Abstract

Functional components (14) such as the steering mechanism, transformer, engine, gearing, fuel tank and running gear are mounted on the main chassis frame (1) in such a way that in the event of a collision, these components can move in relation to the main chassis frame and superstructure. The functional components are mounted on shock absorber fittings (18-21, 26-29) consisting of springs and damping elements, which in turn are secured to buffers (14-17, 26-29) fixed to the main chassis frame and locomotive superstructure.

Description

Die Erfindung bezieht sich auf ein Schienenfahrzeug, insbesondere Lokomotive, mit einem Hauptrahmen und am Hauptrahmen angeordneten Funktionselementen, wie Umrichter, Transformatoren, Motoren, Getriebe, Kraftstoffbehälter, Kühlermodule, Laufwerke und dergleichen.The invention relates to a rail vehicle, in particular Locomotive, with a main frame and arranged on the main frame Functional elements such as converters, transformers, Engines, gearboxes, fuel tanks, cooler modules, drives and the same.

Bei Schienenfahrzeugen dieser Art sind Einrichtungen vorzusehen, mit denen das Fahrzeug oder wichtige Teile hiervon im Falle von außerordentlichen Aufprallbelastungen vor ernsthaften Beschädi-gungen geschützt werden kann. Hierzu ist es beispielsweise aus der DE-PS 196 35 221 bekannt, an den Enden des Hauptrahmens Energieverzehrelemente anzuordnen, die im Falle eines Aufpralls nach ausschöpfen des Federweges der elastischen Pufferelemente Arbeit durch plastische Verformung (Stauchverformung) aufnehmen. Den durch elastische und/oder plastische Verformung gekennzeichneten Methoden zur Arbeitsaufnahme ist die Bindung an einen Verformungsweg gemeinsam.For rail vehicles of this type, facilities must be provided with which the vehicle or important parts thereof in the case of extraordinary impact loads before serious damage can be protected. For this it is off, for example DE-PS 196 35 221 known at the ends of the main frame Arrange energy consumption elements in the event of an impact after exhausting the spring travel of the elastic buffer elements Start work through plastic deformation (compression deformation). The one characterized by elastic and / or plastic deformation Methods of starting work is binding to one Deformation path together.

Da die Möglichkeiten zur Steigerung der Aufprallfestigkeit durch eine Erhöhung der Strukturfestigkeit meist durch Zulassungsvorschriften begrenzt sind, kann das Arbeitsaufnahmevermögen der durch elastische und/oder plastische Verformung wirkenden Energieverzehrelemente nur über eine Verlängerung der Verformungswege gesteigert werden. Dies ist jedoch mit einer aufwendigen und im Schienenverkehr nachteiligen Verlängerung des Gesmatfahrzeugs verbunden.Because the opportunities to increase impact resistance through an increase in structural strength mostly through approval regulations are limited, the capacity of the due to elastic and / or plastic deformation Energy consumption elements only by extending the deformation paths be increased. However, this is expensive and disadvantageous extension of the Gesmat vehicle in rail transport connected.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einem Fahrzeug der genannten Art die Aufprallfestigkeit ohne Verlängerung des Gesamtfahrzeugs zu steigern, wobei die Aufprallfestigkeit bedeutet, daß bei einer außerordentlichen Aufprallbelastung die tragende Struktur und wichtige Teile des Schienenfahrzeugs im wesentlichen unbeschädigt bleiben.The invention is therefore based on the object Vehicle of the type mentioned impact resistance without extension to increase the overall vehicle, the impact resistance means that with an extraordinary impact load the load-bearing structure and important parts of the rail vehicle remain essentially undamaged.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Funktionselemente gegenüber dem Hauptrahmen definiert verschiebbar gelagert sind, wobei nach Überschreitung vorbestimmter, durch eine Aufprallbelastung hervorgerufener Massenkräfte eine Verschiebung der Funktionselemente gegenüber dem Hauptrahmen und tragenden Strukturen des Schienenfahrzeugs unter Arbeitsaufnahme stattfindet.This object is achieved in that the Functional elements can be moved relative to the main frame are stored, whereby after exceeding predetermined, mass forces caused by an impact load Displacement of the functional elements in relation to the main frame and load-bearing structures of the rail vehicle under work takes place.

Nach der Erfindung wird somit erreicht, daß die aus schweren, kompakten Teilmassen bestehenden Funktionselemente des Schienenfahrzeugs, wie z.B. Umrichter, Transformatoren, Laufwerke oder Motoren nicht mehr starr, sondern in Aufprallrichtung unter Energieaufnahme verschieblich in das Schienenfahrzeug integriert werden.According to the invention it is thus achieved that the heavy, compact partial masses of existing functional elements of the rail vehicle, such as. Inverters, transformers, drives or Motors no longer rigid, but under in the direction of impact Energy absorption slidably integrated into the rail vehicle become.

Vorzugsweise werden als Verschiebewege für die Funktionselemente die für deren Montage und Wartung erforderlichen Freiräume oder sonstige Abstandsräume genutzt.Are preferably used as displacement paths for the functional elements the clearances required for their installation and maintenance or other spaces are used.

Die Befestigung an der tragenden Struktur des Fahrzeugs, im wesentlichen dem Hauptrahmen, erfolgt durch bekannte Maschinenelemente, die eine Verschiebung unter Energieaufnahme zulassen. Die Verschiebung kann dabei durch Gleitreibung der Elemente erfolgen mit denen die Funktionselemente am Hauptrahmen oder an sonstigen tragenden Strukturelementen befestigt sind.The attachment to the supporting structure of the vehicle, in essentially the main frame, is made by known machine elements, which allow a shift under energy consumption. The shift can be caused by sliding friction of the elements with which the functional elements on the main frame or on other supporting structural elements are attached.

Die Verschiebung unter Arbeitsaufnahme kann zusätzlich oder anstelle der Gleitreibung auch dadurch erfolgen, daß jeweils zwischen einem strukturfesten Anschlag und dem Funktionselement Energieverzehrelemente angeordnet sind, bei denen die Arbeitsaufnahme mit elastischer und/oder plastischer Verformung einhergeht. Grundsätzlich sind zu diesem Zweck auch übliche mechanisch oder hydraulisch wirkende Stoßdämpferelemente geeignet.The shift in taking up work can additionally or instead of sliding friction also take place in that in each case between a structurally fixed stop and the functional element Energy consumption elements are arranged, in which the start of work is accompanied by elastic and / or plastic deformation. In principle, conventional mechanical ones are also used for this purpose or hydraulically acting shock absorber elements.

Die Erfindung wird nachfolgend anhand einer in der beiliegenden Zeichnung schematisch dargestellten Lokomotive näher erläutert.The invention is described below with reference to the enclosed Drawing schematically illustrated locomotive explained in more detail.

Die Lokomotive besteht aus einem Hauptrahmen 1, an dem zwei Laufwerke in Form von Drehgestellen 2 und 3 über rahmenfeste Drehzapfen 4 und 5 angelenkt sind. In den Drehgestellrahmen 6 und 7 der Drehgestelle 2 und 3 sind jeweils Radsätze 8 gelagert. Die Drehgestelle 2 und 3 sind gegenüber den rahmenfesten Drehzapfen 4 und 5 mittels nicht dargestellter Federlemente elastisch horizontal verschiebbar.The locomotive consists of a main frame 1 on which two Drives in the form of bogies 2 and 3 over fixed frames Pivots 4 and 5 are articulated. In the bogie frame 6 and 7 of the bogies 2 and 3, wheel sets 8 are mounted. The bogies 2 and 3 are opposite the fixed pivots 4 and 5 elastic by means of spring elements, not shown horizontally movable.

Auf der Oberseite des Hauptrahmens 1 ist das Lokomotivgehäuse 9 befestigt, das in dem zwischen den beiden Fahrerständen 10 und 11 befindlichen Bereich aufgebrochen dargestellt ist. In diesem Bereich sind in stark vereinfachter Darstellungsweise lediglich zwei Funktionselemente 12 und 13 zu sehen, die auf dem Hauptrahmen 1 befestigt sind.The locomotive housing 9 is on the top of the main frame 1 attached, which in the between the two driver's cab 10 and 11 located area is shown broken. In this Area are in a very simplified representation only two functional elements 12 and 13 can be seen on the main frame 1 are attached.

Die Befestigung besteht dabei aus rahmenfesten Anschlagelementen 14, 15, 16 und 17 und zwischen diesen und den Funktionselementen 12 und 13 angeordneten Energieverzehrelementen 18, 19, 20 und 21.The attachment consists of frame-fixed stop elements 14, 15, 16 and 17 and between them and the functional elements 12 and 13 arranged energy dissipation elements 18, 19, 20 and 21.

Auf der Unterseite befinden sich weitere rahmenfeste Anschlagelemente 22,23,24 und 25, die jeweils Energieverzehrelemente 26,27, 28 und 29 tragen. Die Energieverzehrelemente sind jeweils im Horizontalabstand zu den Endbereichen der Drehgestellrahmen 6 und 7 angeordnet. There are further frame-fixed stop elements on the underside 22,23,24 and 25, the energy consumption elements, respectively Wear 26, 27, 28 and 29. The energy consumption elements are each at a horizontal distance from the end areas of the bogie frame 6 and 7 arranged.

An den beiden Enden des Hauptrahmens 1 der Lokomotive befinden sich jeweils zwei energieverzehrende Stauchelemente 30 und 31, auf denen herkömmliche Pufferelemente 32 und 33 befestigt sind. Die Stauchelemente 30 und 31 stellen energieverzehrende Elemente nach dem Stand der Technik dar, wie er z.B. in der DE 196 35 221 beschrieben ist.At the two ends of the main frame 1 of the locomotive each have two energy-consuming compression elements 30 and 31, on which conventional buffer elements 32 and 33 are attached. The compression elements 30 and 31 represent energy-consuming elements according to the prior art, as e.g. in DE 196 35 221 is described.

Im Falle eines Aufpralls der Lokomotive mit einer Geschwindigkeit, die Aufprallenergien freisetzt, die über das Maß hinausgehen, das noch von den Pufferelementen 32 und 33 kompensiert werden kann, werden nach dem Stand der Technik, die zwischen den Pufferlementen 32 und 33 und dem Hauptrahmen 1 angeordneten energieverzehrenden Stauchelemente 30 und 31 zusammengedrückt. Da das Arbeitsaufnahmevermögen derartiger Stauchelemente 30 und 31 aber abhängt von deren Länge bzw. deren möglichen Verformungsweg, können diese zum Zweck der Steigerung des Energieaufnahmevermögens nicht beliebig verlängert werden, da sich ansonsten die Baulänge des Gesamtfahrzeugs in unerwünschter Weise erhöhen würde.In the event of a locomotive impact at a speed, releases the impact energies that go beyond measure that is still compensated by the buffer elements 32 and 33 can be, according to the prior art, between the Buffer elements 32 and 33 and the main frame 1 are arranged energy-consuming compression elements 30 and 31 compressed. Since the work capacity of such upsetting elements 30 and 31 but depends on their length or their possible deformation path, can do this for the purpose of increasing energy absorption not be extended indefinitely, otherwise the overall length of the entire vehicle in an undesirable manner would increase.

Die nach der Erfindung erzielte Erhöhung des Energieaufnahmevermögens wird ohne Verlängerung des Gesamtfahrzeugs erreicht. Bei einer auf den Hauptrahmen 1 einwirkenden außerordentlichen Aufprallbelastung werden in den auf dem Hauptrahmen 1 befestigten Funktionselementen 12,13 und in den Laufwerken bzw. den Drehgestellen 2,3 erhebliche Massenkräfte freigesetzt, die im Sinne einer Verschiebung der Funktionselemente 12,13 und der Laufwerke bzw. Drehgestelle 2,3 gegenüber dem Hauptrahmen 1 wirken.The increase in energy absorption capacity achieved according to the invention is achieved without extending the entire vehicle. At an extraordinary acting on the main frame 1 Impact loads are fastened in the on the main frame 1 Functional elements 12, 13 and in the drives or Bogies 2.3 released significant mass forces in the Sense of a displacement of the functional elements 12, 13 and Drives or bogies 2,3 opposite the main frame 1 Act.

Da nach der Erfindung definierte Verschiebungswege und eine eine Verschiebung zulassende Befestigung der Funktionselemente 12,13 und der Laufwerke vorgesehen sind, erfolgt bei Aufprallbelastung eine Verschiebung der Funktionselemente 12,13 und der Laufwerke bzw. Drehgestelle 2,3 entgegen der Aufprallrichtung, wobei auf dem Verschiebeweg je nach Aufprallrichtung die entsprechenden Energieverzehrelemente 18-21 und 26-29 unter Arbeitsaufnahme zusammengedrückt werden. Zusätzlich kann mit einer Klemmbefestigung der Funktionselemente 12,13 beim Verschieben durch Gleitreibung Arbeit aufgenommen werden. Die Anlenkung der Drehgestelle 2 und 3 am Hauptrahmen 1 ist soweit elastisch ausgeführt, daß ein Anschlag auf den Energieverzehrelementen 26-29 keine Schäden verursacht. Die Gesamtarbeit, die bei einem Aufprall aufgenommen wird ergibt sich aus der Summe der Arbeitsaufnahmen der verformten einzelnen Energieverzehrelemente.Since according to the invention displacement paths and a Fastening of the functional elements 12, 13 permitting displacement and the drives are provided takes place in the event of an impact a displacement of the functional elements 12, 13 and the drives or bogies 2,3 against the direction of impact, with the corresponding path depending on the direction of impact Energy consumption elements 18-21 and 26-29 taking up work be squeezed together. In addition, with a clamp of the functional elements 12, 13 when displaced by sliding friction Work to be started. The articulation of the bogies 2 and 3 on the main frame 1 is elastic so far, that a stop on the energy dissipation elements 26-29 none Caused damage. The total work involved in an impact recorded is the sum of the work intakes the deformed individual energy consumption elements.
