Description

Die Erfindung· betrifft eine Reibungsbremse, insbesondere für elektrisch, betriebene Gleisfahrzeuge, bei der die beweglichen Bremsteile, die die Gestalt vom doppelarrnigen Hebeln besitzen, auf <einem !gemeinsamen Gelenk angeordnet sind. Während je ein Hebelarm eines jeden Biremsteilss die Bremsbacken oder die Bremsbeläge trägt, bilden die anderen Hebelarme Angriffsflächen für die Bremsbetätigungsglieder, die beispielsweise, aus Knebeln, unrunden Scheiben usw. bestehen können. Die Knebel oder unrunden Scheiben wirken bei Verdrehung auf die Hebelverlängerungen ein und erzeugen dadurch den erforderlichen Bremsdruck.The invention relates to a friction brake, especially for electrically operated track vehicles, in which the movable Brake parts that take the shape of the double-twisted Have levers on <a! Common joint are arranged. While one lever arm each Each Biremteilss carries the brake shoes or the brake linings, form the others Lever arms engagement surfaces for the brake actuators, for example, from Toggles, non-round discs, etc. may exist. The toggles or non-round disks act when twisted on the lever extensions and thereby generate the required Brake pressure.

Die Angriffspunkte der Knebel an den Bremshebelverlängerungen liegen jedoch nicht in einer Entfernung von dem Hebeldrahgelenk, so daß sich bei seitlich unverriickbarer Lage der Bremsbacken und der Bremsscheiben infolge der ungleichen Hebellängen auch ungleiche Bremsdrücke ergeben, die den Wirkungsgrad der Brems einrichtung herabsetzen und eine einseitige Abnutzung dar Reibungsflächen zur Folge haben müssen. Ein Ausgleich könnte dadurch geschaffen werden, daß entweder die Bremsscheibe ader die Bremsbacken axial verschiebbar gelagert werden. Dies führt aber zu umständlichen und kostspieligen Anordnungen, außerdem können leicht Klemmungen auftreten.However, the points of application of the toggles on the brake lever extensions are not at a distance from the lever wire hinge so that the laterally immovable Position of the brake shoes and the brake disks as a result of the unequal lever lengths also result in unequal brake pressures that cause the Reduce the efficiency of the braking device and one-sided wear is the friction surfaces have to result. A compensation could be created that either the brake disc vein the brake shoes are axially displaceable. But this leads to cumbersome and expensive arrangements, and jamming can easily occur.

Nach der Erfindung wird dieser Nachteil dadurch beseitigt, daß die Lager der Bremsbacken im Verhältnis der Knebelhöhe bzw. der Entfernung der Angriffspunkte des Knebels an den Hebelverlängerungen gegeneinander versetzt werden. Es kann dies in der Weise geschehen, daß der gemeinsame Gelenkbolzem mit zwei exzentrisch zueinander liegenden Zapfen versehen wird.According to the invention, this disadvantage is eliminated in that the bearings of the brake shoes in the ratio of the toggle height or the distance of the points of application of the toggle be offset against each other on the lever extensions. This can be done in such a way that the common joint bolt is provided with two eccentric pins.

Die Zeichnung· stellt ein Ausfübrungsbeispiel dar. Es bedeuten bx und b2 die beiden Bremsbacken, die beiderseits auf die Bremsscheibe s einwirken. Der zum Anpressen der Bremsbacken an die Bremsscheibe dienende Knebel ist mit k bezeichnet. Der Bolzen zur Lagerung der Boremebackein besitzt zwei exzentrisch gegeneinander versetzte Teile tt und t2, welche beim dargestellten Beispiel um die halbe Höhe das Knebelst der Entfernung ζ so versetzt sind. Wird der Knebelt entgegen dem Uhrzeigiersinine .gedreht, .so wirken auf die rückseitigen Verlängerungen der Bremsbacken bx und b2 die Kräfte K% ^und K2 an den durch die Pfeile gekennzeichneten Stellen ein. Die Entfernung χ zwischen dem Punkte, an dem die Kraft Ki angreift und dem Drehpunkt £, ist gleich, groß der Entfernuing χ zwischen dem Drehpunkt^ und der Mitte der Bremsbacke bt. Desgleichen sind die mit y bezeichnetan Entfernungen zwischen dem Punkte K^ und dem Dtfehpunlkt t2 bzw. dem Drehpunkt t2 und der Mitte der Bremsbacke b2 einander gleich. Die an den Bremsbacken zur" Wirkung kommenden Kräfte sind nunmehr, wie sich aus den Beziehungen:The drawing represents an exemplary embodiment. B x and b 2 denote the two brake shoes which act on both sides of the brake disk s. The toggle used to press the brake shoes against the brake disc is denoted by k. The bolt for mounting the Boremebackein has two eccentrically offset parts t t and t 2 , which in the example shown are offset by half the height of the toggle of the distance ζ. If the toggle is turned counterclockwise, the forces K% ^ and K2 act on the rear extensions of the brake shoes b x and b 2 at the points indicated by the arrows. The distance χ between the point at which the force Ki acts and the fulcrum £ is the same, the distance χ between the fulcrum ^ and the center of the brake shoe b t is the same. Likewise, the distances denoted by y between the point K ^ and the Dtfehpunlkt t 2 or the pivot point t 2 and the center of the brake shoe b 2 are equal to each other. The forces coming into effect on the brake shoes are now, as can be seen from the relationships:

1 x y 1 xy

ergibt, 'einander gleich uiniüer Berücksichtigung der zulässigen Annahme, daß an den Knebelkanten gleiche Kräfte wirken. Es ist also K1 = K2 pad auch Bx = B2. In ähnlicher Weise Jäßt sich ein Ausgleich schaffen, wann an ,Stelle der beim Ausführungsbeispiel verwendeten Knebel k Kurvenscheiben o. dgl. benutzt warden.results, 'equal to each other, taking into account the permissible assumption that the same forces act on the toggle edges. So it is K 1 = K 2 pad also B x = B 2 . In a similar way, a compensation can be created when, instead of the toggle k used in the exemplary embodiment, cam disks or the like are used.
