Description

Aufkohlen eines Brems- und Kupplungsbelages aus Eisen oder Stahl Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Brems- oder Kupplungsbelages aus Eisen oder Stahl, bei dem ein Aufkohlungsvorgang durchgeführt wird. Sie besteht darin, daß die Kupplungs-oder Bremskräfte übertragenden Flächen (Außenschicht des Körpers bzw. Beläge) durch eine geeignete Einsatzbehandlung so stark mit Kohlenstoff überreichert werden, daß eine Ausbildung von Zementit in Netzform vorhanden ist. Der Vorteil dieses. Verfahrens liegt darin, daß einer Zerstörung der miteinander zusammenwirkenden Körper in erheblichem Maße entgegengetreten wird.Carburizing a brake and clutch lining made of iron or steel Die The invention relates to a method for producing a brake or clutch lining made of iron or steel, on which a carburizing process is carried out. she consists in that the surfaces transmitting the clutch or braking forces (outer layer of the Body or coverings) so strongly with carbon through a suitable insert treatment be enriched that there is a formation of cementite in the form of a network. The advantage of this. Procedure is that a destruction of each other cooperating body is countered to a considerable extent.

Es ist an sich bekannt, für Brems- und Kupplungskörper oder Beläge Metall zu ver-.w .enden, insbesondere Eisen und Stahl. Es ist weiter bekannt, -daß mit Rücksicht auf die Abnutzung die beiden in. Verbindung stehenden Teile, z. B. Kupplungskörper und Kupphingsbacken, einen verschiedenen Gefügeaufbau besitzen. Ferner hat man auch die Oberfläche der Bremstrommel im Einsatz aufgekohlt und gehärtet, während man für die Bremsbacken einen Werkstoff verwendet hat, dessen Oberfläche durch geeignete Verfahren aufgekohlt und gehärtet, jedoch angelassen wird, um eine niedrigere Oberflächenfestigkeit für die Bremstrommel zu erreichen.It is known per se to use metal, in particular iron and steel, for brake and clutch bodies or linings. It is also known that, with a view to wear and tear, the two related parts, e.g. B. Coupling body and Kupphingsbacken, have a different structure. Furthermore, the surface of the brake drum has also been carburized and hardened in use, while a material has been used for the brake shoes, the surface of which is carburized and hardened by suitable processes, but tempered in order to achieve a lower surface strength for the brake drum.

Das erfindungsgemäße Verfahren wird zweckmäßig in der Weiss durchgeführt, daß beispielsweise im Falle eines Bremskörpers die Oberfläche der Bremsbacken in der genannten Weise behandelt wird. Die Bremstrommel selbst kann dann auch aus einem anderen wie oben angegebenen Werkstoff bestehen. Das erfindungsgemäße Verfahren kann auch für Kupplungslamnellen und'/oder Einzelteile für Kupplungen angewendet werden.The method according to the invention is expediently carried out in the white, that, for example, in the case of a brake body, the surface of the brake shoes in treated in the manner mentioned. The brake drum itself can then also consist of a other material as specified above. The inventive method can also be used for clutch plates and / or individual parts for clutches will.

PATENTANSPRUCH: Verfahren zur Herstellung eines Brems-und Kupplungsbelages aus Eisen oder Stahl, bei dem ein Aufkohlungsvorgang durchgeführt wird, dadurch gekennzeichnet, daß der Aufkohlungsvorgang als Überkohlungsvorgang in der Weise durchgeführt wird, daß die die Kupplungs-oder Bremskräfte übertragenden Flächen (Außenschicht des Körpers bzw. Beläge) durch eine geeignete Einsatzbehandlung so stark mit Kohlenstoff überreichert werden, daß ,eine Ausbildung von Zementit in \ etzform vorhanden ist. Zur Abgrenzung des Anmeldungsgegenstandes vom Stand der Technik sind im Erteilungsverfahren in Betracht gezogen worden: deutsche Patentschrift Nr. 650 739, Brearley-Schäfer, >.Die Einsatzhärtung von Stahl und Eisen«, 1926, S.51 bis 57, Abb.32 und 33.PATENT CLAIM: A method for producing a brake and clutch lining made of iron or steel, in which a carburizing process is carried out, characterized in that the carburizing process is carried out as an overcarburizing process in such a way that the surfaces (outer layer of the body or . Deposits) are so heavily enriched with carbon through a suitable treatment that cementite is formed in the form of a network. To distinguish the subject matter of the application from the state of the art, the following were considered in the granting procedure: German patent specification No. 650 739, Brearley-Schäfer,>.
