebigkeit des Lagers könnte auch auf ändere Weise erzielt werden, beispielsweise durch ein von der Bremswelle durchsetztes und am Deckel gelagertes nachgiebig befestigtes Gleitstück:The invention is not restricted to the exemplary embodiment described. The compliance of the bearing could also be achieved in other ways, for example by a resiliently attached one penetrated by the brake shaft and mounted on the cover Slider:
