Description

Selbsttätige Bremsvorrichtung an Anhängewagen. Die bekannten selbsttätigen Bremsvorrichtungen für Anhängewagen mit längsverschiebbarer, durch Schraubenfedern in unbelastetem Zustande in bestimmter Stellung gehaltenen Anhängestangen haben den Übelstand, daß sie schon bei verhältnismäßig geringem Druck auf die Anhängestange zur Wirkung kommen, und umgekehrt wird beim Aufhören eines Druckes auf die Anhängestange die Bremse ruckartig gelöst. Dadurch entstehen Schläge auf die Fahrzeuge, die schädlich auf diese wirken.Automatic braking device on the trailer. The well-known automatic ones Braking devices for trailers with longitudinally displaceable, by means of helical springs have hanging rods held in a certain position in the unloaded state the inconvenience that they are already under relatively little pressure on the tow bar come into effect, and vice versa when pressure is stopped on the tow bar the brake suddenly released. This causes blows to the vehicles that are harmful act on this.

Durch den Gegenstand der Erfindung soll diesem Übelstand dadurch begegnet werden, daß zwischen .die Anhängestange und die Bremsorgane an beliebig geeigneter Stelle des Anhängewagens in das Bremsgestänge besondere Flüssigkeitsbremsen bekannter Art eingeschaltet werden.The object of the invention is intended to counteract this drawback be that between .die towbar and the braking members at any suitable Place the trailer in the brake linkage special fluid brakes known Kind of be turned on.

Auf der Zeichnung ist der Erfindungsgegenstand in Ansicht in einem Ausführungsbeispiel dargestellt.In the drawing, the subject of the invention is in view in one Embodiment shown.

An der Achse i des zweirädrigen Anhängewagens (der Oberbau desselben ist nicht gezeichnet) befindet sich eine Gabel a mit Nabe 3, in der die Anhängestange q. gelagert ist. Diese Stange q. steht 'in gelenkiger Verbindung mit den Enden a, b der zweiarmigen Hebel 8, g. Die Enden io, i i dieser Hebel stehen durch Gelenkstangen 12, 13 -in Verbindung mit den Bremsorganen 1q., 15, die auf die Bremsringe 18, 19 der Räder 16, 17 wirken An den Drehstellen c, c' der Doppelhebel 8, 9 sind mit diesen Hebeln zusammenwirkende Flüssigkeitsbremsen bekannter Art angeordnet zwecks Regulierung der Schwingbewegung dieser Hebel.On the axis i of the two-wheeled trailer (the superstructure of the same is not shown) there is a fork a with a hub 3, in which the trailer rod q. is stored. This rod q. is' in an articulated connection with the ends a, b of the two-armed lever 8, g. The ends io, i i of these levers are connected by articulated rods 12, 13 -in connection with the braking elements 1q., 15, which act on the brake rings 18, 19 of the wheels 16, 17 fluid brakes of known type cooperating with these levers are arranged for the purpose of regulating the oscillating movement of these levers.

Die Bremsvorrichtung wirkt wie folgt: Wird aus irgendeinem Grunde der Anhängewagen gegen das Fahrzeug, an das er angehängt ist, gestoßen, so wird die Stange q. in der Pfeilrichtung nach rückwärts gedrückt, die Hebel 8, 9 schwingen aus (wobei die zwischengeschalteten, auf die Hebel einwirkenden regulierbaren Flüssigkeitsbremsen 5, 6 eine lange Bremswirkung bzw. Lösung der Bremsung ,bewirken); und die Bremsklötze werden angezogen. Läßt der Druck auf die Stangen q. nach, so lösen sich die Bremsklötze von den Ringen 18, z9.The braking device works as follows: Will for some reason the trailer bumped against the vehicle to which it is attached the rod q. pushed backwards in the direction of the arrow, the levers 8, 9 swing off (with the interposed, adjustable fluid brakes acting on the levers 5, 6 cause a long braking effect or release of the braking); and the brake pads are attracted. If the pressure on the rods q. after, the brake pads will loosen from rings 18, z9.

Selbstredend kann :die Bremsüng auf die Räder auf beliebig geeignete Art geschehen, so z. B. auch durch Bandbremsen oder durch Wirkung von Bremsklötzen auf die Radfelgen. Ebenso kann, z. B. .bei vierrädrigen Anhängewagen, auch das hintere Räderpaar mit dieser Bremsvorrichtung gebremst werden. Es kommen Fälle vor, wo der Anhängewagen durch den Vorwagen rückwärts ge-. stoßen werden soll, ohne daß hierbei die Bremsorgane des Anhängewagens in Tätigkeit treten sollen. Zu diesem Zwecke ist an der Gabel e eine Sperrvorrichtung' für die Anhängestange vorgesehen. Sie besteht aus einer umlegbaren Klinke 2ö, deren freies gabelförmig gestaltetes Ende so an den Flansch 2,1 der Öse 22 gestützt werden kann, daß ein Rückwärtsstoßen der Stange q. verhindert wird.It goes without saying that: the braking on the wheels at any suitable rate Kind of happen, so z. B. also by band brakes or by the action of brake pads on the wheel rims. Likewise, z. B.. With four-wheel trailer, also the rear one Pair of wheels are braked with this braking device. There are cases where the The trailer wagon backwards through the front car. should be encountered without doing this the braking system of the trailer should come into action. To this end is a locking device for the tow bar is provided on the fork e. she consists from a foldable pawl 2ö, whose free fork-shaped end so on the flange 2.1 of the eyelet 22 can be supported that pushing the rod backwards q. is prevented.
