Abstract
Damit vom elektromechanischen Aktuator des Stabilisators verursachte Störgeräusche beim Durchfahren einer Nullposition nicht in den Fahrgastraum geleitet werden können, ist das Stabilisator-Rohr als sogenanntes Sternprofil ausgeführt, welches in Einbuchtungen zwischen Zacken des Sternprofils mit Elastomer ausgefüllt ist, wodurch eine Reduzierung einer Körperschallübertragung in den Fahrgastraum erreicht wird.So that noise caused by the electromechanical actuator of the stabilizer when passing through a zero position can not be directed into the passenger compartment, the stabilizer tube is designed as a so-called star profile, which is filled in indentations between prongs of the star profile with elastomer, thereby reducing a structure-borne sound transmission in the passenger compartment is reached.
Description
Die Erfindung bezieht sich auf einen Stabilisator, insb. einen elektromechanischen Wankstabilisator für ein Kraftfahrzeug nach dem Oberbegriff des Anspruchs 1.The invention relates to a stabilizer, esp. An electromechanical roll stabilizer for a motor vehicle according to the preamble of claim 1.
Aus der
Aufgabe der Erfindung ist es, einen Stabilisator für ein Kraftfahrzeug zu schaffen, mit dem eine Körperschallübertragung in den Fahrzeugaufbau reduzierbar ist.The object of the invention is to provide a stabilizer for a motor vehicle, with which a structure-borne noise transmission in the vehicle body can be reduced.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the features of claim 1. Further advantageous features include the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, dass durch eine optimale Profilform der Stabilisator-Rohre deren Umfangsfläche zur Reduzierung von Körperschall vergrößert wird. Dies wird nach der Erfindung erreicht, indem die Rohrhälften des Stabilisators bzw. des Wankstabilisators im Querschnitt jeweils als Sternprofil ausgebildet sind, das zwischen umfangsseitigen Zacken äußere Einbuchtungen aufweist, die jeweils mit einem Elastomer ausgefüllt sind. Die Einbuchtungen zwischen den Zacken des Sternprofils bilden im ausgefüllten Zustand einen kreisförmigen Querschnitt der Rohrhälften.The advantages achieved by the invention are that is increased by an optimal profile shape of the stabilizer tubes whose peripheral surface to reduce structure-borne noise. This is achieved according to the invention by the tube halves of the stabilizer or the roll stabilizer are each formed in cross section as a star profile having outer recesses between peripheral teeth, which are each filled with an elastomer. The indentations between the teeth of the star profile form a circular cross section of the tube halves in the filled state.
Durch das Sternprofil der Stabilisator-Rohre wird zum einen die Umfangsfläche für eine höhere Federrate vergrößert und zum anderen wird durch das aufgebrachte Elastomer eine deutliche Reduzierung einer Körperschallübertragung in den Fahrgastraum erreicht.Due to the star profile of the stabilizer tubes on the one hand, the peripheral surface is increased for a higher spring rate and on the other hand is achieved by the applied elastomer a significant reduction of a structure-borne sound transmission in the passenger compartment.
Ein elektromechanischer Aktuator des Wankstabilisators zwischen den Stabilisator-Rohren verursacht Störgeräusche, wie ein Klappern durch ein Getriebe im Aktuator und diese Klappergeräusche werden als Körperschall über die Stabilisator-Rohre und eine angebundene Koppelstange in den Fahrgastraum geleitet, welcher durch das auf die Rohrhälften aufgebrachte Elastomer wesentlich reduziert wird.An electromechanical actuator of the roll stabilizer between the stabilizer tubes causes noise such as rattling by a gear in the actuator and these rattling noises are conducted as structure-borne noise via the stabilizer tubes and a tethered coupling rod in the passenger compartment, which is essential by the applied to the tube halves elastomer is reduced.
Insbesondere ist das Elastomer in den Einbuchtungen zwischen den Zacken des Sternprofils der Rohrhälften jeweils aufvulkanisiert. Eine andere Verbindungsart ist ebenfalls denkbar.In particular, the elastomer is vulcanized in the indentations between the teeth of the star profile of the tube halves. Another type of connection is also conceivable.
Ein Ausführungsbeispiel der Erfindung ist den Zeichnungen dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is illustrated in the drawings and will be described in more detail below.
