Reibringe von Schienenfahrzeugen bestehen im Allgemeinen aus einem homogenen Werkstoff, z. B. aus Schmiedestahl, Stahlguß, Kugelgraphitguß, Grauguß oder Aluminium. Aluminium-Reibringe werden heute aus einer Keramikpartikel verstärkten Aluminiumlegierung mittels Gießverfahren hergestellt.friction rings rail vehicles generally consist of a homogeneous one Material, eg. B. from forged steel, cast steel, nodular cast iron, Gray cast iron or aluminum. Aluminum friction rings become today Made of a ceramic particle reinforced aluminum alloy produced by casting.
Um die Lebensdauer einer Bremsscheibe zu erhöhen, wäre es wünschenswert, die Verschleißschicht aus einem Werkstoff darzustellen, der verschleißfester als der kostengünstige Tragkörperwerkstoff ist.Around to increase the life of a brake disc would be it is desirable to remove the wear layer from one Represent material, the more wear-resistant than the cost-effective Supporting material is.
Folgende Verfahren sind hierzu bekannt:
- – Plasmaspritzen im Vakuum
- – 3-Schichtgießen
- – Heißisostatisches Pressen einer aufgebrachten Pulverschicht (HIP-Verfahren).
- - Plasma spraying in vacuum
- - 3-layer casting
- - Hot isostatic pressing an applied powder layer (HIP method).
Zur Kostenreduzierung wurden bisher zwei Alternativlösungen untersucht bzw. entwickelt.to Cost reduction has so far been two alternative solutions examined or developed.
Die
erste Lösung besteht in einem Mehrschichtgießverfahren,
wie es im Patent
Die zweite Alternativlösung ist das heißisostatische Pressen (HIP), bei dem unter Anwendung hoher Temperaturen, die kleiner als die Materialschmelztemperatur ist, und einer isostatischen Druckbeaufschlagung von mehreren Hundert MPa pulverförmige oder poröse Werkstoffe gleichmäßig verdichtet werden.The second alternative solution is the hot isostatic Pressing (HIP), in which under application of high temperatures, the smaller is the material melt temperature, and isostatic pressurization of several hundred MPa powdery or porous Materials are compressed evenly.
Das Plasmaspritzverfahren ist unwirtschaftlich und erlaubt nur das Aufbringen dünner Schichten. Dieses Verfahren wird deshalb nicht auf die Herstellung von Bremsscheiben verwendet.The Plasma spraying is uneconomical and allows only the application thin layers. This method is therefore not on used the manufacture of brake discs.
Die beiden anderen Verfahren ergeben unter Laborbedingungen gute Ergebnisse. Sie werden aber nicht in der Produktion eingesetzt, da sie nicht ausreichend prozeßsicher sind oder der Aufwand für die Qualitätssicherung unwirtschaftlich hoch ist.The both other methods give good results under laboratory conditions. They are not used in production because they are not sufficient are process-safe or the effort for quality assurance uneconomically high.
Der Erfindung liegt die Aufgabe zugrunde, eine Bremsscheibe sowie ein Verfahren zur Herstellung einer Bremsscheibe der gattungsgemäßen Art zu entwickeln, die die oben genannten Nachteile beseitigt und eine kostengünstige und prozeßsichere Herstellung von Bremsscheiben gewährleistet.Of the Invention is based on the object, a brake disc and a Method for producing a brake disk of the generic type To develop kind, which eliminates the above-mentioned disadvantages and a cost-effective and reliable production guaranteed by brake discs.
Diese Aufgabe wird durch eine Bremsscheibe mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 und einem Verfahren zur Herstellung einer Bremsscheibe mit den Merkmalen des kennzeichnenden Teils des Anspruchs 7 gelöst.These Task is characterized by a brake disc with the characteristics of the characterizing Part of claim 1 and a method for producing a Brake disc having the features of the characterizing part of the claim 7 solved.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen genannt.advantageous Embodiments are mentioned in the subclaims.
Das erfindungsgemäße Verfahren ist insbesondere im Vergleich zum HIP-Verfahren eine sehr kostengünstige Beschichtungsart. Auch die Prozeßsicherheit wird durch das erfindungsgemäße Verfahren, verglichen mit dem HIP- oder Schichtgießverfahren, erhöht.The inventive method is particularly in Compared to the HIP process, a very inexpensive type of coating. The process reliability is achieved by the invention Method, compared to the HIP or layer casting method, elevated.
Insbesondere ist das Verfahren auf alle Reibringgrundwerkstoffe anwendbar, so z. B. auf Grauguß, Stahlguß, Schmiedestahl, Kugelgraphitguß oder Aluminium.Especially if the method is applicable to all friction ring base materials, then z. B. on gray cast iron, cast steel, forged steel, nodular cast iron or Aluminum.
Außerdem kann unter verschiedenen verschleißreduzierenden Materialien wie beispielsweise SiC, Al2O3 oder Hartmetallpulver ausgewählt werden.In addition, among various wear-reducing materials such as SiC, Al 2 O 3 or hard metal powder can be selected.
Auch sind Kombinationen von Metallen möglich, die sich nicht durch Schmelzen mischen lassen.Also Combinations of metals are possible that are not mix by melting.
Als
Verstärkungskomponenten sind möglich:
Oxide,
Karbide, Nitride, Boride und Reinelemente wie C und Si.As reinforcing components are possible:
Oxides, carbides, nitrides, borides and pure elements such as C and Si.
Verfahrensbedingt sind überdies beliebige Verschleißschichtdicken erzeugbar.Due process are also any wear layer thicknesses produced.
Desweiteren ist eine geringere Nachbearbeitung notwendig, da nur geringe Bearbeitungsaufmaße erforderlich sind.Furthermore a lower level of post-processing is necessary as only small machining allowances required are.
Als Reibbeschichtung auf Stahl- oder Graugußreibringen können Metalle mit sehr hoher Wärmeleitungsfähigkeit (z. B. Kupfer) oder geringen Wärmeausdehnungskoeffizienten verwendet werden, wodurch die Rißgefahr merklich reduziert werden kann, oder es können Metall- oder Keramikpartikel mit geringerem spezifischen Verschleiß als dem des Grundwerkstoffes aufgetragen werden.As a friction coating on steel or gray cast iron friction rings metals with very high thermal conductivity (eg copper) or low coefficients of thermal expansion can be used, whereby the risk of cracking can be significantly reduced, or it can metal or ceramic particles be applied with less specific wear than that of the base material.
Das Verfahren ist insbesondere für Bremsscheiben für Schienenfahrzeuge geeignet. Es ist aber auch für Nutzfahrzeugbremsscheiben anwendbar, da es, bedingt durch die großen Stückzahlen, auch in diesem Bereich sehr kostengünstig ist.The Method is especially for brake discs for Rail vehicles suitable. But it is also for commercial vehicle brake discs applicable, because it, due to the large quantities, too very cost effective in this area.
Ein Ausführungsbeispiel wird nachfolgend anhand der beigefügten Zeichnungen beschrieben. Es zeigen:One Embodiment will be described below with reference to the attached Drawings described. Show it:
Die
prinzipielle Anordnung zur Herstellung einer Bremsscheibe mit Hilfe
des Sprühkompaktierverfahrens ist in
Als Sprühkompaktieren bezeichnet man ein Verfahren, das aus der Verdüsung einer metallischen Schmelze und der Abscheidung der erstarrenden Tröpfchen auf einem Substrat besteht.When Spray compacting is the name given to a process that consists of the atomization of a metallic melt and the deposition the solidifying droplets on a substrate.
Zur Herstellung einer Bremsscheibe mit diesem Verfahren wird zuerst ein Bremsscheibentragkörper gegossen und vorbearbeitet.to Making a brake disc with this procedure will be first a brake disk carrying body is poured and preprocessed.
Dieser Tragkörper kann aus Aluminium oder einer Aluminiumlegierung, aus Grauguß, Stahlguß, Schmiedestahl oder Kugelgraphitguß bestehen.This Supporting body may be made of aluminum or an aluminum alloy, cast iron, cast steel, forged steel or nodular cast iron.
Bei der Vorbearbeitung wird die während des Gießvorgangs entstandene Oxidschicht auf der zu kontaktierenden Tragkörperoberfläche mechanisch oder mit einem sonstigen Verfahren entfernt. Danach wird der Tragkörper vorgewärmt, um die Haftung der darauf aufzubringenden Reibbeschichtung zu erhöhen und um Eigenspannungen nach dem Abkühlen zu minimieren.at The pre-processing is done during the casting process resulting oxide layer on the contact surface to be contacted removed mechanically or by another method. After that will the support body preheated to the adhesion of it To increase applied friction coating and to residual stresses to minimize after cooling.
Fertigungsablauf (prinzipiell):Production process (in principle):
Das
Depostimaterial (z. B. Aluminiumlegierung) für die Reibbeschichtung
wird in einem Tiegel
Gleichzeitig werden von einer zweiten Düse Hartpartikel (z. B. Keramikpulver) in den Metallschmelzensprühstrahl geblasen.simultaneously are hard particles (eg ceramic powder) from a second nozzle blown into the molten metal spray.
Die beiden Komponenten treffen unter hohen Geschwindigkeiten auf der zu beschichtenden Oberfläche des Bremsscheibentragkörpers auf und verbinden sich mit dieser. Das Aufsprühen der beiden Komponenten auf den Tragkörper wird so lange durchgeführt, bis die gewünschte Reibbelagdicke erreicht ist.The both components meet at high speeds on the to be coated surface of the brake disk carrying body up and connect with this. Spraying the two components on the support body is carried out so long until the desired friction lining thickness is reached.
Abhängig von den Prozeßparametern läßt sich so eine dichte Schicht aus Komponenten herstellen, die sich nicht legieren lassen, aber als Reibbeschichtung die gewünschten Eigenschaften hinsichtlich Verschleißfestigkeit, Wärmeleitvermögen oder Rißfestigkeit aufweisen.Dependent of the process parameters can be so make a dense layer of non-alloy components let, but as a friction coating the desired properties in terms of wear resistance, thermal conductivity or Have crack resistance.
Die Reibbeschichtung besteht damit aus einer Mischung aus metallischem Werkstoff und Keramikpartikeln. Die verschleißreduzierenden Partikel bestehen bevorzugt aus SiC, können aber auch aus Al2O3 oder anderen keramischen oder metallischen Hartwerkstoffen bestehen.The friction coating thus consists of a mixture of metallic material and ceramic particles. The wear-reducing particles are preferably made of SiC, but may also consist of Al 2 O 3 or other ceramic or metallic hard materials.
In
die Verschleißschicht bzw. Reibbschichtung
Die Verschleißschicht bzw. Reibbeschichtung ist vorzugsweise zwischen 2 und 5 mm dick (je nach Einsatzfall).The Wear layer or friction coating is preferably between 2 and 5 mm thick (depending on the application).
Die bevorzugte Keramik-Partikelgröße beträgt 10 bis 40 mm.The preferred ceramic particle size is 10 to 40 mm.
Die
Reibbeschichtung
Zu diesem Zweck werden die Massenströme aus den Sprühdüsen entsprechend seitlich verändert. Beispielsweise kann dadurch die Hartpartikelkonzentration an der Reiboberfläche höher sein als in der Nähe des Tragkörpers.To For this purpose, the mass flows from the spray nozzles changed accordingly laterally. For example, it can the hard particle concentration at the friction surface higher be as near the supporting body.
Allmähliche Änderungen der Werkstoffeigenschaften, vor allem im Bereich des Überganges zum Grundkörper wirken sich meist günstig in bezug auf Wärmespannungen aus, vor allem dann, wenn Reibbeschichtung und Tragwerkstoff unterschiedliche Wärmeausdehnungskoeffizienten aufweisen.Gradual changes the material properties, especially in the area of the transition to the main body usually have a favorable effect in terms to thermal stresses, especially if friction coating and bearing material different thermal expansion coefficients exhibit.
