Vorliegende Erfindung betrifft eine Vorrichtung, die in erster Linie dazu dienen soll. bei Gleisfahrzeugen, einschließlich Lokomotiven und elektrischen Motorwagen, das Fahrzeug bzw. den Zug zum Stehen zu bringen, wenn alle anderen Bremsen versagen.The present invention relates to a device which is primarily intended to serve this purpose. for rail vehicles, including locomotives and electric motor vehicles, the vehicle or to bring the train to a stop if all other brakes fail.

Weiter sol! sie dazu dienen, in gleichzeitiger Wirkung mit den vorhandenen Notbremsen ein rascheres Halten des Fahrzeuges bzw.' ίο Zuges zu veranlassen.Go on sol! they serve in simultaneous action with the existing emergency brakes faster stopping of the vehicle or ' ίο train.

Bei den bekannten Einrichtungen dieser Art • ist die Sicherheit in der Wirkung zum mindesten eine höchst unvollkommene. Die vollkommene Wirkungssicherheit ist aber das Haupterfordernis, dem eine \⁷'orrichtung genügen muß, welche, wie der Gegenstand vorliegender Erfindung, gerade dann in Tätigkeit treten soll, wenn alle anderen Bremsen versagen. Demgemäß ist es die der vorao liegenden Erfindung zugrunde liegende Aufgabe, diese vollkommene Sicherheit in der Wirkung durch eine neuartige Konstruktion der Vorrichtung zu erzielen.In the case of the known devices of this type, the safety in effect is at least a highly imperfect one. However, the perfect reliability of action is the primary requirement, the 'must satisfy orrichtung a \ ^7, which, as the subject of the present invention, just then to come into operation when all other brakes fail. Accordingly, the object on which the invention is based is to achieve this complete safety in the effect by means of a novel construction of the device.

B. unter dem elektrischen Motorwagen, vor den Rädern senkrecht über jeder Gleisschiene angebracht wird, ist die Führungsstange b senkrecht verschiebbar gelagert. Diese trägt am oberen Ende das Gewicht c und am anderen Ende seitlich, parallel zur Gleisschiene, je eine Aufhängeschiene d, die mit je zwei Aussparungen c versehen ist. Die Tiefe der Aussparungen c ist so bemessen, wie sich aus dem Weiter unten Geschilderten ergibt. Die Führungsstange b besitzt außerdem einen Anschlagring f. In dem Führungsbock A ist ferner wagerecht verschiebbar der Bolzen g gelagert, der im Zu-Fig. Ι the device in side view,

B. is mounted under the electric motor car, in front of the wheels vertically above each track rail, the guide rod b is mounted vertically displaceable. This carries the weight c at the upper end and at the other end laterally, parallel to the track rail, a suspension rail d each, which is provided with two recesses c . The depth of the recesses c is dimensioned as follows from what is described below. The guide rod b also has a stop ring f. In the guide block A , the bolt g is also mounted so that it can be moved horizontally, which is

Durch ein Gestänge ο. dgl. ist. der Bolzen g mit einem auf dem Führerstande des Wagens angeordneten Hebel verbunden, in der Weise, daß durch Drücken dieses Hebels der Bolzen g angezogen wird, wodurch die Führungsstange b freigegeben wird und nach unten gleiten kann. An der Führungsslange /■· lose aufgehängt ist der Bremsschuh B. Dieser besteht aus der Zunge i und dem Kopf k. An letzterem sind an den Längsseiten je zwei Bügel I angebracht. Mit diesen ist der Bremsschuh B lose in den Aussparungen c der Schienen d aufgehängt, so daß er in der durch die Feststellvorrichtung g, 0, Ii gewährleisteten Ruhelage über der Gleisschiene und parallel zu dieser schwebt. Die Lage der Bügel / in den Aussparungen c wird durch Ringe .·>' (in Fig. 1 nicht eingezeichnet) gesichert.in connection with the detent h in the guide rod b and the spring 0 is used as a lock, which holds the guide rod b in its rest position. Through a linkage ο. like. is. the bolt g is connected to a lever arranged on the driver's cab of the car, in such a way that, by pressing this lever, the bolt g is tightened, whereby the guide rod b is released and can slide downwards. The brake shoe B is loosely suspended from the guide length / ■ · This consists of the tongue i and the head k. Two brackets I are attached to the long sides of the latter. With these, the brake shoe B is loosely suspended in the recesses c of the rails d , so that in the rest position ensured by the locking device g, 0, Ii it floats above the track rail and parallel to it. The position of the bracket / in the recesses c is secured by rings. ·>'(Not shown in FIG. 1).

Für Verwendung auf Rilleu<chienen ist der Bremsschuh B folgendermaßen ausgebildet. Der Kopf k des Bremsschuhs besitzt die ganze Breite der Gleitschiene, während die Zunge i nur die Breite der Lauffläche ier Schiene hat. Um das Anstoßen .lcs Spurkran/es des RadesFor use on grooved rails, the brake shoe B is designed as follows. The head k of the brake shoe has the entire width of the slide rail, while the tongue i only has the width of the running surface ier rail. To bump .lcs wheel crane / es of the wheel

Claims

to avoid during its rolling up on the brake shoe, i.-t au the head A 'of the brake shoe B, a recess p arranged on the Unterrläche of the head /,. are also two guide pieces m that during lowering of the brake shoe in the groove of the track Schiens intervene. "

l'for use on ordinary track rails instead of the guide pieces; //, the brake shoe has two guide strips that are ije when lowering the brake shoe sideways place the rail head against each other.

The operation of the device is he following: If the brake device come into operation, the lever connected to the Bolzeng "is herimgelegt the driver's cab a result, the rod is released b and slides down the brake shoe B lies down on to the track rail, inter.. engagement of the guide pieces m in the Lille thereof (for grooved rails) or ordinary under Jmfassung of the rail head by the JETR. Führnugsleislen C at rails). in order to always effective to cause the braking required position of the brake shoe on the rail, the depth of the Recesses c are dimensioned so that the loosening of the shoe from its suspension does not take place at the moment the brake shoe is placed on the rail. Rather, the depth of the recesses c is dimensioned so that the brake shoe is initially perforated after it has been placed on the rail the bracket / is taken along by the suspension rails d in the direction of travel of the vehicle. As a result, the brake shoe grinds a certain distance on the rail. Meanwhile, the guide rod b slides under the action of the weight e i-pus down and finally releases the 5 lugs / out of the recesses e and thus len brake shoe completely free. This now remains on the rail, completely detached from the vehicle and, as a result of the previous dragging on the rail, in the correct, effective position, while the vehicle continues to roll until the wheel in question hits the brake shoe Vehicle comes to a standstill.

After Gehrauch the guide rod is b on hand pressed upwards again until the ^r erriegelung g, o, the rod h b holds. ) The brake shoe is hung up in the recesses c by means of the burl / so that the device is ready for use again.

Due to the novel arrangement described and the mode of operation caused by it is therefore the one that is completely free from the vehicle and required for braking correct position of the brake shoe on the track, so that with .this Device in contrast to the known devices a complete security in the effect is achieved.
