Abstract

Rail vehicles have a brake linkage being acted on by a brake cylinder for acting on at least one wheel set of a bogie, truck or running gear of the rail vehicle through brake blocks having brake block shoes and brake block shoe inserts. A block brake for rail vehicles should be economical and be constructed in such a way that higher braking capacities can be achieved, that damage to the tires of the wheels of the wheel set is avoided and that wheel noise of the wheel sets is minimized. The block brake includes at least one rotationally symmetrical brake body being fixedly disposed on a wheel set shaft of the wheel set between the wheel discs of the wheel set. The acted-on brake block rests on an outer surface of the brake body.

Description

Die Erfindung betrifft eine Klotzbremse für Schienenfahrzeuge, entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a block brake for rail vehicles, according to the preamble of claim 1.

Bekannt sind aus der Praxis Klotzbremsen für Schienenfahrzeuge, insbesondere im Bereich des Güterverkehrs, über die bis zu einer max. zulässigen Geschwindigkeit von 120 km/h die gesamte Abbremsung des Schienenfahrzeugs erfolgt. Bei diesen bekannten Klotzbremsen wirken die aus Bremsklotzschuhen und Bremskklotzsohlen bestehenden Bremsklötze direkt auf die Lauffläche des Radreifens des Radsatzes. Die Bremsklötze sind an einer Bremstraverse aufgehängt. Die Bremsklotzschuhe mit der Bremstraverse sind gelenkig im Schienenfahrzeug oder im Fahrwerk des Schienenfahrzeugs an dessen Rahmen gelagert und werden von einem Bremszylinder über eine Bremszugstange unter Zwischenschaltung des Mittenbremsgestänges und eventuellen Verbindungshebeln zwischen den Bremstraversen beaufschlagt.Block brakes for rail vehicles are known from practice, particularly in the field of freight transport, via which up to a max. permissible speed of 120 km / h the entire braking of the rail vehicle takes place. In these known block brakes, the brake blocks consisting of brake block shoes and brake block soles act directly on the tread of the wheel tire of the wheel set. The brake pads are suspended on a brake crossbar. The brake block shoes with the brake crossmember are articulated in the rail vehicle or in the chassis of the rail vehicle on its frame and are acted upon by a brake cylinder via a brake pull rod with the interposition of the center brake linkage and any connecting levers between the brake crossbars.

Diese vorstehend beschriebene Klotzbremse erfüllt ihre Aufgabe bis zu der genannten Geschwindigkeit bei den im Güterverkehr üblichen Lasten bis zu 22,5 t pro Achse zufriedenstellend und besteht aus einfachen, wirtschaftlich herzustellenden und mit geringem Aufwand zu wartenden Bauteilen. Als Nachteil hat sich jedoch herausgestellt, daß die beim Abbremsen entstehende Bremswärme zu Beschädigungen des Radreifens und der Lauffläche führt.This block brake described above fulfills its task up to the above-mentioned speed satisfactorily with the loads of up to 22.5 t per axle which are common in freight transport and consists of simple, economically manageable components which can be maintained with little effort. A disadvantage has been found, however, that the braking heat generated during braking leads to damage to the wheel tire and the tread.

Folge hiervon ist eine rauhe und wellige Lauffläche u. U. sogar Rißbildung in der Lauffläche. Durch die mechanische Einwirkung der Bremsklötze auf die Lauffläche entsteht zudem eine Riffelbildung auf der Lauffläche. Durch diese Veränderungen der Lauffläche des Radreifens ensteht ein sehr hohes Abrollgeräusch. Bei Beschädigung des Radreifens durch Rißbildung muß der Radsatz ausgetauscht werden. Eine Klotzbremse der eingangs genannten Art ist aus der US-A-2169751 bekannt, bei welcher ein Bremszylinder über eine Traverse ein Bremsgestänge beaufschlagt, das seinerseits mit Bremsklötzen verbunden ist, die beiderseits radial auf den Mantelflächen von auf der Radsatzwelle zwischen den Radscheiben angeordneten rotationssymmetrischen Bremskörpern aufliegen.The consequence of this is a rough and wavy tread u. U. Even cracking in the tread. The mechanical action of the brake pads on the tread also creates corrugations on the tread. These changes in the tread of the wheel tire result in a very high rolling noise. At Damage to the wheel tire due to crack formation, the wheel set must be replaced. A block brake of the type mentioned is known from US-A-2169751, in which a brake cylinder acts on a crossbar on a brake linkage, which in turn is connected to brake blocks, which are on both sides radially on the lateral surfaces of the rotationally symmetrical brake bodies arranged on the wheel set shaft between the wheel disks lie on.

Die Traverse ist als gerader Hebel ausgebildet, bei welchem abhängig von Reibung und Maßabweichungen eine schiefe Belastung des eingeschlossenen Bremsgestänges möglich ist. Dies gilt es generell zu vermeiden.The traverse is designed as a straight lever, with which, depending on friction and dimensional deviations, an inclined loading of the enclosed brake linkage is possible. This should generally be avoided.

Ausgehend von diesem Stand der Technik hat die vorliegende Erfindung die Aufgabe, eine Klotzbremse zu schaffen, bei der eine möglichst gleichmäßige Aufbringung der Bremskraft erfolgt. Dies wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 erreicht. Durch diese Ausgestaltung gemäß der Erfindung wird die Radachse frei von Zusatzlängskräften gehalten, so daß sich auch beim Bremsvorgang der Radsatz weitestgehend dem Gleisverlauf entsprechend einstellen kann.Starting from this prior art, the present invention has the task of creating a block brake in which the braking force is applied as uniformly as possible. This is achieved by the features of the characterizing part of claim 1. By means of this embodiment according to the invention, the wheel axle is kept free of additional longitudinal forces, so that the wheel set can largely adjust itself to the course of the track even when braking.

Gemäß der Erfindung sind die Bremsklotzschuhe an Bremsklotzhängeeisen aufgehängt und an einer Bremstraverse gelagert. Gemäß der Erfindung ist weiter bei Anordnung von zwei Bremskörpern auf der Radsatzwelle die Bremstraverse als Bremsdreieck ausgebildet. Durch diese erfindungsgemäße Anordnung und Ausbildung der Bremsteile wird eine weitestgehende Annäherung an die gebräuchlichen Klotzbremsen erzielt und damit eine einfache und wirtschaftliche Ausbildung der erfindungsgemäßen Klotzbremse gewährleistet.According to the invention, the brake block shoes are suspended from brake block hangers and are mounted on a brake crossmember. According to the invention, the brake crossmember is further configured as a brake triangle when two brake bodies are arranged on the wheelset shaft. As a result of this arrangement and design of the brake parts according to the invention, the most common approach to the conventional block brakes is achieved, thus ensuring a simple and economical design of the block brake according to the invention.

Jeder Bremsklotz kann gemäß einem Ausführungsbeispiel der Erfindung auf dem Bremskörper axial geführt sein. Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist die Bremstraverse am Rahmen des Fahrwerks oder des Untergestells des Schienenfahrzeugs seitlich geführt. Durch diese Maßnahmen ist die seitliche Führung der Bremsklötze und damit die Betriebssicherheit gewährleistet.According to one embodiment of the invention, each brake pad can be guided axially on the brake body. According to a further exemplary embodiment of the invention, the brake crossmember is guided laterally on the frame of the chassis or the underframe of the rail vehicle. Through these measures, the side Guidance of the brake pads and thus the operational safety guaranteed.

Einzelheiten der Erfindung sind anhand eines Ausführungsbeispiels in der Zeichnung erläutert.Details of the invention are explained using an exemplary embodiment in the drawing.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel der Erfindung ist diese an dem Laufwerk eines 2achsigen Eisenbahngüterwagens dargestellt. Der im wesentlichen aus der Radsatzwelle (2) mit den Radscheiben (3) bestehende Radsatz (1) ist dabei, wie aus der Praxis bekannt, über äußere Achslager (4) und nicht dargestellte Blatttragfedern unter Zwischenschaltung von ebenfalls nicht dargestellten Schakengehängen an Federböcken (5) des Untergestells (6) des Eisenbahngüterwagens aufgehängt. Zwischen den Radscheiben (3) des Radsatzes (1) ist auf der Radsatzwelle (2) beidseitig der Mittellängsachse des Eisenbahngüterwagens je ein rotationssymmetrischer Bremskörper (7) drehfest angeordnet. Der rotationssymmetrische Bremskörper (7) weist dabei eine zylindrische Mantelfläche (8) und einen über die Mantelfläche (8) hinausragenden Spurkranz (9) auf.In the embodiment of the invention shown in the drawing, this is shown on the carriage of a 2-axle rail freight wagon. The wheel set (1), which essentially consists of the wheel set shaft (2) with the wheel disks (3), is, as is known from practice, via external axle bearings (4) and leaf suspension springs (not shown) with the interposition of shackle hangers (also not shown) on spring brackets (5 ) of the base (6) of the rail freight wagon. Between the wheel disks (3) of the wheelset (1), a rotationally symmetrical brake body (7) is arranged on the wheelset shaft (2) on both sides of the central longitudinal axis of the rail freight wagon. The rotationally symmetrical brake body (7) has a cylindrical outer surface (8) and a flange (9) projecting beyond the outer surface (8).

In dem Untergestell (6) des Eisenbahngüterwagens ist über Bremklotzhängeeisen (10) beidseitig des Radsatzes (1) je eine Bremstraverse (11) gelenkig aufgehängt. Die Bremstraverse (11) trägt an ihren beiden Längsenden je einen aus Bremsklotzsohle (12) und Bremsklotzschuh (13) bestehenden Bremsklotz (14). Die Bremsklotzsohlen (12) jeden Bremklotzschuhs (13) liegen vor der Mantelfläche (8) des Bremskörpers (7).In the base frame (6) of the rail freight wagon, a brake cross member (11) is articulated on both sides of the wheel set (1) via brake block hangers (10). The brake crossmember (11) carries a brake block (14) consisting of a brake block sole (12) and a brake block shoe (13) at each of its two longitudinal ends. The brake block soles (12) of each brake block shoe (13) lie in front of the outer surface (8) of the brake body (7).

Mittig ist jede Bremstraverse (11) gelenkig an einem Bremshebel (15) befestigt, wobei ein Bremshebel (15) mit seinem nach oben ragenden Ende gelenkig an einem Festpunktlager (16) des Untergestells (6) des Eisenbahngüterwagens gelagert ist. Der zweite Bremshebel (15) trägt an seinem oberen freien Ende (mit A gekennzeichnet) eine nicht dargestellte Bremszugstange. Mittig sind beide Bremshebel (15) gelenkig durch einen Bremshebelverbinder (17) miteinander verbunden. Der die Bremszugstange tragende Bremshebel (15) ist weiter über sein den Bremshebelverbinder (17) tragendes Gelenk (18) mit einem Bremshängeeisen (19) gelenkig verbunden, daß ebenfalls gelenkig am Untergestell (6) des Eisenbahngüterwagens befestigt ist.Each brake crossmember (11) is articulated in the center on a brake lever (15), a brake lever (15) with its upwardly projecting end being articulated on a fixed point bearing (16) of the underframe (6) of the rail freight wagon. The second brake lever (15) carries at its upper free end (marked A) a brake cable, not shown. In the center, both brake levers (15) are articulated to one another by a brake lever connector (17). The brake lever (15) carrying the brake cable rod is further articulated via its articulation (18) carrying the brake lever connector (17) to a brake hanger (19), which is also articulated to the base frame (6) of the rail freight wagon.

Über die nicht dargestellte Bremszugstange und ein ebenfalls nicht dargestelltes, jedoch aus der Praxis bekanntes Mittenbremsgestänge wird der Radsatz (1) mittels eines Bremszylinders dadurch abgebremst, daß die Bremsklötze (14) über die Bremsklotzsohlen (12) gegen die Mantelfläche (8) des Bremskörpers (7) gedrückt werden.The wheel set (1) is braked by means of a brake cylinder by means of the brake cable rod (not shown) and a center brake linkage (also not known from practice) in that the brake blocks (14) via the brake block soles (12) against the lateral surface (8) of the brake body ( 7) can be pressed.

Gemäß der Erfindung ist weiter denkbar, anstelle des einen Spurkranzes (9) des Bremskörpers (7) auf jeder Längsseite des Bremskörpers (7) einen Spurkranz anzuordnen oder die Mantelfläche (8) des Bremskörpers (7) mit einer den Bremsklotz (14) seitlich führenden Kontur, beispielsweise konvex oder konkav, zu versehen. Es ist auch weiter denkbar, zur seitlichen Führung der Bremstraverse (11) diese selbst durch seitliche Führungen (20) im Untergestell des Eisenbahngüterwagens zu führen.According to the invention, it is further conceivable to arrange a wheel flange on each longitudinal side of the brake body (7) instead of the one wheel flange (9) of the brake body (7) or the lateral surface (8) of the brake body (7) with a brake block (14) leading laterally Contour, for example convex or concave. It is also conceivable for the lateral guidance of the brake crossmember (11) to be guided by lateral guides (20) in the base of the rail freight wagon.

Grundsätzlich kann bei der erfindungsgemäßen Klotzbremse die Führung der Bremsklötze (14) auf den Bremkörper (7) zum einen auf die Art erfolgen, daß die erforderlichen Querbewegungen des Radsatzes (1) relativ zur Bremstraverse (11) und damit zum Bremsklotz (14) erfolgen und zum anderen auf die Weise, daß die Querbewegungen des Radsatzes (1) auf die Bremstraverse (11) und damit auf die Bremsklötze (14) übertragen werden und daß aus Bremsklötzen und Bremstraverse bestehende Achsbremsgestänge bei diesen Querbewegungen mitpendelt.In principle, in the block brake according to the invention, the brake blocks (14) can be guided onto the brake body (7) in such a way that the required transverse movements of the wheel set (1) take place relative to the brake crossmember (11) and thus to the brake block (14) and on the other hand in such a way that the transverse movements of the wheelset (1) are transmitted to the brake crossmember (11) and thus to the brake pads (14) and that existing brake rod linkage composed of brake pads and brake crossmember oscillates with these transverse movements.
