Abstract
Hubkolben-Brennkraftmaschine mit einer Kurbelwelle, mit der ein Nockenwellenantrieb für eine Ventilsteuerung über ein Zugmittel antreibbar ist, der zwischen einem Abtriebsende der Kurbelwelle und einem diesem Abtriebsende benachbarten Hauptlager der Kurbelwelle angeordnet ist, wobei das Zugmittel ein Zahnriemen ist und dass zwischen dem Abtriebsende und dem Hauptlager eine Riemenscheibe angeordnet ist. Durch die erfindungsgemäße Anordnung werden die Reibleistung reduziert, die Akustik verbessert, die Kosten gesenkt und das Package verbessert.Reciprocating internal combustion engine with a crankshaft, with which a camshaft drive for valve control via a traction means is driven, which is arranged between a driven end of the crankshaft and a main end of this crankshaft adjacent this output end, the traction means is a toothed belt and that between the output end and the Main bearing a pulley is arranged. The inventive arrangement reduces friction, improves acoustics, reduces costs and improves the package.
Description
Die Erfindung betrifft eine Hubkolben-Brennkraftmaschine mit einer Kurbelwelle mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a reciprocating internal combustion engine with a crankshaft having the features of the preamble of patent claim 1.
Zum technischen Umfeld wird beispielsweise auf die deutsche Offenlegungsschrift
Nachteilig an dieser Ausgestaltung ist die relativ große Baulänge der Hubkolben-Brennkraftmaschine.A disadvantage of this configuration is the relatively large length of the reciprocating internal combustion engine.
Weiter ist auch aus der deutschen Offenlegungsschrift
Nachteilig an dieser bekannten Ausführungsform ist der hohe bauliche Aufwand.A disadvantage of this known embodiment, the high construction costs.
Weiter ist aus der
Nachteilig an dieser Ausgestaltung ist der hohe Reibungsverlust bei der Kraftübertragung über die Kegelzahnräder.A disadvantage of this configuration is the high friction loss during power transmission via the bevel gears.
Grundsätzlich weist ein Nockenwellenantrieb für eine Ventilsteuerung mit einer Kette im Vergleich zu einer Ventilsteuerung mit Zahnriemen folgende Nachteile auf:
- – Schlechte Reibleistung
- – Schlechte Akustik
- – Hohe Kosten
- – Ungünstiges Package
- - Bad friction
- - bad acoustics
- - High costs
- - Unfavorable package
Aufgabe der vorliegenden Erfindung ist es, einen Nockenwellenantrieb für eine Ventilsteuerung für eine Hubkolben-Brennkraftmaschine mit einer Kurbelwelle darzustellen, der die oben genannten Nachteile nicht aufweist.Object of the present invention is to present a camshaft drive for a valve control for a reciprocating internal combustion engine with a crankshaft, which does not have the disadvantages mentioned above.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is solved by the features in the characterizing part of patent claim 1.
Die erfindungsgemäße Ausgestaltung der Hubkolben-Brennkraftmaschine weist in vorteilhafter Weise eine reduzierte Reibleistung, eine deutlich verbesserte Akustik, geringere Herstellkosten und ein besseres Package auf.The inventive design of the reciprocating internal combustion engine advantageously has a reduced friction, a significantly improved acoustics, lower production costs and a better package.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen ausgeführt.Advantageous developments of the invention are set forth in the subclaims.
So ist in einer bevorzugten Ausführungsform gemäß Patentanspruch 2 die Riemenscheibe mit der Kurbelwelle einstückig und vorzugsweise materialeinheitlich ausgeführt.Thus, in a preferred embodiment according to claim 2, the pulley with the crankshaft in one piece and preferably made of the same material.
In oben genannter Ausgestaltung können die Kurbelwelle und die Riemenscheibe gemäß Patentanspruch 3 spanend, beispielsweise durch Fräsen oder spanlos, beispielsweise durch Umformen oder Walzen hergestellt werden.In the above-mentioned embodiment, the crankshaft and the pulley can be produced according to claim 3 by cutting, for example by milling or without cutting, for example by forming or rolling.
Im Folgenden ist die Erfindung anhand eines Ausführungsbeispieles in einer einzigen Figur näher erläutert.In the following the invention with reference to an embodiment in a single figure is explained in more detail.
Mit Hilfe der erfindungsgemäß an die Kurbelwelle
Die erfindungsgemäße Ausgestaltung der Hubkolben-Brennkraftmaschine weist in vorteilhafter Weise eine reduzierte Reibleistung, eine deutlich verbesserte Akustik, geringere Herstellkosten und ein besseres Package gegenüber dem bekannten Stand der Technik auf.The inventive design of the reciprocating internal combustion engine advantageously has a reduced friction, a significantly improved acoustics, lower production costs and a better package over the known prior art.
Bisher waren Zahnriemen noch mit Wechselintervallen versehen, sprich nicht lebensdauerfest. Die Kombination „Zahnriemen hinten” und „nicht lebensdauerfester Zahnriemen” wird es nicht geben, da ein Zahnriemenwechsel während der Lebensdauer einer Hubkolben-Brennkraftmaschine untragbar wäre. Mittlerweile wird von bekannten Zahnriemen-Herstellern an lebensdauerfähigen Zahnriemen in Öl gearbeitet, die teilweise auch schon in der Serie umgesetzt sind. Das ermöglicht erstmals den erfindungsgemäßen Aufbau einer Hubkolben-Brennkraftmaschine mit einem Zahnriemen hinten (abtriebsseitig), da ein Zahnriemenwechsel nicht mehr nötig ist.To date, timing belts were still provided with change intervals, ie not life-long. The combination "toothed belt rear" and "not life-long belt" will not exist because a timing belt replacement during the life of a reciprocating internal combustion engine would be intolerable. In the meantime, well-known timing belt manufacturers are working on life-long belts in oil, some of which have already been implemented in series production. This allows for the first time the construction of a reciprocating internal combustion engine according to the invention with a toothed belt rear (output side), since a timing belt replacement is no longer necessary.
