Abstract

The generator for an IC engine is held by lugs within a rubber moulding. The moulding is contained in a split sheet metal holder which can be rotated about attachment bolt fixed to the engine frame. A bolt slides in a link and can be locked in the position required to give the tension required in the driving belt. In this way a substantially flexible mounting is provided which absorbs the vibrations generated by the engine. The generator is protected from inertia forces and the driving belt is not subjected to additional tension.

Schwenkbar gelagerte, riemengetriebene Lichtmaschine für BrennkraftmaschinenPivotable, belt-driven alternator for internal combustion engines

Die Erfindung betrifft eine schwenkbar gelagerte, riemengetriebene Lichtmaschine für Brennkraftmaschinen nach dem Oberbegriff des Anspruchs 1.The invention relates to a pivotably mounted, belt-driven one Alternator for internal combustion engines according to the preamble of claim 1.

Die Schwingbeschleunigung an Lichtmaschinen, insbesondere bei 4-Zylinder-Brennkraftmaschinen ist so hoch, daß die Lichtmaschinen schwingungsgedämpft angeordnet werden müssen. The vibration acceleration on alternators, especially in 4-cylinder internal combustion engines, is so high that the Alternators must be arranged vibration-damped.

Es ist eine Anordnung von Aggregaten an einer Brennkraftmaschine bekannt geworden (P 28 5k 992.0), wobei die Aggregate, wie Lichtmaschine, Lenkhelfpumpe, Kompressor u. dgl. an einem Aggregateträger angeordnet sind, der ohne metallische Verbindung an der Brennkraftmaschine befestigt ist. Zum Nachstellen des Riemenantriebs ist eine Riemenspannrolle vorgesehen.An arrangement of units on an internal combustion engine has become known (P 28 5k 992.0), the units such as alternator, power steering pump, compressor and the like being arranged on a unit carrier which is attached to the internal combustion engine without a metallic connection. A belt tensioning pulley is provided to readjust the belt drive.

Nachteilig an diesem Aggregateträger ist, daß die stoßabsorbierende Schichtstärke der Befestigungspunkte an derThe disadvantage of this subframe is that the shock-absorbing Layer thickness of the attachment points on the

Brennkraftmaschine aus konstruktiven Gründen klein gehalten werden müssen, so daß Erschütterungen von der Brennkraftmaschine, wenn auch in etwas abgedämpfter Form, auf die Lichtmaschine übertragen werden. Hierzu kommen noch die Eigenschwingungen der anderen am Aggregatträger befestigten Aggregate.Internal combustion engine kept small for structural reasons must be so that vibrations from the internal combustion engine, even if in a somewhat dampened form, are transmitted to the alternator. There will be more to this the natural vibrations of the other units attached to the unit carrier.

Aufgabe der Erfindung ist es, Erschütterungen von der Lichtmaschine fernzuhalten. Diese Aufgabe wird durch den kennzeichnenden Teil des Anspruchs 1 gelöst.The object of the invention is to reduce vibrations from the alternator keep away. This task is carried out by the distinctive Part of claim 1 solved.

Die stoßabsorbierende Schicht kann hierbei so dick gewählt werden, daß der gewünschte Effekt erzielt wird. Durch die Erschütterungsfreiheit kann die einmal vorgenommene leichte Spannung des Antriebsriemens lange gehalten werden. Die Klemmung ist von den Schwingungskräften entlastet, die Riemenspanneinrichtung muß keine dynamischen Kräfte aufnehmen und die dazu erforderlichen Teile können leichter gebaut werden.The shock-absorbing layer can be chosen so thick that the desired effect is achieved. Through the The slight tension of the drive belt, once made, can be kept vibration-free for a long time. the The clamping is relieved of the vibration forces, the belt tensioning device does not have to absorb dynamic forces and the parts required for this can be built more easily will.

Ferner kann die Verspannung der Blechschalen durch Federklammern erfolgen. Dadurch ist eine einfache und billige Konstruktion der Blechschalen möglich.Furthermore, the bracing of the sheet metal shells can be done by means of spring clips. This makes it easy and cheap Construction of the sheet metal shells possible.

Schließlich kann die Verspannung der Blechschalen durch mehrere, den Befestigungsflansch bzw. die Befestigungsaugen im Abstand durchsetzende Schrauben definierter, distanzhaltender Spannlänge erfolgen.Finally, the bracing of the sheet metal shells can be achieved by several the mounting flange or the mounting eyes in the Distance enforcing screws more defined, distance maintaining Span length.

Die Schrauben sind an jedem Ende mit je einer Schulter versehen, die in vorbestimmtem Abstand zueinander stehen undThe screws are provided with a shoulder at each end, which are at a predetermined distance from one another and

Diese Verbindung der Blechschalen hat den Vorteil, daß sie leicht und zerstörungsfrei gelöst und wieder verspannt werden kann.keep the pair of metal shells at a distance. The actual thread closes on each shoulder towards the outside at. This connection of the sheet metal shells has the advantage that they are easily and non-destructively loosened and tightened again can be.
