Abstract

The brake fitting process is for a single-axle running gear of which the frame (2) is connected elastically by link rods (1) to the car body (5) of the rail vehicle. The rail brake (3) is guided in a direction opposite to the tipping motion of the frame into a position as near as possible parallel to the top edge of the rail. The rail brake may be attached to the car body by a control lever (4) and two other levers (6,7). The levers turn the brake about the turning link (8) on the axle bearing casing.

Description

Die Erfindung betrifft die Anordnung einer Magnetschienenbremse an einem Einzelachsfahrwerk, dessen Fahrwerkrahmen über Lenkerstangen elastisch mit einem Wagenkasten eines Schienenfahrzeuges verbunden ist.The invention relates to the arrangement of a magnetic rail brake on a single-axle running gear, the running gear frame of which is elastically connected to a car body of a rail vehicle via handlebar rods.

Bei Einzelachsfahrwerken können aufgrund der Elastizitäten der Lenkerstangen, vor allem beim Anfahren und Bremsen, Bewegungen des Fahrwerkrahmens auftreten. Dabei sind unerwünschte Berührungen zwischen einer in Tiefaufhängung angebrachten Magnetschienenbremse und der Schienenoberkante nicht auszuschließen.With single-axle chassis, movements of the chassis frame can occur due to the elasticity of the handlebars, especially when starting and braking. Unwanted contact between a magnetic rail brake mounted in the low suspension and the top edge of the rail cannot be ruled out.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine Magnetschienenbremse an einem Einzelachsfahrwerk derart anzuordnen, daß die zuvor genannten unerwünschten Berührungen sicher vermieden werden.The invention is accordingly based on the object of arranging a magnetic rail brake on a single-axle running gear in such a way that the aforementioned undesired contacts are reliably avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schienenbremse gegenläufig zu auftretenden Kippbewegungen des Fahrwerkrahmens in soweit wie möglich parallele Stellungen in bezug auf die Schienenoberkante gesteuert wird.This object is achieved in that the rail brake is controlled in opposite directions to occurring tilting movements of the chassis frame in as far as possible parallel positions with respect to the top edge of the rail.

Nach einer bevorzugten Ausführungsform der Erfindung ist die Schienenbremse durch Steuerungshebel am Wagenkasten angeschlossen.According to a preferred embodiment of the invention, the rail brake is connected to the car body by control levers.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und im folgenden näher beschrieben.An embodiment of the invention is shown schematically in the drawing and described in more detail below.

Der Fahrwerkrahmen 2 eines Einzelachsfahrwerks ist über Lenkerstangen 1 elastisch mit einem Wagenkasten 5 in den in Zeichnungsebene linken Festpunkten verbunden. Der Fahrwerkrahmen 2 kann den Elastizitäten der Lenkerstangen 1 entsprechende Kippbewegungen nach vorne oder hinten ausführen, wobei eine mögliche gekippte Stellung gestrichelt eingezeichnet ist.The undercarriage frame 2 of a single-axle undercarriage is connected elastically via handlebar rods 1 to a car body 5 in the fixed points on the left in the plane of the drawing. The undercarriage frame 2 can carry out tilting movements forwards or backwards corresponding to the elasticities of the handlebars 1, a possible tilted position being shown in dashed lines.

Eine Magnetschienenbremse 3 ist über ein Drehgelenk 8 an einem Achslagergehäuse 9 befestigt, das gegenüber dem Fahrwerkrahmen 2 nicht kippen kann. An dem vom Drehgelenk 8 abgewandten Ende der Schienenbremse 3 greift ein Steuerungshebel 7 an, der mit einem rahmenseitig gelagerten weiteren Hebel 6 verbunden ist. Dieser Hebel 6 ist über einen dritten Steuerungshebel 4 mit dem Wagenkasten 5 gekuppelt.A magnetic rail brake 3 is fastened via a swivel joint 8 to an axle bearing housing 9 which cannot tilt relative to the chassis frame 2. At the end of the rail brake 3 facing away from the pivot joint 8, a control lever 7 engages, which is connected to a further lever 6 mounted on the frame side. This lever 6 is coupled to the car body 5 via a third control lever 4.

Mit Hilfe der vorbeschriebenen Steuerungshebel wird die Schienenbremse 3 um das Drehgelenk 8 am Achslagergehäuse 9 geschwenkt, wobei das Übersetzungsverhältnis der Gelenkkette derart ausgestaltet ist, daß die Schienenbremse 3 im Bereich der technisch vorkommenden Kippbewegungen des Fahrwerkrahmens 2 parallele Stellungen zur Schienenoberkante SO einnimmt. Die in der Zeichnung lediglich der Übersicht halber dargestellte, zur Schienenoberkante SO hin geneigte Position der Schienenbremse 3 kann also nicht vorkommen.With the help of the control lever described above, the rail brake 3 is pivoted about the swivel joint 8 on the axle bearing housing 9, the transmission ratio of the articulated chain being designed such that the rail brake 3 assumes parallel positions to the upper rail edge SO in the region of the technically occurring tilting movements of the undercarriage frame 2. The position of the rail brake 3, which is shown in the drawing only for the sake of clarity and inclined toward the top edge SO of the rail, cannot therefore occur.

Der Steuerungshebel 4 sollte möglichst lang ausgeführt werden, um den Einfluß der vertikalen Einfederung des Wagenkastens 5 gegenüber dem Fahrwerkrahmen 2 auf die gewollten parallelen Stellungen der Schienenbremse 3 gering zu halten.The control lever 4 should be made as long as possible in order to keep the influence of the vertical deflection of the car body 5 relative to the chassis frame 2 on the desired parallel positions of the rail brake 3 low.
