Abstract
Description
Die Erfindung betrifft einen Nebenaggregate-Antrieb gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an accessory drive according to the preamble of claim 1
Bei Riementrieben von Brennkraftmaschinen ist es bekannt, innerhalb des Verlaufs des das Antriebselement bildenden Riemens wenigstens eine Spannrolle anzuordnen, um unerwünschten Riemenschlupf zu vermeiden und Riemendehnungen zu kompensieren. Der zumindest die Kurbelwelle mit einem Generator verbindende Riemen, der gegebenenfalls mit weiteren Umlenkrollen umgelenkt wird und weitere Sekundärkomponenten treibt, wird an der Spannrolle umgelenkt. Da die Kurbelwelle alle Sekundärkomponenten antreibt, ist die Spannrolle zweckmäßigerweise an der Leertrumseite des Riemens zur Kurbelwelle angeordnet. In der JP-A-2000-230612 ist ein Nebenaggregate-Antrieb mit zwei Spannrollen beschrieben, welche die Belastung des Riemens vermindern. Die Spannrollen sind unmittelbar an die Kurbelwelle angrenzend im Lostrum und im Zugtrum der Kurbelwelle angeordnet.at Driven by internal combustion engines, it is known within the course of the drive element forming belt at least To arrange a tension roller to avoid unwanted belt slippage and compensate for belt strains. The at least the crankshaft with a generator connecting belt, if necessary, with others Deflection rollers is deflected and further secondary components drives, is at the Tension pulley deflected. Since the crankshaft all secondary components drives, the tension roller is expediently on the empty strand side of the belt to the crankshaft. In JP-A-2000-230612 is an ancillary drive with two tension rollers described which reduce the load on the belt. The tension rollers are immediate adjacent to the crankshaft in the Lostrum and in the Zugtrum the crankshaft arranged.
Aufgabe der vorliegenden Erfindung ist es, einen Nebenaggregate-Antrieb zu verbessern und bei einem Lastwechsel die Einkopplung von Schwingungen in das Antriebselement zu vermindern.task The present invention is an accessory drive to improve and at a load change the coupling of vibrations in the drive element to reduce.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.The Task is according to the invention with the features of claim 1.
Bei dem erfindungsgemäßen Nebenaggregate-Antrieb, bei dem eine Kurbelwelle Aggregate über ein biegsames, durch zwei Spannrollen spannbares Antriebselement antreibt, ist zumindest bereichsweise parallel zu dem Antriebselement ein zweites Antriebselement angeordnet. Die beiden Antriebselemente sind mit unterschiedlichen Aggregaten in Antriebsverbindung. Damit kann eine Einkopplung von Schwingungen in das erste Antriebselement, welche von einem vom zweiten Antriebselement angetriebenen Aggregat eingekoppelt werden, vermindert werden. Die zweite Spannrolle entkoppelt die Massenträgheit eines vom zweiten Antriebselement angetriebenen Aggregats, beispielsweise eines Luftkompressors, und reduziert einen Schlupf des ersten Antriebselements. Insbesondere ist mit dem erfindungsgemäßen Nebenaggregate-Antrieb ein Riementrieb auch unter problematischen Randbedingungen realisierbar. So können erhebliche Riemenschwingwege und erheblicher Riemenschlupf, die bei Zuschaltung von relativ großen Trägheitsmassen über ein relativ großes Übersetzungsverhältnis auftreten können, vermieden werden. Von der Kurbelwelle ausgehende Drehschwingungen können sich beispielsweise von einem vom zweiten Antriebselement angetriebenen Kompressor über eine vom ersten Antriebselement angetriebene Wasserpumpe, an der das erste und zweite Antriebselement antriebsmäßig gekoppelt sind, in das erste Antriebselement übertragen. Bevorzugt sind die Antriebselemente Ketten und/oder Riemen.at the accessory drive according to the invention, in which a crankshaft aggregates on a flexible, by two Tension rollers drives tensionable drive element is at least partially arranged parallel to the drive element, a second drive element. The two drive elements are with different aggregates in drive connection. This can be a coupling of vibrations in the first drive element, which of one of the second drive element driven unit can be coupled, can be reduced. The second tension roller decouples the inertia of the second drive element driven aggregate, such as an air compressor, and reduces slippage of the first drive element. Especially is with the auxiliary units drive according to the invention a belt drive can be realized even under problematic boundary conditions. So can significant belt swing paths and significant belt slip that when switching from relatively large Inertia over a relatively large gear ratio occur can, be avoided. From the crankshaft outgoing torsional vibrations can For example, from a driven by the second drive element Compressor over a driven by the first drive element water pump on the the first and second drive elements are drivingly coupled, in the transferred first drive element. The drive elements are preferably chains and / or belts.
