Description

Bremsbelag für eine Scheibenbremse  Brake pad for a disc brake
Die Erfindung betrifft einen Bremsbelag für eine Scheibenbremse nach dem Oberbegriff des Anspruchs 1 . Derartige Bremsbeläge kommen sowohl bei Scheibenbremsen für Personenkraftwagen wie auch für Nutzfahrzeuge zum Einsatz. Dabei besteht der Bremsbelag aus einer Belagträgerplatte sowie einem darauf befestigten Reibbelag, der im Fall einer Bremsung gegen eine rotierende Bremsscheibe gepresst wird. Die Belagträgerplatte, auf die der Reibbelag üblicherweise durch Pressen aufgebracht ist, dient zum einen der Verteilung von Zuspannkräften, die beim The invention relates to a brake pad for a disc brake according to the preamble of claim 1. Such brake pads are used both in disc brakes for passenger cars as well as for commercial vehicles. Here, the brake pad consists of a lining carrier plate and a friction lining mounted thereon, which is pressed in the case of braking against a rotating brake disc. The pad carrier plate to which the friction lining is usually applied by pressing, serves on the one hand, the distribution of application forces, the
Bremsen mittels einer Zuspanneinrichtung aufgebracht werden und zum anderen zur Übertragung von beim Bremsen entstehenden Bremsmomenten auf beispielsweise Bremsträgerhörner, die einen Belagschacht, in dem der Brems- belag positioniert ist, eines ortsfesten Bremsträgers begrenzen. Brakes are applied by means of an application device and on the other hand for the transmission of braking torques arising during braking on, for example, brake carrier horns, which delimit a lining shaft in which the brake lining is positioned, of a stationary brake carrier.
Insbesondere bei Nutzfahrzeugen sind wegen der hohen umzusetzenden Especially in commercial vehicles are because of the high to be implemented
Bremsenergien große, schwere Bremsbeläge mit entsprechend massiven Belagträgerplatten erforderlich, was nicht nur wegen der relativ großen ungefeder- ten Masse als nachteilig angesehen wird, sondern auch der stetigen Forderung nach einer Gewichtsoptimierung aller Bauteile entgegensteht. Brake energy large, heavy brake pads with correspondingly solid lining carrier plates required, which is not only considered disadvantageous because of the relatively large unsprung mass, but also counteracts the steady demand for weight optimization of all components.
Überdies kommt es im Fahrbetrieb aufgrund der auftretenden Erschütterungen zu einer als äußerst störend empfundenen Geräuschentwicklung, da die aus Metall, insbesondere aus Gusseisen oder Stahlblech gefertigten Belagträgerplatten gegen metallische Stützteile der Scheibenbremse schlagen. Moreover, it comes in driving due to the vibrations occurring at a perceived as extremely disturbing noise, since the made of metal, in particular made of cast iron or sheet steel pad carrier plates strike against metallic support members of the disc brake.
Der Erfindung liegt die Aufgabe zugrunde, einen Bremsbelag der gattungsgemäßen Art so weiterzuentwickeln, dass er bei unveränderter Betriebssicherheit ge- wichtsoptimiert ist und sein Betriebsverhalten verbessert wird. The invention has for its object to develop a brake pad of the generic type so that it is weight-optimized weight with unchanged reliability and its performance is improved.
Diese Aufgabe wird durch einen Bremsbelag mit den Merkmalen des Anspruchs 1 gelöst. Dieser Bremsbelag zeichnet sich zunächst einmal dadurch aus, dass der biegesteife Kern, der aus Metall, wie Aluminium, Stahl oder Guss bestehen kann, aber auch aus beispielsweise einem faserverstärkten Material wie Karbon oder dergleichen, exakt dem Belastungsverlauf beim Bremsen angepasst bzw. dimensio- niert werden kann, während die übrigen Bereiche, die nicht oder nur gering belastet sind, aus der aus einem zur Einbettung des Kerns plastifizierbaren Material bestehenden Schicht gebildet werden, die wenigstens einseitig zu einer Platte geformt ist. Bevorzugt besteht dieses Material aus einem polymeren oder elastomeren Kunststoff, der den Kern zumindest teilweise umhüllt, wobei die kraftübertragenden Flächen selbst nicht beschichtet sind. Denkbar ist aber auch, diese Umhüllung aus dem Material zu bilden, aus dem der Reibbelag besteht, der nach dem Einsetzen des Kerns in die plastifizierte Reibbelagmasse durch Sintern entsteht. This object is achieved by a brake pad with the features of claim 1. This brake lining is initially characterized by the fact that the rigid core, which may consist of metal, such as aluminum, steel or cast iron, but also, for example, a fiber-reinforced material such as carbon or the like, exactly adapted to the load curve during braking or dimensioned can be made, while the remaining areas that are not or only slightly loaded, are formed from the existing of a material for embedding the core plasticizable layer which is formed at least one side to a plate. Preferably, this material consists of a polymeric or elastomeric plastic, which at least partially surrounds the core, wherein the force-transmitting surfaces themselves are not coated. It is also conceivable, however, to form this envelope from the material constituting the friction lining which is produced by sintering after insertion of the core into the plastified friction lining mass.
Der Kern selber, der, wie erwähnt, ausschließlich belastungsoptimiert gestaltet ist, kann in Form eines Fachwerkes, als Wabenstruktur oder als geeignete, dünn ver- rippte Platte ausgebildet sein. Dadurch wird die Übertragung auch der beim Bremsen auftretenden hohen Kräfte bei äußerst geringem Gewicht möglich. The core itself, which, as mentioned, is designed exclusively to optimize the load, can be designed in the form of a framework, as a honeycomb structure or as a suitable, thinly ribbed plate. As a result, the transmission of the high forces occurring during braking at extremely low weight is possible.
Wie sich gezeigt hat, ist durch die sozusagen Verbund-Belagträgerplatte eine Gewichtseinsparung pro Scheibenbremse von bis zu 1 Kilogramm möglich, bei einer 22,5" Scheibenbremse. Hieraus ergibt sich eine entsprechende Erhöhung der Nutzlast sowie eine Verringerung der ungefederten Massen. Die Gewichtsre- duzierung führt andererseits zu einer Kraftstoffersparnis, so dass sich insgesamt betriebswirtschaftliche Vorteile ergeben. As has been shown, the so-called composite lining carrier plate allows a weight saving per disc brake of up to 1 kilogram, with a 22.5 "disc brake, resulting in a corresponding increase in payload and a reduction in unsprung masses On the other hand leads to fuel savings, so that overall business benefits arise.
Ein weiterer durchaus bemerkenswerter und angestrebter Effekt ist ebenfalls durch die Erfindung realisiert. Durch eine an die jeweilige Achskonstruktion ange- paßte und optimierte Formgebung des metallischen Kerns ist es möglich, für die Geräuschbildung kritische Anregungsfrequenzen in unkritische Bereiche zu verschieben, was zu einer Verbesserung des sogenannten NVH-Verhaltens führen kann. Zudem wirkt die umgebende Kunststoffschicht zusätzlich dämpfend. Zur Herstellung des neuen Bremsbelags sind verschiedene Fertigungsmethoden denkbar. So kann der Belagträger, d.h. der vorzugsweise metallische Kern einschließlich der Beschichtung separat gefertigt und der Reibbelag als Kuchen anschließend, wie bisher, unter hohem Druck aufgepresst bzw. geklebt werden. Da- bei bildet die Besch ichtung eine, wenngleich dünne planebene Fläche, an der de Reibbelag anliegt. Another quite remarkable and desired effect is also realized by the invention. By adapting and optimizing the shape of the metallic core to the respective axle construction, it is possible to shift critical excitation frequencies into uncritical regions for noise generation, which can lead to an improvement in the so-called NVH behavior. In addition, the surrounding plastic layer has an additional damping effect. For the production of the new brake pad various production methods are conceivable. Thus, the lining carrier, ie the preferably metallic core including the coating can be made separately and then the friction lining as a cake, as before, pressed or glued under high pressure. There- In the case of the coating, the coating forms a plane surface, albeit thin, on which the friction lining bears.
Denkbar ist jedoch auch, den Kern als Einlegeteil zu verwenden und ihn in einem Fertigungsschritt mit der Schicht und der Reibmasse zu versehen. Alternativ kann der Kern auch ohne Kunststoffbeschichtung in das Reibmaterial eingebettet werden. However, it is also conceivable to use the core as an insert and to provide it in a manufacturing step with the layer and the friction mass. Alternatively, the core can also be embedded without plastic coating in the friction material.
Nach einem weiteren Gedanken wird der Kern auf den bereits vorgefertigten Reibbelag aufgebracht und die Schicht anschließend in eine Form, in der sich die Einheit Reibbelag/Kern befindet, eingegossen oder eingespritzt. According to another idea, the core is applied to the already prefabricated friction lining and then the layer in a mold in which the unit friction lining / core is cast or injected.
Der Kern selbst kann als Stanzteil ausgebildet sein oder als Umform- und/oder Blechbiegeteil. Selbstverständlich besteht auch die Möglichkeit, den Kern durch Gießen herzustellen. In jedem Fall ist der Kern als Serienteil zu fertigen, wobei durch die belastungsoptimierte Gestaltung der Materialeinsatz auf das tatsächlich notwendige Maß beschränkt ist, wodurch sich naturgemäß eine sehr kostengünstige Herstellung ergibt. Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. The core itself may be formed as a stamped part or as a forming and / or sheet metal part. Of course, there is also the possibility to produce the core by casting. In any case, the core is to be manufactured as a series part, wherein the use of material optimized by the load-optimized design is limited to the actual necessary level, which naturally results in a very cost-effective production. Further advantageous embodiments of the invention are characterized in the subclaims.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben. An embodiment of the invention will be described below with reference to the accompanying drawings.
Es zeigen: Show it:

Bremsbelages, jeweils in einer perspektivischen Ansicht.  Brake pads, each in a perspective view.
In der Figur 1 ist ein biegesteifer Kern 2 eines Belagträgers 1 als vorgefertigtes, beispielsweise aus Metall bestehendes Teil dargestellt, das belastungsoptimiert gestaltet ist und zwei abständig zueinander angeordnete Anlageflächen für Bremsstempel einer Zuspanneinrichtung einer Scheibenbremse bildenden Augen 3 aufweist, die durch zwei Stege 4 miteinander verbunden sind. In Figure 1, a rigid core 2 of a lining carrier 1 is shown as prefabricated, for example made of metal part, which is designed optimized load and two spaced apart arranged abutment surfaces for brake piston Zuspanneinrichtung a disc brake forming eyes 3, which are interconnected by two webs 4 are.
An der Unterseite des Kerns 2, im Außenrandbereich sind zwei Auflager 9 angeformt, mit denen der Bremsbelag in Funktion am Grund eines Belagschachtes eines Bremsträgers aufsteht. Im rechten Winkel dazu angeordnet, den Kern 2 bzw. den Belagträger 1 seitlich begrenzend, sind Anlageleisten 8 vorgesehen, die sich an Bremsträgerhörnern des Bremsträgers abstützen. On the underside of the core 2, in the outer edge region of two supports 9 are formed, with which the brake pad in function at the bottom of a lining shaft of a brake carrier stands up. Arranged at right angles to the core 2 or the lining carrier 1 laterally limiting, bearing strips 8 are provided, which are supported on brake carrier horns of the brake carrier.
Auf der den Auflagern 9 gegenüberliegenden Seite sind, jedem Auge 3 zugeordnet, Haltelaschen 5 angeformt, während benachbart, mittig angeordnet ein Halter 6 vorgesehen ist, mit einer Durchgangsöffnung 7. In der Figur 2 ist der Kern mit einer Schicht 10 dargestellt, die bevorzugt aus einem Kunststoff, vor allem einem Elastomer besteht und in plastifizierter Form aufgetragen ist. Dabei umhüllt die Schicht 10 den Kern 2 teilweise, wobei die Augen 3 ebenso wie die Stege 4 auf einer Seite frei liegen, ebenso wie die Auflager 9 und die Anlageleisten 8. On the opposite side of the supports 9, retaining lugs 5 are formed, associated with each eye 3, while adjacent, centrally arranged a holder 6 is provided with a through opening 7. In the figure 2, the core is shown with a layer 10, preferably made of a plastic, especially an elastomer and is applied in plasticized form. In this case, the layer 10 partially encloses the core 2, wherein the eyes 3 as well as the webs 4 are exposed on one side, as well as the supports 9 and the contact strips 8.
Im Übrigen entspricht der Belagträger 1 in seiner Form dem Belagträger, wie er aus dem Stand der Technik bekannt ist. D.h., er bildet eine Anlagefläche für einen Reibbelag 1 1 , der in der Figur 3 erkennbar ist, in der ein komplettierter Bremsbelag dargestellt ist. Incidentally, the lining carrier 1 corresponds in shape to the lining carrier, as is known from the prior art. That is, it forms a contact surface for a friction lining 1 1, which can be seen in the figure 3, in which a completed brake pad is shown.
Neben dem Reibbelag 1 1 ist eine Belaghaltefeder 12 an den Laschen 5 befestigt, wobei die Öffnung 7 einen Eingriff für die Belaghaltefeder 12, die ebenso wie der Reibbelag 1 1 der Einfachheit halber nur teilweise gezeigt ist, bildet, so dass die Belaghaltefeder 12 unverlierbar am Belagträger 1 gehalten wird. In addition to the friction lining 1 1, a pad retaining spring 12 is attached to the tabs 5, wherein the opening 7 an engagement for the pad retaining spring 12, which as well as the friction pad 1 1 is shown for the sake of simplicity only partially forms, so that the pad retaining spring 12 captive on Pad carrier 1 is held.
Auf seiner dem Reibbelag 1 1 zugewandten Seite sind am Kern 2 Formschlussmittel in Form von Stiften, Bolzen, aufgeschweißten oder aufgenieteten Streckgittern oder als Sinterraugrund angeordnet, zur Befestigung des Reibbelages 1 1 . Solche Formschlusselemente können auch an der Schicht 10 vorgesehen sein, an der der Reibbelag 1 1 unmittelbar angeschlossen ist. On its side facing the friction lining 1 1 are on the core 2 positive locking means in the form of pins, bolts, welded or riveted expanded metal or arranged as Sinterraugrund for attachment of the friction lining 1 first Such form-fitting elements can also be provided on the layer 10 to which the friction lining 1 1 is directly connected.
