Abstract

The hydraulic stabiliser consists of a piston cylinder unit (1,3') (2,4) fitted between both a left and right wheel and the vehicle chassis. The piston (1,3) separates two fluid cylinder chambers (11,14;) (12,15). The upper chamber (12) of the left cylinder (1) is connected to the lower (14) of the right (3) and vice versa (11) to (15). A compensation chamber (5,6) is fitted in each of the connecting lines. Pref. the compensation chamber has a gas damping cushion (9,10) and or coil spring (19,20) separate from the hydraulic fluid line. Pref. the gas cushion and or coil spring are matched to the system pressure and the stabiliser characteristics.

Description

Das Hydraulikelement "rechtes Rad" ist mit der Kolbenstange (1) am Radträger bzw. Quer-/Längslenker befestigt und mit dem Gehäuse (3) am Chassis befestigt. Das Hydraulikelement "linkes Rad" ist mit der Kolbenstange (2) am Radträger bzw. Quer-/Längslenker befestigt und mit dem Gehäuse (4) am Chassis befestigt.The hydraulic element "right wheel" is attached to the wheel carrier or wishbone / trailing arm with the piston rod ( 1 ) and attached to the chassis with the housing ( 3 ). The hydraulic element "left wheel" is attached to the wheel carrier or wishbone / trailing arm with the piston rod ( 2 ) and attached to the chassis with the housing ( 4 ).

Die Gaskammern (9) und (10) sind mit einem Grundsystemdruck vorgespannt.The gas chambers ( 9 ) and ( 10 ) are biased with a basic system pressure.

Federt nun das rechte Rad gleich wie das linke Rad ein, so strömt das Öl aus der Kammer (11) in die Kammer (15) und das Öl aus der Kammer (12) in die Kammer (14). In den Kammern (13) und (16) ändert sich das Volumen nicht; also bleibt der Gasdruck in den Kammern (9) und (10) gleich.If the right wheel springs in the same way as the left wheel, the oil flows from the chamber ( 11 ) into the chamber ( 15 ) and the oil from the chamber ( 12 ) into the chamber ( 14 ). The volume does not change in the chambers ( 13 ) and ( 16 ); so the gas pressure in chambers ( 9 ) and ( 10 ) remains the same.

Das bedeutet, daß bei gleichen Wegen rechts/links der Öldruck über und unter den Kolben (17) und (18) gleich bleibt und somit keine Kraft erzeugt wird.This means that with the same paths on the right / left, the oil pressure above and below the pistons ( 17 ) and ( 18 ) remains the same and therefore no force is generated.

Das gleiche Prinzip gilt auch, wenn das rechte und linke Rad gleich ausfedern.The same principle applies if the right and left wheels rebound equally.

Federt aber das rechte Rad ein und das linke Rad aus, so strömt das Öl aus der Kammer (11) und der Kammer (15) in die Kammer (16). Dort wird das Gasvolumen (10) komprimiert. In die Kammer (14) und die Kammer (12) muß Öl der Kammer (13) strömen. Deshalb wird das Gasvolumen (9) entspannt.If the right wheel springs in and the left wheel springs out, the oil flows from the chamber ( 11 ) and the chamber ( 15 ) into the chamber ( 16 ). The gas volume ( 10 ) is compressed there. Oil from the chamber ( 13 ) must flow into the chamber ( 14 ) and the chamber ( 12 ). The gas volume ( 9 ) is therefore released.

Durch die unterschiedlichen Gasdrücke und den damit verbundenen Öldrücken über und unter den Kolben (17) und (18) wird nun jeweils eine Kraft im rechten und linken Rad entgegen der jeweiligen Bewegungsrichtung erzeugt.Due to the different gas pressures and the associated oil pressures above and below the pistons ( 17 ) and ( 18 ), a force is now generated in the right and left wheel against the respective direction of movement.

Das gleiche Prinzip gilt auch, wenn das rechte Rad aus- und das linke Rad einfedern.The same principle applies if the right wheel springs out and the left wheel springs in.

Das Ölvolumen der Kammern (11), (15) und (16) ist mittels der Kolben (17) und (18) vom Ölvolumen der Kammern (12), (13) und (14) getrennt.The oil volume of the chambers ( 11 ), ( 15 ) and ( 16 ) is separated from the oil volume of the chambers ( 12 ), ( 13 ) and ( 14 ) by means of the pistons ( 17 ) and ( 18 ).

Die Kammern (11), (15) und (16) sind miteinander mittels Leitungen verbunden. Ebenso die Kammern (12), (13) und (14).The chambers ( 11 ), ( 15 ) and ( 16 ) are connected to one another by means of lines. The same applies to chambers ( 12 ), ( 13 ) and ( 14 ).

Das Gasvolumen (9) ist vom Ölvolumen (13) mittels des Kolbens (7) getrennt. Ebenso das Gasvolumen (10) vom Ölvolumen (16) durch den Kolben (8).The gas volume ( 9 ) is separated from the oil volume ( 13 ) by means of the piston ( 7 ). Likewise the gas volume ( 10 ) from the oil volume ( 16 ) through the piston ( 8 ).

Mittels verschiedener Gasvolumen, Gasgrunddrücken und unterstützender Federn (19) und (20) können verschiedene Stabilisatorenkennlinien erzeugt werden.Different stabilizer characteristics can be generated using different gas volumes, basic gas pressures and supporting springs ( 19 ) and ( 20 ).

Vereinfachend kann gesagt werden, daß der hydraulische Stabilisator bei gleichen Wegen rechts/links kraftlos bleibt, jedoch bei Wegdifferenzen eine rückstellende Kraft erzeugt. Das System arbeitet rein wegabhängig.To simplify it can be said that the hydraulic stabilizer with the same paths right / left remains without power, but generates a restoring force when there are path differences. The System works purely path-dependent.
