Description

Die Erfindung betrifft eine Primärfederung für Schienenfahrzeuge nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a primary suspension for rail vehicles according to the preamble of claim 1.

Es ist bekannt (DE-OS 30 48 515), eine Primärfederung für Schienenfahrzeuge so zu gestalten, daß jedes Achslagergehäuse in Fahrzeuglängsrichtung beidseitig Tragarme aufweist und sich zwischen diesen Tragarmen und dem Drehgestellrahmen Federn befinden, von denen eine eine in senkrechter Richtung weiche Feder ist, während die andere Feder eine auf ihre horizontalen Federeigenschaften ausgelegte Feder ist, die aus zwei übereinanderliegenden nichtebenen Metallflächen besteht, zwischen denen sich eine Schicht aus elastomeren Material befindet. Diese bekannte Primärfederung hat den Vorteil, daß sie einerseits in senkrechter Richtung weich ist, weil die in senkrechter Richtung weiche Feder, die eine Schraubenfeder, eine Gasfeder oder auch eine Elastomerfeder sein kann, die ganze Federung in senkrechter Richtung übernimmt. Andererseits bestimmt die andere Feder, die ähnlich wie bei einem Achslenker, als Drehgelenk dient, und die auf ihre horizontalen Federeigenschaften ausgelegt ist und in senkrechter Richtung verhältnismäßig hart sein kann, die Elastizität in der horizontalen Ebene, wobei die Federeigenschaften in Fahrtrichtung - x-Richtung -und quer zur Fahrtrichtung - y-Richtung - unterschiedich groß sein können und weitgehend den jeweiligen Verhältnissen angepaßt werden können.It is known (DE-OS 30 48 515) to design a primary suspension for rail vehicles so that each axle bearing housing has support arms on both sides in the vehicle longitudinal direction and springs are located between these support arms and the bogie frame, one of which is a spring which is soft in the vertical direction, while the other spring is a spring designed for its horizontal spring properties, which consists of two superimposed non-planar metal surfaces, between which there is a layer of elastomeric material. This known primary suspension has the advantage that it is soft on the one hand in the vertical direction, because the spring which is soft in the vertical direction, which can be a coil spring, a gas spring or an elastomer spring, takes over the entire suspension in the vertical direction. On the other hand, the other spring, which serves as a pivot joint, similar to an axle control arm, and which is designed for its horizontal spring properties and can be relatively hard in the vertical direction, determines the elasticity in the horizontal plane, the spring properties in the direction of travel - x direction -and transverse to the direction of travel - y-direction - can be of different sizes and can be largely adapted to the respective conditions.

Diese bekannten Primärfederungen sind insbesondere für schnellfahrende Schienenfahrzeuge gut geeignet. Es hat sich jedoch gezeigt, daß die Steifigkeit dieser bekannten Primärfederung in x- und y-Richtung nicht in der wünschenswerten Breite variierbar ist, weil die Elastomerfeder neben den vertikalen Abstützkräften auch eine Verdrehung um die y-Achse aufnehmen muß, da ja die Elastomerfeder beim Einfedern der anderen in senkrechter Richtung weichen Feder als Drehgelenk dient.These known primary suspensions are particularly suitable for high-speed rail vehicles. However, it has been shown that the stiffness of this known primary suspension in the x and y directions cannot be varied in the desired width because the elastomer spring must also absorb a rotation about the y axis in addition to the vertical support forces, since the elastomer spring at Compression of the other spring, which is soft in the vertical direction, serves as a swivel joint.

Aufgabe der Erfindung ist es, die Elastomerfeder so zu gestalten, daß sie auch diese Verdrehung aufnehmen kann, ohne daß dabei der Vorteil aufgegeben wird, daß die horizontalen Federeigenschaften in x- und y-Richtung weitgehend einstellbar sind. Diese Aufgabe wird gelöst durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale. Die Unteransprüche geben weitere Ausführungsformen und Verbesserungen an.The object of the invention is to design the elastomer spring in such a way that it can also accommodate this twist, without giving up the advantage that the horizontal spring properties are largely adjustable in the x and y directions. This object is achieved by the features specified in the characterizing part of patent claim 1. The subclaims indicate further embodiments and improvements.

Dadurch, daß mindestens eine Elastomerschicht teilkugelschalenförmig ausgebildet ist und zwischen zwei Teilkugeloberflächen der angrenzenden Metallkörper liegt, erhält die Elastomerfeder die Eigenschaften eines Kugelgelenks, während durch die zusätzliche als ebene oder trogförmige Schicht ausgebildete elastomere Schicht die Elastizität in der horizontalen Ebene weitgehend variiert werden kann. Dabei kann die zusätzliche elastomere Schicht, wie dies an sich bekannt ist (DE-PS 1 755 875), aus zwei dachförmig gegeneinander geneigten Schichten oder auch aus zwei gegeneinander geneigten Schichten, zwischen denen sich eine horizontale Schicht befindet, oder auch aus mehreren gegeneinander geneigten Schichten bestehen, oder sie kann als Zylinderhalbschale ausgebildet sein. Durch diese Formgebung der zusätzlichen Schicht aus elastomeren Material sind alle in der Praxis erforderlichen Steifigkeiten und Steifigkeitsunterschiede in x- und y-Richtung erreichbar. Sind die Federwege bei der in senkrechter Richtung weichen Feder groß, so treten dementsprechend auch große Verdrehwinkel in der Elastomerfeder auf. Damit die Schubbeanspruchung in der teilkugelschalenförmig ausgebildeten Schicht aus elastomeren Material nicht zu groß wird, kann die Verdrehung auf mehrere konzentrisch zueinander angeordnete teilkugelschalenförmige Schichten verteilt werden. Da die Schubbeanspruchungen in den teilkugelschalenförmigen Elastomerschichten vom Kugelradius abhängen, können die Schichtdicken dem Kugelradius entsprechend verschieden groß sein, wobei sie vorteilhaft mit zunehmendem Kugelradius größer werden.Characterized in that at least one elastomer layer is part-spherical shell-shaped and lies between two part-spherical surfaces of the adjacent metal body, the elastomer spring receives the properties of a ball joint, while the elasticity in the horizontal plane can be largely varied by the additional elastomer layer formed as a flat or trough-shaped layer. The additional elastomeric layer, as is known per se (DE-PS 1 755 875), can consist of two layers inclined towards one another in a roof shape or also of two layers inclined towards one another, between which there is a horizontal layer, or also of several layers inclined towards one another Layers exist, or it can be designed as a cylinder half-shell. This shape of the additional layer of elastomeric material, all stiffnesses and differences in stiffness required in practice in the x and y directions can be achieved. If the spring travel is large for the spring, which is soft in the vertical direction, then correspondingly large torsion angles also occur in the elastomer spring. So that the shear stress in the partial spherical shell-shaped layer made of elastomeric material does not become too great, the twisting can be distributed over several partial spherical shell-shaped layers arranged concentrically to one another. Since the shear stresses in the partial spherical shell-shaped elastomer layers depend on the radius of the sphere, the layer thicknesses can vary according to the radius of the sphere, and they advantageously increase with increasing radius of the sphere.

Embodiments of a primary suspension according to the invention are shown in the drawings.
  • Fig. 1 shows a vertical partial section of a primary suspension according to the invention, in which the elastomer spring has only a partial spherical shell-shaped layer;
  • Fig. 2 shows a section along the line 11-11 in Fig. 1;

Bei der Ausführungsform nach Fig. 1 und 2 besitzt das Achslagergehäuse 1 beidseitig zwei Tragarme 2 und 3, die in Fahrzeuglängsrichtung x liegen. Der Drehgestellrahmen 13 bzw. der Wagenkasten stützt sich auf dem Tragarm 2 über eine Schraubenfeder 4 und auf dem Tragarm 3 über die Elastomerfeder 5 ab. Diese Elastomerfeder 5 besteht, wie dargestellt, aus einem Stahlteil 6 mit teilkugelförmiger Oberfläche und einem Stahlteil 7 mit teilkugelförmiger Aushöhlung und zwischen diesen Stahlteilen liegt eine Elastomerschicht 8. Zwischen der Unterseite des Stahlteils 7 und der Oberseite eines weiteren Stahlteils 9 liegt eine zusätzliche Elastomerschicht 10. Die Oberflächen der Stahlteile 7 und 9, an die die Schicht 10 anvulkanisiert ist, können grundsätzlich horizontal liegend eben sein. In diesem Fall ist die Federung in x-und y-Richtung gleich groß. Soll die Federung in x- und y-Richtung jedoch verschieden groß sein, so kann die Elastomerschicht auch trogförmig ausgebildet sein oder sie kann dachförmig gestaltet sein, wobei die Längsrichtung des Troges bzw. des Daches in x- oder in y-Richtung liegen kann, je nachdem in welcher dieser beiden Richtungen eine größere Elastizität erwünscht ist.In the embodiment according to FIGS. 1 and 2, the axle bearing housing 1 has two support arms 2 and 3 on both sides, which lie in the vehicle longitudinal direction x. The bogie frame 13 or the car body is supported on the support arm 2 via a helical spring 4 and on the support arm 3 the elastomer spring 5. As shown, this elastomer spring 5 consists of a steel part 6 with a part-spherical surface and a steel part 7 with a part-spherical cavity, and an elastomer layer 8 lies between these steel parts. The surfaces of the steel parts 7 and 9, to which the layer 10 is vulcanized, can in principle be horizontally flat. In this case, the suspension in the x and y directions is the same. However, if the suspension is to be of different sizes in the x and y directions, the elastomer layer can also be trough-shaped or it can be roof-shaped, the longitudinal direction of the trough or roof being in the x or y direction, depending on in which of these two directions greater elasticity is desired.

Bei der in Fig. 1 und 2 dargestellten Ausführungsform ist, wie insbesondere aus Fig. 2 zu entnehmen, die zusätzliche Elastomerschicht 10 trogförmig ausgebildet, wobei der Trog im wesentlichen einen U-förmigen, nach oben offenen Querschnitt besitzt. Die Trogachse verläuft in x-Richtung. Wie Fig. 2 weiterhin zu entnehmen, ist die Trogweite in x-Richtung nicht konstant, sondern sie nimmt von der Mitte der Elastomerfeder 5 nach beiden Richtungen der Trogachse hin ab. Der Federweg des Stahlteils 7 in horizontaler x-Richtung ist durch Anschläge 11, 12 begrenzt.In the embodiment shown in FIGS. 1 and 2, as can be seen in particular from FIG. 2, the additional elastomer layer 10 is trough-shaped, the trough essentially having a U-shaped cross section open at the top. The trough axis runs in the x direction. As can also be seen in FIG. 2, the trough width is not constant in the x direction, but rather decreases from the center of the elastomer spring 5 in both directions of the trough axis. The spring travel of the steel part 7 in the horizontal x direction is limited by stops 11, 12.

Fig. 3 zeigt eine Elastomerfeder 5',die in einer Primärfederung nach Fig. 1 anstelle der Elastomerfeder 5 verwendet werden kann. Bei dieser Ausführungsform der Elastomerfeder sind zwischen dem Metallteil 6' und dem Metallteil 7' zwei kugelkalottenförmige Elastomerschichten 8a' und 8b' vorgesehen, zwischen denen eine kugelschalenförmige Metallschicht 6a' liegt. Dabei ist die Dicke dl der Elastomerschicht 8a' etwas kleiner als die Dicke d2 der Elastomerschicht 8b' mit dem größeren Kugelradius. Die zusätzliche Elastomerschicht 10' zwischen den Metallteilen 7' und 9' ist auch bei dieser Ausführungsform trogförmig gestaltet und setzt sich aus im wesentlichen ebenen Teilschichten 10a',10b', 10c' zusammen, die gegeneinander geneigt angeordnet sind.FIG. 3 shows an elastomer spring 5 'which can be used in a primary suspension according to FIG. 1 instead of the elastomer spring 5. In this embodiment of the elastomer spring, between the metal part 6 'and the metal part 7' two spherical spherical elastomer layers 8a 'and 8b' are provided, between which a ball bowl-shaped metal layer 6a '. The thickness d1 of the elastomer layer 8a 'is somewhat smaller than the thickness d2 of the elastomer layer 8b' with the larger sphere radius. The additional elastomer layer 10 'between the metal parts 7' and 9 'is also designed trough-shaped in this embodiment and is composed of essentially flat partial layers 10a', 10b ', 10c', which are arranged inclined to one another.

Um die Federeigenschaften weiterhin zu variieren, können die kugelförmigen Oberflächen der Metallteile 6 und 7 bzw. 6' und 7' auch etwas exzentrisch zueinander angeordnet sein, so daß sich die Dicke der dazwischenliegenden Elastomerschicht von der Mitte nach den Rändern zu verändert. Zum Ausgleich der Schubbeanspruchung bei mehreren teilkugelschalenförmigen, konzentrisch zueinander angeordneten Elastomerschichten, können, statt die Schichten unterschiedlich dick zu machen, auch Elastomere mit unterschiedlicher Elastizität verwendet werden. Als Elastomere können natürlicher oder synthetischer Gummi oder gummielastische Kunststoffe verwendet werden, wobei Voraussetzung ist, daß sich das Elastomer mit Metallen fest verbinden läßt.In order to further vary the spring properties, the spherical surfaces of the metal parts 6 and 7 or 6 'and 7' can also be arranged somewhat eccentrically to one another, so that the thickness of the intermediate elastomer layer changes from the center to the edges. To compensate for the shear stress in several spherical shell-shaped, concentrically arranged elastomer layers, instead of making the layers of different thicknesses, elastomers with different elasticity can also be used. Natural or synthetic rubber or rubber-elastic plastics can be used as elastomers, provided that the elastomer can be firmly bonded to metals.
