Description
Die Erfindung betrifft eine Vorrichtung zur Reduzierung von Schallemissionen gemäß dem Merkmal im Oberbegriff des Patentanspruches 1.The The invention relates to a device for reducing noise emissions according to the characteristic in the preamble of claim 1.

Patentanmeldung
Nachteilig an der beschriebenen Ausgestaltung ist es, dass eventuell auftretende Relativbewegungen zwischen dem Luftsammeltrakt der Brennkraftmaschine und einem, die Ansaugluft liefernden Bauteil, durch zusätzliche Entkopplungsmaßnahmen entkoppelt werden müssen. Dies gilt auch für aufgeladene Brennkraftmaschinen, bei denen nach einer Ladepumpe die aufgeheizte Ansaugluft in einem Ladeluftkühler abgekühlt werden muss, bevor sie der Brennkraftmaschine zugeführt wird. Üblicherweise sind derartige Ladeluftkühler ortsfest zur Karosserie des Kraftfahrzeuges angeordnet, während der Luftsammeltrakt ortsfest zur Brennkraftmaschine ist.adversely What is important about the described configuration is that it may occur Relative movements between the air collecting tract of the internal combustion engine and a component that supplies the intake air by additional Decoupling measures decoupled Need to become. This also applies to supercharged internal combustion engines, in which after a charge pump The heated intake air must be cooled in an intercooler before it can be used in the internal combustion engine supplied becomes. Usually are such intercoolers arranged stationary to the body of the motor vehicle, during the Air collecting tract is stationary to the internal combustion engine.
Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Vorrichtung zur Reduzierung von Schallemissionen aufzuzeigen, mit der es möglich ist Relativbewegungen zwischen dem Ansaugtrakt einer Brennkraftmaschine und zur Karosserie ortsfesten Bauteilen auszugleichen.task The present invention is a generic device to demonstrate the reduction of noise emissions with which it is possible Relative movements between the intake tract of an internal combustion engine and to compensate for the stationary components.
Diese Aufgabe ist durch das Merkmal im kennzeichnenden Teil des Patentanspruches 1 gelöst.This Task is by the feature in the characterizing part of the claim 1 solved.
In vorteilhafter Weise ist das Gehäuse ein flexibler Faltenbalg. Durch diese Ausgestaltung wird das Gehäuse einerseits mit dem Luftansaugrohr und andererseits mit einem karosseriefesten, luftzuführenden Bauteil verbunden. Somit dient ein Abschnitt des Gehäuses zur Reduzierung der Schallemission, während der andere Abschnitt des Gehäuses als flexible Verbindung zwischen einem zur Brennkraftmaschine ortsfesten Luftsammeltrakt und einem zur Karosserie ortsfesten, luftführenden Bauelement dient.In the housing is advantageous a flexible bellows. This configuration makes the housing one hand with the air intake pipe and on the other hand with a body-fixed, air-supplying Component connected. Thus, a portion of the housing is used Reduction of noise emissions while the other section of the housing as a flexible connection between a fixed to the internal combustion engine Air collecting tract and an air duct that is fixed to the body Component serves.
Damit keine Fehlluft ausgeblasen wird, ist das Gehäuse gemäß Patentanspruch 2 sowohl gegenüber dem gasführenden Rohr, als auch dem gasführenden Bauelement gasdicht verschlossen.In order to no incorrect air is blown out, the housing according to claim 2 is both against the gas-bearing Pipe, as well as the gas-carrying Component sealed gastight.
Mit der erfindungsgemäßen Vorrichtung kann der Luftsammeltrakt gemäß Patentanspruch 3 direkt mit der Druckseite des Laders oder eines Ladeluftkühlers verbunden werden.With the device according to the invention can the air collecting tract according to claim 3 directly connected to the pressure side of the charger or an intercooler become.
Eine Ausgestaltung gemäß der Patentansprüche 4 bis 6 stellt sicher, dass die Öffnungen immer im Bereich eines ausgebuchteten Bereichs des Gehäuses angeordnet sind. Für den Fall, dass mehrere Öffnungen in Strömungsrichtung hintereinander angeordnet sind, können diese in unterschiedliche Kammern, d. h. in verschiedenen Falten des Gehäuses, münden. Da die eingeschnürten Bereiche, durch Stabilisierungselemente, hier Drahtringe, fest auf das Luftansaugrohr gedrückt werden, entstehen einzelne, separate, voneinander unabhängige und akustisch entkoppelte Resonatorkammern. Ferner dienen die Stabilisierungselemente der zusätzlichen Befestigung des Gehäuses auf dem Luftansaugrohr.A Design according to claims 4 to 6 ensures that the openings always arranged in the area of a bulged area of the housing are. For the case that multiple openings in the direction of flow are arranged one behind the other, they can be in different chambers, d. H. in different folds of the housing. Because the constricted areas, by means of stabilizing elements, here wire rings, firmly on the air intake pipe depressed single, separate, independent and acoustic decoupled resonator chambers. The stabilizing elements also serve the additional Fastening the housing on the air intake pipe.
Gemäß Patentanspruch 7 und 8 erstrecken sich die ausgebuchteten und die eingeschnürten Bereiche radial um das Luftansaugrohr. Einem, bzw. jedem ausgebuchteten Bereich können mehrere Öffnungen zugeordnet sein. Durch diese Anordnung ist einerseits eine optimale Schwingungsisolierung zwischen dem zur Brennkraftmaschine ortsfesten Bauteil und dem zur Karosserie ortsfesten Bauteil gewährleistet, während gleichzeitig die Öffnungen im Luftansaugrohr über den gesamten Umfang verteilt werden können.According to claim 7 and 8 extend the bulged and the constricted areas radially around the air intake pipe. One or each booked area can multiple openings be assigned. This arrangement is optimal on the one hand Vibration isolation between the stationary to the internal combustion engine Component and the component that is stationary with respect to the body, while the openings at the same time in the air intake pipe the entire scope can be distributed.
Über die Anzahl der Bohrungen, deren Öffnungsquerschnitt in Verbindung mit dem Volumen der einzelnen ausgebuchteten Bereiche wird gemäß Patentanspruch 9 eine Resonatorkammer gebildet, deren Dämpfungsfrequenzband von den zuvor genannten Parametern abhängig ist. Durch eine Abstimmung der Parameter (Anzahl der Öffnungen in Verbindung mit deren Querschnittsfläche und Volumen der ausgebuchteten Bereiche) wird die bestmögliche akustische Reduzierung der Schallemission erzielt.About the Number of holes whose cross section in connection with the volume of the individual booked areas is according to claim 9 a resonator chamber formed, the damping frequency band of the previously mentioned parameters dependent is. By coordinating the parameters (number of openings in connection with their cross-sectional area and volume of the bulged Areas) will be the best possible acoustic reduction of noise emissions achieved.
