Abstract

The brake block (1) has a brake lining (3) and a carrier plate (2). The plate has two projections (6) at opposite ends which are attached to it by intermediate rods (5). The lining also has two projections (3'). These cover at least part of the plate's rod and reach the plate's projections. The lining's projections are preferably stepped or sloped towards their free ends.

Description

Die Erfindung bezieht sich auf eine Bremsbacke der im Oberbegriff des Patentan­ spruchs 1 genannten und beispielsweise aus der DE 43 01 621 A1 hervorgehenden Art.The invention relates to a brake shoe in the preamble of the patent Say 1 and for example from DE 43 01 621 A1.

Eine derartige Bremsbacke besteht aus einer Belagträgerplatte und einem schubfest auf dieser angebrachten Bremsbelag. Dabei hat die Belagträgerplatte zwei, in entgegenge­ setzten Richtungen abstehende, etwa T-förmige Führungen, die jeweils aus einem Zwischensteg und einem rechtwinklig verlaufenden Vorsprung bestehen und üblicher­ weise als "Hammerköpfe" bezeichnet werden. Diese gleiten bei Druckbeaufschlagung der Bremsbacke, also beim Anpressen des Bremsbelags an die Bremsscheibe, jeweils in einer Aufnahmenut des Bremsträgers. Aufgrund der beim Bremsvorgang zwischen dem Bremsbelag und der Bremsscheibe erzeugten Reibung entstehen Bremsge­ räusche, die sich über die hierbei als Körperschallbrücke wirkenden Zwischenstege und Vorsprünge in den Bremsträger fortpflanzen können. Dieser wird dabei durch die Belag­ trägerplatte und deren Vorsprünge zu Resonanzschwingungen angeregt.Such a brake shoe consists of a pad carrier plate and a shear-resistant this attached brake pad. The base plate has two, in opposite set directions protruding, approximately T-shaped guides, each consisting of one Intermediate web and a right-angled projection exist and more common can be referred to as "hammer heads". These slide when pressurized the brake shoe, i.e. when pressing the brake pad against the brake disc, in each case in a receiving groove of the brake carrier. Because of the braking process between the brake lining and the brake disc generated friction are caused by Bremsge noises, which act as a structure-borne sound bridge and Can propagate protrusions in the brake carrier. This is due to the covering carrier plate and its projections excited to resonance vibrations.

Aufgabe der Erfindung ist es daher, eine Bremsbacke der im Oberbegriff des Patentan­ spruchs 1 genannten Art derart auszubilden, daß die beim Bremsvorgang entstehenden Schwingungen vermindert werden.The object of the invention is therefore a brake shoe in the preamble of the patent Say 1 mentioned type in such a way that the resulting during braking Vibrations are reduced.

Zur Lösung der Aufgabe sind die im Patentanspruch 1 dargelegten Merkmale vorge­ sehen. To achieve the object, the features set out in claim 1 are featured see.  

Da der an der Belagträgerplatte vorhandene Bremsbelag sich durch die erfindungs­ gemäß vorgesehenen Fortsätze auch über die Zwischenstege erstreckt, hat die Belag­ trägerplatte insgesamt eine größere Bremsbelagmasse, wodurch vorteilhafterweise die beim Bremsvorgang entstehenden Resonanzschwingungen gedämpft werden. Dabei kann der Bremsbelag im Bereich der beiden Fortsätze in sehr einfacher und kostengün­ stiger Weise verlängert werden.Since the existing on the lining carrier plate brake pad by the Invention according to the projections also extends over the intermediate webs, the covering carrier plate overall a larger brake pad mass, which advantageously the resulting resonance vibrations are damped. Here can the brake pad in the area of the two extensions in a very simple and inexpensive extended way.

Gemäß dem Merkmal des Patentanspruchs 2 verlaufen die beiden Fortsätze des Bremsbelags bis zu den Vorsprüngen der Zwischenstege, so daß deren ganze Längs­ erstreckung mit Bremsbelag bedeckt und damit eine optimale Dämpfungswirkung er­ reicht ist.According to the feature of claim 2, the two extensions of the Brake pads to the projections of the intermediate webs, so that their entire length Extension covered with brake pad and thus an optimal damping effect is enough.

Schließlich sind die beiden Fortsätze des Bremsbelags abgestuft oder zu ihrem freien Ende hin abgeschrägt, so daß in üblicher Weise beim Bremsvorgang der Mittelbereich des Bremsbelags an der Bremsscheibe anliegen kann (Merkmal des Patentanspruchs 3).Finally, the two extensions of the brake pad are graded or free End beveled, so that the central area in the usual manner during braking the brake pad can rest on the brake disc (feature of the claim 3).

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im fol­ genden erläutert. Es zeigt:An embodiment of the invention is shown in the drawing and is in fol explained. It shows:

Fig. 1 eine Bremsbacke in Vorderansicht, Fig. 1 is a brake shoe in front view,

Fig. 2 eine Draufsicht zur Fig. 1. FIG. 2 is a top view of FIG. 1.

Die in den Fig. 1 und 2 dargestellte Bremsbacke 1 dient für eine Scheibenbremse eines Kraftfahrzeugs. Dabei besteht die Bremsbacke 1 aus einer Belagträgerplatte 2 und einem auf dieser schubfest angebrachten Bremsbelag 3.The brake shoe 1 shown in FIGS . 1 and 2 is used for a disc brake of a motor vehicle. The brake shoe 1 consists of a pad carrier plate 2 and a brake pad 3 mounted on it in a thrust-resistant manner.

Wie in Fig. 2 ersichtlich, stehen von der Belagträgerplatte 2 zwei, in entgegenge­ setzten Richtungen weisende Zwischenstege 5 ab, an denen jeweils ein quer zu ihrer Längserstreckung verlaufender Vorsprung 6 ausgebildet ist.As can be seen in FIG. 2, two, in opposite directions, intermediate webs 5 protrude from the lining carrier plate 2 , on each of which a protrusion 6 extending transversely to their longitudinal extension is formed.

In Fig. 2 ist ferner zu ersehen, daß vom Bremsbelag 3 zwei Fortsätze 3′ abstehen, die jeweils über einen Zwischensteg 5 verlaufen und sich dabei bis zu den Vorsprüngen 6 erstrecken. Dabei sind die Fortsätze 3′ jeweils abgestuft ausgebildet (Fig. 1) oder zu ihrem freien Ende hin abgeschrägt.In Fig. 2 it can also be seen that two extensions 3 'protrude from the brake pad 3 , each of which extends over an intermediate web 5 and thereby extend to the projections 6 . The extensions 3 'are each stepped ( Fig. 1) or beveled towards their free end.
