der
Bei einem Fehler, der in einem der hydraulischen Steuerkreise für eine Leitungsverstopfung führt, kann es innerhalb der Versorgungsvorrichtung zu unzulässig hohen hydraulischen Drücken kommen, was zu einer Beschädigung einzelner Komponenten führen kann.at an error in one of the hydraulic control circuits for leads to a clogging, it can within the supply device to Inadmissibly high hydraulic pressures come, resulting in damage to individual components can.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine hydraulische Versorgungsvorrichtung der eingangs genannten Art eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch charakterisiert, dass die Gefahr einer Beschädigung im Fehlerfall reduziert ist.The The present invention addresses the problem of for a hydraulic supply device of the beginning to specify an improved embodiment, which is characterized, in particular, by the risk of a Damage is reduced in the event of a fault.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the objects of the independent claims. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, einen der Vorläufe mit einem der Rückläufe über einen Bypass miteinander hydraulisch zu verbinden und in diesem Bypass eine Druckbegrenzungseinrichtung anzuordnen. Auf diese Weise kann ab einem vorbestimmten Überdruck im jeweiligen Vorlauf die Druckbegrenzungseinrichtung den Bypass öffnen und eine Entspannung in den jeweiligen Rücklauf ermöglichen. Hierdurch kann die Gefahr einer Beschädigung durch Überdruck im Fehlerfall reduziert werden. Von besonderem Vorteil ist es dabei, dass zum Schutz des jeweiligen hydraulischen Steuerkreises nur ein Bypass mit Druckbegrenzungseinrichtung vorgesehen werden muss, da die Rückläufe direkt miteinander hydraulisch gekoppelt sind.The Invention is based on the general idea, one of the heats with one of the returns via a bypass hydraulically connect to each other and in this bypass a pressure relief device to arrange. In this way, from a predetermined overpressure open the bypass in each flow the pressure relief device and allow relaxation in the respective return. This may increase the risk of damage due to overpressure be reduced in case of error. Of particular advantage is that to protect the respective hydraulic control circuit only one bypass must be provided with pressure relief device, since the returns directly hydraulically coupled to each other.
Entsprechend einer besonders einfachen Ausführungsform kann die Druckbegrenzungseinrichtung ein Druckbegrenzungsventil sein oder umfassen.Corresponding In a particularly simple embodiment, the pressure limiting device be or include a pressure relief valve.
Zweckmäßig ist die Druckbegrenzungseinrichtung unmittelbar an demjenigen Steueranschluss angeordnet, an dem der mit dem Bypass verbundene Vorlauf angeschlossen ist. Hierdurch wird eine vergleichsweise kompakte Bauform realisiert.expedient the pressure limiting device is arranged directly on that control connection, where the bypass connected to the bypass is connected. As a result, a comparatively compact design is realized.
Besonders vorteilhaft ist eine Ausführungsform, bei welcher die Druckbegrenzungseinrichtung baulich in die Stromteilereinrichtung integriert ist. Mit anderen Worten, Bypass und Druckbegrenzungseinrichtung sind innerhalb der Stromteilereinrichtung realisiert.Especially advantageous is an embodiment in which the pressure limiting device structurally is integrated in the flow divider. In other words, Bypass and pressure limiting device are realized within the flow divider.
Die Druckbegrenzungseinrichtung kann bezüglich der Stromteilereinrichtung auch ein separates Bauteil sein, so dass der Bypass diesbezüglich extern ist und quasi beliebig innerhalb des Hydrauliksystems positionierbar ist.The Pressure limiting device can with respect to the flow divider also be a separate component so that the bypass in this regard is externally and virtually arbitrarily positionable within the hydraulic system is.
Bevorzugt ist die Versorgungsvorrichtung als aktive Stabilisierungsvorrichtung für ein mehrachsiges Fahrzeug ausgestaltet, die je einen hydraulischen Steuerkreis für eine Vorderachse und eine Hinterachse des Fahrzeugs aufweist. Eine derartige aktive Wankstabilisierung kann erheblich zur Steigerung des Fahrkomforts beitragen.Prefers the supply device is an active stabilization device designed for a multi-axle vehicle, each one hydraulic control circuit for a front axle and a Has rear axle of the vehicle. Such an active roll stabilization can significantly increase driving comfort.
Sofern die beiden Steuerkreise mit unterschiedlichen Betriebsdrücken arbeiten, was bei einer Ausgestaltung der Versorgungsvorrichtung als aktive Stabilisierungsvorrichtung regelmäßig der Fall sein kann, ist der Bypass zweckmäßig an den Vorlauf desjenigen Steuerkreises angeschlossen, der den niedrigeren Betriebsdruck aufweist. Bei dieser Ausführungsform muss die Druckbegrenzungseinrichtung nur für den niedrigeren Betriebsdruck ausgelegt werden, wodurch sie kostengünstiger realisierbar ist.Provided the two control circuits with different operating pressures work, which in one embodiment of the supply device as an active stabilizer regularly the case may be, the bypass is convenient connected to the supply of the control circuit, the lower Operating pressure has. In this embodiment must the pressure limiting device only for the lower one Operating pressure are designed, making them more cost-effective is feasible.
Bevorzugt verbindet der Bypass den Vorlauf des der Hinterachse zugeordneten Steuerkreises mit einem der Rückläufe, um den Hinterachssteuerkreis vor Überdruck zu schützen.Prefers the bypass connects the flow of the rear axle associated Control circuit with one of the returns to the Rear axle control circuit to protect against overpressure.
Schließlich betrifft die vorliegende Erfindung noch eine Stromteilereinrichtung, in welche die Druckbegrenzungseinrichtung baulich integriert ist.After all the present invention also relates to a current divider device, in which the pressure limiting device is structurally integrated.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus der Zeichnung und aus der zugehörigen Figurenbeschreibung anhand der Zeichnung.Other important features and benefits of Invention will become apparent from the dependent claims, from the drawing and from the associated figure description with reference to the drawing.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It it is understood that the above and the following yet to be explained features not only in each case specified combination, but also in other combinations or can be used in isolation, without the scope of the present To leave invention.
