Description

Reibkörper aus Leichtmetall für Reibungsbremsen oder Reibungskupplungen Es sind Reibkörper für Reibungsbremsen oder Reibungskupplungen in Form einer umlaufenden Scheibe bekannt, bei denen nur die Reibfläche aus Stahl besteht, während der übrige Teil der Scheibe aus Leichtmetall gebildet ist. Ein derartiger Reibkörper weist ein wesentlich geringeres Schwungmoment auf als ein aus Stahl bestehender Reibkörper. Nachteilig ist bei Anwendung von Leichtmetall für den Reibkörper jedoch die geringe Festigkeit dieses Materials, so daß es Schwierigkeiten bereitet, einen solchen Reibkörper dauerhaft mit der Welle zu verbinden.Friction body made of light metal for friction brakes or friction clutches There are friction bodies for friction brakes or friction clutches in the form of a circumferential Disc known in which only the friction surface is made of steel, while the rest Part of the disc is made of light metal. Such a friction body has a significantly lower moment of inertia than a friction body made of steel. However, when using light metal for the friction body, the disadvantage is the small amount Strength of this material, so that it is difficult to create such a friction body to be permanently connected to the shaft.

Die Erfindung vermeidet diese Schwierigkeiten und schlägt vor, die Nabe des Reibkörpers aus einem Baustoff herzustellen, dessen Festigkeit größer ist als die des Leichtmetalls, z. B. aus Gußeisen. Am einfachsten geht man dabei so vor, daß man die auf ihrem Umfang mit Rillen, Vorsprüngen od. dgl. versehene Nabe vor dem Gießen des Reibkörpers in die Form einbringt, womit eine innige Verbindung zwischen Nabe und Leichtmetallkörper ohne Anwendung besonderer Befestigungsmittel erzielt wird.The invention avoids these difficulties and proposes that Manufacture the hub of the friction body from a building material whose strength is greater than that of the light metal, e.g. B. made of cast iron. The easiest way to do this is to do this before that one on its circumference with grooves, projections or the like. Provided hub brings the friction body into the mold before casting, creating an intimate connection between the hub and the light metal body without the use of special fasteners is achieved.
