Bearing member for supporting an exhaust element,

Storage system comprising a plurality of bearing elements and

Exhaust system consisting of storage system and exhaust element

The invention relates to a bearing member for supporting an exhaust element having a circumference U within an exhaust passage, wherein the bearing element is formed flat and has a length Lu, and has a width Bh, wherein the length Lu in a direction Ru runs and the length Lu in a Rh direction extends so that the direction of Ru or the length Lu is parallel to the circumference U of the exhaust element alignable.

There is already a bearing mat of length L and the width B for supporting an exhaust element from the DE 297 09 180 Ul known. The mounting mat is constructed in several parts and comprises four with respect to the length L arranged side by side and connected across the width B sections with different intumescent properties. The length L corresponds to a circumference U of the exhaust element and the width B of a height H of the exhaust element. Alternatively, a bearing mat is described, comprising three with respect to the width B of juxtaposed cuts, each of which has the length L.

From WO 2005/106222 Al is formed of four sections, multilayer bearing mat of length L and width B, also for supporting an exhaust element is known. The width B corresponds to a height H of the exhaust element. Although However, two auxiliary members have the width B, but a significantly smaller length L and increased intumescent property. These are spaced from one another between the first portion and the second portion being sandwiched, so that they in the areas - -

chen high curvature are positioned on the exhaust element. The accompanying the intumescent auxiliary parts pressure increase is not critical in these areas of high curvature. The length L of the auxiliary parts is smaller than the width B of the auxiliary parts.

From DE 197 14 851 Cl two strip-shaped, arranged in longitudinally spaced bearing elements for an exhaust element are known.

In JP 200240440 A one bearing mat is described which has two hook-shaped ends for attachment or preload in peripheral direction, which engage in one another. The elasticity of the bias voltage is achieved by a mäanderähnliches intermediate piece.

The object of the invention is based is to design a mounting mat in such a manner and to arrange that an optimal use of material is ensured in consideration of various physical properties of the mat as well as optimum support of the exhaust element.

The object is achieved according to the invention in that at least two webs and a joint extending in the direction of Ru transverse web of the length Lu are provided, whereby the transverse web with respect to the direction of Rh is arranged offset to the respective web and connects the webs on one side with one another. By the formation of webs which are arranged distributed over the length Lu of the bearing member and each extending across the width of Bh of the bearing member, can be stored optimally exhaust element with simultaneous saving of material for the bearing element. The webs can be distributed over a circumference U of the exhaust element and can - the width of Bh of the bearing member on - via at least a part of a - -

extending height H of the exhaust element. The transverse web is arranged offset to the respective web, and thus can also be adjacent to the respective web, may be placed with or without spacing from the respective web. The length Lu of the cross piece preferably corresponds to the circumference U of the exhaust element, so that this element is at the exhaust gas sealing manner over the entire circumference U.

The inventively provided transverse web, which connects the various webs together, ensures a sufficient fixing or positioning of the webs relative to each other. The webs and the transverse web are brought directly against the exhaust element to the plant.

The bearing element is preferably formed as a mat with a ceramic and / or metallic Gewebenetz- and / or fiber structure. The bearing element may be mono- or multilayer construction, wherein the respective bars and the associated transverse web are respectively arranged in a single layer.

Advantageously, this may be when a rectangular-shaped basic form G and at least two webs and the transverse web forming recesses are provided, whereby the lands and recesses with respect to the direction Ru are arranged side by side. By using a rectangular shaped bearing element can be a casing or enclosure of the exhaust element, regardless of shape, can be ensured. The length Lu of the bearing element corresponds to the circumference U of the exhaust element, wherein the width is Bh of the bearing element is equal to or smaller than the height H of the exhaust element. The recesses according to the invention result in addition to the already mentioned advantage of saving material that the bars spaced from one another and thus over the circumference U of the exhaust element - -

be distributed.

Within the single layer construction of the bearing element of the crossbar and the respective webs are arranged substantially side by side. In the areas where the webs are connected to the transverse web, and in particular may be an overlap of the transverse web may be provided with the respective web, using various materials for the transverse web and the webs for connection thereof.

Further, it may be advantageous when the bearing member is formed single-layered, wherein the webs and / or the transverse web of the same or different materials are formed. Due to the inventive multi-part design of the bearing element comprising a plurality of webs and the webs connecting transverse web, optimum storage can be ensured even when using a single-layer bearing element by appropriate design of the webs or the transverse web or by using appropriate materials for the webs and the transverse web , When multiple mat-like usually bearing elements are arranged one above the other, then such a storage system could be described as multiple layers.

Advantageously, it may also be, if three webs are provided which are arranged with respect to the length Lu of equal or unevenly distributed, wherein the respective web width bl, b2, b3 and having the width bl, b2, b3 of the various webs equal or of different sizes formed. Depending on the type of material used for the respective web, in particular with regard to the functional properties of the web, so the sealing, support and / or insulating function of the respective web can have a desired width bl, independent of the - -

Width b2 b3 of the other webs, can be chosen. The same applies for the distances between the webs and the size of the recesses provided therein.

It may be advantageously provided that the cross-web and / or at least one web is constructed as a sealing, support and / or insulating means. The bearing member may come a sealing, support and / or insulating function, depending on in which area of ​​the exhaust element, the bearing element is used. The insulating effect thereby includes an insulating effect to prevent heat losses, a damping effect for the reduction of the sound outlet and, in general, a shield for reduction of the exhaust gas emanating from the radiation element.

Since the transverse web preferably extends over the entire circumference U of the exhaust element, the sealing function comes to this, so that no gas can flow past the exhaust element. In principle the transverse web fulfilled when used as a sealant in a way, the support function and the storage function for the gas element, at least in the region in which the exhaust gas element is received from the transverse web. Regardless of the material of the transverse web is as sealants also have an insulating function. However, the essential support function could be associated with the webs, as they can stretch H of the exhaust gas element over the greater part of the height and distributed around the circumference U a statistically determined support of the exhaust element can provide. Due to the webs provided between the recesses, a sealing function against flowing through the exhaust gas can not be attributed to the webs as a whole. However, for each web to a local isolation function. By selecting the width bl of the respective web and the distance between the Ah - -

Webs can be varied in particular, this support and insulation function as desired and adjusted.

Of particular importance may be for the present invention if the cross web is formed as a sealing and supporting means and at least one web is designed as a support means. Since the transverse web has a relatively small area ratio, its insulating effect is minor nature. The same applies to the ridges, so that the transverse web substantially the sealing and support function belongs, while the webs belongs to the support function in addition to the local isolation function substantially.

The respective function is an appropriate material composition based on selected by the user from the on the market bearing mats.

The object is also solved by a storage system LS consisting of a bearing element, wherein one end connected to the first bearing element second bearing element is provided, which is arranged next to the first bearing element. The achievable with a bearing member function separation can be varied according to the use of a bearing system LS with at least one second bearing element. For example, an additional sealing effect and / or a supporting effect could be associated with a transverse web of the second bearing element also, while the webs of the second bearing member may be only one insulating effect can be optionally limited, granted on insulation or damping and / or radiation protection. The use of two or more storage elements allows the complete enclosure of the exhaust element without recesses.

Advantageously, it may also be when the first bearing member and the second bearing element with respect to the direction of Rh - -

are arranged with a distance a. Thus, the storage system LS and a width Bg at the height H of the exhaust member by relative displacement of the bearing elements can be adjusted. formed in this adaptation or gaps relative displacement between the bearing elements, because the webs do not fully engage in the recesses.

It may be advantageous if the second bearing element comprises a plurality of connected via a transverse web webs, the webs of the first bearing element are at least partially arranged in a recess of the second bearing element and at least partially arranged, the webs of the second bearing element in a recess of the first bearing element are. Both bearing elements have a substantially similar basic form G. Due to the existing mirror symmetry or point symmetry of the basic form of G both bearing elements can be placed into one another in the manner of a puzzle. This provides a rechteckför- Miges storage system LS can be prepared in particular, which can be placed mantelför- mig to an exhaust element. The storage system LS thus formed has with regard to the different webs on the one hand and the various cross-members on the other hand as well as the materials used for the various webs and transverse webs any and extent adjustable bearing, sealing and insulation properties, as described, advancing for the bearing element.

In addition, it may be advantageous if at least one web has at least one undercut or a thickening or at least one undercut or a thickening is provided in the region of at least one web, wherein the respective bulge is disposed inside a corresponding undercut. By the undercut and the corresponding thickening slipping of the two bearing elements is prevented relative to each other not only in the direction Ru, thus in the circumferential direction but in particular in the direction of Rh, that is, in the axial direction with respect to the exhaust element.

Further, it may be advantageous if the first bearing element is at least partially formed erosion resistant than the second bearing element. In principle, all bearing elements are designed as a sealing, support and / or insulating means. All bearing elements perform the same functions as a rule. Alternatively or additionally, it may be provided that only one bearing element improved erosion properties, is thus formed from material which is resistant to erosion caused by exhaust gas. This material is expensive and must be used only for a bearing element. Basically it is also possible that only the first bearing element is at least partially formed as a sealing and support means and the second bearing element is at least partially formed only as a support and / or insulating means. The sealing and insulation function would be separated.

But functional differences between the bearing elements or parts of the bearing elements are possible. The sealing function can only be associated with the first bearing element or the transverse web of the first bearing element while the ridges of the first bearing element and the entire second bearing element have a substantially support and / or insulating function. With regard to the materials to be selected as well as their costs and taking into account the material properties of a corresponding bearing system can desirably be constructed or broken. The warehouse- - -

System preferably has a rectangular shape with the length and the width Lu Bh.

It may be advantageous if the first bearing member and the second bearing element are of the same basic form G and at least partially into each other are used. Due to the same geometry, a more efficient use of material for the creation of the respective bearing element is ensured. The bearing members can be stamped out of rectangular strips or webs of the respective material in a simple way and assembled in specified manner.

The object is also achieved by an exhaust system AS consisting of at least a bearing element or a bearing system LS, and a received therein exhaust member, said exhaust element has a height H and having a circumference U and the length Lu corresponds to U the circumference. The exhaust element is disposed within the bearing element or bearing system LS or surrounded by the latter. The various webs or transverse webs meet the desired function as previously performed.

Advantageously, this may be, when the width of Bh and / or the width Bg at most between 30% and 90%, preferably 70% of the height H. By far shortened construction of the bearing element or the bearing system LS, a further reduction of the material used can be carried out in addition to the recesses provided.

Ultimately, it may be of advantage if the webs at the same over the circumference U, or are arranged unevenly distributed. By a symmetrical distribution of the webs over the circumference U a symmetrical mounting of the exhaust gas element is ensured. In that regard, the installation position of Abgaselemen- _ _

tes and the exhaust system AS not be considered.

It may also be advantageous if the transverse web of the first bearing element and / or the transverse web of the second bearing element is at least partially designed as a sealant. Since the cross-web is applied over the entire circumference of the exhaust member around it, the sealing function comes into substantially. Additionally or redundant, the cross web of the second bearing element can thereby be used as a seal.

Furthermore, it may be advantageous if at least one web of the first bearing element and / or at least one web of the second bearing element is at least partially designed as a support and / or insulating means. As previously already described the function of the different webs with regard to the desired type of storage or isolation can be selected.

The object is also solved by an exhaust system AS comprising a first bearing element and at least one second bearing element as well as an exhaust element having a circumference U, and a height H, wherein the exhaust member is sheathed for storage in an exhaust passage with the respective bearing element, said bearing element as mat is formed and a corresponding circumferentially U length Lu and in a direction Rh has a width Bh, wherein the length Lu is in a direction Ru, which is aligned parallel to the circumference U of the exhaust member, said first bearing member and the second bearing element are arranged with respect to the direction of Rh or without spacing to each other with a distance Ah, where Ah is the distance that is a maximum of 2.5 times the width Bh or a maximum of 20% to 40% of the height H. Thus, despite multi-part and spaced _

Formation of the bearing elements tion a sufficiently close storage or guaranteed support of the exhaust element that establishes the durability of the exhaust system AS. The respective bearing element lies directly against the exhaust element and is preferably arranged in the region of the respective end face of the exhaust element. The respective bearing element may be present also one or more layers and / or one or more parts formed, it does not depend on a distance of the parts within a bearing element. Thus, an exhaust element to be stored sufficiently despite significant reduction in the area of ​​the bearing elements and, despite considerable saving of mat material. The unoccupied space of the thus-mounted exhaust element can be used for other heat insulation and / or heat recovery systems. The mat comprises a ceramic and / or metallic Gewebenetz- and / or fibrous structure having flexible properties for storage of a sintered exhaust element within an exhaust duct of metal. There may also be three, four or more bearing elements provided at a corresponding distance Ah, wherein, in the case of a distance greater than zero, also at different distances Ah between the bearing elements are possible.

In order to ensure an optimal storage of the exhaust system AS within the exhaust duct that is concerning calibrated prior to the introduction of the exhaust system AS its diameter to the required minimum. The measure is determined by the size or the diameter of the exhaust gas to be stored element plus the thickness of the bearing element or the bearing system used used LS.

It is advantageous for this purpose also, that the first bearing element and / or the second bearing element has a width Bh between 20 mm and 100 mm, or between 30 mm and 50 mm. - -

The width of Bh of the bearing member is, in principle according to the size of the desired bearing surface, which is also dependent on the height H of the exhaust element. Narrow bearing elements ensure the greatest material savings on the one hand and the largest open spaces in the exhaust element on the other.

It is advantageous for this purpose and that the width of a maximum of between 1% and 50%, or at most between 10% and 30% of the height Bh is the first bearing element and / or the second bearing element H of the exhaust element. In particular, in exhaust members having a large height H of the proportional width can vary Bh of the bearing elements is very low.
