Description

Verfahren zur Herstellung einer Bremsscheibe und BremsscheibeMethod for producing a brake disk and brake disk
Die Erfindung betrifft ein Verfahren zur Herstellung einer Bremsscheibe nach dem Oberbegriff des Anspruchs 1, sowie eine Bremsscheibe nach dem Oberbegriff des Anspruchs 5.The invention relates to a method for producing a brake disk according to the preamble of claim 1, as well as a brake disk according to the preamble of claim 5.
Moderne Hochleistungsbremsscheiben sind im Einsatz bei Pkw und Lkw sehr hohen mechanischen, tribologischen und thermischen Belastungen ausgesetzt. Zudem wird aufgrund der ungefederten Masse stets eine Minimierung des Bremsscheibengewichtes angestrebt .Modern high-performance brake discs are exposed to very high mechanical, tribological and thermal loads when used on cars and trucks. In addition, a minimization of the brake disc weight is always sought due to the unsprung mass.
Hierzu wird ein Bremsscheibentopf und ein Reibring häufig aus unterschiedlichen Materialien getrennt dargestellt und anschließend zur Bremsscheibe zusammengefügt.For this purpose, a brake disk pot and a friction ring is often shown separately from different materials and then assembled to the brake disc.
Die Fügetechnik zwischen Topf und Reibring ist in der Regel aufwendig, da zwischen Bremsscheibentopf und Reibring hohe Momente und Scherkräfte übertragen werden. In der EP 1 476 670 Bl ist vorgesehen, einen Bremsscheibentopf durch ein Innenhochdruckverfahren an einen Reibring zu formen, wobei der Reibring nach innen gerichtete Pyramidenstümpfe aufweist, um die der Bremsscheibentopf herumgeformt wird.The joining technique between pot and friction ring is usually expensive, since between brake disc and friction ring high moments and shear forces are transmitted. In EP 1 476 670 Bl, it is provided to form a brake disk pot by means of an internal high-pressure method onto a friction ring, wherein the friction ring has inwardly directed truncated pyramids around which the brake disk cup is formed.
Der Erfindung liegt die Aufgabe zu Grunde einen Verbindung zwischen einen Bremsscheibentopf und einem Reibring zu gestalten, die eine gegenüber dem Stand der Technik, höher mechanische Belastbarkeit aufweist und dabei kostengünstig herstellbar ist. Die Lösung der Aufgabe besteht in einem Verfahren zur Herstellung einer Bremsscheibe mit den Merkmalen des Anspruchs 1 sowie in einer Bremsscheibe mit den Merkmalen des Anspruchs 5.The invention is based on the object to make a connection between a brake disk hub and a friction ring, which has a relation to the prior art, higher mechanical strength and is inexpensive to produce. The solution of the problem consists in a method for producing a brake disc having the features of claim 1 and in a brake disc having the features of claim 5.
Das Verfahren zur Herstellung einer Bremsscheibe nach Anspruch 1 besteht darin, dass ein Bremsscheibentopf und ein Reibring durch einen Umformprozess zusammengefügt werden. Dabei wird durch den Umformprozess von Seite des Bremsscheibentopfes Material radial nach außen gepresst und in ebenfalls radial nach außen verlaufende Vertiefungen im Reibring eingeformt.The method for producing a brake disk according to claim 1 is that a brake disk pot and a friction ring are joined together by a forming process. In this case, material is pressed radially outward by the forming process from the side of the brake disk pot and formed in also radially outwardly extending recesses in the friction ring.
Das eingeformte Material kann Material vom Bremsscheibentopf selbst sein oder durch zusätzliche Verbindungselemente wie etwa Nieten eingebracht werden, die durch Öffnungen im Bremsscheibentopf geformt werden.The molded material may be material from the brake disk pot itself or may be introduced by additional fasteners such as rivets formed through openings in the brake disk pot.
Durch dieses Verfahren kann prozesstechnisch kostengünstig, da ein Umformprozess bei Raumtemperatur möglich ist, und mechanisch zuverlässig eine Verbindung zwischen Bremsscheibentopf und Reibring dargestellt werden.By this method can process technology cost, since a forming process at room temperature is possible, and mechanically reliable a connection between the brake disk chamber and friction ring are shown.
Ein weiterer Bestandteil der Erfindung ist eine Bremsscheibe mit den Merkmalen des Anspruch 5.Another component of the invention is a brake disc having the features of claim 5.
Vorteilhafte Ausgestaltungsformen ergeben sich aus den Unteransprüchen .Advantageous embodiments emerge from the subclaims.
An Hand der folgenden Spezialbeschreibung werden bestimmte Merkmale der Erfindung am Beispiel ausgewählter Figuren näher erläutert. Merkmale mit derselben Bezeichnung und unterschiedlicher Ausgestaltung werden dabei mit dem selben Bezugszeichen versehen. Dabei zeigen:With reference to the following special description certain features of the invention using the example of selected figures are explained in detail. Features with the same name and different design are provided with the same reference numerals. Showing:
Fig. 1 einen Bremsscheibentopf,1 a brake disk pot,
Fig. 2 eine zusammengesetzte Bremsscheibe,2 is a composite brake disc,
Fig. 3 einen Reibring,3 shows a friction ring,
Fig. 4 eine weitere zusammengesetzte Bremsscheibe undFig. 4 shows another composite brake disc and
Fig. 5 einen Ausschnitt der Bremsscheibe aus Fig. 4.5 shows a detail of the brake disk from FIG. 4.
In Fig. 1 ist ein Bremsscheibentopf 4 dargestellt, der beispielsweise aus einer Aluminiumlegierung geformt ist und in einem Druckgussverfahren hergestellt ist. Im Gegensatz dazu besteht ein Reibring 6 in Fig. 3 aus einer Gusseisenlegierung und ist durch ein Eisengießverfahren dargestellt .In Fig. 1, a brake disk chamber 4 is shown, which is formed for example of an aluminum alloy and is produced in a die-casting process. In contrast, a friction ring 6 in Fig. 3 is made of a cast iron alloy and is represented by an iron casting method.
In Figur 2 ist ein Querschnitt durch eine Bremsscheibe dargestellt, wobei der Bremsscheibentopf 4 mit dem Reibring zusammengefügt ist. Das Fügen erfolgt durch einen Innenhochdruckumformprozess, wobei der Reibring 6 und der Bremsscheibentopf 4 so in ein Werkzeug eingelegt werden, dass die gegenseitige Position im Wesentlichen der Bremsscheibe entspricht. Durch besonders hohen Druck, der beispielsweise hydrostatisch aufgebracht wird, werden Zapfen 22 die bereits im Bremsscheibentopf vorhanden sind, radial nach außen gepresst, so dass sie in Vertiefungen 8, in Form von Sacklöcher 18 im Reibring 6 hineingeformt werden. Die ursprünglich kurzen Zapfen 22 werden somit durch den hohen Druck längs verformt, was in der Regel mit einer Verjüngung der Wandstärke einhergeht.FIG. 2 shows a cross section through a brake disk, the brake disk chamber 4 being joined to the friction ring. The joining takes place by means of a hydroforming process, wherein the friction ring 6 and the brake disk chamber 4 are inserted into a tool such that the mutual position substantially corresponds to the brake disk. By particularly high pressure, which is applied for example hydrostatically, pins 22 which are already present in the brake disk chamber are pressed radially outward, so that they are formed into recesses 8 in the form of blind holes 18 in the friction ring 6. The originally short pins 22 are thus deformed longitudinally by the high pressure, which is usually accompanied by a rejuvenation of the wall thickness.
Die Zapfen 22 sitzen nach dem Umformen formschlüssig in den Vertiefungen 8 und sichern den Bremsscheibentopf 4 gegenüber dem Reibring 6 in axialer Richtung 24 und in tangentialer Richtung 28.The pins 22 sit after forming positively in the recesses 8 and secure the brake disc hub 4 opposite the friction ring 6 in the axial direction 24 and in the tangential direction 28th
Die Vertiefungen 8 können auch in Form von axial angelegten Nuten 20 ausgestaltet sein, wie es in Fig. 4 dargestellt ist. In diesem Fall ist eine zusätzliche axiale Sicherung beispielsweise in Form eines Sicherungsringes zweckmäßig.The recesses 8 may also be configured in the form of axially-shaped grooves 20, as shown in Fig. 4. In this case, an additional axial securing, for example in the form of a retaining ring is appropriate.
In Fig. 5 ist eine weitere Ausgestaltungsform einer Bremsscheibe 2 dargestellt. Diese Bremsscheibe 2 ist mit einer Innenbelüftung ausgestaltet, was sich durch zwei, durch Stege 28 getrennte Reibscheiben 30 äußert, die zusammen den Reibring 6 bilden. Analog zu den Figuren 1 - 3 ist auch hier ein Bremsscheibentopf 4 mit dem Reibring 6 durch einen Umformprozess verbunden.5, a further embodiment of a brake disc 2 is shown. This brake disc 2 is designed with an internal ventilation, which manifests itself by two friction plates 30 separated by webs 28, which together form the friction ring 6. Analogously to FIGS. 1-3, a brake disk pot 4 is also connected to the friction ring 6 by a forming process.
Die Bremsscheibe 4 aus Figur 5 unterscheidet sich von dem vorangegangenen Beispiel darin, dass nicht das Material des Bremsscheibentopfes 4, nämlich die Zapfen 22 in Vertiefungen 8 gepresst werden. In diesem Beispiel wird ein zusätzliches Material in Form von Verbindungselementen 10 eingesetzt, die in diesem Ausführungsbeispiel wiederum in Form von Nieten 32 ausgestaltet sind. Die Nieten 32 werden durch Öffnungen 12 im Bremsscheibentopf 4 in die in radialer Richtung 26 verlaufenden Vertiefungen 10 des Reibrings gepresst. Auch in diesem Beispiel wird .für das Einpressen der Nieten ein Innenhochdruckumformprozess angewandt. Grundsätzlich kann für beide Ausführungsbeispiele auch ein Ziehstempel angewendet werden, der die Zapfen 22 bzw. die Nieten 32 in die dafür vorgesehenen Vertiefungen 8 presst.The brake disk 4 from FIG. 5 differs from the preceding example in that it is not the material of the brake disk cup 4, namely the pins 22, that are pressed into recesses 8. In this example, an additional material in the form of connecting elements 10 is used, which in turn are configured in the form of rivets 32 in this embodiment. The rivets 32 are pressed through openings 12 in the brake disk chamber 4 in the radial direction 26 extending recesses 10 of the friction ring. Also in this example, a hydroforming process is used to press in the rivets. In principle, a drawing punch can also be used for both embodiments, which presses the pins 22 or the rivets 32 into the depressions 8 provided for this purpose.
Die Vertiefungen 10 im Reibring 6 nach Fig. 5 weisen Hinterschneidungen 34 auf, die in der vergrößerten Schnittdarstellung nach Fig. 6 erkennbar sind. Durch den Umformdruck werden die Nieten (die als Vollnieten oder Hohlnieten ausgestaltet sein können) in der Vertiefung 10 aufgeweitet und in die Hinterschneidungen 34 gepresst, was die Festigkeit der Verbindung noch weiter erhöht.The depressions 10 in the friction ring 6 according to FIG. 5 have undercuts 34, which can be seen in the enlarged sectional view of FIG. By the forming pressure, the rivets (which can be configured as solid rivets or rivets) in the recess 10th expanded and pressed into the undercuts 34, which further increases the strength of the connection.
Die Vertiefungen 10 sind in axialer Richtung 24 bevorzugt mittig angeordnet, wodurch eine Schirmung der Bremsscheibe minimiert wird. Unter Schirmung versteht man eine schirmförmige Wölbung des Reibrings 4, die durch eine unterschiedliche Wärmeausdehnung des Bremsscheibentopfes und des Reibrings 6 hervorgerufen wird. Unter mittiger Anordnung soll hierbei ein Versatz von 10 % von der axialen Mitte in beide axiale Richtungen verstanden werden.The recesses 10 are preferably arranged centrally in the axial direction 24, whereby a shielding of the brake disc is minimized. Shielding means an umbrella-shaped curvature of the friction ring 4, which is caused by a different thermal expansion of the brake disk hub and the friction ring 6. A central arrangement should be understood to mean an offset of 10% from the axial center in both axial directions.
Weiterhin ist es zweckmäßig, zur Wärmeisolation zwischen Reibring 6 und Bremsscheibentopf 4 eine Isolationsschicht, beispielsweise in Form einer Eisenfolie einzufügen. Zudem kann in den Vertiefungen und/oder an den Kontaktflächen Zinkstaub eingefügt werden, der zur Vermeidung von Kontaktkorrosion führt.Furthermore, it is expedient to insert an insulation layer, for example in the form of an iron foil, for thermal insulation between friction ring 6 and brake disk chamber 4. In addition, zinc dust can be introduced into the recesses and / or at the contact surfaces, which leads to the avoidance of contact corrosion.
Es ist noch darauf hinzuweisen, dass bei der Umformung der Nieten oder des Materials des Bremsscheibentopfs in die Vertiefungen des Reibrings dessen Oberflächenrauhigkeit, die auf den Gießprozess zurückzuführen ist, vorteilhaft ist. Es entsteht so ein Mikroformschluss zwischen Topfmaterial bzw. Nietmaterial und Reibringoberfläche. Dieser Mikroformschluss unterbindet Relativbewegungen, die ansonsten bei feinbearbeiteten formschlüssigen Welle-Nabenverbindungen auf Grund von wechselnder Momentenbelastung und Temperaturschwankungen auftreten. Es tritt somit bei den beschriebenen Verbindung kein so genannter „Mikroschlupf" auf, der häufig zum Versagen von Welle-Naben-Verbindungen führt. Bezugs zeichenlisteIt should also be noted that in the forming of the rivets or the material of the brake disk hub into the recesses of the friction ring whose surface roughness, which is due to the casting process, is advantageous. This creates a microforming connection between pot material or rivet material and friction ring surface. This microforming prevents relative movements that otherwise occur in finely machined positive shaft-hub connections due to changing moment load and temperature fluctuations. Thus, there is no so-called "micro-slip" in the connection described, which often leads to the failure of shaft-hub connections. Reference sign list
