Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Nebenaggregat eines Verbrennungsmotors, das mit einem Triebrad verbunden ist, wobei das Triebrad einen mit einem Zugmittel in Wirkverbindung stehenden Laufmantel und eine mit einer Antriebsachse des Nebenaggregats drehfest verbundene Nabe aufweist, sowie eine zwischen dem Laufmantel und der Nabe wirksam angeordnete Dämpfungseinrichtung zur Verminderung von Drehschwingungen.The The invention relates to an accessory of an internal combustion engine, the is connected to a drive wheel, wherein the drive wheel with a traction means operatively connected running jacket and one with a drive axle the accessory rotatably connected hub, and an intermediate the running jacket and the hub effectively arranged damping device for the reduction of torsional vibrations.
Hintergrund der ErfindungBackground of the invention
Zur
Vermeidung unerwünschter Drehschwingungen ist es bekannt,
bei einem Nebenaggregat eines Verbrennungsmotors, beispielsweise
bei einem Generator, ein Triebrad der genannten Art einzusetzen.
Die
Die
Bei den vorbekannten Nebenaggregaten, die mit den genannten Triebrädern versehen sind, stellt der zur Verfügung stehende Bauraum mitunter ein Problem dar. Je nach dem zu übertragenden Drehmoment bzw. der zu übertragenden Leistung vom Zugmittel auf das Nebenaggregat muss das Triebrad eine gewisse Größe aufweisen, die in manchen Fällen Schwierigkeiten hervorruft. Das gilt speziell für den axialen und radialen Bauraum, der wegen des Übersetzungsverhältnisses bzw. des begrenzten Frontbauraums nicht immer zur Verfügung steht.at the previously known ancillary units, with the said drive wheels provided, provides the available space sometimes a problem. Depending on the transfer Torque or the power to be transmitted from the traction means on the accessory, the drive wheel must be a certain size which causes difficulties in some cases. This is especially true for the axial and radial space, because of the translation ratio or the limited space is not always available.
Aufgabe der ErfindungObject of the invention
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Nebenaggregat samt Triebrad der eingangs genannten Art so fortzubilden, dass es möglich ist, die benötigte Funktionalität des Triebrads in geringerem Bauraum unterzubringen.Of the present invention is based on the object, an accessory along with drive wheel of the type mentioned in such a way that it possible, the required functionality to accommodate the drive wheel in a smaller space.
Zusammenfassung der ErfindungSummary of the invention
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass die Nabe des Triebrads mit dem Laufmantel unter Zwischenschaltung der Dämpfungseinrichtung mittels einer Welle verbunden ist, die sich zumindest teilweise durch das Nebenaggregat erstreckt.The Solution of this problem by the invention is characterized in that that the hub of the drive wheel with the running jacket with interposition the damping device connected by means of a shaft is that extends at least partially through the accessory.
Vorzugsweise erstreckt sich die Welle vollständig durch das Nebenaggregat.Preferably The shaft extends completely through the accessory.
Die Welle ist dabei bevorzugt konzentrisch zur Antriebsachse des Nebenaggregats angeordnet, wobei die Antriebsachse hohlzylindrisch ausgebildet ist.The Shaft is preferably concentric with the drive axis of the auxiliary unit arranged, wherein the drive axle is formed as a hollow cylinder.
Die Nabe des Triebrads ist gemäß einer bevorzugten Ausgestaltung der Erfindung mit der Dämpfungseinrichtung drehfest und/oder. unmittelbar verbunden, wobei die Dämpfungseinrichtung mit der Welle drehfest und/oder unmittelbar verbunden ist. Die Welle ist in diesem Falle vorzugsweise mit dem Laufmantel drehfest und/oder unmittelbar verbunden.The Hub of the drive wheel is according to a preferred Embodiment of the invention with the damping device rotatable and / or. directly connected, wherein the damping device is rotatably and / or directly connected to the shaft. The wave is in this case preferably non-rotatable with the barrel jacket and / or directly connected.
Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass die Nabe des Triebrads und der Laufmantel des Triebrads an sich gegenüberliegenden axialen Enden des Nebenaggregats angeordnet sind.A preferred embodiment of the invention provides that the hub of the drive wheel and the running mantle of the drive wheel itself opposite axial ends of the accessory are arranged.
Wie an sich bekannt, kommt vorzugsweise eine Dämpfungseinrichtung mit einem Federspeicher zum Einsatz.As known per se, is preferably a damping device with a spring accumulator for use.
Die Welle kann in der Antriebsachse des Nebenaggregats mittels mindestens eines Lagers gelagert sein. Hierbei kommt bevorzugt ein Nadellager zum Einsatz.The Shaft can in the drive axle of the accessory by means of at least be stored a warehouse. In this case, a needle bearing is preferred Commitment.
Bei dem Nebenaggregat handelt es sich bevorzugt um einen Generator für die Fahrzeug-Stromerzeugung.at The auxiliary unit is preferably a generator for the vehicle power generation.
Mit der vorgeschlagenen Ausgestaltung eines Nebenaggregats samt Triebrad wird es möglich, im Vergleich mit vorbekannten Lösungen den benötigten Bauraum zu reduzieren, so dass die in Rede stehende Funktionalität der Dämpfung von Drehschwingungen auch dann eingesetzt werden kann, wenn die Raumverhältnisse ungünstig sind.With the proposed embodiment of an accessory including drive it becomes possible compared with previously known solutions to reduce the required space, so that in question Functionality of the damping of torsional vibrations can also be used when the space are unfavorable.
