Definitions
- the invention relates to a holder of a honeycomb body in a housing, in particular in a housing of an exhaust system of an internal combustion engine, according to the preamble of claim 1.
- a honeycomb body are used in particular in automotive engineering to clean an internal combustion engine generated exhaust gas used.
- Such a holder is known for example from US 4,948,353 and from US 5,079,210. Also from a similar holder is known from JP 8-294 632.
- the honeycomb body is made of smooth and corrugated sheets and is surrounded by a cylindrical jacket.
- the coat has its circumference distributed slots, which emanate from an end face of the jacket.
- the honeycomb body with the jacket is aligned so that the slots during the cleaning process of the exhaust gas facing away from the exhaust gas inlet side are.
- the honeycomb body is connected to the jacket only in the area of the slots.
- honeycomb body in particular radially shrinks near its end faces. You can do this in the connection area Tensions occur between the honeycomb body and the jacket, the one make permanent connection of the honeycomb body to the jacket difficult.
- Honeycomb body made of very thin sheets for example thinner than 0.03 mm or even as 0.025 mm, assume a barrel-like shape, with the middle Area retains its original diameter, but the end faces have a smaller diameter Have diameter.
- honeycomb bodies according to the features of the claim 1 solved Further advantageous details of the holder according to the invention Honeycomb bodies are described in the dependent claims.
- a honeycomb body is in one by means of an inner jacket tube Housing held, in particular a housing of an exhaust system of an internal combustion engine, the inner jacket tube axially one of two edges has limited overall length, which is significantly smaller than the axial length of the Honeycomb body, with the inner jacket tube approximately axially centered around the Honeycomb body arranged and with this in at least one axial section technically connected, in particular soldered.
- the inner jacket tube is in a portion within the axial section in which it is inside with the honeycomb body (1) is connected, or directly adjacent to this also on the outside or fixed in the housing (2), the not with the housing (2), but after Areas of the inner jacket tube connected to the inside of the honeycomb body (1) (7) are designed as radially elastic spring elements (18).
- the invention Bracket is characterized in that the spring elements of the deformation of the honeycomb body without tearing away, and at the same time the Connection of the inner jacket tube to the housing takes place in the area in which the diameter of the honeycomb body changes only slightly.
- a shorter length of the inner jacket tube compared to the honeycomb body has the Advantage that particularly strongly shrinking areas of the honeycomb body (such as Example near the end faces) are not hindered in their movement. additionally a heat-insulating gap is formed around these areas, in particular the heating behavior of the honeycomb body is positively influenced, since the one introduced on the face side Thermal energy in these areas not to a surrounding of the honeycomb body Inner jacket pipe can be derived.
- the spring elements can preferably be formed by slots and in the circumferential direction be limited, which, depending on their dimensions, is almost a can adjust any elasticity.
- honeycomb bodies made of very thin sheets in exhaust systems from Motor vehicles have surprisingly been shown in tests that this considerable not only on the gas inlet side, but also on the gas outlet side Subject to deformation loads. While heating a the honeycomb body is primarily caused by an exhaust gas via the exhaust gas inlet side, the honeycomb body cools down simultaneously from both ends. this leads to to an increased radial shrinkage of the honeycomb body near the end faces towards other areas.
- the inner jacket tube forms in connection with the slits out segments that behave similar to spiral springs. The means that these spiral springs, when they are in contact with the honeycomb body, the thermal expansion or shrinkage of the honeycomb body can follow at least radially. This can cause thermal stresses between honeycomb body and inner jacket tube can be significantly reduced. thats why a formation of spring elements on both sides very advantageous.
- the entire honeycomb body is with a holder arranged approximately symmetrically to a central plane. So the inner jacket tube constructed essentially symmetrically, which in particular the assembly such a bracket is simplified. In addition, this corresponds to symmetrical arrangement of the substantially symmetrical deformation of the Honeycomb body during cooling.
- the slots have at least one end region, one slot width and one Slot length and at least partially limit a spring element of the inner jacket tube such that the spring element is at least radially deflectable. This ensures a reduction in the thermally induced voltages, which due to a different thermal expansion behavior of the inner jacket tube and honeycomb bodies can arise. It is particularly advantageous that the slot width is at least 1 mm, preferably at least 2 mm is. This ensures that the spring elements are even stronger Do not adversely affect internal deformation.
- the Slot width over the slot length can be from an end area increasing towards the slot.
- the slots can extend at least partially in the circumferential direction of the inner jacket tube. This means that the slots are not exclusively straight are, but have, for example, a corrugated or sinusoidal shape can.
- the slots in the at least one End area have a recess.
- the recesses are designed so that the formation of notches in the end region of the slots is prevented.
- Spring elements each have at least one transverse slot.
- the cross slot runs thereby essentially parallel to the edge of the inner casing tube.
- the cross slots serve to set a certain bending stiffness of the spring element. A larger number and / or a greater length result in Cross slots in a spring element, which results in a lower bending stiffness radial deflection already occurs due to lower forces.
- the transverse slots in at least one end section to be rounded with a notch due to high dynamic stress is avoided.
- the honeycomb body has sheet metal layers on, which are structured so that these can flow through for an exhaust gas exhibit.
- the honeycomb body has in particular at least one channel density of 800 cpsi ("cells per square inch").
- the sheet layers are with sheets executed, the sheet thickness preferably less than 0.03 mm, in particular less than 0.025 mm.
- Such a honeycomb body is suitable due to its surface area, which is very large in relation to the volume, is very good as a carrier body for a catalytically active coating. This ensures that a catalytic active surface flowing past exhaust gas Is provided, which means the implementation of pollutants in the exhaust gas is particularly effective.
- the small sheet thicknesses preferably less than 0.025 mm, have a very low surface-specific heat capacity. This has As a result, the honeycomb body quickly reaches a temperature after a cold start achieved which for a catalytic conversion of the pollutants in the exhaust gas is needed.
- connection of the inner casing tube to the housing can be done in different ways Way done, which is explained in more detail with reference to the drawing. Important is that the inner jacket tube can not come loose, the connection between Housing and inner jacket tube, however, not the elasticity of the inner jacket tube outside of the area in which the connection to the housing takes place.
- FIG. 1 shows an exemplary embodiment of a honeycomb body 1 according to the invention in a housing 2 of an exhaust system 3 (not shown) of an internal combustion engine 4 (not shown).
- the honeycomb body is coaxial in the housing 1 and an inner jacket tube 7 arranged.
- the inner jacket tube 7 essentially has axial 5 slots 6 and has a total length 9, which of two Edges 8 is axially limited.
- the central axis 5 indicates that the honeycomb body in the generally rotationally symmetrical or with an oval or elliptical cross section are designed.
- the inner jacket tube 7 is on its outside in at least one compared to its total length 9 axially smaller section 10 (hatched) directly or indirectly connected to the housing 2.
- the honeycomb body 1 has one axial honeycomb body length 11, which is limited by the end faces 29.
- the honeycomb body 1 is in the connection area 19 (dotted) with the inside of the Inner jacket tube 7 connected. Not with the housing 2, but with the honeycomb body 1 connected areas of the inner jacket tube 7 are as radially elastic Spring elements 18 designed. This allows an almost unimpeded expansion or shrinkage of the honeycomb body 1 during alternating thermal loads.
- the spring elements 18 are delimited by slots 6, which are preferably are arranged symmetrically to a central plane 14 of the inner casing tube 7. This supports the essentially symmetrical shrinkage of the Honeycomb body 1 under operating conditions that ultimately result in a barrel-like Form leads in which the middle area changes little.
- the slots 6 are arranged outside the central plane 14 and extend in this embodiment up to the edges 8 of the inner casing tube 7th
- Figure 2 shows schematically the structure of an internal combustion engine 4 an exhaust system 3.
- the exhaust gas generated in the internal combustion engine 4 is passed through the exhaust system into the environment.
- the exhaust system 3 components for cleaning the exhaust gas are arranged.
- Figure 2 shows an example of a honeycomb body through an inner jacket tube 7 is held with slots 6 in the housing 2.
- Figures 3 to 8 show different mounting options between the inner jacket tube 7 and housing 2. There are very different mounting options applicable, which have in common that they have the elasticity of the inner jacket tube 7 not significantly impair in the off-center area.
- Fig. 3 shows a positive connection, in which via an intermediate piece 13 Inner jacket tube 7 is held in a bead 12 of the housing 2. To avoid a swelling mat 20 or a material such as Mica be introduced as an intermediate layer.
- Fig. 4 shows another type of positive connection, which at the same time radial sliding seat 12, 13 forms the radial, but no axial displacements allows.
- a swelling mat 20 or mica can be used as an intermediate layer be used.
- FIG. 5 shows a particularly simple and preferred embodiment, in which the inner jacket tube 7 directly in a correspondingly shaped outer bead 12 of the housing 2 is held, again with the possibility of an intermediate layer 12 to provide mica or the like. a bracket without an intermediate layer 20 is however possible.
- Fig. 6 shows a holder, in which the inner casing tube 7 via a Rohrahnntiches Intermediate piece 13 is suspended on the housing 2
- This intermediate piece 13 can be soldered or welded on. It can also be different from axial Slits separate segments (not shown) exist, which is an additional one The elasticity of the attachment causes.
- Fig. 7 shows an embodiment similar to Fig. 6, but with the inner jacket tube 7 is deformed in an S-shaped cross section, so that it is also an intermediate piece 13 forms which is attached to the housing 2.
- FIG. 8 shows a schematic side view with a longitudinally sectioned housing 2 particularly preferred embodiment of the invention.
- the inner jacket tube 7 provided with axial slots 6, which are approximately symmetrical to a center arranged annular intermediate piece 13 lie.
- these slots go not quite up to the edges 8 of the inner jacket tube 7. This can be at Production process because of the smooth edges 8 easier to handle than one to slotted inner jacket tube at the edges.
- the connection area 19 (dotted) between inner jacket tube 7 and honeycomb body 1 ends at about half the length of the Slots 6, so that elastic spring elements 18 even when not continuous Slots 6 arise.
- the annular intermediate piece 13 can also be so stiff be made that at thermal tensions between honeycomb body 1 and Housing 2 essentially evades the housing 2 slightly.
- Figure 9 shows schematically a cross section through a honeycomb body 1 and Inner jacket tube 7, the cross section through a region of the inner jacket tube 7 is arranged which has no slots 6.
- the honeycomb body 1 has Sheet metal layers 25, which are structured so that an exhaust gas can flow through them Form channels 26.
- the channels are here by stacking corrugated and smooth Sheets formed.
- the honeycomb body 1 is then swallowed or Winches of the sheet layers 25 produced.
- the honeycomb body preferably has one Impact density of at least 800 cpsi.
- the sheets 25 have a sheet thickness 28, which is preferably less than 0.025 mm.
- the holder of a honeycomb body according to the invention is guaranteed in a housing permanent fixation of the honeycomb body, especially in an exhaust system an internal combustion engine.
- the temperature differences that occur and pressure fluctuations can by the bracket according to the invention can be compensated for by the radial expansion or shrinkage of the honeycomb body are not so hampered that life-limiting Tensions arise between the housing and the honeycomb body.
