Abstract

In an undercarriage for railway vehicles, the brake body (3) of a magnetic rail brake or of an eddy-current brake is held by means of a drive device (4) so as to be capable of being lowered or raised between an upper position of rest and a lower operative position and supported in both positions by stops (6 and 1e, respectively). In order to keep the constructional outlay as small as possible and to achieve a moment-free force flow, the drive device (4) is secured to a carrier (1) of the undercarriage frame which does not carry out any resilient movements with respect to the rail (7) so that there is a spacing between carrier (1) and rail (7) which is to this extent constant. In addition, the aforesaid carrier (1) has the stops (1e) which support the brake body (3) in its operative position and are provided in order to avoid moments in the direction of action of the forces occurring. <IMAGE>

Description

Die Erfindung betrifft ein Fahrwerk für Schienenfahrzeuge mit einer Magnetschienenbremse oder einer Wirbelstrombremse, deren Bremskörper mittels einer an einem Träger des Fahr­werkrahmens befestigten Antriebsvorrichtung zwischen einer oberen Ruhestellung und einer unteren Wirkstellung senk­bzw, hebbar gehalten und in beiden Stellungen über Anschlä­ge abgestützt ist.The invention relates to a chassis for rail vehicles with a magnetic rail brake or an eddy current brake, the braking body of which is lowered or raised by means of a drive device fastened to a carrier of the chassis frame between an upper rest position and a lower active position and supported in both positions by stops.

Bei Drehgestellen von Schienenfahrzeugen ist es üblich, den Bremskörper an einem Rahmenträger aufzuhängen, der gegen­über den Radlagern abgefedert ist und somit einen variablen Abstand zur Schiene hin aufweist. Ein zusätzlicher, an den Radlagern jeder Längsseite ungefedert angeschlossener Träger dient dem Anordnen von Anschlägen, die den in Wirkstellung befindlichen Bremskörper in Längs- und Querrichtung und bei der Wirbelstrombremse zudem in vertikaler Richtung abstützen. Da die beim Bremsen auftretenden Kräfte in Ebene der Schiene wirken und der zusätzliche Träger lagerseitig, also außer­halb der Schienenebene gehalten ist, treten beträchtliche Momente auf. Zum Aufnehmen dieser Momente werden die zu­sätzlichen Träger durch Querstreben miteinander verbunden.In the case of bogies of rail vehicles, it is customary to hang the brake body on a frame support which is cushioned against the wheel bearings and thus has a variable distance from the rail. An additional, unsprung support connected to the wheel bearings on each long side is used to arrange stops that support the active brake body in the longitudinal and transverse directions and, in the case of the eddy current brake, also in the vertical direction. Since the forces occurring during braking act in the plane of the rail and the additional carrier is held on the bearing side, that is to say outside the rail plane, considerable moments occur. To absorb these moments, the additional beams are connected to one another by cross struts.

Der Erfindung liegt die Aufgabe zugrunde, ein Fahrwerk der gattungsgemäßen Art so auszugestalten, daß der zuvor erläuterte bauliche Aufwand vermieden und ein weitaus besserer, momentenfreier Kraftfluß erreicht werden.The invention has for its object to design a chassis of the generic type so that the previously described construction costs are avoided and a much better, torque-free power flow can be achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der die Antriebsvorrichtung haltende Träger des Fahrwerk­rahmens keine federnden Bewegungen in bezug auf die Schiene ausführt, so daß ein insoweit gleichbleibender Abstand zwischen Träger und Schiene besteht und daß die­ser Träger auch die den Bremskörper in dessen Wirkstellung abstützenden Anschläge aufweist, die zum Vermeiden von Momenten in Wirkrichtung der auftretenden Kräfte angeord­net sind.This object is achieved in that the drive device holding the carrier of the chassis frame does not perform any resilient movements with respect to the rail, so that there is a constant distance between the carrier and the rail and that this carrier also has the stops supporting the brake body in its operative position , which are arranged to avoid moments in the direction of action of the forces occurring.

Die mit der Erfindung erzielbaren Vorteile ergeben sich aus Aufgabe und Lösung unmittelbar. Ergänzend bleibt zu erwäh­nen, dat durch den jetzigen Wegfall der bislang üblichen Querstreben eine Verwindungsfähigkeit des Fahrwerkrahmens nicht mehr behindert wird.The advantages that can be achieved with the invention result directly from the problem and the solution. In addition, it should be mentioned that the torsion of the chassis frame is no longer hampered by the current elimination of the previously common cross struts.

Auf die den Unteransprüchen entnehmbaren Ausgestaltungen des Erfindungsgedankens wird im folgenden Teil der Be­schreibung näher eingegangen.The embodiments of the inventive concept which can be gathered from the subclaims are discussed in more detail in the following part of the description.

Das gezeigte Fahrwerk hat einen Rahmen, der aus zwei Längs­trägern 1 und daran angebrachten Auslegern 1a besteht. Die Ausleger 1a sind jeweils mit dem gegenüberliegenden Längs­träger 1 gelenkig verbunden. An den gabelförmig ausgebilde­ten Enden 1b der Längsträger 1 befinden sich Lagerungen 1c für Wellenstücke 2a von Rädern 2. Eine bei Fahrwerken oder Drehgestellen an sich übliche Abfederung des Rahmens auf den Radlagerungen ist hier nicht vorhanden und wegen der relativ geringen Masse des Rahmens auch nicht erforderlich.The chassis shown has a frame which consists of two longitudinal beams 1 and brackets 1a attached to them. The brackets 1a are each articulated to the opposite side member 1. At the fork-shaped ends 1b of the side members 1 there are bearings 1c for shaft pieces 2a of wheels 2. A suspension of the frame on the wheel bearings, which is inherently common in running gear or bogies, is not present here and is not necessary because of the relatively small mass of the frame.

Unterhalb jedes Längsträgers 1 ist ein Bremskörper 3 einer Magnetschienenbremse oder einer Wirbelstrombremse angeordnet. Der Bremskörper 3 ist mittels einer Antriebsvorrichtung 4 - beispielsweise durch zwei druckluftbetätigte und feder­vorgespannte Zylinder - zwischen einer oberen Ruhestellung und einer unteren Wirkstellung verstellbar. Gemäß Fig. 1 A und Fig. 2 A sind die an Konsolen 1d des Längsträgers 1 ge­haltenen Zylinder der Antriebsvorrichtung 4 diagonal gegen­ überliegend angeordnet. Bei dem Ausführungsbeispiel nach Fig. 1 B und 2 B befinden sich die Zylinder der Antriebs­vorrichtung 4 in Längsachse des Längsträgers 1.A brake body 3 of a magnetic rail brake or an eddy current brake is arranged below each side member 1. The brake body 3 can be adjusted between an upper rest position and a lower operative position by means of a drive device 4 - for example by means of two compressed air-actuated and spring-loaded cylinders. According to FIG. 1A and FIG. 2A, the cylinders of the drive device 4 held on brackets 1d of the longitudinal beam 1 are diagonally opposite arranged above. In the exemplary embodiment according to FIGS. 1 B and 2 B, the cylinders of the drive device 4 are located in the longitudinal axis of the side member 1.

Jeder Bremskörper 3 ist in seiner oberen Ruhestellung durch die Federvorspannkraft der Antriebsvorrichtung 4 gehalten, durch zwei (Fig. 1 A und 2 A) oder vier (Fig. 1 B und 2 B) Federelemente 5 (siehe Fig. 5, obere Bildhälfte) gegenüber dem jeweiligen Längsträger 1 vertikal abgefedert und durch eine Anschlagvorrichtung 6 (siehe Fig. 5, untere Bildhälfte) in der Horizontalebene fixiert.Each brake body 3 is held in its upper rest position by the spring biasing force of the drive device 4, by two (FIGS. 1A and 2 A) or four (FIGS. 1 B and 2 B) spring elements 5 (see FIG. 5, upper half of the figure) opposite the respective side member 1 vertically cushioned and fixed in the horizontal plane by a stop device 6 (see FIG. 5, lower half of the figure).

Die Federelemente 5 sind über Schrauben 5a mit den Längs­trägern 1 und mit einem Oberteil 6a der entsprechend DE-PS 24 15 858 gestalteten Anschlagvorrichtung 6 verbunden. Dieses Oberteil 6a wirkt mit einem am Bremskörper 3 befestig­ten Zentrierkegel 6b zusammen, der im übrigen mittels einer Exzenterbuchse 6c paßgenau eingestellt werden kann.The spring elements 5 are connected by screws 5a to the side members 1 and to an upper part 6a of the stop device 6 designed in accordance with DE-PS 24 15 858. This upper part 6a interacts with a centering cone 6b fastened to the brake body 3, which can be adjusted precisely by means of an eccentric bushing 6c.

In der unteren Wirkstellung liegt der Bremskörper 3 der Magnetschienenbremse direkt auf der Schiene 7, wogegen zwischen dem Bremskörper 3 der Wirbelstrombremse und der Schiene 7 ein definierter Luftspalt bestehen muß. Um die beim Bremsen auftretenden Reaktionskräfte momentenfrei aufzunehmen, weist der Längsträger 1 in Wirkrichtung dieser Kräfte angeordnete Anschläge le auf. Diese Anschläge 1e können bei der Magnetschienenbremse als einfache Längsan­schläge (siehe Fig. 2 A) ausgebildet sein.In the lower active position, the brake body 3 of the magnetic rail brake lies directly on the rail 7, whereas a defined air gap must exist between the brake body 3 of the eddy current brake and the rail 7. In order to absorb the reaction forces occurring during braking without torque, the side member 1 has stops le arranged in the effective direction of these forces. These stops 1e can be designed as simple longitudinal stops (see FIG. 2A) in the magnetic rail brake.

Im Fall der Wirbelstrombremse sind die Anschläge 1e (siehe Fig. 3 und 4) neben ihrer Funktion in Längsrichtung auch vertikal nach unten hin sowie in Querrichtung wirksam. Dazu hat der jeweilige Anschlag le eine Aufnahme 1f für einen Nocken 3b an einem Kragarm 3a des Bremskörpers 3. Wie aus Fig. 4 ersichtlich, ist die Aufnahme lf in ihrer Höhe ein­stellbar (Langloch für Klemmschrauben, gezahnte Kontakt­ flächen) mit dem Anschlag 1e verbunden, Dadurch kann der gewollte Luftspalt zwischen Bremskörper 3 und Schiene 7 auf einfache Weise bei der Erstmontage eingestellt bzw. bei Verschleiß an den Rädern 2 nachgestellt werden. Die Fixierung des abgesenkten Bremskörpers 3 in Querrichtung erfolgt über die Seitenflächen der Aufnahme 1f und des Nockens 3b. Diese Seitenflächen sind prismatisch gestaltet, um beim Absenken des Bremskörpers 3 ein leichtes Einfädeln des Nockens 3b in die Aufnahme 1f zu ermöglichen.In the case of the eddy current brake, the stops 1e (see FIGS. 3 and 4) are effective in addition to their function in the longitudinal direction, vertically downward and in the transverse direction. For this purpose, the respective stop le has a receptacle 1f for a cam 3b on a cantilever arm 3a of the brake body 3. As can be seen from FIG. 4, the height of the receptacle lf is adjustable (elongated hole for clamping screws, toothed contact surfaces) connected to the stop 1e, this allows the desired air gap between the brake body 3 and the rail 7 to be easily adjusted during initial assembly or readjusted when the wheels 2 are worn. The lowered brake body 3 is fixed in the transverse direction via the side surfaces of the receptacle 1f and the cam 3b. These side surfaces are designed prismatic in order to enable the cam 3b to be easily threaded into the receptacle 1f when the brake body 3 is lowered.
