Description
Die Erfindung betrifft eine hydraulische Druckregelvorrichtung für ein aktives Fahrwerkregelungssystem, mit einer Pumpe zur Erzeugung eines Fluiddrucks, der über wenigstens zwei getrennte Leitungszweige wenigstens zwei Hydraulikanschlüssen zugeführt wird.The The invention relates to a hydraulic pressure control device for an active Suspension control system, with a pump for generating a fluid pressure, the over at least two separate line branches at least two hydraulic connections is supplied.
Es sind sowohl Regelsysteme zur Reduzierung des Rollwinkels eines Fahrzeugs als auch Regelsysteme zur Beeinflussung des Unter/Übersteuerverhaltens eines Fahrzeugs bekannt. Ein Kompromiß zwischen beiden Funktionen kann durch ein kombiniertes Fahrwerkregelungssystem mit hydraulisch betriebenen, z.B. an die Stabilisatoren des Fahrzeugs gekoppelten Aktuatoren erreicht werden, wobei die Drücke, mit denen die Aktuatoren beaufschlagt werden, separat eingestellt werden.It are both control systems for reducing the roll angle of a vehicle as well as control systems for influencing the under / oversteer behavior a vehicle known. A compromise between both functions can be achieved by a combined suspension control system with hydraulically operated, e.g. to the stabilizers of the vehicle coupled actuators be reached, the pressures, with which the actuators are acted upon, set separately become.
Eine
hydraulische Druckregelvorrichtung nach dem Stand der Technik, die
eine solche Steuerung umsetzt, ist in
Eine andere bekannte Druckregelvorrichtung basiert auf einer Kombination eines Druckbegrenzungsventils und eines Druckminderventils. Allerdings ist die Leistungsfähigkeit einer solchen Druckregelvorrichtung eingeschränkt.A Another known pressure control device is based on a combination a pressure relief valve and a pressure reducing valve. Indeed is the efficiency limited such a pressure control device.
Es ist daher eine hydraulische Druckregelvorrichtung für ein aktives Fahrwerkregelungssystem wünschenswert, die ohne Prioritätsventil auskommt, aber dennoch zuverlässig die gewünschte Leistung in Bezug auf die Aktuatorbetätigung zur Rollwinkelreduzierung und zur Beeinflussung des Unter/Übersteuerverhaltens bietet.It is therefore a hydraulic pressure control device for an active Suspension control system desirable, the without priority valve gets along, but still reliable the desired Power in relation to the actuator operation for roll angle reduction and for influencing the under / oversteer behavior offers.
Die Erfindung schlägt vor, bei einer hydaulischen Druckregelvorrichtung der eingangs genannten Art ein Druckminderventil, das in einem der beiden Leitungszweige angeordnet ist, und ein Druckrichtungssteuerventil vorzusehen, mit dem wahlweise der erste Leitungszweig an den ersten Hydraulikanschluß und der zweite Leitungszweig an den zweiten Hydraulikanschluß, oder der erste Leitungszweig an den zweiten Hydraulikanschluß und der zweite Leitungszweig an den ersten Hydraulikanschluß gekoppelt werden kann. Auf diese Weise können zwei mit den Hydraulikanschlüssen verbundene Aktuatoren mit zwei unterschiedlichen Drücken unabhängig voneinander betrieben werden. Die erfindungsgemäße Druckregelvorrichtung hat den Vorteil, daß für beide Aktuatoren das volle Leistungsspektrum von Null bis zum maximalen Systemdruck abgerufen werden kann, ohne daß dafür ein Prioritätsventil erforderlich ist. Die Bereitstellung eines zweiten, gegenüber dem vom Druckbegrenzungsventil eingestellten Hauptdruck verringerten Druckniveaus erfolgt durch das Druckminderventil. Mit dem Druckrichtungssteuerventil kann dann ausgewählt werden, welcher Druck welchem Aktuator zugeführt wird. Im Vergleich zu einer Druckregelvorrichtung mit einem Prioritätsventil findet bei der erfindungsgemäßen Druckregelvorrichtung keine gegenseitige Beeinflussung der beiden hydraulischen Leitungszweige statt, was zu einem höheren Fahrkomfort und einer verminderten Geräuschentwicklung führt. Da der erfindungsgemäße Aufbau der Druckregelvorrichtung kein Prioritätsventil vorsieht, ist die Vorrichtung auch weniger temperaturanfällig, und die Gefahr von Fluidkontaminationen ist verringert. Die erfindungsgemäße Druckregelvorrichtung hat weiterhin den Vorteil des geringeren Flußbedarfs.The Invention proposes before, in a hydaulic pressure control device of the aforementioned Kind a pressure reducing valve, which in one of the two line branches is arranged, and to provide a pressure direction control valve, with optionally the first line branch to the first hydraulic connection and the second line branch to the second hydraulic connection, or the first leg to the second hydraulic connection and the second line branch coupled to the first hydraulic connection can be. That way you can two with the hydraulic connections connected actuators with two different pressures independently operate. The pressure control device according to the invention has the advantage that for both Actuators the full power range from zero to maximum System pressure can be retrieved without requiring a priority valve is required. The provision of a second, opposite from the Pressure relief valve set main pressure reduced pressure levels done by the pressure reducing valve. With the pressure direction control valve can then be selected which pressure is supplied to which actuator. Compared to one Pressure control device with a priority valve found in the pressure control device according to the invention no mutual influence of the two hydraulic line branches instead, leading to a higher one Driving comfort and a reduced noise level leads. There the structure of the invention the pressure control device does not provide a priority valve is the Device also less susceptible to temperature, and the risk of fluid contamination is reduced. The pressure control device according to the invention has furthermore the advantage of the lower flow requirement.
Die Bereitstellung eines definierten Hauptdrucks für die erfindungsgemäße Druckregelvorrichtung erfolgt vorzugsweise durch ein Druckbegrenzungsventil, mit dem der von der Pumpe erzeugte Fluiddruck auf einen vorbestimmten Wert eingestellt wird.The Provision of a defined main pressure for the pressure control device according to the invention is preferably carried out by a pressure relief valve, with which the pump pressure generated by the pump is set to a predetermined value.
