Abstract

Each vehicle wheel (2,3) is connected to the body (4) via a suspension system and an active hydraulic or mechanical stabilizer. The pressure-medium suspension system of both sides are connected by a conduit (38) containing a moveable transfer medium. With a pure rolling motion of the vehicle, only transfer medium is moved in the conduit but there is no suspension effect, and the suspension system does not form part of the overall rolling motion stiffness of the appliance. The missing component is compensated for by increasing the stiffness of the active stabilizer to achieve the required passive overall rolling motion stiffness.

Description

Die Erfindung betrifft eine Vorrichtung zur Federung und Wankstabilisierung von Kraftfahrzeugen nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a device for suspension and roll stabilization of motor vehicles according to the im The preamble of claim 1 defined in more detail.

Zur Erhöhung der Wanksteifigkeit von Fahrzeugen werden Stabilisatoren verwendet, die hydraulisch oder mechanisch sein können. Bei Verwendung von mechanischen Stabilisatoren kommt es zu einer ungleichen Belastung der kurveninneren und -äußeren Räder, was zu einem instabilen Fahrverhalten führt. Der aus der DE-OS 19 47 232 bekannte hydropneumati­ sche Stoßdämpfer mit zusätzlichen Gasdruckspeichern zeigt eine Überkreuzverbindung der beiden Achsseiten, wodurch eine wirkungsvollere Verringerung der Aufbauüberneigung erreicht werden kann.To increase the roll stiffness of vehicles Stabilizers used hydraulically or mechanically could be. When using mechanical stabilizers there is an uneven load on the inside of the curve and outer wheels, resulting in unstable driving behavior leads. The hydropneumati known from DE-OS 19 47 232 shows shock absorbers with additional gas pressure accumulators a cross connection of the two axle sides, whereby a more effective reduction in propensity to build can be achieved.

Die Gesamtwanksteifigkeit eines Fahrzeugs setzt sich aus einem Anteil, der durch die Aufbaufederung in Verbin­ dung mit der Spurweite gebildet wird und einem Stabilisa­ toranteil zusammen.The overall roll stiffness of a vehicle sets from a share that is due to the body suspension in connection is formed with the gauge and a Stabilisa share of goals.

Der aktive Eingriff an einem Stabilisator zum Zwecke einer Wankstabilisierung des Fahrzeugaufbaus ist sowohl bei mechanischen als auch bei hydraulischen Stabilisatoren mög­ lich.The active intervention on a stabilizer for the purpose roll stabilization of the vehicle body is both mechanical as well as hydraulic stabilizers possible Lich.

Bei diesen Vorrichtungen wirkt sich jedoch nachteilig aus, daß der aktive Stabilisator gegen die von den Aufbaufedern gebildete Wanksteifigkeit arbeitet und somit viel Energie verbraucht wird. However, these devices have a disadvantageous effect, that the active stabilizer against that of the body springs formed roll stiffness works and thus a lot of energy is consumed.  

In der EP 536 707 A1 wurde dieser Nachteil des hohen Ener­ gieverbrauchs durch eine mittige Anordnung von nur einer Gasfeder pro Achse umgangen, da die mittige Gasfeder keinen Anteil an der Gesamtwanksteifigkeit des Fahrzeugs hat. Nachteilig an dieser Vorrichtung ist jedoch der benötigte Einbauraum und die damit verbundene Einschränkung der Bo­ denfreiheit in einem konventionellen Fahrzeug.In EP 536 707 A1 this disadvantage of the high energy energy consumption thanks to a central arrangement of just one Gas spring bypassed per axis, since the central gas spring has none Has a share in the overall stiffness of the vehicle. However, the disadvantage of this device is that which is required Installation space and the associated restriction of the Bo freedom in a conventional vehicle.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Federung und Wankstabilisierung von Kraftfahrzeugen darzustellen, bei dem ein oder mehrere ak­ tive mechanische oder hydraulische Stabilisatoren verwendet werden können, um eine aktive Wankstabilisierung des Auf­ baus zu erreichen. Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, den Energieverbrauch einer solchen Vorrichtung durch gezielte Trennung der Aufgaben Wank- und Hubsteifigkeit zu verringern.The present invention is based on the object a device for suspension and roll stabilization of To represent motor vehicles in which one or more ak tive mechanical or hydraulic stabilizers used can be an active roll stabilization of the on to reach construction. Another task of the present Invention is the energy consumption of such Device by deliberately separating the tasks Wank and Reduce lifting rigidity.

Die der Erfindung zugrunde liegende Aufgabe wird durch eine, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisende, gattungsgemäße Federungs- und Wankstabilisie­ rungsvorrichtung gelöst.The object underlying the invention is achieved by one, also the characteristic features of the main claim having generic suspension and roll stabilization tion device solved.

Durch die Verwendung eines gasförmigen oder flüssigen Federungs- bzw. Kraftübertragungsmediums wird bei einer reinen Wankbewegung lediglich das Medium in einer Verbin­ dungsleitung verschoben, aber keine Federwirkung ausgeübt. Die Aufbaufederung erbringt damit die gesamte Hubsteifig­ keit des Fahrzeuges, aber keine Wanksteifigkeit, während die aktiven Stabilisatoren dagegen die gesamte Wanksteifig­ keit, aber keine Hubsteifigkeit erbringen.By using a gaseous or liquid Suspension or power transmission medium is at a pure roll motion only the medium in a verb cable moved, but no spring effect. The body suspension thus provides the entire lifting rigidity speed of the vehicle, but no stiffness during the active stabilizers, on the other hand, make the entire roll stiff speed, but do not provide any rigidity.

Durch die Aufteilung der Aufgaben kann der Energieverbrauch der Vorrichtung deutlich reduziert werden. By dividing the tasks, the energy consumption the device can be significantly reduced.

Anstelle der Fahrzeugräder 2 und 3 kann auch eine Zwillingsbereifung und anstelle der Starrachse jede weitere Radaufhängung vorgesehen werden. Die Verbin­ dung der Starrachse 1 mit einem Karosserieaufbau 4 erfolgt mittels achsseitiger Gelenke 8, 10, 13, 14 und aufbauseiti­ ger Gelenke 41, 42, 43, 44 über zwei Doppelkammerzylinder 5 und 6 und zwei Federzylinder 11 und 12. Der Doppelkammerzy­ linder 5 ist mit einer Kolbenstange 7 in dem Gelenk 8 an der Starrachse 1 angelenkt. Analog hierzu greift eine Kol­ benstange 9 des Doppelkammerzylinders 6 in dem Gelenk 10 der Starrachse 1 an.In Fig. 1 as a first advantageous embodiment of the invention, a device consisting of a hydraulic stabilizer and a hydropneumatic suspension, for suspension and roll stabilization with a rigid axle 1 and vehicle wheels 2 and 3 attached to it. Instead of the vehicle wheels 2 and 3 , twin tires and any other wheel suspension instead of the rigid axle can also be provided. The connec tion of the rigid axle 1 with a body structure 4 takes place by means of axle joints 8 , 10 , 13 , 14 and aufbaueiti ger joints 41 , 42 , 43 , 44 via two double chamber cylinders 5 and 6 and two spring cylinders 11 and 12 . The Doppelkammerzy cylinder 5 is articulated with a piston rod 7 in the joint 8 on the rigid axle 1 . Analogously, a Kol engages rod 9 of the double chamber cylinder 6 in the joint 10 of the rigid axle 1 .

Jeder der Doppelkammerzylinder 5 und 6 weist zwei Zylinder­ räume 15 und 16 sowie 17 und 18 auf. Die Zylinderräume 15 und 16 sind durch einen Trennkolben 21, die Zylinderräu­ me 17 und 18 durch einen Trennkolben 22 voneinander ge­ trennt. Eine Leitung 25 verbindet den Zylinderraum 15 des Doppelkammerzylinders 5 mit dem Zylinderraum 18 des Doppel­ kammerzylinders 6. In gleicher Weise verbindet eine Lei­ tung 26 den Zylinderraum 16 mit dem Zylinderraum 17. Durch die Leitungen 25 und 26 sind die Doppelkammerzylinder über Kreuz miteinander verschaltet.Each of the double chamber cylinders 5 and 6 has two cylinder chambers 15 and 16 and 17 and 18 . The cylinder chambers 15 and 16 are separated by a separating piston 21 , the cylinder chambers 17 and 18 from each other by a separating piston 22 . A line 25 connects the cylinder chamber 15 of the double chamber cylinder 5 with the cylinder chamber 18 of the double chamber cylinder 6 . In the same way, a Lei device 26 connects the cylinder chamber 16 with the cylinder chamber 17th The double-chamber cylinders are cross-connected to one another through lines 25 and 26 .

An jede der Leitungen 25 und 26 ist über Anschlußleitun­ gen 27 und 28 ein Speicher 29 und 30 angeschlossen. In den Anschlußleitungen 27 und 28 sind Dämpfungselemente 31 und 32 angebracht, die zusätzlich Wankbewegungen abschwä­ chen. Zur aktiven Wankstabilisierung werden die Doppelkam­ merzylinder 5 und 6 durch einen Aktuator 33, der über An­ schlußleitungen 45 und 46 an die Leitungen 25 und 26 gekop­ pelt ist, mit Druck beaufschlagt.To each of the lines 25 and 26 , a memory 29 and 30 is connected via connecting lines 27 and 28 . In the connecting lines 27 and 28 , damping elements 31 and 32 are attached, which additionally weaken roll movements. For active roll stabilization, the Doppelkam mer cylinder 5 and 6 are acted upon by an actuator 33 , which is connected via connecting lines 45 and 46 to lines 25 and 26 , with pressure.

Der Aktuator 33 verschiebt Medium von einer Fahrzeugseite zur anderen, wodurch die Wankstabilisierung realisiert wird.The actuator 33 shifts medium from one side of the vehicle to the other, thereby realizing the roll stabilization.

A cylinder chamber 19 of the spring cylinder 11 is connected via a Lei device 38 with a cylinder chamber 20 of the spring cylinder 12 .

Eine Leitung 47 verbindet den Zylinderraum 19 des Federzy­ linders 11 über ein Dämpfungselement 36 mit einem weiteren Speicher 34. Analog dazu ist der Zylinderraum 20 des Feder­ zylinders 12 über eine Leitung 48, in der ein Dämpfungsele­ ment 37 integriert ist, mit einem Speicher 35 verbunden. Die Federzylinder 11 und 12 der hydropneumatischen Federung sind also über die Leitung 38 kurzgeschlossen und bewerk­ stelligen die Federung des Aufbaus 4.A line 47 connects the cylinder chamber 19 of the Federzy Linders 11 via a damping element 36 with a further memory 34th Analogously, the cylinder chamber 20 of the spring cylinder 12 is connected to a memory 35 via a line 48 , in which a damping element 37 is integrated.
