Abstract

The lateral stop consists of a roller and a contoured plate with fixed and elastic stops. The contour (8) of the elastic stop (6) is formed dependent upon that (9) of the fixed stop (5), so that lateral rigidity and lateral spring travel of the elastic stop are variable dependent upon the track curve. Lateral rigidity of the stop is defined by the shape of its base plate (7), while its lateral spring travel is varied dependent upon the differences between the contours of both stops.

Description

Die Erfindung betrifft einen bogenabhängigen Queranschlag für die Beschränkung des Querspiels zwischen Wagenkästen und Fahrwerken von Schienenfahrzeugen, bestehend aus einer Rolle und einer Konturplatte, welche einerseits einen Festanschlag aufweist und andererseits mit einem elastischen Anschlag versehen ist, wobei die Rolle wahlweise an dem Fahrwerk oder an dem Wagenkasten und die Konturplatte an dem jeweils anderen Fahrzeugteil angeordnet sein kann.
Es ist bereits eine gleisbogenabhängig gesteuerte Wagenkasten-Querspielbegrenzungseinrichtung für Schienenfahrzeuge (CH 670 227 A 5) bekannt, die aus Festanschlagelementen zur Begrenzung der maximalen Auslenkung zwischen Drehgestell und Wagenkasten sowie Elementen zur Abfederung kleinerer Auslenkungen besteht und Mittel vorsieht, um Querkräfte zwischen Drehgestell und Wagenkasten im wesentlichen asymptotisch in Funktion der relativen Querwege anwachsen zu lassen, wobei die Asymptote durch die Festanschlagelemente festgelegt ist. Weiterhin ist ein bogenabhängiger Queranschlag für die Beschränkung des Querspiels zwischen Wagenkasten und Drehgestell bei Schienenfahrzeugen (DE 44 25 562 C 1) bekannt, welcher aus einer Rolle und einer Konturplatte besteht und dadurch gekennzeichnet ist, daß die Rolle auf einem Umlenkteil gelagert ist, dessen anderes Hebelende an einem elastischen Anschlag anliegt. Diese konstruktive Lösung ist sehr aufwendig, da sie eine Vielzahl an Gelenken vorsieht.
Beide Lösungen weisen die Nachteile auf, daß große Bauräume, insbesondere für die Rolle, erforderlich und die Federkonstante sowie der Federweg des elastischen Anschlags immer in jeder Phase der Auslenkung gleich sind.
Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, einen elastischen, bogenabhängig wirkenden Queranschlag für die Beschränkung des Querspiels zwischen Wagenkästen und Fahrwerken von Schienenfahrzeugen zu entwickeln, welcher eine entsprechend dem Gleisbogen abhängige Ausführung von Federkonstante und Federweg der elastischen Elemente ermöglicht.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, indem die Kontur des elastischen Anschlags in Abhängigkeit zur Kontur des Festanschlages derart ausgebildet ist, daß die Quersteifigkeit und der Querfederweg des elastischen Anschlags in Abhängigkeit des Gleisbogens variabel ausführbar ist. Weiterhin ist erfindungsgemäß, daß die Quersteifigkeit des elastischen Anschlags durch die Form seiner Grundplatte definierbar ist und sich der Querfederweg durch die Differenz der Kontur des elastischen Anschlags zur Kontur des Festanschlags variieren läßt.
Die Vorteile der erfindungsgemäßen Lösung liegen insbesondere in der kompakten Bauform der Einrichtung bzw. in der Anpassung des elastisch gepufferten Querfederweges und der zugehörigen Federkonstante an den bogenabhängigen Wert des Querspiels zwischen dem Fahrwerk und dem Wagenkasten.The invention relates to a bow-dependent cross stop for restricting the transverse play between car bodies and undercarriages of rail vehicles, consisting of a roller and a contour plate, which on the one hand has a fixed stop and on the other hand is provided with an elastic stop, the roller optionally on the undercarriage or on the Car body and the contour plate can be arranged on the other vehicle part.
There is already a wagon-body-controlled cross-game limiting device for rail vehicles (CH 670 227 A 5), which consists of fixed stop elements for limiting the maximum deflection between the bogie and the body and elements for cushioning smaller deflections and provides means to prevent lateral forces between the bogie and the body in the to grow substantially asymptotically as a function of the relative cross paths, the asymptote being determined by the fixed stop elements. Furthermore, an arc-dependent cross stop for the limitation of the transverse play between the body and bogie in rail vehicles (DE 44 25 562 C 1) is known, which consists of a roller and a contour plate and is characterized in that the roller is mounted on a deflection part, the other Lever end rests on an elastic stop. This constructive solution is very complex because it provides a large number of joints.
Both solutions have the disadvantages that large installation spaces, in particular for the roller, are required and the spring constant and the spring travel of the elastic stop are always the same in every phase of the deflection.
The problem specified in the invention is based on the problem of developing an elastic, arch-dependent transverse stop for restricting the transverse play between car bodies and undercarriages of rail vehicles, which enables the spring elements and spring travel of the elastic elements to be designed in accordance with the track curve.
According to the invention the object is achieved in that the contour of the elastic stop is designed in dependence on the contour of the fixed stop in such a way that the transverse rigidity and the transverse spring travel of the elastic stop can be carried out variably depending on the track curve. Furthermore, it is according to the invention that the transverse rigidity of the elastic stop can be defined by the shape of its base plate and the transverse spring travel can be varied by the difference between the contour of the elastic stop and the contour of the fixed stop.
The advantages of the solution according to the invention lie in particular in the compact design of the device or in the adaptation of the elastically buffered transverse spring travel and the associated spring constant to the bow-dependent value of the transverse play between the chassis and the car body.

The invention will be explained in more detail using an exemplary embodiment. The drawings show in
Fig. 1:
a plan view of the cross stop
Fig. 2:
a side view of the cross stop

Wie aus den Fig. 1 und 2 ersichtlich, ist die Rolle 1 am Wagenkasten 2 gelagert und die Konturplatte 3 am Fahrgestellrahmen 4 befestigt. Beim gleisbogenabhängigen Ausdrehen des Fahrgestellrahmens 4 kann die Rolle 1 jede beliebige Position zwischen der in Fig. 1 dargestellten Lage im geraden Gleis und dem kleinsten Gleisbogenradius einnehmen. Die Konturplatte 3 weist beidseitig Festanschläge 5 und zwischen diesen den elastischen Anschlag 6 auf. Der elastische Anschlag 6 besteht vorzugsweise aus Gummi und ist mittels der Grundplatte 7 auf der Konturplatte 3 befestigt. Die Kontur 8 des elastischen Anschlags 5 ist so bemessen, daß der elastische Anschlag im geraden Gleis eine weichere Kennlinie der Federkonstante als im engeren Bogen aufweist. Die Festanschläge 5 weisen dagegen eine Kontur 9 auf, die derart ausgeführt ist, daß die Profilfreiheit des Wagenkastens in jedem Gleisbogen gewährleistet ist. As can be seen from FIGS. 1 and 2, the roller 1 is mounted on the body 2 and the contour plate 3 attached to the chassis frame 4. When dependent on the track curve Unscrewing the chassis frame 4, the role 1 between any position the position shown in Fig. 1 in a straight track and the smallest curve radius take in. The contour plate 3 has fixed stops 5 on both sides and between this the elastic stop 6. The elastic stop 6 is made preferably made of rubber and is on the contour plate 3 by means of the base plate 7 attached. The contour 8 of the elastic stop 5 is dimensioned so that the elastic Stop in the straight track a softer characteristic of the spring constant than in has a narrower arc. The fixed stops 5, however, have a contour 9, which is designed so that the profile freedom of the car body in each track curve is guaranteed.
