Abstract

The equipment (1) has through treads for a piston rod. The equipment is arranged firmly above a crankshaft (2) at a crank case wall (4). The equipment extends over an entire length of a crankcase (8). The equipment is manufactured from aluminum or plastics. The equipment extends from a junction of a crank shaft piston rod to another junction. Oil, which is squirted from spray nozzles below cylinders under a piston of an internal combustion engine, flows to the wall of the cylinders.

Description

Die Erfindung betrifft eine Leiteinrichtung zum Abschirmen einer Kurbelwelle einer Brennkraftmaschine von Öl mit den Merkmalen des Oberbegriffs von Anspruch 1.The The invention relates to a guide for shielding a crankshaft an internal combustion engine of oil with the features of the preamble of claim 1.

Die Zylinder von Brennkraftmaschinen sind ölgekühlt, indem über eine Spritzdüse Öl auf die Kolbenunterseite gespritzt wird, von wo es entlang der Zylinder- und Kurbelgehäuse-Wandungen in den Schmiermittelsumpf abfließt. Kritisch ist es, wenn abfließendes Öl auf die rotierende Kurbelwelle gelangt, da hierdurch das Öl verschäumen und sich erwärmen kann. Dies verursacht einen Leistungsverlust der Brennkraftmaschine.The Cylinders of internal combustion engines are oil cooled by applying oil through a spray nozzle Piston bottom is sprayed, from where it along the cylinder and crankcase walls in the lubricant sump flows. It is critical, if draining oil on the rotating crankshaft passes, as this foaming the oil and can warm up. This causes a power loss of the internal combustion engine.

Aus der JP-A 0517 2058 ist zum Vermeiden von Ölpanschen ein Abschirmblech bekannt, welches Verbindungsstellen der Kurbelwelle mit den Pleueln umgibt. Das Abschirmblech ist drehfest mit der Kurbelwelle und rotiert mit dieser, so dass Leistungsverluste an der Kurbelwelle resultieren. Das Abschirmblech ist zudem für eine Brennkraftmaschine mit Kolbenkühlung nur eingeschränkt hilfreich, da zurücklaufendes Öl trotz des Abschirmblechs auf drehende Teile gelangen kann.Out JP-A 0517 2058 is a shielding plate for avoiding oil spills known, which joints of the crankshaft with the connecting rods surrounds. The shield is rotatable with the crankshaft and rotated with this, so that power losses at the crankshaft result. The shielding is also for an internal combustion engine with piston cooling only limited helpful, there returning oil despite of the shielding plate can reach rotating parts.

Aufgabe der Erfindung ist es, die Kurbelwelle einer Brennkraftmaschine zuverlässig von ablaufendem Öl abzuschirmen.task The invention is the crankshaft of an internal combustion engine reliably from draining oil shield.

Die Lösung erfolgt mit einer Leiteinrichtung zum Abschirmen einer Kurbelwelle einer Brennkraftmaschine von Öl mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Unteransprüchen dargestellt.The solution takes place with a guide for shielding a crankshaft an internal combustion engine of oil with the features of claim 1. Advantageous embodiments of the invention are in the dependent dependent claims shown.

Mit der erfindungsgemäßen Leiteinrichtung ergibt sich vorteilhaft beruhigt ablaufendes, nicht verschäumendes Öl, weil Panschen der Kurbelwelle mit dem rücklaufenden Öl unterbleibt. Erfindungsgemäß ergibt sich folglich der weitere Vorteil eines gegenüber dem Stand der Technik verkleinerten Öl-Beruhigungsraums unterhalb der Kurbelwelle. Die erfindungsgemäße Leiteinrichtung ist konstruktiv einfach, kostengünstig herstell- und auch nachträglich einbaubar.According to the invention a guide is provided for shielding a crankshaft an internal combustion engine of oil from an oil supply device, which are arranged under pistons of cylinders of the internal combustion engine is. The guide is fixed above the crankshaft at least a crankcase wall arranged and passes running oil past the crankshaft to the bottom plate of the crankcase. With the guide device according to the invention results in advantageous calmed, non-foaming oil, because Pan of the crankshaft with the returning oil is omitted. According to the invention Consequently, the further advantage of a reduced compared to the prior art oil-calming space below the crankshaft. The guide device according to the invention is constructive simple, inexpensive manufactured and also afterwards mountable.

Die Leiteinrichtung erstreckt sich über die gesamte Länge des Kurbelgehäuses. Alternativ erstreckt sich die Leiteinrichtung von einer Verbindungsstelle Kurbelwelle-Pleuel zur Nächsten.The Guide extends over the entire length of the crankcase. Alternatively, the guide extends from a junction Crankshaft connecting rod to the next.

Gemäß einer Ausgestaltung der Erfindung ist die Brennkraftmaschine als V-Motor ausgebildet und zu jeder Seite des V-Motors mindestens eine Leiteinrichtung, oder alternativ nur eine Leiteinrichtung, vorgesehen. According to one Embodiment of the invention is the internal combustion engine as a V-engine formed and at least one guide device to each side of the V-motor, or alternatively only a guide, provided.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist die Leiteinrichtung mit Durchtritten für die Pleuel versehen.According to one Another preferred embodiment of the invention is the guide with passages for provided the connecting rods.

In der Praxis besteht die Leiteinrichtung aus Aluminium oder Kunststoff.In In practice, the guide consists of aluminum or plastic.

Die Erfindung wird im Folgenden anhand eines bevorzugten Ausführungsbeispiels dargestellt.The Invention will be described below with reference to a preferred embodiment shown.

Es zeigen:It demonstrate:
