Description
Die Erfindung betrifft eine Antriebsanordnung für ein Fahrzeug gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a drive arrangement for a vehicle according to the preamble of patent claim 1.
Eine derartige Antriebsanordnung geht beispielsweise aus der
Die erste Antriebswelle kann bei laufendem Verbrennungsmotor infolge eines Radial- oder Winkelversatzes zu der zweiten Antriebswelle und/oder infolge der periodischen Verbrennung Taumelschwingungen ausführen, welche zumindest teilweise durch das im Verbindungsbereich der Wellen vorgesehene elastische Verbindungselement aufgenommen werden. Dabei kann das Verbindungselement bei jedem Umlauf der Kurbelwelle in einer übermäßigen Weise elastisch verspannt werden und es können auf den Eingangsbereich der Kupplung unerwünschte Zwangskräfte einwirken, welche im Laufe der Lebensdauer des Antriebsstranges bzw. des Fahrzeuges zu einer Beeinträchtigung und zu einem vorzeitigen Ausfall der dort angeordneten Komponenten führen kann.The first drive shaft may, with the engine running, due to a radial or angular offset to the second drive shaft and / or due to the periodic combustion perform wobble oscillations, which are at least partially absorbed by the provided in the connection region of the shafts elastic connecting element. In this case, the connecting element during each revolution of the crankshaft in an excessive manner can be elastically braced and it can act on the input portion of the clutch undesirable constraining forces, which in the course of the life of the drive train or the vehicle to an impairment and premature failure of the arranged there Components can lead.
Davon ausgehend ist es Aufgabe der Erfindung, eine Antriebsanordnung der eingangs genannten Art mit einer verbesserten Entkopplung der gegenseitig in Drehmitnahmeverbindung stehenden Baugruppen gegenüber Taumelschwingungen und/oder gegenüber Reaktionskräften infolge eines Radial- oder Winkelversatzes der beteiligten Wellen darzustellen.On this basis, it is an object of the invention to present a drive assembly of the type mentioned with improved decoupling of mutually standing in rotary drive connection assemblies against Taumelschwingungen and / or reaction forces due to a radial or angular displacement of the waves involved.
Die vorstehend genannte Aufgabe wird bei einer gattungsgemäßen Antriebsanordnung durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst.The above object is achieved in a generic drive assembly by the features specified in the characterizing part of claim 1.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den abhängigen Ansprüchen sowie der Figurenbeschreibung entnehmbar.Advantageous embodiments and further developments of the invention can be taken from the dependent claims and the description of the figures.
Gemäß der Erfindung wird eine Antriebsanordnung für ein Fahrzeug vorgeschlagen, welche eine erste Antriebswelle und eine zweite Antriebswelle umfasst, die unabhängig voneinander gelagert sind und zur Drehmomentübertragung miteinander in Verbindung stehen und die weiter eine Trennkupplung beinhaltet, welche mit einem Eingangsbereich mit der ersten Antriebswelle und mit einem Ausgangsbereich mit der zweiten Antriebswelle in Drehmitnahme steht. Dabei ist der Eingangsbereich mittels eines Stützabschnittes und eines Drehentkopplungslagers an der zweiten Antriebswelle gelagert und dort axial festgelegt. Die beteiligten Antriebswellen können insbesondere im Wesentlichen koaxial und axial benachbart zueinander angeordnet sein; wobei beispielweise durch Montage- und/oder Fertigungstoleranzen ein Winkel- und/oder ein Radialversatz der Wellen auftreten kann, so dass deren Drehachsen nicht zusammenfallen.According to the invention, a drive arrangement for a vehicle is proposed, which comprises a first drive shaft and a second drive shaft, which are mounted independently and communicate with each other for torque transmission and further includes a disconnect clutch, which with an input portion with the first drive shaft and an output area with the second drive shaft is in rotational drive. In this case, the input area is supported by means of a support section and a rotary decoupling bearing on the second drive shaft and axially fixed there. The involved drive shafts can in particular be arranged substantially coaxially and axially adjacent to one another; wherein for example by assembly and / or manufacturing tolerances, an angular and / or radial misalignment of the waves may occur, so that their axes of rotation do not coincide.
Gemäß der Erfindung ist bei einer solchen Antriebsanordnung vorgesehen, dass das Drehentkopplungslager gegenüber der zweiten Antriebswelle radial verlagerbar angeordnet ist. Das Drehentkopplungslager kann dabei durch ein Wälzlager gebildet werden, welches mit einem Lagerring radial verlagerbar an der zweiten Antriebswelle anliegt und mit dem anderen Lagerring mit dem Stützabschnitt des Eingangsbereichs der Trennkupplung verbunden ist.According to the invention, it is provided in such a drive arrangement that the rotary decoupling bearing is arranged radially displaceable relative to the second drive shaft. The rotary decoupling bearing can be formed by a roller bearing, which rests with a bearing ring radially displaceable on the second drive shaft and is connected to the other bearing ring with the support portion of the input portion of the separating clutch.
Der Vorteil der Anordnung besteht darin, dass mittels des radial verlagerbaren Lagers eine radiale Einstellung gegenüber der zweiten Antriebswelle in der Weise erfolgen kann, dass ein Radialversatz des Eingangsbereichs der Trennkupplung gegenüber der Drehachse der zweiten Antriebswelle durch eine radiale Einstellbewegung des Drehentkopplungslagers ausgeglichen wird. Dadurch wird vermieden, dass bei einem vorliegenden Radialversatz der Eingangsbereich der Trennkupplung bei jedem Umlauf Ausgleichskräfte aufnehmen und sich periodisch zwangsverformen muss.The advantage of the arrangement is that by means of the radially displaceable bearing a radial adjustment relative to the second drive shaft can be made in such a way that a radial offset of the input portion of the separating clutch with respect to the axis of rotation of the second drive shaft is compensated by a radial adjusting movement of the rotary decoupling bearing. This avoids that in the case of an existing radial offset, the input area of the separating clutch has to absorb compensating forces and periodically forcibly deform with each revolution.
Gemäß einer vorteilhaften Weiterbildung ist in einem gegenseitigen Verbindungsbereich der Antriebswellen eine Ausgleichseinrichtung zum Ausgleich von Taumelbewegungen vorgesehen, welche mit dem Eingangsbereich der Trennkupplung in Drehmitnahme steht. Eine solche Ausgleichseinrichtung kann durch eine Taumelscheibe, z.B. eine Flexplate oder durch eine Federeinrichtung mit Schrauben- oder Blattfedern realisiert werden, welche zur Aufnahme und Absorption von Taumelbewegungen ausgebildet sind. Bei Vorhandensein einer derartigen Ausgleichseinrichtung können wirkende Taumelkräfte somit zu einem wesentlichen Teil bereits im Drehmomentverlauf von einem Verbrennungsmotor kommend bereits vor der Trennkupplung aufgenommen, werden so dass der Eingangsbereich der Trennkupplung im Wesentlichen von solchen Zwangskräften verschont bleibt.According to an advantageous development, a compensating device for compensating wobbling movements is provided in a mutual connecting region of the drive shafts, which is in rotational driving with the input region of the separating clutch. Such compensating means may be constituted by a swash plate, e.g. a flexplate or be realized by a spring device with screw or leaf springs, which are designed for receiving and absorbing tumbling movements. In the presence of such a compensating device, acting tumbling forces can thus already be absorbed in the torque curve by an internal combustion engine already before the separating clutch, so that the input region of the separating clutch essentially remains free of such compulsory forces.
Mit weiterem Vorteil kann der Eingangsbereich der Trennkupplung axial verlagerbar mit der ersten Antriebswelle verbunden sein, was insbesondere mittels einer Steckverzahnung der in Wirkverbindung stehenden Elemente erfolgen kann. Es wird damit ein axialer Ausgleichsbereich bereitgestellt, welcher eine noch weitere verformungsfreie Aufnahme von Taumelkräften ermöglicht, so dass die in diesem Verbindungsbereich in Drehmitnahme stehenden Elemente nicht unerwünscht zwangsverformt werden. Bevorzugt kann in weiterer Ausgestaltung der Eingangsbereich der Trennkupplung radial zu der ersten Antriebswelle festgelegt sein, so dass über normale Bauteiltoleranzen hinausgehend kein weiterer radialer Ausgleich in diesem Verbindungsbereich auftreten kann. Das heißt die Drehmitnahme und die radiale Fixierung des Eingangsbereichs der Trennkupplung erfolgt in einem Verbindungsbereich, der eine axiale Verlagerung der beteiligten Elemente zulässt, während die axiale Fixierung des Eingangsbereichs der Trennkupplung in einem Verbindungsbereich erfolgt, der über das Drehentkopplungslager eine radiale Verlagerung des Eingangsbereichs gegenüber der zweiten Antriebswelle zulässt. With further advantage, the input region of the separating clutch can be axially displaceable connected to the first drive shaft, which can be done in particular by means of a spline of the operatively connected elements. It is thus provided an axial compensation area, which allows even more deformation-free recording of tumbling forces, so that the standing in this connection area in rotary driving elements are not undesirable forcibly deformed. Preferably, in another embodiment, the input region of the separating clutch can be fixed radially to the first drive shaft, so that beyond normal component tolerances no further radial compensation can occur in this connection region. That is, the rotational drive and the radial fixation of the input portion of the separating clutch takes place in a connecting region, which allows an axial displacement of the elements involved, while the axial fixing of the input portion of the separating clutch takes place in a connection region, via the rotary decoupling bearing, a radial displacement of the input area relative to the second drive shaft allows.
Mit besonderem Vorteil kann das Drehentkopplungslager zusätzlich verschwenkbar um ein Verschwenkzentrum angeordnet sein, welches im Wesentlichen auf der Drehachse der zweiten Antriebswelle liegt und in Abhängigkeit von der Einstellung der Radiallage des Drehentkopplungslagers ebenso entsprechend radial gegenüber dieser Drehachse verlagert ist. Der Endbereich dieser Antriebswelle kann dazu beispielsweise eine radial verlagerbares Aufnahmeelement mit einer Kugelkalotte tragen, welche mit einem dazu korrespondierend ausgebildeten Ring des Drehentkopplungslagers zusammenwirkt. Auf diese Weise können insbesondere durch einen Winkel- und/oder Radialversatz der Wellen verursachte Drehungleichförmigkeiten noch besser aufgenommen werden.With particular advantage, the rotary decoupling bearing can additionally be arranged pivotable about a pivoting center, which lies substantially on the axis of rotation of the second drive shaft and is also displaced radially relative to this axis of rotation as a function of the setting of the radial position of the rotary decoupling bearing. For this purpose, the end region of this drive shaft can, for example, carry a radially displaceable receiving element with a spherical cap, which cooperates with a ring of the rotary decoupling bearing designed to correspond thereto. In this way, especially caused by an angular and / or radial displacement of the waves rotational irregularities can be better absorbed.
Als eine günstige Ausgestaltung hat es sich ebenso erwiesen, das Drehentkopplungslager axial vorgespannt an der zweiten Antriebswelle anzuordnen, wodurch eine definierte Axiallage des Drehentkopplungslagers und damit des Eingangsbereichs der Trennkupplung erzielt werden kann.As a favorable embodiment, it has also been found, axially biased to arrange the rotary decoupling bearing on the second drive shaft, whereby a defined axial position of the rotary decoupling bearing and thus the input portion of the separating clutch can be achieved.
Gemäß einer noch weiteren vorteilhaften Ausführungsvariante ist vorgesehen, das Drehentkopplungslager mittels eines axial an der zweiten Antriebswelle anliegenden Aufnahmeelements an dieser anzuordnen. Die Trennkupplung kann dadurch als vormontierte Baueinheit axial mit der zweiten Antriebswelle gefügt werden, wobei das Aufnahmeelement bei der Montage einen Anschlag bildet, so dass die Kupplung an einer vorbestimmten Position axial festgelegt ist. Alternativ kann das Drehentkopplungslager auch beispielweise an einem Radialkragen an der zweiten Antriebswelle zur Anlage gelangen.According to yet another advantageous embodiment variant is provided to arrange the rotary decoupling bearing by means of an axially applied to the second drive shaft receiving element thereto. The separating clutch can be joined as a preassembled unit axially with the second drive shaft, wherein the receiving element forms a stop during assembly, so that the coupling is fixed axially at a predetermined position. Alternatively, the rotary decoupling bearing can also come to rest for example on a radial collar on the second drive shaft.
Nachfolgend wird die Erfindung anhand einer in der Figur dargestellten Ausführungsform beispielhaft erläutert.The invention will be explained by way of example with reference to an embodiment shown in the figure.
