Abstract

Die Erfindung betrifft eine Anordnung zur hydraulischen Betätigung eines Heckdeckels, einer Abdeckklappe od. dgl. (1) an einem Fahrzeug, mit zumindest einem doppeltwirkenden hydraulischen Arbeitszylinder (3), der einerseits am Fahrzeug und andererseits an der Abdeckklappe angelenkt ist und dessen Arbeitsräume (8, 9) über je ein Rückschlagventil (10, 11) mit jeweils einer Seite einer umschaltbaren Druckquelle (12) in Verbindung stehen, wobei die beiden Rückschlagventile eine gegenseitige Entsperreinrichtung aufweisen und jeder der Arbeitsräume parallel zu den Rückschlagventilen über ein in den Tank absteuerndes Vorspannventil (15, 16) auf einem bestimmten Druckniveau gehalten ist. Um auf einfache und sichere Weise einen passiven Einklemmschutz zu realisieren, mündet in zumindest einer Anschlußleitung (4, 5) zum Arbeitszylinder (3) eine Leitung (22) zum Tank (17), in die ein Proportional-druckventil (23) eingesetzt ist, welches von der Steuerelektronik entsprechend dem zur Bewegung der Abdeckklappe (1) od. dgl. gerade notwendigen Druck angesteuert wird.

Figure 00000001
The invention relates to an arrangement for the hydraulic actuation of a boot lid, a cover flap or the like (1) on a vehicle, with at least one double-acting hydraulic working cylinder (3), which is articulated on the one hand on the vehicle and on the other hand on the cover flap and its working spaces (8 , 9) are each connected to one side of a switchable pressure source (12) via a non-return valve (10, 11), the two non-return valves having a mutual unlocking device and each of the working spaces parallel to the non-return valves via a pre-load valve that controls the tank ( 15, 16) is kept at a certain pressure level. In order to implement passive trap protection in a simple and safe manner, a line (22) to the tank (17), into which a proportional pressure valve (23) is inserted, opens into at least one connecting line (4, 5) to the working cylinder (3). which is controlled by the control electronics in accordance with the pressure just required to move the cover flap (1) or the like.
