Abstract
Bremsbelag für eine Scheibenbremse, wenigstens bestehend aus wenigstens einer Schicht mit Metall und/oder metallischen Verbindungen und/oder metallischen Legierungen in Form von Fasern und/oder Partikeln und/oder Faservliesen, dadurch gekennzeichnet, dass die Fasern und/oder Partikel und/oder Faservliese in radialer Richtung einer zugehörigen Bremsscheibe orientiert angeordnet sind.Brake lining for a disc brake, at least consisting of at least one layer with metal and / or metallic compounds and / or metallic alloys in the form of fibers and / or particles and / or fiber webs, characterized in that the fibers and / or particles and / or non-woven fabrics are arranged oriented in the radial direction of an associated brake disc.
Description
Die Erfindung betrifft einen Bremsbelag für eine Scheibenbremse, mindestens bestehend aus Fasermaterial, organischen Bindemitteln und Füllstoffen wie Metall, nach dem Oberbegriff des ersten Anspruchs.The invention relates to a brake pad for a disc brake, at least consisting of fiber material, organic binders and fillers such as metal, according to the preamble of the first claim.
Herkömmliche Bremsbeläge für Scheibenbremsen bestehen aus einer oder mehreren Lagen Fasermaterial mit organischen Bindemitteln und Füllstoffen wie Metall und Gummi.Conventional brake pads for disc brakes consist of one or more layers of fiber material with organic binders and fillers such as metal and rubber.
Bei der Herstellung dieser Bremsbeläge wird üblicherweise zuerst das Material des Bremsbelags, als Pulvergemisch, welches auch metallische Späne enthält, in eine Pressform geschüttet, bevor es unter Druck auf die entsprechend vorbereiteten Trägerplatten gepresst wird. Die Verbindung kann durch spezielle Zwischenschichten verbessert werden. Des Weiteren lassen sich durch Zwischenschichten gezielt Eigenschaften der Bremsbeläge beeinflussen, da sie nicht die gleiche Zusammensetzung wie das Ausgangsmaterial haben.In the production of these brake pads is usually first the material of the brake pad, as a powder mixture, which also contains metallic shavings, poured into a mold before being pressed under pressure on the appropriately prepared carrier plates. The compound can be improved by special intermediate layers. Furthermore, intermediate layers can be used to specifically influence the properties of the brake linings, since they do not have the same composition as the starting material.
Neben mechanischen Eigenschaften ist vor allem die Wärmeleitfähigkeit des Bremsbelags ein wichtiger Parameter, welcher entlang der verschiedenen Raumrichtung verschiedenen Anforderungen unterliegen sollte. In Umfangsrichtung der Bremsscheibe bestehen keine besonderen Anforderungen an die Wärmeleitfähigkeit. In radialer Richtung soll der Bremsbelag eine möglichst gute Wärmeleitfähigkeit aufweisen, um Glühspurbildung und Glühspurwechsel zu vermeiden und in Belagdickenrichtung, normal zur Umfangs- und Radialrichtung, soll eine möglichst geringe Wärmeleitfähigkeit vorliegen, um eine Erwärmung der Bremsflüssigkeit zu verhindern.In addition to mechanical properties, especially the thermal conductivity of the brake pad is an important parameter, which should be subject to different requirements along the different spatial direction. In the circumferential direction of the brake disc, there are no special requirements for the thermal conductivity. In the radial direction of the brake pad should have the best possible thermal conductivity to avoid Glühspurbildung and Glühspurwechsel and in pad thickness direction, normal to the circumferential and radial directions, should have the lowest possible thermal conductivity in order to prevent heating of the brake fluid.
Darüber hinaus besteht die Möglichkeit über alternative Materialzusammensetzungen, beispielsweise durch Zugabe anorganischer silicathaltiger Bindemittel, die mechanischen Eigenschaften und Temperaturbeständigkeit von Bremsbelägen zu verbessern. Weitere Materialkombinationen bei Bremsbelägen sind in der

Der nächstliegende Stand der Technik, die
Durch einen schichtweisen Aufbau von Materialien lassen sich zwar richtungsabhängige Wärmeleitfähigkeiten realisieren, die Herstellung wird jedoch mit jeder neuen Schicht zeit- und kostenaufwändiger und bei Verwendung eines homogenen Materials, also bei nicht schichtweisem Aufbau, kann die Wärmeleitfähigkeit lediglich über eine Veränderung der Materialzusammensetzung realisiert werden.Although direction-dependent thermal conductivities can be realized by layered construction of materials, the production becomes more time-consuming and costly with each new layer, and if a homogeneous material is used, ie if the structure is not layered, the thermal conductivity can only be realized by changing the material composition.
Diesen Zielkonflikt zu lösen, da alle 3 Raumrichtungen von der Änderung der Materialzusammensetzung betroffen sind und einen Bremsbelag bereit zu stellen, der richtungsabhängige Anforderungen an die Wärmeleitfähigkeit erfüllt bei gleichzeitiger preiswerter Herstellungsmöglichkeit ist Aufgabe der Erfindung.To solve this conflict of objectives, since all 3 spatial directions are affected by the change in the composition of materials and to provide a brake pad that meets directional requirements for thermal conductivity while cost-effective production capability is the object of the invention.
Die Aufgabe wird durch die Merkmale des ersten Anspruchs gelöst. Verfahren zur Herstellung solcher Bremsbeläge und weitere Ausbildungen der Erfindung beschreiben die abhängigen Ansprüche.The object is solved by the features of the first claim. Methods for producing such brake pads and other embodiments of the invention describe the dependent claims.
Nach der Erfindung wird vorgeschlagen, die Wärmeleitfähigkeit eines Bremsbelags gemäß richtungsabhängiger Anforderungen zu beeinflussen, indem metallische Späne des Ausgangsmaterials beim Füllen der Pressform radial zur Bremsscheibe ausgerichtet werden.According to the invention, it is proposed to influence the thermal conductivity of a brake pad according to directional requirements by radially aligning metallic chips of the starting material during filling of the mold with the brake disk.
Dies wird realisiert, indem eine Füllvorrichtung zur Füllung einer Pressform ein radiales Gitter besitzt, durch welches die Metallspäne nur bei radialer Orientierung hindurchtreten können. This is realized by a filling device for filling a mold has a radial grid through which the metal chips can pass only in the radial orientation.
Alternativ werden die Metallspäne mit Hilfe eines radialen Magnetfeldes entsprechend ausgerichtet. Das Magnetfeld wird über zwei elektrische Spulen erzeugt, die an der Formfüllvorrichtung oder der Form selbst angebracht sind.Alternatively, the metal chips are aligned with the aid of a radial magnetic field. The magnetic field is generated by two electric coils attached to the mold-filling device or the mold itself.
Eine bevorzugte Ausführung der Erfindung zeigt alternativ eine Kombination aus radialem Gitter und elektrischen Spulen auf, bei der die elektrischen Spulen unmittelbar im Bereich des Gitters angeordnet sind.A preferred embodiment of the invention alternatively shows a combination of radial grid and electric coils, in which the electric coils are arranged directly in the region of the grid.
Nach dem Ausrichten der metallischen Späne, wird das pulverförmige Material des Bremsbelags mit einer Trägerplatte nach bekannten Verfahren des Standes der Technik verbunden.After aligning the metallic chips, the powdery material of the brake lining is connected to a carrier plate according to known methods of the prior art.
Das hat den Vorteil, dass mittels eines preiswerten Herstellungsverfahrens ein Bremsbelag erhalten wird, dessen radiale Ausrichtung von Metallspänen in der Matrix zu richtungsabhängigen Materialeigenschaften des Bremsbelags führt, insbesondere bei der Wärmeleitung.This has the advantage that a brake lining is obtained by means of an inexpensive manufacturing process, the radial orientation of metal chips in the matrix leads to directional material properties of the brake pad, especially in the heat conduction.
