Description

Die im Eisenbahnwesen gegen Stromübertragung verwendeten Isolierlaschen befriedigen nicht. Alle bisher entwickelten Isolierlaschen bestehen bis auf die Preßholzlaschen aus mehreren Einzelteilen, und zwar den Stahllaschenteilen und den Isolierbeilen. Sowohl die Preßholzlaschen als auch die die Stahllaschen umkleidenden Isolierstoffe haben gegenüber den im Eisenbahnbetrieb auftretenden Beanspruchungen unzureichende mechanische Eigenschaften, so claß sie häufig ausgewechselt werden müssen-.The insulating tabs used in railways to prevent the transmission of electricity do not satisfy. All insulation tabs developed so far exist except for Preßholzlaschen from several individual parts, namely the steel plate parts and the Insulating hatchets. Both the pressed wood tabs and those cladding the steel tabs Insulating materials have to deal with the stresses that occur in railway operations insufficient mechanical properties, so they are often replaced have to-.

Diese Mängel sollen durch den Gegenstand! der Urfindung ausgeschaltet werden.These defects are supposed to be caused by the object! the original invention turned off will.

Das Wesen der Erfindung besteht darin, Stahlteile durch Aufvulkanisieren von Gummi oder durch andere technische Maßnahmen fest zu einer Isolierlasche zu verbinden, wobei die Bindemittel gleichzeitig als Isolierung wirken. Hierdurch soll die unmittelbare Beanspruchung des Isoliermaterials durch die Schiene ausgeschaltet und damit die Widerstandsfähigkeit des Isolierstoffes erhöht werden. Außerdem fallen bei dieser Isolierlaschenkonstruktion die sonst üblichen vielen Einzelteile fort. Gegenüber den Preßholzlaschen haben Isolierlaschen auf Stahlgrundlage den Vorteil der weit größeren Elastizität. In Abb. i und z sind Ausführungsbeispiele einer Isolierlasche gezeigt. Die Laschen haben jeweils einen durchgehenden Stahlkern K und Stahlteile S, die an der Schienenstoßstelle auf etwa i cm unterbrochen sind, damit die Stromübertragung am Stoß nicht möglich ist.The essence of the invention consists in firmly connecting steel parts by vulcanizing rubber or by other technical measures to form an insulating tab, the binding agents at the same time acting as insulation. This is intended to eliminate the direct stress on the insulating material from the rail and thus to increase the resistance of the insulating material. In addition, the otherwise usual many individual parts are omitted with this insulating tab construction. Compared to pressed wood straps, steel-based insulating straps have the advantage of far greater elasticity. In Fig. I and z, embodiments of an insulating tab are shown. The brackets each have a continuous steel core K and steel parts S, which are interrupted to about 1 cm at the rail joint so that the transmission of current at the joint is not possible.

PATENTANSPRUCH: Schienenstoßlaschen aus Stahl mit inneren Isolationsschichten, dadurch gekennzeichnet, daß Stahleinzelteile (K und S) zu einem Laschenkörper zusammengesetzt werden, wobei an den Berührungsflächen elektrisch isolierende Schichten einbracht sind, z. B. Gummi, die nach beiden Seiten hin eine feste Haftverbindung mit den Stahlteilen haben. PATENT CLAIM: Rail joint plates made of steel with inner insulation layers, characterized in that individual steel parts (K and S) are put together to form a plate body, with electrically insulating layers being introduced at the contact surfaces, e.g. B. rubber, which have a firm adhesive bond with the steel parts on both sides.
