Description
Die Erfindung betrifft einen Riemenspanner nach dem Oberbegriff des Anspruchs 1, einen Riementrieb nach Anspruch 4 und eine Brennkraftmaschine nach Anspruch 5.The invention relates to a belt tensioner according to the preamble of claim 1, a belt drive according to claim 4 and an internal combustion engine according to claim 5.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, einen Bauraumbedarf einer Brennkraftmaschine zu reduzieren. Diese Aufgabe wird durch einen erfindungsgemäßen Riemenspanner entsprechend dem Anspruch 1, einen Riementrieb entsprechend dem Anspruch 4 und eine Brennkraftmaschine entsprechend dem Anspruch 5 gelöst. Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is in particular the object of reducing a space requirement of an internal combustion engine. This object is achieved by a belt tensioner according to the invention according to claim 1, a belt drive according to claim 4 and an internal combustion engine according to claim 5. Further developments of the invention will become apparent from the dependent claims.
Die Erfindung geht aus von einem Riemenspanner für einen Riementrieb einer Brennkraftmaschine eines Kraftfahrzeugs, mit zwei Spannscheiben, die dazu vorgesehen sind, einen Riemen zu spannen, und mit einem Federelement, das zwei wenigstens in Teilabschnitten gebogene und jeweils eine Spannscheibe aufnehmende Spannarme aufweist, die dazu vorgesehen sind, die Spannscheiben gegen zwei gegenüberliegende Außenseiten des Riemens zu drücken.The invention relates to a belt tensioner for a belt drive of an internal combustion engine of a motor vehicle, with two tensioning pulleys, which are intended to tension a belt, and with a spring element which has two at least partially bent portions and each receiving a tensioning pulley clamping arms, the thereto are provided to press the clamping disks against two opposite outer sides of the belt.
Es wird vorgeschlagen, dass das Federelement als eine windungsfreie Spannspange ausgebildet ist. Dadurch kann ein Federelement, das zur Federung und gleichzeitig zur Befestigung der Spannscheiben genutzt wird, besonders kompakt ausgebildet werden, wodurch ein benötigter Bauraum des Riemenspanners optimiert werden kann. Der Riemenspanner kann besonders kompakt ausgeführt werden, wodurch ein benötigter Bauraum eines Riementriebs reduziert werden kann. Dadurch kann ein Bauraumbedarf einer Brennkraftmaschine reduziert werden und insbesondere eine Quereinbaufähigkeit der Brennkraftmaschine verbessert werden. Außerdem kann der Riemenspanner besonders vorteilhaft angeordnet werden, so dass Lagerbelastungen und Reibung gering gehalten werden können.It is proposed that the spring element is designed as a winding-free clamping clasp. This allows a spring element, which is used for suspension and at the same time for fixing the clamping disks, are made particularly compact, whereby a required space of the belt tensioner can be optimized. The belt tensioner can be made very compact, whereby a required space of a belt drive can be reduced. As a result, a space requirement of an internal combustion engine can be reduced, and in particular a transverse installation capability of the internal combustion engine can be improved. In addition, the belt tensioner can be arranged particularly advantageous, so that bearing loads and friction can be kept low.
Um Montagekosten gering zu halten, wird weiter vorgeschlagen, dass die zwei Spannarme separat zueinander ausgebildet sind, wodurch eine Montage vereinfacht werden kann.To keep assembly costs low, it is further proposed that the two clamping arms are formed separately from each other, whereby a mounting can be simplified.
Für eine besonders kompakte Ausführung ist es insbesondere vorteilhaft, wenn das Federelement zur Aufnahme eines Dämpfers zumindest teilweise hohl ausgebildet ist, wodurch der Dämpfer besonders platzsparend integriert werden kann.For a particularly compact design, it is particularly advantageous if the spring element for receiving a damper is at least partially hollow, whereby the damper can be integrated in a particularly space-saving manner.
Weiter wird ein Riementrieb für eine Brennkraftmaschine eines Kraftfahrzeugs, mit einem erfindungsgemäßen Riemenspanner vorgeschlagen, wodurch ein besonders kompakter Riementrieb bereitgestellt werden kann, der zur antriebstechnischen Verbindung eines Startergenerators, der sowohl als Generator als auch als Motor betrieben wird, mit einer Brennkraftmaschine vorteilhaft eingesetzt werden kann.Further, a belt drive for an internal combustion engine of a motor vehicle, proposed with a belt tensioner according to the invention, whereby a particularly compact belt drive can be provided, which can be used advantageously for driving connection of a starter generator, which is operated both as a generator and as a motor with an internal combustion engine ,
Außerdem wird eine Brennkraftmaschine für ein Kraftfahrzeug, mit einem Startergenerator und einem erfindungsgemäßen Riementrieb, der antriebstechnisch an den Startergenerator angebunden ist, vorgeschlagen, wodurch eine besonders kompakte Brennkraftmaschine mit einem riemengetriebenen Startergenerator bereitgestellt werden kann.In addition, an internal combustion engine for a motor vehicle, with a starter generator and a belt drive according to the invention, which is drivingly connected to the starter generator, proposed, whereby a particularly compact internal combustion engine can be provided with a belt-driven starter generator.
