Definitions
- the invention relates to an arrangement for the movable suspension of block brake units for steering axles or radially adjustable wheel sets of rail vehicles on the vehicle or bogie frame and for their support in the longitudinal direction of the frame.
- the invention has for its object to provide an arrangement of the type mentioned, which ensures a constant brake pad play with simple and inexpensive construction and reliable operation and ensures that the brake pad holder of the pad brake unit is always aligned parallel to the tread of the associated wheel and the wheel also remains steerable when braked.
- the block brake unit 1 is assigned to a wheel 2 of a rail vehicle, which rolls on a rail 3, has a wheel flange 4 and belongs to a wheel set which is arranged in a bogie frame 5 such that it moves into a radial position with respect to the same when passing through a track curve can.
- the block brake unit 1 interacts with the wheel 2 by means of a brake block holder 8 provided with brake blocks 6, 7 and has a brake cylinder, a transmission gear and a stroke actuator for actuating the brake block holder 8, which can function as shown in DE 41 17 632 A1 and described, and which are housed in a housing 9.
- the brake pad holder 8 is suspended using a hanging bracket 10 and a parallel link 11, as suggested in patent application P 42 35 310.6 dated October 20, 1992.
- the block brake unit 1 is pivotally connected to the bogie frame 5 at the upper end 12 about an axis 14 which is substantially parallel to the axis 13 of the wheel 2. Furthermore, it is connected to the outer axle bearing housing 16 adjacent to the wheel 2 approximately at the level of the wheel axle 13 by means of a lateral coupling rod 15 which runs essentially perpendicular to the wheel axle 13.
- the block brake unit 1 is provided on the side facing away from the wheel flange 4 of the wheel 2 with a protruding pin 17 on which the adjacent end 18 of the coupling rod 15 is supported in the manner of a ball joint.
- the other end 19 of the coupling rod 15 is articulated to the outer axle bearing housing 16.
- the hanging bracket 10 is pivotally connected to the bogie frame 5 at the upper end 20 facing away from the brake block holder 8 about the same axis 14 as the block brake unit 1.
- the parallel link 11 is at the upper end 21 facing away from the brake block holder 8 about a common pivot axis 14 of the block brake unit 1 and the hanging bracket 10 parallel axis 22 pivotally connected to the bogie frame 5.
- the block brake unit 1, the hanging bracket 10 and the parallel link 11 are pivotally mounted on a bracket 23 which is fastened to the bogie frame 5 by means of screws 24.
Description
Die Erfingung bezieht sich auf eine Anordnung zur beweglichen Aufhängung von Klotzbremseinheiten für Lenkachsen oder im Gleisbogen radial einstellbare Radsätze von Schienenfahrzeugen am Fahrzeug- oder Drehgestellrahmen und zu deren Abstützung in Rahmenlängsrichtung.The invention relates to an arrangement for the movable suspension of block brake units for steering axles or radially adjustable wheel sets of rail vehicles on the vehicle or bogie frame and for their support in the longitudinal direction of the frame.
Es ist bekannt, die Klotzbremseinheiten für quer bewegliche Radsätze von Schienenfahrzeugen mit dem oberen Ende am Fahrzeug- oder Drehgestellrahmen auf einer Stange seitlich verschiebbar zu lagern, welche sich in Rahmenquerrichtung bzw. parallel zur Radsatzachse erstreckt, und am unteren Ende durch eine in Rahmenlängsrichtung verlaufende Zugstange mit dem Fahrzeug-oder Drehgestellrahmen oder dann, wenn das zugehörige Rad zweiseitig gebremst wird und auf der der Klotzbremseinheit abgewandten Radseite ein Bremsklotzgehänge vorgesehen ist, mit dessen unterem Ende zu verbinden. Auf diese Weise können die Klotzbremseinheiten allen seitlichen Bewegungen des zugehörigen Rades folgen (DE 34 09 158 A1, Fig. 4).It is known to mount the block brake units for transversely movable wheel sets of rail vehicles with the upper end on the vehicle or bogie frame laterally displaceably on a rod which extends in the transverse direction of the frame or parallel to the axle of the wheel set, and at the lower end by a pull rod running in the longitudinal direction of the frame with the vehicle or bogie frame or when the associated wheel is braked on both sides and on the wheel side facing away from the block brake unit a brake block hanger is provided with its lower end. In this way, the block brake units can follow all lateral movements of the associated wheel (DE 34 09 158 A1, Fig. 4).
Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung der eingangs angegebenen Art zu schaffen, welche bei einfachem und kostengünstigem Aufbau sowie zuverlässiger Funktionsweise ein konstantes Bremsklotzspiel gewährleistet und sicherstellt, daß der Bremsklotzhalter der Klotzbremseinheit stets parallel zur Lauffläche des zugehörigen Rades ausgerichtet ist und das Rad auch in gebremstem Zustand lenkbar bleibt.The invention has for its object to provide an arrangement of the type mentioned, which ensures a constant brake pad play with simple and inexpensive construction and reliable operation and ensures that the brake pad holder of the pad brake unit is always aligned parallel to the tread of the associated wheel and the wheel also remains steerable when braked.
Diese Aufgabe ist durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Anordnung sind in den restlichen Patentansprüchen angegeben.This object is achieved by the features specified in the characterizing part of
Nachstehend ist eine Ausführungsform der erfindungsgemäßen Anordnung anhand von Zeichnungen beispielsweise beschrieben. Darin zeigt:
- Fig. 1
- die Seitenansicht in Richtung des Pfeils I in Fig. 2; und
- Fig. 2
- die teilweise geschnittene Ansicht in Richtung des Pfeils II in Fig. 1 in anderem Maßstab.

- the side view in the direction of arrow I in Fig. 2; and
- Fig. 2
- the partially sectioned view in the direction of arrow II in Fig. 1 on a different scale.
Die Klotzbremseinheit 1 ist einem Rad 2 eines Schienenfahrzeugs zugeordnet, welches auf einer Schiene 3 rollt, einen Spurkranz 4 aufweist und zu einem Radsatz gehört, der in einem Drehgestellrahmen 5 so angeordnet ist, daß er sich beim Durchfahren eines Gleisbogens in eine Radialstellung bezüglich desselben bewegen kann.The
Die Klotzbremseinheit 1 wirkt mittels eines mit Bremsklötzen 6, 7 versehenen Bremsklotzhalters 8 mit dem Rad 2 zusammen und weist zur Betätigung des Bremsklotzhalters 8 einen Bremszylinder, ein Übersetzungsgetriebe und einen Hubsteller auf, welche so funktionieren können, wie in der DE 41 17 632 A1 dargestellt und geschildert, und welche in einem Gehäuse 9 untergebracht sind. Der Bremsklotzhalter 8 ist unter Verwendung einer Hängelasche 10 und eines Parallellenkers 11 pendelnd aufgehängt, wie in der Patentanmeldung P 42 35 310.6 vom 20. Oktober 1992 vorgeschlagen.The
Die Klotzbremseinheit 1 ist am oberen Ende 12 um eine zur Achse 13 des Rades 2 im wesentlichen parallele Achse 14 schwenkbar mit dem Drehgestellrahmen 5 verbunden. Weiterhin ist sie etwa in Höhe der Radachse 13 durch eine im wesentlichen senkrecht zur Radachse 13 verlaufende, seitliche Koppelstange 15 mit dem dem Rad 2 benachbarten Außenachslagergehäuse 16 verbunden.The
Wie besonders deutlich aus Fig. 2 hervorgeht, ist die Klotzbremseinheit 1 auf der dem Spurkranz 4 des Rades 2 abgewandten Seite mit einem abstehenden Zapfen 17 versehen, auf welchem das benachbarte Ende 18 der Koppelstange 15 kugelgelenkartig gelagert ist. Auf dieselbe oder ähnliche Weise ist das andere Ende 19 der Koppelstange 15 an das Außenachslagergehäuse 16 angelenkt.As can be seen particularly clearly from FIG. 2, the
Die Hängelasche 10 ist an dem dem Bremsklotzhalter 8 abgewandten oberen Ende 20 um dieselbe Achse 14 schwenkbar mit dem Drehgestellrahmen 5 verbunden, wie die Klotzbremseinheit 1. Der Parallellenker 11 ist an dem dem Bremsklotzhalter 8 abgewandten oberen Ende 21 um eine zur gemeinsamen Schwenkachse 14 der Klotzbremseinheit 1 und der Hängelasche 10 parallele Achse 22 schwenkbar mit dem Drehgestellrahmen 5 verbunden.The hanging
Die Klotzbremseinheit 1, die Hängelasche 10 und der Parallellenker 11 sind an einer Konsole 23 schwenkbar gelagert, welche am Drehgestellrahmen 5 mittels Schrauben 24 befestigt ist.The
