Abstract
Description
Gebiet der ErfindungTerritory of invention
Die Erfindung betrifft ein Spannelement für einen Zugmitteltrieb wie einen Riemen oder eine Kette, insbesondere für einen Riementrieb eines Kraftfahrzeugs, umfassend ein erstes und ein zweites Elementteil, die axial gegeneinander bewegbar sind, sowie ein in dem gehäuseartigen zweiten Elementteil angeordnetes Federelement, wobei die Elementteile gegen die Rückstellkraft des Federelements in eine maximale Einfahrstellung und durch Entlasten des Federelements in eine maximale Ausfahrstellung relativ zueinander bewegbar sind.The The invention relates to a clamping element for a traction mechanism such as a belt or a chain, in particular for a belt drive of a motor vehicle, comprising a first and a second element part axially against each other are movable, and arranged in the box-like second element part Spring element, wherein the element parts against the restoring force of the spring element in a maximum retracting position and by relieving the spring element are movable relative to each other in a maximum extended position.
Hintergrund der Erfindungbackground the invention
Ein
solches Spannelement ist beispielsweise in Form eines hydraulischen
Spannelements aus
Das Spannelement wird mit einem Ende am gehäuseartigen Elementteil an einem Drittgegenstand wie beispielsweise dem Motorblock, und mit dem anderen Ende wie beschrieben beispielsweise an dem Spannhebel befestigt. Über die Spannrolle des Spannhebels ist das zu spannende Zugmittel, z. B. ein Riemen, geführt. Der Riemen drückt den Kolben gegen die Rückstellkraft der Feder und komprimiert diese. Über diese Feder wird der Riemen folglich gespannt.The Clamping element is connected to one end of the housing-like element part on a Third object such as the engine block, and with the other End as described, for example, attached to the clamping lever. About the Tensioning roller of the clamping lever is to exciting tension means, z. B. a belt, guided. The belt pushes the piston against the restoring force the spring and compresses it. About this spring is the belt therefore excited.
Der gespannte Riemen verhindert, dass das Federelement die beiden Elementteile in die maximale Ausfahrstellung bewegt. Reißt jedoch der Riemen, so wird das Federelement schlagartig entlastet und bewegt die Elementteile schlagartig auseinander. Bedingt durch den sehr geringen Bauraum, der für die Verlagerung z. B. des Spannhebels nebst Spannrolle zur Verfügung steht, kann die Spannrolle oder aber auch der Spannhebel bei dieser „schnalzenden" Expansion mit angrenzenden Bauteilen kollidieren, was zu Beschädigungen dieser oder der Spannrolle oder des Spannhebels führen kann.Of the Tensioned strap prevents the spring element from the two element parts moved to the maximum extension position. However, if the belt breaks, it will the spring element suddenly relieves and moves the element parts abruptly apart. Due to the very small installation space, the for the shift z. B. the clamping lever and tensioner is available, can the tensioner or even the clamping lever in this "clicking" expansion with adjacent Components collide, causing damage to this or the tensioner or the clamping lever lead can.
Zusammenfassung der ErfindungSummary the invention
Der Erfindung liegt damit das Problem zugrunde, ein Spannelement anzugeben, das auch im Falle eines Riemen- oder Kettenrisses eine unerwünschte Bewegung des oder der mit dem Spannelement gekoppelten Spannmittel verhindert.Of the The invention is therefore based on the problem of specifying a clamping element, this also in the case of a belt or chain crack undesirable movement the one or the coupled with the clamping element clamping means prevented.
Zur Lösung dieses Problems ist bei einem erfindungsgemäßen Spannelement vorgesehen, dass ein bedarfsabhängig nutzbares Arretiermittel vorgesehen ist, über das die Ausfahrbewegung der beiden Elementteile vor Erreichen der maximalen Ausfahrstellung begrenzt wird.to solution this problem is provided in a tensioning element according to the invention, that one needs-based usable locking means is provided, via which the extension movement the two element parts before reaching the maximum extension position is limited.
Nach dem Montieren des Spannelements in den Zugmitteltrieb, wenn also der Riemen oder die Kette gelegt und folglich das Spannelement komprimiert ist, sorgt das erfindungsgemäß vorgesehene Arretiermittel dafür, dass bei einem plötzlichen Entlasten des Spannelements wie beispielsweise bei einem Riemen- oder Kettenriss die Ausfahrbewegung begrenzt wird, so dass wirksam verhindert wird, dass das Spannelement seine maximale Ausfahrstellung überhaupt einnehmen kann, und es nicht zu einem ungewünschten Anschlag der Spannrolle oder des Spannhebels infolge dieser bauraummäßig unzulässig großen Ausfahrbewegung kommen kann.To the mounting of the clamping element in the traction drive, if so placed the belt or chain and thus compresses the clamping element is, provides the inventively provided locking for this, that at a sudden Relieving the tensioning element, as in the case of a belt or chain tear the extension movement is limited, making effective prevents the clamping element its maximum extended position at all can take, and it does not lead to an unwanted stop of the tensioner or the clamping lever come as a result of this space in terms of inadmissibly large extension movement can.
Erfindungsgemäß umfasst das Arretiermittel ein an einem Elementteil außenseitig angeordnetes oder mit diesem bewegbares erstes Arretierteil, das zur Bewegungsbegrenzung mit einem am anderen Elementteil außenseitig angeordneten oder mit diesem bewegbaren zweiten Arretierteil zusammenwirkt.According to the invention the locking means a on an element part outside or arranged with this movable first locking part, which is used to limit the movement with one on the other part part arranged on the outside or cooperates with this movable second locking part.
Dabei kann nach einer ersten Erfindungsalternative das erste Arretierteil ein Rasthaken und das zweite Arretierteil ein zur Arretierung vom Rasthaken hintergriffener Vorsprung sein, wobei der Rasthaken bevorzugt an einem im Bereich der Befestigung des ersten Elementteils an einem Drittgegenstand, also dem Lagerauge des Elementteils, zu befestigenden Blechteil vorzugsweise endseitig vorgesehen ist, während der Rastvorsprung mittels eines auf das zweite gehäuseartige Elementteil aufgepresster Rings gebildet ist.there may according to a first invention alternative, the first locking part a locking hook and the second locking part for locking the Latch hook be engaged behind projection, the catch hook preferred at one in the region of the attachment of the first element part to a Third object, ie the bearing eye of the element part, to be fastened sheet metal part is preferably provided at the end, while the locking projection by means one on the second box-like Element part pressed rings is formed.
Eine Erfindungsalternative sieht demgegenüber vor, dass das erste Arretierteil ein in einer Aufnahme am ersten Elementteil eingesteckter Splint ist, der gewinkelt ausgeführt ist und sich längs des Spannelements zum zweiten Elementteil erstreckt, wobei das zweite Arretierteil ein am zweiten Elementteil angeordnetes Führungselement ist, an dem ein Anschlag des Splints zur Bewegungsbegrenzung anschlägt. Der Splint selbst ist mit seinem längs des Spannelements außenseitig geführten Abschnitt in das Führungselement, das seitlich eine Einschnappöffnung aufweist, von der Seite her eingerastet, dort also geführt, kann sich aber nicht versehentlich aus seiner Führung lösen.An alternative to the invention, on the other hand, provides that the first locking part is a split pin inserted in a receptacle on the first element part, which is angled and extends along the tensioning element to the second element part, wherein the second locking part is a guide element arranged on the second element part Stop of the cotter pin for movement limitation strikes. The sap itself is with his along the Clamping element outwardly guided portion in the guide member having a Einschnappöffnung laterally, locked from the side, there guided, but can not be accidentally released from its leadership.
