Hintergrund der Erfindung The present invention relates to a tensioning device for tensioning a traction means of an internal combustion engine, with a rotatably mounted end rail, the rear side facing away from the traction means is formed with a bearing surface extending on the internal combustion engine to form a tapered towards the pivot point of the rail space, and a pressure-loaded slide, which is acted upon by the force of a spring along the contact surface in the direction of rejuvenation of the space. Background of the invention
Eine Spannvorrichtung gemäß der vorgenannten Gattung ist aus der Druckschrift JP 2009257455 A bekannt. Die Schrift zeigt eine Spannvorrichtung zum Ausgleich von Längungen eines Zugmittels mit einer endseitig drehpunktgela- gerten Schiene, wobei zwischen der Schiene und einer Anlagefläche eines Verbrennungsmotors ein mit Federkraft beaufschlagter Schieber angeordnet ist. Die Anlagefläche und die Schiene bilden einen sich zum Drehpunkt der Schiene hin verjüngenden Raum aus. Die Feder, welche den Schieber in die Verjüngungsrichtung des Raumes schiebt, ist als Druckfeder ausgebildet. Die Druckfeder stützt sich mit ihrem einen Ende an einer zusätzlichen Anlagefläche des Verbrennungsmotors ab und mit ihrem anderen Ende an dem Schieber. A clamping device according to the aforementioned type is known from JP 2009257455 A. The document shows a tensioning device to compensate for elongations of a traction device with a rail end point drehpunktgela-, wherein between the rail and a contact surface of an internal combustion engine, a spring loaded with a slider is arranged. The contact surface and the rail form a space that tapers towards the pivot point of the rail.

Aufgabe der Erfindung Der Erfindung liegt die Aufgabe zugrunde, eine kostengünstige und montagefreundliche Spannvorrichtung bereitzustellen. Zusammenfassung der Erfindung OBJECT OF THE INVENTION The object of the invention is to provide a cost-effective and easy-to-install clamping device. Summary of the invention
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine Feder mit ihrem ersten Federende am drehpunktseitigen Ende der Schiene und mit ihrem zwei- ten Federende an dem Schieber fixiert ist. Der besondere Vorteil dabei ist, dass keine zusätzliche Anlagefläche am Verbrennungsmotor angebracht werden muss. Die Spannvorrichtung kann als ein komplettes Bauteil geliefert und montiert werden. Eine bevorzugte Weiterbildung der Erfindung sieht vor, dass die Schiene zwei an ihre Rückseite angrenzende Seitenflächen besitzt, wovon zumindest eine eine Führungslasche aufweist, welche in zumindest eine in den Schieber seitlich eingebrachte, längsverlaufende Führungsnut eingreift. Dadurch wird eine seitliche Verschiebung oder eine Verdrehung des Schiebers verhindert. Eine kostengünstige Herstellung der Spannvorrichtung sieht vor, sowohl die Schiene als auch den Schieber aus Kunststoff mittels Spritzgießverfahren herzustellen. The object is achieved in that a spring is fixed with its first spring end at the pivot point end of the rail and with its second end of the spring to the slide. The particular advantage of this is that no additional contact surface must be attached to the internal combustion engine. The clamping device can be delivered and assembled as a complete component. A preferred embodiment of the invention provides that the rail has two adjacent to its rear side surfaces, of which at least one has a guide tab, which engages in at least one laterally introduced into the slide, longitudinal guide groove. As a result, a lateral displacement or rotation of the slider is prevented. A cost-effective production of the clamping device provides to produce both the rail and the slide made of plastic by injection molding.
In bevorzugter Ausgestaltung der Erfindung handelt es sich bei der Feder, welche den Schieber in Verjüngungsrichtung des Raumes zieht, um eine Zugfeder. Nach einer Weiteren bevorzugten Ausgestaltung der Erfindung ist es vorgesehen, dass die Schiene zwischen dem drehpunktgelagerten Schienenende und einem gegenüberliegenden Schienenende einen konvexen, in Richtung der Anlagefläche verlaufenden Vorsprung aufweist. Der Vorsprung ist dazu ausgebildet, mit der Anlagefläche den sich zum Drehpunkt der Schiene hin verjün- genden Raum auszubilden. Eine durch den Verbrennungsprozess der Brennkraftmaschine ausgelöste Drehungleichförmigkeit verursacht in einer hohen Frequenz einen Wechsel von Beschleunigungsphasen und Verzögerungsphasen, welche zu einer oszillierenden Bewegung des Zugmittels führen. Um die Schwingungen des Zugmittels zu dämpfen wird eine aus flexiblem Material hergestellte Schiene eingesetzt. Um dennoch eine ausreichende Steifigkeit der Schiene zu erreichen, sollte die Schiene partiell verstärkt werden. Der konvex verlaufende Vorsprung an der Rückseite der Schiene erhöht die Steifigkeit der Schiene, so dass ein übermäßiges Durchbiegen bei Druckbelastung vermieden wird. In a preferred embodiment of the invention, it is in the spring, which pulls the slider in the direction of rejuvenation of the space to a tension spring. According to a further preferred embodiment of the invention, it is provided that the rail between the pivot-mounted rail end and an opposite rail end has a convex, extending in the direction of the contact surface projection. The projection is designed to form with the contact surface the space tapering towards the pivot point of the rail. A rotational irregularity triggered by the combustion process of the internal combustion engine causes, at a high frequency, a change of acceleration phases and deceleration phases, which lead to an oscillating movement of the traction means. In order to dampen the vibrations of the traction means, a rail made of flexible material is used. In order nevertheless to achieve sufficient rigidity of the rail, the rail should be partially reinforced. The convex protrusion on the back of the rail increases the stiffness of the rail Rail, so that excessive bending under pressure is avoided.

Detaillierte Beschreibung der Zeichnungen Figur 1 zeigt eine schematische Darstellung eines Zugmitteltriebes eines Verbrennungsmotors, welcher ein Antriebsrad 12, ein Abtriebsrad 13 und ein die beiden Räder umschlingendes Zugmittel 2 aufweist. Auf Grund von Verschleiß kann es zur Längung des Zugmittels 2 kommen. Die Längung muss durch ein Nachspannen des Zugmittels 2 mittels einer wie in Figur 1 darge- stellten Spannvorrichtung 1 kompensiert werden. Die Spannvorrichtung 1 weist eine endseitig drehpunktgelagerte Schiene 3 auf. Auf der Vorderseite der Schiene 3 gleitet das Zugmittel 2 entlang. Die Rückseite der Schiene 3 bildet zusammen mit einer Anlagefläche 8 des Verbrennungsmotors einen sich, in Richtung des Drehpunktes 14 der Schiene 3 hin, verjüngenden Raum aus. An der Rückseite der Schiene 3 ist ein zusätzlicher Vorsprung 9 zwischen dem drehpunktgelagerten Schienenende 6a und einem gegenüberliegenden Schienenende 6b angeordnet. Der Vorsprung 9 verläuft in Richtung der Anlagefläche 8, wodurch der Raum zwischen Schiene 3 und Anlagefläche 8 zusätzlich ver- jüngt wird. Zwischen dem Vorsprung 9 und der Anlagefläche 8 ist ein Schieber 7 beweglich angeordnet, wobei der Schieber 7 sowohl den Vorsprung 9 als auch die Anlagefläche 8 berührt. Der Schieber 7 ist außerdem über eine Zugfeder 4 mit dem drehpunktgelagerten Schienenende 6a verbunden, wodurch der Schieber 7 in Richtung des Drehpunkts 14 der Schiene 3 kraftbeaufschlagt ist. DETAILED DESCRIPTION OF THE DRAWINGS FIG. 1 shows a schematic illustration of a traction mechanism drive of an internal combustion engine, which has a drive wheel 12, a driven wheel 13 and a traction mechanism 2 that wraps around the two wheels. Due to wear, it can come to the elongation of the traction means 2. The elongation must be compensated by a tensioning of the traction means 2 by means of a tensioning device 1 as shown in FIG. The tensioning device 1 has an end pivotally mounted rail 3. On the front of the rail 3, the traction means 2 slides along. The back of the rail 3, together with a contact surface 8 of the internal combustion engine, a, in the direction of the pivot point 14 of the rail 3 out, tapered space. At the back of the rail 3, an additional projection 9 between the pivot-mounted rail end 6a and an opposite rail end 6b is arranged. The projection 9 extends in the direction of the contact surface 8, as a result of which the space between the rail 3 and the contact surface 8 is additionally reinforced. is getting younger. Between the projection 9 and the abutment surface 8, a slider 7 is movably arranged, wherein the slider 7 contacts both the projection 9 and the abutment surface 8. The slider 7 is also connected via a tension spring 4 with the pivot-mounted rail end 6a, whereby the slide 7 is subjected to a force in the direction of the pivot point 14 of the rail 3.
Im Weiteren wird die Funktionsweise der Spannvorrichtung 1 näher erläutert. Das Zugmittel 2 drückt im gespannten Zustand gegen die Schiene 3. Die Schiene 3 wiederum drückt gegen den an der Anlagefläche 8 anliegenden Schieber 7. Der Schieber 7 wird solange in seiner Position gehalten, solange die auf ihn wirkenden Reibungskräfte, welche abhängig von der auf die Schiene 3 wirkende Kraft sind, höher sind, als die auf den Schieber 7 wirkende Zugkraft der Feder 4. Erst wenn sich das Zugmittel 2 längt und die auf die Schiene 3 wirkende Kraft abnimmt, verringern sich die Reibungskräfte und, der Schieber 7 wird mittels Federkraft in Verjüngungsrichtung des Raumes gezogen. Der Schieber 7 ist keilförmig ausgebildet, wobei sein verjüngtes Ende in Richtung des Drehpunkts 14 der Schiene 3 zeigt. Da sich der kraftbeaufschlagte Schieber 7 zwischen Anlagefläche 8 und Rückseite der Schiene 3 drängt, schwenkt die Schiene 3 um Ihren Drehpunkt 14 in Richtung des zu spannenden Zugmittels 2. Das daraufhin gespannte Zugmittel 2 drückt erneut gegen die Schiene 3. Die von der Schiene 3 auf den Schieber 7 übertragene Kraft bewirkt eine Erhöhung der Reibungskräfte am Schieber 7, so dass dieser in einer neuen Position gehalten wird. Auf diese Weise ist ein dynamisches und stufenloses Nach- spannen des Zugmittels 2 möglich. Furthermore, the operation of the tensioning device 1 will be explained in more detail. The traction means 2 presses in the tensioned state against the rail 3. The rail 3 in turn presses against the voltage applied to the contact surface 8 slide 7. The slide 7 is held in position as long as long as the frictional forces acting on him, which depends on the on Rail 3 acting force are higher than the force acting on the slide 7 tensile force of the spring 4. Only when the traction means 2 lengthens and the force acting on the rail 3 decreases, the frictional forces decrease and, the slide 7 is by spring force drawn in the rejuvenation direction of the room. The slide 7 is wedge-shaped, with its tapered end pointing in the direction of the pivot point 14 of the rail 3. Since the force-loaded slide 7 between contact surface 8 and back of the rail 3, the rail 3 pivots about its pivot point 14 in the direction of tensioning means to be tensioned 2. The then tensioned pulling means 2 presses again against the rail 3. The of the rail 3 the slider 7 transmitted force causes an increase in the friction forces on the slide 7, so that it is held in a new position. In this way, a dynamic and continuous tensioning of the traction means 2 is possible.
Figur 2 zeigt eine erfindungsgemäße Weiterbildung der in Figur 1 beschriebenen Spannvorrichtung 1 . Der Schieber 7 der Spannvorrichtung 1 wird in diesem Ausführungsbeispiel zusätzlich linear geführt. Die Linearführung weist eine Führungslasche 1 1 auf, welche seitlich an der Schiene 3 angeordnet ist und dabei in Richtung des Schiebers 7 verläuft. Die Führungslasche 1 1 greift seitlich in die Führungsnut 10 ein und verhindert somit, dass der Schieber 7 den Reibkontakt zur Schiene 3 oder dem Vorsprung 9 verliert. Figur 3 zeigt die in Figur 2 beschriebene Linearführung in einer Schnittdarstellung. Die Schiene 3 weist in diesem Ausführungsbeispiel zwei Führungslaschen 1 1 auf, die seitlich in zwei dafür vorgesehene Führungsnuten 10 des Schiebers 7 eingreifen. Durch diese Anordnung wird gewährleistet, dass der Vorsprung 9 der Schiene 3 flächig an dem Schieber 7 anliegt und eine Verdrehung des Schiebers 7 vermieden wird. FIG. 2 shows a development according to the invention of the tensioning device 1 described in FIG. The slider 7 of the tensioning device 1 is additionally guided linearly in this embodiment. The linear guide has a guide lug 1 1, which is arranged laterally on the rail 3 and thereby extends in the direction of the slide 7. The guide tab 1 1 engages laterally in the guide groove 10 and thus prevents the slide 7 loses the frictional contact with the rail 3 or the projection 9. Figure 3 shows the linear guide described in Figure 2 in a sectional view. The rail 3 has in this embodiment, two guide plates 1 1, which laterally engage in two provided for this purpose guide grooves 10 of the slider 7. By this arrangement it is ensured that the projection 9 of the rail 3 rests flat against the slider 7 and a rotation of the slider 7 is avoided.
