Description

Scheibenbremse für kleinrädrige Schienenfahrzeuge Die Erfindung betrifft eine Scheibenbremse für kleinrädrige Schienenfahrzeuge. Bei derartigen Scheibenbremsen besteht die Schwierigkeit, Reibflächen genügender Größe unterzubringen. Es ist bereits vorgeschlagen worden, die Seitenflanken der Felge und des Radreifens eines Fahrzeugrades radial nach innen durch die Radialfläche eines Reibringes zu verbreitern und die hierdurch entstehende, breite Ringfläche als Reibfläche zu gebrauchen. Hierbei besteht jedoch die Schwierigkeit, Bremsbacken zu schaffen, die auf sie eingeleitete Druckkräfte günstig über die ganze Breite der aus Einzelflächen zusammengesetzten und daher eventuell in radialer Richtung unebenen Reibfläche zu verteilen vermögen.Disc brake for small-wheeled rail vehicles The invention relates a disc brake for small-wheeled rail vehicles. With such disc brakes there is the difficulty of accommodating friction surfaces of sufficient size. It is already has been proposed, the side flanks of the rim and the tire of a vehicle wheel to widen radially inward through the radial surface of a friction ring and the the resulting wide ring surface can be used as a friction surface. Here is however, the difficulty in creating brake shoes, the compressive forces applied to them favorable over the entire width of the composite from individual surfaces and therefore possibly be able to distribute uneven friction surface in the radial direction.

Der Erfindung liegt die Aufgabe zugrunde, eine Scheibenbremse der eingangs angeführten Art zu schaffen, welche eine ausreichende Reibfläche aufweist und bei welcher auf die Bremsbacken eingeleitete Druckkräfte günstig über die Breite der Reibfläche verteilt werden.The invention is based on the object of providing a disc brake To create the type mentioned at the beginning, which has a sufficient friction surface and at which pressure forces applied to the brake shoes are favorable across the width the friction surface are distributed.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß an einem Rad zumindest annähernd in einer Radialebene mehrere Reibringflächen mit unterschiedlichen Durchmessern vorgesehen sind, daß jeder Reibringfläche eine eigene Bremsbacke zugeordnet ist und daß die Bremsbacken zueinander um eine oder mehrere senkrecht zur Radachse angeordnete Achsen verschwenkbar mit einem an einem Bremsgestänge üblicher Art angelenkten Träger verbunden sind.This object is achieved according to the invention in that on one Wheel at least approximately in a radial plane several friction ring surfaces with different Diameters are provided that each friction ring surface is assigned its own brake shoe is and that the brake shoes to each other by one or more perpendicular to the wheel axis arranged axes pivotable with one articulated to a brake linkage of the usual type Beams are connected.

In der Zeichnung ist ein Ausführungsbeispiel gemäß der Erfindung schematisch dargestellt.An exemplary embodiment according to the invention is shown schematically in the drawing shown.

Das Rad eines kleinrädrigen Schienenfahrzeuges trägt an seiner Radscheibe 1 durch Schrauben 3 befestigte Blechringe 5, von welchen in axialer Richtung als Ventilationsflügel dienende Blechrippen 7 ausgehen. Die äußeren Enden der Blechrippen 7 sind an Reibringen 9 befestigt. Die Radscheibe 1 geht radial außerhalb der Blechringe 5 in eine Felge 11 über, auf welche ein Radreifen 13 aufgeschrumpft ist. Die Seitenflanken 14 des Radreifens 13 und der Felge 11 liegen in einer Ebene, in welcher zumindest annähernd auch die äußeren Radialflächen 15 der Reibringe 9 liegen. Den Radialflächen 14 und 15 sind voneinander getrennte Bremsbacken 17 und 19 bzw. 17 und 21 zugeordnet. Die in der Zeichnung der linken Radialfläche 15 zugeordnete Bremsbacke 19 sowie die Bremsbacken 17 sind mittels senkrecht zur Radachse angeordneter Bolzen 23 mit Trägern 25 bzw. 27 gelenkig verbunden. Die der rechten Radialfläche 15 zugeordnete Bremsbacke 21 ist dagegen starr am Träger 27 befestigt. Zwischen den Bremsbacken 17 und 19 bzw. 17 und 21 sind die Träger 25 bzw. 27 mit Bohrungen 29 versehen, mittels welcher sie an einem nur teilweise dargestellten Bremsgestänge 31 üblicher Art angelenkt sind.The wheel of a small-wheeled rail vehicle carries on its wheel disc 1 fastened by screws 3 sheet metal rings 5, of which in the axial direction as Ventilation blades serving sheet metal ribs 7 go out. The outer ends of the sheet metal ribs 7 are attached to friction rings 9. The wheel disc 1 goes radially outside the sheet metal rings 5 into a rim 11 onto which a wheel tire 13 is shrunk. The side flanks 14 of the wheel tire 13 and the rim 11 lie in a plane in which at least the outer radial surfaces 15 of the friction rings 9 are also approximately located. The radial surfaces 14 and 15 are assigned to separate brake shoes 17 and 19 and 17 and 21, respectively. The brake shoe 19 and assigned to the left radial surface 15 in the drawing the brake shoes 17 are connected by means of bolts 23 arranged perpendicular to the wheel axis Supports 25 and 27 are articulated. The one assigned to the right radial surface 15 In contrast, brake shoe 21 is rigidly attached to carrier 27. Between the brake shoes 17 and 19 or 17 and 21, the carrier 25 and 27 are provided with bores 29, by means of which they are articulated to a brake linkage 31 of the usual type, which is only partially shown are.

Die Bremsbacken 17, 19 und 21 weisen trotz großer, vorhandener Reibfläche eine nur geringe Breite auf, über welche sie durch die Träger 25 bzw. 27 eingeleiteten Druckkräfte ohne Schwierigkeiten verteilen können. Infolge der gegenseitigen Verschwenkbarkeit der Bremsbacken 17 und 19 bzw. 21 können sich diese leichten Abweichungen der Radialflächen 14 und 15 von den Sollagen anpassen, ohne die Verteilung der Druckkräfte wesentlich zu verändern. Dabei vermag die links dargestellte, teuere Anordnung, bei welcher beide Bremsbacken 17 und 19 schwenkbar am Träger 25 angelenkt sind, noch besser den Abweichungen der Radialflächen 14 und 15 von ihren Sollagen zu folgen als die billigere, rechts dargestellte Anordnung, bei welcher die Bremsbacke 21 starr am Träger 27 befestigt ist und daher eventuell verkantet an die Radialfläche 15 angepreßt wird.The brake shoes 17, 19 and 21 have a large, existing friction surface only a small width over which they were introduced through the carrier 25 and 27, respectively Can distribute pressure forces without difficulty. As a result of the mutual pivotability the brake shoes 17 and 19 or 21 can have these slight deviations in the radial surfaces 14 and 15 adjust from the target positions without significantly affecting the distribution of the pressure forces to change. The expensive arrangement shown on the left is capable of which both brake shoes 17 and 19 are pivotably articulated on the carrier 25, even better to follow the deviations of the radial surfaces 14 and 15 from their nominal positions than the cheaper arrangement shown on the right, in which the brake shoe 21 rigidly on Carrier 27 is attached and therefore possibly pressed against radial surface 15 at an angle will.

Durch die Wahl der Lage der Anlenkpunkte 29 des Bremsgestänges 31 an den Trägern 25 und 27 läßt sich eine günstige, auf die Aufnahmefähigkeit abgestimmte Verteilung der Bremsarbeit auf die Bremsbacken 17 und 19 bzw. 21 erzielen.By choosing the position of the articulation points 29 of the brake linkage 31 on the carriers 25 and 27 can be a favorable, adapted to the capacity Achieve distribution of the braking work on the brake shoes 17 and 19 or 21.

Ein weiterer Vorteil der erfindungsgemäßen Scheibenbremse ist darin zu erblicken, daß die durch die Blechrippen 7 geförderte Kühlluft durch die Bremsbacken 17, 19 und 21 ungehindert durch den Spalt zwischen dem Außenumfang der Reibringe 9 und dem Innenzylinder der Felge 11 ins Freie austreten kann.Another advantage of the disc brake according to the invention is therein to see that the cooling air conveyed through the sheet metal ribs 7 through the brake shoes 17, 19 and 21 unhindered by the gap between the outer circumference of the friction rings 9 and the inner cylinder of the rim 11 can escape into the open.
