Abstract
Description
Die Neuerung betrifft einen Reibbelag als Brems- oder Kupplungsbelag für Straßen- und Schienenfahrzeuge sowie für industrielle Anwendungen, bestehend aus einer Trägerplatte mit aufgebrachtem Reibmaterial, wobei die Trägerplatte auf der reibmaterialtragenden Seite ein strukturiertes Halterungsbett aus kraft- und formschlüssigen Elementen aufweist sowie Verfahren zur Herstellung solcher Trägerplatten.The innovation concerns a friction lining as a brake or clutch lining for Road and rail vehicles also for industrial applications, consisting of a carrier plate with applied friction material, being the backing plate a structured mounting bed on the friction material bearing side from positive and form-fitting Has elements and methods for producing such carrier plates.
- 1. Es ist bekannt, bei der Herstellung von Reibbelägen den Schichtenverbund zwischen Reibmaterial und Trägerplatte mittels eines Klebers auf organischer Basis herbeizuführen. Klebstoffe auf organischer Basis weisen jedoch Stabilitätsgrenzen während der Belastung in Reibbelägen vorkommenden Temperaturen auf. Insbesondere beginnt oberhalb ca. 300° C eine Zersetzung der polymeren Bestandteile des organischen Klebers, die zu einer Zerstörung der ursprünglichen Klebeverbindung und damit zu einer Schwächung der Bindung zwischen Reibmaterial und Trägerplatte führen kann. In solchen Fällen ist ein sicheres Funktionieren des Reibbelages nicht mehr gegeben.1. It is known in the manufacture of friction linings the layered bond between the friction material and the carrier plate by means of an organic-based adhesive. adhesives on an organic basis, however, there are stability limits that occur in friction linings during loading Temperatures on. In particular, decomposition begins above approx. 300 ° C of the polymeric constituents of the organic adhesive, which lead to a destruction the original Adhesive connection and thus weakening the bond between Friction material and carrier plate to lead can. In such cases there is no longer a safe functioning of the friction lining.
- 2. Es ist bekannt, dass bei der Herstellung von Reibbelägen Trägerplatten mit Bohrungen, Vertiefungen oder Sicken verwendet werden, in denen das Reibmaterial durch hineinpressen mechanisch verankert wird. Wird ein Reibbelag höher belastet, so können die dabei auftretenden Temperaturen zu einer Schwächung der Bindung durch unterschiedliche spezifische Wärmeausdehnungen führen. Als Folge daraus lockert sich die ursprüngliche Verankerung des Reibmaterials auf der Trägerplatte, und es besteht die Gefahr der Ablösung.2. It is known that in the manufacture of friction linings carrier plates can be used with holes, depressions or beads in which the Friction material is mechanically anchored by pressing it in. Becomes one friction lining higher burdened, so can the temperatures that occur thereby weaken the Binding through different specific thermal expansions. As a result this loosens the original one Anchoring the friction material on the carrier plate, and there is the Risk of detachment.

Der im Patentanspruch angegebenen Erfindung liegt das Problem von Reibbelägen zugrunde, dass diese nicht unter allen Einsatzbedingungen und über den gesamten Zeitraum der Verwendung die herstellungsgemäßen Bindungskräfte beibehalten. Äußere Einflüsse wie Feuchtigkeit, Staub oder Salz sowie physikalische Einflüsse, u.a. Temperatur und Spannung, verändern die Bindungs- und Werkstoffeigenschaften. Besonders die Bindung zwischen Trägerplatte und Reibmaterial muss diesen Einflüssen widerstehen.The specified in the claim Invention is based on the problem of friction linings that they are not under all operating conditions and over the entire period of Use maintain the binding forces according to the manufacture. External influences like Moisture, dust or salt as well as physical influences, e.g. Temperature and voltage the binding and material properties. Especially the bond between carrier plate and friction material has to withstand these influences.
Mit der Erfindung soll eine Verbesserung der Bindung zwischen Trägerplatte und Reibmaterial erzielt werden.The invention is intended to provide an improvement the bond between the carrier plate and friction material can be achieved.
Die Verbesserung bezieht sich sowohl auf die Festigkeit der Bindung im Hochtemperaturbereich von Reibbelägen (bis ca. 800°C) als auch auf eine weitestgehende Verhinderung von Unterrostung durch die Bildung eines alkalischen Mikromilieus in Gegenwart von Feuchtigkeit.The improvement relates to both the strength of the bond in the high temperature range of friction linings (up to approx. 800 ° C) as well as the greatest possible prevention of under-rusting through the formation of an alkaline micro environment in the presence of moisture.
Durch die Anwendung der Erfindung verringert sich nachhaltig die Gefahr der Ablösung des Reibmaterials von der Trägerplatte nach thermischen und korrosiven Einflüssen. Das Problem wird durch ein Halterungsbett auf der dem Reibbelag zugewandten Seite der Trägerplatte, welches ohne aufwendige Anlage aufgebracht werden kann, gelöst.By applying the invention the risk of detachment of the friction material from is reduced the carrier plate after thermal and corrosive influences. The problem is solved by a Mounting bed on the side of the carrier plate facing the friction lining, which can be applied without complex equipment.
Das Halterungsbett ist formschlüssig mit Reibmaterial unter Beibehaltung der Struktur bepressbar und weist durch seine erfindungsgemäß mineralogisch-chemisch abgestimmte Zusammensetzung thermische Belastbarkeit über den in Reibbelägen vorkommenden Temperaturbereich auf.The mounting bed is form-fitting with friction material compressible while maintaining the structure and points through its mineralogical-chemical according to the invention coordinated composition thermal load capacity over the in friction linings occurring temperature range.
Zur Herstellung des Halterungsbettes wird erfindungsgemäß eine Zubereitung aus einer Natrium- oder Kaliumsilikatlösung, aus einer kolloiden Kiesellösung (Sol) oder aus gelösten organischen Siliciumverbindungen, insbesondere Alkylsilane oder Alkylsiloxane, und Feststoff aus anorganischen, natürlichen oder technischen Silikaten und Silikatverbindungen sowie aus oxidischen und halogenidischen Verbindungen verwendet.For the production of the support bed is a preparation according to the invention from a sodium or potassium silicate solution, from a colloidal silica solution (sol) or from released organic silicon compounds, in particular alkylsilanes or alkylsiloxanes, and solid from inorganic, natural or technical silicates and silicate compounds as well as from oxidic and halide Connections used.
Die Zubereitung für das Halterungsbett weist eine besonders ausgewogene Kohäsion und Adhäsion gegenüber Trägerplatte und Reibmaterial durch die chemische Affinität zwischen der silikatischen Lösung und dem silikatischen Feststoff sowie darauf abgestimmte Vernetzungs- und Kondensationsreaktionen auf.The preparation for the mounting bed has one particularly balanced cohesion and adhesion across from support plate and friction material due to the chemical affinity between the silicate solution and the silicate solid as well as coordinated cross-linking and condensation reactions.
Unter Einstellung der Viskosität der Zubereitung wird mittels den in Patentanspruch 12. beschriebenen Auftragungsverfahren die erforderliche Oberflächenstruktur des Halterungsbettes erzeugt.Adjusting the viscosity of the preparation is by means of the application method described in claim 12 the required surface structure of the support bed generated.

Mit dem beschriebenen Halterungsbett kann ein Reibbelag kostengünstiger gegenüber Halterungsbetten nach den Sinter- oder Aufschweißverfahren hergestellt werden, erzielt eine höhere Temperaturbeständigkeit gegenüber Kleberbindungen auf organischer Basis, und durch die korrosionsschützende Zubereitung der Bindung wird eine Unterrostung, und die damit einhergehende Gefahr der Ablösung des Reibmaterials von der Trägerplatte deutlich verringert.With the bracket bed described a friction lining can be less expensive across from Support beds are manufactured using the sintering or welding process, achieves a higher temperature resistance across from Adhesive bindings on an organic basis and thanks to the anti-corrosion preparation the binding becomes an under rust, and the associated Risk of detachment of the friction material from the carrier plate clearly reduced.
