Description
Die Erfindung bezieht sich auf Zweistoffbremstrommeln, wie solche im Kraftfahrzeugbau bereits bekanntgeworden sind. Zweistoffbremstrommeln sind solche, bei denen eine Trommel, beispielsweise aus Stahl, mit einer Schicht ausgekleidet wird, die zusammen mit dem Bremsbelag der Bremsbacken eine gute Bremswirkung ergibt. Es ist beispielsweise bekannt, eine Graugußschicht in eine Stahlblechtrommel einzugießen oder einzuschleudern; es ist ferner bekanntgeworden, einen Bremsring mit geeignetem Material zu umgießen oder einen Bremsring in eine Trommel einzuschrumpfen.The invention relates to dual fuel brake drums such as those have already become known in automotive engineering. Dual-fuel brake drums are those in which a drum, for example made of steel, lined with a layer which, together with the brake lining of the brake shoes, gives a good braking effect. It is known, for example, to cast a layer of gray cast iron into a sheet steel drum or to throw in; It has also become known to have a brake ring with a suitable Pouring around material or shrinking a brake ring into a drum.
Bei allen diesen Zweistofftrommeln kommt es besonders darauf an, neben ausreichender mechanischer Festigkeit eine gute Wärmeabführung zu erreichen. Der Wärmeübergang wird beispielsweise bei aufgeschrumpften Bremstrommeln durch die Trennfläche zwischen den beiden Werkstoffen nachteilig beeinflußt, die Wärme muß also vom Bremsring erst auf die Bremstrommel übergehen und kann von dort aus' in die umgebende Luft abgeführt werden. Hierzu ist schon bekanntgeworden. die äußere Bremstrommel mit einer Verrippung zu versehen, um die Wärmeübergangsfläche zu vergrößern.With all of these two-material drums, it is particularly important next to sufficient mechanical strength to achieve good heat dissipation. Of the Heat is transferred through the parting surface, for example in the case of shrunk-on brake drums adversely affected between the two materials, so the heat must come from the brake ring only pass to the brake drum and can from there 'into the surrounding air be discharged. This has already become known. the outer brake drum with to provide ribs to increase the heat transfer surface.
Zu diesem Zweck wird erfindungsgemäß ein Bremsring so ausgebildet, daß an der Außenseite angeordnete Rippen, Lappen oder irgendwelche Vorsprünge durch die Bremstrommel hindurchreichen, so daß also die Wärmeabgabe unmittelbar vom Bremsring an die Außenluft erfolgt.For this purpose, a brake ring is designed according to the invention in such a way that that on the outside arranged ribs, lobes or any projections through the brake drum reach through, so that the heat dissipation directly from the brake ring to the outside air.
Die Herstellung von Bremstrommeln gemäß der Erfindung erfolgt zweckmäßig durch Umgießen des Bremsringes. Der Bremsring, der vorzugsweise aus Grauguß besteht, kann mit Rippen aus besonders gut wärmeleitfähigem Material, wie z. B. Kupfer, versehen sein. Es ist dabei unerheblich, ob die Rippen aus einem andersartigen Material wie der Bremsring durch Aufgießen, Aufschleudern, Ausschleudern aus einer Grauguß-Kupfer-Legierung oder auf andere Weise hergestellt werden.The manufacture of brake drums according to the invention is expedient by casting around the brake ring. The brake ring, which is preferably made of gray cast iron, can with ribs made of particularly good thermally conductive material, such as. B. copper, provided be. It is irrelevant whether the ribs are made of a different material such as the brake ring by pouring on, spinning on, spinning out of a gray cast iron-copper alloy or otherwise produced.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Abbildung dargestellt.An embodiment of the subject matter of the invention is shown in the figure shown.
Ein Bremsring I ist an der Außenseite mit ringförmigen Rippen 2 oder einzelnen Lappen oder Erhöhungen 3 versehen. Diese Rippen oder Lappen ragen durch den zylindrischen Teil 4 der Bremstrommel 5 hindurch.A brake ring I is on the outside with annular ribs 2 or individual tabs or elevations 3 provided. These ribs or lobes protrude through the cylindrical part 4 of the brake drum 5 therethrough.
