Mit der erfindungsgemäßen Ausgestaltung wird erreicht, dass der Pleuellagerdeckel vollständig unter eine Vorspannung gesetzt ist. Damit wird die Möglichkeit eröffnet, den Pleuel selbst aus einem leichten Werkstoff von ggf. verringerter Festigkeit herzustellen, weil das Spannelement alle auf den Pleuel wirkenden Zugkräfte aufnimmt und somit die Massenkraftbelastung des Pleuels selbst erheblich reduziert wird. Durch die erfindungsgemäße Ausgestaltung des Pleuels wird eine Verringerung seines Gewichts bei gleichzeitig hoher Belastbarkeit erreicht. Der erfindungsgemäße Pleuel ist zugleich sehr einfach aufgebaut und damit auch in der Serienfertigung wirtschaftlich herstellbar.With the embodiment of the invention is achieved that the connecting rod bearing cover completely under a bias is set. This will be the opportunity opened, the connecting rod itself from a lightweight material of possibly reduced Strength, because the clamping element all on the connecting rod acting tensile forces absorbs and thus significantly reduces the mass load on the connecting rod itself becomes. Due to the inventive design The connecting rod will reduce its weight at the same time high load capacity achieved. The connecting rod according to the invention is also very easy to set up and therefore economical in series production produced.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.advantageous Further developments emerge from the subclaims.
Das Spannelement kann am großen Pleuelauge in seinem dem Pleuelschaft zugewandten Bereich befestigt sein. Es kann aber auch durch eine im Pleuelschaft vorgesehene Durchlassöffnung hindurch geführt und am Pleuellagerdeckel befestigt sein. Beide Ausgestaltungen haben die erfindungsgemäße Wirkung, die Massenkraftbelastung des Pleuels durch Aufnahme der Zugkräfte zu reduzieren.The Clamping element can be large Pleuelauge attached in his the connecting rod shank facing area be. But it can also pass through a provided in the connecting rod passage opening guided and be attached to the connecting rod bearing cap. Both configurations have the effect according to the invention, reduce the mass load of the connecting rod by absorbing the tensile forces.
Die Befestigung des Spannelements am großen Pleuelauge kann auf eine beliebige Art und Weise je nach den Anforderungen des Einzelfalls erfolgen. Eine besonders praktikable Lösung besteht darin, mindestens ein Befestigungsmittel vorzusehen. Das Spannelement kann bspw. durch mindestens eine im großen Pleuelauge vorgesehene Bohrung geführt und mittels des mindestens einen Befestigungsmittels gehalten sein. Dies ist eine besonders einfache konstruktive Ausgestaltung, die auch in der Serienfertigung wirtschaftlich eingesetzt werden kann. Geeignete Befestigungsmittel sind bspw. Muttern oder Schrauben.The Attachment of the clamping element on the large connecting rod eye can on a Any way according to the requirements of the case respectively. A particularly practical solution is, at least to provide a fastener. The clamping element can, for example. By at least one in the big one Pleuelauge provided bore out and by means of at least be held a fastener. This is a very simple one constructive design, which is also economical in mass production can be used. Suitable fasteners are, for example. Nuts or screws.
Das mindestens eine Befestigungsmittel kann seitlich am großen Pleuelauge oder stirnseitig am Pleuellagerdeckel vorgesehen sein. Beide Ausgestaltungen haben den Vorteil, dass das mindestens eine Befestigungsmittel in montiertem Zustand, insbesondere bei eingebauter Kurbelwelle, zugänglich ist. Es ist auch denkbar, das mindestens eine Befestigungsmittel in dem dem Pleuelschaft benachbarten Bereich des großen Pleuelauges anzuordnen. Eine solche Anordnung hat ebenfalls die erfin dungsgemäße Wirkung, die Massenkraftbelastung des Pleuels durch Aufnahme der Zugkräfte zu reduzieren und ist daher ebenfalls praktikabel, aber weniger komfortabel für die Montage und Demontage des Pleuels im Motor.The at least one fastening means can laterally on the large connecting rod eye or be provided on the front end on the connecting rod bearing cap. Both embodiments have the advantage that at least one fastener in assembled state, especially when installed crankshaft, is accessible. It is also conceivable that at least one fastening means in the to arrange the connecting rod shank adjacent area of the large connecting rod eye. A Such arrangement also has the inven tion proper effect, the mass load of the connecting rod by absorbing the tensile forces and is therefore also practical, but less comfortable for assembly and disassembly of the connecting rod in the engine.
Es ist denkbar, das Spannelement zumindest teilweise in einer im großen Pleuelauge angeordneten Nut zu führen und somit besonders zuverlässig ortsfest auf der Außenfläche des großen Pleuelauges zu halten.It is conceivable, the clamping element at least partially in a large connecting rod to lead arranged groove and thus very reliable stationary on the outer surface of the huge To hold the connecting rod eye.
