Die erfindungsgemäße Radaufhängungsvorrichtung für Motorräder weist an der Vorderachse und an der Hinterachse mindestens eine Aufhängungseinheit zwischen Rad und Motorradrahmen auf, bei der die Dämpfungskraft und/oder die Federkraft mittels eines elektronischen Steuergerätes abhängig von einer manuell verstellbaren Auswahleinheit und/oder abhängig von erfaßten Betriebsparametern automatisch verstellbar sind. Die Aufhängungseinheit weist im Unterschied zu einer hydraulischen oder pneumatischen Verstellvorrichtung eine elektromechanische Verstellvorrichtung auf, die mittels des elektronischen Steuergeräts betätigt werden kann. Vorzugsweise umfaßt die elektromechanische Verstellvorrichtung der Aufhängungseinheit zur Verstellung der Dämpfungskraft und/oder der Federkraft einen Schrittmotor. Alternativ kann insbesondere für die Verstellung der Dämpfungskraft die elektromechanische Verstellvorrichtung der Aufhängungseinheit auch ein Piezoelement umfassen.The wheel suspension device according to the invention for motorcycles instructsat least one suspension on the front axle and on the rear axlebetween the wheel and the motorcycle frame, where the damping forceand / or the spring force is dependent on an electronic control unitfrom a manually adjustable selection unit and / or depending on itoperating parameters are automatically adjustable. The suspensionunlike a hydraulic or pneumatic unitAdjustment device on an electromechanical adjustment device, thecan be operated by means of the electronic control unit. Preferablycomprises the electromechanical adjustment device of the suspension unitto adjust the damping force and / or the spring force one stepengine. Alternatively, in particular for the adjustment of the damping forcethe electromechanical adjustment device of the suspension unit alsoInclude piezo element.
Bei herkömmlichen Radaufhängungssystemen ohne elektronische Steuerung sind mechanische Verstellvorrichtungen in Form von manuell verstellbaren Schrauben an der Aufhängungseinheit bekannt. Derartige Aufhängungseinheiten sind für die Erfindung verwendbar, wenn z. B. die ohnehin vorhandene mechanische Verstellvorrichtung mit einem Elektroantrieb, wie z. B. einem Schrittmotor oder einem Piezoelement, verbunden wird.With conventional suspension systems without electronic controltion are mechanical adjustment devices in the form of manual adjustmentble screws on the suspension unit known. Such hangerssupply units can be used for the invention if, for. B. the anywayexisting mechanical adjustment device with an electric drive, such ase.g. B. a stepper motor or a piezo element.
Hierdurch wird auf einfache Weise ein mittels eines elektronischen Steuergeräts betätigbare elektromechanische Verstelleinrichtung geschaffen. Durch diese Erfindung sind keine aufwendigen systemabhängigen Aufhängungseinheiten erforderlich. Motorräder mit rein mechanischer Verstellvorrichtung könnten sogar auf einfache Weise nachgerüstet werden.This is a simple means of an electronic SteuergeElectromechanical adjustment device operated by devices. Bythis invention is not a complex, system-dependent suspensionunits required. Motorcycles with purely mechanical adjustment devicescould even be easily upgraded.
Bisher wurde der Fachmann davon abgehalten andere als hydraulische Verstellvorrichtungen für elektronisch gesteuerte Radaufhängungsvorrichtungen zu verwenden; denn derartige Systeme sind den Regelsystemen bei Personenkraftfahrzeugen entnommen. Bei Personenkraftfahrzeugen führt höheres Gewicht und größerer Bauraum nicht zu den Problemen, die bei Motorrädern vorherrschen. Zwar sind die elektromechanischen Verstellvorrichtungen langsamer als hydraulische Verstellvorrichtungen, jedoch wird in diesem Zusammenhang erfindungsgemäß vorzugsweise auch eine Funktionsvereinfachung vorgenommen. Beispielsweise wird keine Berücksichtigung von sich sehr schnell ändernden Betriebsparametern, wie z. B. der Radhub abhängig von Fahrbahnunebenheiten, vorgenommen. Insbesondere werden erfindungsgemäß sich langsamer ändernde Betriebsparameter, wie z. B. die Geschwindigkeit, die Beschleunigung bzw. die Verzögerung, ein Bremsvorgang oder die Beladung, berücksichtigt.So far, the expert has been prevented from other than hydraulic VerActuators for electronically controlled suspension devicesto use; because such systems are the control systems at Persotaken from motor vehicles. In passenger cars, higher resultsWeight and larger installation space are not one of the problems with motorcyclesprevalence. The electromechanical adjustment devices are indeedslower than hydraulic adjustment devices, however, this willconnection according to the invention preferably also a functional simplificationmade. For example, no consideration of itselfvery quickly changing operating parameters, such as B. the wheel stroke dependentof road bumps. In particular, are inventedaccording to slower changing operating parameters such. B. the Gespeed, acceleration or deceleration, brakingor the load.
Die manuell verstellbare Auswahleinheit hat in einer Weiterbildung der Erfindung zwei Auswahlmöglichkeiten:
In a further development of the invention, the manually adjustable selection unit has two selection options:
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Sie zeigt schematisch eine erfindungsgemäße Radaufhängungsvorrichtung in Verbindung mit einem elektronischen Steuergerät und einem Bordcomputer als Auswahleinheit für zwei Auswahlmöglichkeiten.In the drawing, an embodiment of the invention is shown. sheschematically shows a wheel suspension device according to the invention inConnection to an electronic control unit and an on-board computeras a selection unit for two selection options.
In der Zeichnung sind eine Aufhängungseinheit1 an der Vorderachse, im ff. vorderes Federbein1 genannt, und eine hintere Aufhängungseinheit2 an der Hinterachse, im ff. hinteres Federbein2 genannt, dargestellt. Das vordere Federbein1 weist ein Piezoelement3 zur Verstellung der Dämpfungskraft (Dv) vorne auf. Das hintere Federbein2 weist einen Schrittmotor4 zur Verstellung der Dämpfungskraft (Dh) und einen Schrittmotor5 zur Verstellung der Federkraft (Fh) hinten auf.In the drawing, a suspension unit1 on the front axle, called the front strut1 in the ff., And a rear suspension unit2 on the rear axle, called the rear strut2 in the ff. The front strut1 has a piezo element3 for adjusting the damping force (Dv) on the front. The rear strut2 has a stepper motor4 for adjusting the damping force (Dh) and a stepper motor5 for adjusting the spring force (Fh) at the rear.
Die elektromechanischen Verstellvorrichtungen3 bis5 sind über Steuerleitungen mit einem elektronischen Steuergerät6 verbunden. Mittels des elektronischen Steuergeräts6 können die einstellbaren Kräfte (Dv, Dh, Fh) an den Federbeinen1 und2 entweder gesteuert oder geregelt werden.The electromechanical adjustment devices3 to5 are connected to an electronic control unit6 via control lines. By means of the electronic control unit6 , the adjustable forces (Dv, Dh, Fh) on the struts1 and2 can either be controlled or regulated.
Die Einstellung der Kräfte (Dv, Dh, Fh) an den Federbeinen1 und2 durch das Steuergerät6 erfolgt in Abhängigkeit von den Signalen einer Auswahleinheit7 in Form eines Bordcomputers, der mit dem Steuergerät6 verbunden ist, und/oder in Abhängigkeit von Betriebsparametern, insbesondere der Beladung m, der Geschwindigkeit v und der Bremsbetätigung B.The setting of the forces (Dv, Dh, Fh) on the struts1 and2 by the control unit6 takes place in dependence on the signals of a selection unit7 in the form of an on-board computer which is connected to the control unit6 and / or in dependence of operating parameters, in particular the loading m, the speed v and the brake actuation B.
Der Bordcomputer7 weist ein Display8 und ein Bedienfeld9 auf. Die Bezugszeichen10 bis14 sind beispielsweise die Anzeigeschritte bei einem Menüdurchlauf des Bordcomputers7.The on-board computer7 has a display8 and a control panel9 . The reference numerals10 to14 are, for example, the display steps when the on-board computer7 runs through the menu.
Der Fahrer hat die erste Auswahlmöglichkeit, über das Display8 im Modus A eine Vorauswahl, z. B. "S" (Sport), "N" (Normal) oder "K" (Komfort), manuell zu treffen. Abhängig von dieser Vorauswahl und von den Betriebsparametern m, v, B verstellt das Steuergerät6 automatisch mittels abgespeicherter Kennfelder die Verstellvorrichtungen3 bis5 der Federbeine1 und2. Beispielsweise erkennt das System die Beladung m aufgrund des Einfederungszustandes an der Hinterradführung und regelt diese zu Beginn der Fahrt auf eine definierte Nullage (integrierte Fahrzeughöhensteuerungsfunktion). Die Dämpfungskraft (Dh, Dv) und/oder die Federkraft (Fh) wird anschließend diesem Beladungszustand angepaßt; die entsprechenden Einstellungen der Verstellvorrichtungen3 bis5 sind in einem Kennfeld hinterlegt. Zusätzlich werden die Dämpfungskräfte (Dv, Dh) und/oder die Federkraft (Fh) dem aktuellen Fahrzustand abhängig von der Geschwindigkeit v, der Beschleunigung (dv/dt) oder dem Bremsvorgang B dynamisch angepaßt. Das System verhindert vorzugsweise durch Erkennen der Geschwindigkeit v, daß im fahrdynamisch kritischen Hochgeschwindigkeitsbereich ohne ausreichende Dämpfungskraft (Dv, Dh) gefahren wird. Umgekehrt wird bei sehr niedrigen Geschwindigkeiten v die Dämpfungskraft (Dv, Dh) automatisch hinsichtlich Komfort verstellt.The driver has the first option of making a preselection via the display8 in mode A, e.g. B. "S" (sport), "N" (normal) or "K" (comfort) to be taken manually. Depending on this preselection and on the operating parameters m, v, B, the control device6 automatically adjusts the adjusting devices3 to5 of the struts1 and2 by means of stored characteristic maps. For example, the system recognizes the load m on the basis of the deflection state on the rear wheel guide and regulates it to a defined zero position at the start of the journey (integrated vehicle height control function). The damping force (Dh, Dv) and / or the spring force (Fh) is then adjusted to this loading condition; the corresponding settings of the adjustment devices3 to5 are stored in a map. In addition, the damping forces (Dv, Dh) and / or the spring force (Fh) are dynamically adapted to the current driving condition depending on the speed v, the acceleration (dv / dt) or the braking process B. By recognizing the speed v, the system preferably prevents the vehicle from being driven in the high-speed range that is critical to driving dynamics without sufficient damping force (Dv, Dh). Conversely, at very low speeds v, the damping force (Dv, Dh) is automatically adjusted for comfort.
Der Fahrer hat die zweite Auswahlmöglichkeit, über das Display8 im Modus M die Parameter "Dämpfungskraft vorne" (Dh), "Dämpfungskraft hinten" (Dh) und "Federkraft hinten" (Fh), z. B. in Form der Eingabe einer Kennzahl zwischen 1 und 12, frei und fest vorgegeben zu wählen. Die Auswahl ist z. B. bei allen Fahr- und Beladungszuständen möglich. Die Zug- und Druckstufendämpfung wird durch einen Parameter bzw. durch eine Kennzahl definiert. Die unabhängige Verstellung der Zug- und Druckstufendämpfung durch den Fahrer ist zwar möglich, wird jedoch aus Sicherheitsgründen vorzugsweise nicht zugelassen.The driver has the second selection option, via the display8 in the M mode, the parameters "damping force front" (Dh), "damping force rear" (Dh) and "spring force rear" (Fh), z. B. in the form of entering a key figure between 1's and 12's, to choose freely and permanently. The selection is e.g. B. possible in all driving and loading conditions. The rebound and compression damping is defined by a parameter or a key figure. Independent adjustment of the rebound and compression damping by the driver is possible, but is not permitted for safety reasons.
