Description
Gebiet der ErfindungTerritory of invention
Die Erfindung bezieht sich auf eine Umschlingungstrieb, insbesondere Steuerungsantrieb für eine Brennkraftmaschine oder eines ihrer Nebenaggregate mit mindestens einem antreibenden Zahnrad und mindestens einem abtreibenden Zahnrad und einer Spann- oder Umlenkrolle und mit einem sie verbindenden Umschlingungsmittel (Zahnriemen oder Kettentrieb), wobei wenigstens eines der Zahnräder (Ausgleichszahnrad) so ausgebildet ist, dass es bei der Rotation dem Trieb eine Ungleichförmigkeit aufprägt mit dem Ziel der Beruhigung des Triebes.The The invention relates to a belt drive, in particular Control drive for an internal combustion engine or one of its ancillaries with at least a driving gear and at least one driven gear and a tensioning or deflection roller and with a belt connecting them (Toothed belt or chain drive), wherein at least one of the gears (compensating gear) is designed so that it during rotation of the shoot a nonuniformity impresses with the aim of calming the instinct.
Hintergrund der Erfindungbackground the invention
Steuerungsantriebe von Brennkraftmaschinen mit einem Kurbelwellen-Antriebsrad, zumindestens einem Nockenwellen-Abtriebsrad und einer Kette oder Zahnriemen oder aber andere an Brennkraftmaschinen vorhandene Aggregatantriebe, sind aufgrund von Drehmomentschwankungen bzw. Winkelgeschwindigkeitsänderung Schwingungsänderungen unterworfen, die in Resonanzbereichen zu hörbaren Geräuschen führen können. Damit verbunden sind erhöhte Reibungskräfte, die die Lebensdauer des Umschlingungstriebes sowie dessen Wirkungsgrad beeinträchtigen können.control drives of internal combustion engines with a crankshaft drive wheel, at least one camshaft driven wheel and a chain or timing belt or other on internal combustion engines existing unit drives, are due to torque fluctuations or angular velocity change vibration changes subjected, which can lead to audible noise in resonance areas. This is associated with increased frictional forces, the the life of the belt drive and its efficiency impair can.
Um
diesen Schwierigkeiten zu begegnen ist bereist vorgeschlagen worden,
wenigstens eines der Räder
so auszubilden, dass es bei der Rotation dem Trieb eine Ungleichförmigkeit
aufprägt,

Zusammenfassung der ErfindungSummary the invention
Der Erfindung liegt daher die Aufgabe zugrunde, einen Umschlingungstrieb der eingangs genannten Art so auszugestalten, dass die an- und abgetriebenen Räder nicht drehpositioniert werden müssen.Of the The invention is therefore based on the object, a belt drive of the type mentioned above in such a way that the on and abiebenen Not wheels must be rotated.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass das Ausgleichszahnrad eine mit einer einen phasenkonstanten Lauf mit dem Umschlingungstrieb sichernden Profilverzahnung für das Umschlingungsmittel versehene Spann- oder Umlenkrolle ist.to solution this object is inventively provided that the compensation gear one with a one phase constant Run with the belt drive locking profile toothing for the belt provided tensioning or deflection roller is.
Durch die Verwendung einer Spann- und Umlenkrolle als Ausgleichszahnrad, was es natürlich erforderlich macht, dass die Spann- oder Umlenkrolle mit einer Verzahnung für das Umschlingungsmittel versehen ist, um den für das Ausgleichszahnrad notwendigen Phasenkonstanten Lauf zu erzielen, der für normale Spann- und Umlenkrollen ja gar nicht erforderlich ist, ergibt sich der Vorteil, dass die an- und abgetriebenen Räder, also speziell das Kurbelwellenrad und das Nockenwellenrad, nicht drehpositioniert werden müssen, sodass die Einrichtung und der Anfangsabgleich des Umschlingungstriebs sich einfacher gestaltet.By the use of a tensioning and deflection roller as a compensation gear, which of course it requires makes that the tensioning or deflection roller provided with a toothing for the belt is to the for the balancing gear necessary to achieve phase constant running the for normal Clamping and deflection rollers are not required at all the advantage that the on and off wheels, so especially the crankshaft and the camshaft sprocket, do not need to be rotationally positioned, so the device and the initial balance of the belt drive makes it easier.
Die als Pulley mit umspritztem Kugellager ausgebildete Spann- oder Umlenkrolle kann dabei entweder mit einem unrunden Teilkreis des Zahnprofils und/oder einem exzentrischen Pulleyablauf versehen sein. In beiden Fällen, und erstrecht natürlich bei der Kombination, können durch periodisch wiederkehrende Vorspannungsvariationen des Umschlingungsmittels, im Allgemeinen eine Zahnriemens, Kraftschwankungen erreicht werden, die bei entsprechender Phasenlage gegenüber den Ungleichmäßigkeiten die von der Brennkraftmaschine ausgehen, zu einem weitgehenden Ausgleich und damit zu einer Beruhigung des Triebes führen können.The designed as Pulley with molded ball bearing clamping or deflection roller can either with a non-circular pitch of the tooth profile and / or an eccentric Pulleyablauf be provided. In both cases and of course, of course the combination, can by periodically recurring bias variations of the belt, in general a timing belt, power fluctuations are achieved the with appropriate phase relation to the irregularities emanating from the internal combustion engine, to a large extent compensation and thus can lead to a reassurance of the instinct.

Die
gezeigte Spannrolle
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Anstelle des exzentrischen Pulleyablaufs könnte auch – gegebenenfalls auch zusätzlich – ein unrunder Teilkreis des Zahnprofils vorgesehen sein derart, dass dieser beispielsweise oval ausgebildet ist, wodurch sich eine Anordnung ergäbe, die speziell für Vierzylindermotoren zur Triebberuhigung geeignet ist. Durch andere polygonale Formen lassen sich entsprechende unrunde Pulleys für andere Zylinderanzahlen der Verbrennungsmaschine realisieren.The Invention is not limited to the illustrated embodiment. Instead of the eccentric Pulleyablaufs could also - possibly in addition - a non-circular Be provided partial circle of the tooth profile such that this example is oval, which would result in an arrangement that especially for Four-cylinder engines for drive calming is suitable. Through others polygonal shapes allow corresponding non-circular pulleys for others Cylinder numbers of the internal combustion engine realize.
Alternativ könnte das Pulley auch aus Sintermetall gefertigt sein.alternative could the pulley can also be made of sintered metal.
