Hydropneumatisch abgefederter SitzHydropneumatically suspended seat

für Fahrzeuge, insbesondere Kraftfahrzeuge.for vehicles, in particular motor vehicles.

Die Erfindung betrifft einen hydropneumatisch abgefederten Sitz für Fahrzeuge, insbesondere Kraftfahrzeuge, der sich auf einem hydraulischen Verdrängerelement abstützt, das an ein einen Hydraulikraum und einen Gasraum aufweisendes Federungssystem angeschlossen ist.The invention relates to a hydropneumatically sprung seat for vehicles, in particular motor vehicles, which is on a hydraulic displacement element is supported, which is connected to a suspension system having a hydraulic space and a gas space connected.

Bei einem bekannten Sitz der eingangs genannten Gattung (DE-AS 21 11 574) erfolgt die Federung ohne Berücksichtigung der Vertikalbewegungen der ungefederten Massen (Räder, Achsen oder dergleichen), so daß die Insassen durch Fahrbahnunebenheiten angehoben und abgesenkt werden, was den Komfort eines Fahrzeuges beeinträchtigt.In a known seat of the type mentioned (DE-AS 21 11 574), the suspension takes place without taking into account the Vertical movements of the unsprung masses (wheels, axles or the like), so that the occupants through uneven road surfaces be raised and lowered, which affects the comfort of a vehicle.

Aufgabe der Erfindung ist es daher, an einem hydropneumatisch abgefederten Sitz solche Vorkehrungen zu treffen, daß neben einer effizienten Federung auch noch die beim überfahren von Fahrbahnunebenheiten entstehenden Vertikalbewegungen des Fahrzeuges ausgeglichen werden.The object of the invention is therefore to take such precautions on a hydropneumatically cushioned seat that in addition to an efficient suspension also the vertical movements of the when driving over uneven road surfaces Vehicle to be compensated.

Nach der Erfindung wird diese Aufgabe dadurch gelöst, daß ein an sich bekanntes Führungsglied eines Rades des Fahrzeuges eine durch Vertikalbewegungen des Rades betätigte Kolben-Zylinder— Einheit umfasst, die mit dem Federungssystem verbunden ist, dergestalt, daß der Sitz entgegengesetzt den Bewegungen des Rades und des Aufbaues betätigt wird. Hierzu ist es von Vorteil, wenn der Regelraum der Kolben-Zylindereinheit an die Hydraulikseite des Federungssystems angeschlossen ist. Auch besteht die Möglichkeit, den Regelraum der Kolben-Zylinder-Einheit an die Gasseite des Federungssystems anzuschließen.According to the invention, this object is achieved in that a known guide member of a wheel of the vehicle is a piston-cylinder actuated by vertical movements of the wheel Comprises unit that is connected to the suspension system, such that the seat opposes the movements of the Wheel and the structure is operated. For this purpose, it is advantageous if the control space of the piston-cylinder unit is connected to the Hydraulic side of the suspension system is connected. There is also the possibility of adjusting the control space of the piston-cylinder unit to be connected to the gas side of the suspension system.

Die mit der Erfindung insbesondere erzielten Vorteile sind darin zu sehen, daß durch die Kolben-Zylinder-Einheit am Radführungsglied die Fahrbahnunebenheiten nicht oder nur in geringem Umfang auf den Sitz übertragen werden, da dieser entgegen den vertikalen Bewegungen des Rades bewegt wird.The advantages achieved by the invention in particular are to be seen in the fact that the piston-cylinder unit on Wheel guide member, the unevenness of the road surface is not or only to a small extent transferred to the seat, since this is moved against the vertical movements of the wheel.

In der Zeichnung werden Ausführungsbeispiele der Erfindung näher erläutert. Es zeigtExemplary embodiments of the invention are explained in more detail in the drawing. It shows

Fig. 1 eine schematische Teilseitenansicht eines Kraftfahrzeuges mit dem erfindungsgemäßen Sitz, Fig. 2 eine Teilansicht der Fig. 1 einer weiteren Ausführungsform .1 shows a schematic partial side view of a motor vehicle with the seat according to the invention, FIG. 2 shows a partial view of FIG. 1 of a further embodiment .

Das Fahrzeug 1 weist einen Boden 2 auf, der einen Sitz trägt. Zwischen Sitz 3 und Boden 2 ist ein Hebelparallelogramm 4 und ein hydraulisches Verdrängerelement 5 vorgesehen, das Bestand teil eines hydropneumatisehen Federungssystems 6 ist. Das Federungssystem 6, das über eine Leitung 7 mit dem Verdrängerelement 5 verbunden ist, weist einen Hydraulikraum 8 und einen Gasraum 9 auf, die durch eine Membran 10 getrennt sind.The vehicle 1 has a floor 2 which carries a seat. Between seat 3 and floor 2 is a lever parallelogram 4 and a hydraulic displacement element 5 is provided, which is part of a hydropneumatic suspension system 6. That Suspension system 6, which via a line 7 with the displacement element 5, has a hydraulic space 8 and a gas space 9, which are separated by a membrane 10.

Im hinteren Bereich des Bodens 2 ist ein sich in Fahrzeuglängsrichtung erstreckendes Führungsglied 11 für ein Rad 12 vorgesehen. Das Führungsglied 11 stützt sich an einer nicht gezeigten Drehstabfeder und einem Stoßdämpfer 13 ab.In the rear area of the floor 2 there is a longitudinal direction of the vehicle extending guide member 11 for a wheel 12 intended. The guide member 11 is not supported on one torsion bar spring shown and a shock absorber 13 from.

Zwischen Radführungsglied 11 und einer Wand 14 des Bodens 2 ist eine Kolben-Zylinder-Einheit 15, bestehend aus Kolben 16 und Zylinder 17, vorgesehen. Ferner umfasst sie einen Regelraum 18, der über eine einen elastischen Abschnitt 19 aufweisende Leitung 20 mit der Hydraulikseite verbunden ist.Between the wheel guide member 11 and a wall 14 of the floor 2 is a piston-cylinder unit 15, consisting of piston 16 and cylinder 17 are provided. Furthermore, it comprises a control space 18, which has an elastic section 19 Line 20 is connected to the hydraulic side.

überfährt das Fahrzeug 1 eine Bodenunebenheit 21, wird das Rad 12 nach oben beschleunigt und drückt über das Führungsglied 11 den Kolben 15 in Richtung A. Hierdurch wird Druck- If the vehicle 1 drives over a bump in the ground 21, it will Wheel 12 accelerates upwards and pushes piston 15 in direction A via guide member 11.
