Description
zweiten Radbremszylinder liegenden Teile des Bremsbelages einen höheren Reibungskoeffizienten als die übrigen Bremsbelagteile aufweisen.Second wheel brake cylinder lying parts of the brake lining have a higher coefficient of friction have than the other brake lining parts.
Die erfindungsgemäße Lösung ermöglicht es, auf einfache Weise bei beiden Kr äsen der Doppelkreis-Scheibenbremse die gewünschte Bremswirkung zu sichern, ohne daß es notwendig wäre, Bestandteile mit ungleichen Durchmessern und Formen oder zwei Hauptzylinder zu verwenden, und de ermöglicht auch, weitere technologische Operationen einzuführea. Sie vereinfacht den Herstellungsprozeß und steigert die Möglichkeit einer serienmäßigen Herstellung. The solution according to the invention makes it possible, in a simple manner, for both cutters of the double-circle disc brake to ensure the desired braking effect without it being necessary to use components Unequal diameters and shapes or two main cylinders can be used, and de enables also to introduce further technological operations a. It simplifies the manufacturing process and increases the possibility of serial production.
