Abstract
Description
Die Erfindung betrifft eine Trommelbremse mit den Merkmalen des Oberbegriffs der Ansprüche 1 und 2.The The invention relates to a drum brake with the features of the preamble of claims 1 and 2.
Eine
Trommelbremse mit diesen Merkmalen ist aus der
Der Erfindung liegt die Aufgabe zugrunde, eine automatisch nachstellbare und mit einer Rückfahrtautomatik versehene Trommelbremse mit einfachem Aufbau zu schaffen.Of the Invention is based on the object, an automatically adjustable and with a reverse drive provided drum brake to create with a simple structure.
Zur Lösung dieser Aufgabe wird eine Trommelbremse mit den Merkmalen der Ansprüche 1 und 2 vorgeschlagen.to Solution to this problem is a drum brake with the features of claims 1 and 2 proposed.
Die Verhinderung der Nachstellung im Falle der Rückwärtsfahrt des Fahrzeuges wird also nicht durch aufwändige, getriebekinematische Mittel erreicht, sondern durch eine konstruktiv einfach gestaltbare Trenneinrichtung, welche bei Rückwärtsfahrt des Fahrzeuges den Antrieb des Stellglieds aufhebt. Diese Trenneinrichtung ist vorzugsweise gekoppelt mit der in die Trommelbremse integrierten Rückfahrtautomatik.The Prevention of re-adjustment in case of reversing The vehicle is therefore not by consuming, gear kinematics Means achieved, but by a structurally simple designable Separating device, which when reversing the Vehicle picks up the drive of the actuator. This separator is preferably coupled with the integrated in the drum brake reverse drive.
Mit einer Ausgestaltung der Trommelbremse wird vorgeschlagen, dass das Stellglied der Nachstellvorrichtung ein gezahntes Ritzel ist, in das das Nachstellelement formschlüssig eingreift, und dass der Formschluss mittels der Trenneinrichtung aufhebbar ist. Mit einer weiteren Ausgestaltung wird eine Feder vorgeschlagen, welche das Nachstellelement in Richtung auf den formschlüssigen Eingriff in das Ritzel beaufschlagt.With an embodiment of the drum brake is proposed that the Actuator of the adjuster is a toothed pinion, in that positively engages the adjusting element, and that the Positive locking can be canceled by means of the separating device. With another Embodiment, a spring is proposed which the adjusting element in Direction to the positive engagement in the pinion applied.
Gemäß einer weiteren Ausgestaltung ist die Feder an einem starr am Bremsschild angeordneten Bolzen festgelegt, und das Nachstellelement sitzt mit einer darin ausgebildeten Langlochführung auf dem Bolzen.According to one Another embodiment, the spring on a rigid brake plate arranged bolt, and the adjusting element sits with a formed therein slot guide on the bolt.
Gemäß einer weiteren Ausgestaltung weist die Trenneinrichtung mindestens ein rampenförmiges Übertragungsglied auf.According to one Another embodiment, the separation device at least one ramp-shaped transmission member.
Gemäß einer weiteren Ausgestaltung dient als Nachstellelement ein Schub- und Zugelement, welches an seinem einen Ende den Antrieb des Stellglieds, und an seinem anderen Ende eine Gelenkverbindung des Getriebes der Nachstellvorrichtung aufweist, und welches auf einem dazwischen angeordneten Längsabschnitt durch eine Führung hindurchgeführt ist. Vorzugsweise weist die Führung des Schub- und Zugelements einen kürzeren Abstand zu der Gelenkverbindung auf, als zu dem Stellglied.According to one Another embodiment serves as adjuster a push and Tension element, which at one end drives the actuator, and at its other end a hinge connection of the transmission of the Adjusting device has, and which on one in between arranged longitudinal section through a guide passed through. Preferably, the guide the push and pull element a shorter distance to the Articulated connection, as to the actuator.
Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines auf der Zeichnung dargestellten Ausführungsbeispieles. Im Einzelnen zeigen:Further Advantages and details will become apparent from the following description an embodiment shown on the drawing. in the Show individual:
Die dargestellte Trommelbremse vom Bautyp einer Spreizhebelbremse dient dem Einsatz in auflaufgebremsten Anhängerfahrzeugen, die mit einer Rückfahrtautomatik versehen sind.The shown drum brake construction type of Spreizhebelbremse used the use in run-braked trailer vehicles, the are provided with a return automatic.
