Abstract
Description
Die Erfindung betrifft einen Riementrieb eines Verbrennungsmotors mit einem ersten Trieb in einer ersten Triebebene mit einer mit der Kurbelwelle verbundenen Kurbelwellenscheibe und mit wenigstens einer mit einem Nebenaggregat verbundenen Nebenaggregatscheibe, wobei die Scheiben über einen ersten Riemen miteinander verbunden sind und mit einem zweiten Trieb in einer zweiten Triebebene mit wenigstens einer, mit einem Nebenaggregat verbundenen Nebenaggregatscheibe und einer Antriebsscheibe, wobei die Scheiben über einen zweiten Riemen miteinander verbunden sind und wobei die Riemen beider Triebebenen über eine gemeinsame Spannvorrichtung gespannt sind.The invention relates to a belt drive of an internal combustion engine with a first drive in a first drive plane with a crankshaft pulley connected to the crankshaft and at least one auxiliary pulley connected to an auxiliary unit, wherein the pulleys are connected to each other via a first belt and with a second drive in a second Drive level with at least one associated with an accessory accessory disk and a drive pulley, wherein the discs are connected to each other via a second belt and wherein the belts of both drive levels are stretched over a common tensioning device.
Riementriebe eines Verbrennungsmotors mit einer Triebebene oder mit zwei Triebebenen sind dem Fachmann bekannt. Die Triebebenen dienen zum Antrieb von Aggregaten wie beispielsweise Klimakompressor, Lenkhilfspumpe, Generator, Lüfter. Bei der Anordnung einer Triebebene wird der Riemen über eine Spanneinrichtung zum Erhalt einer gleichmäßigen Riemenspannung gespannt. Hierzu sind starre Spannvorrichtungen oder auf einem Feder-Dämpfer-System basierende Spannvorrichtungen bekannt. Bei Riementrieben mit zwei Triebebenen ist es beispielsweise aus der
Es ist daher die Aufgabe der Erfindung, einen Riementrieb mit zwei Triebebenen für einen Verbrennungsmotor bereitzustellen, bei dem auf aufwendige Spannvorrichtungen verzichtet werden kann, bei dem die Freiheit der Triebanordnung vergrößert ist und bei dem Gewicht eingespart werden kann.It is therefore the object of the invention to provide a belt drive with two drive levels for an internal combustion engine, can be dispensed with in the complex fixtures, in which the freedom of the drive assembly is increased and can be saved in the weight.
Die Aufgabe wird gelöst, indem für den zweiten Trieb die Spannvorrichtung die Antriebsscheibe ist, indem die Spannung beider Triebe über die gemeinsame Spannvorrichtung starr erfolgt und indem die Riemen ELASTIC-Riemen sind.The object is achieved in that for the second drive, the tensioning device is the drive pulley, in that the tension of both drives via the common tensioning device is rigid and in that the belts are ELASTIC belts.
Mit der erfindungsgemäßen Lösung wird der zweite Trieb über die mit dem ersten Trieb gemeinsame Spannvorrichtung angetrieben, so dass die Einbindung einer gesonderten Kurbelwellenscheibe in den zweiten Trieb nicht erforderlich ist, sondern auf diese verzichtet werden kann. Die Freiheit der Gestaltung der Triebanordnung ist hierdurch vergrößert und der Trieb ist bauraumsparend anzuordnen. Zudem erfolgt die gemeinsame Spannung beider Triebe über eine starre Spannvorrichtung, welche konstruktiv einfach und platzsparend ist. Denn durch den Einsatz von ELASTIC-Riemen kann auf eine auf dem Feder-Dämpfer-System basierende Spannvorrichtung verzichtet werden. Die Einstellung der Vorspannung des Triebes erfolgt über die Elastizität und Länge des Riemens und nicht über die Feder der auf dem Feder-Dämpfer-System beruhenden Spannvorrichtung des Standes der Technik. Somit wird durch den erfindungsgemäßen Trieb erreicht, dass auf aufwendige Spanneinrichtungen verzichtet werden kann. Die Freiheit der Triebanordnung ist vergrößert.With the solution according to the invention, the second drive is driven via the tensioning device common to the first drive, so that the integration of a separate crankshaft pulley in the second drive is not required, but can be dispensed with. The freedom of the design of the drive assembly is thereby increased and the drive is to save space. In addition, the common voltage of both drives via a rigid clamping device, which is structurally simple and space-saving. The use of ELASTIC belts eliminates the need for a tensioning device based on the spring-damper system. The adjustment of the bias of the drive is made on the elasticity and length of the belt and not on the spring of the spring-damper system-based tensioning device of the prior art. Thus, it is achieved by the drive according to the invention that can be dispensed with expensive clamping devices. The freedom of the drive arrangement is increased.
Ein ELASTIC-Riemen meint einen elastischen Riemen, welcher aufgrund seiner Konstruktion eine höhere Elastizität als herkömmliche Riemen besitzt. Der ELASTIC-Riemen weist, wie bei Treibriemen üblich, Korde als Festigkeitsträger auf. Der ELASTIC-Riemen zeichnet sich aufgrund spezieller Kord-Eigenschaften durch eine höhere Elastizität aus. Der ELASTIC-Riemen wird mit einer bestimmten Länge gefertigt, aber mit einer größeren Länge auf dem Riementrieb eingesetzt. Bei der Montage auf den Riemenscheiben wird der Riemen also um einen gewissen Prozentsatz gedehnt und dadurch vorgespannt.An ELASTIC belt means an elastic belt which, due to its construction, has a higher elasticity than conventional belts. The ELASTIC belt has cords as a strength carrier, as is the case with drive belts. The ELASTIC belt is characterized by special elastic properties due to its special cord properties. The ELASTIC belt is made with a certain length, but used with a longer length on the belt drive. When mounting on the pulleys, the belt is thus stretched by a certain percentage and thereby biased.
Vorteilhaft ist es, wenn die Spannvorrichtung eine Doppelspannrolle ist. Es ist ein Bauraumvorteil erreicht.It is advantageous if the clamping device is a double-clamping roller. It is achieved a space advantage.
Der Verstellweg der Spannvorrichtung ist linear oder rotatorisch und ist von einem Montageanschlag, in dem die ELASTIC-Riemen zwanglos aufgelegt werden können, durch Verschiebung der Spannvorrichtung in einem Endanschlag zu fixieren. Die ELASTIC-Riemen sind gespannt.The adjustment of the tensioning device is linear or rotary and is to be fixed by an assembly stop in which the ELASTIC belts can be laid casually by moving the clamping device in an end stop. The ELASTIC belts are stretched.
Die Doppelspannrolle kann verschieden ausgeführt sein. In bestimmten Ausführungsformen ist die Doppelspannrolle an der Riemenauflagefläche profiliert oder glatt ausgeführt. In einer anderen Ausführungsform kann eine Spannrolle der Doppelspannrolle profiliert und die andere Spannrolle der Doppelspannrolle glatt ausgeführt sein. Es ist eine Freiheit in der Ausgestaltung der Doppelspannrolle erreicht, wodurch eine Anpassung an die erwünschte Kraftübertragung des Triebes ermöglicht ist.The double-clamping roller can be designed differently. In certain embodiments, the double tension pulley is profiled or smooth on the belt support surface. In another embodiment, a tension roller of the double-tensioning roller profiled and the other tensioning roller of the double-clamping roller be made smooth. It is achieved a freedom in the design of the double-clamping roller, whereby an adaptation to the desired power transmission of the drive is made possible.
Die Spannvorrichtung in Form einer Doppelspannrolle ist je nach Triebausführung außen- oder innenliegend zu betreiben.The clamping device in the form of a double-clamping roller is to be operated outside or inside, depending on the drive design.
Vorteilhaft ist es, wenn die ELASTIC-Riemen beider Triebe die gleiche Elastizität oder eine unterschiedliche Elastizität aufweisen. Hierdurch ist es ermöglicht, in Kombination mit der Bauanordnung der Triebe, dem Verstellweg der Spannvorrichtung die erwünschte Vorspannung im ersten und zweiten Trieb einzustellen.It is advantageous if the ELASTIC belts of both drives have the same elasticity or a different elasticity. This makes it possible, in combination with the construction of the shoots, the adjustment of the clamping device the set desired bias in the first and second drive.
Weitere Merkmale, Vorteile und Einzelheiten der Erfindung werden nun anhand der Zeichnung, die ein schematisches Ausführungsbeispiel darstellt, näher erläutert.Further features, advantages and details of the invention will now be explained in more detail with reference to the drawing, which is a schematic embodiment.
