Abstract

The brake magnet holder (3) includes a part (4) for transmitting cross-direction forces from the brake magnet (1) into an axle bearing casing (6). The brake is suspended from the bogie (5) of a rail vehicle by securing each end of the brake magnet to a holder connected to an axle bearing casing. A stop (7) is provided between the magnet and bogie for transmitting length direction forces when the magnet is in the working position.

Description

Die Erfindung betrifft die Aufhängung einer Magnetschienenbremse an einem Fahrgestell eines Schienenfahrzeuges, deren Bremsmagnet im Bereich seiner Längsenden jeweils an einer mit einem Radsatzlagergehäuse verbundenen Halterung befestigt und über Federn in seiner Ruhestellung fixiert ist, wobei zwischen dem Bremsmagneten und dem Rahmen des Fahrgestelles ein Anschlag zur Übertragung der in Wirkstellung des Bremsmagneten auftretenden Längskräfte angeordnet ist.The invention relates to the suspension of a Magnetic rail brake on a chassis of a Rail vehicle whose brake magnet is in the area of its Longitudinal ends each on one with a wheelset bearing housing connected bracket attached and via springs in its Rest position is fixed, being between the brake magnet and the frame of the chassis a stop for transmission the occurring in the operative position of the brake magnet Longitudinal forces is arranged.

Eine Aufhängung mit den zuvor genannten Merkmalen wurde bei Schienenfahrzeugen vielfach realisiert, wobei dafür auch die Bezeichnung "Magnetschienenbremse mit Tiefaufhängung" geläufig ist. Der Nachteil dieser an sich bewährten Aufhängung liegt darin, dass bei einigen Bauweisen der Bremsmagnet in Fahrzeugquerrichtung nicht geführt und oder bei anderen Bauweisen der Bremsmagnet in Querrichtung gegenüber dem federnd auf den Rädern gelagerten Rahmen des Fahrgestelles geführt ist. Bei beiden Bauweisen können Querbewegungen des Bremsmagneten auftreten, die im betrieblichen Einsatz Probleme bereiten und im Extremfall bis zu einem Abreißen des abgesenkten Bremsmagneten bei dem Befahren von Weichen reichen.A suspension with the above-mentioned features was added Rail vehicles have been implemented in many cases, including the Designation "magnetic rail brake with low suspension" is common. The disadvantage of this proven in itself Suspension is that with some designs the Brake magnet not guided in the transverse direction of the vehicle and or in other designs, the brake magnet in the transverse direction compared to the frame of the Chassis is guided. With both designs Cross movements of the brake magnet occur in the operational problems and in extreme cases up to to tear off the lowered brake magnet in the Driving on switches is enough.

Der Erfindung liegt die Aufgabe zugrunde, eine Aufhängung der gattungsgemäßen Art durch einfache Mittel so auszubilden, dass über eine kontinuierliche Mitnahme des Bremsmagneten nur geringe Seitenkräfte und praktisch keine Bewegungen des Bremsmagneten in Querrichtung auftreten können.The invention has for its object a suspension of the Generate generic type by simple means so that about a continuous drive of the brake magnet only low lateral forces and practically no movements of the Brake magnets can occur in the transverse direction.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Halterung ein Element zur Übertragung von Querkräften zwischen dem Bremsmagneten und dem Radsatzlagergehäuse aufweist.This object is achieved in that the Bracket an element for the transmission of lateral forces between the brake magnet and the wheelset bearing housing having.

Nach einer baulich besonders einfachen Ausgestaltungen der Erfindung ist das Element zur Übertragung von Querkräften durch zwei Stege gebildet.After a structurally particularly simple configurations of the Invention is the element for the transmission of lateral forces formed by two webs.

Gemäß einer nächsten Ausführungsform der Erfindung ist vorgesehen, dass zwischen den Stegen des Elements zur Übertragung von Querkräften und dem Bremsmagneten jeweils ein derart definiertes Querspiel besteht, dass der Bremsmagnet in Querrichtung zwar begrenzt pendeln kann, der sogenannte Radschatten im Spurkanal jedoch nicht überschritten wird.According to a next embodiment of the invention provided that between the webs of the element for Transfer of lateral forces and the brake magnet each one Cross-clearance defined in such a way that the brake magnet in Transverse direction can swing limited, the so-called Wheel shadows in the track channel are not exceeded.

Im weiteren wird die Erfindung anhand eines Ausführungsbeispiels näher beschrieben, das in der Zeichnung prinzipartig dargestellt ist. Es zeigen

Ein Bremsmagnet 1 einer Magnetschienenbremse ist im Bereich seiner Längsenden jeweils an einer Halterung 3 befestigt, die mit einem Radsatzlagergehäuse 6 verbunden ist. Zur Fixierung des Bremsmagneten 1 in der gezeigten Ruhestellung sind Federn 2 vorgesehen. Zwischen den Halterungen 3 und dem Rahmen 5 des Fahrgestelles sind Anschläge 7 angeordnet, die in Wirkstellung des Bremsmagneten 1 auftretende Längskräfte nach Wegfall eines Längsspieles - siehe Maß x in Fig. 1 - unmittelbar auf den Rahmen 7 übertragen. Die Radsatzlagergehäuse 6 werden also nicht mit solchen Längskräften beaufschlagt.A brake magnet 1 of a magnetic rail brake is in the area its longitudinal ends each attached to a bracket 3, the is connected to a wheelset bearing housing 6. For fixation of the brake magnet 1 in the rest position shown are springs 2 provided. Between the brackets 3 and the frame 5 of the Chassis stops 7 are arranged in Active position of the brake magnet 1 occurring longitudinal forces Elimination of longitudinal play - see dimension x in Fig. 1 - transferred directly to the frame 7. The Wheelset bearing housing 6 are not with such Longitudinal forces applied.

Zusätzlich weisen die Halterungen 3 jeweils ein Element 4 zur Übertragung von Querkräften zwischen dem Bremsmagneten 1 und dem Radsatzlagergehäuse auf. Durch diese Elemente 4, die im Ausführungsbeispiel jeweils durch zwei Stege gebildet sind, wird eine kontinuierliche Mitnahme des Bremsmagneten 1 erzielt, durch die keine größeren Bewegungen des Bremsmagneten 1 in Querrichtung auftreten können. Jedoch besteht zwischen den Stegen des Elements 4 und dem Bremsmagneten ein Querspiel in der Größenordnung der Maß a in Fig. 2. Dieses Querspiel ist so definiert, dass der Bremsmagnet 1 in Querrichtung zwar begrenzt pendeln kann, der sogenannte Radschatten (Maß b) im Spurkanal jedoch nicht überschritten wird.In addition, the brackets 3 each have an element 4 Transfer of lateral forces between the brake magnet 1 and the wheelset bearing housing. Through these elements 4, which in Embodiment are each formed by two webs, is a continuous entrainment of the brake magnet 1st achieved by which no major movements of the Brake magnet 1 can occur in the transverse direction. however exists between the webs of element 4 and the Brake magnets a cross game in the order of the dimension a in Fig. 2. This cross game is defined so that the Brake magnet 1 can oscillate to a limited extent in the transverse direction However, so-called wheel shadows (dimension b) in the track channel are not is exceeded.
