Abstract
Description
Die Erfindung betrifft eine Aggregatlagerung gemäß dem Oberbegriff des Anspruch 1.The The invention relates to a storage unit according to the preamble of the claim 1.
Die Anforderungen an ein niedriges und für die Insassen komfortables Innengeräusch in Kraftfahrzeugen haben sich in den letzten Jahren dramatisch verschärft. Die verursachenden Geräuschquellen setzten sich aus Luftschall, beispielsweise Geräusche der Reifen auf der Fahrbahn, der Fahrtwind und Geräusche vom Gebläse, und aus Körperschall zusammen, beispielsweise Geräusche vom Antrieb und der Hilfsaggregate.The Requirements for a low and comfortable for the occupants interior noise in automobiles have dramatically worsened in recent years. The causing noise sources Sounds of airborne noise, such as the noise of tires on the road, the wind and noise from the blower, and from structure-borne sound together, for example, noises from the drive and auxiliary equipment.
Die Geräusche, die durch zahlreiche Bauteile und Anregungen von außen, der Luft, der Straße usw. beeinflusst werden, können im Wesentlichen durch Dämpfung und/oder durch Abkopplung für den Insassen vermindert werden. Hierzu werden unter anderem auch Motorlager verwendet, die eine Übertragung des Körperschalls des Antriebsaggregats vermindern.The Sounds, due to numerous components and suggestions from the outside, the Air, the road, etc. can be influenced essentially by damping and / or by decoupling for be reduced to the inmates. This will include, among others Engine mounts used that a transmission of structure-borne sound reduce the drive unit.
In konventionellen Aggregatlagerungen von Kraftfahrzeugen, insbesondere von Kraftfahrzeugen der Oberklasse, werden die Motorlager als Hydrolager ausgeführt. Dies sind Motorlager, die im Inneren eine Flüssigkeit aufweisen. Bei einigen Kraftfahrzeugen werden zusätzlich auch hydraulisch gedämpfte Getriebelager eingesetzt.In conventional aggregate bearings of motor vehicles, in particular Of motor vehicles of the upper class, the engine mounts as hydraulic bearings executed. These are engine mounts that have a liquid inside. For some Motor vehicles will be additional also hydraulically damped transmission bearings used.
Die Wirkrichtung der Schwingungsdämpfung liegt allerdings bei diesen Anwendungen in der Hauptwirkachse des Hydrolagers. Die Hauptwirkachse liegt im Wesentlichen in der Fahrzeughochrichtung. Bei der Übertragung der drei Raumdimensionen x-, y- und z-Richtung auf ein Kraftfahrzeug, wird im Folgenden die Längsrichtung des Kraftfahrzeugs mit x-Richtung, die Seitenrichtung mit y-Richtung und die Hochrichtung mit z-Richtung bezeichnet. Somit liegt die Hauptwirkachse des Hydrolagers im Wesentlichen in der z-Richtung des Kraftfahrzeugs.The Direction of action of the vibration damping is however, in these applications in the main axis of the hydraulic bearing. The main axis of rotation is essentially in the vehicle vertical direction. In the transmission the three spatial dimensions x-, y- and z-direction on a motor vehicle, in the following, the longitudinal direction of the motor vehicle with x-direction, the side direction with y-direction and the direction of z-direction. Thus lies the Main axis of the hydraulic bearing substantially in the z-direction of the motor vehicle.
Durch diese Anordnung wird üblicherweise eine akzeptable Bedämpfung der Aggregatschwingungen in der z-Richtung erreicht, die aufgrund von Unebenheiten des Fahrzeuguntergrundes auftreten. Da die Eigenschwingungsform in Fahrzeuglängsrichtung bzw. x-Richtung jedoch im Allgemeinen nicht einer Schwingungsdämpfung unterliegt, führt dies zu Komforteinbußen. Insbesondere führt dies zu Komforteinbußen bei einer Schwingungsanregung in Längsrichtung, beispielsweise durch Längsstöße und/oder Schlagleisten.By This arrangement is usually a acceptable damping the aggregate oscillations in the z-direction reached, due to of bumps of the vehicle surface occur. Since the natural mode in the vehicle longitudinal direction or x-direction however, generally not subject to vibration damping will result to loss of comfort. In particular, leads this to comfort loss at a vibration excitation in the longitudinal direction, for example by longitudinal joints and / or Blow bars.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Aggregatlagerung für eine Brennkraftmaschine in einem Kraftfahrzeug der eingangs genannten Art derart auszuführen, dass dabei neben der Schwingungsdämpfung in z-Richtung eine zusätzliche Schwingungsdämpfung in x-Richtung erfolgt.In front In this background, the invention is based on the object Aggregate storage for one Internal combustion engine in a motor vehicle of the aforementioned Kind of doing this that in addition to the vibration damping in the z-direction an additional vibration damping takes place in the x direction.
Diese Aufgabe wird gelöst mit einer Aggregatlagerung gemäß den Merkmalen des Patentanspruchs 1. Die Unteransprüche betreffen besonders zweckmäßige Weiterbildungen der Erfindung.These Task is solved with an aggregate storage according to the features of the claim 1. The dependent claims relate to particularly expedient developments the invention.
Erfindungsgemäß ist also eine Aggregatlagerung vorgesehen, bei der eine Schwingungsdämpfung im Wesentlichen in z-Richtung vorgesehen ist, die durch mindestens einem Hydrolager erfolgt, das zwischen der Brennkraftmaschine und der Fahrzeugkarosserie angeordnet ist. Wesentliche Idee ist, dass bei der Aggregatlagerung ferner eine weitere Schwingungsdämpfung im Wesentlichen in x-Richtung vorgesehen ist. Aufgrund der Kombination der Dämpfung sowohl der Schwingungen in z-Richtung als auch der Schwingungen in x-Richtung wird eine weitgehende Bedämpfung der für den Fahrkomfort relevanten Aggregat-Eigenformen erreicht. Mit Eigenformen sind Schwingungen des Aggregats im Resonanzfall bezeichnet. Dies sind mathematisch auch die Lösungen der Eigenwertgleichungen für dieses Schwingungssystem.According to the invention is thus an aggregate storage provided in which a vibration damping in Essentially provided in z-direction, by at least a hydraulic bearing takes place between the engine and the vehicle body is arranged. Essential idea is that at the aggregate storage further a further vibration damping in Essentially provided in the x direction. Because of the combination the damping both the vibrations in the z-direction and the vibrations in the x direction a substantial damping the for the ride comfort relevant aggregate eigenmodes reached. With eigen forms are vibrations of the aggregate in the case of resonance. This are mathematically also the solutions the eigenvalue equations for this Vibration system.
Bei einer vorteilhaften Ausführungsform der vorliegenden Erfindung ist für die Schwingungsdämpfung in x-Richtung mindestens ein Dämpferelement vorgesehen, das in der x-Richtung zwischen der Brennkraftmaschine und der Fahrzeugkarosserie angeordnet ist. Die Verwendung eines reinen Dämpferelements ist kostengünstig und einfach realisierbar.at an advantageous embodiment the present invention is for the vibration damping at least one damper element in the x direction provided in the x-direction between the internal combustion engine and the vehicle body is arranged. The use of a pure damper element is inexpensive and easy to implement.
Bei einer bevorzugten Ausführungsform der vorliegenden Erfindung ist für die Schwingungsdämpfung in x-Richtung mindestens ein zusätzliches Hydrolager vorgesehen, das in der x-Richtung zwischen der Brennkraftmaschine und der Fahrzeugkarosserie angeordnet ist. Besonders vorteilhaft ist das zusätzliche Hydrolager am Getriebeende zwischen der Brennkraftmaschine und der Fahrzeugkarosserie angeordnet.at a preferred embodiment the present invention is for the vibration damping at least one additional hydraulic bearing in the x direction provided in the x direction disposed between the internal combustion engine and the vehicle body is. Particularly advantageous is the additional hydraulic bearing at the transmission end disposed between the internal combustion engine and the vehicle body.
Bei einer alternativen Ausführungsform der vorliegenden Erfindung weisen die Hydrolager, eine Schwingungsbuchse auf, um eine Schwingungsdämpfung in der x-Richtung zu bewirken. Durch die Bereitstellung der Hydrobuchse an dem Hydrolager wird die dämpfende Funktion des Lagers in z-Richtung nicht beeinträchtigt. Die zusätzliche schwingungsdämpfende Wirkung in x-Richtung wird hierbei ohne Einbau zusätzlicher Bauteile erreicht. Dies führt sowohl zu einer Reduzierung der Herstellungskosten sowie zu einer Verringerung des benötigten Raumes, um die angestrebten Verbesserung des Fahrkomforts zu erzielen.at an alternative embodiment of the present invention, the hydraulic bearings, a vibration bushing on to a vibration damping in the x direction. By providing the hydro bushing At the hydraulic bearing becomes the damping Function of the bearing in z-direction not impaired. The additional antivibration Effect in the x-direction is without additional installation Achieved components. This leads both to a reduction of manufacturing costs and to a reduction of the needed Space to achieve the desired improvement in ride comfort.
