Abstract
Description
Die Erfindung betrifft eine Einrichtung zur Betätigung von Gaswechselhubventilen einer Brennkraftmaschine umfassend eine Kurbelwelle, eine von dieser antreibbare Zwischenwelle, eine mit der Zwischenwelle verbundene Kupplung sowie eine mittels der Kupplung mit der Zwischenwelle verbindbare Getriebeeinrichtung mit wenigstens einer Getriebewelle, wobei zur Betätigung der Gaswechselhubventile steuerelementgetriebene Nockenwellen vorgesehen sind.The The invention relates to a device for actuating gas exchange lift valves an internal combustion engine comprising a crankshaft, one of these drivable intermediate shaft, one connected to the intermediate shaft Coupling and connectable by means of the coupling with the intermediate shaft Transmission device with at least one transmission shaft, wherein the activity the gas exchange valves tax-driven camshafts are provided.

Der Erfindung liegt daher die Aufgabe zugrunde, eine eingangs genannte Brennkraftmaschine noch kompakter auszugestalten und insbesondere den Ventiltrieb in bezug auf den Bauraum zu optimieren. Darüber hinaus sollen das Leistungsgewicht der Brennkraftmaschine erhöht, der Kraftstoffverbrauch gesenkt und der Herstellungs- und Montageaufwand reduziert werden.Of the Invention is therefore based on the object, an aforementioned Internal combustion engine even more compact design and in particular the Valve gear with respect to the space to optimize. Furthermore should increase the power of the engine, the Reduced fuel consumption and reduced the manufacturing and assembly costs become.
Die Lösung der Aufgabe erfolgt mit den Merkmalen des Anspruchs 1, wobei erfindungsgemäß vorgeschlagen wird, mit der Zwischenwelle drehfest ein Antriebszahnrad zu verbinden, welches mit wenigstens einem auf der wenigstens einen Getriebewelle drehbar angeordneten Doppelzahnrad zum Antrieb einer Steuerkette korrespondiert. Aufgrund der Lagerung des wenigstens einen Doppelzahnrads auf der wenigstens einen Getriebewelle kann eine weitere Zwischenwelle eingespart werden, sodass der Bauraum deutlich verringert und damit das Leistungsgewicht der Brennkraftmaschine erhöht, der Kraftstoffverbrauch gesenkt und der Herstellungs- und Montageaufwand reduziert werden kann. Auch die Ausführung des Doppelzahnrads mit einer Verzahnung zum Antrieb des Steuerelements und einer mit dem Zahnrad der Zwischenwelle korrespondierenden weiteren Verzahnung trägt zur Lösung der erfindungsgemäßen Aufgabe bei.The solution The object is achieved with the features of claim 1, wherein proposed according to the invention is, with the intermediate shaft rotatably connect a drive gear, which with at least one on the at least one transmission shaft rotatably mounted double gear to drive a timing chain corresponds. Due to the storage of the at least one double gear on the at least one transmission shaft, a further intermediate shaft can be saved so that the space significantly reduced and thus the Performance weight of the internal combustion engine increases, fuel consumption lowered and the manufacturing and assembly costs can be reduced. Also the execution of the double gear with a toothing for driving the control element and one corresponding to the gear of the intermediate shaft further Gearing bears to the solution the task of the invention at.
Besonders vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Especially advantageous embodiments and refinements of the invention are Subject of the dependent claims.
Gemäß eines besonders zu bevorzugenden Ausführungsbeispiels der Erfindung ist das wenigstens eine Doppelzahnrad auf der wenigstens einen Getriebewelle wälzgelagert. Mit der Wälzlagerung ist trotz den von der Brennkraftmaschinendrehzahl bzw. der Fahrzeuggeschwindigkeit abhängigen unterschiedlichen, wechselnden, bereichsweise auch hohen Drehzahlen des Doppelzahnrads respektive der Getriebewelle(n) eine wartungsfreie und betriebssichere Lagerung gewährleistet.According to one particularly preferable embodiment The invention is the at least one double gear on the at least a gear shaft roller bearings. With the roller bearing is in spite of the different depending on the engine speed and vehicle speed, changing, sometimes even high speeds of the double gear respectively the transmission shaft (s) a maintenance-free and reliable Storage guaranteed.
Sehr vorteilhaft ist es, wenn die Getriebeeinrichtung eine erste und eine zweite Getriebewelle umfasst und das Antriebszahnrad mit einem auf der ersten Getriebewelle angeordneten und einem auf der zweiten Getriebewelle angeordneten Doppelzahnrad korrespondiert. Beispielsweise weist das Getriebe eine Eingangs- und eine Ausgangswelle auf, wobei ein besonders kompakter Aufbau dadurch erreicht ist, dass das Antriebszahnrad mit zwei Doppelzahnrädern gleichzeitig in Eingriff steht.Very It is advantageous if the transmission device has a first and a second transmission shaft and the drive gear with a arranged on the first gear shaft and one on the second Gear shaft arranged double gear corresponds. For example the transmission has an input and an output shaft, wherein a particularly compact construction is achieved in that the drive gear with two double gears at the same time engaged.
Zweckmäßigerweise umfasst die Brennkraftmaschine zwei Zylinder in Boxerbauweise, wobei die Gaswechselhubventile eines jeden Zylinders ausgehend von jeweils einem Doppelzahnrad mittels eines Steuerelements antreibbar sind.Conveniently, the internal combustion engine comprises two cylinders in boxer construction, wherein the Gaswechselhubventile each cylinder starting from each a double gear by means of a control can be driven.
Nachfolgend wird ein besonders zu bevorzugendes Ausführungsbeispiel der Erfindung unter Bezugnahme auf Figuren näher erläutert, dabei zeigen schematisch und beispielhaftfollowing becomes a particularly preferable embodiment of the invention with reference to figures closer explains thereby show schematically and by way of example
