Definitions

• the invention relates to a flat gasket, in particular an exhaust gas side seal for an internal combustion engine.
• EP 0 955 489 B1 describes a metal gasket having various surface pressure areas including first, second and third metal plates, the first and second metal plates having beaded areas and the third metal plate having the first and second metal plates crimping an inner metal plate Area is in operative connection.
• JP 02286859 A discloses a cylinder head gasket which has locking elements for receiving inserts in the region of media through-holes.
• the invention has for its object to provide a gasket, in particular an exhaust-side gasket for an internal combustion engine, in which by optimizing the materials used on the one hand, a price reduction compared to conventional gaskets is achieved and on the other hand, a simpler structural design should be given.
• This object is achieved by a flat gasket, in particular an exhaust-side gasket for an internal combustion engine, formed by a at least single-layer provided with a recess sealing element, consisting of a high-quality, in particular a very temperature-resistant, metallic material and a sealing element receiving support member made of a lower quality metallic material wherein the carrier element receives the sealing element in such a way and leads that the sealing element is fixable and mountable.
• a kind of hybrid solution is thus provided, consisting of two different materials, with only the higher temperatures exposed, relatively narrow sealing area is formed by a sealing element of very high-quality temperature-resistant material.
• a sheet of much cheaper material can be used, which only serves to realize the main installation thicknesses, if necessary, to connect a plurality of sealing elements together and make the entire seal assembled and fixable.
• connection of the sealing element and the carrier element is advantageously achieved on a mechanical basis by clamping.
• a flat gasket according to the invention can be used advantageously as an exhaust flange gasket.
• a method for producing the flat gasket is proposed by an at least one-layer sealing element predetermined contour is punched out that a single support element or a plurality of elements which are connected to a support member, are punched out, wherein the support member has a perforation that sealing element side of the Carrier element, or the elements, noses are punched out that lugs are at least partially expanded, that the sealing element is placed on each of the lugs, and that further lugs are deformed back to form a snap connection in the direction of the sealing element.
• the type of mechanical connection is easy to manufacture and can be manufactured using common technologies on the market.
• the noses can act by appropriate compression as additional sealant. These can be used, for example, for micro-sealing, if a material is used as a carrier sheet, which is soft enough and can flow accordingly.
• the lugs can also serve as stopper elements, provided that the material of the support plate is solid or stiff enough. Another advantage of the clamping with such noses is that the heat conduction or the heat transfer can be adjusted by the number and shape of the noses. As a result, very different materials with very different temperature ranges can be combined.
• Suitable materials for the sealing element are in particular Ni-Cr-Fe alloys, wherein other temperature-resistant alloys can be used.
• the support member may be made of a commercially available steel, for. B. cold strip exist.
• FIGS 1 and 2 basic structure of the invention consisting of carrier element and sealing element flat gasket;
• FIG. 6 shows an alternative embodiment of FIGS. 1 and 2.
• FIGS. 1 and 2 show alternative embodiments of the flat gasket 1 according to the invention which can be used as an exhaust flange gasket.
• the same components are provided with the same reference numbers.
• a support element 2 for example consisting of cold strip, which is provided with a hole 3.
• a sealing element 4 comprising a recess 4 ', guided and connected via only hinted, formed out of the support member 2, lugs 5 mechanically connected to the support member 2 in the manner of a snap connection.
• the lugs 5 are widened in the opposite direction, so that some of them are positioned above and below the sealing element 4.
• the sealing element 4 consists in this example of a temperature-resistant Ni-Fe-Cr alloy and is guided within the perforation 3 of the support element 2, such that it is easy to fix and assemble.
• FIGS. 3 and 4 show sections through connection variants between carrier element 2 and sealing element 4.
• the widened lugs 5 and the free leg 6 of the sealing element 4, which initially rests on the lower lugs 5 of the carrier element 2, are shown in the upper image.
• the lower image of Figures 3 and 4 shows the state in which the upper lugs 5 were deformed back and thus the leg 6 drove between them and hold in the clamped position.
• the sealing element 4 is provided outside the free leg 6 with a beaded area 7.
• Both the carrier element 2 and the Dichtelment 4 are punched out of suitable plate-like precursors, wherein the perforation 3 of the carrier element 2 corresponds to the outer contour of the used reaching sealing element 2. Lochungs furnish beyond the noses 5 are punched out and expanded in the opposite direction.
• the sealing element 2 is placed on individual lower lugs 5 and finally the upper lugs 5 deformed back in the direction of the sealing element 2, so that they - as shown in Figures 3 and 4 - rest on the free leg 6 of the sealing element 4.
• Figure 5 shows an alternative to the figures 3 and 4 embodiment.
• material protrusions are formed axially outside the leg 6 by the lugs.
• Figure 5 shows an embodiment in which the lugs 5 of the support member 2 and the sealing member 4 are provided in a plane, that is, that lugs 5 are inserted in radial recesses 8 of the sealing element 4.
• Figure 6 shows an alternative to the figures 1 and 2 embodiment of a flat gasket 9.
• the carrier element 10 includes a perforation 12, while the sealing element 11 is provided with a recess 11 '.
• the perforation 12 and the recess 11 ' are congruent. Since the sealing element 11 is not positioned with respect to the figures 1 and 2 within the given there perforation of the support element, a different type of connection must be brought here.
• the sealing element 11 is in aligned form, that is positioned co-centrically to the perforation 12.
