Description

Die Erfindung betrifft die Kurbelwelle eines Motors mit zumindest zwei Abtrieben, die auf einem gemeinsamen Wellenabschnitt mittels einer im wesentlichen axial gerichteten Spannkraft gegeneinander verspannt sind. Insbesondere betrifft die Erfindung in diesem Zusammenhang Kurbelwellen mit einer Riemenscheibe und einem Kettenrad als Abtrieb, wie diese zum Betrieb von Ölpumpen, Nockenwellen, Lichtmaschinen und ähnlichem bei Kraftfahrzeugen Verwendung finden.The invention relates to the crankshaft of an engine with at least two Driven on a common shaft section by means of a in essential axially directed clamping force are braced against each other. In particular, the invention relates in this context Crankshafts with a pulley and a sprocket as output, like these for the operation of oil pumps, camshafts, alternators and similar find in motor vehicles use.

Bei derartigen Anordnungen, insbesondere bei Kettenrädern, die eine Nockenwelle und ähnliches antreiben, ist die Relativposition der Abtriebe auf der Kurbelwelle von entscheidender Bedeutung. Einerseits muss diese Relativposition in geeigneter Weise festgelegt sein, damit die Nockenbewegung mit der übrigen Motorbewegung hinreichend in Phase verläuft. Insbesondere dürfen während des Motorbetriebes sich diese Einstellungen auch bei größeren Belastungen nicht verändern. Aus diesem Grunde wurden bis dato derartige Abtriebe mittels Formschlusses an der Kurbelwelle befestigt.In such arrangements, in particular sprockets, the one Drive camshaft and the like, is the relative position of the outputs on the crankshaft crucial. On the one hand, this must be Relative position to be set appropriately, so that the Cam movement with the rest of the motor movement sufficiently in phase runs. In particular, these may during engine operation Do not change settings even with larger loads. For this Basically, such outputs were by means of positive connection to the Attached crankshaft.

Andererseits sollte auch eine Justiermöglichkeit bestehen, insbesondere um ein Spiel oder Montageungenauigkeiten ausgleichen zu können. Bei einem Formschluss zwischen Welle und Abtrieben ist dieses nur mit sehr großem Aufwand möglich. On the other hand, there should also be an adjustment option, in particular to be able to compensate for a game or assembly inaccuracies. at a positive connection between shaft and drives this is only very great effort possible.

Um die Montage zu erleichtern, ist es bekannt, ein Kettenrad sowie eine Riemenscheibe mittels einer Spannmutter gegen eine Wellenschulter zu verspannen (siehe Figur 3). Während eine derartige Verspannung ausreicht, die Abtriebe auf der Kurbelwelle während des Normalbetriebes des Motors zu fixieren, können Drehmomentspitzen dazu führen, daß die Abtriebe gegenüber der Kurbelwelle in Umfangsrichtung verlagert werden. Hierdurch gelangen Kurbelwelle und Abtrieb außer Phase, was zu einer Zerstörung des entsprechenden Motors führen kann.To facilitate the assembly, it is known a sprocket and a Pulley by means of a clamping nut against a shaft shoulder brace (see Figure 3). While such a strain sufficient, the outputs on the crankshaft during normal operation To fix the engine, torque peaks can cause the Outputs relative to the crankshaft shifted in the circumferential direction become. As a result, the crankshaft and output go out of phase, which can lead to destruction of the corresponding engine.

Zum radialen Verspannen eines Abtriebs schlägt die GB 2 013 835 A vor, innerhalb einer zur Kurbelwelle liegenden Aussparung des Abtriebs Keilringpaare vorzusehen, die beim axialen Verspannen zweier Abtriebe gegeneinander zu einer radialen Verkeilung eines Abtriebsrades führen.For radial bracing of an output, GB 2 013 835 A proposes within a recess of the output lying to the crankshaft Keilringpaare to be provided, which in the axial clamping of two drives against each other lead to a radial wedging of a driven wheel.

Es ist Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Anordnung bereitzustellen, welche mit einfachen mechanischen Mitteln eine besonders sichere Verspannung mehrerer Abtriebe auf variable Weise ermöglicht.It is an object of the present invention to provide a generic arrangement which is a particularly simple mechanical means safe clamping of multiple drives in a variable manner.

Als Lösung schlägt die Erfindung eine Kurbelwelle mit den Merkmalen des Anspruchs 1 vor.As a solution, the invention proposes a crankshaft with the features of claim 1 before.

Durch die Umlenkmittel wirken auf die Abtriebe sowie auf die Welle Radialkräfte, die eine wesentlich höhere Verspannung dieser beiden Baugruppen bedingen. Hierdurch können wesentlich höhere Drehmomente ausgeübt werden, sodass diese Anordnung auch bei einem Auftreten von Drehmomentspitzen die beiden Baugruppen ausreichend miteinander fixiert.By the deflection acting on the outputs as well as on the shaft radial forces, which is a much higher tension condition these two modules. This can be much higher Torques are exercised, so that this arrangement even at a Occurrence of torque peaks, the two modules sufficient fixed together.

Insbesondere ist es vorteilhaft, wenn die Spannkraft mit ihrer radialen Komponente sowohl auf einen der Abtriebe als auch auf die Kurbelwelle selbst wirkt. Hierdurch wird dessen Fixierung in Umfangsrichtung weiter erhöht.In particular, it is advantageous if the clamping force with its radial Component on one of the outputs as well as on the crankshaft itself acts. As a result, its fixation in the circumferential direction continues elevated.

Vorteilhafterweise sind das Spannelement bzw. die Umlenkmittel zwischen den beiden Abtrieben angeordnet, sodass durch eine einzige zusätzliche Baugruppe der erwünschte Effekt erreicht werden kann. Dies ermöglicht eine verhältnismäßig kostengünstige Realisierung der Erfindung.Advantageously, the clamping element or the deflection means arranged between the two drives, so that by a single additional assembly of the desired effect can be achieved. This allows a relatively inexpensive realization of Invention.

Darüber hinaus können die Umlenkmittel bzw. das Spannelement einstückig mit einem der Abtriebe verbunden und mit dem konusförmigen Bereich in einer entsprechenden Ausnehmung des anderen Abtriebs angeordnet sein. Hierdurch kann auf eine zusätzliche, separate Baugruppe zu Gänze verzichtet werden. Die Umlenkmittel bzw. das Spannelement werden an dem jeweiligen Abtrieb lediglich geeignet ausgeformt. Dieses trägt zu einer weiteren Kostenreduktion einerseits bei der Herstellung und andererseits bei der Montage bei.In addition, the deflection or the clamping element integrally connected to one of the power take-offs and to the cone-shaped one Area in a corresponding recess of the other output be arranged. This allows for an additional, separate assembly completely waived. The deflection or the clamping element are only suitably formed at the respective output. This contributes to a further cost reduction on the one hand in the production and on the other hand, during assembly.

Darüber hinaus kann einer der Abtriebe an seiner den Umlenkmitteln bzw. dem Spannelement abgewandten Seite an einer Wellenschulter anliegen. Hierdurch ist eine genaue axiale Positionierung dieses Abtriebes bezüglich der Kurbelwelle gewährleistet. Letztere Anordnung eignet sich insbesondere für Kettenräder, die in axialer Richtung genau positioniert sein sollten, um einen runden Lauf der Ketten zu gewährleisten. Eine neben einem Kettenrad angeordnete Riemenscheibe hingegen kann auf einen konusartigen Bereich eines Spannelementes aufgleiten, da bei einer Riemenscheibe eine exakte axiale Positionierung nicht zwingend erforderlich ist. Es versteht sich, dass die Verwendung einer derartigen Wellenschulter nicht zwingend auf die vorbeschriebenen Baugruppen bzw. die vorbeschriebene Anordnung beschränkt ist. Vielmehr kann diese auch für andere Arten von Abtrieben Verwendung finden.In addition, one of the drives at its the deflection or abut the clamping element facing away from the side of a shaft shoulder. As a result, an accurate axial positioning of this output with respect the crankshaft guaranteed. The latter arrangement is suitable especially for sprockets that are accurately positioned in the axial direction should be to ensure a smooth running of the chains. A in contrast to a sprocket arranged pulley, however, can on slip on a cone-like portion of a clamping element, as in a Pulley does not necessarily require exact axial positioning is required. It is understood that the use of such Shaft shoulder not necessarily on the above assemblies or the above-described arrangement is limited. Rather, this can also be for other types of power take-offs.

In the crankshafts shown in the figures are two outputs, namely sprockets 2, 2 ', 2 "and pulleys 3, 3' 'on one Shaft journal of a crankshaft 1 by means of a clamping screw 4 and a Washer 5 braced against a shaft shoulder 6.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel ist zwischen dem Kettenrad 2 und der Riemenscheibe 3 als Spannelement ein Spannring 7 angeordnet. Dieser weist zwei konusförmige bzw. kegelartige Bereiche auf, die in entsprechenden Ausnehmungen des Kettenrades 2 bzw. der Riemenscheibe 3 angeordnet sind.In the embodiment shown in Figure 1 is between the Sprocket 2 and the pulley 3 as a clamping element a clamping ring. 7 arranged. This has two cone-shaped or conical areas on, in corresponding recesses of the sprocket 2 and the Pulley 3 are arranged.

Um ein Aufbringen der radialen Spannkräfte zu erleichtern, ist bei den hier vorliegenden Ausführungsbeispielen der Spannring mit Mitteln versehen, die ein radiales Verlagern der konusförmigen Bereiche ermöglichen.To facilitate application of the radial clamping forces, is in the here present embodiments of the clamping ring with means provided, which is a radial displacement of the cone-shaped areas enable.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel wird dieses dadurch realisiert, dass der Spannring 7 geschlitzt ausgebildet ist. Wird bei dieser Anordnung die Spannschraube 4 angezogen, so laufen sowohl das Kettenrad 2 als auch die Riemenscheibe 3 auf dem Spannring 7 auf und dieser wird komprimiert. Hierdurch werden Spannkräfte mit einer radialen Komponente bereitgestellt.In the embodiment shown in Figure 1 this is characterized realized that the clamping ring 7 is slotted. Will be at this Arrangement tightened the clamping screw 4, so run both the Sprocket 2 and the pulley 3 on the clamping ring 7 and this one is compressed. As a result, clamping forces with a radial Component provided.

Bei dem in Figur 2 dargestellten Ausführungsbeispiel sind an dem Kettenrad 2' Spannlippen 7' mit konusförmigen Bereichen vorgesehen, die in die entsprechende Ausnehmung der Riemenscheibe 3 hineinkragen. Dadurch, dass die Spannlippen 7' voneinander getrennt sind, können auch diese in gewissen Grenzen radial auf die Welle 1 hinbewegt werden. Hierdurch wird eine radiale Verspannung ermöglicht. In the embodiment shown in Figure 2 are on the Sprocket 2 'clamping lips 7' provided with conical areas, the in the corresponding recess of the pulley 3 protrude. The fact that the clamping lips 7 'are separated from each other, can also These are moved radially to the shaft 1 within certain limits. As a result, a radial tension is made possible.

Die Verspannung erfolgt bei diesen Ausführungsbeispielen sowohl hinsichtlich der Kurbelwelle 1 als auch hinsichtlich der Abtriebe 2, 2', 3, wodurch eine besonders hohe Fixierung gewährleistet ist.The bracing takes place both in these embodiments with regard to the crankshaft 1 as well as with regard to the power take-offs 2, 2 ', 3, whereby a particularly high fixation is guaranteed.

Bei den in den Figuren 1 und 2 dargestellten, erfindungsgemäßen Ausführungsbeispielen betragen die Winkel der Spannelemente 7, 7' bzw. der entsprechenden Ausnehmungen vorzugsweise zwischen 15° und 30°.In the illustrated in Figures 1 and 2, inventive Embodiments are the angle of the clamping elements 7, 7 'and the corresponding recesses preferably between 15 ° and 30 °.

Durch diese Anordnungen lassen sich Drehmomente zu 2000 Nm übertragen, während bei einer vergleichbaren Anordnung nach dem Stand der Technik (siehe Figur 3), bei welcher die Spannschraube 4 gleichermaßen angespannt ist jedoch nur axiale Spannkräfte auftreten, die Drehmomentübertragung auf 400 Nm beschränkt ist.These arrangements allow torques of 2000 Nm transferred, while in a comparable arrangement according to the state the technique (see Figure 3), in which the clamping screw. 4 equally strained but only axial clamping forces occur, the Torque transmission is limited to 400 Nm.
