Abstract
Bremsscheibe für eine Scheibenbremse, insbesondere eines Kraftfahrzeugs, deren Reibflächen aufweisende Bremsscheibe aus einem Verbundwerkstoff, z. B. Kohlenstofffaserverstärktem, porösem Kohlenstoffkörper besteht, dadurch gekennzeichnet, dass zumindest an einer zugänglichen Reibfläche (10) der Bremsscheibe (3) ein Belastungsindikator (12) vorgesehen ist, der dem Fahrer oder einem Servicezuständigen Hinweise über etwaige Zustandsänderungen der Bremsscheibe (3), insbesondere durch Temperatureinwirkung, gibt, wobei der Belastungsindikator (12) wenigstens ein Flächenelement (13, 22, 23, 24, 25) aus einem nicht oxidationsgeschützten Werkstoff umfasst, das in die Reibfläche (10) zwischen einer radial äußeren Ringbegrenzung (5) und einer radial inneren Ringbegrenzung (6) der Bremsscheibe (3) oberflächenbündig eingesetzt ist.Brake disc for a disc brake, in particular a motor vehicle whose friction surfaces having brake disc of a composite material, for. B. carbon fiber reinforced, porous carbon body is, characterized in that at least on an accessible friction surface (10) of the brake disc (3) a load indicator (12) is provided to the driver or a service-competent notes about any changes in state of the brake disc (3), in particular by the effect of temperature, wherein the load indicator (12) comprises at least one surface element (13, 22, 23, 24, 25) of a non-oxidation-protected material in the friction surface (10) between a radially outer ring boundary (5) and a radial inner ring boundary (6) of the brake disc (3) is inserted flush with the surface.
Description
Die Erfindung bezieht sich auf einen Reibkörper, vorzugsweise Bremsscheibe für eine Scheibenbremse nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a friction body, preferably brake disc for a disc brake according to the preamble of patent claim 1.
Eine bekannte Bremsscheibe einer Scheibenbremse aus keramischem Werkstoff,
Aus der
Bremsscheiben der vorgenannten Art weisen eine höhere Stand- und Verschleißfestigkeit als solche z. B. aus eisenmetallischem Werkstoff auf und werden in der Öffentlichkeit – DE ”EIN SONDERTHEMA DER STUTTGARTER NACHRICHTEN UND DER STUTTGARTER ZEITUNG” März AUTO 2001; Freitag, 2. März 2001, Seite 3 – aufgrund der besonderen Eigenschaften entsprechend positiv dargestellt.Brake discs of the aforementioned type have a higher stability and wear resistance than such z. Made of iron-metallic material and are made public - DE "A SPECIAL TOPIC OF THE STUTTGARTER NEWS AND THE STUTTGARTTER ZEITUNG" März AUTO 2001; Friday, March 2, 2001, page 3 - due to the special features shown as positive.
Allerdings weisen besagte keramische Bremsscheiben keine Einrichtungen auf, die einen Hinweis auf eventuelle Überbeanspruchungen der Bremsscheiben, insbesondere durch Wärmeeinwirkungen wiedergeben. Solche Überbeanspruchungen können unter Umständen zur Ausgasung von Kohlenstofffasern und damit zur Schwächung der Trägerstruktur der Bremsscheibe führen.However, said ceramic brake discs have no facilities that give an indication of any overuse of the brake discs, especially by heat. Under certain circumstances, such overstresses can lead to the outgassing of carbon fibers and thus to the weakening of the carrier structure of the brake disk.
Die
Die
Aufgabe der Erfindung ist es, an der Bremsscheibe solche Vorkehrungen zu treffen, dass vor allem extreme Temperaturbeanspruchungen an der Bremsscheibe aus keramischem Werkstoff feststellbar sind.The object of the invention is to take such precautions on the brake disc that especially extreme temperature stresses on the brake disc made of ceramic material can be detected.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention, this object is solved by the features of patent claim 1. Further, the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass der Belastungsindikator dem Fahrer, Servicezuständigen oder dergl. sachdienliche, beispielsweise visuelle Hinweise z. B. von Extrembelastungen der Bremsscheibe aus keramischem Werkstoff gibt. Dabei umfasst der Belastungsindikator erfindungsgemäß ein in die Reibfläche der Bremsscheibe integriertes Flächenelement, das infolge von Extrembelastungen sich sichtbar verändert oder auch auf- bzw. ablöst und damit eine Anzeigefunktion ausübt. Das im Aufbau einfache Flächenelement aus einem nicht oxidationsgeschützten Werkstoff kann z. B. aus Graphit oder dergl. bestehen und lässt sich leicht sowie mit geeigneten Maßnahmen an der Bremsscheibe befestigen.The advantages achieved by the invention are to be seen in the fact that the load indicator to the driver, service or the like. Pertinent, such as visual cues z. B. of extreme loads of the brake disc made of ceramic material. According to the invention, the load indicator comprises a surface element which is integrated into the friction surface of the brake disk and which visibly changes as a result of extreme loads or also lifts or releases and thus exerts a display function. The simple in construction surface element of a non-oxidation-protected material may, for. B. graphite or the like. Consist and can be easily and with appropriate measures attached to the brake disc.
Soweit die Bremsscheibe mit evolventenförmigen Kühlkanälen zur Innenbelüftung versehen ist, ist es baulich vorteilhaft, wenn das Flächenelement im Bereich eines der Stege angeordnet ist, die die Kühlkanäle voneinander trennen. Schließlich ist es zur Erkennung des Flächenelements günstig, wenn es benachbart der äußeren Ringbegrenzung der Bremsscheibe angeordnet ist, Kreisform aufweist und gegenüber der Reibscheibe farblich abgesetzt ist.As far as the brake disc is provided with involute cooling channels for internal ventilation, it is structurally advantageous if the surface element is arranged in the region of one of the webs, which separate the cooling channels from each other. Finally, it is favorable for the detection of the surface element, if it is arranged adjacent to the outer ring boundary of the brake disc, has a circular shape and is offset in color from the friction disc.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher beschrieben ist.In the drawing, an embodiment of the invention is shown, which is described in more detail below.
