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.The invention relates to a bow-dependent cross stop for the restriction the cross-game 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 has and on the other hand is provided with an elastic stop, wherein the role either on the chassis or on the car body and the contour plate can be arranged on the other vehicle part.

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.It is already a wagon body cross-play limiting device controlled depending on the track curve for rail vehicles (CH 670 227 A 5) known, made of fixed stop elements to limit the maximum deflection between the bogie and car body and elements for cushioning small deflections and provides means to substantially apply transverse forces between the bogie and the body to grow asymptotically as a function of the relative cross paths, the asymptote is determined by the fixed stop elements. Furthermore is a bow-dependent cross stop for the limitation of the cross game between Car body and bogie in rail vehicles (DE 44 25 562 C 1) known, which consists of a roller and a contour plate and is characterized is that the roller is mounted on a deflecting part, the other end of the lever rests against an elastic stop. This constructive solution is very complex, because it provides a variety of joints.

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.Both solutions have the disadvantages that large installation spaces, in particular for the role required and the spring constant as well as the travel of the elastic Attacks are always the same in every phase of the deflection.

Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, einen verbesserten elastischen, bogenabhängig wirkenden Queranschlag für die Beschränkung des Querspiels zwischen Wagenkästen und Fahrwerken von Schienenfahrzeugen zu entwickeln,The invention specified in the claim is based on the problem of a improved elastic, arch-dependent cross stop for the limitation of Cross-game between car bodies and chassis of rail vehicles too develop,

Erfindungsgemäß wird die Aufgabe durch die Merkmalkombination von Anspruch 1 gelöst. According to the invention the task is accomplished by solved the combination of features of claim 1.

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.Furthermore, according to the invention, that the transverse rigidity of the elastic stop due to the shape of its base plate is definable and the transverse spring travel is determined by the difference in the contour of the elastic stop can vary to the contour of the fixed stop.

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 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 arc-dependent value of the Cross-game between the chassis and the body.

Die Erfindung soll nachfolgend an einem Ausführungsbeispiel näher erläutert werden. Hierbei zeigen die Zeichnungen in

The invention will be explained in more detail using an exemplary embodiment. The drawings show in
Fig. 1:
a top 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. With track curve dependent 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 curve is guaranteed.
