Description

Bremsölbehälter für Kraftfahrzeuge Die bisher übliche Anordnung der Öldruckbremsen für Kraftfahrzeuge läßt insofern Mängel erkennen, als ,die Behälter der Öldruckpumpen meist schwer zugänglich sind und es vieler zeitraubender Maßnahmen bedarf, um den jeweiligen Ölstand einwandfrei nachprüfen zu können. Eine Folge davon ist, daß der Zustand der Bremsen in der Regel nur von ganz gewissenhaften Fahrern Überprüft und in Ordnung gehalten wird, so daß ein großer Teil der Unfälle auf mangelhafte Wirkung der Öldruckbremsen infolge Ölmangels zurückzuführen ist.Brake oil tank for motor vehicles The previously common arrangement of Oil pressure brakes for motor vehicles can be identified as deficiencies, as the container the oil pressure pumps are usually difficult to access and there are many time-consuming measures required in order to be able to properly check the respective oil level. A consequence of that is that the condition of the brakes is usually only used by very conscientious drivers Checked and kept in order, so that a large part of the accidents are defective Effect of the oil pressure brakes is due to a lack of oil.

Es ist ferner bekannt, daß die Entlüftung in der Regel nur in einer Reparaturwerkstätte durch geübte Fachkräfte und unter viel Zeitaufwand wegen des notwendigen Aufbockens des Fahrzeuges und Abnahme ;der Räder vorgenommen werden kann. Es ist jedoch bekannt, uni Störungen in der Öldruckbrems- , leitung _ anzuzeigen, akustische oder optische Signale zu verwenden. Eine solche Ausführung sieht z. B. eine besondere, durch Handhebel zu betätigende Flüssigkeitspurripe vor, deren Hebel bei starkem, durch Flüssigkeitsverluste bedingtem Fallen des Pumpenkolbens, einen auf die Pumpe aufgesetzten Schalter betätigt, um so eine Warnlampe noch vor demVersagen der Bremse amArmaturenbrett aufleuchten zu lassen. Diese unter der Motorhaube angeordnete Einrichtung ist jedoch vorn Führersitz aus nicht erkennbar, sie bedarf außerdem zur Kenntlichmachung des jeweiligen Ölstandes der besonderen Handbetätigung, die nur bei stillstehendem Fahrzeug möglich ist. Bei einer anderen, ebenfalls auf optischem Wege wirkenden Vorrichtung ist ein Reservebehälter in zwei Ölkammern unterteilt, die durch ein Ventil miteinander in Verbindung stehen und deren innerer Behälter einen bei eintretendem Bruch der Ölleitung und bei Ölverlust in seine Tiefstlage fallenden Schwimmer aufweist. Dieser veranlaßt die Schließung elektrischer Kontakte, so daß entweder eine elektrische Kontrolllampe zum Aufleuchten gebracht oder ein anderes, z. B. akustisches Signal an den Fahrer abgegeben wird.It is also known that the vent is usually only in one Repair workshop by trained specialists and taking a lot of time because of the necessary jacking up of the vehicle and removal of the wheels can. However, it is known to indicate malfunctions in the oil pressure brake line, to use acoustic or optical signals. Such an embodiment sees z. B. a special liquid spur pipe to be operated by hand lever, the lever of which if the pump piston falls sharply due to fluid loss, a The switch placed on the pump is actuated to provide a warning light before failure the brake light on the dashboard. These are arranged under the bonnet However, the facility cannot be seen from the driver's seat; it is also required to identify the respective oil level of the special manual operation that is only possible when the vehicle is stationary. With another, also on optical Way-acting device is a reserve tank divided into two oil chambers, which are in communication with each other through a valve and their inner container one in the event of a break in the oil line and in the event of an oil loss in its lowest position has falling float. This causes electrical contacts to close, so that either an electric control lamp is lit up or one other, z. B. acoustic signal is given to the driver.

Von diesen Ausführungen unterscheidet sich .die Erfindung vorteilhafterweise dadurch, daß Ader mit einem Schauglas versehene Ölbehälter gut sichtbar vor die Blickrichtung des Fahrers an das Armaturenbrett verlegt und die vier Bremszylinder durch je eine besondere Leitung mit !dem Ölbehälter in Verbindung gebracht werden. Jede dieser Leitungen ist unterhalb des Ölbehälters mit einem Abstellhahn versehen. der zum Zwecke des Entlüftens geöffnet werden kann. Bei dem hierauf folgenden mehrmaligen Aüfundniederdrücken des Fußbremshebels zeigen sich zunächst Luftblasen im Ölbehälter, und der betreffende Hahn kann in dem Augenblick, wo keine Blasenbildung mehr erkennbar, id. h. die Leitung entlüftet ist, sofort abgestellt werden.The invention advantageously differs from these embodiments by the fact that the vein with a sight glass is clearly visible in front of the oil tank The driver's line of sight moved to the dashboard and the four brake cylinders are connected to the oil tank by a special pipe. Each of these lines is provided with a shut-off valve below the oil tank. which can be opened for the purpose of venting. In the subsequent multiple When the foot brake lever is depressed, air bubbles will initially appear in the oil tank, and the tap in question can, at the moment when no more blistering can be seen, id. H. the line is vented, shut down immediately.

Auf der Zeichnung ist ein Ausführungsbeispiel in zweiAbbildungen dargestellt; es zeigt Abb. i die schematische Anordnung der Öldruckleitung, Abb. :2 eine Einzelheit.In the drawing, an embodiment is shown in two figures; Fig. i shows the schematic arrangement of the oil pressure line, Fig. 2 shows a detail.

Gemäß der Erfindung ist am Armaturenbrett u ein mit Schauglas b versehener Ölbehälter c angebracht, der mit einem Einfüllstutzen d ausgestattet wird. An dem Boden des Ölbehälters c ist eine zur Öldruckpumpe e führende Leitung f angeschlossen, die in bekannter Weise wirkt und betätigt wird. Ferner sind durch den Olbehälterboden vier zu den einzelnen Bremszylindern g führende Rückleitungen h angebracht, deren jede mit einem Absperrhahn 7 versehen ist. Die Entlüftung der einzelnen Leitungen kann auf diese Weise vom Fahrer selbst und vom Führersitz aus vorgenommen werden.According to the invention, an oil tank c provided with a sight glass b is attached to the dashboard u and is equipped with a filler neck d. A line f leading to the oil pressure pump e is connected to the bottom of the oil container c and acts and is actuated in a known manner. Furthermore, four return lines h leading to the individual brake cylinders g are attached through the oil container base, each of which is provided with a shut-off valve 7. In this way, the individual lines can be vented by the driver himself and from the driver's seat.
