Description
Die Erfindung betrifft eine Schaltwalze insbesondere zur Verwendung in einer Saugrohranlage für eine Mehrzylinderbrennkraftmaschine nach dem Oberbegriff des Hauptanspruchs.The invention relates to a shift drum, in particular for use in a Saugrohranlage for a multi-cylinder internal combustion engine according to the preamble of the main claim.

Der DE 43 44 504 Al ist eine Saugrohranlage für eine Mehrzylinder-Brennkraftmaschine mit einem Ansaugverteiler, nebeneinander angeordneten ersten Einzelsaugrohren, zweiten Einzelsaugrohren, die von dem Ansaugverteiler ausgehen und jeweils in ein erstes Einzelsaugrohr münden, und einer Einrichtung zum Absperren oder Freigeben der zweiten Einzelsaugrohre zu entnehmen, wobei der Ansaugverteiler und die ersten und zweiten Einzelsaugrohre von einem einstückigen Bauteil gebildet sind, das eine alle zweiten Einzelsaugrohre schneidende Längsbohrung aufweist, und daß in dieser Längsbohrung eine Schaltwalze eingesetzt ist, die für jedes zweite Einzelsaugrohr einen Durchbruch aufweist.DE 43 44 504 A1 is an intake manifold for a multi-cylinder internal combustion engine with a Ansaugverteiler, juxtaposed first Einzelsaugrohren, second Einzelsaugrohren that emanate from the intake manifold and each lead into a first Einzelsaugrohr, and means for shutting off or releasing the second Einzelsaugrohre refer, wherein the intake manifold and the first and second Einzelsaugrohre are formed by a one-piece component having an all second Einzelsaugrohre intersecting longitudinal bore, and in that longitudinal bore a shift drum is used, which has an opening for every second Einzelsaugrohr.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Schaltwalze, insbesondere für eine Saugrohranlage zu schaffen, die einfach aufgebaut ist und bei welcher Fertigungstoleranzen keinen Einfluss auf die Dichtheit des Systems haben. Diese Aufgabe wird, ausgehend von dem Oberbegriff des Hauptanspruchs, durch dessen kennzeichnende Merkmale gelöst.The invention is therefore an object of the invention to provide a shift drum, in particular for a Saugrohranlage, which is simple and in which manufacturing tolerances have no effect on the tightness of the system. This object is achieved on the basis of the preamble of the main claim by its characterizing features.
Der Vorteil der Erfindung liegt darin, dass die Schaltwalze mit wenigstens einem federwirksamen Element versehen ist, welches in der geschlossenen Stellung der Schaltwalze die Dichtwirkung derselben unterstützt. Dieses federwirksame Element kann aus einem Kunststoff oder einem anderen geeigneten Werkstoff hergestellt sein. In der geschlossen Stellung liegt dieses Element erfindungsgemäß vollflächig an der Kanalöffnung der Einzelsaugrohre an und dichtet diese ab. Das federwirksame Element kann sowohl auf der Eintrittsseite jedes Einzelsaugrohres, als auch auf der Austrittsseite jedes Einzelsaugrohres angeordnet sei.The advantage of the invention is that the shift drum is provided with at least one spring-effective element which supports the sealing effect of the same in the closed position of the shift drum. This spring-active element may be made of a plastic or other suitable material. In the closed position of this element according to the invention is the entire surface of the channel opening of the individual suction and seals it off. The spring-active element can be arranged both on the inlet side of each individual intake manifold, as well as on the outlet side of each individual intake manifold.
Bei der Anordnung ist lediglich zu beachten, dass Querströmungen in der Längsbohrung vermieden werden. In einer Ausgestaltung der Erfindung ist vorgesehen, das federwirksame Element als Blattfeder zu gestalten, wobei diese an dem Drehschieber mit einer Rastverbindung oder einer Nietverbindung befestigt werden kann. Die Befestigung erfolgt zweckmäßigerweise in der Mitte der Blattfeder. Eine weitere Ausgestaltung der Erfindung sieht vor, die Längsbohrung mit einem elastischen Wandteil zu gestalten. Dieses elastische Wandteil dient ebenfalls zur Toleranzkompensation und erzeugt ferner eine Klemmwirkung auf die Schaltwalze. Eine weitere Möglichkeit zur Abdichtung der Einzelsaugrohre mit einem federwirksamen Element sieht vor, dieses als Druckfeder so auszugestalten, dass es eine Kraft ausübt, die die Schaltwalze zu der Öffnung der Einzelsaugrohre hinbewegt und damit die Dichtwirkung verbessert. Ein solches federwirksames Element ist an der Schaltwalze eingerastet und kann aus Kunststoff oder einem anderen geeigneten Werkstoff bestehen.In the arrangement, it should only be noted that transverse flows in the longitudinal bore are avoided. In one embodiment of the invention provided to make the spring-active element as a leaf spring, which can be attached to the rotary valve with a snap-in connection or a rivet connection. The attachment is conveniently carried out in the middle of the leaf spring. A further embodiment of the invention provides to make the longitudinal bore with an elastic wall part. This elastic wall part also serves for tolerance compensation and also generates a clamping action on the shift drum. Another way to seal the individual intake with a spring-effective element provides this as a compression spring in such a way that it exerts a force that moves the shift drum to the opening of the individual intake and thus improves the sealing effect. Such a spring-active element is latched to the shift drum and may be made of plastic or other suitable material.
In einer Weiterbildung der Schaltwalze besteht diese aus einzelnen Segmenten, wobei jedes Segment einem Einzelsaugrohr zugeordnet ist. Die Segmente sind miteinander torsionssteif verbunden, andererseits sind sie radialbeweglich angeordnet, so dass auch hier ein Toleranzausgleich stattfinden kann. Zur Vermeidung einer Querströmung in der Längsbohrung kann die Schaltwalze auf den zwischen den Einzelsaugrohren verlaufenden Abschnitten mit Dichtungen oder Dichtungsringen ausgestattet sein. Diese sind nach Art einer Kolbenringdichtung gestaltet.In a further development of the shift drum, this consists of individual segments, each segment is associated with a Einzelsaugrohr. The segments are torsionally rigidly connected to each other, on the other hand, they are arranged radially movable, so that even here tolerance compensation can take place. To avoid a transverse flow in the longitudinal bore, the shift drum may be equipped on the running between the individual intake manifold sections with seals or gaskets. These are designed in the manner of a piston ring seal.
Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and other features of preferred embodiments of the invention will become apparent from the claims and from the description and drawings, wherein the individual features are realized individually or in each case in the form of sub-combinations in the embodiment of the invention and in other fields and can represent advantageous and protectable versions for which protection is claimed here.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert.The invention will be explained in more detail with reference to embodiments.
