Abstract

Brake linings used in automotive disks are usually composed of various components. The expected properties of a brake lining are the standard values of wear resistance, friction coefficient and the economical manufacturing. Brake lining extremely warms up during braking due to friction. The braking performance of braking lining can change or the braking lining undergoes mechanical deformation due to excessive temperature. In this study, the effect of granite powder in the brake friction material on various aspects of friction characteristics were investigated. Three friction material specimens were produced based on an experimental formulation, and they contained 2, 6 and 10 % granite powder, respectively, with fixed composition of the other ingredients. Tribological properties of the friction materials were obtained using a brake dynamometer. Results showed that the friction materials containing 2 and 6 % granite powder had improved friction stability and fade resistance.

Kurzfassung

Bremsbeläge, wie sie in der Automobilindustrie verwendet werden, sind üblicherweise aus verschiedenen Komponenten zusammengesetzt. Bremsbeläge sollen die Standardwerte des Verschleißwiderstandes und des Reibkoeffizients erfüllen sowie eine möglichst ökonomische Fertigung erlauben. Bremsbeläge erwärmen sich extrem während des Bremsvorganges infolge von Reibung. Die Bremswirkung von Bremsbelägen ist veränderlich, wenn der Bremsbelag mechanischer Verformung infolge der exzessiven Temperaturen ausgesetzt war. In der diesem Beitrag zugrunde liegenden Studie wurde die Wirkung von Granitpulver in dem Bremsbelagmaterial unter den verschiedenen Reibcharakteristika untersucht. Es wurden drei Proben mit verschiedenen Reibmaterialien, basierend auf einer experimentellen Entwicklung mit entsprechend 2, 6 und 10 % Granitpulver untersucht, wobei die Zusammensetzung der anderen Komponenten entsprechend beibehalten wurde. Es wurden die tribologischen Eigenschaften der Reibmaterialien mit einem Bremsdynamometer ermittelt. Die Ergebnisse zeigen, dass die Reibmaterialien mit einem Zusatz von 2 bzw. 6 % Granitpulver die Reibstabilität und den Bremsschwund verbesserten.
