Abstract
Description
Die Erfindung betrifft eine Kühlkanalabdeckung für einen Kolben eines Verbrennungsmotors mit einem im Kolbenkopf auf Höhe des Kolbenringbandes ringförmig umlaufenden, in Richtung Kolbenschaft hin offenem Kühlkanal, der durch eine zweigeteilte, sich an im Kühlkanal angeordnete radial innere und äußere Auflager abstützende, kreisförmige Tellerfeder abgedeckt ist, wobei der Kolbenschaft mit am Kolbenkopf angehängten Kolbennaben verbunden ist.The The invention relates to a cooling channel cover for one Piston of an internal combustion engine with one in the piston head at the level of the piston ring band annular circumferential, in the direction of the piston skirt open cooling channel, by a two-part, arranged in the cooling channel radially inner and outer supports supporting, circular Disc spring is covered, the piston shaft with the piston head attached Piston hubs is connected.

Nachteilig bei den vorgenannten zweigeteilten Ausführungsformen ist, dass einerseits der kreisförmige Abdeckring bzw. Tellerfeder trotz seiner vorgespannten Einbaulage im Motorbetrieb wegen der Verformung des Kolbens infolge des einwirkenden Druckes der Verbrennungsgase, aber auch wegen der Hin- und Herbewegung des Kolbens und der Massenkraftbelastung des Kühlöls, eine Relativbewegung gegenüber seiner Kolbenauflage ausführt. Anderseits liegen zweigeteilte kreisförmige Tellerfedern umfangsseitig in Einbaulage nicht gleichmäßig mit ihren Stirnflächen an ihrem kreisförmigen Auflager des Kolbens an. Die Tellerfeder bewirkt somit umfangseitig unterschiedliche axiale und radiale Flächenpressungen und Vertormungen an Ihrem Auflager, so dass unter dem Einfluss der vorgenannten Verformungen und Relativbewegung ein erhöhter Verschleiß entsteht, bis letztlich beide Teile der Tellerfeder aus ihrem Auflager herausfallen und den Kolben beschädigen können.adversely in the aforementioned two-part embodiments is that on the one hand the circular one Cover ring or disc spring despite its preloaded installation position in engine operation due to the deformation of the piston due to the applied pressure the combustion gases, but also because of the float's movement Piston and the mass load of the cooling oil, a relative movement relative to his Performs piston support. On the other hand, lie divided into two parts Disc springs circumferentially in installation position not evenly with their faces at her circular Support of the piston. The diaphragm spring thus causes peripherally different axial and radial surface pressures and deformations at your support, so that under the influence of the aforementioned deformations and relative movement an increased wear arises until finally both parts of the disc spring fall out of their support and damage the piston can.
Hiervon ausgehend liegt der Erfindung das Problem zugrunde, die erwähnten Nachteile des Standes der Technik zu vermeiden.Of these, Based on the problem underlying the invention, the disadvantages mentioned of the prior art.
Gelöst wird die Aufgabe durch die Merkmale des Hauptanspruches.Is solved the task by the features of the main claim.
Vorteilhaft wird dadurch eine zweigeteilte Tellerfeder geschaffen, deren umfangsseitig erzeugte Flächenpressung annährend gleich groß ist, wodurch eine Verringerung des Tellerfederverschleißes erzielt wird.Advantageous This creates a two-part plate spring whose circumference generated surface pressure approximately is the same size whereby a reduction of the diaphragm spring wear achieved becomes.
