Definitions
- the invention relates to a catalyst housing according to the preamble of claim 1.
- Catalytic converter housing as used to connect a catalytic converter in exhaust systems from Internal combustion engines, in particular motor vehicles, are used, are available in a variety of designs, with two systems prevailing on the market to have.
- the first system one with a catalytically active material coated monolith (ceramic or metallic design) with an inflatable mat wrapped, which has the task of storing the monolith.
- this inflatable mat again put a sheet metal jacket, which is wound with a fixed force and this keeps the monolith in place.
- This tense sheet metal jacket is to the End faces stapled, which ensures a tight fit of the monolith.
- Face Inlet and outlet funnels are installed that meet the requirements (Connection of the exhaust pipe) are aligned.
- the inflatable mat becomes an organic liquid submerged to make it easier to assemble.
- This organic liquid evaporates then, so that the inflatable mat becomes very porous.
- the thermal stress on the converter the converter shells in contrast to that Monoliths very different, so that for a safe function of the Shell converter a production with very tight tolerances is necessary.
- Such catalyst housing arrangements are known for example from DE 42 23 648 C, DE 38 21 397 C, DE 38 11 224 C and DE 37 29 994 A.
- the funnel that has the task of Differences in diameter between the inlet or outlet tube and the catalyst body to compensate should on the one hand ensure a controlled exhaust gas flow and on the other hand Protect the inflatable mat from being washed out by the pulsating exhaust gas flow.
- the funnel collar is usually placed in a 90 ° angle to the funnel axis, as is the case for example from DE 34 30 398 A, Figure 5 is known.
- Such funnels are usually made from sheet metal by deep drawing, however, there are two disadvantages. On the one hand you need sheet metal boards with a high thickness in order to make a still weldable small diameter for the Obtain connection of the exhaust pipe.
- the second disadvantage is the 90 ° funnel adjustment to the funnel collar, which is welded to the catalytic converter housing. It can happen that depending on the location of the monolith in its Tolerance field and possible decentralized fastening of the funnel collar to the An effective monolith surface of up to 15% is covered.
- a Improvement here shows the funnel connection according to FIG. 1 of DE 34 30 398 A, in which there is only a slight overlap of the effective monolith face. This However, connection requires high precision in the manufacture of the housing parts and the Funnel, since otherwise it is not possible to insert the funnel into the housing with a precise fit.
- the object of the present invention is to provide a catalyst housing with a low weight and on the other hand to produce with a favorable exhaust gas flow.
- the invention therefore uses the basic concept of the introduction described first Catalytic converter housing, in which the housing jacket is not formed in one piece with the funnel is.
- the inlet and / or outlet funnel of the catalyst housing a so-called tube funnel is used instead of a deep-drawn funnel. That is, the The blank geometry of the funnel is a tube. The pipe is placed in a follow-on tool required large diameter expanded and the required small diameter moved in. The tube is preferably pulled in by pressing (Pulling) the tube funnel into a die.
- the tube funnel is manufactured in two stages, whereby the widening of one end takes place on the retraction or vice versa. Because of this It is possible to process the blank (semi-finished product) with the thickness just required provided, which is necessary for the expansion.
- the funnel has on its large diameter a material thickness that is at most 90% of the material thickness on its small diameter. Especially the material thickness at the large diameter is at most 80%. That is advantageous Material thickness on the large diameter, however, at least 40% and in particular at least 60% of the material thickness on the small diameter, otherwise the funnel will close again becomes difficult and on the other hand the weldability either on the large diameter or on the Small diameter becomes problematic.
- this thickness distribution on the funnel it is possible, weight optimized on the one hand and easy to weld on the other To design both ends, so that on the one hand the separate catalyst jacket without problems on the large diameter of the funnel and the separate exhaust pipe on the Small diameter of the funnel can be welded.
- the hoppers of the prior art have an opposite Weight distribution, d. H. the large diameter has a thicker wall thickness than that Small diameter, which makes these funnels much heavier.
- connection slope is off manufacturing reasons preferably directed inwards.
- The is manufactured Connection slope advantageous due to rolling.
- connection slope is advantageously kept as short as possible, i. H. so, that within the allowable manufacturing tolerances for the middle section and the funnel seamless connection of the two parts is possible.
- connection slope is advantageous at an angle of 10 ° to 70 ° and in particular from 20 ° to 50 ° to the longitudinal axis, since under this geometry, larger manufacturing tolerances with short connection bevels possible are.
- connection bevel The part that crosses the connection bevel can also be provided with a connection bevel be formed, which is then directed opposite (to the outside).
- connection slope advantageously has an angle to the longitudinal axis ⁇ the angle of the internal bevel.
- ceramic or metallic are preferably used as the catalyst core
- Monoliths are used, with one or more monoliths in the middle part of the Catalyst housing can be accommodated.
- the tubular middle part in which the catalyst core is located is very particularly preferred located, wound, d. H. is - as described at the beginning - from a sheet metal strip manufactured, which the catalyst core (with a the catalyst core against the middle part supporting intermediate layer, especially mat) wrapped.
- the funnel described above is preferably inlet and arranged on the outlet side of the middle part.
- FIG. 1 shows the winding converter 20 which is common today and which is constructed from a middle part 21 and an inlet funnel 22 and an outlet funnel 23
- Sheet metal jacket 21 encloses a catalytically coated monolith 24 below Intermediate layer of an inflatable mat 25.
- the catalytically coated monolith 24 wrapped with the inflatable mat 25 which has the task of storing the monolith 24.
- On the Inflatable mat 25 is then placed on the sheet metal jacket 21 and with a predetermined force wrapped (pulled) over the inflatable mat. This will tension the unit.
- the tense Sheet metal jacket 21 is then stapled on its end faces, whereby a tight fit of the Monolith 24 is guaranteed.
- sheet metal blanks are deep-drawn Funnels 22, 23 attached to the end faces of the sheet metal jacket 21 and welded 26.
- Zum Compensation of tolerances have the funnels 22, 23 funnel bundles 27, 28 which in one 90 ° to the longitudinal axis.
- the funnel bundles result from Deep drawing the funnels 20 to 23 from the corresponding sheet metal plates by clamping the edge of the board.
- the funnel edge 27 or 28 accordingly has the greatest material thickness of the funnel 22 or 23, since there is almost no pulling of the material here.
- This thickness exceeds the thickness of the Small diameter 29 or 30, since the starting thickness of the sheet metal plate can be chosen in this way must that the small diameter after deep drawing a still weldable thickness for the Have joining and welding with the inlet or outlet pipe (not shown).
- the wall thickness during deep drawing the large diameter is equal to the blank wall thickness (the sheet metal plate).
- the wall thickness is far below due to the deformation the blank wall thickness. But since there is also a welded joint on no diameter a minimum wall thickness is required here.
- This certain minimal Wall thickness can only be influenced by changes in the blank dimensions, so that the raw part wall thickness and thus the part weight for production must be increased, although it is not necessary for the connection to the middle section.
- funnel setting 27 or 28 which means that it depends radial position of the monolith 24 in its tolerance field a concealment 31 of up to 15% the cross-sectional area F of the monolith 24 can come.
- the pipe funnels 2 and 3 avoid the connection problems to the sheet metal jacket 1 with a new connection geometry.
- the sheet metal jacket 1 is on its ends 11 and 12 at an angle of approx. 30 ° to the horizontal (longitudinal axis) inclined so that there are connection bevels.
- On these connecting slopes 11 or 12 are diameter tolerances of the wound sheet metal jacket 1 compared to Large diameters 7 and 8 of the tube funnels 2 and 3 compensated. This allows the Large diameter 7 or 8 axially parallel to the connection bevels 11 or 12 be welded on.
- the connecting slopes 11 and 12 cover the Inflatable mat 5, so that they are not washed out by the pulsating exhaust gas flow can.
- the channels 13 of the catalyst core are not covered 4, so that its effective cross section can be fully used.
- funnels 2 and 3 can be performed asymmetrically.
- the tubular blank preferably first drawn into a die at one end and then, to produce the large diameter, asymmetrical to the longitudinal axis of the Small diameter widened.
