Description
Einrichtung zur Auslösung einer Gefahrbremsung nach BOStrab in einem VollbahnfahrzeugDevice for triggering an emergency braking according to BOStrab in a mainline railway vehicle
Die Erfindung betrifft eine Einrichtung zur Auslösung einer Gefahrbremsung nach BOStrab in einem Vollbahnfahrzeug mit zumindest einem Bremszylinder, einer Bremsgeräteeinheit, einem Gleitschutzventil sowie einer Hauptluftbehälterleitung. The invention relates to a device for triggering an emergency braking according to BOStrab in a main line vehicle with at least one brake cylinder, a braking device unit, an anti-skid valve and a main air tank line.
Vollbahnfahrzeuge mit den vorgenannten Merkmalen haben üblicherweise nur die Bremsarten Betriebsbremsen und Schnellbremsen. Bei dem Schnellbremsen kommt es insbesondere darauf an, den sicherheitsrelevanten Vorsignalabstand aus der zulässigen Höchstgeschwindigkeit einzuhalten. Da Vollbahnfahrzeuge neuerdings auch auf Strecken zum Einsatz kommen, bei denen die Vorschriften der BOStrab gelten, müssen zusätzlich die für das Fahren auf Sicht erforderlichen Bremswege gemäß Anlage 2 der BOStrab eingehalten werden. Dabei liegt das hauptsächliche Problem darin, die Bremswege der sogenannten Gefahrbremsung -Tabelle 2 der Anlage 2 der BOStrab einzuhalten. Es ist sinnvoll, dabei Reibwerte zwischen Rad und Schienen von 0,3 nicht zu überschreiten, da anderenfalls der experimentelle Nachweis (Typtest) durch übermäßige Gleitschutzauslösung selbst auf sauberen trockenen Schienen behindert wird. Weil bei Einleitung einer Bremsung zunächst der erforderliche Druck durch die Bremsgeräteeinheit aufgebaut werden muß und dann immer erst sämtliche Rohrleitungen bis zum Bremszylinder mit Luft gefüllt werden müssen, entstehen für Gefahrbremsungen unakzeptabel lange Zeiten für den Aufbau der Bremskraft.Mainline vehicles with the above-mentioned features usually only have service brakes and emergency brakes. When braking, it is particularly important to maintain the safety-relevant distance from the advance signal from the maximum permissible speed. Since mainline vehicles are now also being used on routes where the BOStrab regulations apply, the braking distances required for driving within sight must also be observed in accordance with Annex 2 of the BOStrab. The main problem here is to observe the braking distances for so-called emergency braking - Table 2 of Annex 2 of the BOStrab. It is advisable not to exceed the friction coefficient between wheel and rail of 0.3, as otherwise the experimental proof (type test) will be hampered by excessive anti-skid activation even on clean, dry rails. Because when braking is initiated, the required pressure must first be built up by the brake device unit and then all the pipes up to the brake cylinder must be filled with air, unacceptably long times arise for the build-up of braking force for emergency braking.
Der Erfindung liegt die Aufgabe zugrunde, ein Vollbahnfahrzeug für einen Einsatz auf BOStrab-Strecken bremstechnisch so auszurüsten, daß im Hinblick auf Gefahrbremsungen die maximale Bremskraft wesentlich schneller erzeugt wird.The invention is based on the object of equipping a mainline railway vehicle for use on BOStrab lines in such a way that the maximum braking force is generated much more quickly with regard to emergency braking.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß für das schnellere Erreichen des maximalen Druckes im Bremszylinder eine zusätzliche Druckerzeugungseinrichtung vorgesehen ist, die im wesentlichen aus einem Vorratsluftbehälter und einem Magnetventil besteht.This object is achieved according to the invention in that an additional pressure generating device is provided for faster reaching of the maximum pressure in the brake cylinder, which essentially consists of a supply air tank and a solenoid valve.
Im weiteren wird die Erfindung anhand eines Ausführungsbeispiels näher beschrieben, das in der Zeichnung schematisch dargestellt ist.The invention is described in more detail below using an embodiment which is shown schematically in the drawing.
Bei Betriebsbremsungen und bei Schnellbremsungen erfolgt die Beaufschlagung des gezeigten Bremszylinders 1 - und ggf. weiterer Bremszylinder, zu denen die verkürzt gezeichnete Rohrleitung 10 führt - von einer Bremsgeräteeinheit 8 über ein Gleitschutzventil 2. Unmittelbar vor dem Gleitschutzventil 2 befindet sich eine zusätzliche Druckerzeugungseinrichtung, über die bei Anforderung der Gefahrbremsung durch den Fahrer der maximale Druck auf den Bremszylinder 1 gegeben wird.During service braking and emergency braking, the brake cylinder 1 shown - and possibly other brake cylinders to which the shortened pipe 10 leads - is pressurized by a braking device unit 8 via an anti-skid valve 2. Immediately in front of the anti-skid valve 2 there is an additional pressure generating device, via which the maximum pressure is applied to the brake cylinder 1 when the driver requests emergency braking.
Die Druckerzeugungseinrichtung ist über ein Rückschlagventil 3 mit der Hauptluftbehälterleitung 9 verbunden. Ein Druckminderventil 4 reduziert den in der Hauptluftbehälterleitung 9 bestehenden Druck auf den erforderlichen maximalen Bremszylinderdruck für die Gefahrbremsung. Bei Einleitung der Gefahrbremsung durch den Fahrer wird ein Magnetventil 6 geöffnet. Ein Vorratsluftbehälter 5 dient zur Speicherung eines genügend großen Luftvolumens in möglichst großer Nähe zu dem Bremszylinder 1. Über ein Rückschlagventil 7 wird verhindert, daß die Luftleitung zur Bremsgeräteeinheit 8 ebenfalls mitThe pressure generating device is connected to the main air tank line 9 via a non-return valve 3. A pressure reducing valve 4 reduces the pressure in the main air tank line 9 to the required maximum brake cylinder pressure for emergency braking. When the driver initiates emergency braking, a solenoid valve 6 is opened. A supply air tank 5 is used to store a sufficiently large volume of air as close as possible to the brake cylinder 1. A non-return valve 7 prevents the air line to the brake device unit 8 from also being filled with

Ein Nachrüsten vorhandener Fahrzeuge mit der zusätzlichen Druckerzeugungseinrichtung ist ohne weiteres möglich.Retrofitting existing vehicles with the additional pressure generating device is easily possible.
