Definitions
- the invention relates to a device for reducing noise emissions according to the feature in the preamble of claim 1.
- a disadvantage of the described configuration is that it may occur Relative movements between the air collecting tract of the internal combustion engine and one, the component supplying the intake air, by additional Decoupling measures must be decoupled. This also applies to supercharged internal combustion engines, in which after a charge pump heated intake air must be cooled in an intercooler before it is fed to the internal combustion engine. Such intercoolers are usually used arranged stationary to the body of the motor vehicle, during the Air collecting tract is stationary to the internal combustion engine.
- the object of the present invention is to provide a generic device for To show the reduction of noise emissions with which it is possible Relative movements between the intake tract of an internal combustion engine and Balance body fixed components.
- the housing is advantageously a flexible bellows.
- the housing is connected on the one hand to the air intake pipe and on the other hand to a body-fixed, air-supplying component.
- one section of the housing serves to reduce the noise emission, while the other section of the housing serves as a flexible connection between an air collecting tract fixed to the internal combustion engine and an air-guiding component fixed to the body.
- the housing is according to claim 2 both opposite the gas-carrying pipe and the gas-carrying pipe Component sealed gastight.
- the air collecting tract according to Claim 3 directly with the pressure side of the charger or an intercooler get connected.
- An embodiment according to claims 4 to 6 ensures that the Openings always in the area of a bulged area of the housing are arranged. In the event that several openings in the direction of flow Arranged one behind the other, these can be in different chambers, i.e. H. in various folds of the housing, open out. Because the constricted areas, by means of stabilizing elements, here wire rings, firmly on the air intake pipe single, separate, independent and acoustically decoupled resonator chambers. Furthermore, the serve Stabilizing elements of the additional attachment of the housing on the Air intake pipe.
- the bulged and the constricted areas radially around the air intake pipe One or everyone bulged area can be assigned several openings. Through this The arrangement is on the one hand an optimal vibration isolation between the Internal combustion engine fixed component and the component fixed to the body guaranteed while at the same time the openings in the air intake pipe over the entire scope can be distributed.
- a resonator chamber is formed, the damping frequency band of which previously mentioned parameters is dependent.
- Figure 1 shows the top view of a sectional view of an inventive Device for reducing noise emissions. It is a section of one Air intake pipe 1 shown, which at one end radially at its Has outer circumference openings 2, 2 '. The openings 2, 2 'are in three radial Circumferential sections arranged separately. The single ones Circumferential sections are each radially connected to the air intake pipe 1 enclosing groove 6, 6 'separated from each other. Radially around that with bores 2, 2 ' provided end of the air intake pipe 1 is a housing 3, a tubular Bellows, arranged. The housing 3 has bulged areas 3a, 3a ' and constricted areas 3b, 3b '.
- Each constricted area 3b, 3b ' is from a stabilizing element 4, 4 ', each a wire ring, in which each correspond Groove 6, 6 'held.
- the housing 3 forms an extension of the air intake pipe 1
- the extension is with another closure element 7 'on another gas-carrying component 5 attached.
- This closure element 7 ' is also one commercially available clamp. While the air intake pipe 1 is fixed to the internal combustion engine, the gas-carrying component 5 is arranged fixed to the body. in the The gas-carrying component 5 is a flange of an exemplary embodiment Intercooler, but it can also be a charger flange or other gas-carrying Component. Also a reverse attachment with respect to the body and the Internal combustion engine is possible.
- the housing 3 serves as sound-absorbing housing, with the air intake noise, as well as noise for example, a loader, can be effectively damped.
- the housing 3 meets the Double function of sound attenuation on the one hand and vibration isolation on the other hand.
- the housing 3 is a polymer-based one Bellows, however, can also use other flexible building materials, such as Silicones or rubber.

Abstract
Description
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.
