Abstract
Description
Die Erfindung betriff einen Nockenwellenversteller für Brennkraftmaschinen, der koaxial zu einer Nockenwelle angeordnet ist und einen drehfest mit der Nockenwelle verbundenen Rotor und einen von einer Kurbelwellwelle angetriebenen Stator umfasst, nach dem Oberbegriff des Patentanspruchs 1.The Invention relates to a camshaft adjuster for internal combustion engines, the is arranged coaxially to a camshaft and a rotationally fixed with the Camshaft connected rotor and one of a crankshaft shaft driven stator comprises, according to the preamble of the claim 1.

Es ist Aufgabe der Erfindung einen Nockenwellenversteller für Brennkraftmaschinen zu schaffen, der bei guter Funktion sich durch baulich günstige Verhältnisse gerade im Bereich der Spannschraube und dem Steuerschieber auszeichnet.It The object of the invention is a camshaft adjuster for internal combustion engines to create, in good working order by structurally favorable conditions just in the area of the clamping screw and the spool is characterized.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention this Problem solved by the features of claim 1. Further, the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass die Ausbildung des als Hülse dargestellten Steuerschiebers und die Anordnung der Spannschraube im Innenraum der Hülse räumlich günstige Verhältnisse schafft und ein gute Funktion des Steuerschiebers und damit auch des Nockenwellenverstellers sichert. Die Zuführung des ersten Öldrucks und des zweiten Öldrucks an den Steuerschieber lässt sich zum einen mit vertretbaren Mitteln umsetzen und zum anderen trägt sie zum sicheren Betrieb des Nockenwellenverstellers bei. Sinngemäß trifft dies auch für Ringräume für den ersten Öldruck und den zweiten Druckraum zu. Auch leisten die Ringkörper, die besagte Ringräume begrenzen zur Konstruktionsvereinfachung bei. Schließlich bewirkt die schaltbare Freilaufeinrichtung eine Ausnützung von Wechselmomenten der Nockenwelle, und zwar zur Realisierung von Verstellbewegungen des Rotors des Nockenwellenverstellers.The with the invention mainly The benefits achieved are to be seen in the fact that the training of the Sleeve shown Spool and the arrangement of the clamping screw in the interior the sleeve spatially favorable conditions creates and a good function of the spool and so too the camshaft adjuster secures. The supply of the first oil pressure and the second oil pressure leaves on the spool on the one hand implement with justifiable means and on the other she wears for safe operation of the camshaft adjuster. Corresponds to this also for annular spaces for the first oil pressure and the second pressure chamber too. Also afford the ring body, the said annular spaces limit to the design simplification at. Finally causes the switchable freewheel device exploitation of alternating moments of the Camshaft, and indeed for the realization of adjusting movements of the Rotor of the camshaft adjuster.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher beschrieben wird.In The drawing is an embodiment of the invention, which will be described in more detail below.
