Description
Die Erfindung betrifft ein aktives Fahrwerk für ein Kraftfahrzeug mit mindestens einer ersten und einer zweiten Radaufhängungseinrichtung für jeweils zwei sich gegenüberliegende Räder nach dem Oberbegriff des ersten Anspruchs.The The invention relates to an active chassis for a motor vehicle with at least a first and a second suspension device for each two opposite wheels according to the preamble of the first claim.

bekannt, der zwei Räder einer Fahrzeugachslinie koppelt
und der aus einem dem einen Rad zugeordneten ersten Stabilisatorteil
und aus einem dem anderen Rad zugeordneten zweiten Stabilisatorteil,
sowie aus einem die Stabilisatorteile koppelnden Aktuator besteht.
Der Aktuator steuert die Seitenneigung des Kraftfahrzeugs durch

Aktive Fahrwerke mit zwei Aktuatoren stellen einen guten Funktionskompromiss dar. Sollen zusätzliche Funktionen erfüllt werden, müssen nach dem Stand der Technik weitere Systeme, wie Verstelldämpfung oder Luftfederung, kombiniert werden.active Suspensions with two actuators provide a good functional compromise dar. Additional functions are fulfilled, must according to the state of the art other systems, such as Adjustable damping or air suspension, combined.
Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden. Ohne Einbindung weiterer Systeme sollen weitere Funktionen mit einem aktiven Fahrwerk nach der Erfindung erfüllbar sein.task The invention is to avoid these disadvantages. Without involvement Other systems should have additional functions with an active chassis be fulfilled according to the invention.
Die Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The The object is achieved with the features of claim 1. Further embodiments of the invention will become apparent from the dependent claims.
Nach der Erfindung ist ein Fahrwerk für ein Kraftfahrzeug, mit mindestens einer ersten und einer zweiten Radaufhängungseinrichtung für jeweils zwei sich gegenüberliegende Räder, dadurch gekennzeichnet, dass jedes Rad der ersten Radaufhängungseinrichtung über ein Element mit Drehfedereigenschaften mit einer Karosserie des Kraftfahrzeugs verbunden ist, wobei an jedem Element mit Drehfedereigenschaften mindestens ein Aktuator zur Niveauänderung des Kraftfahrzeugs angreift und dass die Räder der zweiten Radaufhängungseinrichtung, durch einen geteilten Stabilisator mit einem eingebauten weiteren Aktuator, zur Verdrehung der beiden Stabilisatorteile gegeneinander, verbunden sind.To The invention is a chassis for a motor vehicle, with at least one first and one second suspension device for each two opposing wheels, characterized in that each wheel of the first suspension means via an element with torsion spring properties with a body of Motor vehicle is connected, wherein on each element with torsion spring properties at least one actuator for level change of the motor vehicle engages and that the wheels of the second suspension device, through a split stabilizer with a built-in additional actuator, for rotating the two stabilizer parts against each other, connected are.
Das hat den Vorteil, dass durch drei Aktuatoren neben dem Wank- und Nickausgleich auch noch ein Beladungsausgleich übernommen werden kann. Eine Verstelldämpfung an der Hinterachse kann dadurch zusätzlich entfallen, ebenso wie ein Beladungsausgleich mittels einer Hinterachsluftfederung.The has the advantage that by three actuators in addition to the roll and Nick compensation also added a load compensation can be. A damping at the rear axle can This additionally eliminates, as well as a load compensation by means of a rear axle air suspension.
Idealerweise sind die Aktuatoren elektromechanische Rotationssteller, mindestens bestehend aus Elektromotor und Getriebe.Ideally the actuators are electromechanical rotation actuators, at least consisting of electric motor and gearbox.
Bevorzugte Ausführungen der Erfindung sind dadurch gekennzeichnet, dass die erste Radaufhängungseinrichtung an einer Hinterachse und die zweite Radaufhängungseinrichtung an einer Vorderachse des Kraftfahrzeugs montiert ist. Dabei kann der weitere Aktuator als Schwenkmotor ausgebildet sein und mindestens aus einem Verstellantrieb aus Elektromotor und Schwenkmotorgetriebe und aus einem Gehäuse bestehen und die beiden Elemente mit Drehfedereigenschaften können über ihre Aktuatoren, insbesondere in etwa mittig, mit der Karosserie verbunden sein.preferred Embodiments of the invention are characterized that the first suspension device on a rear axle and the second suspension device on a front axle of the motor vehicle is mounted. In this case, the further actuator be designed as a swivel motor and at least one adjustment from electric motor and swivel motor gearbox and from a housing exist and the two elements with torsion spring properties can over their actuators, in particular in the middle, connected to the body be.
Besonders vorteilhaft ist es, wenn sich die beiden Elemente mit Drehfedereigenschaften über die gesamte Breite zwischen den beiden aufzuhängenden Rädern erstrecken, wodurch jedes Element bei gleicher Belastung um einen größeren Weg ausgelenkt werden kann und somit die Unterdrückung der Wankbewegung weicher gestaltet werden und feiner abgestimmt werden kann. Die Lebensdauer der Elemente mit Drehfedereigenschaften kann dadurch erhöht werden. Außerdem ergeben sich größere Freiheiten für die Anordnung der Elemente mit Drehfedereigenschaften im Fahrzeug.Especially It is advantageous if the two elements with torsion spring properties on the entire width between the two wheels to be suspended extend, whereby each element at the same load by one larger way can be deflected and thus the suppression of the rolling motion be made softer and fine tuned. The life of the elements with torsion spring properties can be increased thereby. In addition, greater freedom results for the arrangement of elements with torsion spring properties in the vehicle.
Zur aktiven Regelung ist vorteilhafterweise jeder Aktuator mit einer Steuer- oder Regeleinrichtung verbunden, die als Ausgangsgrößen Stellsignale für die Aktuatoren erzeugt. Dabei ist die Steuer- oder Regeleinrichtung mit Sensoren, insbesondere mit mindestens einem Höhensensor und/oder einem Geschwindigkeitssensor und/oder einem Beschleunigungssensor, verbunden, deren Messwerte Eingangsgrößen für die Steuer- bzw. Regeleinrichtung sind. So kann die Steuer- oder Regeleinrichtung durch eine entsprechende Ansteuerung der Aktuatoren einen Nickausgleich und/oder einen Wankausgleich und/oder eine Niveauregelung des Kraftfahrzeugs bewirken.to Active control is advantageously each actuator with a Control or regulating device connected as output variables Actuator signals generated for the actuators. It is the Control or regulating device with sensors, in particular with at least a height sensor and / or a speed sensor and / or an acceleration sensor, whose measured values are connected Input variables for the control or regulating device are. Thus, the control or regulating device by a corresponding Actuation of the actuators Nick compensation and / or roll compensation and / or effect a level control of the motor vehicle.
