Abstract
Description
Gebiet der ErfindungTerritory of invention
Die Erfindung betrifft eine Verdrehsicherungsleiste für den Ventiltrieb einer Brennkraftmaschine, mit in der Leiste in Abständen hintereinander angeordneten Aufnahmeräumen für die Aufnahme von eingesteckten, als Rollenstößel ausgebildeten Ventilstößeln, wobei jeweils zur Sicherung eines Rollenstößels gegen Verdrehen um seine zentrale Längsachse an seiner Mantelfläche zwei parallele Verdrehsicherungsflächen in der Form von ebenen Abflachungen ausgebildet sind, welche an Führungsflächen der Verdrehsicherungsleiste abgestützt sind, die sich innerhalb des zugehörigen Aufnahmeraums befinden, und wobei dem Aufnahmeraum der Verdrehsicherungsleiste eine als Schlüsselloch bezeichnete Einführöffnung zugeordnet ist, in welche der jeweilige Rollenstößel in Richtung seiner Längsachse eingesteckt, anschließend zu den der Verdrehsicherung dienenden Führungsflächen der Verdrehsicherungsleiste hin achsparallel verschoben und danach erneut in Achsrichtung verlagert wird.The invention relates to an anti-rotation bar for the Valve train of an internal combustion engine, arranged one after the other in the bar at intervals receiving spaces for the Inclusion of inserted valve tappets designed as roller tappets, wherein each to secure a roller tappet against twisting around its central longitudinal axis on its lateral surface two parallel anti-rotation surfaces in the form of flat flats are formed, which on guide surfaces of the Anti-rotation bar supported are located within the associated recording room, and wherein the receiving space of the anti-rotation bar is a keyhole designated insertion opening assigned into which the respective roller tappet is inserted in the direction of its longitudinal axis, subsequently to the anti-rotation guiding surfaces of the anti-rotation bar moved parallel to the axis and then shifted again in the axial direction becomes.
Eine solche Führungsleiste wird zur Verhinderung von Verdrehungen von Ventilstößeln, die als Rollenstößel ausgebildet sind, in Brennkraftmotoren einge setzt. Sie dient gleichzeitig als Montagehilfe und kann speziell für die Rollenstößel eines Stoßstangenventiltriebes verwendet werden.Such a guide bar is used for prevention of twisting of valve lifters, the designed as a roller tappet are used in internal combustion engines. It also serves as Assembly aid and can be specially designed for the roller tappets one Bumper valve train be used.

Der Erfindung liegt die Aufgabe zugrunde, eine Rollenstößel-Montage- und Verdrehsicherungsleiste zu schaffen, die eine eindeutige Ausrichtung des Stößels in der Leiste und damit auch im Motor gewährleistet, wie dies für einen schaltbaren Rollenstößel erforderlich ist. Derartige Stößel müssen definiert im Motorblock eingebaut werden können, d.h. der Schaltmechanismus dieser Stößel muß auf der Seite der Schaltölgalerien liegen. Die Stößel müssen in eingesetzter Position verdrehgesichert sein. Die Verdrehsicherungsleiste soll so ausgelegt sein, daß sie zusammen mit sechs Stößeln als Baugruppe verbaut werden kann. Außerdem darf dies nur in einer Position und auf einer Seite des Motorblocks möglich sein. Die Stößel sollen in der Verdrehsicherungsleiste gehalten werden, um nicht zu leicht wieder herausfallen zu können.The invention has for its object a Roller plunger-assembly and anti-rotation bar to create a clear orientation of the Pestle in the bar and thus also in the engine, like this for one switchable roller tappet required is. Such plungers must be defined can be installed in the engine block, i.e. the switching mechanism of this tappet must be on the side of the switching oil gallery lie. The plungers must be in inserted position must be secured against rotation. The anti-rotation bar should be designed so that it together with six pestles as Assembly can be installed. In addition, this may only be in one position and be possible on one side of the engine block. The plungers should be held in the anti-rotation bar so as not to be too light to be able to fall out again.
Erfindungsgemäß wird vorgeschlagen, daß an der Verdrehsicherungsleiste im Bereich der Ausnehmung eine vorstehende Nase angeordnet und in den Rollenstößel im Bereich einer Verdrehsicherungsfläche eine radiale Nut eingearbeitet ist, welche bei der achsparallelen Verschiebung des Rollenstößels die Nase der Verdrehsicherungsleiste umgreift.According to the invention it is proposed that at the Anti-rotation bar in the area of the recess a protruding Arranged nose and a in the roller tappet in the area of an anti-rotation surface radial groove is incorporated, which in the axis-parallel displacement of the roller tappet Grips nose of the anti-rotation bar.
Nach einem weiteren Vorschlag ist erfindungsgemäß jeweils an einem Rollenstößel zur Sicherung gegen dessen Verdrehung um seine zentrale Längsachse eine rechteckige Blechscheibe befestigt, welche den Rollenstößel umgibt, wobei zwei parallele, als Verdrehsicherungsflächen wirkende Längsseiten der Blechscheibe des in den Aufnahmeraum eingesteckten Rollenstößels sich mit Führungsflächen der Verdrehsicherungsleiste im Eingriff befinden.After another suggestion is according to the invention in each case on a roller tappet Securing against its rotation around its central longitudinal axis attached a rectangular sheet metal disk that surrounds the roller tappet, whereby two parallel, long sides acting as anti-rotation surfaces the sheet metal disc of the roller tappet inserted into the receiving space itself with guide surfaces of the Anti-rotation bar are engaged.
