Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betrieb einer Sicherheitseinrichtung für einen verstellbaren Stabilisators gemäß dem Oberbegriff von Patentanspruch 1.The The invention relates to a method for operating a safety device for an adjustable stabilizer according to The preamble of claim 1.
Ein verstellbarer Stabilisator umfasst in der Regel zwei Stabilisatorabschnitte, die jeweils mit einem Rad in Wirkverbindung stehen. Zwischen den Stabilisatorabschnitten ist eine Torsionserzeugungseinrichtung, z. B. ein Schwenkmotor angeordnet, der die beiden Stabilisatorabschnitte um die Längsachse der Stabilisatorabschnitte verspannt. Der Schwenkmotor wird beispielsweise elektrisch oder hydraulisch betrieben. Im Fall einer Unterbrechung der Energieversorgung des Schwenkmotors können sich beide Stabilisatorabschnitte nahezu vorspannungsfrei zueinander verdrehen, so dass für einen Fahrzeugaufbau kein Abstützmoment zur Verfügung steht. Bei hydraulischen Schwenkmotoren lässt sich dieser Notfall vergleichsweise leicht beheben, indem z. B. Sperrventile verwendet werden, die den Schwenkmotor vom Hydrauliksystem vollständig abkoppeln und zumindest eine Wirkung vergleichbar einem konventionellen Stabilisator erreichbar ist.One adjustable stabilizer usually comprises two stabilizer sections, each in operative connection with a wheel. Between the stabilizer sections is a torsion generator, z. B. a pivot motor arranged, the two stabilizer sections about the longitudinal axis of Stabilizer sections clamped. The swivel motor, for example operated electrically or hydraulically. In case of interruption The power supply of the slew motor can be both stabilizer sections twist almost without bias to each other, so for a vehicle body no support torque available stands. With hydraulic swivel motors this can be Resolve emergency relatively easily by z. B. check valves be used, the swing motor from the hydraulic system completely decouple and at least one effect comparable to a conventional one Stabilizer is achievable.

elektrisch betriebene Stabilisatoren ist es z. B. aus der

Die
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zum Betrieb einer Sicherheitseinrichtung für einen verstellbaren Stabilisator bereitzustellen, wobei der verstellbare Stabilisator einen möglichst einfachen Aufbau aufweisen soll.The The object of the present invention is a method for operating a safety device for an adjustable Stabilizer provide, wherein the adjustable stabilizer should have the simplest possible structure.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Sicherheitseinrichtung von dämpfkraftverstellbaren Schwingungsdämpfern gebildet wird, die zusätzlich zum verstellbaren Stabilisator im Fahrwerk angeordnet sind, wobei die Schwingungsdämpfer bei Ausfall des verstellbaren Stabilisators auf eine größere Dämpft eingestellt werden.According to the invention the object achieved in that the safety device of damping force adjustable vibration dampers is formed, in addition to the adjustable stabilizer are arranged in the chassis, with the vibration damper in case of failure of the adjustable stabilizer on a larger Damping be adjusted.
Die unabhängig von der Torsionserzeugungseinrichtung wirksamen verstellbaren Dämpfer ermöglichen einen vereinfachten Aufbau der Torsionserzeugungseinrichtung, so dass Bauraumprobleme für den verstellbaren Stabilisator zumindest entschärft werden. Im Vergleich zu einer mechanischen Bremse ist der Einsatz der verstellbaren Schwingungsdämpfer nicht als Ruck im Fahrzeugaufbau spürbar.The independent of the torsion generator effective adjustable dampers allow a simplified Structure of the torsion generating device, so that space problems at least defused for the adjustable stabilizer become. Compared to a mechanical brake is the use the adjustable vibration damper not as jerk in Vehicle structure noticeable.
In weiterer vorteilhafter Ausgestaltung wird der Steuerung für die verstellbaren Schwingungsdämpfer ein Energiezustandssignal des verstellbaren Stabilisators zugeführt.In Another advantageous embodiment of the controller for the adjustable vibration damper an energy condition signal fed to the adjustable stabilizer.
Des Weiteren ist vorgesehen, dass die dämpfkraftverstellbaren Schwingungsdämpfer in Ein- und in Ausfederungsrichtung getrennt verstellbare Dämpfventile aufweisen, die bei Ausfall des verstellbaren Stabilisators gegenläufig verstellt werden. Der Vorteil dieser Maßnahme besteht darin, dass der Fahrzeugaufbau nicht einfach durch eine einfache Verstellung der Schwingungsdämpfer auf eine harte Kennlinie abgestützt wird, sondern durch gezielte Stützkräfte eine Schieflage des Fahrzeugaufbaus korrigiert werden kann.Of Furthermore, it is provided that the damping force adjustable Vibration damper in in and out direction have separately adjustable damping valves, which in case of failure of the adjustable stabilizer are adjusted in opposite directions. The advantage of this measure is that the vehicle body not simply by a simple adjustment of the vibration damper is based on a hard characteristic, but by targeted support forces corrects an imbalance of the vehicle body can be.
