Gemäß
Das Überlagerungsgetriebe
Durch die vorstehende Vorrichtung wird ein Verfahren zur Dämpfung eines Radhubs bei der Fahrzeugrad-Antriebseinrichtung
Bei dem Verfahren wird der elektrische Rad-Antriebsmotor
Je nach Art des Übertragungsgetriebes kann die Radhubbewegung nahezu beliebig übersetzt bzw. untersetzt werden, wobei das Verhältnis zwischen MD-max und dem Antriebsmoment variiert wird. Ziel der gewählten Übersetzung oder Untersetzung ist es, MD-MAX zu reduzieren, wobei nicht nur die Übersetzung bzw. Untersetzung sondern auch das Verhältnis gefederte und gefederte Masse und der Reifenradius sowie die Dynamik des Antriebsmotors zu berücksichtigen ist, um die Dynamik der Dämpfungsregelung zu optimieren. MD-MAX sollte jedoch nur so weit reduziert werden, wie es die gewünschte Regeldynamik und das Ansprechverhalten des Dämpfers zulassen.Depending on the type of transmission, the Radhubbewegung can be translated or squared almost arbitrary, the ratio between M D-max and the drive torque is varied. The aim of the selected ratio or reduction is to reduce M D-MAX , taking into account not only the ratio and reduction but also the ratio of sprung and sprung mass and the tire radius and the dynamics of the drive motor to the dynamics of the damping control optimize. However, M D-MAX should only be reduced as much as the desired control dynamics and damper response allow.
Bei der Erfindung wird die Drehrichtung des Übertragungsgetriebes vorteilhafter Weise so gewählt, dass die natürliche Nickbewegung des Fahrzeugs, d. h. das Einfedern der Vorderseite des Fahrzeugs beim Bremsen und das Ausfedern beim Beschleunigen, genutzt wird. Die durch das Übertragungsgetriebe entstandene Kopplung zwischen Fahrzeugbeschleunigung und Radbeschleunigung wird dadurch so ausgelegt, dass beim Beschleunigen des Fahrzeugs das Rad an der Vorderachse nach oben beschleunigt und das Rad an der Hinterachse nach unten beschleunigt. Der kinematische Nickausgleich der Radaufhängung wird durch den Nickausgleich aus der erfindungsgemäßen Vorrichtung entsprechend unterstützt.In the invention, the direction of rotation of the transmission gear is advantageously chosen so that the natural pitching motion of the vehicle, d. H. the compression of the front of the vehicle during braking and the rebound during acceleration, is used. The resulting between the transmission transmission coupling between vehicle acceleration and wheel acceleration is thereby designed so that when accelerating the vehicle accelerates the wheel on the front axle up and accelerates the wheel on the rear axle down. The kinematic pitch compensation of the suspension is supported by the pitch compensation from the device according to the invention accordingly.
Die Erfindung ist nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. Insbesondere ist die Erfindung nicht auf die Verwendung eines Planetengetriebes an dem Rad-Antriebsmotor beschränkt, da die Erfindung auch bei anderen Getriebearten, insbesondere Koppelgetrieben, möglich ist.The invention is not limited to the embodiment described above. In particular, the invention is not limited to the use of a planetary gear on the wheel drive motor, since the invention is also possible in other types of transmission, in particular coupling gears.
Außerdem ist die Erfindung nicht auf die Anbindung an die Vorderachse des Fahrzeugs beschränkt, insbesondere kann die Erfindung auch bei Radaufhängung an der Hinterachse und bei einer Längslenker-Hinterachse angewendet werden. Bei der Anbindung an die Längslenker-Hinterachse kann der Rad-Antriebsmotor radseitig drehbar an der Längsschwinge der Radaufhängung angebracht werden, und sein Gehäuse wird beim Federn in eine Relativdrehung versetzt, was durch einen zusätzlichen oben am Rad-Antriebsmotor angeordneten Motorlenker verwirklicht werden kann. Als Überlagerungsgetriebe kann in diesem Fall ein Vier-Gelenk vorgesehen werden, welches die Radhubbewegung der Wellendrehung des Rad-Antriebsmotors überlagert. Außerdem ist auch eine Anbindung bei einer Anordnung möglich, bei der der Rad-Antriebsmotor am Längslenker bzw. dem Motorlenker angeboten ist. Bei diesen abgewandelten Ausführungsformen kommt es darauf an, dass die Radhubbewegung dem Motor-Drehmoment überlagert wird, um bei laufendem Rad-Antriebsmotor eine Radhubdämpfung zu erzielen.In addition, the invention is not limited to the connection to the front axle of the vehicle, in particular, the invention can also be applied to suspension on the rear axle and a trailing arm rear axle. When connecting to the trailing arm rear axle of the wheel drive motor can be rotatably mounted wheel side on the longitudinal rocker of the suspension, and its housing is offset during the springs in a relative rotation, which can be realized by an additional top of the wheel drive motor arranged engine handlebar. As a superposition gear, a four-joint can be provided in this case, which superimposes the Radhubbewegung the shaft rotation of the wheel drive motor. In addition, a connection in an arrangement is possible in which the wheel drive motor on Trailing arm or the engine handlebar is offered. In these modified embodiments, it is important that the Radhubbewegung is superimposed on the engine torque to achieve a Radhubdämpfung while the wheel drive motor is running.
