Description
Die Erfindung betrifft eine Aggregate-Befestigung zum Festlegen mindestens eines Aggregats eines Antriebs an einer Karosserie und/oder an einem Fahrwerk eines Kraftfahrzeugs, nach dem Oberbegriff des ersten Anspruchs.The invention relates to an aggregate attachment for fixing at least one unit of a drive on a body and / or on a chassis of a motor vehicle, according to the preamble of the first claim.
Aggregatelager d. h. Lagerungen für das Antriebsaggregat (Motor und/oder Getriebe) für Kraftfahrzeuge sind in unterschiedlichsten Ausführungsformen bekannt. Sie können Schwingungen bzw. Relativbewegungen zwischen dem Antriebsaggregat und der Fahrzeug-Karosserie ermöglichen, jedoch sollen diese Relativbewegungen nicht nur gedämpft, sondern auch in der Distanz oder Auslenkung begrenzt werden, um zu vermeiden, dass Teile des Antriebsaggregates in unerwünschter Weise an der Fahrzeug-Karosserie anschlagen.Assembly storage d. H. Bearings for the drive unit (engine and / or transmission) for motor vehicles are known in various embodiments. They may allow vibrations or relative movements between the drive unit and the vehicle body, but these relative movements should not only be damped, but also limited in the distance or deflection, to avoid that parts of the drive unit in an undesirable manner to the vehicle body attacks.
Aus der
Bei Aggregatlagerungen, zum Beispiel mit zwei Motorlagern und einem Getriebelager, besteht grundsätzlich ein Zielkonflikt bei der Lagerabstimmung hinsichtlich Stuckern, also Schwingungen in Richtung der Hochachse, Solidität, also Querschwingungen im Mischverbund mit Schwingungen in allen Richtungen und Körperschalleintrag in die Karosserie, also Innenraumakustik. Es sind möglichst steife Lager notwendig, um Stuckern und Solidität zu mindern und möglichst weiche Lager zu verwenden, um den Körperschalleintrag in die Karosserie zu minimieren. Zur weiteren Minimierung der Solidität wäre weiterhin eine schwerpunktsnahe Lagerung des Aggregats notwendig.In aggregate bearings, for example, with two engine mounts and a gearbox bearing, there is always a conflict of objectives in the camp vote regarding stucco, ie vibrations in the direction of the vertical axis, solidity, ie transverse vibrations in the composite compound with vibrations in all directions and body noise in the body, so interior acoustics. As stiff as possible bearings are necessary to reduce stuttering and solidity and to use the softest possible bearings to minimize the body sound entry into the body. To further minimize the solidity, it would also be necessary to mount the unit close to the center of gravity.
Aufgabe der vorliegenden Erfindung ist es, eine Aggregate-Befestigung zum Festlegen von Aggregaten eines Antriebs an einer Karosserie und/oder an einem Fahrwerk eines Kraftfahrzeugs bereitzustellen, die eine optimierte Schwingungsisolierung zwischen Antriebsaggregat und Aufbau des Fahrzeugs gewährleistet, bei gleichzeitiger Komfortverbesserung hinsichtlich Stuckern und Solidität.Object of the present invention is to provide an aggregate attachment for specifying aggregates of a drive on a body and / or on a chassis of a motor vehicle, which ensures optimized vibration isolation between the drive unit and the structure of the vehicle, while improving comfort in terms of stucco and solidity.
Die Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The object is achieved with the characterizing features of
Nach der Erfindung ist eine Aggregate-Befestigung zum schwingfähigen Festlegen von Aggregaten eines Antriebs, insbesondere Motor und/oder Getriebe, an einer Karosserie und/oder an einem Fahrwerk eines Kraftfahrzeugs, mittels Schwingungen dämpfenden Elementen, wovon wenigstens drei als Traglager am Aggregat, in Richtung der Hochachse gesehen, im Bereich unterhalb dessen Schwerpunkt angebracht sind, dadurch gekennzeichnet, dass wenigstens ein weiteres Schwingungen dämpfendes Element in Fahrzeuglängs- und -querrichtung in der Nähe des Aggregatschwerpunkts und in Richtung der Fahrzeughochachse über dem Aggregatschwerpunkt, insbesondere im oberen Drittel des Aggregats, angeordnet ist.According to the invention, an aggregate attachment for vibratory fixing of aggregates of a drive, in particular engine and / or transmission, to a body and / or on a chassis of a motor vehicle, by means of vibration damping elements, of which at least three as a support bearing on the unit, in the direction Seen in the vertical axis, are mounted in the region below the center of gravity, characterized in that at least one further vibration damping element in the vehicle longitudinal and transverse direction in the vicinity of the center of gravity and in the direction of the vehicle vertical axis above the center of gravity, in particular in the upper third of the unit arranged is.
Das hat den Vorteil einer Komfortverbesserung hinsichtlich Stuckern und Solidität bei gleichem Isolationsverhalten wie bei der herkömmlichen Lageranordnung. Außerdem bringt die Lageranordnung eine verbesserte Drehmomentabstützung des Aggregates.This has the advantage of improving comfort in terms of stucco and solidity with the same insulation behavior as in the conventional bearing arrangement. In addition, the bearing assembly brings an improved torque support of the unit.
Vorteilhafte Ausführungsformen der Erfindung sehen vor, dass das weitere Schwingungen dämpfende Element ein Traglager oder eine Drehmomentstütze ist. Wenn dann das Aggregat über die Traglager an der Karosserie und/oder am Fahrwerk in horizontaler Richtung im wesentlichen frei ausschwingend gehalten ist und das weitere Schwingungen dämpfende Element dieses Ausschwingen dämpfende Kennungen aufweist, hat das den Vorteil, dass eine Aufhängung für ein längseingebautes Antriebsaggregat eines Fahrzeugs geschaffen ist, durch die eine Funktionstrennung von Gewichtsaufnahme und Drehmomentabstützung und hieraus resultierend eine getrennte Abstimmbarkeit einzelner Eigenschwingungsfrequenzen mit weiteren Vorteilen möglich wird. Nämlich ein guter Fahrkomfort durch vorteilhafte getrennte Abstimmöglichkeit für Motorstuckern und Lastwechselreaktionen, eine Abkopplung von Leerlaufschwingungen durch eine weiche Federkennung der Drehmomentabstützung bei relativ kleinen Schwingwegen, ein geringes Innengeräusch durch geringe dynamische Steifigkeiten der Motor- und Getriebetraglager.Advantageous embodiments of the invention provide that the further vibration-damping element is a support bearing or a torque arm. If then the aggregate on the support bearing on the body and / or on the chassis in the horizontal direction is kept substantially free swinging and the further vibration damping element of this decay damping characteristics, this has the advantage that a suspension for a longitudinally built drive unit of a vehicle is created, through which a separation of functions of weight and torque support and, as a result, a separate tunability of individual natural frequencies with other advantages is possible. Namely, a good ride comfort by advantageous separate tuning for engine stucco and load change reactions, a decoupling of idling vibrations by a soft spring detection of the torque support at relatively small vibration paths, low internal noise due to low dynamic stiffness of the engine and Getriebetraglager.
Weitere vorteilhafte Ausführungsformen der Erfindung sehen vor, dass das weitere Schwingungen dämpfende Element ein vertikal ausgerichtetes Druckpolster und einen in Fahrzeugquerrichtung wirkenden Anschlag besitzt. Bei der Ausbildung des weitere Schwingungen dämpfenden Elements als statisch belastetes Traglager ist eine Anpassung der Steifigkeiten der drei Traglager erforderlich, um ein gleiches Isolationsverhalten bzgl. Körperschalleintrag in die Karosserie des Lagerverbundes entsprechend einer Lagerung nach dem Stand der Technik zu bekommen. Bei einer Ausbildung des weitere Schwingungen dämpfenden Elements als statisch unbelastetes Stützlager mit einfacher oder doppelter Entkopplung müssen die Lagersteifigkeiten der Traglager nicht zwingend angepasst werden. Das Isolationsverhalten das Lagerverbundes bleibt wie bei einer Lagerung ohne weiteres Schwingungen dämpfendes Element annähernd gleich. Die Orientierung der Lagerachse (in x, y oder Z-Achse des Fahrzeugs) des weitere Schwingungen dämpfenden Elements ist je nach Lagerart (Trag- oder Stützlager) und deren richtungsabhängigen Lagersteifigkeiten zu wählen.Further advantageous embodiments of the invention provide that the further vibration-damping element has a vertically aligned pressure pad and a stop acting in the vehicle transverse direction stop. In the formation of the further vibration damping element as a statically loaded support bearing an adjustment of the stiffnesses of the three support bearings is required to get the same isolation behavior with respect. Body sound entry into the body of the bearing assembly according to a storage according to the prior art. In an embodiment of the further vibration damping element as static unloaded support bearing with single or double decoupling, the bearing stiffness of the support bearing need not necessarily be adjusted. The insulation behavior of the bearing assembly remains approximately the same as in a storage without further vibration damping element. The orientation of the bearing axis (in the x, y or Z axis of the vehicle) of the further vibration damping element is to choose depending on the type of bearing (support or support bearings) and their directional bearing stiffness.
Vorteilhafterweise bestehen so sehr viele verschiedene Möglichkeiten zur Entkopplung der Aggregatschwingungen auf einfache Weise und somit zur Verbesserung der Akustik im Fahrzeuginnenraum.Advantageously, there are so many different possibilities for decoupling the unit vibrations in a simple manner and thus to improve the acoustics in the vehicle interior.
