Description
Scheibenbremse für Fahrzeuge Die Erfindung betrifft eine Scheibenbremse für Fahrzeuge, insbesondere für elektrisch betriebene Schienenfahrzeuge, bei der die Abstandsänderung der Bremsbacke zur Bremsscheibe über ein Sperrad durch ein Sölenoid einer Nachstelleinrichtung ausgeglichen wird.Disc brake for vehicles The invention relates to a disc brake for vehicles, in particular for electrically operated rail vehicles, in the the change in the distance between the brake shoe and the brake disc via a ratchet wheel Sölenoid an adjusting device is compensated.
Es sind bereits Scheibenbremsen bekannt, bei denen der Verschleiß der Bremsbeläge durch Verstellvorrichtungen ausgeglichen wird, die von Hand und bei haltendem Fahrzeug betätigt werden. -Da das Verstellen nur in größeren Zeitabständen vorgenommen werden kann, erfolgt mit dem fortschreitenden Verschleiß ein tieferes Eindringen der Zugstange in das Bremssolenoid, so daß sich eine stetig verändernde Bremskraft ergibt. Hierdurch treten bei leerem Wagen Überbremsungen ein, die zur Flachstellenbildung an den schleifenden Rädern führen.Disc brakes are already known in which the wear the brake pads is compensated by adjusting devices that are made by hand and be operated when the vehicle is stationary. -As the adjustment only takes place at longer intervals can be made, a deeper one takes place as the wear progresses Penetration of the pull rod into the brake solenoid, so that a constantly changing Braking force results. As a result, overbraking occurs when the car is empty, which leads to Lead to the formation of flat spots on the grinding wheels.
Es ist ferner bei Kraftfahrzeugen bekannt, die Abstandsänderung der Bremsbacke zur Bremsscheibe selbsttätig über ein Sperrad durch ein Bremssolenoid auszugleichen. Derartige Anordnungen sind aber ausschließlich für einseitig angreifende Bremsbacken bestimmt.It is also known in motor vehicles, the change in distance Brake shoe to the brake disc automatically via a ratchet wheel by a brake solenoid balance. Such arrangements are only for unilateral attackers Brake shoes determined.
Die bekannten Bremssolenoide haben lediglich die Aufgabe, als elektrische Bremszylinder zu arbeiten, die entweder durch eine Batterie oder über die Fahrmotore und deren Bremswiderstände gespeist werden. Um den Abstand der Bremsbacken zur Bremsscheibe gleichmäßig zu halten, ist bei einer Ausführung nach einem älteren Patent am Bremssolenoid ein Kontakttaster angeordnet, der in Reihe mit einem Nachstellsolenoid geschaltet ist. Beim Schließen des Stromkreises durch den Kontakttaster wird der Zugstangenanker des Nachstellsolenoids betätigt und verstellt über ein Sperrad das Bremsgestänge.The known brake solenoids only have the task of being electrical Brake cylinders work either through a battery or through the traction motors and their braking resistors are fed. About the distance between the brake shoes and the brake disc to keep it evenly, is in a design according to an older patent on the brake solenoid a contact button is arranged, which is connected in series with an adjustment solenoid is. When the circuit is closed by the contact button, the tie rod anchor of the adjustment solenoid is actuated and the brake linkage is adjusted via a ratchet wheel.
Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung zu schaffen, durch die zwei entgegengesetzt auf eine Bremsscheibe wirkende Bremsbacken durch ein Nachstellsolenoid gleichmäßig und gleichzeitig bei Abstandsänderungen verstellt werden.The invention is based on the object of creating an arrangement through the two oppositely acting brake shoes on a brake disc an adjustment solenoid adjusts evenly and at the same time when the distance changes will.
Erfindungsgemäß wird die gestellte Aufgabe in der Weise gelöst, daß die beidseitig der Bremsscheibe angeordneten Bremsbacken auf einer gemeinsamen, mit gegenläufigem Gewinde ausgestatteten Spindel angeordnet sind, deren freies Ende das Sperrad für das Nachstellsolenoid trägt.According to the invention the object set is achieved in such a way that the brake shoes arranged on both sides of the brake disc on a common, arranged with opposing thread equipped spindle, the free end carries the ratchet wheel for the adjustment solenoid.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.
Beiderseits der auf der Radachse fest sitzenden Bremsscheibe 1 ist je eine Bremsbacke 2 mit Bremsbelag 3 vorgesehen, die durch Verschieben axial zur Radachse an die Bremsscheibe 1 anpreßbar sind. Über ein Gestänge beliebiger Bauart sind die Bremsbacken 2 mit Bremszangen 4 verbunden, die ihrerseits auf Bolzen 5 von Stangenköpfen 6 und 6' beweglich gelagert sind. Die Stangenköpfe 6 und 6' haben Links- bzw. Rechtsgewinde und sind durch eine mit gegenläufigem Gewinde versehene gemeinsame Spindel 7 miteinander verbunden. Die Spindel 7 ist durch den Stangenkopf 6' hindurchgeführt. Das freie Ende 7a der Spindel ist als Vierkant ausgebildet und mit einem Sperrad 8 versehen. Ferner ist auf dem freien Ende 7a ein Nachstellsolenoid 9 bekannter Bauart gelagert, dessen Ankerzugstange exzentrisch in das Sperrad 8 eingreift.On both sides of the brake disc 1, which is firmly seated on the wheel axle each a brake shoe 2 with brake lining 3 is provided, which by moving axially to The wheel axle can be pressed against the brake disc 1. Via any type of linkage the brake shoes 2 are connected to brake calipers 4, which in turn are mounted on bolts 5 are movably mounted by rod heads 6 and 6 '. The rod ends have 6 and 6 ' Left-hand or right-hand thread and are provided with a counter-threading common spindle 7 connected to one another. The spindle 7 is through the rod head 6 'passed through. The free end 7a of the spindle is designed as a square and provided with a ratchet wheel 8. Furthermore, an adjustment solenoid is located on the free end 7a 9 of known design stored, the anchor pull rod eccentrically in the ratchet 8 intervenes.
Verändert sich der Abstand der Bremsbeläge 3 zur Bremsscheibe 1, so werden elektrische Kontakte in einem getrennten Steuerstromkreis geschlossen, wodurch Strom in das den Zugstangenanker umgebende Solenoid geleitet, die Zugstange angezogen und das Sperrad 8 in Drehbewegung versetzt wird. Bei Drehung des Sperrades 8 bewegen sich die Stangenköpfe 6 und 6' derart, daß entsprechend der Gewindesteigung und der Übersetzung die Bremsbacken 2 mit dem Bremsbelag 3 auf den Betriebsabstand kommen. Wird der Betriebsabstand erreicht, so werden die elektrischen Kontakte geöffnet, und das Solenoid wird stromlos, so daß die Zugstange in der gegebenen Lage verbleibt.If the distance between the brake pads 3 and the brake disc 1 changes, so electrical contacts are closed in a separate control circuit, whereby Current passed into the solenoid surrounding the tie rod armature, the tie rod tightened and the ratchet wheel 8 is set in rotary motion. Move while turning the ratchet wheel 8 the rod heads 6 and 6 'such that according to the thread pitch and the translation, the brake shoes 2 with the brake lining 3 come to the operating distance. If the operating distance is reached, the electrical contacts are opened, and the solenoid is de-energized so that the tie rod remains in the given position.
