Description

Die Erfindung betrifft eine Stütz- und Führeinrichtung zur Lagerung eines Stoßbalkens im Untergestell eines Schienenfahrzeugs nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a support and guide device for mounting a bumper beam in the underframe of a rail vehicle according to the preamble of patent claim 1.

Aus der DE-AS 15 30 165 ist ein Untergestell für ein zweiachsiges, drehgestelloses Schienenfahrzeug mit einem Stoßbalken bekannt, der gegenüber dem die Gewichte des Wagenkastens und der Zuladung aufnehmenden Untergestell unter Zwischenschaltung mindestens eines Stoßdämpfers längsverschiebbar gelagert ist, und mit seiner Unterseite auf Stützglieder des Untergestells abgestützt ist, wobei der Stoßbalken mit seitlichem Spiel und unter Einhalten eines Zwischenraumes zwischen seiner Oberseite und der Oberseite des Untergestells gelagert ist, derart, daß der Stoßbalken bei Biegebeanspruchung des Untergestells weitgehend unbeaufschlagt bleibt. Dazu ist der Stoßbalken als offenes Kastenprofil mit einem als liegendes Rechteck ausgebildeten Querschnitt ausgeführt und die Stützglieder sind als mit gegenseitigem Längsabschnitt im Bereich der unteren Längskanten des Stoßbalkens angeordnete Stützkonsole ausgebildet. Durch diese Ausbildung wird in vertikaler Ebene eine relativ große Biegeweichheit und in horizontaler Ebene eine relativ große Biegesteifigkeit des Stoßbalkens erzielt Dieses Biegeverhalten des Stoßbalkens verhindert einerseits bei vertikalen Durchbiegungen des wegen einer Anpassung an Gleisunebenheiten biegeweichem Untergestells und andererseits bei in horizontaler Ebene wirkenden Beanspruchungen des Stoßbalkens, beispielsweise durch exzentrischer Pufferkräfte im Betrieb mit Seitenpuffern Verklemmungen zwischen dem Untergestell und dem Stoßbalken.From DE-AS 15 30 165 a base frame for a biaxial, bogie-less rail vehicle with a bumper beam is known, which is longitudinally displaceable relative to the base frame receiving the weights of the car body and the load with the interposition of at least one shock absorber, and with its underside on supporting members of the Supported undercarriage, the bumper beam is supported with lateral play and while maintaining a space between its top and the top of the base frame, such that the bumper beam remains largely unloaded when the base frame is subjected to bending stress. For this purpose, the bumper beam is designed as an open box profile with a cross section designed as a lying rectangle, and the support members are designed as a support bracket arranged with a mutual longitudinal section in the region of the lower longitudinal edges of the bumper beam. With this design, a relatively high degree of flexural softness is achieved in the vertical plane and a relatively large degree of flexural rigidity of the impact beam in the horizontal plane. for example, due to eccentric buffer forces in operation with side buffers jamming between the underframe and the bumper beam.

Verklemmungen zwischen dem Stoßbalken und seiner Aufnahme im Untergestell werden weiterhin dadurch vermieden, daß der Stoßbalken nicht durchlaufend auf dem Untergestell abgestützt wird, sondern auf Stützgliedern, die als mit gegenseitigem Längsabstand im Bereich der unteren Längskante des Stoßbalkens angeordnete Stützkonsolen ausgebildet sind.Jamming between the bumper beam and its inclusion in the base frame are further avoided in that the bumper beam is not continuously supported on the base frame, but on support members which are designed as support brackets arranged with a mutual longitudinal distance in the region of the lower longitudinal edge of the bumper beam.

Für lange Schienenfahrzeuge gewährleistet die vorstehend beschriebene Ausbildung wegen der großen Anzahl von notwendigen Stützgliedern die Rückstellung des Stoßbalkens nicht mehr sicher Bei Drehgestellfahrzeugen ist der zur Verfügung stehende Einbauraum für den Stoßbalken über dem Drehgestellbereich extrem knapp bemessen und erfordert eine an diese Einschränkung angepaßte, flache Bauweise.For long rail vehicles, the design described above no longer ensures the resetting of the bumper beam due to the large number of necessary support members. With bogie vehicles, the space available for the bumper beam above the bogie area is extremely tight and requires a flat design adapted to this restriction.

Der Erfindung liegt die Aufgabe zugrunde, eine Stütz- und Führeinrichtung zur Lagerung eines Stoßbalkens in einem Untergestell eines Schienenfahrzeugs zu schaffen, die auch bei langen Schienenfahrzeugen ein sicheres Rückstellen des Stoßbalkens gewährleistet und die den beengten zur Verfügung stehenden Bauraum im Untergestell berücksichtigt.The invention has for its object to provide a support and guide device for storing a bumper beam in a base frame of a rail vehicle, which ensures a safe resetting of the bumper beam even in long rail vehicles and which takes into account the cramped space available in the base frame.

Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst. Zweckmäßige Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 5 beansprucht.This object is achieved by the features specified in claim 1. Appropriate developments of the invention are claimed in claims 2 to 5.

Im Untergestell 1 des dargestellten Ausführungsbeispiels ist ein sich über die gesamte Fahrzeuglänge erstreckender Stoßbalken 2, der an seinen Enden mit Kopfträgern 3 versehen ist, in der Längsmitte des Untergestells 1 innerhalb eines Freiraums im Untergestell 1 längsverschiebbar gelagert.In the underframe 1 of the exemplary embodiment shown, a bumper beam 2, which extends over the entire length of the vehicle and is provided with head supports 3 at its ends, is mounted in the longitudinal center of the underframe 1 within a free space in the underframe 1 and is longitudinally displaceable.

Die Kopfträger 3 sind entweder zur Aufnahme einer Zugvorrichtung 4a und zweier Seitenpuffer 4b oder zur Aufnahme einer nicht dargestellten Mittelpufferkupplung mit oder ohne Seitenpuffer 4b vorgesehen.The head supports 3 are provided either for receiving a pulling device 4a and two side buffers 4b or for receiving a central buffer coupling (not shown) with or without side buffers 4b.

Der Stoßbalken 2 ist als offenes Kastenprofil mit zwei bis zu den Kopfträgern 3 durchlaufenden Stoßbalkenlangträgern 5a und 5b ausgeführt, die in bestimmten Abständen durch Querstreben 6 miteinander verbunden sind.The impact beam 2 is designed as an open box section with two impact beam long beams 5a and 5b which extend through to the head girders 3 and which are connected to one another at certain intervals by transverse struts 6.

Die Stoßbalkenlangträger 5a und 5b weisen eine durchlaufende nach außen zur Seite hin offene im Querschnitt ]-förmige Ausnehmung 7 auf. Die Ausnehmung 7 ist durch einen oberen Gurt 8 und einen unteren Gurt 9 sowie einen diese Gurte 8 und 9 verbindenden Steg 10 des Stoßbalkenlangträgers 5a bzw. 5b gebildet. Die Ausnehmungen 7 sind spiegelsymmetrisch zur Mittellängsebene des Stoßbalkens 2 angeordnet. Im Querschnitt bildet der Stoßbalken 2 somit ein als liegendes Rechteck ausgebildetes Kastenprofil mit seitlich vorstehenden oberen und unteren Gurten 8 und 9.The bumper beam long beams 5a and 5b have a continuous recess 7 -shaped in cross section] open to the side. The recess 7 is formed by an upper belt 8 and a lower belt 9 as well as a web 10 of the bumper beam 5a or 5b connecting these belts 8 and 9. The recesses 7 are arranged mirror-symmetrically to the central longitudinal plane of the bumper beam 2. In cross section, the impact beam 2 thus forms a box profile formed as a lying rectangle with laterally protruding upper and lower straps 8 and 9.

Die Stoßbalkenlangträger 5a und 5b sind zweckmäßig aus in vielen Abmessungen und allgemein bekannten, handelsüblichen Doppel-T-Trägern (I-Träger) oder aus U-Profilträgern gebildet.The bumper beam 5a and 5b are expediently formed from many dimensions and well-known, commercially available double T-beams ( I -beams) or from U- profile beams.

Der Stoßbalken 2 ist gegen das Untergestell 1 durch Stütz- und Führelemente 11 abgestützt und geführt. Mindestens im Bereich zwischen den Kopfsektionen 12 des Untergestells 1, die den Drehgestellbereich umfassen, sind die Stütz- und Führelemente 11 innerhalb der Ausnehmungen 7 angeordnet. Dazu sind die Stütz- und Führelemente 11 an Trägern des Untergestells 1 jeweils mittels eines Lagerbocks 13 befestigt und ragen senkrecht zum Stoßbalkenlangträger 5a, 5b in die durch die Gurte 8 und 9 sowie den Steg 10 gebildete Ausnehmung 7 im Stoßbalken 2.The bumper beam 2 is supported and guided against the underframe 1 by supporting and guiding elements 11. At least in the area between the head sections 12 of the underframe 1, which comprise the bogie area, the support and guide elements 11 are arranged within the recesses 7. For this purpose, the supporting and guiding elements 11 are each fastened to supports of the base frame 1 by means of a bearing block 13 and project perpendicular to the bumper beam 5a, 5b into the recess 7 in the bumper beam formed by the belts 8 and 9 and the web 10.

Als Stütz- und Führelemente 11 sind Gleitlager 111 und Wälzlager 112 vorgesehen.Plain bearings 111 and roller bearings 112 are provided as support and guide elements 11.

Zwischen dem Untergestell 1 und dem in ihm längsverschieblich gelagerten Stoßbalken 2 ist eine Energieverzehr- und Rückstelleinrichtung 14 angeordnet, die relative Längsbewegungen des Stoßbalkens 2 gegenüber dem Untergestell 1 bedämpft und ein Rückstellen des Stoßbalkens 2 in seine Ausgangslage bewirkt.An energy dissipation and resetting device 14 is arranged between the underframe 1 and the shock beam 2 mounted longitudinally displaceably in it, which dampens relative longitudinal movements of the shock beam 2 relative to the underframe 1 and causes the shock beam 2 to be reset to its initial position.

Zwischen den als Gleitlager 111 ausgeführten Stütz- und Führelementen 11 und den Gurten 8 und 9 sowie dem Steg 10 der Stoßbalkenlangträger 5a, 5b sind Gleitstücke 17 angeordnet. Die Gleitstücke 17, die entweder am Stoßbalken 2 oder am Untergestell 1 bzw. an den Stütz- und Führelementen 11 befestigt sind, sind mit einstellbarem Spiel in horizontaler und vertikaler Richtung gegeneinander angeordnet. Die Gleitlager 111 werden daher im unbeaufschlagten Zustand nicht mit Kräften aus dem Gewicht des Stoßbalkens 2 belastet.Sliders 17 are arranged between the support and guide elements 11 designed as slide bearings 111 and the belts 8 and 9 and the web 10 of the bumper beam 5a, 5b. The sliders 17, which are attached either to the bumper beam 2 or to the underframe 1 or to the support and guide elements 11, are arranged against one another with adjustable play in the horizontal and vertical directions. The plain bearings 111 are therefore not loaded with forces from the weight of the impact beam 2 in the unloaded state.

Die als Wälzlager 112 ausgebildeten Stütz- und Führelemente 11 stützen im unbeaufschlagten Zustand des Stoßbalkens 2 den Stoßbalken 2 mit ihren Außenringen 112a an der Innenseite des oberen Gurtes 8 ab. Gegenüber dem unteren Gurt 9 ist der Außenring 112a auf Abstand gehalten.The support and guide elements 11 designed as roller bearings 112 support the impact beam 2 with their outer rings 112a on the inside of the upper belt 8 in the unloaded state of the impact beam 2. The outer ring 112a is kept at a distance from the lower belt 9.

Zur Einstellung der vorgesehenen Spiele zwischen dem Stoßbalken 2 und der Stütz- und Führelemente 11 sind die Lagerböcke 13 für die Stütz- und Führelemente 11 seiten- und höhenverstellbar am Untergestell 1 befestigt.To set the intended games between the bumper beam 2 and the supporting and guiding elements 11, the bearing blocks 13 for the supporting and guiding elements 11 are attached to the underframe 1 so that they can be adjusted in terms of side and height.

Oberhalb des Untergestells 1 ist ein Boden 15 und für geschlossene Eisenbahngüterwagen ein nicht dargestellter Aufbau angeordnet.Above the underframe 1 there is a floor 15 and a structure, not shown, for closed rail freight wagons.

Im Ausführungsbeispiel ist der Stoßbalken 2 im Bereich der Kopfsektionen 12 durch Gleitlager 16 anderer Bauart als die Gleitlager 111 im Untergestell 1 abgestützt und geführt. Die Gleitflächen der Gleitlager 111 und 16 sind mit Gleitstücken 17 und/oder Gleitschienen 18 aus verschleißfestem Stahl (Gleitstahl) belegt.In the exemplary embodiment, the impact beam 2 is supported and guided in the area of the head sections 12 by plain bearings 16 of a different construction than the plain bearings 111 in the base frame 1. The sliding surfaces of the sliding bearings 111 and 16 are covered with sliding pieces 17 and / or sliding rails 18 made of wear-resistant steel (sliding steel).

Im Ausführungsbeispiel sind die Stütz- und Führelemente 11 bezüglich einer Querebene jeweils paarig angeordnet und jeweils von gleicher Bauart, entweder als Gleitlager 111 oder Wälzlager 112 ausgeführt, wobei das erste Stütz- und Führelement 11 des Paares in die Ausnehmung 7 des ersten Stoßbalkenlangträgers 5a greift und das zweite Stütz- und Führelement 11 des Paares in die Ausnehmung 7 des zweiten Stoßbalkenlangträgers 5b greift.In the exemplary embodiment, the support and guide elements 11 are each arranged in pairs with respect to a transverse plane and each have the same design, either as a slide bearing 111 or roller bearing 112, the first support and guide element 11 of the pair engaging in the recess 7 of the first bumper beam 5a and the second supporting and guiding element 11 of the pair engages in the recess 7 of the second bumper beam 5b.

Es ist allerdings auch eine Lagerung des Stoßbalkens 2 ausführbar, bei der die Stütz- und Führelemente 11 mindestens bereichsweise am Stoßbalken 2 bezüglich eine Querebene versetzt zueinander angeordnet sind, derart, daß der Stoßbalken 2 in Längsrichtung betrachtet jeweils abwechselnd am Stoßbalkenlangträger 5a bzw. 5b gegen das Untergestell 1 gestützt und/oder geführt ist.However, it is also possible to mount the bumper beam 2, in which the support and guide elements 11 are at least partially offset on the bumper beam 2 with respect to a transverse plane, such that the bumper beam 2, viewed in the longitudinal direction, alternately on the bumper beam 5a and 5b, respectively the base 1 is supported and / or guided.
