Abstract
Description
Gebiet der ErfindungTerritory of invention
Die Erfindung bezieht sich auf eine Umschlingungstrieb von Brennkraftmaschinen für kraftschlüssig an- oder abtreibende Nebenaggregate mit periodisch wiederkehrenden Momentenschwankungen, insbesondere für Kolbenkompressoren.The The invention relates to a belt drive of internal combustion engines for non-positive or abortive ancillary units with periodically recurring torque fluctuations, especially for Reciprocating compressors.
Hintergrund der Erfindungbackground the invention
Steuerungsantriebe von Brennkraftmaschinen mit einem Kurbelwellen-Antriebsrad, zumindest einem Nockenwellen-Abtriebsrad und einer Kette oder einem Zahnriemen, oder aber andere an Brennkraftmaschinen vorhandene Aggregatantriebe, sind aufgrund von Drehmomentschwankungen bzw. Winkelgeschwindigkeitsänderungen Schwingungsänderungen unterworfen, die in Resonanzbereichen zu hörbaren Geräuschen führen können. Damit verbunden sind erhöhte Reibungskräfte, die die Lebensdauer des Umschlingungstriebs sowie dessen Wirkungsgrad beeinträchtigen können.control drives of internal combustion engines with a crankshaft drive wheel, at least one camshaft output gear and a chain or a timing belt, or other on internal combustion engines existing unit drives, are due to torque fluctuations or angular velocity changes vibration changes subjected, which can lead to audible noise in resonance areas. Associated with it increased Frictional forces, the life of the belt drive and its efficiency impair can.

wenigstens eines der Räder
so auszubilden, dass es bei der Rotation dem Trieb eine Ungleichförmigkeit
aufprägt,
wobei dies bei der
Zusammenfassung der ErfindungSummary the invention
An dieser Möglichkeit fehlt es allerdings, wenn es um Umschlingungstriebe für an- oder abtreibende Nebenaggregate geht, die lediglich kraftschlüssig, das heißt Luft behaftet über Poly-V-Scheiben angetrieben werden, wobei ein Keilrippenriemen verwendet wird, der nicht quer zur Laufrichtung verlaufende Zähne, sondern in Laufrichtung verlaufende Profilrippen aufweist.At this possibility However, it is missing when it comes to wrap around for or abortive ancillaries goes, the only non-positively, the is called Air tainted over Poly-V discs are driven using a V-ribbed belt is, not the teeth running transversely to the direction, but Having running in the direction of profile ribs.
Um auch für derartige kraftschlüssig, das heißt schlupfbehaftete Übertragungen ohne Synchronisation einen Drehmomentausgleich zu erzielen, ist erfindungsgemäß vorgesehen, dass das an- oder abtreibende Rad des Nebenaggregats, also beispielsweise eines Klimakompressors oder einer Lenkhilfepumpe derart unrund ausgebildet ist, dass die dadurch dem Trieb aufgeprägte Ungleichförmigkeit die Momentenschwankungen zumindest teilweise kompensiert, was im einfachsten Fall derart erfolgen kann, dass das unrunde Rad äquidistant verteilte Erhebungen aufweist, wobei die Zahl der Erhebungen der Periodenzahl der Momentenschwankungen entsprechen.Around also for such frictional, this means slippage transfers is to achieve torque compensation without synchronization provided according to the invention, that the driving or abreibendem wheel of the accessory, so for example an air compressor or a power steering pump trained so out of round is that the unevenness thereby imposed on the instinct the torque fluctuations at least partially compensated for what happened in the The simplest case can be done such that the non-circular wheel equidistant distributed surveys, with the number of surveys of the Period number of the torque fluctuations correspond.
Je nach Art der Momentenschwankungen, die durch die Ungleichmäßigkeiten aufgrund der Kurvenbewegung der Nebenaggregate hervorgerufen werden, kann dabei in Ausgestaltung der Erfindung vorgesehen sein, dass die Erhebungen des unrunden Rades gegenüber den Momentenschwankungen des Nebenaggregats vor- oder nachlaufend versetzt sind, um auf diese Art und Weise eine optimale Triebberuhigung erzielen zu können.ever according to the type of torque fluctuations caused by the irregularities can be caused due to the curve movement of the ancillaries, can be provided in an embodiment of the invention that the surveys the non-round wheel opposite the torque fluctuations of the ancillary leading or trailing are staggered in order to achieve optimum sedation in this way to achieve.
