Abstract
Es wird ein Kolben (1) für einen Verbrennungsmotor mit einem im Wesentlichen zylinderförmigen Grundkörper (4) aus geschmiedetem Aluminium und einem im radial äußeren Randbereich des Kolbenbodens (5) angeordneten Ringelement (6) vorgeschlagen, das mit dem Grundkörper (4) einen ringförmigen Kühlkanal (22) bildet. Das Ringelement (6) besteht aus gegossenem Aluminium und weist einen aus NiResist bestehenden Ringträger (11) für einen Verdichtungsring auf.A piston (1) for an internal combustion engine with a substantially cylindrical base body (4) made of forged aluminum and a ring element (6) arranged in the radially outer edge region of the piston head (5) is proposed, which forms an annular cooling channel with the base body (4) (22) forms. The ring element (6) consists of cast aluminum and has a NiResist ring carrier (11) for a compression ring.
Description
Die Erfindung betrifft einen Kolben für einen Verbrennungsmotor nach dem Oberbegriff des Patentanspruches.The The invention relates to a piston for an internal combustion engine the preamble of claim.
Ein Kolben für einen Verbrennungsmotor mit einem Grundkörper aus Aluminium und einem im radial äußeren Randbereich des Kolbenbodens angeordneten Ringelement, das mit dem Grundkörper einen ringförmigen Kühlkanal bildet, ist aus dem US-Patent 2,772,933 bekannt. Das Ringelement besteht aus einer Eisenlegierung, was den Nachteil mit sich bringt, dass das Ringelement einen erheblichen Beitrag zu Vergrößerung des Kolbengewichtes leistet.One Piston for an internal combustion engine with a base made of aluminum and a in the radially outer edge region the piston crown arranged ring element, with the main body a annular cooling channel is from the US patent 2,772,933 known. The ring element consists of an iron alloy, which has the disadvantage that the ring element makes a significant contribution to enlarge the Piston weight makes.
Diesen Nachteil zu vermeiden ist Aufgabe der Erfindung. Gelöst wird die Aufgabe mit den im Kennzeichen der Hauptanspruches stehenden Merkmalen. Eine zweckmäßige Ausgestaltung der Erfindung ist Gegenstand des Unteranspruches.this Disadvantage to avoid is the object of the invention. Is solved the task with the standing in the characterizing part of the main claim Features. An expedient embodiment The invention is the subject of the dependent claim.
Das erfindungsgemäß aus Aluminium bestehende Ringelement mit einem aus NiResist bestehenden Ringträger für einen Verdichtungsring vereint den Vorteil, das Kolbengewicht zu verringern, mit dem Vorteil, eine verschleißfeste Lagerung für den Verdichtungsring zu bieten und damit die Belastbarkeit und die Lebensdauer des Kolbens zu vergrößern.The according to the invention of aluminum existing ring element with a consisting of NiResist ring carrier for a Compression ring combines the advantage of reducing the weight of the piston with the advantage of a wear-resistant Storage for to provide the compression ring and thus the capacity and the To increase the life of the piston.
