Description

Gegenstand der erfindung ist eine Einrichtung, die es gestattet,The subject of the invention is a device that allows

die Steuerzeiten bzw. -winkel der Nockenwellen eines Otto- oder Dieselviertaktmotores entsprechend den Erfordernissen während des Betriebes in ihrer Lage zueinander und zur Kurbelwelle zu verändern.the timing or angle of the camshafts of a gasoline or diesel four-stroke engine according to the requirements during operation in their position to each other and to change the crankshaft.

Die Steuerzeiten der Nockenwellen für die win- und Auslaßventile beeinflussen das Lauf-, Leistungs-, Drehmoment- und Abgasverhalten des Verbrennungsmotors. Sie stellen daher stets einen Kompromiß zwischen diesen Anforderungen dar.Influence the timing of the camshafts for the win and exhaust valves the running, power, torque and exhaust gas behavior of the internal combustion engine. she therefore always represent a compromise between these requirements.

Die nachfolgend beschriebene Verstelleinrichtung ermöglicht eine geringe Ventilüberschneidung und damit wenig Abgasrückströmung in den Frischgaskanal bei niedrigen Drehzahlen und eine größere Überschneidung bei beßserer Leistungsausbeute im höheren Drehzahlbereich.The adjustment device described below allows a small Valve overlap and thus little exhaust gas flow back into the fresh gas duct low speeds and a greater overlap with better power output in the higher speed range.

Als weitere Einflußparameter kommen in Frage: - Unterdruck im Ansaugrohr - Luftdruck und-temperatur - Schmieröl- und Kühlwassertemperatur - Sauerstoffgehalt im Abgas (R -Sonde) - Abgastemperatur - Klopfsensor - Kraftstoffdurchfluß Diese Werte werden in einem Mikrorechner verarbeitet und mit gespeicherten motorspezifischen Eennfelddaten verglichen.Further influencing parameters are: - Negative pressure in the intake pipe - Air pressure and temperature - Lubricating oil and cooling water temperature - Oxygen content in the exhaust gas (R probe) - exhaust gas temperature - knock sensor - fuel flow rate These Values are processed in a microcomputer and stored with engine-specific values Eennfeld data compared.

Der daraus gebildete Stellbefehl wirkt huber geeignete Kraftverstarker auf die Nockenwellenverrstelleinrichtung.The control command formed from this acts via suitable power amplifiers on the camshaft adjusting device.

Beschreibung der Verstelleinrichtung Das Antriebszahnrad 1 ist auf der Nockenwelle 7 drehbar gelagerbt. Auf der Innenseite ist es mit schräg zur Achse angeordneten Kugellaufbahnen versehen.Description of the adjustment device The drive gear 1 is rotatably mounted on the camshaft 7. On the inside it is provided with ball tracks arranged at an angle to the axis.

Die Kugeln 2 übertragen das Drehmoment auf die Hülse 4, die ebenfalls schräggestellte Kugellaufbahnen besitzt. Die Schrägstellung ist jedoch entgegengesetzt zum Antriebsrad.The balls 2 transmit the torque to the sleeve 4, which also Has inclined ball tracks. However, the inclination is opposite to the drive wheel.

Über das Drucklager 6 verändert der Verschiebekäfig 3 die Lage der Kugeln 2 in axialer Richtung Damit verändert sich die Lage der angetriebenen Nockenwelle 7 zum Antriebszahnrad 1 in ihrem Winkel zueinander.About the thrust bearing 6 of the sliding cage 3 changes the position of the Balls 2 in the axial direction This changes the position of the driven camshaft 7 to the drive gear 1 in their angle to each other.

Der Kraftschluß bleibt dabei jederzeit erhalten.The frictional connection is retained at all times.
