Description

Die Erfindung bezieht sich auf die Anordnung eines Generators am Maschinengehäuse einer Brennkraftmaschine, deren Kurbelwelle über einen Riementrieb mit einer auf der Generatorwelle sitzenden Riemenscheibe verbunden ist.The invention relates to the arrangement of a generator on Machine housing of an internal combustion engine, the crankshaft via a belt drive with one on the generator shaft seated pulley is connected.

Insbesondere bei leistungsstarken Generatoren entsteht ein Körperschall, der durch eine Schwingungsanregung der Lager­ schilde z. B. durch magnetische Kräfte erzeugt wird und der über die Motorlager in die Fahrzeugkarosserie geleitet wird und sich durch erhebliche Geräusche bemerkbar machen kann. Eine nahe­ liegende Lösung dieses Problems würde darin bestehen, den Generator über elastische Lager mit dem Maschinengehäuse zu verbinden. Hier tritt nun aber das Problem auf, daß eine derartige elastische Lagerung, die verhältnismäßg weich sein muß, keine exakte Fluchtung der Riemenscheibe gewährleistet, die beispielsweise beim Antrieb durch einen Keilrippenriemen gefordert werden muß und die Riemenkräfte die elastischen Lager beeinflussen, z. B. durch Verspannen der Lager die Übertragung des Körperschalls begünstigen.A particularly arises with powerful generators Structure-borne noise caused by vibration excitation of the bearings shields z. B. is generated by magnetic forces and the the engine mount is directed into the vehicle body and itself can make itself noticeable by considerable noise. A close The solution to this problem would lie in the Generator via elastic bearings with the machine housing too connect. Here, however, the problem arises that a such elastic storage that be relatively soft must, no exact alignment of the pulley ensures that for example when driving with a V-ribbed belt must be required and the belt forces the elastic bearings influence, e.g. B. by tightening the bearings, the transfer of Favor structure-borne noise.

Demzufolge liegt der Erfindung die Aufgabe zugrunde, eine Anordnung zu schaffen, mit der einerseits der im Generator erzeugte Körperschall von dem Maschinengehäuse ferngehalten und andererseits eine exakte Fluchtung der Riemenscheibe erreicht wird.Accordingly, the invention is based on the object To create an arrangement with the one hand in the generator generated structure-borne noise kept away from the machine housing and on the other hand, an exact alignment of the pulley is achieved becomes.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruches 1 angegebenen Merkmale gelöst.This object is achieved by the in the characteristics of Features specified claim 1 solved.

Durch die akustisch entkoppelte Befestigung des Generators am Maschinengehäuse, normalerweise mittels üblicher Gummi-Metall- Lagerbüchsen wird die Übertragung von Körperschall vom Generator auf das Maschinengehäuse und über dieses auf die Fahrzeug­ karosserie wirksam unterbunden. Dadurch, daß die Riemenscheibe jedoch am Motorgehäuse oder an einem mit diesem verbundenen Lagerschild und damit in dem gleichen Bauteil gelagert ist, das auch die Kurbelwelle und die auf dieser sitzende Riemenscheibe aufnimmt, sind Fluchtungsfehler, die sonst durch die weiche elastische Lagerung des Generators entstehen könnten, ausge­ schlossen und die Einwirkung der Riemenkräfte auf die elastische Lagerung wird verhindert. Durch die elastische Kupplung zwischen Riemenscheibe und Generatorwelle wird diese Beweglichkeit des Generators nicht beeinträchtigt. Due to the acoustically decoupled attachment of the generator on Machine housing, usually using conventional rubber-metal Bearing bushes are the transmission of structure-borne noise from the generator on the machine housing and via this on the vehicle body effectively prevented. Because the pulley however on the motor housing or on one connected to it End shield and thus is stored in the same component that also the crankshaft and the pulley sitting on it are misalignments that are otherwise caused by the soft elastic storage of the generator could arise out closed and the impact of the belt forces on the elastic Storage is prevented. Due to the elastic coupling between Pulley and generator shaft this mobility of the Generator is not affected.  

Um zu gewährleisten, daß die elastische Kupplung beim Anbau des Generators am Maschinengehäuse absolut spannungsfrei ist, ist es zweckmäßig, die Riemenscheibe drehbar an einem Lagerschild zu lagern, das mit dem Maschinengehäuse einstellbar verbunden ist.To ensure that the flexible coupling when mounting the Generator on the machine housing is absolutely free of tension, it is Expedient to turn the pulley on a bearing plate store that is adjustably connected to the machine housing.

Das Lager der Riemenscheibe sollte vorzugsweise in der Mittel­ ebene der Riemenscheibe liegen, um die Lagerbelastung zu minimieren, damit ein möglichst kleines Lager verwendet werden kann. Zu diesem Zweck kann das Lagerschild einen rohrförmigen Lagerfortsatz aufweisen, während die Nabe der Riemenscheibe von zwei konzentrisch ineinander angeordneten Ringen gebildet ist, die einseitig miteinander verbunden sind und zwischen denen sich der Lagerfortsatz erstreckt, wobei der innere Ring in dem Lager­ fortsatz gelagert ist und der äußere Ring mit dem Riemen zusammenwirkt und wobei der innere Ring durch das elastische Kupplungsglied mit der Generatorwelle verbunden ist. Dabei kann sich die Generatorwelle durch den inneren Ring hindurch erstrecken und an ihrem Ende eine erste Kupplungsscheibe tragen, die über ein elastisches Zwischenglied mit einer zweiten Kupplungsscheibe verbunden ist, die auf das freie Ende des inneren Ringes aufgeschraubt. Diese zweite Kupplungsscheibe kann gleichzeitig zur axialen Fixierung des zwischen dem inneren Ring und dem Lagerfortsatz angeordneten Wälzlagers verwendet werden. The bearing of the pulley should preferably be in the middle level of the pulley to increase the bearing load minimize so that the smallest possible bearing is used can. For this purpose, the end shield can be tubular Bearing extension have, while the hub of the pulley two concentrically arranged rings are formed, which are connected on one side and between which there are the bearing extension extends with the inner ring in the bearing is continuously stored and the outer ring with the belt interacts and with the inner ring through the elastic Coupling member is connected to the generator shaft. It can the generator shaft through the inner ring extend and carry a first clutch disc at its end, which has an elastic intermediate link with a second Clutch disc is connected to the free end of the screwed on the inner ring. This second clutch disc can at the same time for axially fixing the between the inner ring and the bearing extension arranged roller bearing can be used.  

Zwei Ausführungsbeispiele der Erfindung werden im folgenden unter Bezugnahme auf die Zeichnungen beschrieben. Es zeigt:Two embodiments of the invention are as follows described with reference to the drawings. It shows:

Fig. 1 eine Vorderansicht eines am Maschinengehäuse einer Brennkraftmaschine angebrachten Generators, Fig. 1 is a front view of a mounted on the engine housing of an internal combustion engine generator,

Fig. 2 eine Seitenansicht des Generators von Fig. 1, teilweise geschnitten und Fig. 2 is a side view of the generator of Fig. 1, partially in section and

Fig. 3 die Lagerung und Ankoppelung der Riemenscheibe an die Generatorwelle in einer zweiten Ausführungsform, wobei die obere Hälfte geschnitten dargestellt ist. Fig. 3 shows the storage and coupling of the pulley to the generator shaft in a second embodiment, the upper half being shown in section.

Es sei zunächst auf die Fig. 1 und 2 Bezug genommen, in denen mit 1 das Maschinengehäuse (Zylinderkurbelgehäuse) einer Brennkraftmaschine bezeichnet ist, an dem ein Generator 2 über Lagerstellen 3, 4 und 5 befestigt ist. Die Lager 3, 4 und 5 sind übliche elastische Lager mit einer inneren und einer äußeren Büchse 6 bzw. 7 und einer elastischen Zwischenlage 8. Durch die elastischen Lager wird der im Generator 2 erzeugte Körperschall vom Maschinengehäuse 1 ferngehalten.Reference is first made to FIGS. 1 and 2, in which 1 denotes the machine housing (cylinder crankcase) of an internal combustion engine, to which a generator 2 is fastened via bearing points 3 , 4 and 5 . The bearings 3 , 4 and 5 are conventional elastic bearings with an inner and an outer sleeve 6 and 7 and an elastic intermediate layer 8 . The structure-borne noise generated in the generator 2 is kept away from the machine housing 1 by the elastic bearings.

Der Antrieb des Generators 2 erfolgt in üblicher Weise von der Kurbelwelle der Brennkraftmaschine über einen Keilrippen­ riemen 9, der eine mit der Generatorwelle 10 verbundene Riemen­ scheibe 11 antreibt. Um zu vermeiden, daß die durch die elastischen Lager ermöglichten Bewegungen des Generators 2 die Fluchtung der Riemenscheibe 11 in Bezug auf die auf der Kurbel­ welle sitzende Riemenscheibe beeinträchtigt und die Riemenkräfte auf die elastische Lager beeinflussen, ist die Riemenscheibe 11 nicht wie üblich starr, sondern über eine elastische Kupplung 15 auf der Generatorwelle 10 befestigt und über ein Lager 12 an einem Lagerschild 13 gelagert, das durch Schrauben 14 einstel­ lbar am Maschinengehäuse 1 befestigt ist. Da somit die Riemenscheibe 11 in oder an dem gleichen Bauteil gelagert ist, in dem die Kurbelwelle mit ihrer Riemenscheibe gelagert ist, ist eine exakte Fluchtung der beiden Riemenscheiben sichergestellt und ein Einwirken der Riemenkräfte auf die elastische Lagerung vermieden. Die Übertragung des Drehmoments von der Riemenscheibe 11 auf die Generatorwelle 10 erfolgt mittels der elastischen Kupplung 15, die z. B. aus einem Elastomer-Ring besteht, der einerseits an der Riemenscheibe 11 und andererseits an einer Hülse 16 anvulkanisiert ist, welche auf der Generatorwelle 10 befestigt ist. Die elastische Kupplung 15 ermöglicht es dem Generator 2, sich im Rahmen der Elastizität seiner Lager 3, 4 und 5 zu bewegen und sie bildet auch eine akustische Abkopplung der Generatorwelle 10 von dem Maschinengehäuse 1. The drive of the generator 2 takes place in the usual manner from the crankshaft of the internal combustion engine via a V-ribbed belt 9 , which drives a belt pulley 11 connected to the generator shaft 10 . In order to avoid that the movements of the generator 2 made possible by the elastic bearings impair the alignment of the pulley 11 with respect to the pulley seated on the crankshaft and influence the belt forces on the elastic bearings, the pulley 11 is not rigid as usual, but rather mounted on the generator shaft 10 via a flexible coupling 15 and mounted through a bearing 12 on a bearing plate 13 which is secured by screws 14 to the machine housing Adjustab Ibar. 1 Since the pulley 11 is thus mounted in or on the same component in which the crankshaft is supported with its pulley, an exact alignment of the two pulleys is ensured and an impact of the belt forces on the elastic mounting is avoided. The torque is transmitted from the pulley 11 to the generator shaft 10 by means of the elastic coupling 15 , which, for. B. consists of an elastomer ring which is vulcanized on the one hand on the pulley 11 and on the other hand on a sleeve 16 which is fixed on the generator shaft 10 . The elastic coupling 15 enables the generator 2 to move within the elasticity of its bearings 3 , 4 and 5 and also forms an acoustic decoupling of the generator shaft 10 from the machine housing 1 .

In Fig. 3, in der gleiche oder gleichartige Teile wie in den Fig. 1 und 2 mit dem gleichen Bezugszeichen, jedoch mit einem Strich, bezeichnet sind, weist die Riemenscheibe 11′ zwei konzentrisch ineinander angeordnete Ringe 17 und 18 auf, die einseitig miteinander verbunden sind und zwischen sich einen Ringraum 19 begrenzen, in die sich ein rohrförmiger Lagerfort­ satz 20 erstreckt, der an das Lagerschild 13′ beispielsweise angeschweißt ist. Das Lager 12′ ist zwischen dem inneren Ring 18 und dem Lagerfortsatz 20 angeordnet. Die Generatorwelle 10′ erstreckt sich durch den inneren Ring 18 hindurch und trägt eine erste Kupplungsscheibe 21, die über ein elastisches Zwischen­ glied 22 mit einer zweiten Kupplungsscheibe 23 verbunden ist, welche auf den inneren Ring 18 aufgeschraubt ist und gleich­ zeitig das Lager 12′ axial fixiert. Der hier nicht gezeigte Keilrippenriemen läuft auf dem äußeren Ring 17. Der Vorteil dieser Ausführung besteht darin, daß das Lager 12′ in der Mittelebene der Riemenscheibe 11′ liegt und somit geringen Belastungen ausgesetzt ist.In Fig. 3, in the same or similar parts as in Figs. 1 and 2 with the same reference numerals, but with a dash, are designated, the pulley 11 'has two concentrically arranged rings 17 and 18 , the one side with each other are connected and between them define an annular space 19 into which a tubular bearing extension 20 extends, which is welded to the end shield 13 ', for example. The bearing 12 'is arranged between the inner ring 18 and the bearing extension 20 . The generator shaft 10 'extends through the inner ring 18 and carries a first clutch disc 21 which is connected via an elastic intermediate member 22 to a second clutch disc 23 which is screwed onto the inner ring 18 and at the same time the bearing 12 ' axially fixed. The V-ribbed belt, not shown here, runs on the outer ring 17 . The advantage of this embodiment is that the bearing 12 'is in the central plane of the pulley 11 ' and is therefore exposed to low loads.

Um zu erreichen, daß die elastische Kupplung 15 bzw. 22 beim Einbau nicht vorgespannt wird, ist das Lagerschild 13 bzw. 13′, wie vorher erwähnt, einstellbar am Maschinengehäuse 1 befestigt. Zu diesem Zweck sind die Löcher 24 (Fig. 2) im Lagerschild 13, durch welches sich die Schrauben 14 erstrecken, als Langlöcher oder mit einem so großen Durchmesser ausgebildet, daß erforderliche Verstellungen des Lagerschildes 13 ermöglicht werden.In order to ensure that the elastic coupling 15 or 22 is not prestressed during installation, the end shield 13 or 13 ', as previously mentioned, is adjustably attached to the machine housing 1 . For this purpose, the holes 24 ( FIG. 2) in the bearing plate 13 , through which the screws 14 extend, are designed as elongated holes or with a diameter so large that necessary adjustments of the bearing plate 13 are made possible.
