Description
"Rotor einer Scheibenbremse" Die Erfindung betrifft einen Rotor fur eine Scheibenbremse, bestehend aus einer gußeinsernen Bremsscheibe und einem Träger dafür, wobei der Träger aus einem Bleohtopf mit einem Flansch gebildet ist, der zur Herstellung einer Verzahnung mahrfach unterteilt ist und wobei die Zähne beim Gießen der Bremsscheibe teilweise umgossen werden. "Rotor of a disc brake" The invention relates to a rotor for a disc brake, consisting of a cast-internal brake disc and a carrier therefor, wherein the carrier is formed from a sheet metal pot with a flange, the for the production of a toothing is subdivided several times and with the teeth at Casting the brake disc is partially cast around.
Bei einer bekannten Konstruktion einer Bremsscheibe für Scheibenbremsen, die aus der Reibscheibe und einer topffbrmigen Nabe besteht, ist die Nabe aus Blech hergestellt und als Tiefziehteil ausgebildet, wobei die Blechnabe mit der aus Grauguß bestchend en Reibscheibe durch Eingießen verbunden ist. Die Blechnabe weist dabei an ihrer der Verbind mit der Reibscheibe dienenden Seite einen in radialer Richtung abgebogenen Flansch mit über seinem Umfang verteilten Einschnitten auf, wobei die zwischen den Einschnitten verbliebenen Teile des Flansches in die Reibscheibe eingegossen sind. (DT-OS 2 033 033) Bei diesen bekannten Scheibenbremsen kennen Planlaufabweichungen durch starke Bremslcräfte oder durch infolge starkes Bremsen verursachte Reibungswärme und damit verbundene Wärmespannungen entstehen. Die Folge davon kann das 50genannte Bremsellrubbeln sein.In a known construction of a brake disc for disc brakes, which consists of the friction disc and a cup-shaped hub, the hub is made of sheet metal manufactured and designed as a deep-drawn part, the sheet metal hub with that of gray cast iron bribing friction disc is connected by casting. The sheet metal hub shows on its side serving the connection with the friction disc one in the radial direction bent flange with incisions distributed over its circumference, the Parts of the flange remaining between the incisions are cast into the friction disk are. (DT-OS 2 033 033) Know about these known disc brakes Axial runout deviations due to strong braking forces or as a result of heavy braking The frictional heat caused and the associated thermal stresses arise. The consequence of these, the aforementioned brake rub may be.
Die Aufgabe der Erfindung besteht darin, Verformungen der erwähnten Art sowie auch das Bremsenrubbeln durch Erhöhung der Biegewiderstandsmomente am Ubergang vom Bremsscheibenträger zur Bremsscheibe zu vermeiden. Diese Aufgabe wird dadurch gelöst, daß bei einem Rotor der eingangs bezeichneten Bauart erfinGungsgemäß die Zähne des Flansches des Trägers in zwei übereinanderliegenden Ebenen abgebogen sind. Zur weiteren Erhöhung des Biegewiderstandsmomentes können entsprechend der Anzahl der im Flansch des Trägers angebrachten Blechzähne, in der Wandung des Trägers Wellen eingearbeitet sein. Vorteilhaft erfassen die in zwei Ebenen liegenden Blechzähne die Bremsscheibe an den Außenseiten, ohne daß die Zähne an der Außenseite der Bremsscheibe vorstehen. Bei innenbelüfteter Bremsscheibe können die Zähne an den Stegen angeordnet sein.The object of the invention is to reduce deformations of the aforementioned Art as well as the brake judder by increasing the bending resistance moments on the Avoid transition from the brake disc carrier to the brake disc. This task will solved in that according to the invention in a rotor of the type indicated at the beginning the teeth of the flange of the beam bent in two superimposed planes are. To further increase the moment of bending resistance, according to the Number of sheet metal teeth attached in the flange of the beam, in the wall of the beam Waves to be incorporated. Advantageously grasp the sheet metal teeth lying in two planes the brake disc on the outside without the teeth on the outside of the brake disc protrude. With internally ventilated brake discs, the teeth can be arranged on the webs be.
Die Blechzähne sind vorzugsweise von vier Seiten umgossen, so daß eine starre Verbindung zwischen Bremsscheibe und Träger vorhanden ist. Zur Übertragung des Bremsmomentes weisen die in zwei Ebenen liegenden Blechzähne in Umfangsrichtung ein hohes Widerstandsmoment auf.The metal teeth are preferably cast around from four sides, so that there is a rigid connection between the brake disc and the carrier. To transfer of the braking torque, the sheet metal teeth lying in two planes point in the circumferential direction a high section modulus.
Die Erfindung ist im folgenden anhand schematischer Zeichnungen an Ausführungsbeispielen -riäher erläutert: Von den Figuren zeigen Fig. 1 eine Hälfte eines Schnittes durch einen innenbelüfteten Rotor einer Bremsscheibe nach der Schnittlinie A-A in Fig. 4, Fig. 2 und 5 je einen Schnitt ähnlich Fig. 1 mit einer anderen Verbindung zwischen Bremsscheibe und Träger und Fig. 4 -den Teil einer Ansicht auf einen Rotor nach Fig. 1 in Richtung B.The invention is described below with reference to schematic drawings Exemplary embodiments explained: Fig. 1 shows one half of the figures a section through an internally ventilated rotor of a brake disc along the cutting line A-A in Fig. 4, Fig. 2 and 5 each have a section similar to Fig. 1 with a different connection between the brake disk and the carrier and FIG. 4 - the part of a view of a rotor according to Fig. 1 in the direction B.
Der Rotor besteht aus einer Bremsscheibe 1 oder 10 und einem aus Blech hergestellten Träger 2 mit einem Flansch, der durch in radialer Richtung-abgebogene Zähne 4a, b bzw-. 5a, bigebildet wird-. Die Bremsscheibe 1 (Fig. 1, 2 und 4) ist zwecks Innenbelüf-tung mit Bohrungen-7 oder dgl. versehen.The rotor consists of a brake disc 1 or 10 and one made of sheet metal manufactured carrier 2 with a flange, which is bent by in the radial direction Teeth 4a, b or-. 5a, big is formed-. The brake disc 1 (Fig. 1, 2 and 4) is provided with holes 7 or the like for the purpose of internal ventilation.
Der Träger 2 dient zur Befestigung der Bremsscheibe 1 auf einer nicht dargestellten Nabe. Mit dem Zentrierrand 9 wird der Träger 2 sehr genau auf der Nabe geführt und mit durch die Löcher 8 gehenden Schrauben an einem entsprechenden Teil der Nabe verschraubt0 In der etwa axial -verlaufenden Wandung des Tragers 2 sind Wellen 6 eingedrückt.-Die Zähne am äußeren Teil des Trägers 2 sind in zwei Ebenen abgeLooen. An-den außen -iiegenden Teilen der Wellen 6 sind die Zähne 4a, b und an den innenliegenden Teilen der Wellen die Zähne 5a, b vorgesenen, so daß bei den innenbelüfteten Bremsscheiben eine Verstärkung der Belüftung erzielt wird. Hierbei -werden die Zähne derart auf den Umfang der Bremsscheibe 2 verteilt, daß sie mit den zwischen den Bohrungen 7 liegenden Stegen 3 übereinstimmen.The carrier 2 is used to fasten the brake disc 1 on a non shown hub. With the centering edge 9, the carrier 2 is very accurate on the Hub guided and with screws going through the holes 8 on a corresponding one Part of the hub screwed 0 In the approximately axially extending wall of the support 2 shafts 6 are pressed in. -The teeth on the outer part of the carrier 2 are in two Loosing levels. On-the-outside-lying Parts of the shafts 6 are the teeth 4a, b and on the inner parts of the shafts the teeth 5a, b pre-cut, so that an increase in ventilation is achieved in the case of internally ventilated brake discs will. Here, the teeth are distributed over the circumference of the brake disc 2 in such a way that that they coincide with the webs 3 lying between the bores 7.
Durch die Verbindung des- Trägers 2 mit der Bremsscheibe 1 mittels der Zähne 4a, b und 5a, b in zwei übereinanderliegenden Ebenen wird das Widerstandsmoment bedeutend erhöht, so daß Planlaufabweichungen und Bremsenrubbeln besser verhindert werden können. Das Widerstandsmoment wird am größten, wenn die Zähne 4a, 5a in Fig. 5 bzw. 4b, 5b in Fig. 2 die Bremsscheibe 10 bzw. 1 an den Außenseiten erfassen. Hierbei können die Zähne 4a, b und 5a, b in die Bremsscheibe derart eingesetzt sein, daß sie an den Außenseiten der Bremsscheibe nicht vorstehen.By connecting the carrier 2 to the brake disc 1 by means of of the teeth 4a, b and 5a, b in two superimposed levels is the section modulus significantly increased, so that axial run-out deviations and brake juddering are better prevented can be. The section modulus is greatest when the teeth 4a, 5a in Fig. 5 and 4b, 5b in Fig. 2 detect the brake disc 10 or 1 on the outer sides. The teeth 4a, b and 5a, b can be inserted into the brake disc in such a way that that they do not protrude on the outside of the brake disc.
