Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Radaufhängung mit wenigstens einem Fahrwerksbauteil, einem Radnabenantrieb und wenigstens einem mit einer Fahrzeugkarosserie koppelbaren Fahrwerkslager.The invention relates to a suspension with at least one chassis component, a wheel hub drive and at least one can be coupled to a vehicle body chassis bearings.
Hintergrund der ErfindungBackground of the invention
Derzeit werden Fahrwerke für PKWs entwickelt, die Radnabenantriebe aufweißen.Currently, chassis for cars are developed, the wheel hub drives aufwei.
Radnabenantriebe können sowohl während einer Beschleunigungsphase als auch bei einem Bremsvorgang besser, insbesondere schneller und mit steileren Zugkraftgradienten, geregelt werden als ein herkömmlicher Antrieb bzw. eine herkömmliche Bremsanlage. Um diese gute Regelbarkeit umzusetzen, werden Radaufhängungen bzw. Fahrwerke benötigt, die eine große Steifigkeit in Fahrzeuglängsrichtung aufweisen. Andererseits sind auch elastokinematische und akustische Anforderungen zu berücksichtigen, so dass das Vorsehen herkömmlicher Lager nicht zweckmäßig ist. Herkömmliche Radaufhängungen sowie halbstarre Achsen und Starrachsen besitzen jeweils Lager, die hinsichtlich der Federungs- und Dämpfungseigenschaften speziell angepasst sind. Diese Abstimmung ist jedoch nicht für alle denkbaren Betriebssituationen optimal.Hub drives can be better controlled both during an acceleration phase and during a braking operation, in particular faster and with steeper Zugkraftgradienten, as a conventional drive or a conventional brake system. To implement this good controllability, wheel suspensions or chassis are required, which have a high rigidity in the vehicle longitudinal direction. On the other hand, elastokinematische and acoustic requirements are taken into account, so that the provision of conventional bearings is not appropriate. Conventional wheel suspensions and semi-rigid axles and rigid axles each have bearings that are specially adapted in terms of suspension and damping properties. However, this tuning is not optimal for all conceivable operating situations.
Zusammenfassung der ErfindungSummary of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Radaufhängung anzugeben, die in der Lage ist, steile Zugkraftgradienten zu übertragen.The invention has for its object to provide a suspension that is able to transfer steep Zugkraftgradienten.
Zur Lösung dieser Aufgabe ist bei einer Radaufhängung der eingangs genannten Art erfindungsgemäß vorgesehen, dass das wenigstens eine Fahrwerkslager als adaptives Lager mit einstellbarer Elastizität oder als passiv progressiv wirkendes Lager ausgebildet ist.To solve this problem is provided according to the invention in a suspension of the type mentioned that the at least one chassis bearing is designed as an adaptive bearing with adjustable elasticity or as a passive progressively acting bearing.
Die Erfindung beruht auf der Idee, bei einer Radaufhängung wenigstens ein Fahrwerkslager mittels eines adaptiven Lagers mit einstellbarer Elastizität bzw. Steifigkeit zu verspannen. Durch das Verspannen kann ein steiler Zugkraftgradient, der durch einen Radnabenantrieb beim Beschleunigen oder Bremsen erzeugt wird, übertragen werden.The invention is based on the idea of bracing at least one chassis bearing in a suspension by means of an adaptive bearing with adjustable elasticity or rigidity. By bracing, a steep draft gradient generated by a wheel hub drive during acceleration or braking can be transmitted.
Im Vergleich zur Verwendung steiferer Lager weist die erfindungsgemäße Lösung den Vorteil auf, dass die Elastizität des adaptiven Lagers lediglich bei Bedarf geändert wird, das heißt wenn ein großer Zugkraftgradient vorliegt, insbesondere bei einem Beschleunigungs- oder einem Bremsvorgang. In den übrigen Betriebszuständen weist das adaptive Lager hingegen eine niedrigere Steifigkeit auf.In comparison with the use of stiffer bearings, the solution according to the invention has the advantage that the elasticity of the adaptive bearing is changed only when necessary, that is to say when there is a large tensile force gradient, in particular during an acceleration or braking process. In the other operating states, however, the adaptive bearing has a lower rigidity.
Alternativ kann das wenigstens eine Fahrwerkslager der erfindungsgemäßen Radaufhängung als passiv progressiv wirkendes Lager ausgebildet sein. Ein derartiges spezielles passiv progressiv wirkendes Lager ist so gestaltet, dass es eine frequenzabhängige Steifigkeitskennlinie aufweist. Bei steigender Frequenz steigt die Steifigkeit und damit die Widerstandskraft des Lagers gegenüber einwirkenden Belastungen zunächst flach an. Bei höheren Frequenzen steigt die Steifigkeit dann zunehmend (progressiv) an, wodurch sich schnell ändernde Kräfte steifer abgestützt werden, in diesem Fall also der „Verlustweg” in der Radaufhängung verringert wird. Verlustweg ist der Weg, den das unter Längskraft stehende Rad relativ zum Fahrzeug zurücklegt, bis die volle Wirkung der gewünschten Längskraft (Beschleunigung oder Bremsung) auf das Fahrzeug wirkt.Alternatively, the at least one chassis bearing of the suspension according to the invention may be formed as a passive progressively acting bearing. Such a special passive progressive bearing is designed to have a frequency dependent stiffness characteristic. As the frequency increases, the rigidity and thus the resistance of the bearing initially increases in a flat manner against acting loads. At higher frequencies, the stiffness then increases progressively (progressive), whereby rapidly changing forces are supported stiffer, in this case, the "loss" in the suspension is reduced. Loss path is the path traveled by the longitudinal force wheel relative to the vehicle until the full effect of the desired longitudinal force (acceleration or braking) acts on the vehicle.
Bei der erfindungsgemäßen Radaufhängung wird es bevorzugt, dass das adaptive Lager derart angeordnet ist, dass dessen Elastizität in horizontaler Richtung einstellbar ist. Auf diese Weise kann die gewünschte Steifigkeit des Lagers in Situationen mit großer Längsdynamik erzeugt werden.In the suspension of the invention, it is preferred that the adaptive bearing is arranged such that its elasticity is adjustable in the horizontal direction. In this way, the desired stiffness of the bearing can be generated in situations with great longitudinal dynamics.
Adaptive Lager sind an sich bekannt, als Beispiel wird auf die
Bei der erfindungsgemäßen Radaufhängung kann es auch vorgesehen sein, dass bei dem adaptiven Lager die Dämpfung einstellbar ist, insbesondere in horizontaler Richtung. Dementsprechend kann das adaptive Lager eingesetzt werden, um die Steifigkeit und/oder die Dämpfung einzustellen. Durch diese Einstellmöglichkeiten wird eine gute Anpassung an unterschiedliche Betriebszustände erreicht.In the suspension of the invention, it may also be provided that in the adaptive bearing, the damping is adjustable, in particular in the horizontal direction. Accordingly, the adaptive bearing can be used to adjust the stiffness and / or the damping. These adjustment options achieve a good adaptation to different operating states.
Im Rahmen der Erfindung wird es bevorzugt, dass das adaptive Lager mechanisch oder elektromechanisch oder pneumatisch oder hydraulisch oder elektrorheologisch oder magnetorheologisch ansteuerbar ist. Sofern technisch möglich und sinnvoll ist auch eine Kombination mehrerer Ansteuerungsarten möglich.In the context of the invention it is preferred that the adaptive bearing is mechanically or electromechanically or pneumatically or hydraulically or electro-rheologically or magnetorheologically controllable. If technically possible and reasonable, a combination of several types of control is possible.
Bei der erfindungsgemäßen Radaufhängung kann das Fahrwerksbauteil als Querlenker, Schwertlenker, Längslenker, Verbundlenker oder Trapezlenker ausgebildet sein. Dementsprechend kann praktisch jedes Fahrwerksbauteil, das ein oder mehrere Lager aufweist, ein adaptives Lager mit einstellbarer Elastizität aufweisen. Im aktivierten Zustand kann mittels des adaptiven Lagers die Elastizität dieses Lagers gezielt eingestellt oder verändert werden, um eine bestimmte Steifigkeit zu erzeugen. Beispielsweise kann ein Verbundlenker zwei adaptive Lager oder zwei passiv progressiv wirkende Lager aufweisen.In the suspension according to the invention, the chassis component as a wishbone, Sword handlebar, trailing arm, torsion beam or trapezoidal link may be formed. Accordingly, virtually any suspension component having one or more bearings may include an adaptive bearing with adjustable elasticity. In the activated state, the elasticity of this bearing can be selectively adjusted or changed by means of the adaptive bearing in order to generate a specific rigidity. For example, a composite link may have two adaptive bearings or two passive progressively acting bearings.
In weiterer Ausgestaltung der Erfindung kann es vorgesehen sein, dass die Radaufhängung eine Steuerungseinrichtung aufweist oder damit verbindbar oder verbunden ist, die zum Einstellen der Elastizität des adaptiven Lagers ausgebildet ist. Die Steuerungseinrichtung kann somit in bestimmten Betriebszuständen, insbesondere wenn eine große Längsdynamik vorhanden ist, eingreifen und die Elastizität des adaptiven Lagers entsprechend anpassen, insbesondere durch Erhöhen der Steifigkeit. Vorzugsweise wird die Steifigkeit des adaptiven Lagers durch die Steuerungseinrichtung bei einem Beschleunigungs- oder Bremsvorgang erhöht.In a further embodiment of the invention, it may be provided that the suspension has a control device or is connectable or connected thereto, which is designed to adjust the elasticity of the adaptive bearing. The control device can thus intervene in certain operating states, in particular when a large longitudinal dynamic is present, and adapt the elasticity of the adaptive bearing accordingly, in particular by increasing the rigidity. Preferably, the rigidity of the adaptive bearing is increased by the controller in an acceleration or braking operation.
Daneben betrifft die Erfindung ein Fahrwerk für ein Kraftfahrzeug. Das erfindungsgemäße Fahrwerk zeichnet sich dadurch aus, dass es Randaufhängungen der beschriebenen Art aufweist. Vorzugsweise umfasst das Fahrwerk auch eine Steuerungseinrichtung, die dazu ausgebildet ist, eine Längsverspannung zwischen Vorderachse und Hinterachse durch Einstellen der Elastizität der adaptiven Lager zu erzeugen.In addition, the invention relates to a chassis for a motor vehicle. The chassis according to the invention is characterized in that it has edge suspensions of the type described. Preferably, the chassis also comprises a control device, which is designed to generate a longitudinal tension between the front axle and the rear axle by adjusting the elasticity of the adaptive bearings.
