Abstract
Description
Die Erfindung betrifft eine Bremsscheibe für eine Scheibenbremse eines Kraftwagens, mit einem Bremsscheibentopf und einem koaxial zu diesem angeordneten Reibring.The The invention relates to a brake disc for a disc brake Motor vehicle, with a brake disc pot and a coaxial to this arranged friction ring.
Derartige Bremsscheiben sind dem Stand der Technik als allgemein bekannt zu entnehmen. Im Zuge gegenwärtiger Leichtbaubestrebungen geht die Tendenz dahin, Bremsscheibentopf und Reibring als separate Bauteile auszuführen, da an die jeweiligen Bauteile unterschiedliche Ansprüche bezüglich ihrer Materialbeschaffenheit gestellt werden. Der Reibring besteht dabei vorzugsweise aus Gusseisen, da dieses besonders gute tribologische und Wärmeleiteigenschaften aufweist. Aus Gründen der Gewichtseinsparung wird der Bremsscheibentopf dagegen bevorzugt aus Stahl- oder Leichtmetallblech gefertigt und in der Folge mit dem Reibring verbunden. Die Verbindung, die beispielsweise durch Innenhochdruckumformen des Bremsscheibentopfes erzeugt wird, ist dabei in der Regel irreversibel, so dass bei Beschädigungen eines der beiden Bauteile die komplette Bremsscheibe ausgetauscht werden muss. Gegenwärtig verwendete Verbindungsmethoden erlauben zudem kein axiales oder radiales Spiel zwischen Bremsscheibentopf und Reibring, so dass es aufgrund der unterschiedlichen Ausdehnungskoeffizienten von Gusseisen und Stahl bzw. Aluminium/Magnesium-Legierungen zu thermischen Spannungen im Betrieb der Bremsscheibe kommen kann. Dies führt im ungünstigsten Fall zu Schirmung der Bremsscheibe, was den Belagschrägverschleiß der Scheibenbremse erhöht und unerwünschten, den Komfort der Fahrzeuginsassen beeinträchtigenden Körperschall erzeugt.such Brake discs are known in the art as well remove. In the course of current Lightweight construction efforts, there is a tendency, brake disc pot and perform friction ring as separate components, as to the respective components different claims in terms of their material properties are made. The friction ring exists preferably made of cast iron, since this is particularly good tribological and thermal conduction properties having. For reasons In contrast to the weight saving, the brake disk cup is preferred made of steel or light metal sheet and in the episode with connected to the friction ring. The connection, for example, by Hydroforming of the brake disc hub is generated is as a rule irreversible, so that in case of damage one of the two components replaced the entire brake disc must become. Currently used connection methods also do not allow axial or Radial clearance between brake disc and friction ring, so that it due to the different expansion coefficients of cast iron and steel or aluminum / magnesium alloys to thermal stresses can come in operation of the brake disc. This leads in the worst case to shielding the brake disc, which increases the lining oblique wear of the disc brake and unwanted, the comfort of the vehicle occupants impairing structure-borne noise generated.
Der Erfindung liegt somit die Aufgabe zugrunde, eine Bremsscheibe der eingangs genannten Art so weiterzuentwickeln, dass der Austausch von beschädigten Einzelteilen ermöglicht wird und das thermische Verhalten der Bremsscheibe verbessert wird.Of the Invention is therefore the object of a brake disc of to develop at the outset so that the exchange from damaged Items allowed is and the thermal behavior of the brake disc is improved.
Diese Aufgabe wird durch eine Bremsscheibe mit den Merkmalen des Patentanspruchs 1 gelöst.These The object is achieved by a brake disc having the features of the claim 1 solved.
Eine derartige Bremsscheibe für eine Scheibenbremse eines Kraftwagens umfasst einen Bremsscheibentopf und einen koaxial zu diesem angeordneten Reibring. Erfindungsgemäß ist vorgesehen, dass Bremsscheibentopf und Reibring lösbar über wenigstens ein separates Verbindungselement verbunden und axial sowie radial gegeneinander gesichert sind. Das wenigstens eine separate Verbindungselement korrespondiert dabei mit einem jeweils zugeordneten Formschlusselement des Reibrings und des Bremsscheibentopfes. Hierdurch wird ein stabiler Formschluss zwischen Bremsscheibe und Reibring unter Vermittlung des wenigstens einen Verbindungselementes erzeugt, wobei aufgrund der Lösbarkeit des Verbindungselementes dennoch der Austausch beispielsweise eines durch Verschleiß beeinträchtigten Reibrings ermöglicht ist. Da keine vollständig feste stoffschlüssige Verbindung zwischen den Bauteilen vorliegt, ist noch immer eine axiale bzw. radiale thermische Ausdehnung des Reibrings gegenüber dem Bremsscheibentopf möglich, so dass das Schirmungsverhalten des Reibrings verbessert wird und beim Bremsbetrieb aufgrund der Reibungswärme weniger thermische Spannungen in den Bauteilen induziert werden.A such brake disk for a disc brake of a motor vehicle comprises a brake disc hub and a friction ring disposed coaxially therewith. According to the invention, it is provided that Disc brake disc and friction ring detachable via at least a separate connecting element connected and axially and radially secured against each other. The at least one separate connection element Corresponds to a respectively assigned positive connection element the friction ring and the brake disc pot. This will be a stable Positive connection between brake disc and friction ring under mediation the at least one connecting element generates, due to the solubility the connecting element nevertheless the exchange of a affected by wear Friction ring allows is. Because no complete solid cohesive There is still a connection between the components axial or radial thermal expansion of the friction ring relative to the Brake disc pot possible, so that the shielding behavior of the friction ring is improved and during braking operation due to the frictional heat less thermal stress be induced in the components.
In einer bevorzugten Ausführungsform ist das Verbindungselement als plattenförmiger Mitnehmer ausgebildet. Ein solcher plattenförmiger Mitnehmer greift in jeweils zugeordnete Nuten bzw. Vertiefungen am Bremsscheibentopf und Reibring ein, so dass sich sowohl eine axiale Sicherung als auch eine Drehmomentenübertragung zwischen Bremsscheibentopf und Reibring realisieren lässt. Alternativ kann das Verbindungselement auch als Passfeder, Keil, Nasenkeil oder dergleichen ausgebildet sein.In a preferred embodiment the connecting element is designed as a plate-shaped driver. Such a plate-shaped Driver engages in each associated grooves or depressions at the brake disk pot and friction ring, so that both a axial securing as well as a torque transmission between the brake disc pot and friction ring can be realized. Alternatively, the connecting element as a key, wedge, Nose wedge or the like may be formed.
In einer weiteren bevorzugten Ausführungsform der Erfindung weist das Verbindungselement eine Bohrung auf, in welcher ein Fixierelement zum Fixieren des Verbindungselementes am Reibring und/oder am Bremsscheibentopf aufgenommen ist. Beispielsweise kann die eingangs genannte Ausführungsform eines plattenförmigen Mitnehmers über eine solche Bohrung mittels einer Schraube, eines Stiftes oder eines Bolzens zusätzlich gesichert werden.In a further preferred embodiment the invention, the connecting element has a bore, in which is a fixing element for fixing the connecting element recorded on the friction ring and / or on the brake disk pot. For example can the embodiment mentioned above a plate-shaped Driver over one Such hole by means of a screw, a pin or a Bolzens in addition be secured.
Bevorzugterweise sind mehrere Verbindungselemente vorgesehen, welche axial und/oder radial zueinander beabstandet am Bremsscheibentopf und/oder Reibring angeordnet sind. Hierdurch wird eine verbesserte Verteilung der zwischen Bremsscheibentopf und Reibring wirkenden Kräfte erzielt, so dass die Festigkeit der Verbindung zwischen Bremsscheibentopf und Reibring auf die zu erwartenden zu übertragenden Drehmomente bzw. Axialkräfte optimal angepasst werden können.preferably, a plurality of connecting elements are provided, which axially and / or radially spaced from each other on the brake disk hub and / or friction ring are arranged. As a result, an improved distribution between the brake disc pot and friction-acting forces achieved, so that the strength of the connection between brake disc pot and friction ring on the expected to be transmitted torques or axial forces optimally can be adjusted.
Im Folgenden soll die Erfindung und ihre Ausführungsformen anhand der Zeichnungen näher erläutert werden. Hierbei zeigen:in the Below is the invention and its embodiments with reference to the drawings be explained in more detail. Hereby show:
