Die bisher bekannten Bremsklötze aus Eisen, Asphalt und Steinmaterial wurden während der beim Bremsen auftretenden Erhitzung und durch Schmiermaterial leicht weich, bröckelten aus und waren infolge dessen ebenso wie die Radreifen einem schnellen Verschleifs unterworfen. The previously known brake pads made of iron, asphalt and stone material were used during the heating that occurs during braking and slightly soft due to the lubricating material, crumbled and as a result, like the wheel tires, were subject to rapid wear and tear.
,Durch Anwendung einer zur Herstellung von Baumaterial bereits bekannten Mischung von Eisen, Asphalt und Schwefel werden diese Uebelstände vermieden, indem durch Einführung einer verhältnifsmäfsig geringen Menge Schwefel in die Asphaltmasse eine bessere Verbindung der einzelnen Theile der Masse unter sich und mit dem aus Eisen bestehenden Auflager bewirkt wird. Hierbei wirkt der Schwefel infolge der Erhitzung, der die Materialien vor dem Einbringen unterworfen werden, sowohl auf das Eisen als auch auf den Asphalt und verbindet sich mit letzterem, den Zusammenhang der Masse befördernd. Der Schwefel erhöht dabei die Härte des Asphalts erheblich, ohne denselben brüchig zu machen.By using a mixture of Iron, asphalt, and sulfur are avoided by introducing them a relatively small amount of sulfur in the asphalt mass a better connection of the individual parts of the mass among themselves and with the support made of iron is effected. Here, the sulfur acts as a result of the heating, which the materials in front of be subjected to the incorporation, both on the iron and on the asphalt and connects with the latter, promoting the cohesion of the mass. The sulfur increases the hardness of the asphalt considerably without making it brittle.
Eine Mischung von 16 Theilen Eisen oder Stahl in fein vertheiltem Zustande, 8 Theilen Asphalt und 1 Theil Schwefel hat sich für diesen Zweck als vorzugsweise geeignet erwiesen. Der Schwefel wird mit dem geschmolzenen Asphalt bei hoher Temperatur, beispielsweise 200 bis 2100C, gemischt, das Eisen als Eisen- oder Stahlspäne zugegeben und die Masse, nachdem sie vollkommen gleichmäfsig geworden ist, in heifsem Zustande in die Form eingeprefst.A mixture of 16 parts iron or steel in a finely divided state, 8 parts asphalt, and 1 part sulfur has been found to be particularly suitable for this purpose. The sulfur is with the molten asphalt at high temperature, for example 200 ° to 210 0 C, mixed, the iron is added as ferrous or steel chips and after it has become completely gleichmäfsig, eingeprefst the mass in hot condition into the mold.
