Description

Es sind Druckluftbremsen bekannt, bei denen ein verhältnismäßig kleiner Anlegekolben über das Bremsgestänge das Anlegen der Bremsklötze an die Räder bewirkt, während die eigentliche Bremskraft durch einen größeren Kolben bewirkt wird, der erst, nachdem der kleine Kolben die Klötze angelegt hat, mit dem Gestänge in Eingriff kommt. Nachteil der bisherigen Einrichtungen ist der, daß die Vorrichtung, die den großen Kolben zum Eingriff mit dem Gestätige bringt, kompliziert und unsicher in der Wirkungsweise ist. Es ist Ziel der Erfindung, eine einfache Vorrichtung zu schaffen, die diese Nachteile vermeidet.Air brakes are known in which a relatively small The application piston causes the brake pads to be applied to the wheels via the brake linkage, while the actual braking force is provided by a larger piston, the only after the small piston has put the blocks into engagement with the linkage comes. The disadvantage of the previous devices is that the device that the large piston to engage with the gestures, complicated and unsafe in the mode of action is. The aim of the invention is to create a simple device which avoids these disadvantages.

Zu diesem Zweck wird ein Kniehebelpaar vorgesehen, auf das der Anlegekolben wirkt und das die Verschiebung eines Festpunktes des Bremsgestänges bewirkt und dadurch die Bremsklötze zum Anlegen bringt.For this purpose, a pair of toggle levers is provided on which the application piston acts and that causes the displacement of a fixed point of the brake linkage and thereby brings the brake pads to bear.

Die Abb. i und 2 zeigen die Vorrichtung im gelösten und angezogenen Zustand. Der Hauptbremszylinder i wirkt über das normale Mittelbremsgestänge mit den Hebeln 2 und 3 und der Zugstange 4 auf das Bremsgestänge. Der im Anlegezylinder 5 befindliche, verhältnismäßig kleine Kolben wirkt über ein Kniehebelpaar 7, 8, das einerseits im Festpunktbock 6 des Hauptbremszylinders i, andererseits an dem Bremshebel 3 angelenkt ist, über diesen Hebel auf das Bremsgestänge. Beim Bremsen wird zuerst der Anlegezylinder 5 mit Druckluft beschickt. Er wirkt auf das Kniehebelpaar und drückt es durch, so daß die Bremsklötze zum Anliegen kommen. Ist der Angriffspunkt des Anlegekolbens am Kniehebelpaar über den Totpunkt gelangt, so verhindert ein Anschlag im Bremszylinder oder an anderer Stelle das weitere Durchdrücken des Kniehebels. Die Anlenkungsstelle des Hebels 8 an den Bremshebel 3 wirkt dann als Festpunkt, das übrige Anziehen der Bremse erfolgt über den Zylinder i.Figs. I and 2 show the device in the released and tightened State. The master brake cylinder i acts via the normal central brake linkage the levers 2 and 3 and the pull rod 4 on the brake linkage. The one in the feed cylinder 5 located, relatively small piston acts via a pair of toggle levers 7, 8, on the one hand in the fixed point bracket 6 of the master cylinder i, on the other hand on the Brake lever 3 is articulated, via this lever on the brake linkage. When braking the feed cylinder 5 is first charged with compressed air. It acts on the pair of toggle levers and pushes it through so that the brake pads come to rest. Is the point of attack of the contact piston on the pair of toggle levers reaches the dead center, a Stop in the brake cylinder or at another point, further pressing the toggle lever. The articulation point of the lever 8 on the brake lever 3 then acts as a fixed point, the rest of the brake is applied via the cylinder i.

PATENTANSPRÜCHE: i. Druckluftbremse mit einem Anlegekolben und einem Festbremskolben, dadurch gekennzeichnet, daß im Bremsgestänge ein von dem Anlegekolben beeinflußtes Kniehebelwerk angeordnet ist, welches bei Ansprechen des Anlegekolbens das Anlegen der Bremsklötze bewirkt. PATENT CLAIMS: i. Compressed air brake with a contact piston and a locking piston, characterized in that a toggle lever mechanism influenced by the contact piston is arranged in the brake linkage and causes the brake pads to be applied when the contact piston responds. 2. Druckluftbremse nach Anspruch i, dadurch gekennzeichnet, daß der Hub des Anlegekolbens bei Überschreitung des Totpunktes des Kniehebelwerkes begrenzt ist.2. Air brake according to claim i, characterized in that the stroke of the application piston is exceeded when the Dead center of the toggle mechanism is limited.
