Bei dem Verfahren zur Herstellung einer Verbundbremsscheibe, die einen Bremsscheibentopf und einen Bremsring (3) mit einer Innenprofilierung (2) aufweist, wird ein Bremsscheibentopfrohling (1a) in den Bremsring (3) eingebracht. Dann wird mittels mindestens eines Prägewerkzeugs (7) der Bremsscheibentopfrohling (1a) in die Innenprofilierung (2) eingeformt. Auf diese Weise kann kaltumformend eine Verbundbremsscheibe erstellt werden, die eine gute Drehmomentübertragung zwischen Bremsring (3) und Bremsscheibentopf ermöglicht. Das Einformen kann in hämmernder Art stattfinden, insbesondere durch ein Hintereinanderausführen einer Mehrzahl von Prägeschritten im Bereich verschiedener Profillücken der Innenprofilierung (2). Bei dem Einformen können gleichzeitig auch Axialbegrenzungen erzeugt werden, durch die ein axiales Auseinanderschieben von Bremsscheibentopf und Bremsring (3) verhindert wird.

Composite brake disc and method and apparatus for manufacture of the same

With the method for manufacturing a composite brake disc, which includes a brake disc chamber and a friction ring having an inner profiling, a brake disc chamber blank is introduced into the friction ring. The brake disc chamber blank is then formed into the inner profiling via at least one embossing tool. A composite brake disc permitting a good torque transmission between the friction ring and the brake disc chamber can be manufactured in a cold-forming manner in this way. The forming-in can take place in a hammering manner, in particular by successively implementing a plurality of embossing steps in the region of different profile gaps of the inner profiling. Axial stops can also be simultaneously produced on forming-in. The axial stops serve to stop the brake disc chamber and the friction ring (3) are prevented from axially sliding apart.
