Description

Ansaugleitung für Brennkraftmaschinen Es ist bekannt, Ansaugleitungen für Brennkraftm,aschinen in Form zweier ineinanderschiebbarer Rohre auszugestalten, um auf diese Weise die Gesamtlänge der Ansaugleitung den unterschiedlichen Betriebsbedingungen der Brennkraftmaschine, insbesondere unterschiedlichen Drehzahlen, anzupassen. Bei den bekannten Konstruktionen ist die Halterung des verschiebbaren äußeren Rohres je nach der Verschiebestellung unterschiedlich gut, indem die axiale Entfernung der Führungspunkte je nach Stellung variiert und somit die Kipp- und Verklemmungsgefahr bei den einzelnen Stellungen des äußeren Rohres stark unterschiedlich ist.Intake line for internal combustion engines It is known, intake lines to design for internal combustion engines in the form of two telescopic tubes, In this way, the total length of the suction line to suit the different operating conditions of the internal combustion engine, in particular to adapt to different speeds. at the known constructions is the mounting of the sliding outer tube depending on the shift position, differently well by increasing the axial distance the guide points vary depending on the position and thus the risk of tipping and jamming is very different in the individual positions of the outer tube.

Die Erfindung vermeidet diese Nachteile und besteht im wesentlichen darin, daß, vorzugsweise zu beiden Seiten, neben dem äußeren Rohr zwei feste, zur Rohrlängsachse parallele Führungen vorgesehen sind, an denen am äußeren Rohr angebrachte Führungsarme gleiten. während eine weitere Führung des äußeren Rohres an dem inneren Ende desselben durch das innere Rohr erfolgt.The invention avoids these disadvantages and essentially exists in that, preferably on both sides, in addition to the outer tube, two fixed, for Pipe longitudinal axis parallel guides are provided on which are attached to the outer pipe Guide arms slide. while a further guidance of the outer tube on the inner one The end of the same takes place through the inner tube.

Die erfindungsgemäße Konstruktion baut raum-und gewichtsparend und gibt dem äußeren Rohr eine Dreipunktlagerung. Hierbei ist je ein Punkt in der Halterung an den seitlichen Führungen und der dritte »Punkt« in der Berührungsstelle des inneren Endes des äußeren Rohres mit dem inneren Rohr zu sehen. Diese Dreipunktlagerung hat die Vorteile, daß keine Verklemmungen infolge mechanischer Überbestimmung der Lagerung zu befürchten sind, daß infolge des Konstantbleibens der Abstände der drei Punkte voneinander die Halterung des äußeren Rohres in allen Verschiebestellungen gleich gut ist und daß in-folge des Konstantbleibens der relativen Lage der drei Punkte zu dem äußeren Rohr irgendwelche an diesem Rohr angreifenden Kräfte, z. B. das Eigengewicht, stets in der gleichen, günstig ausgelegten Weise zu den drei Lagerpunkten weitergeleitet werden können.The construction according to the invention is space-saving and weight-saving and gives the outer tube a three-point mounting. Here you can see one point in the bracket on the side guides and the third "point" in the point of contact between the inner end of the outer tube and the inner tube. This three-point support has the advantages that no jamming is to be feared due to mechanical over-determination of the storage, that as a result of the constant staying of the distances of three points, the holder of the outer pipe in all displacement positions from each other is equally good, and that the result of the constant staying the relative position three points to the outer pipe any forces acting on this pipe, e.g. B. the dead weight, can always be forwarded to the three bearing points in the same, conveniently designed manner.

Im einzelnen wird vorgeschlagen, da,ß die beiden zur Rohrlängsachse parallelen Führungen aus Stangen bestehen und daß die Führungsarme entsprechende Bohrungen zum Umfassen der Stangen aufweisen. Bei Brennkraftrnaschinen, bei denen mehrere Ansaugleitungen nebeneinander angeordnet sind, ist es von Vorteil, wenn je zwei insbesondere gabelartig ineinandergreifende Führungsarme benachbarter Ansaugleitungen an ein und derselben Führungsstange gleiten. Es ist aus Vereinfachungsgründen günstig, wenn das Verstellglied, welches die Verschiebebewegung auf das äußere Rohr überträgt, jeweils nur an einem der beiden Führungsarme eines Rohres angreift. Insbesondere ergibt sich bei mehreren nebeneinanderliegenden Ansaugleitungen hierbei die Möglichkeit, daß für je zwei Ansaugleitungen nur ein an einem Führungsarm angreifendes Verstellglied vorgesehen zu werden braucht.In detail, it is proposed that the two to the pipe longitudinal axis parallel guides consist of rods and that the guide arms corresponding Have holes for encompassing the rods. In internal combustion engines where If several suction lines are arranged next to one another, it is advantageous if two, in particular, fork-like interlocking guide arms of adjacent suction lines slide on one and the same guide rod. For the sake of simplicity, it is cheap to if the adjusting element, which transmits the sliding movement to the outer tube, engages only on one of the two guide arms of a pipe. In particular If there are several suction lines lying next to each other, there is the possibility of that for every two suction lines only one adjusting member acting on a guide arm needs to be provided.

In konstruktiver Ausgestaltung wird für die Verstellung vorgeschlagen, daß eine vorzugsweise selbsttätig in Abhängigkeit von der Drehzahl betätigte, im Gebiet des inneren Rohres befindliche Querwelle angeordnet ist, an der Hebelarme befestigt sind, die über eine mit Kugelgelenken versehene Verstellstange die Führungsarme der äußeren Rohre und sornit diese selbst verschieben.In a structural design it is proposed for the adjustment, that a preferably operated automatically depending on the speed, im Area of the inner tube located cross shaft is arranged on the lever arms are attached, the guide arms via an adjusting rod provided with ball joints the outer tubes and move them yourself.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt Fig. 1 den Längsschnitt durch vier nebeneinander angeordnete erfindungsgemäße Ansaugleitungen, während Fig. 2 die Ansicht einer derartigen Ansaugleitung finit dem Verstellmechanismus entsprechend einem Schnitt nach der Linie 11-II von Fig. 1 darstellt.In the drawing, an embodiment of the invention is shown, namely, Fig. 1 shows the longitudinal section through four next to each other according to the invention Suction lines, while FIG. 2 is a finite view of such an intake line the adjusting mechanism corresponding to a section along the line 11-II of Fig. 1 represents.

Jede der vier Ansaugleitungen besteht aus einem inneren, mit dem Motorgehäuse 1 fest verbundenen rohrartigen Teil 2 und einem äußeren rohrartigen Teil 3, der sich über das Rohr 2 übergreifend verschieben kann. Die Ansaugluft strömt in Richtung der Pfeile A. Fest am Motor sind auf Fundamenten 4 Stangen 5 befestigt, die als oberen Abschluß eine Bundmutter 5 tragen. An den äußeren Rohren 3 sind Ringe 7 angeschweißt, die jeweils zu beiden Seiten, also um 180° versetzt, gegabelte Führungsarme 8 tragen. Die gegabelten Enden dieser Führungsarme weisen Bohrungen auf mit denen sie an den Stangen 5 gleiten. In jeder beliebigen Stellung (gezeichnet ist die Stellung .der größten Saugrohrlänge) werden die äußeren Rohre 3 einmal durch die beiden Führungsarme 8 in Verbindung mit den Stangen 5 und zum anderen durch die Schiebeführung an dem inneren Rohr 2 am unteren Ende 9 des äußeren Rohres 3 gehalten. Da sich die Entfernung zwischen 8 und 9 nicht ändert, ist das äußere Rohr in jeder beliebigen Verschiebestellung gleich gut gehalten und kann nicht kippen oder sich verklemmen.Each of the four intake lines consists of an inner one with the motor housing 1 firmly connected tubular part 2 and an outer tubular part 3, the can move across the pipe 2. The intake air flows in the direction of the arrows A. Firmly on the engine are fixed on foundations 4 rods 5, which as wear a collar nut 5 at the top. Rings 7 are welded to the outer tubes 3, each of which carries forked guide arms 8 on both sides, ie offset by 180 °. The forked ends of these guide arms have holes with which they are attached to the Rods 5 slide. In any position (the position .der largest suction tube length) the outer tubes 3 are once through the two guide arms 8 in conjunction with the rods 5 and on the other hand by the sliding guide on the inner tube 2 held at the lower end 9 of the outer tube 3. As the distance between 8 and 9 not changes, the outer tube is in any one Shift position held equally well and cannot tilt or jam.

D-ie Verstellung der äußeren Rohre 3 gegenüber dem inneren Rohreh 2 geschieht mit Hilfeeiner rahmen-, fest gelagerten Welle 10, an der ein Hebel 13 befestigt ist: Am Hebc7113 kann das Gestänge zu einem Flielikraftregl°r od. dgl. angeschlossen werden. Auf der Welle 10 sind ferner Hebel 11 befestigt, die über VerstellgliAer 12 an den Führungsarmen 8 angreifen. i Wie aus der Zeitiinung unimittelbar hervorgeht, werden hei d-r - Drehung der Welle 10 die äußeren Rohre 3 gegenül),er den inneren Rohren. 2 verschoben. Durch das gab;@lartige Ineinandergreifen der Führungsarrn:: B zweier benachbarter Rohre 3 wird er- i reicht, daß die er stellbewegung ohne jedes Klemmen von einem Rohr auf das andere übertragen wird. Das gilt b.--sonders für diejenigen Führungsarme, an denen kein Ver Stellglied 12 angreift.The adjustment of the outer tubes 3 with respect to the inner tube h 2 takes place with the aid of a frame-mounted shaft 10 on which a lever 13 is attached: On the Hebc7113 the linkage can become a flow force regulator or the like. be connected. On the shaft 10 levers 11 are also attached, which over Attack the adjustment members 12 on the guide arms 8. i As if straight from the newspaper it can be seen, he d-r - rotation of the shaft 10, the outer tubes 3 gegenül), er the inner tubes. 2 postponed. Through the gave; @l-like interlocking of the leaders: B of two adjacent tubes 3 is achieved that he adjusting movement without any Clamping is transferred from one pipe to the other. That applies b - especially for those guide arms on which no Ver actuator 12 engages.

Die Erfindung ist -nicht auf das dargestellte Ausführungsheispiel beschränkt. So kann z. B. der ,Durchmesser des -äußeren Rohres 3 kleiner sein als der Durchmesser des inneren Rohres 2.The invention is not limited to the illustrated embodiment limited. So z. B. the diameter of the outer tube 3 be smaller than the diameter of the inner tube 2.
