Bei der bekannten Heberlein'schen Frictionsschnellbremse, sowie bei ähnlichen Bremsen für die Fahrzeuge der Eisenbahnen geschieht immer die directe Uebertragung der Bewegung von einer auf der Radachse aufgekeilten Rolle auf die in dem Bremsapparat befindliche Frictionsrolle. Vorliegende Erfindung bezieht sich auf eine Neuerung, welche zum Schutz gegen den Einfiufs der Witterung auf den Oberfiächenzustand der Frictionsrolle bezw. der Achsenrolle dient, so dafs die sonst mit der Aenderung der Witterung verbundene Variation des Reibungscoefficienten vermieden wird, und besteht in der Einschaltung eines Frictionsringes, der so angeordnet ist, dafs die eingeschalteten, zur Uebertragungsbewegung mittelst Friction dienenden Flächen innerhalb des Apparates sich befinden, dem Einflüsse der äufseren Witterungsverhältnisse daher entzogen sind. With the well-known Heberlein friction quick brake, as well as with similar brakes for The vehicles of the railways always have the direct transfer of motion from a roller wedged on the wheel axle onto the friction roller located in the braking device. The present invention relates to an innovation which is used to protect against the Influence of the weather on the surface condition of the friction roller or the axle roller so that the variation of the coefficient of friction otherwise associated with the change in weather is avoided, and consists in the inclusion of a friction ring so is arranged so that the switched on, used for the transmission movement by means of friction There are areas within the device that are not exposed to the effects of external weather conditions.

In der beiliegenden Zeichnung, Fig. 1 bis 6, sind Anordnungen dargestellt, bei denen der auswechselbare Reibungsring auf der Achse des Fahrzeuges selbst angebracht ist, und ist die Anordnung an der ganzen Bremse in Fig. 7 gezeichnet. In the accompanying drawing, Fig. 1 to 6, arrangements are shown in which the replaceable friction ring on the axis of the The vehicle itself is attached, and the arrangement is drawn on the entire brake in FIG.

In Fig. ι greift um die zweitheilige, fest auf der Radachse, sitzende Nabe c der gleichfalls zweitheilige Frictionsring d, so dafs der letztere bei einer Bewegung der Radachse stets mitgenommen wird, und erst dann ruhig stehen bleibt, wenn der gesammte Bremsapparat durch die Welle B des Apparates (s. Fig. 7) in Thätigkeit gesetzt und die Bremse angezogen ist. Die Reibung findet hier an der inneren Peripherie des Reibungsringes d statt, und ist dieselbe deshalb, vor Schwankungen infolge ungünstiger Witterungsverhältnisse, insbesondere infolge von Eisbildung auf der Oberfläche der Rolle geschützt. Die auf der Achse aufgekeilte Rolle c ist in der beiliegenden Zeichnung in zwei Modificationen dargestellt, entweder ganz im Innern des Reibungsringes gelagert (s. Fig. 2, 4 und 6) oder den Reibungsring mit Flantschen umgreifend (s. Fig. i, 3 und 5). Die Oberfläche des Reibvmgsringes und der entsprechenden Frictionsrolle kann dabei sehr verschieden gestaltet werden. Entweder ist dieselbe rein cylindrisch (s. Fig. 1) oder mit Zähnen (s. Fig. 3 und 4) oder mit Rinnen (s. Fig. 2) versehen, oder auch gewölbt geformt, wie in Fig. 5 und 6 dargestellt. Diese sämmtlichen Anordnungen bezwecken, das Flachgleiten der Reibungsringe an ihrer Oberfläche zu verhindern und die Reibung von dem Einfiufs der Witterung unabhängig zu machen.In Fig. 1, the two-part hub c , which is firmly seated on the wheel axle, is encompassed by the two-part friction ring d, so that the latter is always carried along when the wheel axle moves, and only comes to a standstill when the entire braking device is driven by the shaft B of the apparatus (see Fig. 7) is activated and the brake is applied. The friction takes place here on the inner periphery of the friction ring d and is therefore protected from fluctuations due to unfavorable weather conditions, in particular due to the formation of ice on the surface of the roller. The roller c wedged on the axis is shown in two modifications in the accompanying drawing, either mounted entirely inside the friction ring (see FIGS. 2, 4 and 6) or encompassing the friction ring with flanges (see FIGS. 1, 3 and 5). The surface of the friction ring and the corresponding friction roller can be designed very differently. It is either purely cylindrical (see FIG. 1) or provided with teeth (see FIGS. 3 and 4) or with grooves (see FIG. 2), or it is also arched, as shown in FIGS. 5 and 6. The aim of all of these arrangements is to prevent the friction rings from sliding flat on their surface and to make the friction independent of the influence of the weather.
