Abstract
Hubkolben-Brennkraftmaschine mit einer Kurbelwelle und zwei parallel zu dieser verlaufenden, gegensinnig rotierenden Ausgleichswellen, von denen eine über einen Trieb nach Art eines Kettentriebs an der Kurbelwelle angetrieben ist, während die andere Ausgleichswelle über einen Zahnradtrieb angetrieben ist, wobei Kettentrieb und Zahnradtrieb in unterschiedlichen Querebenen der Maschine liegen, dadurch gekennzeichnet, dass auch der Zahnradtrieb (10, 11) an der Kurbelwelle (5) angreift und sich die beiden Ausgleichswellen (6, 7) in unterschiedlichen axialen Bereichen der Maschine (1) erstrecken.Reciprocating internal combustion engine with a crankshaft and two parallel to this, in opposite directions rotating balancing shafts, one of which is about a shoot like a Chain drive is driven on the crankshaft while the other balance shaft over a gear drive is driven, wherein chain drive and gear drive lie in different transverse planes of the machine, characterized in that that the gear drive (10, 11) on the crankshaft (5) attacks and the two balance shafts (6, 7) in different axial Extend areas of the machine (1).
Description
Die Erfindung betrifft eine Hubkolben-Brennkraftmaschine gemäß dem Oberbegriff des Patentanspruchs 1. Derartige mit unsymmetrischen Ausgleichsmassen bestückte Ausgleichswellen dienen insbesondere dem Ausgleich der oszillierenden Massen der Brennkraftmaschine. Bei einer Vierzylinder-Reihen-Maschine werden derartige Ausgleichswellenanordnungen insbesondere zum Ausgleich der Massenkräfte zweiter Ordnung eingesetzt; bei Einzylindermaschinen lassen sich auf diese Weise die Massenkräfte erster Ordnung ausgleichen.The The invention relates to a reciprocating internal combustion engine according to the preamble of Claim 1. Such with asymmetrical balancing weights stocked Balancing shafts are used in particular to compensate for the oscillating Masses of the internal combustion engine. In a four-cylinder inline engine Such balance shaft arrangements are in particular to compensate the mass forces second order used; in single-cylinder engines can be in this way the mass forces balance first order.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Hubkolben-Brennkraftmaschine unter Wahrung ihrer Vorteile, insbesondere der Minimierung des Raumbedarfs, zu schaffen, die zur Vermeidung von Vibrationen durch Elastizitäten der verschiedenen Bauteile zugleich eine Minimierung des Wegs der Antriebsmomente für die Ausgleichswellen sicherstellt.Of the Invention is based on the object, a generic reciprocating internal combustion engine while preserving its benefits, in particular minimizing space requirements, to create, to avoid vibrations due to elasticities of different Components at the same time minimizing the path of the drive torques for the Ensures balance shafts.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbildungen der Erfindung beschreiben die Unteransprüche.The inventive solution this The object is the characterizing features of the main claim, advantageous embodiments of the invention describe the dependent claims.
In Abweichung von dem zitierten Stand der Technik werden der Kettentrieb und die Zahnräder also an axial voneinander entfernten Stellen der Maschine untergebracht, wodurch die Möglichkeit gegeben wird, auch die Ausgleichswellen sich über unterschiedliche axiale Bereiche der Maschine erstrecken zu lassen. Besonders vorteilhaft ist die im Anspruch 2 angegebene fluchtende Anordnung der Ausgleichswellen, beispielsweise unterhalb der Kurbelwelle, wodurch eine besonders schmalbauende Maschine erzielt wird.In Deviation from the cited prior art become the chain drive and the gears so housed at axially spaced locations of the machine, thus the possibility is given, even the balance shafts over different axial To extend areas of the machine. Especially advantageous is the specified in claim 2 aligned arrangement of the balance shafts, for example, below the crankshaft, creating a special narrow-building machine is achieved.
Eine insbesondere bei zum Quereinbau in Kraftfahrzeuge unerwünschte Verlängerung der Maschine durch die erfindungsgemäßen Maßnahmen kann dadurch vermieden werden, dass gemäß Anspruch 5 die Antriebe für die beiden Ausgleichswellen an Kurbelwangen der Kurbelwelle angeordnet werden, insbesondere durch Integration in die Kurbelwangen.A especially when transverse installation in motor vehicles unwanted extension the machine by the measures according to the invention can be avoided be that according to claim 5 the drives for arranged the two balance shafts on crank webs of the crankshaft be, especially by integration into the crank webs.
