Abstract

The tension rail for a chain drive comprises a support and a covering layer bearing against the chain when installed. This layer (13) is resilient at the area (16) where wear is greatest. At this area the support (10) with layer can form a curved spring component yielding under pressure from the chain, with an aperture (17) in it on the side away from the chain to provide the desired resilience. The elastic area can extend for the first fifth of the layer from the leading edge.

Description

Spannschiene für KettenantriebeTensioning rail for chain drives

Stand der Technik Die Erfindung geht aus von einer Spannschiene für Kettenantriebe nach der Gattung des Hauptanspruchs.PRIOR ART The invention is based on a tensioning rail for Chain drives according to the preamble of the main claim.

Spannschienen werden vor allem in Kraftfahrzeugmotoren verwendet, bei denen die Nockenwelle über eine Steuerkette angetrieben wird. Um die Kette unter einer definierten Spannung zu halten und um Toleranzen und insbesondere das bei längerem Gebrauch auftretende Nachlängen der Kette auszugleichen, wird die Kette über eine Spannschiene, die meist durch Federkraft oder hydraulisch angedrückt wird, gespannt.Slide rails are mainly used in motor vehicle engines, in which the camshaft is driven via a timing chain. To the chain under to keep a defined tension and to tolerances and especially that at The chain will compensate for any length of the chain that occurs after prolonged use via a tensioning rail, which is usually pressed on by spring force or hydraulically, tense.

Bei einer bekannten Spannschiene (DE-OS 24 31 425) besteht die Spannschiene aus einem Träger und einem Gleitbelag, der mit dem Träger mittels einer Steck-, Klemm- oder Schnappverbindung verbunden ist. Der auf dem Träger befestigte Gleitbelag ist aus einem hitzebeständigen Kunststoff, z. B. Polyamid, ausgeführt.In a known tensioning rail (DE-OS 24 31 425) there is a tensioning rail from a carrier and a sliding coating, which is connected to the carrier by means of a plug-in, Clamp or snap connection is connected. The sliding coating attached to the carrier is made of a heat-resistant plastic, e.g. B. polyamide executed.

Nachteilig bei derartigen Spannschienen ist jedoch der relativ hohe Verschleiß insbesondere an gewissen Stellen der Spannschiene.However, the disadvantage of such slide rails is the relatively high Wear especially at certain points on the tensioning rail.

Vorteile der Erfindung Die erfindungsgemäße Anordnung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß eine wesentliche Herabsetzung des Verschleißes des Gleitbelags erzielt wird. Die Erfindung beruht auf der Erkenntnis, daß durch elastisches Angleichen der Spannschiene an die Form der auf sie ablaufenden Kette die Krafteinleitung auf einen größeren Flächenabschnitt der Spannschiene erfolgt. Damit wird die Flächenbelastung, d. h. die Kraft pro Flächeneinheit verringert und damit der Verschleiß des Gleitbelags herabgesetzt.Advantages of the invention The arrangement according to the invention with the characterizing Features of the main claim has the advantage that an essential Reduction of the wear of the sliding lining is achieved. The invention is based on the knowledge that by elastic adjustment of the tensioning rail to the shape the chain running down on it the introduction of force over a larger surface section the tensioning rail takes place. Thus the wing loading, i. H. the force per unit area and thus the wear on the sliding lining is reduced.

Versuche haben ergeben, daß insbesondere der Bereich, auf welchem die Kette auf die Spannschiene aufläuft, besonders verschleißanfällig ist. Erfindungsgemäß wird der Bereich der größten Verschleißzone elastisch ausgeführt, d. h. der Gleitbelag wird als dem Anpreßdruck der Kette ausweichendes Federelement ausgebildet.Tests have shown that in particular the area on which the chain runs onto the tensioning rail, is particularly susceptible to wear. According to the invention the area of the largest wear zone is made elastic, d. H. the sliding surface is designed as a spring element evading the contact pressure of the chain.

Durch die in den Unteransprüchen aufgeführten Maßnahmen ist eine vorteilhafte Weiterbildung und Verbesserung der im Hauptanspruch angegebenen Spannschiene möglich.The measures listed in the subclaims are advantageous Further development and improvement of the tensioning rail specified in the main claim are possible.

Fig. 1 shows a tensioning rail in side view, FIG. 2 a section along the line A-A in Fig. 1.

Beschreibung der Erfindung Die in Fig. 1 dargestellte Spannschiene besteht aus einem als Träger fungierenden Verstärkungsblech 10, dessen verlängerte Oberkante 11 rechtwinklig 'abgebogen ist und in einer Längsnut 12 des Gleitbelags 13 verläuft. Die Längsnut 12 ist so bemessen, daß die abgebogene Kante 11 nahezu spielfrei in ihr geführt ist, d. h. die Nutlänge ist auf die Länge der Kante 11 und die Nuttiefe auf die Breite dieser Kante abgestimmt, wobei die eigentliche Reibfläche des Gleitbelages 13 sicherheitshalber etwas über das Verstärkungsblech 10 übersteht. In Querrichtung stützt sich der Gleitbelag 13 einerseits am Nutgrund und an der als Anschlag wirkenden Seitenfläche des Trägers 10 ab; andererseits ist er mittels keilartigen Vorsprüngen 14 am Gleitbelag in Ausnehmungen 15 der abgebogenen Kante 11 des Verstärkungsbleches 11 verrastet. Die Vorsprünge 14 weisen eine schräg verlaufende Anlauffläche auf, die ein leichtes Einführen der abgebogenen Kante 11 in die Längsnut 12 des Gleitbelages ermöglicht. Hat der Träger 10, 11 seine Einbaulage erreicht, so schnappt die Spitze der Anlauffläche in die Ausnehmung 14 ein und stellt eine in Querrichtung wirkende Verriegelung zwischen dem Verstärkungsblech und dem Gleitbelag her Im übrigen wird bezüglich des Aufbaus der Spannschiene voll Bezug genommen auf den Gegenstand der DE-OS 24 31 425. Description of the Invention The tensioning rail shown in FIG consists of a reinforcing plate 10 acting as a carrier, the extended Upper edge 11 is bent at right angles' and in a longitudinal groove 12 of the sliding lining 13 runs. The longitudinal groove 12 is dimensioned so that the bent edge 11 is almost is guided in it free of play, d. H. the groove length is equal to the length of the edge 11 and the groove depth is matched to the width of this edge, with the actual friction surface of the sliding lining 13 protrudes somewhat beyond the reinforcement plate 10 for safety's sake. In the transverse direction, the sliding lining 13 is supported on the one hand on the groove base and on the acting as a stop side surface of the carrier 10; on the other hand, he is means wedge-like projections 14 on the sliding coating in recesses 15 of the bent edge 11 of the reinforcement plate 11 is locked. The projections 14 have an inclined Contact surface that allows easy insertion of the bent edge 11 into the longitudinal groove 12 of the sliding coating allows. Once the carrier 10, 11 has reached its installation position, so the tip of the contact surface snaps into the recess 14 and provides a interlock acting in the transverse direction between the reinforcement plate and the sliding surface For the rest, full reference is made to FIG the subject of DE-OS 24 31 425.

m Bereich der größten Verschleißzone ist die erfindungsgemäße Spannschiene als elastisches, federndes Element ausgebildet. In Fig. 1 ist dies der Bereich,-auf welchem die Kette auf die Spannschiene aufläuft. Dieser Bereich 16 des Gleitbelages 13 ist ohne Verstärkungsblech ausgeführt, bzw. das Verstärkungsblech 11 wirkt nicht auf den oberen, mit der Kette in Berührung kommenden Gleitbelag ein. Hierfür wurde ein Hohlraum 17 geschaffen, in welchem der Gleitbelag 16 elastisch nachfedern kann.The tensioning rail according to the invention is in the area of the largest wear zone designed as an elastic, resilient element. In Fig. 1, this is the area -on which the chain runs onto the tensioning rail. This area 16 of the sliding lining 13 is designed without a reinforcement plate, or the reinforcement plate 11 does not act on the upper sliding surface that comes into contact with the chain. For this purpose, a cavity 17 was created in which the sliding lining 16 is elastic can rebound.

Der bogenförmig ausgeführte Bereich 16 des Gleitbelages kann demnach bei Belastung durch die Kette in den Bereich 17 ausweichen und somit einem übermäßigen Druck der Kette an einer bestimmten Stelle nachgeben.The arcuate area 16 of the sliding coating can accordingly if the chain is stressed, move to area 17 and thus an excessive one Give in to the pressure of the chain at a certain point.

Bei der erfindungsgemäßen Einrichtung ist es ausreichend, wenn ca. 1/5 der Gesamtlänge des Gleitbelags 13als elastisch, d. h. dem Anpreßdruck nachgebendes Element ausgeführt ist. Dieses Element wird im Bereich der größten Verschleißzone, d. h. im allgemeinen im Auflaufbereich der Kette angeordnet.With the device according to the invention it is sufficient if approx. 1/5 of the total length of the sliding lining 13 as elastic, d. H. yielding to the contact pressure Element is executed. This element is in the area of the largest wear zone, d. H. generally arranged in the run-up area of the chain.

Wie in Fig. 2 dargestellt, ist der Träger bzw. das Verstärkungsblech 11 in einem Steg unterhalb der Ausnehmung 17 angeordnet, um der Spannschiene die notwendige Festigkeit zu vermitteln. Die Befestigungsbohrung 18 befindet sich ebenfalls um'unterhalb der Ausnehmung 17 vorhandenen Steg 19 des Gleitbelags.As shown in Fig. 2, the carrier or the reinforcement plate 11 arranged in a web below the recess 17 to the tensioning rail to convey the necessary strength. The mounting hole 18 is also located around the web 19 of the sliding coating that is present below the recess 17.

Der bogenförmige Bereich 16 des Gleitbelags 13 kann auch nach Art einer Blattreder" ausgebildet sein, d. h. bei Belastung dieses Bereiches erfolgt ein elastisches Nachgeben, um die Flächenbelastung auf den Gleitbelag 13, 16 zu verringern.The arcuate area 16 of the sliding lining 13 can also be made according to Art a leaf spring ", i.e. takes place when this area is loaded elastic yielding in order to increase the surface load on the sliding lining 13, 16 to decrease.
