Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Anordnung zum Übertragen einer Antriebsleistung von einer Nockenwelle oder von einer Kurbelwelle auf ein Aggregat einer Brennkraftmaschine, insbesondere auf eine Kraftstoff-Hochdruckpumpe, über ein Rädergetriebe.The invention relates to an arrangement for transmitting a drive power from a camshaft or from a crankshaft to an engine of an internal combustion engine, in particular to a high-pressure fuel pump, via a gear train.
Aus
Zusammenfassung der ErfindungSummary of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, bei einer Anordnung der vorgenannten Art und den mit dieser Anordnung in Verbindung stehenden Bauteilen die Lebensdauer und die Zuverlässigkeit zu erhöhen. Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The invention is therefore based on the object to increase the life and reliability in an arrangement of the aforementioned type and related to this arrangement components. The object is solved by the features of
Es wird vorgeschlagen, zur Reduzierung von Drehmomentschwankungen das Rädergetriebe mit zumindest einem unrunden Rad auszuführen und zugleich das Aggregat in Phasenwinkelversatz zu an der Nockenwelle auftretenden Drehmomentschwankungen antreibbar auszubilden. Durch ein ungleichförmig übersetzendes Rädergetriebe, insbesondere Zahnrad- oder Zugmittelgetriebe, erfährt die Antriebsanordnung Schwingungsanregungen, die aus der unrunden Form der Räder resultieren. Aufgrund der Ausbildung der unrunden Form und der Phasenlage der Antriebselemente lassen sich diese zusätzlichen Anregungen mit den im Betrieb durch das Aggregat verursachten Drehmomentschwankungen überlagern, wodurch letztere ausgelöscht oder zumindest reduziert werden. Überraschenderweise hat sich gezeigt, dass bei einer Kombination dieser Anordnung mit einer weiteren Maßnahme, nämlich durch Antrieb des Aggregats in Phasenwinkelversatz zu an der Nockenwelle auftretenden Drehmomentschwankungen, eine weitere Reduzierung letzterer erreicht wird. Hierbei sind die Winkelstellungen von Aggregateantrieb und Nockenwelle derart aufeinander abgestimmt, dass die Drehmomentschwankungen am Aggregat phasenverschoben zu den Drehmomentschwankungen an der Nockenwelle auftreten. Durch Überlagerung mit den durch die ungleichförmige Übersetzung des Rädergetriebes im Antrieb des Aggregats erzeugten Störungen löschen sich die kumuliert an der Nockenwelle auftretenden Drehmomentschwankungen zumindest teilweise aus. Auf diese Weise können durch Kombination beider vorgenannter Maßnahmen die Belastungen durch Schwingungen sowohl der Nockenwelle als auch des dieser vorgeschalteten Nockenwellenantriebs deutlich reduziert und so die Lebensdauer und Zuverlässigkeit des Antriebsstrangs erhöht werden.It is proposed to carry out the gearbox with at least one non-circular wheel to reduce torque fluctuations and at the same time form the aggregate in phase angle offset to occurring on the camshaft torque fluctuations drivable. By a non-uniform translating gear train, in particular gear or traction mechanism, the drive assembly undergoes vibrational excitations, resulting from the non-circular shape of the wheels. Due to the formation of the non-circular shape and the phase position of the drive elements, these additional suggestions can be superimposed with the torque fluctuations caused during operation by the unit, whereby the latter are extinguished or at least reduced. Surprisingly, it has been found that in a combination of this arrangement with a further measure, namely by driving the unit in phase angle offset to occurring on the camshaft torque fluctuations, a further reduction of the latter is achieved. Here, the angular positions of the unit drive and camshaft are coordinated so that the torque fluctuations on the unit out of phase with the torque fluctuations occur on the camshaft. By superimposing with the interference generated by the non-uniform gear ratio of the gear train in the drive of the unit, the cumulative occurring at the camshaft torque fluctuations extinguish at least partially. In this way, by combining both aforementioned measures, the loads due to vibrations of both the camshaft and the camshaft drive connected upstream thereof can be significantly reduced and thus the service life and reliability of the drive train can be increased.
Vorzugsweise ist das Rädergetriebe als formschlüssiges ungleichmäßig übersetzendes Getriebe, insbesondere als Zahnradgetriebe ausgebildet. Bevorzugt weist dieses ein mit der Nockenwelle oder der Kurbelwelle in Antriebsverbindung stehendes unrund ausgebildetes Zahnrad und ein aggregateseitig in Antriebsverbindung stehendes unrund ausgebildetes Zahnrad auf.Preferably, the gear train is designed as a form-fitting non-uniformly translating gear, in particular as a gear transmission. Preferably, this has a non-circular gear formed in drive connection with the camshaft or the crankshaft and a non-circular gear formed in drive connection on the aggregate side.
Alternativ kann das Rädergetriebe als Zugmittelgetriebe ausgebildet sein, das ein mit der Nockenwelle oder der Kurbelwelle in Antriebsverbindung stehendes Zahnriemen- oder Kettenrad und ein aggregateseitig in Antriebsverbindung stehendes Zahnriemen- oder Kettenrad aufweist. Eine Reduzierung der vom Aggregat erzeugten Drehmomentschwankungen lässt sich dabei auf einfache Weise unmittelbar erreichen, indem nur das aggregateseitige Zahnriemen- oder Kettenrad unrund ausgebildet ist. Denkbar ist aber auch, nur das nockenwellenseitig oder kurbelwellenseitig antreibende Zahnriemen- oder Kettenrad unrund auszuführen. Schließlich ist es auch möglich, sowohl das aggregateseitige Zahnriemen- oder Kettenrad als auch das nockenwellenseitige Riemen- oder Kettenrad unrund auszubilden.Alternatively, the gear train may be designed as a traction mechanism having a toothed belt or sprocket in drive connection with the camshaft or the crankshaft and a toothed belt or sprocket in drive connection on the aggregate side. A reduction of the torque fluctuations generated by the unit can be achieved directly in a simple manner by only the aggregate-side toothed belt or sprocket is formed out of round. It is also conceivable that only the camshaft side or crankshaft side driving toothed belt or sprocket run out of round. Finally, it is also possible to make non-circular both the aggregate-side toothed belt or sprocket and the camshaft-side belt or sprocket.
Weiterhin ist es auch denkbar, das Aggregat über ein mehrstufiges Rädergetriebe, insbesondere ein mehrstufiges Zahnrad- oder Zugmittelgetriebe, von der Nockenwelle oder der Kurbelwelle anzutreiben, wobei das Rädergetriebe in einer oder in mehreren oder in allen seiner Stufen jeweils zumindest ein unrundes Rad aufweist. Furthermore, it is also conceivable to drive the unit via a multi-stage gear train, in particular a multi-stage gear or traction mechanism, of the camshaft or the crankshaft, wherein the gear train in one or more or in all its stages each having at least one non-circular wheel.
Durch das Maß der Unrundheit der Umfangsprofile der Zahn-, Ketten- oder Riemenräder kann das Maß der Ungleichförmigkeit der Übersetzung und damit die Amplitude der am Rädergetriebe erzeugten Störung bzw. Drehmomentschwankung eingestellt werden. Dabei verstärkt eine größere Amplitude der am Rädergetriebe erzeugten Störung bzw. Drehmomentschwankung den Überlagerungseffekt mit den am Aggregat sowie an der Nockenwelle erzeugten Störungen.Due to the degree of out-of-roundness of the circumferential profiles of the toothed, chain or belt wheels, the degree of nonuniformity of the ratio and thus the amplitude of the disturbance or torque fluctuation generated at the gearbox can be adjusted. In this case, a larger amplitude of the noise generated at the gearbox or torque fluctuation amplifies the overlay effect with the noise generated at the unit and on the camshaft.
Bevorzugt ist zumindest ein rotatorisches Antriebselement des Aggregats in Drehwinkelversatz zur Nockenwelle angeordnet. Vorzugsweise wird dabei die Winkelstellung im Antriebssystem des Aggregats derart gewählt, dass die im Betrieb vom Aggregat erzeugten Drehmomentschwankungen phasenverschoben zu den Drehmomentschwankungen an der Nockenwelle auftreten und sich zumindest teilweise auslöschen.Preferably, at least one rotary drive element of the unit is arranged in rotational angle offset from the camshaft. Preferably, the angular position in the drive system of the unit is selected such that the torque fluctuations generated during operation of the unit occur in phase with the torque fluctuations on the camshaft and extinguish themselves at least partially.
Zum Antrieb einer Kraftstoff-Hochdruckpumpe kann beispielsweise ein Antriebsrad oder zumindest ein Pumpennocken mit Drehwinkelversatz zu zumindest einem Ventilnocken der Nockenwelle zur Betätigung zumindest eines Gaswechselventils der Brennkraftmaschine angeordnet werden. Dabei wird die Winkelstellung des Antriebsrads oder des Pumpennockens in Bezug auf den Ventilnocken derart gewählt, dass die an der Kraftstoff-Hochdruckpumpe auftretenden Drehmomentschwankungen und die aufgrund der Ventilbetätigung von dem Ventilnocken erzeugten Drehmomentschwankungen sich zumindest teilweise auslöschen.For driving a high-pressure fuel pump, for example, a drive wheel or at least one pump cam with angular displacement to at least one valve cam of the camshaft for actuating at least one gas exchange valve of the internal combustion engine can be arranged. In this case, the angular position of the drive wheel or of the pump cam with respect to the valve cam is selected such that the torque fluctuations occurring at the high-pressure fuel pump and the torque fluctuations produced by the valve cam due to the valve actuation cancel out at least partially.
