Abstract
Description
Bei der Erfindung wird ausgegangen von einer Radbremse für ein Kraftfahrzeug, gemäß Oberbegriff des Patentanspruchs 1. In the invention it is assumed that a wheel brake for a motor vehicle, according to the preamble of patent claim 1.
Eine solche Radbremse ist aus der
Aufgabe der Erfindung ist es, eine Radbremse der eingangs genannten Art anzugeben, bei der die Dämpfungslage ausreichend vor einem Wärmeeintrag geschützt ist und die sich außerdem durch eine höhere Wartungsfreundlichkeit auszeichnet. The object of the invention is to provide a wheel brake of the type mentioned, in which the damping layer is sufficiently protected against heat input and also characterized by a higher ease of maintenance.
Gelöst wird diese Aufgabe mit einer Radbremse, die die im Patentanspruch 1 genannten Merkmale aufweist. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. This object is achieved with a wheel brake, which has the features mentioned in claim 1. Further developments of the invention are the subject of the dependent claims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zusehen, dass durch die Ausbildung der Dämpfungslage als Dämpfungsplatte und der Wärmeisolierung als Wärmeisolierkörper als separate Bauteile, also unabhängig von dem Bremsklotz, und durch die Befestigung der Dämpfungsplatte ausschließlich an dem Bremskolben einerseits der Wärmeeintrag in die Dämpfungsplatte über den Reibbelag und dem Reibbelagträger durch den Wärmeisolierkörper verringert ist und andererseits durch den direkten Kontakt zwischen Dämpfungsplatte und Bremskolben die Dämpfungsplatte durch den Bremskolben quasi einen Kühlkörper erhält. Außerdem ist vorteilhaft, dass zusammen mit dem Bremsklotz weder die Dämpfungsplatte noch der Wärmeisolierkörper getauscht werden müssen, da sie nicht mit dem Bremsklotz verbunden sind. Durch diese erfindungsgemäße Anordnung wird die Dämpfungsplatte einer wesentlich geringeren Temperaturbelastung ausgesetzt, als dies im Stand der Technik gegeben ist. Damit behält die Dämpfungsplatte ihre Geräuschdämpfungseigenschaften über einen langen Zeitraum und muss nicht mit jedem Bremsklotzwechsel getauscht werden. Damit ergibt sich über die sehr lange Lebenszeit der Dämpfungsplatte eine Geräuschdämpfung, wodurch insbesondere das so genannte Bremsenquietschen auf eine lange Zeitdauer zumindest verringert werden kann. Durch die erfindungsgemäße Ausgestaltung von Dämpfungsplatte und Wärmeisolierkörper bildet der Wärmeisolierkörper gleichzeitig eine Tilgermasse für den Bremsklotz, wodurch eine weitere Geräuschdämpfung der Radbremse erreicht wird. Die Bremsscheibe kann vorzugsweise als Keramikscheibe oder alternativ als Stahlscheibe ausgeführt sein. The advantages achieved by the invention are to be seen in that by the formation of the damping layer as a damping plate and the heat insulation as Wärmeisolierkörper as separate components, ie independent of the brake pad, and by attaching the damping plate only on the brake piston on the one hand, the heat input into the damping plate is reduced by the heat insulating over the friction lining and the Reibbelagträger and on the other hand receives the damping plate through the brake piston quasi a heat sink by the direct contact between the damping plate and the brake piston. It is also advantageous that, together with the brake pad, neither the damping plate nor the heat insulating body must be replaced, since they are not connected to the brake pad. By this arrangement according to the invention the damping plate is exposed to a much lower temperature load, as is given in the prior art. Thus, the damping plate maintains its noise damping properties over a long period of time and does not have to be replaced with each brake pad change. This results in a noise attenuation over the very long life of the damping plate, which in particular the so-called brake squeal can be reduced to a long period of time at least. Due to the inventive design of the damping plate and Wärmeisolierkörper the Wärmeisolierkörper simultaneously forms a damping mass for the brake pad, creating a further noise reduction of the wheel is achieved. The brake disk can preferably be designed as a ceramic disk or alternatively as a steel disk.
Bevorzugt wird bei einer Weiterbildung der Erfindung die Dämpfungsplatte als Sandwichbauteil aufgebaut sein, wobei zumindest eine Gummi- und/oder Klebeschicht beidseitig von Metallplatten bedeckt sind. Gegebenenfalls kann die Dämpfungsplatte auch mehrere Gummi- und/oder Klebeschichten und eine entsprechend höhere Anzahl von Metallplatten aufweisen. Preferably, in a development of the invention, the damping plate be constructed as a sandwich component, wherein at least one rubber and / or adhesive layer are covered on both sides by metal plates. Optionally, the damping plate may also have a plurality of rubber and / or adhesive layers and a correspondingly higher number of metal plates.
Nach einer Weiterbildung der Erfindung wird besonders bevorzugt der Wärmeisolierkörper als Phenolharzkörper oder Zirkonoxidkörper ausgebildet sein. Diese Materialien sind als separate Bauteile besonders einfach herstellbar und weisen eine gute Wärmeisolierung auf. According to a development of the invention, the heat insulation body is particularly preferably designed as a phenolic resin body or zirconia body. These materials are particularly easy to produce as separate components and have good thermal insulation.
Besonders bevorzugt wird weiterhin eine Ausführungsform, bei der der Bremskolben eine Ausnehmung aufweist, in die die Dämpfungsplatte eingesetzt ist. Vorzugsweise wird die Dämpfungsplatte in der Ausnehmung mit dem Bremskolben verklebt. Dabei ist in einer bevorzugten Ausführungsform die Tiefe der Ausnehmung so bemessen, dass die Dämpfungsplatte zumindest teilweise aufgenommen werden kann. Es ist jedoch auch möglich, die Tiefe der Ausnehmung so zu gestalten, dass die Dämpfungsplatte vollständig und auch der Wärmeisolierkörper teilweise aufgenommen werden können. Particularly preferred is still an embodiment in which the brake piston has a recess into which the damping plate is inserted. Preferably, the damping plate is glued in the recess with the brake piston. In this case, in a preferred embodiment, the depth of the recess is dimensioned such that the damping plate can be at least partially accommodated. However, it is also possible to make the depth of the recess so that the damping plate can be completely and also partially absorbed by the heat insulating body.

Es ergibt sich somit eine Anordnung der Radbremse
