Abstract
Hydraulische Lenkung, umfassend: – ein Lenkgetriebe (1), – eine Lenkhilfepumpe (2), und – eine Verbindungsleitung (3) zwischen der Lenkhilfepumpe (2) und dem Lenkgetriebe (1), die einen als Dehnschlauch (10) ausgebildeten Abschnitt aufweist, gekennzeichnet durch – ein Rückschlagventil (11), das zwischen dem Dehnschlauch (10) und dem Lenkgetriebe (1) angeordnet ist, sowie – ein weiteres Rückschlagventil (12), das zwischen der Lenkhilfepumpe (2) und dem Dehnschlauch (10) angeordnet ist.A hydraulic steering system comprising: - a steering gear (1), - a power steering pump (2), and - a connecting line (3) between the power steering pump (2) and the steering gear (1) having a section formed as a stretch hose (10), characterized by - a check valve (11) disposed between the expansion hose (10) and the steering gear (1), and - another check valve (12) disposed between the power steering pump (2) and the expansion hose (10).
Description
Die Erfindung bezieht sich auf eine hydraulische Lenkung nach dem Oberbegriff von Patentanspruch 1. The invention relates to a hydraulic steering system according to the preamble of
Hydraulische Lenkungen mit einem Lenkgetriebe, einer Lenkhilfepumpe und einer Verbindungsleitung zwischen der Lenkhilfepumpe und dem Lenkgetriebe sind Stand der Technik. Beispielhaft seien hier lediglich
Weiterhin ist aus
Der Erfindung liegt die Aufgabe zu Grunde, bei einer solchen Lenkung von der Lenkhilfepumpe erzeugte Geräuschemissionen zu vermindern und Leckagen an der Pumpe zu vermeiden. The object of the invention is to reduce noise emissions generated by the power steering pump in such a steering and to avoid leaks at the pump.
Diese Aufgabe wird durch eine hydraulische Lenkung gemäß Patentanspruch 1 gelöst. This object is achieved by a hydraulic steering system according to
Insbesondere sind hierbei ein erstes Rückschlagventil zwischen dem Dehnschlauch und dem Lenkgetriebe angeordnet und ein weiteres Rückschlagventil zwischen der Lenkhilfepumpe und dem Dehnschlauch angeordnet. Durch die Anordnung des weiteren Rückschlagventils wirken Druckschwankungen in der Verbindungsleitung, insbesondere Rückschläge des Dehnschlauchs, nicht auf die Lenkhilfepumpe zurück. Dies führt zu einer geringeren mechanischen Belastung der Lenkhilfepumpe sowie verringerten Geräuschemissionen. Darüber hinaus werden durch das Vermeiden von hohen Druckbelastungen Leckagen an der Lenkhilfepumpe, insbesondere an deren Wellendichtring vermieden. In particular, in this case a first check valve between the expansion hose and the steering gear are arranged and arranged a further check valve between the power steering pump and the expansion hose. Due to the arrangement of the further check valve, pressure fluctuations in the connecting line, in particular setbacks of the expansion hose, do not act on the power steering pump. This leads to a lower mechanical load on the power steering pump and reduced noise emissions. In addition, avoided by avoiding high pressure loads leaks on the power steering pump, in particular at the shaft seal.
Das weitere Rückschlagventil kann beispielsweise in der Verbindungsleitung angeordnet werden. The further check valve can be arranged for example in the connecting line.
Zudem ist es möglich, das weitere Rückschlagventil in ein Gehäuse der Lenkhilfepumpe zu integrieren. In addition, it is possible to integrate the additional check valve in a housing of the power steering pump.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung wird das weitere Rückschlagventil unmittelbar am Hydraulikausgang der Lenkhilfepumpe angeordnet. According to an advantageous embodiment of the invention, the further check valve is arranged directly on the hydraulic output of the power steering pump.
Das erste Rückschlagventil kann in der Verbindungsleitung angeordnet oder aber in das Gehäuse des Lenkgetriebes integriert werden. The first check valve can be arranged in the connecting line or integrated into the housing of the steering gear.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung wird das erste Rückschlagventil, welches primär die Funktion übernimmt, die Übertragung von mechanischen Stößen an das hydraulische System, das heißt an die Verbindungsleitung zwischen dem Lenkgetriebe zu übertragen, unmittelbar am Hydraulikeingang des Lenkgetriebes angeordnet. According to an advantageous embodiment of the invention, the first check valve, which primarily assumes the function to transmit the transmission of mechanical shock to the hydraulic system, that is to transmit to the connecting line between the steering gear, located directly on the hydraulic input of the steering gear.
Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung zeigt in: The invention will be explained in more detail with reference to an embodiment shown in the drawing. The drawing shows in:
