Description

Vorrichtungen, welche ein Versagen der Bremsvorrichtung speziell bei Kraftfahrzeugen durch ein unvorhergesehenes Entleeren des Vorratbehälters infolge Leitungsbruchs oder sonstigen Ölverlust verhindern sollen, sind bereits bekannt. Devices that prevent failure of the braking device specifically in motor vehicles due to the storage container being emptied unexpectedly as a result To prevent line breakage or other oil loss are already known.

Bei den bereits bekannt gewordenen Vorrichtungen handelt es sich einesteils um eine solche, welche durch Auslösung eines Kontaktes ein Lämpchen aufleuchten läßt, anderseits um solche, welche automatisch einen anderen Reservebehälter einschalten. The devices that have already become known are on the one hand to one which lights up a lamp when a contact is triggered lets, on the other hand, those that automatically switch on another reserve tank.

Beide Ausführungen haben bisher keinen Eingang in die Praxis gefunden, weil die Vorrichtungen teilweise zu primitiv, teilweise zu kompliziert waren und ein verläßliches Arbeiten nicht unbedingt garantierten. Both versions have so far not found their way into practice, because the devices were partly too primitive, partly too complicated and did not necessarily guarantee reliable work.

Im Gegensatz zu einer bereits bekannten Anordnung, bei welcher die kontaktgebenden Organe, z B. die einen Schwimmer führende Stange, sich außerhalb des Gehäuses befindet und. leicht verbogen werden kann und dadurch die Funktion der Vorrichtung in Frage stellt, anderseits die Kontakte, die das Signal in Tätigkeit setzen sollen, frei liegen und verschmutzt werden können, vermeidet die Erfindung diese beiden wesentlichen Mängel. In contrast to an already known arrangement in which the organs making contact, e.g. the rod guiding a swimmer, are outside of the housing and. can easily be bent and thereby the function the device in question, on the other hand, the contacts that activate the signal should set, lie exposed and can be soiled, the invention avoids these two major shortcomings.

Sämtliche Einzelteile der Vorrichtung einschließlich der kontaktgebenden Stellen sind innerhalb des Vorratbehälters untergebracht und dadurch jeder .iuberlichen Einwirkung entzogen. All individual parts of the device including the contact-making Places are housed inside the storage container and therefore each No influence.

Auch aus wirtschaftlichen Gründen war ein nachträglicher Einbau der bekannt gewordenen Signal-\ orrichtungen in bereits bestehenden Bremsvorrichtungen z. B. wegen der hohen Umänderungskosten nicht ohne weiteres durchführbar, während bei der Vorrichtung gemäß der Erfindung die entstehenden Kosten in keinem Verhältnis zum Wert der Vorrichtung stehen. For economic reasons, too, the known signaling devices in existing braking devices z. B. not easily feasible because of the high conversion costs, while in the device according to the invention, the costs incurred in disproportionate stand for the value of the device.

Ein Ausführungsbeispiel der Erfindung ist in der Abbildung dargestellt. Die Abbildung zeigt die gesamte Vorrichtung. In dem bereits bekannten Vorratsbehälter 5 gleitet an einer am Deckel 6 befestigten Führungsstange 2 der mit der Fiihrungsstange 2 durch biegsame Litze I verbundene Schwimmer 3 entlang. Die Führungsstange 2 hat an ihrem unteren Ende zweckmäßig einen Ansatz, um das Herabfallen des Schwimmers 3 beim Entfernen desDeckels 6 beim Nachfüllen der Bremsflüssigkeit zu verhindern. An embodiment of the invention is shown in the figure. The figure shows the entire device. In the already known storage container 5 slides on a guide rod 2 attached to the cover 6 with the guide rod 2 floats 3 connected by flexible strand I along. The guide rod 2 has at its lower end an appropriate approach to prevent the float from falling 3 to prevent when removing the cap 6 when refilling the brake fluid.

Der Boden desVorratsbehälters 5 erhält eine Durchbohrung, durch welche der Kontaktstift 4, isoliert befestigt, in das Innere des Behälters hineinragt.The bottom of the storage container 5 is provided with a through-hole through which the contact pin 4, secured in isolation, protrudes into the interior of the container.

Sinkt der Schwimmer 3, bedingt durch den zu niedrigen Ölstand im Vorratsbehälter über das als Sicherheitsgrenze im voraus festgesetzte AlaB hinaus, so berührt der stromführende Schwimmer 3 mit seiner unteren Fläche den gleichfalls stromführenden Kontaktstift 4 und schließt dadurch einen Stromkreis, in den zweckmäßig ein Lämpchen o dgl. geschaltet ist, über eine Batterie, z. B. die Starter-I,atterie, kurz, wodurch dem Fahrer oder einer sonstigen mit der Wartung der Öldruckbremse betrauten Person ein sichtbares Zeichen gegeben wird, daß mit einem Versagen der Bremse gerechnet werden muß.If the float 3 sinks, due to the oil level in the storage tank being too low beyond the AlaB set in advance as a safety limit, the current-carrying float 3 with its lower surface is also current-carrying Contact pin 4 and thereby closes a circuit in which a lamp is appropriate o the like. Is connected via a battery, z. B. the starter-I, atterie, short, whereby the driver or another person entrusted with the maintenance of the oil pressure brake a visible sign is given that the brake is expected to fail must become.
