Description
Die Erfindung betrifft eine Vorrichtung zur Reduzierung von NVH bei einer Kraftfahrzeug-Radaufhängung mittels eines Schwingungstilgers gemäß dem Oberbegriff des Anspruchs 1. The invention relates to a device for reducing NVH in a motor vehicle suspension by means of a vibration damper according to the preamble of claim 1.
Ein Schwingungstilger ist eine Art von Schwingungsdämpfer, der anders als gewöhnliche Schwingungsdämpfer nicht zwischen zwei Objekten befestigt ist, sondern nur an einem, und der mittels einer schwingfähigen Masse nur bestimmte Schwingfrequenzen bedämpft, während gewöhnliche Schwingungsdämpfer mehr oder weniger frequenzunabhängig arbeiten. A vibration damper is a type of vibration damper, which unlike ordinary vibration damper is not attached between two objects, but only one, and attenuated by means of a vibrating mass only certain frequencies, while ordinary vibration dampers operate more or less frequency independent.
Es ist übliche Praxis, Schwingungstilger zur Verbesserung der Fahreigenschaften eines Fahrzeugs einzusetzen. Ein Schwingungstilger wird am Fahrzeugrahmen befestigt und so abgestimmt, dass er bei einer vorher festgelegten Frequenz mitschwingt und dadurch resonanten Fahrzeugvibrationen entgegenwirkt. It is common practice to use vibration absorbers to improve the driving characteristics of a vehicle. A vibration damper is attached to the vehicle frame and tuned so that it resonates at a predetermined frequency and thereby counteract resonant vehicle vibrations.
Insbesondere bei Personenwagen verwendet man Schwingungstilger auch zur Verbesserung des Fahrkomforts, welcher durch störende Geräusche und Vibrationen im Kraftfahrzeug beeinträchtigt werden kann. Diese Einflüsse werden zusammengefasst als NVH (Noise, Vibration, Harshness) bezeichnet. In particular, in passenger cars used vibration absorber also to improve the ride comfort, which can be affected by disturbing noise and vibration in the vehicle. These influences are collectively referred to as NVH (Noise, Vibration, Harshness).
Zur Verminderung von resonanten Schwingungen, die durch die Fahrbahn und/oder die Rad/Reifen-Baugruppe angeregt werden, kann man einen Schwingungstilger direkt mit einem Achsschenkel koppeln, wie aus der gattungsbildenden
Der Erfindung liegt die Aufgabe zu Grunde, eine NVH-Reduzierung bei einer Kraftfahrzeug-Radaufhängung mittels eines Schwingungstilgers zu ermöglichen, der besonders leicht hergestellt, angebracht und untergebracht werden kann. The invention is based on the object to enable an NVH reduction in a motor vehicle suspension by means of a vibration damper, which can be particularly easily manufactured, mounted and accommodated.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. This object is achieved by a device having the features of claim 1.
Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Advantageous developments of the invention are specified in the dependent claims.
Ein Stabilisator für Kraftfahrzeuge, der auch Querstabilisator oder Wankstabilisator genannt wird, enthält eine meist U-förmige Torsionsstange, deren langgestreckte Basis parallel zu einer Radachse am Fahrzeugrahmen angelenkt ist und deren Schenkel-Enden über Koppelstangen mit einem rechten bzw. einem linken Radführungselement der rechten bzw. linken Radaufhängung verbunden sind. Der Stabilisator verbindet somit gegenüberliegende Räder derart, dass beim Einfedern eines Rades das gegenüberliegende Rad ebenfalls etwas einfedert, um bei Kurvenfahrten einem Wanken der Karosserie entgegenzuwirken. A stabilizer for motor vehicles, which is also called anti-roll bar or anti-roll bar, contains a mostly U-shaped torsion bar whose elongated base is articulated parallel to a wheel axle on the vehicle frame and the leg ends via coupling rods with a right or a left wheel guide the right or left suspension are connected. The stabilizer thus connects opposing wheels such that upon compression of a wheel, the opposite wheel also slightly springs to counteract when cornering a rolling of the body.
Gemäß der Erfindung werden Stabilisator-Koppelstangen mit Schwingungstilgern versehen. Hierfür sind überhaupt keine Modifizierungen an der Radaufhängung erforderlich, nicht einmal an der Koppelstange selbst, weil man Schwingungstilger z. B. einfach durch Klemmwirkung oder Schweißen daran befestigen kann. Aber selbst wenn man die Koppelstange speziell für Befestigung des Schwingungstilgers auslegen würde, wäre dies wesentlich einfacher und gewichtssparender zu bewerkstelligen als einen Achsschenkel oder ein Federbein dafür auszulegen. According to the invention stabilizer coupling rods are provided with vibration absorbers. For this, no modifications to the suspension are required, not even on the coupling rod itself, because you vibration damper z. B. simply by clamping action or welding can attach it. But even if you would interpret the coupling rod specifically for attachment of the vibration, this would be much easier and weight-saving to accomplish than interpret a stub axle or a strut for it.
Weiterhin steht im Bereich einer Stabilisator-Koppelstange normalerweise viel Platz zur Verfügung, wo ein Schwingungstilger in keiner Weise stört, während man bei den bekannten Vorrichtungen Kompromisse eingehen muss, nämlich zwischen den Funktionalitäten des Schwingungstilgers und jenen des Bauteils, das den Schwingungstilger trägt. Furthermore, in the area of a stabilizer coupling rod, there is usually a lot of space available where a vibration damper in no way disturbs, while compromises have to be made in the known devices, namely between the functionalities of the vibration absorber and those of the component carrying the vibration absorber.
Die mit einem Schwingungstilger versehene Stabilisator-Koppelstange bildet eine integrale Baugruppe, welche leicht in vielen verschiedenen Ausführungen hergestellt werden kann, die sich z. B. in ihren Resonanzfrequenzen, Gewichten und/oder Arbeitsprinzipien unterscheiden, und welche auch leicht montiert oder ausgewechselt werden kann, so dass man viele unterschiedliche Kraftfahrzeuge leicht mit einer passenden NVH-Reduzierung ausrüsten kann, ohne irgendwelche komplexen Bauteile dafür modifizieren zu müssen. The provided with a vibration damper stabilizer coupling rod forms an integral assembly, which can be easily manufactured in many different designs, the z. B. differ in their resonance frequencies, weights and / or operating principles, and which can also be easily assembled or replaced, so you can easily equip many different vehicles with a suitable NVH reduction, without having to modify any complex components for it.

In einer bevorzugten Ausführungsform der Erfindung ist der Schwingungstilger dafür ausgelegt, Schwingungen der Koppelstange bzw. eines damit verbundenen Radführungselements in einem oder mehreren vorbestimmten Frequenzbereichen, aber nicht bei anderen Frequenzen entgegenzuwirken. Für NVH typische Frequenzen sind z. B. einige zehn oder hundert Hz. In a preferred embodiment of the invention, the vibration damper is designed to counteract oscillations of the coupling rod or an associated wheel guide element in one or more predetermined frequency ranges, but not at other frequencies. NVH typical frequencies are z. For example, tens or hundreds of Hz.
Die Erfindung eignet sich besonders für MacPhearson-Radaufhängungen und insbesondere MacPhearson-Vorderradaufhängungen, wobei für eine rechte und eine linke Radaufhängung je eine Koppelstange mit Schwingungstilger vorgesehen wird. The invention is particularly suitable for MacPhearson wheel suspensions and in particular MacPhearson front suspensions, wherein for each of a right and a left wheel suspension a coupling rod is provided with vibration damper.
Der Schwingungstilger kann ein passiver Schwingungstilger sein, vorzugsweise entweder mit einer schwingfähigen Masse in Form einer langgestreckten elastischen Lippe oder Rippe, deren eine Längskante an der Koppelstange befestigt ist, oder in Form von einem oder mehreren länglichen Klötzen, die mittels elastischer Elemente an der Koppelstange befestigt sind. The vibration absorber may be a passive vibration absorber, preferably either with an oscillatory mass in the form of an elongate elastic lip or rib, one longitudinal edge of which is attached to the coupling rod, or in the form of one or more elongated blocks which are secured to the coupling rod by means of elastic elements are.
Alternativ kann der Schwingungstilger ein aktiver, bedarfsweise ein- und ausschaltbarer Schwingungstilger sein, dessen schwingfähige Masse durch einen elektrisch betätigbaren, vorzugsweise elektromagnetischen oder piezoelektrischen Aktuator mit der Koppelstange verbunden ist. Alternatively, the vibration damper can be an active, if necessary switched on and off vibration absorber whose oscillatory mass is connected by an electrically actuated, preferably electromagnetic or piezoelectric actuator with the coupling rod.
Alternativ können auch irgendwelche anderen Methoden zur Schwingungstilgung verwendet werden. Alternatively, any other method of vibration damping can be used.
