Gebiet der ErfindungTerritory of invention
Die Erfindung betrifft einen Zugmitteltrieb, insbesondere für einen Verbrennungsmotor, mit einem Umschlingungsmittel, einer auf das Umschlingungsmittel einwirkenden Spannvorrichtung, wenigstens einem antreibenden Rad und wenigstens einem angetriebenen Rad, von denen wenigstens eines unrund ausgebildet und/oder exzentrisch gelagert ist.The The invention relates to a traction mechanism, in particular for a Internal combustion engine, with a belt, one on the Strapping means acting tensioning device, at least one driving wheel and at least one driven wheel, of which at least one out of round trained and / or stored eccentrically is.
Hintergrund der Erfindungbackground the invention
Steuerungsantriebe von Verbrennungsmotoren weisen üblicherweise ein Kurbelwellen-Antriebsrad, ein, zwei oder mehrere Nockenwellen-Antriebsräder und ein vorzugsweise als Kette oder Riemen ausgebildetes Umschlingungsmittel auf. Daneben oder alternativ können weitere über Räder angetriebene Zugmitteltriebkomponenten vorhanden sein, die Aggregate wie eine Wasserpumpe, einen Generator, einen Klimakompressor usw. umfassen. Zugmitteltriebe sind aufgrund von Drehmomentschwankungen oder Winkelgeschwindigkeitsänderungen Schwingungsanregungen unterworfen, die in Resonanzbereichen zu hörbaren Geräuschen führen können. Damit sind erhöhte Reibungskräfte verbunden, die die Lebensdauer des Umschlingungstriebs sowie den Wirkungsgrad beeinträchtigen können.control drives of internal combustion engines usually have a crankshaft drive wheel, one, two or more camshaft drive wheels and a preferably designed as a chain or belt entangling on. Besides or alternatively more about Wheels driven Zugmitteltriebkomponenten be present, the aggregates such as a Water pump, a generator, an air compressor, etc. include. Traction drives are due to torque fluctuations or angular velocity changes vibrational excitations subjected, which can lead to audible noise in resonance areas.

Zusammenfassung der ErfindungSummary the invention
Der Erfindung liegt daher das Problem zugrunde, einen Zugmitteltrieb anzugeben, der kostengünstiger herstellbar ist und eine lange Lebensdauer gewährleistet.Of the The invention is therefore based on the problem of a traction drive specify that cost-effective can be produced and ensures a long life.
Zur Lösung dieses Problems ist bei einem Zugmitteltrieb der eingangs genannten Art erfindungsgemäß vorgesehen, dass die Spannvorrichtung als Rastspanner mit einem am Motor befestigten Teil und einem demgegenüber bewegbaren Teil ausgebildet ist, die miteinander verrastet sind, wobei das bewegbare Teil bei nachlassender Spannung des Umschlingungsmittels unter dem Einfluss eines Federelements zum Umschlingungsmittel hin bewegt wird und eine Bewegung in umgekehrter Richtung gesperrt ist.to solution This problem is in a traction drive of the aforementioned Art provided according to the invention, that the tensioning device as a restraint with a part attached to the engine and one in contrast movable part is formed, which are locked together, wherein the movable part with decreasing tension of the belt under the influence of a spring element towards the belt is moved and a movement is locked in the opposite direction.
Der Erfindung liegt die Erkenntnis zugrunde, dass anstelle eines hydraulischen Spannsystems ein einfach aufgebauter und kostengünstiger Rastspanner verwendet werden kann, der in den Zugmitteltrieb integriert ist. Der erfindungsgemäße Zugmitteltrieb umfasst wenigstens ein unrund ausgebildetes und/oder exzentrisch gelagertes Rad, daneben wird ein Rastspanner verwendet, um während der gesamten Lebensdauer des Zugmitteltriebs eine näherungsweise konstante Spannung des Umschlingungsmittels sicherzustellen. Das Umschlingungsmittel ist vorzugsweise als Steuerkette oder Steuerriemen ausgebildet.Of the Invention is based on the finding that instead of a hydraulic Clamping system used a simple and inexpensive Rastspanner can be, which is integrated in the traction mechanism. The traction mechanism according to the invention comprises at least one out of round and / or eccentrically mounted Wheel, next to it, a ratchet tensioner is used to during the overall life of the traction drive an approximately constant voltage of the belt. The belt is preferably designed as a timing chain or timing belt.
Diese Umschlingungsmittel neigen dazu, sich mit fortschreitender Nutzung zu verlängern, wodurch eine Reihe von Problemen entsteht, unter anderem ist bei einem verlängerten Umschlingungsmittel die sichere Führung auf den Rädern oder Riemenscheiben nicht mehr gewährleistet. Zudem nimmt die Lebensdauer des Umschlingungsmittels ab, wenn es nicht mit der vorgesehenen Spannung betrieben wird. Während des Betriebs liegt das bewegbare Teil des Rastspanners, an dem vorzugsweise ein Rad als Spannrolle angeordnet ist, an dem Umschlingungsmittel an, so dass ein Kräftegleichgewicht zwischen der Kraft des Federelements, das das bewegbare Teil gegen das Umschlingungsmittel drückt, und der Reaktionskraft an dem Umschlingungsmittel herrscht. Wenn die Spannung in dem Umschlingungsmittel nachlässt, ist die Kraft des Federelements größer als die entgegengesetzte, vom Umschlingungsmittel auf das bewegbare Teil ausgeübte Kraft, so dass das bewegbare Teil zum Umschlingungsmittel hin bewegt wird. Dadurch wird das Rad, das mit dem bewegbaren Teil verbunden ist, sowie ein gegebenenfalls mit dem Rad gekoppeltes Aggregat in den Zugmitteltrieb gedrückt. Grundsätzlich spielt es keine Rolle, ob der Rastspanner und das damit verbundene Rad außerhalb oder innerhalb des Umschlingungsmittel angeordnet sind, in den meisten Fällen wird es jedoch bevorzugt, dass der Rastspanner das Rad von außen in den Zugmitteltrieb drückt. Der Rastspanner ist so ausgebildet, dass er nur in eine Richtung wirkt, dementsprechend kann das bewegbare Teil von dem feststehenden Teil weg zum Umschlingungsmittel hin bewegt werden, eine Bewegung des Rastspanners in umgekehrter Richtung, das heißt in Richtung auf das feststehende Teil, ist jedoch gesperrt. Dieser Aufbau führt dazu, dass das bewegliche Teil des Rastspanners mit fortschreitender Verlängerung des Umschlingungsmittels zum Umschlingungsmittel hin bewegt wird.These wrappers tend to elongate as usage progresses, creating a number of problems, including the ability to safely guide the wheels or pulleys on an extended wrap. In addition, the life of the belt decreases if it is not operated with the intended voltage. During operation, the movable part of the latching clamp, on which preferably a wheel is arranged as a tensioning roller, abuts on the belting means, so that an equilibrium of forces between the force of the spring element which presses the movable part against the belting means and the reaction force on the belting means prevails. When the tension in the belt means decreases, the force of the spring element is greater than the opposite force exerted by the belt on the movable part, so that the movable part is moved towards the belt. As a result, the wheel, which is connected to the movable part, as well as an optionally coupled to the wheel unit pressed into the traction drive. Basically, it does not matter if the ratchet and the associated wheel are located outside or inside the belt, but in most cases it is preferred that the ratchet pushes the wheel from the outside into the belt drive. The ratchet is designed so that it acts only in one direction, accordingly, the movable part can be moved away from the fixed part to the belt, a movement of the locking device in the reverse direction, that is towards the fixed part, but is locked , This structure causes the moving part of the rastpan ners with progressive extension of the belt is moved towards the belt.
In weiterer Ausgestaltung der Erfindung kann es vorgesehen sein, dass das mit dem Rastspanner verbundene Rad an einer dreh- oder schwenkbar gelagerten Halterungsvorrichtung angeordnet und mit dieser bewegbar ist. Ein derartiger Aufbau hat den Vorteil, dass die Befestigungs- und Lagerpunkte entsprechend den jeweiligen Einbauverhältnissen gewählt werden können. Es ist zweckmäßig, dass die Halterungsvorrichtung einen ersten Lagerpunkt, über den sie dreh- oder schwenkbar am Motor gelagert ist und einen zweiten Lagerpunkt, über den sie mit dem Rastspanner verbunden ist, aufweist. Es ist auch denkbar, dass die Halterungsvorrichtung nicht direkt am Motor oder am Motorblock, sondern an einem damit verbundenen Fahrzeugbauteil, beispielsweise einem Aggregat oder an der Fahrzeugkarosserie gelagert ist, die Anbringung am Motorblock wird jedoch bevorzugt. Bei einer Halterungsvorrichtung, die zwei Lagerpunkte aufweist, können diese näherungsweise beiderseits des Rades einander gegenüberliegend angeordnet sein.In Another embodiment of the invention may be provided that the wheel connected to the ratchet tensioner can be turned or swiveled mounted holding device arranged and movable with this is. Such a structure has the advantage that the fastening and bearing points according to the respective installation conditions chosen can be. It is appropriate that the mounting device has a first bearing point over which it is rotatably or pivotally mounted on the engine and a second Bearing point, over it is connected to the latching tensioner has. It is also conceivable that the mounting device is not directly on the engine or on the engine block, but on an associated vehicle component, for example, an aggregate or stored on the vehicle body However, the attachment to the engine block is preferred. At a Retaining device, which has two bearing points, this can approximately be arranged opposite each other on both sides of the wheel.
Eine besonders zuverlässige Funktion des erfindungsgemäßen Zugmitteltriebs kann erzielt werden, wenn das bewegbare Teil des Rastspanners Rasten umfasst, in die ein federbelastetes Rastelement des an dem Motor befestigten Teils eingreift. Wenn die Spannung in dem Zugmitteltrieb nachlässt, wird das Rasten aufweisende bewegbare Teil des Rastspanners zum Umschlingungsmittel hin verschoben, so dass das federbelastete Rastelement des feststehenden Teils in benachbarte oder andere Rasten eingreift. Mit besonderem Vorteil weist das an dem Motor befestigte Teil eine Sperrvorrichtung auf, die eine Bewegung in die entgegengesetzte Richtung blockiert. Diese Sperrvorrichtung hat eine ähnliche Funktion wie eine Sperrklinke, da sie eine Bewegung des beweglichen Teils von dem feststehenden Teil weg ermöglicht und eine Bewegung in umgekehrter Richtung sperrt.A particularly reliable Function of the traction mechanism according to the invention can be achieved when the movable part of the latching device snaps includes, in which a spring-loaded locking element of the motor engaged part engages. When the tension in the traction drive wears off, will the latching having movable part of the locking device to the belt means shifted so that the spring-loaded locking element of the fixed Partially engaged in adjacent or other notches. With special Advantage, the attached to the motor part has a locking device on, which blocks a movement in the opposite direction. This locking device has a similar function like a pawl, as it moves the moving part away from the fixed part and allows movement in reverse direction locks.
Das Umschlingungsmittel des erfindungsgemäßen Zugmitteltriebs kann ein eine hohe Elastizität aufweisender Elastriemen sein, alternativ kann jedoch auch ein herkömmlicher Riemen eingesetzt werden, der kostengünstiger ist.The Belting means of the traction mechanism according to the invention can be a high elasticity exhibiting Elastriemen be, alternatively, however, a conventional Belt can be used, which is cheaper.
