    Component of an exhaust gas system The invention relates to a component of an exhaust gas system for an internal combustion engine, having a wall in which at least one port is provided, and a perforated cover associated with the orifice.
    The component may be an exhaust gas-conducting pipe or a housing in which a catalyst substrate or a particulate filter is for example arranged, or may be a silencer. The internal combustion machine may in particular be an engine for a motor vehicle that operates according to the Otto principle or the Diesel principle.
    Examples for such a component are found in DE 10 2012 014 620 A1 and WO 2014/126548 A1. The orifice in the wall of the component covered with the perforated cover serves for the damping of noise when the component is traversed by exhaust gas. Due to the gas flow (even low) through the orifice, fewer resonances are produced by standing waves within the component. The turbulent currents in the exhaust stream are further attenuated and converted to laminar currents, which reduces the high frequency portion in the frequency spectrum.
    The perforated cover may be a sheet which is provided with a large number of small holes. The degree of perforation is of the order of 1 to 10% maximum of the total area of the covering, in particular in the range of 1 to 3%. Each individual pore has an area in the range between 0.02 and 2 mm 2, preferably in the range of 0.04 to 1 mm 2.
    The perforated cover is usually welded to the wall of the exhaust gas conductive component. This results in a reliable attachment with the desired high service life. However, it has been found that high loads can act on the perforated cover when thermal expansions occur.
    The greater the difference in the thermal expansion coefficients of the components, the more the charges of the perforated covering have a critical effect. An example for different thermal expansions are, for example, on the one hand ferritic steel alloys as it is possible to use for the exhaust gas conducting components, and on the other hand the austenitic steel alloys which are used for the perforated cover.
    The object of the invention is to develop the known component so that no problem occurs during thermal expansion of the component and / or recovery.
    To achieve this object, a support is provided according to the invention by means of which the perforated covering is mounted on the wall of the component, a clearance being provided between the support and the covering so that the covering can move parallel to the wall. component. The invention is based on the basic idea of attaching the perforated cover to the component such that heat expansions and displacements relative to the resulting support and component wall are admitted. The perforated cover is here mounted on the component with a kind of sliding fit.
    The support is preferably a frame which is mounted on the wall and surrounds the outer edge of the cover. The perforated cover is thus mounted on the component reliably in all directions.
    To limit the maximum possible displacement of the perforated cover reliably in all directions, a clearance is preferably provided between a front face of the cover and an abutment surface of the opposite support remote from the end face. Even if the presence of the game on one side of the cover is sufficient, a game is ideally present in all directions to allow the expansion of the cover in all directions.
    According to one embodiment of the invention, the support has a mounting section which is mounted on the wall, and a retention section for the covering which, seen in a direction perpendicular to the wall, is offset with respect to the section of retained, the abutment surface being formed by a step at the transition of the mounting section to the retaining section. In this embodiment, the cover is fixed between the wall and a surface of the mounting section facing the wall. The support can thus be made to a layer.
    The support is preferably a stamped sheet component. This allows the manufacture of the support with little effort and inexpensively.
    The mounting section may be welded to the wall of the exhaust gas conductive component. Several spot welds may be sufficient for this. It is also possible to provide the connection of the mounting section to the wall by means of a circumferential weld. This weld then preferably extends circumferentially along the outer edge of the support.
    It is preferably provided that the cover is maintained prestressed between the mounting section and the wall. The preload prevents on the one hand an uncontrolled back and forth movement of the overlap between opposed abutment surfaces within the predetermined clearance. This could lead to premature wear due to the relative movement between the cover and the wall or support that then occurs. Prestressing also ensures that the perforated cover can not vibrate with respect to the component and the support; this would cause unwanted noises.
    The prestress can be obtained in that the perforated cover, in the initial state, that is to say when it is not yet tightened between the wall of the component and the support, has a shape which is different from the shape of the wall. In a simple case, the perforated cover is flat while it is intended for closing an orifice in the wall of a pipe. The prestressing may also be obtained in that only the edge region of the perforated cover is deformed plastically and for example provided with a molding, or is folded.
    According to an alternative configuration, it provides that the support is made double layer at least in sections. In this embodiment, the perforated cover is fully received in the holder so as to obtain a pre-assembled assembly which can then be mounted on the component.
    It is preferably provided that the support, seen in section, has a U-shaped cross-section and that the covering is received between the two branches of the support so that the abutment surface is formed by the inner face of the folding section between the two branches. Such a bending piece can be manufactured reliably at reduced manufacturing costs. This is particularly valid when the support is a folded sheet component.
    It is preferably provided an elastic prestressing of the two branches against each other and against the overlap arranged between them. Vibration noises due to undesired relative movement between the perforated cover and the support are thus reliably avoided.
    According to a configuration of the invention, it is expected that the support is welded to the wall at the level of the folding section between the two branches. This area is very well accessible to arrange a weld. The weld can then be provided only in sections or also so as to be entirely circumferential.
    According to one embodiment of the invention, it is provided that the covering is fixed integrally to the support at a point. This can be done for example by spot welding. The point fixing of the cover to the support serves as a kind of fixed bearing from which the perforated cover can expand and contract.
    According to one embodiment of the invention, it is provided that the support has a wall thickness of less than 1 mm, in particular a wall thickness of about 0.8 mm. It has been found that it is also possible to fix the perforated cover reliably with such thin supports.
    The covering may have a wall thickness of the order of 0.3 mm. Such a thin sheet has proved to be already mechanically strong enough. A small wall thickness also facilitates the introduction of perforations.
    According to one configuration, it is provided that the wall and the covering are made of materials having different respective thermal expansions. The wall can then be made of a ferritic steel alloy and the covering made of an alloy resistant to corrosion by hot gases and wet corrosion, in particular of a ferritic alloy or an alloy of austenitic steel. This results in low manufacturing costs for the exhaust gas conductive component, while high corrosion resistance results in recovery.
    It is preferably provided that the support is also made of a ferritic steel alloy. This also leads to reduced manufacturing costs.
    In the following, the invention is described using two embodiments which are shown in the accompanying drawings. These show: Figure 1 schematically a part of an exhaust system with two exhaust gas conductive components, Figure 2 a component with a cover mounted thereon in a sectional view, the FIG. 3 shows the component of FIG. 2 in an exploded perspective view, FIG. 4 the component of FIG. 2 in a perspective top view, FIG. 5 enlarged a support with a covering before mounting on the component, the FIG. 6 is an exploded view of the assembly of FIG. 5, FIG. 7 the component of FIG. 2 in a perspective sectional view, FIG. 8 a detail of FIG. 7, FIG. 9, a gas conductive component of FIG. Figure 10 shows part of Figure 9 in an enlarged view, and Figure 11 schematically a sheet blank for the support used in the second embodiment.
    Figure 1 shows different components of an exhaust system. This is a first exhaust pipe 1, a housing 2 and a second exhaust pipe 3.
    Pipes 1 and 3 serve to guide exhaust from an internal combustion engine to the environment. Components may be arranged in the housing 2, by means of which the exhaust gas is treated, for example a catalyst substrate or a particulate filter. The housing 2 can also be the housing of a silencer.
    When the components 1, 2, 3 are arranged at a distance from the exhaust valves of the internal combustion machine and the temperature of the exhaust gas has thus already slightly decreased, a ferritic steel alloy can be used as material for components 1,2,3.
    In the embodiment shown, the components 2, 3 are provided with an orifice 10. This may for example be circular, rectangular, polygonal or oval and have an area of several square centimeters. An overlap which is attached to the component by means of a support is respectively associated with the orifice 10. This is explained in detail below.
    Figures 2 to 8 show a first embodiment. A perforated cover 12 is used therein, which in general terms is fixed against the wall of the component 3 by a support 14.
    Although the exemplary embodiment of the first embodiment relates to a cover 12 closing an orifice 10 in an exhaust gas-conducting pipe, it is clear that the port 10 can also be provided at another location in the exhaust pipe. installation of exhaust gas. The orifice 10 may be provided in the enveloping surface of the housing of component 2, as shown in FIG. 1, or in one of the end walls of component 2.
    The perforated cover 12 is composed of a metal sheet or a metal sheet whose wall thickness may for example be 0.3 mm. It is provided with a large number of small perforations, the portion of the perforations in the total area of the covering being in the range of 1 to 10% and preferably 1 to 3%.
    The perforations may have a circular shape, a rectangular shape or another geometry. When their open surface is converted into a circular shape, it corresponds to a diameter of the orifice of the order of 1 mm to 1.5 mm.
    When the dimensions of the orifices are less than these values, it is also referred to as a microperforated covering.
    An alloy resistant to corrosion by hot gases and wet corrosion, for example Inconel, is used as the material for the coating 12. It is preferably possible to use an alloy of austenitic steel or a suitable ferritic alloy. The wall thickness of the covering is less than 1 mm and in particular of the order of 0.5 mm.
    These values are valid for the initial sheet. With regard to chip removal or chip removal processes such as can be used for the manufacture of the cover, the cover may be "thicker" after machining when the distance of the surface area are measured, as burrs may form.
    The support 14 is in the form of a frame and consists of a sheet. A ferritic steel alloy is preferably used as a material, preferably a steel alloy having the same thermal expansion behavior as the component or wall of the component with which it is connected.
    The support 14 has a circumferential mounting section 16 which is adapted to be fitted to the wall of the component 3. A retaining section 18 is provided inside the circumferential mounting section 16. The retaining section 18 forms the inner edge of the support 14 and defines a recess which is slightly greater than the orifice 10.
    As is particularly visible in Figure 8, the retaining section 18 is offset from the mounting section in a direction perpendicular to the mounting section 16 and thus also perpendicular to the wall of the component 3. The offset corresponds at least to The thickness of the perforated cover 12. The offset is preferably slightly larger (see in particular FIG. 2).
    The offset between the retaining section 18 and the mounting section 16 can be obtained by appropriate stamping of a flat sheet blank of the support.
    The retaining section 18 defines a housing for the covering 12 which can be arranged in this housing (see in particular FIGS. 3, 5 and 6). The dimensions of the cover 12 are then chosen so that the cover is slightly smaller than the housing. In other words, a small clearance remains between the front faces of the cover 12 and a step 20 formed at the transition between the retaining section 18 and the mounting section 16. This set s is in the range of 0 , 2 to 4 mm.
    When the support 14 is mounted on the component 3, the perforated cover 12, because of the game, can "migrate" below the retaining section 18 parallel to the wall of the component 3, more precisely until it abuts respectively against the step 20 which serves as an abutment surface on the support for the covering 12.
    The support 14 is integrally mounted on the wall of the component 3 by means of its mounting section 16. In the exemplary embodiment shown, the mounting section 16 may be welded by several spot welding locations 22 (see FIG. Figure 4). It is also possible to use a weld 24 surrounding the mounting section 16 on the outside (see Figure 2).
    The support 14 can either be pre-folded on the component 3 (see FIG. 3) or alternatively also be placed on the component in a plane state (see FIG. 5) and then be pressed against the component 3 so as to follow the outline of component 3. It is then welded.
    As can be seen in FIG. 8, there is provided an attachment point 26 at which the cover 12 is fixed to the retaining section 18. Here it may be a spot welding spot. The attachment point 26 determines the position of the perforated cover 24 with respect to the support 14 at this point, so that the cover 12 expands or contracts from this location as temperature changes occur. A pre-assembled assembly is thus furthermore formed.
    The cover 12 is elastically resiliently received between the outer surface of the wall of the component 3 and the face of the retaining section 18 facing the component 3. For this purpose, it is possible to pre-fold the cover or to emboss a molding along the outer edge of the cover. Alternatively, as shown in Figure 2, it is possible to fold an outer edge 28 of the cover 12 so that the overlap 12 is made double layer in the area of its outer edge. The desired resilient prestressing is here produced due to the restoring forces of the folded edge section.
    The spring preload is on the one hand so high that unwanted vibration noises by a movement of the cover 12 with respect to the component 3 and the support 14 are prevented. The spring forces are on the other hand so weak that a relative movement of the covering 12 with respect to the component 3 and the support 14 due to the temperatures is possible without excessively high mechanical loads acting on the covering 12.
    Figures 9 to 11 show a second embodiment. The same reference numerals are used for the known components of the first embodiment. On this point, it is referred to the explanations above.
    The difference between the first and the second embodiment is that in the second embodiment, the support 14 is made in two layers. Viewed in cross section perpendicular to an outer edge of the support 14, it has a cross section U (see Figure 10), the cover 12 being arranged between the two opposite inner faces of the two branches 14A, 14B. The inner side of the fold point between the two arms 14A, 14B acts here as abutment surface 20.
    The support 14 may be made from a sheet metal blank 14 'as shown in FIG.
    In the second embodiment, the cover 12 is, in the same way as in the first embodiment, slightly smaller than the housing formed inside the support 14 so that a clearance remains between the front faces. the cover 12 and the abutment surface 20.
    An elastic prestress acts between a cover 12 and the support 14 also in the second embodiment. This can be generated here in that the two branches 14A, 14B of the support 14 receive between them the cover 12 in the manner of a spring clamp. In addition, or alternatively, it may be provided that the outer edge of the cover 12 is folded as is known from the first embodiment.
    The support 14 can form together with the cover 12 a pre-assembled assembly which is fixed to the component 3. For this purpose, it is possible to use a weld 24 which connects the support 14 to the wall of the component 3 in the area of the folding point between the two branches 14A, 14B. The weld 24 can then be provided circumferentially or only in sections.
    Alternatively, it is possible first of all to weld the sheet blank 14 'of the support 14 to the component 3, for example by several spot welds 22, then to place the cover 12 on it and then to bend the outer legs of such so that the support 14 is made double layer.
    In the second embodiment, it is also possible to provide an attachment of the cover 12 relative to the support 14 at a point of attachment, in particular by a spot welding spot.
