Abstract

The invention relates to a system for fixing a catalyst support assembly (1) in a housing (2). Said catalyst support assembly (1) comprises a cladding pipe (3) and a honeycomb structure, through which an exhaust gas permeates (4). The cladding pipe (3) has at least a first (5) and a second convex section (6) comprising flanks (15) and is connected to the honeycomb structure (4) at least in one part (7). The housing (2) has at least a first (8) and second recess (9) with lateral faces (16). The system is characterised in that the convex sections (5, 6) extend partially into the recesses (8, 9) in such a way that a fixed mounting (20) and at least one floating mounting (21) with axial (10) play (11) are formed. Said system guarantees that the catalyst support is permanently fixed, in particular during the structural vibrations that occur in the exhaust system of an internal combustion engine.

Description

  • The present invention relates to an arrangement for fixing a catalyst carrier body in a housing according to the preamble of claim 1. Such catalyst carrier bodies are used, for example, in exhaust systems of internal combustion engines, in particular in automobile construction.
  • Such an arrangement is known for example from EP 0 212 243. In this document, a holder for a metallic catalytic converter carrier body in a jacket tube is proposed. The catalyst carrier body is embedded or attached in such a way that thermal elongation is not hindered. The holder is designed with two or more spacers, as a result of which the catalyst carrier body is held within the casing tube at a distance of a few millimeters. Only one spacer is firmly connected to both the catalyst carrier body and the jacket tube. In this way it is prevented that due to the different thermal expansion behavior of the casing tube and the catalyst carrier body, stresses occur which can negatively influence the service life of such a holder.
  • Studies have shown that tremendous body vibrations occur in the adjacent exhaust system during the operation of engines used in automobile construction. These essentially result from the explosive and time-controlled combustion processes of the fuel-air mixture in the engine. Very large acceleration forces occur in particular in the individual components of the exhaust system, which can endanger the life of a holder of a catalyst carrier body in an exhaust system.
  • Proceeding from this, it is an object of the present invention to provide an arrangement for fixing a catalyst carrier body in a housing, which is particularly suitable for ensuring a long residence time of the catalyst carrier body in a housing at a predeterminable point, in particular a transmission of in one Exhaust system occurring body vibrations is damped on the catalyst carrier body.
  • To achieve this object, an arrangement with the features of claim 1 is proposed. Further advantageous configurations are specified in the dependent claims.
  • The arrangement according to the invention for fixing a catalyst carrier body in a housing comprises a catalyst carrier body with a jacket tube and with a honeycomb body through which an exhaust gas can flow. Such catalyst carrier bodies are used in particular for cleaning an exhaust gas or for the catalytic conversion of pollutants in the internal combustion engine which are present in the exhaust gas. The honeycomb body is connected, in particular soldered, to the casing tube at least in a partial area. The jacket tube has at least a first and a second bulge with flank surfaces. The housing has at least a first and a second recess with side faces. The arrangement according to the invention is characterized in that the bulges extend at least partially into the depressions in such a way that a fixed bearing and at least one floating bearing are formed with an axial bearing play. The fixed bearing ensures permanent fixation of the catalyst carrier body in the housing. Due to its axial bearing play, the floating bearing allows the catalyst carrier body to expand, which occurs due to the temperature increases in the catalyst carrier body.
  • According to an advantageous embodiment, the at least first and / or second bulge are axially circumferential. This has the consequence that a uniform storage over the circumference of the jacket tube is guaranteed.
  • According to a further embodiment, the flank surfaces of the bulges and the outer surface of the tubular casing each enclose an outside angle.
  • The outside angle of the fixed bearing is smaller than the outside angle of the floating bearing. The outside angle of the fixed bearing is preferably in the range from 90 ° to 110 °. In this way, high axial forces can also be absorbed via the fixed bearing, such as occur, for example, due to body vibrations and pulsation in the exhaust gas flow.
  • According to yet another embodiment, the housing has an inner surface, the side surfaces of the depressions and the inner surface of the housing each enclosing an inner angle and the inner angle of the fixed bearing being smaller than the inner angle of the floating bearing. In this way, the side surfaces of the depressions corresponding to the flank surfaces of the bulges are provided, so that the largest possible form fit is ensured between the bulge and the depression. This enables good structure-borne noise damping, in particular in the case of the fixed bearing, and good radial guidance, if appropriate, in the case of the floating bearing.
  • It is particularly advantageous that the inside angle is at most 5 ° larger than the outside angle of the fixed bearing. The inside angle is preferably the same size as the outside angle of the fixed bearing. An equal size of the inner angle and the outer angle has the advantage that the flank surfaces and the side surfaces are arranged parallel to one another. This enables a particularly stable embodiment of a fixed or floating bearing.
  • According to yet another embodiment, the depressions have a depth and the bulges have a height, the depth being at least 2 mm greater than the height. This also allows a radial thermal expansion of the catalyst carrier body, whereby the occurrence of thermal stresses in the bearing is prevented.
  • According to an advantageous further development, the flank surfaces of the bulges lie against the side surfaces of the depressions, at least in the fixed bearing. In particular, a flat contact area is formed. The direct system has a particularly damping effect on structure-borne noise, with the resulting acceleration forces only being reduced to a greatly reduced extent the housing to the catalyst carrier body. This enables a particularly long-lasting fixation of the catalyst carrier body in the exhaust system.
  • According to yet another embodiment, a filling material is arranged at least in the at least one floating bearing between the flank surfaces of the bulges and the side surfaces of the depressions. It is preferably a material that is temperature-resistant and suitable for use in an exhaust system. Such a filling material, such as mica, allows thermal expansion of the catalyst carrier body, the thermal expansion behavior of the filling material being adapted such that thermally generated gaps or cavities between the casing tube and the housing are closed by the filling material. This ensures an exact fixation in the storage.
  • It is particularly advantageous if the catalyst carrier body is essentially surrounded by the filler material. The result of this is that the entire catalyst carrier body is mounted with little vibration because the filler material significantly reduces a transition of the acceleration forces from the housing to the catalyst carrier body.
  • According to a further embodiment, a circumferential cavity is formed between the bulges of the casing tube and the honeycomb body, in which a heat-insulating medium, in particular air, is preferably arranged. In this way, the bulges have a further function in addition to the storage of the catalyst carrier body. The cavity prevents heat flow from the honeycomb body to the tubular casing, which improves the light-off behavior of the honeycomb body. This allows earlier catalytic conversion of pollutants in an exhaust gas flowing through the honeycomb body.
  • According to a further embodiment, the bulge of the fixed bearing has a first axial length of 1 to 20 mm, the bulge of the floating bearing preferably having a second axial length of 10 to 30 mm. The first axial length can For example, be made smaller because the inside and outside angles of the fixed bearing are made smaller than that of the floating bearing. If the bulge of the fixed bearing is designed as a sheet metal arranged in the form of a collar, the first axial length can be limited to a few millimeters. Basically, the floating bearing only has the task of providing radial guidance and ensuring thermal expansion in the axial direction. The bearing play required for this must therefore also be taken into account when designing the axial second length.
  • According to a particularly advantageous development, exhaust gas flows through the honeycomb body in a preferred direction of flow, the fixed bearing being arranged downstream of the floating bearing. The hottest area of the honeycomb body is usually located near the entry side. The result of this is that the thermal expansions also occur to an increased extent in this area. An arrangement of the floating bearing in this area allows these thermal expansions, which prevents lifelong stresses.
  • According to yet another embodiment, the housing is made in two parts with half-shells, these half-shells being joined, in particular welded, with a longitudinal seam. The design of a housing with two half-shells supports, for example, the arrangement of filler material around the catalyst carrier body during assembly, in order to enable the catalyst carrier body to be decoupled from the body vibrations of the housing.
  • Further advantages and particularly preferred embodiments of the arrangement according to the invention for fixing a catalyst carrier body in a housing are described with reference to the following drawings. Show:

  • FIG. 1 shows schematically and in a section an embodiment of an arrangement according to the invention for fixing a catalyst carrier body 1 in a housing 2 is. The casing tube 3 is connected to the honeycomb body 4 in a partial region 7, preferably soldered. The casing tube 3 has a first 5 and a second bulge 6. Correspondingly, the housing 2 has a first 8 and a second recess 9. The bulges 5 and 6 extend into the recesses 8 and 9 in such a way that a fixed bearing 20 and a floating bearing 21 are formed with an axial bearing play 11. The first 5 and the second bulge 6 are axially circumferential 10. The floating bearing 21 is arranged upstream 14 of the fixed bearing 20. The catalyst carrier body 1 is additionally surrounded by a filler 25. Such a fixation of the catalyst carrier body 1 in the housing 2 has the advantage that a transition of body vibrations from the housing 2 to the catalyst carrier body 1 is prevented.
  • The first bulge 5 of the tubular casing 3 has a cavity 28 which surrounds the honeycomb body 4 and in which a heat-insulating medium is arranged. This cavity 28 prevents heat transfer from the honeycomb body 4 to the casing tube 3, which ensures faster heating of the honeycomb body 4 and thus also earlier catalytic conversion of pollutants in the exhaust gas. The second bulge 6 is designed as a kind of collar, which was welded onto the casing tube 3. On the one hand, this ensures a continuous connection of the casing tube 3 to the honeycomb body 4 in the partial region 7 and also allows the first axial length 30 (not shown) of the fixed bearing 20 to be made relatively small.
  • FIG. 2 shows an end view of an embodiment of a honeycomb body 4 with a casing tube 3. The honeycomb body 4 has sheet metal layers 12 which are structured in such a way that an exhaust gas can flow through them. The sheet metal layers 12 comprise smooth 32 and corrugated sheets 33, so that channels 13 through which exhaust gas can flow are formed. The sheet metal layers 12 were layered or stacked and then looped or wound, whereby the honeycomb body 4 is formed.
  • FIG. 3 schematically shows a detailed view of a bulge 5, 6 of the casing tube 3 with a corresponding depression 8, 9 of the housing 2. The casing tube 3 has a casing surface 17 which enclose an outside angle 18 with the flank surfaces 15 of the bulge 5, 6. In addition, the bulge 5, 6 has a height 24 starting from the lateral surface 17. The bulge 5, 6 extends at least partially into a corresponding depression 8, 9.
  • The depressions 8 and 9 have two preferably circumferential side surfaces 16 which enclose an inner angle 19 with the inner surface 22 of the housing 2. A symmetrical structure of the depressions 8 and 9 or bulges 5 and 6 is not necessary, but reduces the manufacturing effort. The depth 23 of the depression 8, 9 is preferably at least 2 mm greater than the height 24 of the bulge 5, 6.
  • FIG. 4 shows, in perspective and schematically, a further embodiment of an arrangement according to the invention for fixing a catalyst carrier body 1 in a housing 2. The housing 2 is designed with two half-shells 26 which, after the catalyst carrier body 1 has been arranged in the interior of the housing 2, on two Longitudinal seams 27 are connected to each other. The half-shells 26 are preferably welded to the longitudinal seams 27. The housing 2 consisting of the half-shells 26 also has depressions 8 and 9, which correspond to the bulges 5 and 6 of the tubular casing 3 of the catalyst carrier body 1. This configuration of the housing 2 with two half-shells 26 is particularly suitable for the arrangement of filler material 25 (not shown) which surrounds the catalyst carrier body 1 and a forwarding prevented from body vibrations of the housing 2 on the casing tube 3. The filling material 25 is arranged so that the end face of the honeycomb body 4 is not reduced.
  • The arrangement according to the invention ensures permanent fixation of the catalyst carrier body, in particular in the event of body vibrations of the exhaust system of an internal combustion engine, which can be advantageously used in particular in the case of honeycomb bodies made of very thin metal foils with a thickness of less than 30 μm.
