Description

Scheibenbremse für ein Nutzfahrzeug  Disc brake for a commercial vehicle
Die Erfindung betrifft eine Scheibenbremse für ein Nutzfahrzeug nach dem Oberbegriff des Anspruchs 1 . The invention relates to a disc brake for a commercial vehicle according to the preamble of claim 1.
In Funktion, also bei einer Bremsung, wird mittels eines pneumatisch oder elektromotorisch verschwenkbaren Bremshebels über eine im Bremssattel in Richtung der Bremsscheibe verschieblich gelagerte Brücke ein Bremsbelag gegen die Bremsscheibe gepresst, wobei in der Brücke Stellspindeln gehalten sind, mit endseitig angeschlossenen Druckstücken, die am Bremsbelag anliegen. In function, ie during braking, a brake pad is pressed against the brake disc by means of a pneumatically or electromotively pivotable brake lever via a slidably mounted in the brake caliper bridge in the direction of the brake disc, being held in the bridge adjusting spindles, with end-connected pressure pads on the brake pad issue.
Die Verschiebung der Brücke im Bremssattel erfolgt geführt, wozu die sich quer zur Zuspannrichtung gegenüberliegenden, den Stellspindeln der Brücke zugeordneten Seitenwände des Bremssattels in Korrespondenz mit den zugeordneten Außenflächen der Brücke dienen. Dabei schließen die halbschalenformigen Führungsbahnen des Bremssattels jeweils einen Winkel von etwa 180° ein. Der Bremshebel ist als Exzenterhebel ausgebildet und stützt sich im Bereich seines Exzenters zum einen an der Brücke und zum anderen am Rücken des Bremssattels ab, wobei üblicherweise an der Brücke eine Wälzrolle angeordnet ist, die als Lagerung für den Bremshebel fungiert. Insbesondere um ein bei der Schwenkbewegung des Bremshebels, verursacht durch die Exzentrität, sich ergebendes Kippen der Brücke zu ermöglichen, ohne dass diese sich in den Führungsbahnen verspannt, ist eine der Führungen als Fest- und die andere als Loslager ausgebildet. Hierzu ist der loslagerseitige Außenradius der Brücke, der in Korrespondenz steht mit der Wandung des Bremssattels, kleiner als der Krümmungsradius der Bremssattelwand, so dass ein Ausweichen der Brücke bei der Betätigung des Bremshebels, d.h. bei einem axialen Verschieben in Richtung der Bremsscheibe möglich ist. The displacement of the bridge in the brake caliper is done, including the transverse to the application direction, the adjusting spindles of the bridge associated side walls of the caliper serve in correspondence with the associated outer surfaces of the bridge. The half-shell-shaped guideways of the caliper each enclose an angle of about 180 °. The brake lever is designed as an eccentric lever and is supported in the region of its eccentric on the one hand on the bridge and the other on the back of the caliper, usually at the bridge a Wälzrolle is arranged, which acts as a storage for the brake lever. In particular, in order to allow a resulting in the pivoting movement of the brake lever, caused by the eccentricity, resulting tilting of the bridge without this braced in the guideways, one of the guides as fixed and the other is designed as a floating bearing. For this purpose, the loslagerseitige outer radius of the bridge, which is in correspondence with the wall of the caliper, smaller than the radius of curvature of the caliper wall, so that a deflection of the bridge in the operation of the Brake lever, that is possible in an axial displacement in the direction of the brake disc.
Allerdings ergeben sich mit fortschreitender Betriebsdauer insofern Probleme als es zu Abnutzungen kommen kann, die sich nachteilig auf die Standzeit auswirken. However, as the operating life progresses, there are problems in that wear can occur which adversely affects service life.
Darüber hinaus ist eine Winkelbeweglichkeit eines an den Stellspindeln angreifenden Nachstellers sowie eines mit zumindest einer Stellspindel in Eingriff stehenden Mitnehmers als Komponente des Nachstellers erforderlich, was sowohl fertigungstechnische wie auch funktionale Nachteile mit sich bringt. In addition, an angular mobility of an adjuster acting on the adjusting spindles as well as a driver engaging with at least one adjusting spindle is required as a component of the adjuster, which entails both production-related and functional disadvantages.
Der Erfindung liegt die Aufgabe zugrunde, eine Scheibenbremse der gattungsgemäßen Art so weiterzuentwickeln, dass ihre Standzeit erhöht und ihre Funk- tionssicherheit verbessert wird. The invention has for its object to further develop a disc brake of the generic type so that their life increases and their functional safety is improved.
Diese Aufgabe wird durch eine Scheibenbremse mit den Merkmalen des Anspruchs 1 gelöst. Durch die Erfindung ist eine Scheibenbremse geschaffen, bei der die Brücke bei Betätigung des Bremshebels, also bei einer Bremsung, kontrolliert geführt wird, mit der Folge, dass der Anpressvorgang der Bremsbeläge auf die Bremsscheibe sozusagen gesteuert erfolgt. Damit kann ein Ausgleich des bisher auftretenden und an sich bekannten Schrägverschleißes der Bremsbeläge erfol- gen. This object is achieved by a disc brake with the features of claim 1. By the invention, a disc brake is provided, in which the bridge is guided controlled upon actuation of the brake lever, ie during braking, with the result that the Anpressvorgang the brake pads is done so to speak controlled on the brake disc. This can compensate for the hitherto occurring and per se known oblique wear of the brake pads.
Da die Brücke nun definiert geführt ist, reduziert sich der Verschleiß im Bereich der Führung, gegenüber der, wie sie aus dem Stand der Technik bekannt ist, wobei der erfindungsgemäß vorgesehene Führungszapfen als angeformter Zy- linder mit einer geringen Auflagefläche an der Führungsbahn des Bremssattels anliegt, woraus sich überdies eine leichte, d.h. reibwertminimierte Verschiebung der Brücke ergibt. Since the bridge is now guided in a defined manner, the wear in the region of the guide is reduced compared with that known from the prior art, wherein the guide pin provided according to the invention rests against the guideway of the caliper as an integrally formed cylinder with a small bearing surface , from which, moreover, a slight, ie friction-minimized displacement of the bridge results.
Nach einem weiteren Gedanken der Erfindung ist die Führungsbahn, die als Führungsnut ausgebildet sein kann, mit einer Breite, die nur geringfügig größer ist als das zugeordnete Abmaß des Führungszapfens, in einem kurvenförmigen Verlauf vorgesehen, wobei dieser Verlauf, quasi als Kulissenbahn, der durch den Exzenter vorgegebenen axialen und Kippbewegung entspricht, so dass das bislang zu beklagende Kippen der Brücke ausgeglichen wird. Ein notwendiges Toleranzspiel kann zwischen der Brücke und dem Bremssattel durch die Aufteilung des Verlaufs der Führungsbahn auf die Höhen- und Querrichtung reduziert werden. According to a further aspect of the invention, the guide track, which may be formed as a guide, with a width which is only slightly larger than the associated dimension of the guide pin, provided in a curved course, this course, as a kind of slide track, by the Eccentric predetermined axial and tilting movement corresponds, so that the hitherto complained of tilting the bridge is compensated. A necessary tolerance play can be reduced between the bridge and the caliper by dividing the course of the guideway in the vertical and transverse directions.
Da sowohl der Bremssattel wie auch die Brücke als Gussteile hergestellt sind, ist die Realisierung der Erfindung kostenneutral, vor allem weil die Führungselemente mit ein- bzw. angegossen werden können. Since both the caliper and the bridge are made as castings, the realization of the invention is cost-neutral, especially because the guide elements can be cast with or.
Eine kostengünstigere Herstellung, aber auch eine Verbesserung der Funktionssicherheit ergibt sich daraus, dass es durch die Erfindung möglich ist, den Nachsteller und den Mitnehmer starr auszuführen, also ohne die zum Stand der Technik beschriebene Winkelbeweglichkeit beider Bauteile. A more cost-effective production, but also an improvement in the functional safety results from the fact that it is possible by the invention, rigidly perform the adjuster and the driver, ie without the angular mobility of both components described in the prior art.
Bei der bereits erwähnten linearen Ausrichtung der Führungsbahn ist wie bisher, ein Kippen der Brücke ebenso wie eine Querbewegung möglich, entsprechend dem durch die Schwenkbewegung des Exzenterhebels vorgegebenen Verlauf. Allerdings kann das notwendige Toleranzspiel im Bereich des Loslagers wesentlich einfacher erreicht werden als dies bislang der Fall war, da lediglich die Führungsbahn, d.h. die Führungsnut und der einliegende Führungszapfen in ihren Abmessungen entsprechend konzipiert sein müssen. In the already mentioned linear alignment of the guideway as before, a tilting of the bridge as well as a transverse movement is possible, according to the predetermined by the pivotal movement of the eccentric lever course. However, the necessary tolerance play in the area of the floating bearing can be achieved much easier than has hitherto been the case, since only the guideway, i. the guide groove and the inboard guide pin must be designed according to their dimensions.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. 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:
Figur 1 einen Teilausschnitt einer erfindungsgemäßen Scheibenbremse 1 shows a partial section of a disc brake according to the invention
Figur 2 einen Teilausschnitt des Bremssattels der Scheibenbremse, gesehen in Richtung des Pfeiles II in Figur 1 . Figure 2 is a partial section of the caliper of the disc brake, seen in the direction of arrow II in Figure 1.
In der Figur 1 ist ein Teil einer Scheibenbremse für ein Nutzfahrzeug dargestellt, mit einem eine nicht gezeigte Bremsscheibe übergreifenden Bremssattel 1 , in dem eine Zuspanneinrichtung mit einer durch einen schwenkbaren, in der Figur lediglich angedeuteten Bremshebel 4 in Richtung der Bremsscheibe verschiebbaren Brücke 2 gelagert ist. FIG. 1 shows a part of a disc brake for a commercial vehicle, with a brake caliper 1 which engages over a brake disc, not shown, in which an application device with a pivotable in the Figure only indicated brake lever 4 in the direction of the brake disc slidable bridge 2 is mounted.
Die Brücke 2 weist zwei parallel und abständig zueinander angeordnete Ge- windebohrungen 3 auf, in denen axial verstellbare, nicht gezeigte Stellspindeln gehalten sind, mit endseitigen Druckstücken, die einen beim Bremsen an die Bremsscheibe pressbaren Bremsbelag kontaktieren. The bridge 2 has two threaded bores 3 which are arranged parallel and at a distance from one another and in which axially adjustable adjusting spindles, not shown, are held, with end-side pressure pieces which contact a brake pad which can be pressed against the brake disc during braking.
An zwei sich gegenüberliegenden Außenseiten der Brücke 2, und zwar etwa im Bereich einer gedachten Querachse, den Gewindebohrungen 3 zugeordnet, ist jeweils ein Führungszapfen 6 angeformt, der in einer als Führungsnut ausgebildeten Führungsbahn 5 des Bremssattels 1 einliegt. On two opposite outer sides of the bridge 2, approximately in the region of an imaginary transverse axis, associated with the threaded bores 3, a respective guide pin 6 is integrally formed, which rests in a guide track 5 of the caliper 1 designed as a guide groove.
Der Durchmesser des jeweiligen Führungszapfens 6, der als Zylinder ange- formt ist, entspricht im Wesentlichen der Breite der Führungsbahn 5 und die Länge des Führungszapfens 6 etwa der Tiefe der Führungsbahn 5. The diameter of the respective guide pin 6, which is shaped as a cylinder, substantially corresponds to the width of the guide track 5 and the length of the guide pin 6 is approximately the depth of the guide track 5.
Die Führungsbahn 5 kann linear verlaufen oder, wie in Figur 2 dargestellt, mit kurvenförmig gestalteten Seitenwänden 7, die allerdings über die gesamte Länge der Führungsbahn 5 einen gleichen Abstand zueinander aufweisen, entsprechend, wie erwähnt, dem Durchmesser des Führungszapfens 6. The guide track 5 may be linear or, as shown in Figure 2, with curved sidewalls 7, however, over the entire length of the guide track 5 have an equal distance from each other, as mentioned, the diameter of the guide pin. 6
Selbstverständlich besteht auch die Möglichkeit der kinematischen Umkehr, d.h., dass der Bremssattel Führungszapfen 6 und die Brücke diese aufneh- mende Führungsbahn 5 aufweist, und zwar jeder Gewindebohrung 3 zugeordnet, so dass die Brücke 2 zweiseitig gelagert ist. Of course, there is also the possibility of kinematic reversal, that is, that the brake caliper guide pin 6 and the bridge has this receiving guideway 5, namely associated with each threaded hole 3, so that the bridge 2 is mounted on two sides.
