Description
Radtaster an Eisenbahngleisen, beidenenrechtwinklig zur Fahrschiene eine oder mehrere Radauflauffedern angeordnet sind, die zur Steuerung von Stromschlüssen dienen, haben die Eigenart, daß die verwendeten Auflauffedern verhältnismäßig groß und schwer sein müssen, da sie an ihrem der Schiene abgekehrten Ende fest im Tragkörper eingespannt sind, so daß sie über ihre ganze Länge die für den Raddruck erforderliche Vorspannung ihrer der Fahrschiene zugekehrten freien Enden erzeugen.Wheel buttons on railroad tracks, both at right angles one or more wheel run-up springs are arranged for the running rail, which are used for control are used by electric circuits, have the peculiarity that the overrun springs used are proportionate must be large and heavy, as they are firmly attached to the end facing away from the rail Support body are clamped so that they are required for the wheel pressure over their entire length Generate bias of their facing the rail free ends.
Außerdem müssen hierbei die von den Auflauffedern gesteuerten Kontakte nahe den Auflaufenden der Federn angeordnet sein, um die Wegverluste beim Befahren klein zu halten. Das bedingt eine große Bauhöhe des Radtasters in der Nähe der Schiene, was häufig unerwünscht ist.In addition, the contacts controlled by the overrun springs must be close to the overrun ends the springs be arranged in order to keep the loss of travel when driving on small. This requires a large overall height of the wheel button in the vicinity of the rail, which is often undesirable is.
Ferner erhalten die von den Federn gesteuerten Kontakte besonders bei hohen Fahrgeschwindigkeiten heftige Stöße, die zu Kontaktprellungen führen und damit Unsicherheiten beim Betrieb der von den Kontakten abhängigen Relais 0. dgl. zur Folge haben.Furthermore, the contacts controlled by the springs are maintained especially at high driving speeds violent shocks that lead to contact bruises and thus uncertainties during operation the relay dependent on the contacts 0.
Die Erfindung bezieht sich auf solche Radtaster mit federndem Auflaufhebel, die in ihrem mittleren Teil auf einer drehbaren Achse gelagert sind. Um hierbei die genannten Übelstände zu vermeiden, wird gemäß der Erfindung die Anordnung so getroffen,, daß das der Schiene abgekehrte Ende des aus einer oder mehreren geblätterten Federn 5 gebildeten Radauflaufhebels an einem ortsfesten Anschlag 12 anliegt und die Stromschlußeinrichtung 15, 16 durch einen an der Mittelfassung 13 der Feder angeordneten Kontakthebel 7 betätigt wird.The invention relates to such wheel buttons with a resilient overrun lever, which are shown in their central part are mounted on a rotatable axle. To this end the abuses mentioned to avoid, according to the invention, the arrangement is made so that that of the rail remote end of the wheel run-up lever formed from one or more leafed springs 5 rests against a stationary stop 12 and the current connection device 15, 16 by a arranged on the central socket 13 of the spring Contact lever 7 is actuated.
Der Gegenstand der Erfindung ist in den Abbildungen beispielsweise erläutert, undzwar zeigt Fig. ι den Radtaster in Ruhestellung und Fig. 2 die Lage der Feder, in der diese durch ein Rad belastet ist.The object of the invention is in the figures for example explained, and indeed FIG. 1 shows the wheel button in the rest position and FIG. 2 the position of the spring in which it is loaded by a wheel.
Im Gehäuse 4, das fest mit der Fahrschiene 1 durch Trageisen 2 und Klemmplatten 3 verschraubt ist, sind eine oder mehrere Auflauffedern 5 auf einer gemeinsamen, parallel zum Gleis verlaufenden, ortsfest angeordneten Achse 6 gelagert. Jede Auflauffeder trägt zweckmäßig auf ihrer Mittelfassung 13 einen federnden Übertragungshebel 7, der in der Ruhestellung über Kontaktfeder 15 eine Leitungsverbindung 8-9 und' in der befahrenen Stellung über Kontaktfeder 16 eine Leitungsverbindung 8-10 herstellt.In the housing 4, which is firmly screwed to the running rail 1 by means of supporting iron 2 and clamping plates 3 is, one or more overrun springs 5 are on a common, stationary axis 6 running parallel to the track stored. Each run-up spring expediently carries a resilient transmission lever on its central socket 13 7, which in the rest position via contact spring 15 has a line connection 8-9 and 'in the driven position via contact spring 16 establishes a line connection 8-10.
Unter dem Druck des Rades 14 (Fig. 2) wird das vordere Ende der Feder 5 von der Anschlagleiste 11 getrennt und niedergedrückt, während das rückwärtige Ende an dem Anschlag 12 des Gehäuses unverändert liegenbleibt. Durch die veränderte gegenseitige Höhenlage der beiden Federenden nimmt auch die Mittelfassung, da beide Federhälften gleichmäßig an der Durchbiegung teilnehmen, eine andere Schräglage ein, so daß nunmehr, durch den Übertragungshebel 7 veranlaßt, der Arbeitsstromschluß 8-10 über Kontaktfeder 16 hergestellt und der Ruhestromschluß über Kontaktfeder 15 unterbrochen wird.Under the pressure of the wheel 14 (Fig. 2) is the front end of the spring 5 separated from the stop bar 11 and depressed while the rear end remains unchanged against the stop 12 of the housing. Through the changed mutual height of the two spring ends also takes the middle version, there both halves of the spring participate equally in the deflection, set a different incline, so that now, caused by the transmission lever 7, the working current connection 8-10 over Contact spring 16 produced and the closed-circuit current via contact spring 15 is interrupted.
Sowohl durch die federnde Aufnahme des Radstoßes als auch dessen federnde Übertragung von der Mittelfassung der Feder 5 auf die Kontaktteile findet ein prellungsfreies Umschalten der Kontaktleitungen statt.Both through the resilient mounting of the wheel joint and its resilient transmission from the central version of the spring 5 to the contact parts there is a bounce-free switchover the contact lines instead.
