Description
Weiche, insbesondere für Rillenschienengeleise. Es sind Weichen, insbesondere für Rillen schienengeleise bekannt, bei welchen die Zungengleitplatte aus einer Stahlplatte be steht, welche mittels eines unterhalb der Weichenzunge verlaufenden 3Ettelsteges auf die Weichenunterzugsplatte abgestützt ist.
Diese Ausführung hat den Nachteil, dass die Weichenunterzugsplatte die ganze Länge der Weichenzungenvorrichtung einnehmen muss, was die Konstruktion wesentlich ver teuert.
Vorliegende Erfindung betrifft Weichen, insbesondere für Rillenschienengeleise, deren Zungengleitplatte einen Mittelsteg aufweist, welcher auf dem Fuss einer der beiden Wei chenschienen abgestützt ist.
Ausführungsbeispiele des Erfindungsgegen standes sind in beiliegender Zeichnung dar gestellt.
Fig. 1 zeigt eine Draufsicht auf eine Aus führungsform des Erfindungsgegenstandes, wo bei die Weichenzunge nicht gezeichnet ist; Fig. 2 zeigt einen Schnitt nach der Linie I--I in der Fig. 1; Fig. 3 zeigt einen, der Fig. 2 gleicharti gen Schnitt durch eine erste und Fig. 4 einen solchen durch eine zweite Variante der in den Fig. 1 und 2 veranschaulichten Ausfüh rungsform.
In dieser Zeichnung bedeuten: a. eine Weichenzunge, b die Zungengleitplatte, c den Fuss der Stockschiene, d einen Mittelsteg, e Passplatten, f die Beischiene, .g Querrippen.
Eine den beweglichen Teil der Weichen zunge a tragende Zungengleitplatte b liegt auf einem Mittelsteg d, welcher sich mittels der Passplatten e auf den Fuss c der Stock schiene abstützt.
Gemäss der in Fig. 3 dargestellten Aus führungsform bestehen die Zungengleitplatte b und der Mittelsteg d aus einem einzigen T- förmigen Walzprofil, z. B. aus einem Schie nenunterteil mit Fuss nach oben.
Zweckmässigerweise werden hierfür die bei der Herstellung der Weichenzungen aus einem Walzprofil, z. B. dem Profil Fz 180, anfallenden, sonst im -VGTeichenbau nicht brauchbaren Abschnitte verwendet.
Beim Ausführungsbeispiel nach Fig. 4 ist der abgetrennte Unterteil der Beischiene /' mit Fuss nach oben als Zungengleitplatte verwendet. Zur besseren Abstützung der Bei schiene können einige Querrippen g ange schweisst werden.
Der Mittelsteg kann durchgehend oder unterbrochen sein.
Der den Mittelsteg tragende Schienenfuss kann zur Verbesserung der Lastübertragung stellenweise verbreitert sein.
Switches, especially for grooved rail tracks. There are switches, in particular for grooved rail tracks, in which the tongue slide plate is made of a steel plate which is supported on the switch support plate by means of a 3Ettelsteg running below the switch tongue.
This design has the disadvantage that the switch support plate must occupy the entire length of the switch tongue device, which makes the construction considerably more expensive.
The present invention relates to points, in particular for grooved rail tracks, the tongue slide plate of which has a central web which is supported on the foot of one of the two white rails.
Embodiments of the subject matter of the invention are shown in the accompanying drawings.
Fig. 1 shows a plan view of an embodiment of the subject invention, where in the switch tongue is not shown; FIG. 2 shows a section along the line I - I in FIG. 1; Fig. 3 shows a, the Fig. 2 Gleicharti gene section through a first and Fig. 4 such a through a second variant of the Ausfüh illustrated in FIGS. 1 and 2 approximately.
In this drawing: a. a switch tongue, b the tongue slide plate, c the foot of the stick rail, d a central web, e fitting plates, f the side rail, g transverse ribs.
A tongue slide plate b carrying the movable part of the switch tongue a lies on a central web d, which is supported by means of the fitting plates e on the foot c of the stick rail.
According to the embodiment shown in Fig. 3, the tongue slide plate b and the central web d consist of a single T-shaped rolled profile, for. B. from a Schie nenunterteil with foot upwards.
Appropriately for this purpose, in the manufacture of the switch tongues from a rolled profile, z. B. the profile Fz 180, accruing, otherwise unusable in the -VGTeichenbau sections are used.
In the embodiment according to FIG. 4, the separated lower part of the side rail / 'is used with the foot upwards as a tongue slide plate. Some transverse ribs can be welded to provide better support for the side rail.
The central web can be continuous or interrupted.
The rail foot carrying the central web can be widened in places to improve the load transfer.
