Description

Vorrichtung zum axialen Einstellen der,.Nockenwelle von Fahrzeugbrennkraftrnaschinen Es sind Einstellvorrichtungen für die Nockenwellen an Fahrzeugbrennkraftmas:chinen bekannt, bei denen das obere Ende einer senkrechten Zwischenwelle in einer Lagerhülse gelagert ist, die von außen durch einen Schrägschlitz nach beiden Seiten frei eingestellt werden kann. Hierdurch ist es möglich, den Eingriff der auf der Zwischenwelle und der Nockenwelle angeordneten Kegelräder grob einzuregulieren. Macht sich jedoch hierbei auch noch eine Verschiebung der Nockenwelle erforderlich, z. B. bei der Feineinstellung, so sind zeitraubende Zerlegungsarbeiten unumgänglich, da die Nockenwelle selbst bei diesen Einrichtungen von außen nicht einstellbar ist. Ebenfalls bekannt sind Einstellvorrichtungen für die 'Nockenwelle von Brennstoffpumpen, die ein Verschieben und gleichzeitiges Verdrehen der Nockenwelle nach beiden Seiten durch eine von außen bedienbare Gewindebüchse ermöglichen. Diese Gewindebüchse ist i11 einer am Pumpengehäuse befestigten Mutter geführt und wird mittels eines außerhalb des Gehäuses angeordneten Hebels verstellt.Device for the axial adjustment of the camshaft of vehicle internal combustion engines There are adjustment devices for the camshafts on Fahrzeugbrennkraftmas: chinen known in which the upper end of a vertical intermediate shaft in a bearing sleeve is mounted, which is freely set from the outside by an inclined slot on both sides can be. This makes it possible to engage the on the intermediate shaft and bevel gears arranged on the camshaft. However, it does this also requires a shift of the camshaft, for. B. at the Fine adjustment, so time-consuming disassembly work is inevitable, as the camshaft is not adjustable from the outside even with these facilities. Also known are adjustment devices for the 'camshafts of fuel pumps, which are shifting and simultaneous turning of the camshaft to both sides by one from the outside enable operable threaded bushing. This threaded bush is i11 one on the pump housing attached nut and is arranged by means of an outside of the housing Lever adjusted.

Demgegenüber erstreckt sich der Erfindungsgegenstand auf eine Vorrichtung zum axialen Einstellen der Nockenwelle von Fahrzeugbrennkraftmaschinen durch eine von außen bedienbare Stellschraube im Maschinengehäuse. Die Erfindung bietet den Vorteil, die Einstellung der laufenden Wellen zueinahder, die beim Einbau, wie auch bislang üblich, zunächst grob .einreguliert werden, dem Gehör nach mit Leichtigkeit vorzunehmen. Erfindungsgemäß ist die Stellschraube in die Stirnseite des glockenartig ausgebildeten Lagergehäuses eingeschraubt und in dem äußeren Gehäusedeckel unverschiebbar gelagert. Das Lager selbst ist auf der Nockenwelle fest angeordnet, so daß bei. einer axialen Verschiebung des Lagergehäuses durch die Stellschraube auch die Nockenwelle in axialer Richtung entsprechend verschoben wird.In contrast, the subject matter of the invention extends to a device for the axial adjustment of the camshaft of vehicle internal combustion engines by a Adjusting screw in the machine housing that can be operated from the outside. The invention offers the Advantage of adjusting the running shafts to each other when installing, as well Up to now common, initially roughly adjusted, according to the ear with ease to undertake. According to the invention, the adjusting screw in the face of the bell-like trained bearing housing screwed and immovable in the outer housing cover stored. The bearing itself is fixed on the camshaft, so that at. an axial displacement of the bearing housing by the adjusting screw also the camshaft is shifted accordingly in the axial direction.

Die Abbildung zeigt ein Ausführungsbeispiel nach dem Erfindungsgedanken im Längsschnitt, bei denn die Nockenwelle in all sich bekannter Weise unter Zwischenschaltung einer Königswelle von der Kurbelwelle aus angetrieben wird.The figure shows an embodiment according to the concept of the invention in longitudinal section, because the camshaft in a known manner with interposition a vertical shaft is driven by the crankshaft.

Auf der Nockenwellea ist ein in axialer Richtung verschiebbares Lager b angeordnet. In die Stirnseite e des glockenartig ausgebildeten Lagergehäuses,d ist eine in dem Gehäusedeckel e gelagerte Stellschraube j eingeschraubt. Durch Drehen des Schraubenkopfesä der Stellschraube i wird das Lager bt durch das Lagergehäuse d und damit auch die Nockenwelle a. in axialer Richtung verschoben. Durch eine entsprechende Einstellung des Schraubenkopfes g ist es daher möglich, die auf ,der Königswelle h und der Nockenwelle a .angeordneten Antriebskegelräder i bzw. h bei laufenden Wellen -genau miteinander in Eingriff zu bringen, .ohne daß irgendein Ausbau vorn Teilen des. Motors vorgenommen werden muß.A bearing b which is displaceable in the axial direction is arranged on the camshaft a. An adjusting screw j mounted in the housing cover e is screwed into the end face e of the bell-shaped bearing housing, d. By turning the screw headä of the adjusting screw i, the bearing bt is pushed through the bearing housing d and thus also the camshaft a. shifted in the axial direction. By adjusting the screw head g accordingly, it is possible to bring the drive bevel gears i or h arranged on the vertical shaft h and the camshaft a into engagement with one another while the shafts are running, without any dismantling of the parts of the motor must be made.
