Schienenfahrzeug-Bremsscheibe BeschreibungRail vehicle brake disc Description

Die Erfindung betrifft eine Schienenfahrzeug-Bremsscheibe, insbesondere aus Aluminium.The invention relates to a rail vehicle brake disc, in particular made of aluminium.

Die Reibflächen von Bremsscheiben für Schienenfahrzeuge sind nach dem Stand der Technik glatte Reibflächen, die lediglich bei bestimmten Einsatzfällen (z.B. bei Radbremsscheiben) beispielsweise Bohrungen aufweisen. Dem Problem der Nässeempfindlichkeit wird hauptsächlich dadurch begegnet, daß man versucht, Werkstoff und Geometrie der Bremsscheibe so auszulegen, daß die Nässeempfindlichkeit abnimmt.According to the current state of the art, the friction surfaces of brake discs for rail vehicles are smooth friction surfaces that only have holes in certain applications (e.g. wheel brake discs). The problem of moisture sensitivity is mainly addressed by trying to design the material and geometry of the brake disc in such a way that moisture sensitivity is reduced.

Die Neuerung zielt darauf ab, das Nässeverhalten der gattungsgemäßen Bremsscheiben zu verbessern.The innovation aims to improve the wet behaviour of the generic brake discs.

Die Neuerung erreicht dieses Ziel durch den Gegenstand des Anspruches 1. Die Neuerung beruht auf dem Einsatz von Nuten, die - in geeigneter Lage und Geometrie auf der Reibfläche angeordnet - Wasser nach Art einer "Drainagewirkung" ableiten.The innovation achieves this goal through the subject matter of claim 1. The innovation is based on the use of grooves which - arranged in a suitable position and geometry on the friction surface - drain water in the manner of a "drainage effect".

Die Nuten auf der Reibfläche weisen bevorzugt eine Breite von 2-20 mm auf, als besonders vorteilhaft haben sich Nuten einer Breite zwischen 5 und 10 mm erwiesen. Die Tiefe der Nuten liegt ferner bevorzugt zwischen ca. 2 mm und - als maximaler Grenze - dem Verschleißgrenzmaß. Die Anordnung der Nuten auf der Reibfläche erfolgt bevorzugt winklig zur Tangente zum Innenumfang der Scheibe, insbesondere ist ein Winkel zwischen 30 und 60° vorteilhaft. Die Nuten könnenThe grooves on the friction surface preferably have a width of 2-20 mm, grooves with a width of between 5 and 10 mm have proven to be particularly advantageous. The depth of the grooves is also preferably between approx. 2 mm and - as a maximum limit - the wear limit. The arrangement of the grooves on the friction surface is preferably at an angle to the tangent to the inner circumference of the disk, in particular an angle between 30 and 60° is advantageous. The grooves can

ferner auf der Reibfläche gerade, kreisbogenförmig oder mit einer sonstigen beliebigen Krümmung verlaufen.Furthermore, they can run straight, in a circular arc or with any other curvature on the friction surface.

Nachfolgend wird die Neuerung anhand der Zeichnung näher beschrieben. Es zeigt: Fig. 1 eine schematische Ansicht der Neuerung;The innovation is described in more detail below using the drawing. It shows: Fig. 1 a schematic view of the innovation;

Fig. 2 verschiedene Ansichten der Querschnittsgeometrien der erfindungsgemäß vorgesehenen Nuten.Fig. 2 different views of the cross-sectional geometries of the grooves provided according to the invention.

Fig. 1 zeigt eine Bremsscheibe 1, deren Reibflächen 3 beidseitig mit vier Nuten 2 versehen sind, die jeweils in einem Winkel von ca. 30° zu den Innen-Umfangstangenten angeordnet sind. Es hat sich als besonders zweckmäßig erwiesen, mindestens 3, vorzugsweise 6-18 Nuten vorzusehen. Bei Regen bildet sich ein Nässefilm, der im vorliegenden Fall nicht zum Aufschwimmen des Belages führt, da die Drainagenuten 2 das Wasser abführen und abschleudern. Die Erfindung eignet sich damit insbesondere auch für Aluminiumbremsscheiben und ist einfach und kostengünstig realisierbar. Die Nuten der Fig. 1 sind gleichsinnig angeordnet, es kann jedoch auch - je nach Einsatzzweck - eine gegensinnige Anordnung gewählt werden.Fig. 1 shows a brake disk 1, the friction surfaces 3 of which are provided on both sides with four grooves 2, each of which is arranged at an angle of approximately 30° to the inner circumferential tangents. It has proven to be particularly useful to provide at least 3, preferably 6-18 grooves. When it rains, a film of moisture forms, which in this case does not lead to the pad floating, since the drainage grooves 2 drain the water away and throw it off. The invention is therefore particularly suitable for aluminum brake disks and can be implemented simply and inexpensively. The grooves in Fig. 1 are arranged in the same direction, but - depending on the intended use - an opposite arrangement can also be selected.

Fig. 2 veranschaulicht verschiedene Nutenvarianten: in Fig. 2a ist die Nute als rechtwinklige, in Fig.2b als spitzwinklige und in Fig. 2d als runde Ausnehmung ausgebildet. In Fig. 2c und e sind jeweils die Kanten der Nuten abgerundet.Fig. 2 illustrates different groove variants: in Fig. 2a the groove is designed as a rectangular recess, in Fig. 2b as an acute-angled recess and in Fig. 2d as a round recess. In Fig. 2c and e the edges of the grooves are rounded.
