Description
Vorrichtung zur Parallelführung der Belaghalter von Teilbelag-ScheibenbremsenDevice for parallel guidance of the pad holders of partial pad disc brakes
Die Erfindung betrifft eine Vorrichtung zur Parallelführung der Belaghalter von Teilbelag-Scheibenbremsen, insbesondere an Schienenfahrzeugen, wobei die Belaghalter drehbeweglich an Bremshebeln befestigt sind und die Bremshebel zusammen mit einer am Drehgesteil oderWagenkasten angeordneten Bremsbrücke und einem Bremszylinder eine Bremszange bilden.The invention relates to a device for parallel guidance of the pad holders of partial pad disc brakes, in particular on rail vehicles, wherein the pad holders are rotatably attached to brake levers and the brake levers together with a brake bridge arranged on the bogie or car body and a brake cylinder form a brake caliper.
Zur Parallelführung und zum gleichzeitigen Abfangen der Tangentialkräfte der Belaghalter dienen üblicherweise am Drehgestell oder Wagenkasten befestigte Hängelaschen (vgl. DE 42 06 342 C2). Die Parallelführung des Beiaghalters parallel zur Bremsscheibenoberfläche geschieht dabei durch zwei parallele Drehachsen der Hängelasche, wobei die Belaghaiter zwar auf die Bremsfläche zu und von dieser wegbewegt werden können aber nicht um eine Drehachse senkrecht zu diesen beiden Drehachsen verdrehbar sind. Bei dieser Aufhängung und Parallelführung des Belaghaiters ist außerdem die mit den Bremshebeln verbundene Bremsbrücke mit einem Aufhängepunkt, normalerweise in Form eines Elastomerlagers, am Drehgesteil oder Wagenkasten um eine Drehachse drehbeweglich angeordnet, die parallel zur Achse der Bremsscheibe angeordnet ist.Hanging brackets attached to the bogie or car body are usually used to guide the pad holders in parallel and to simultaneously absorb the tangential forces. The parallel guidance of the pad holder parallel to the brake disc surface is achieved by two parallel axes of rotation of the hanging bracket, whereby the pad holders can be moved towards and away from the braking surface but cannot be rotated about an axis of rotation perpendicular to these two axes of rotation. With this suspension and parallel guidance of the pad holder, the brake bridge connected to the brake levers is also arranged on the bogie or car body with a suspension point, normally in the form of an elastomer bearing, so that it can rotate about an axis of rotation that is arranged parallel to the axis of the brake disc.
Bei bestimmten kompakt gebauten Bremsen wird die Bremskraft (Tangentialkraft) nicht durch die erwähnten Hängelaschen aufgenommen, sondern durch die Bremshebel auf die Brücke übertragen. Diese Brücke benötigt dann zur Abstützung des Bremsmomentes zwei Befestigungspunkte am Drehgestell oderWagenkasten. Eine Parallelführung der Belaghalter muß bei Wegfall der Hängeiaschen in anderer Weise durchgeführt werden.In certain compact brakes, the braking force (tangential force) is not absorbed by the above-mentioned hanging brackets, but is transferred to the bridge by the brake levers. This bridge then requires two fastening points on the bogie or car body to support the braking torque. If the hanging brackets are omitted, the pad holders must be guided parallel in another way.
Der Erfindung liegt daher die Aufgabe zugrunde, durch geeignete und kostengünstige Maßnahmen eine Parallelführung der Bremsbeläge gegenüber der Bremsscheibe sicherzustellen.The invention is therefore based on the object of ensuring parallel guidance of the brake pads relative to the brake disc by means of suitable and cost-effective measures.

Die Lösung dieser Aufgabe ist im Kennzeichen des Anspruches angegeben. Danach wird ein Paralleihebel etwa mittig drehbar am Bremshebel befestigt, wobei seine Drehachse parallel zu den Drehachsen des Beiaghaiters bzw. des Bremshebeis angeordnet ist und die Enden des Paraileihebels in Aussparungen ähnlich der Zahnlücken von Zahnrädern sowohl des Belaghalters als auch der Bremsbrücke drehbeweglich eingreifen. Der Parallelhebel greift also wie ein "Zahnrad mit zwei Zähnen" in je eine "Zahnlücke" von Belaghalter und Bremsbrücke ein. Beim Schwenken des Bremshebels um die an der Bremsbrücke angeordnete Drehachse verdreht sich bei dieser erfindungsgemäßen Anordnung der Parallelhebe! in entsprechender Weise in gleicher Drehrichtung, jedoch um etwa den doppelten Winkel, und führt so den Belaghalter genau um den Schwenkwinkel des Bremshebels zurück, hält diesen also parallel zur Bremsfläche der Bremsscheibe.The solution to this problem is specified in the characterizing part of the claim. Accordingly, a parallel lever is attached to the brake lever in a manner that it can rotate approximately in the middle, with its axis of rotation being arranged parallel to the axis of rotation of the brake lever and the brake lever, and the ends of the parallel lever engaging in recesses similar to the tooth gaps of gears of both the pad holder and the brake bridge. The parallel lever thus engages in a "tooth gap" of the pad holder and brake bridge like a "gear with two teeth". When the brake lever is pivoted about the axis of rotation arranged on the brake bridge, the parallel lever rotates in the same direction of rotation in this arrangement according to the invention, but by approximately twice the angle, and thus guides the pad holder back by exactly the pivot angle of the brake lever, thus holding it parallel to the braking surface of the brake disc.
Die Erfindung wird anhand der beigefügten Figuren 1 a und b sowie 2 a und c beispielsweise näher erläutert.The invention is explained in more detail using the attached figures 1 a and b and 2 a and c for example.
In den Figuren 1 a und 1 b ist der Stand der Technik mit einer Parallelführung durch Hängelasche beschrieben. Fig. 1 a zeigt eine Seitenansicht und Fig. 1 b eine Draufsicht.Figures 1 a and 1 b describe the state of the art with parallel guidance using a hanging bracket. Figure 1 a shows a side view and Figure 1 b a top view.
In den Figuren 2 a bis12 c ist die erfindungsgemäße Konstruktion ebenfalls in der Seitenansicht (Fig. 2 a) und in der Draufsicht (Fig. 2 b + c) dargestellt.In Figures 2a to 12c , the construction according to the invention is also shown in side view (Fig. 2a) and in plan view (Fig. 2b + c).
In den Figuren wirken auf die Bremsscheibe 1 von beiden Seiten die Beläge 6, die an Beiaghaltem 2 befestigt sind und über die Drehachsen 7 an den Bremshebein 4 befestigt sind. Die Bremshebel 4 sind um die Drehachsen 8 drehbar und besitzen an ihrem den Beiaghaltem 2 gegenüberliegenden Ende die Drehachsen 9, an denen der Bremszylinder 3 angreift.In the figures, the brake disc 1 is acted upon from both sides by the pads 6, which are attached to the side brackets 2 and are attached to the brake levers 4 via the rotation axes 7. The brake levers 4 can be rotated about the rotation axes 8 and have the rotation axes 9 at their end opposite the side brackets 2, on which the brake cylinder 3 engages.
Nach dem in Fig. 1 a und b dargestellten Stand der Technik wird die Tangentialkraft des Belaghalters über am Drehgestell 10 oder Fahrzeugrahmen befestigte Hängelaschen 11 aufgefangen, wobei die Hängelasche zwei parallel zueinander angeordnete Drehachsen 12 und 13 besitzt. Die Bremsbrücke 5 ist nach dem Stand der Technik über den Aufhängepunkt 14 ebenfalls am Drehgestell 10 gelagert.According to the state of the art shown in Fig. 1 a and b, the tangential force of the pad holder is absorbed by hanging brackets 11 attached to the bogie 10 or the vehicle frame, whereby the hanging bracket has two axes of rotation 12 and 13 arranged parallel to one another. According to the state of the art, the brake bridge 5 is also mounted on the bogie 10 via the suspension point 14.

Bei der erfindungsgemäßen Konstruktion nach den Figuren 2 a bis c wird auf die Hängeiaschen 11 verzichtet. Die Bremsbrücke ist statt dessen über zwei Aufhängepunkte 14a und 14b fest mit dem Drehgestell 10 verbunden. Zur Parallelführung dient statt dessen der Parallelhebel 15 mit der zentralen parallel zu den Drehachsen 7, 8 und 9 angeordneten Drehachse 16. Die beiden Enden 17 des Paraiielhebels 15 greifen einerseits in eine Aussparung 18 des Belaghalters 2 und andererseits in eine Aussparung 19 der Bremsbrücke 5 ein. Bei einer Betätigung des Bremszylinders 3 kommt es hierbei zu einer Drehbewegung des Bremshebels 4 um die Drehachse 8 und einer gleichsinnigen Drehung des Parallelhebels 15 um die Drehachse 16, jedoch mit etwa dem doppelten Winke!, so daß die Belaghalter 2 mit ihren Belägen 6 immer parallel zu den Bremsflächen der Bremsscheibe eingestellt werden.In the construction according to the invention according to Figures 2 a to c, the hanging brackets 11 are dispensed with. Instead, the brake bridge is firmly connected to the bogie 10 via two suspension points 14a and 14b. Instead, the parallel lever 15 with the central axis of rotation 16 arranged parallel to the axes of rotation 7, 8 and 9 serves for parallel guidance. The two ends 17 of the parallel lever 15 engage on the one hand in a recess 18 of the pad holder 2 and on the other hand in a recess 19 of the brake bridge 5. When the brake cylinder 3 is actuated, the brake lever 4 rotates about the axis of rotation 8 and the parallel lever 15 rotates in the same direction about the axis of rotation 16, but at approximately twice the angle!, so that the pad holders 2 with their pads 6 are always set parallel to the braking surfaces of the brake disc.
