Die Erfindung betrifft ein Zahnriemenrad mit einem Zahnkranz nach dem Oberbegriff des Anspruchs 1.The The invention relates to a toothed belt wheel with a ring gear after Preamble of claim 1.

Die Geräuschemission eines solchen Zahnriemengetriebes mit Zahnriemenrad aus einem metallischen Werkstoff ist nicht minimiert.The noise Such a belt drive with toothed belt from a metallic Material is not minimized.

Die Dissertationsschrift "Geräuschverhalten und Geräuschminderung von Zahnriementrieben", U. Jansen, TU Aachen, Fortschritt-Berichte VDI Nr. 136, befasst sich mit der systematischen Erforschung von möglichen Geräuschursachen an Zahnriementrieben und die Gewichtung der Ursachen in relevante und weniger relevante Ursachen. Die Schallemission wurde in Abhängigkeit einer großen Zahl von Auslegungs- und Betriebsparametern untersucht. Die Dissertationsschrift belegt, dass die Drehzahl von Zahnriemenrädern und -scheiben und die Riemenbreite alle anderen Einflüsse von Auslegungs- und Betriebsparametern von Zahnriementrieben übersteigen. Die Zahnriemenbreite bestimmt dabei das Frequenzgebiet, in dem die Schallenergie abgestrahlt wird. Mit zunehmender Riemenbreite sinkt die Frequenz maximaler Pegel.The Dissertationsschrift "Noise behavior and noise reduction of timing belt drives ", U. Jansen, TU Aachen, Progress Reports VDI No. 136, deals with the systematic investigation of possible noise causes of toothed belt drives and the weighting of causes in relevant and less relevant Causes. The sound emission was dependent on a large number examined by design and operating parameters. The dissertation proves that the speed of pulleys and pulleys and the Belt width all other influences of design and operation parameters of timing belt drives. The timing belt width determines the frequency range in which the Sound energy is radiated. With increasing belt width decreases the frequency of maximum levels.
Als Ursache für das Betriebsgeräusch von Zahnriementrieben gelten der Zahneingriffsstoß, Zahnriemen-Transversalschwingungen, Luftausströmungen der in Eingriff kommenden Zahnlücke, Drehzahl und Riemengeschwindigkeit und die Zahneingriffsfrequenz. Deutlich höhere Pegel werden an Zahnriemenscheiben gemessen im Vergleich zu der freien Trumlänge, die mit Ausnahme von Riemenresonanz als abstrahlendes Element des Zahnriemens weitgehend ausgeschlossen werden kann.When Cause for the operating noise of toothed belt drives apply the tooth meshing, toothed belt transversal vibrations, Luftausströmungen the tooth gap coming in, Speed and belt speed and the meshing frequency. Significantly higher Levels are measured on timing pulleys compared to the free strand length, with the exception of belt resonance as the radiating element of Timing belt can be largely excluded.
Unmittelbar beim Riemeneinlauf treten die maßgeblichen Pegel auf, wobei ein merklicher Unterschied zwischen Antriebsseite und Abtriebsseite des Zahnriemens nicht besteht. Das Zahnriemengeräusch wird zum überwiegenden Teil durch das Aufschlagen des Zahnriemens auf Zahnriemenradteile im Zahneingriff des treibenden Zahnriemenrades aber auch, was neuere Untersuchungen belegen, durch Körperschall verursacht.immediate at the belt inlet, the relevant levels occur, with a noticeable difference between the drive side and output side the timing belt does not exist. The toothed belt noise is overwhelming Part by the toothed belt hitting toothed belt parts in the meshing of the driving pulley but also what's newer Studies prove, by structure-borne noise caused.
Die Dissertationsschrift schlägt zur Geräuschdämpfung eines vollmetallischen Zahnriemenrades vor, axiale Flächen des Zahnriemenrades mit Schallschluckmasse zu versehen. Es ergeben sich dadurch aber kaum verbesserte akustische Verhältnisse.The Dissertationsschrift proposes for noise reduction of a full metallic timing belt before, axial surfaces of the timing belt with Sound absorption mass to provide. However, this hardly results improved acoustic conditions.

Der Erfindung liegt die Aufgabe zugrunde, auf einfache Weise realisierbare, flexibel anwendbare wirkungsvolle Geräuschdämpfungsmaßnahmen an Zahnriemengetrieben vorzuschlagen.Of the Invention is based on the object, in a simple manner feasible, flexibly applicable effective noise damping measures on toothed belt transmissions propose.
Die Aufgabe wird mit einem Zahnriemenrad mit den Merkmalen des Anspruchs 1 gelöst.The Task is with a toothed belt with the features of the claim 1 solved.
Dadurch, dass ein Zahnriemenrad mit einem Zahnkranz geschaffen ist, das zumindest aus einem ersten Element und einem zweiten Element besteht und die Elemente in Umfangsrichtung und in axialer Richtung des Zahnriemenrades vollständig gegeneinander abgegrenzt sind, wobei die Elemente drehfest miteinander verbunden sind und ein Element aus einem Nichtmetall-Werkstoff, wie etwa einem Kunststoff, und ein Element aus einem Metall-Werkstoff gebildet ist, ist eine wirkungsvolle konstruktive Maßnahme vorgesehen, Körperschall durch Umleitung und/oder Unterbrechung an dem Zahnriemenrad zu minimieren.Thereby, that a toothed belt with a ring gear is created, at least consists of a first element and a second element and the Elements in the circumferential direction and in the axial direction of the toothed belt wheel Completely are delimited against each other, wherein the elements rotatably connected to each other and an element of a non-metal material, such as a Plastic, and an element formed from a metal material is, an effective design measure is provided, structure-borne noise by diversion and / or interruption to minimize the timing belt.

Ist das Zahnriemenrad als Antriebsritzel auf einer Motorwelle eines Servomotors eines Lenksystems angeordnet, so lässt sich auf, im Vergleich zum Stand der Technik, besonders einfache Weise der Körperschall eines Zahnriemengetriebes des Lenksystems minimieren. Es kann zweckmäßig sein, das Zahnriemenrad aus mehr als zwei Elementen zu bilden und etwa, in radialer Richtung des Zahnriemenrades betrachtet, Elemente aus Metall-Werkstoff abwechseln mit Elementen aus Nichtmetall-Werkstoff abwechselnd drehfest miteinander zu verbinden und ein Zahnriemenrad zu bauen oder mit Hilfe von Spritzgusstechnik zu formen.is the timing pulley as a drive pinion on a motor shaft of a Servo motor of a steering system arranged so can be opened, in comparison to the prior art, particularly simple way the structure-borne sound of a Minimize the belt drive of the steering system. It may be appropriate to make the toothed belt wheel of more than two elements and about, viewed in the radial direction of the belt pulley, elements off Metal material alternates with elements of non-metal material alternately rotatably connect with each other and to build a toothed belt or with the help of injection molding technology.
In einem besonders bevorzugten Ausführungsbeispiel des Zahnriemenrades ist ein Element als Nabe des Zahnriemenrades und ein Element als Zahnkranz des Zahnriemenrades zusammengefügt, wobei bevorzugt nicht die Nabe aus einem Nichtmetall-Werkstoff wie etwa aus einem Duroplast oder Thermoplast oder ein Elastomer, wie etwa ein Mischgummi mit geringer Shore-Härte ist.In a particularly preferred embodiment of the toothed belt wheel is an element as a hub of the toothed belt wheel and an element as a ring gear of the toothed belt wheel joined together, wherein does not prefer the hub of a non-metal material such as from a thermoset or thermoplastic or an elastomer, such as is a mixed rubber with low Shore hardness.
Bevorzugt ist das Zahnriemenrad aus einer Stahlnabe und einem darum gespritzten oder gepressten Kunststoffzahnkranz gebildet. Es kann auch anstelle des Kunststoffzahnkranzes ein Sintermetallzahnkranz oder ein Stahlzahnkranz vorgesehen sein, wobei zwischen dem Zahnkranz und der Stahlnabe eine Elastomerschicht angeordnet ist, die die Schallausbreitung über das Zahnriemenrad unterbricht.Prefers the timing belt pulley is made of a steel hub and sprayed around it or pressed plastic ring gear formed. It can also be instead of the plastic sprocket a sintered metal sprocket or a steel sprocket be provided, wherein between the sprocket and the steel hub an elastomeric layer is arranged, the sound propagation over the Timing belt wheel interrupts.
Es kann auch zweckmäßig sein, zwischen der Stahlnabe und dem Kunststoffzahnkranz des Zahnriemenrades eine Elastomerschicht anzuordnen.It may also be appropriate between the steel hub and the plastic toothed ring of the toothed belt wheel to arrange an elastomeric layer.
