Bremsbacke, insbesondere für Nutzfahrzeug-Scheibenbremsen. Brake shoe, especially for commercial vehicle disc brakes.
Beschreibungdescription
Die Erfindung betrifft eine Bremsbacke, insbesondere fürThe invention relates to a brake shoe, in particular for
Nutzfahrzeug-Scheibenbremsen, die ein Belagmateπal und einen Belagtrager mit Abstutzflachen aufweist und zum Eingriff in einen Bremstrager ausgelegt istCommercial vehicle disc brakes, which has a lining material and a lining carrier with supporting surfaces and is designed for engagement in a brake carrier
Bremsbelagtrager bilden in Verbindung mit einem darauf befestigten Bremsbelagmateπal eine Bremsbacke. Bei Scheibenbremsen wird wahrend einer Bremsung (siehe hierzu z.B. die DE 42 30 005, auf die vollumfanglich verwiesen wird) über den Bremsbelagtrager und das darauf befestigte Bremsbelagmateπal Zuspannkraft weitergeleitet. aus welcher die Bremskraft zwischen Bremsbelag und Bremsscheibe resultiert. Insbesondere im Nutzfahrzeugbereich sind an Bremsbacken hohe Festigkeitsanfordungen zu stelien, denn infoige der großen Fahrzeugmassen treten bei Bremsvorgangen entsprechend hohe Bremskräfte auf Die Bremsbelage werden als hochfeste Teile gefertigt und sind im Belagschacht mit einem gewissen Spiel geführt, so daß die Metaliaußenseiten der Bremsbacke und des Belagtragers u.U störende Geräusche entwickeln können Eine der Anforderungen an eine auch für den Nutzfahrzeugbereich geeignete Bremsbacke ist daher eine möglichst geringe Gerauschentwicklung wahrend des Fahrens oder bei einem EinbremsenBrake pad carriers form a brake shoe in connection with a brake pad material attached to them. In the case of disc brakes, during braking (see, for example, DE 42 30 005, to which reference is made in full), the brake lining carrier and the brake lining material attached to it are passed on. from which the braking force between the brake pad and brake disc results. In the commercial vehicle sector in particular, high strength requirements have to be met on brake shoes, because infoige of the large vehicle masses have correspondingly high braking forces during braking being able to develop disturbing noises One of the requirements for a brake shoe that is also suitable for the commercial vehicle sector is therefore the lowest possible noise development during driving or when braking
Die Erfindung zielt darauf ab, eine unkompliziert herstellbare Bremsbacke zu schaffen, die auch im Dauerbetrieb nur eine geringe Gerauschentwicklung verursacht Die Erfindung erreicht dieses Ziel durch den Gegenstand des Anpruches 1 Eine Grundidee der Erfindung besteht demnach dann, den gattungsgemaßeπ Bremsbelag bzw die gattungsgemaße Bremsbacke derart auszulegen, daß der Belagtrager ein zumindest begrenzt elastisches Abstutzelemeπt aufweist Das Abstutzelement ist bzgl. des Materiales und der Geometrie derart auslegbar, daß die Gerauscheπtwicklung durch aufeinandertreffende Teile - besonders im gelosten Zustand der Bremse - deutlich vermindert wird Die Erfindung mindert insbesondere die Gerauschentwicklung zwischen Belagtrager und Bremstrager, wobei im Gegensatz zu den bekannten Dammplatten für PKW-Belage auch die Gerauschentwickluπg im Seitenbereich der Belage im Belagschacht vermindert wirdThe invention aims to provide a brake shoe that is easy to manufacture and that causes only a low level of noise even in continuous operation The invention achieves this goal by the subject matter of claim 1. A basic idea of the invention is therefore to design the generic brake pad or the generic brake shoe in such a way that the pad carrier has an at least limited elastic support element. The support element can be designed in this way with regard to the material and the geometry That the noise development is significantly reduced by colliding parts - especially when the brake is released. The invention particularly reduces the noise development between the lining carrier and the brake carrier, whereby, in contrast to the known dam plates for car linings, the noise development in the side area of the lining in the lining shaft is also reduced becomes
Bei einer besonαers bevorzugten Variante der Erfindung ist das Abstutzelement im Belagtrager abgestutzt, es ragt über die Abstutzflachen hinaus, es stutzt sich am Bremstrager ab und es ist in Richtung des Bremsmomeπtes und/oder in Richtung Auflagekraft der Bremsbacke elastisch verformbar. Mit dieser Variante αer Erfindung ist die Gerauschuπterdruckung besonders gut realisierbar, wobei die Elastizität derart bemessen sein sollte, daß das Abstutzelement beim Bremsen etwas zusammengedruckt wird und so das Abstutzen der metallischen Abstutzflachen der Belage und des Bremstragers beim Bremsen nicht behindert Das Abstutzelement wird dann nur mit einer definierten elastischen Kraft und nicht mit αer vollen Auflagekraft und/oder Kraftresultierendeπ aus dem Bremsmσment belastetIn a particularly preferred variant of the invention, the support element is supported in the lining carrier, it protrudes beyond the support surfaces, it is supported on the brake carrier and it is elastically deformable in the direction of the braking torque and / or in the direction of the contact pressure of the brake shoe. With this variant of the invention, the noise pressure can be implemented particularly well, the elasticity should be such that the support element is compressed somewhat during braking and thus does not hinder the support of the metallic support surfaces of the pads and the brake support during braking. The support element is then only with a defined elastic force and not loaded with a full contact force and / or force resultant from the braking torque

Zunächst sei Fig 1 beschrieben Fig 1 a zeigt eine Draufsicht auf eine Bremsbacke 1 für Nutzfahrzeug-Scheibenbremsen, die einen aus zwei Einzelplatten 2a, 2b zusammengesetzten Belagtrager 2 und ein Belagmatenal 3, wobei sich der Belagtrager 2 mit (metallischen) Abstutzflachen 4 bei Bremsungen seitlich am Belagtrager 6 (siehe Fig 4) abstutzt Die Belagtragerpiatte 2b ist zur Geräuschdämpfung mit einem Abstutzelement 5 (Gummi, Elastomer) versehen welches mit einem Ansatz 5a auch in die Belagtragerpiatte 2a eingreift Insgesamt sollte die Verbindung zwischen dem Belagtrager 2 (oder ggf auch dem Belagmatenal 3) und dem Abstutzelemeπt 5 derart ausgelegt sein, daß das Abstutzelement 5 leicht und unkompliziert ausgetauscht werden kann (z B Verschraubung, Vernieruπg) Bei vereinfachten Ausfuhrungsformen sind alternativ auch Verklebuπgen und/oder Mateπalverpressungen denkbar1 a shows a plan view of a brake shoe 1 for commercial vehicle disc brakes, the lining carrier 2 composed of two individual plates 2a, 2b and a lining material 3, the lining carrier 2 with (metallic) support surfaces 4 during braking supported on the lining carrier 6 (see FIG. 4) The lining carrier plates 2b are provided with a supporting element 5 (rubber, elastomer) for noise reduction, which also engages with the lining carrier plates 2a with a projection 5a. Overall, the connection between the lining carrier 2 (or, if applicable, the lining material) should 3) and the support element 5 can be designed in such a way that the support element 5 can be replaced easily and uncomplicatedly (for example screwing, vernieruπg). In the case of simplified embodiments, gluing and / or material pressing are alternatively conceivable
Wie in Fig 1 zu erkennen, ragt das Abstutzelement 5 im gelosten Zustand der Bremse leicht über die Abstutzflachen 4 der Belagtragerpiatte 2 hinaus (einige mm) und es ist (in Draufsicht) nahezu rechteckig ausgebildet (mit abgeschrägten Ecken) Das Abstutzelement greift jeweils in Ausnehmuπgen 9 ein, die in den Ecken einer der Platten 2b des Belagtragers 2a ausgespart sind Damit ergiDt sich auch bei gelöster Bremse in zwei zueinander senkrechten Bewegungsrichtungen eine gerauschdammende Wirkung Das Abstutzelement 5 ist ferner so ausgelegt, daß bei einem vollen Verformungsweg des Abstutzelementes 5 die Abstutzflache 4 des Belagtragers 2 voll mit dem Bremstrager 6 in Wirkung steht Das Abstutzelement 5 weist darüberhinaus bevorzugt in Richtung der Zuspannkraft eine federnde Wirkung auf, wobei die Abstutzflache 4 als Begrenzung der elastischen Verformung des Abstutzelementes 5 wirkt und eine Art Festanschlag bildetAs can be seen in FIG. 1, the support element 5, when the brake is released, protrudes slightly beyond the support surfaces 4 of the lining carrier plate 2 (a few mm) and (in plan view) it is almost rectangular (with beveled corners). The support element engages in recesses 9, which are recessed in the corners of one of the plates 2b of the lining carrier 2a, so that there is a noise-reducing effect even when the brake is released in two mutually perpendicular directions of movement. The support element 5 is also designed such that the support surface 4 is at a full deformation path of the support element 5 of the lining carrier 2 is fully in effect with the brake support 6. The support element 5 also preferably has a resilient effect in the direction of the application force, the support surface 4 acting as a limitation of the elastic deformation of the support element 5 and forming a kind of fixed stop
Bei dem Ausfuhrungsbeispiel der Fig 2 ist das Abstutzelement 5 als VerDundteil ausgestaltet, das einen im wesentlichen federnden und/oder damprenden Bereich, der als Elastoelement 51 ausgeführt ist, und einen im wesentlichen festen, reibungsarmen Bereich, der ais Gleitelement 52 ausgelegt ist, aufweist Hiervon unterscheidet sich das Aufuhrungsbeispiel der Fig 3 zur Erzielung gunstiger Temperatureigenschaften dadurch, daß zwischen Abstutzeiement 5 und Belagtrager 2 ein Abschirmelement 7 angeordnet ist Bevorzugt besteht das Abschirmeiement 7 aus einem temperaturfesten Mateπal, und/oder es wird ein Material gewählt das eine geringe Wärmeleitfähigkeit aufweistIn the exemplary embodiment in FIG. 2, the support element 5 is designed as a sealing part which has an essentially resilient and / or damaging area, which is designed as an elasto element 51, and an essentially solid, low-friction area, which is designed as a sliding element 52 3 differs from this in order to achieve favorable temperature properties in that a shielding element 7 is arranged between the support element 5 and the lining carrier 2. The shielding element 7 preferably consists of a temperature-resistant material, and / or a material is selected which has a low thermal conductivity
Eine fertigungstechnisch besonders vorteilhafte Variante der Erfindung zeichnet sich ferner dadurch aus, daß das Abstutzelement 5 und das Abschirmelement 7 als ein integriertes Kompaktteil 8 ausgebildet sindA variant of the invention that is particularly advantageous in terms of production technology is further characterized in that the support element 5 and the shielding element 7 are designed as an integrated compact part 8
