Definitions
- the present invention relates to an exhaust gas purification device for an internal combustion engine Motor vehicle, comprising a housing and at least one at least with interposition of a resilient bearing element, essentially cylindrical exhaust gas purification body, the Housing a tubular bearing section and two includes transition cones connected to this end and at least one is essentially vertical is divided to the longitudinal axis extending plane, wherein the bearing section at least partially in the direction designed to expand conically at the division level and is between the at least one Emission control body and the bearing portion of the housing existing, at least partially from the bearing element filled annulus at least partially in Direction extended to the division level.
- Flue gas cleaning devices are under others from DE 4322062 C1 and JP 1-280614 A known. Furthermore deal with exhaust gas purification devices in tubular construction and in particular their production is EP 0681095 A1 and EP 0703354 A1.
- a generic exhaust gas purification device in pipe construction is known from DE 2331434 A1.
- This emission control device differs from the further State of the art recognized above, in particular by that the tubular bearing portion of the housing not according to the shape of the exhaust gas purification body is cylindrical, but rather - at least in some areas - conical towards the division level extended. Accordingly, between the at least one emission control body and the latter surrounding bearing section of the housing existing annular space not over the axial extent of the exhaust gas purification body the same cross section; rather expanded that annulus - at least in some areas - in Direction to the division level.
- This exhaust gas cleaning device proves to be disadvantageous that the strong over the axial length changing thickness of the bearing element to locally considerably leads to different holding forces. By the corresponding different pressure ratios there are tensions within the exhaust gas cleaning body, that can shorten its lifespan.
- the object of the present invention is accordingly based on an exhaust gas purification device of the beginning to create the type mentioned, which is sufficient at a safe storage of tolerant exhaust gas cleaning bodies in the housing and at low manufacturing costs through as uniform as possible on the exhaust gas cleaning body acting holding forces distinguished.
- this object is achieved solved that two flue gas cleaning body axially offset from each other Exhaust gas purification body ring-shaped surrounding bearing elements are provided, which are different before their assembly have radial extension, the tubular bearing section for each exhaust gas purifier body two storage areas that expand conically in the same direction has between which the housing extends substantially cylindrical.
- Each of those two annular bearing elements of each exhaust gas purification body is therefore an own flared Storage area of the housing assigned between those the housing extends substantially cylindrical.
- the radial extension of the ring-shaped bearing elements is expedient to the respective different mean width of the between the (ideal) Exhaust gas purifier and the existing annulus customized. In this way, about the individual annular bearing elements have the same holding forces apply to the respective exhaust gas cleaning body.
- the present invention allows the simplest Way a compensation of the different due to tolerance Dimensions of the individual exhaust gas cleaning bodies in such a way that the annular bearing elements depending on the actual dimensions of each Exhaust gas cleaning body positioned differently become.
- the bearing elements - With such exhaust gas purifiers, whose dimensions deviate upwards from the nominal dimension, the bearing elements - compared to their arrangement at nominal size of the exhaust gas purifier - depending on the extent of the actual deviation in dimensions from the nominal size more or less towards the Division level shifted; be reversed in such Emission control bodies, the dimensions of which Deviate nominal size downwards, the bearing elements - opposite their position at the nominal size of the exhaust gas cleaning body - depending on the extent of the actual deviation of nominal size more or less from the division level away into the tapered annulus postponed.
- the invention relates to housings whose tubular bearing section has an elliptical, oval, polygonal or other suitable Has cross-section. Furthermore it should be clarified that the transition cones within the scope of the present invention equally symmetrical and asymmetrical can be trained.
- the opening angle of the conical areas of the bearing section depends in particular on the type of used bearing elements as well as the surface roughness the inner wall of the housing and the outer surface of the exhaust gas purification body.
- Components is a double taper angle between 3 ° and 8 ° particularly favorable.
- the present invention is equally suitable for catalytic emission control devices such as for Soot filter.
- the respective exhaust gas purification device may comprise one, two or more exhaust gas purification bodies.
- the present invention is both applicable to such emission control devices, at which the transition cones independent, only later with components that are joined together in the bearing section, as well as on such exhaust gas purification devices which at least one transition cone integrally with the adjacent area of the bearing section is connected and merges into them.
- the at least one division level can thus be in the area the transition of the tubular bearing section to one Transition cone run. This is particularly the case with exhaust gas purification devices with only one exhaust gas purifier a reasonable arrangement of the division level; however, a corresponding structure of the housing can be as will be explained in more detail below, with advantage also for exhaust gas cleaning devices with two exhaust gas cleaning bodies use.
- the division level can, however, if two flue gas cleaning bodies are to be stored in the housing are, also by the bearing section of the housing run through.
- Source mats used are in the direction of the fiber course only stretch to a small extent or compressible.
- emission control bodies have emission control bodies a series like the one above results in strong deviations with regard to tolerance their circumferential dimensions.
- the storage mat or each individual annular bearing element at least two axially adjacent strips, the joints of the two strips offset from one another are. In this way, simple means prevent that with exhaust gas purifiers with the largest dimension in the area of the joint of the storage mat or annular bearing element forms a continuous gap, through the exhaust gas on the exhaust gas purification body can flow past.
- Another preferred development of the invention is characterized in that the bearing element from a at least once, but preferably several times built around the exhaust gas purification cord is.
- the bearing element from a at least once, but preferably several times built around the exhaust gas purification cord is.
- wrapping the exhaust gas cleaning body several times education is also reliable with a cord one of the flow around the exhaust gas purification body Prevents axial gap.
- the cord will thereby from the division level in the ring-shaped Gap between the exhaust gas purification body and the bearing section of the housing introduced and in layers by means of one pushed over the exhaust gas purification body Assembly rings compressed.
- the diameter of the cord is in the way on the dimensions of the components matched the exhaust gas purification device that yourself with an exhaust gas purifier Smallest the cord in the tapered ring Cavity wedged and thus can be compressed.
- Assembly and compression ring which in this case Assembly of the exhaust gas cleaning device is used, expediently has a feed channel for the Cord on which is used for the condensing Front of the ring opens. This makes possible the successive feeding of further cord, which in several Windings around the catalyst body and is compressed.
- the annular described above Bearing elements or the one explained above Cord can be controlled by force axial insertion of the bearing elements in the tapered radial gap between the emission control body and bearing section of the housing the desired Set the holding force very precisely.
- Each takes the bearing element regardless of the actual Dimensions of the exhaust gas cleaning body at the same axial insertion force such a position that gives the same radial contact pressure.
- the bearing element in the annular Cavity are injected while the exhaust gas purifier body already in its final position it may be useful the surface of which previously reduced the roughness To undergo treatment, for example to coat.
- the one for the axial insertion or pressing in of the bearing element pressure ring used expediently has on the end face an elastomer ring that fits accordingly the narrowing clear width of the ring-shaped Gap between the emission control body and the housing can deform. This prevents the bearing element damaged when pressed into the annular cavity becomes.
- the same result can be used alternatively thereby achieve that the pressure ring has several segments which includes a relative movement to each other can execute that the outer dimensions of the Pressure ring on the changing inner diameter of the Can customize housing.
- the design of the Pressure ring with a pneumatically or hydraulically inflatable Ring pillow has the same effect.
- the exhaust gas purification device shown in Fig. 1 comprises an exhaust gas purification body 1, which by means of two essentially annular arranged at the end Bearing elements 2 stored in a housing 3 is.
- the housing includes a tubular bearing section 4 for the exhaust gas purification body 1 and two adjoining the bearing section at the end Transition cones 5. These end in nozzle 6 for Connection of an exhaust pipe.
- the housing 3 is approximately in the center transverse to the longitudinal axis 7 divided.
- the division level divides the storage section 4 thus in two halves, in an overlap area 8 nested and by means of a fillet weld 9 are interconnected.
- the central division of the housing allows that each of the two transition cones 5 in one piece with the adjacent half of the bearing section 4 manufactured is and passes into it.
- the tubular bearing section is in his central area is cylindrical.
- the two outer areas 10 of the bearing section 4 taper conically towards the transition cones 5 too, or in other words, they're in Tapering towards the division level educated. Accordingly, the Area of the two conical bearing areas 10 of the between the housing 3 and the exhaust gas purification body 1 each existing annular space 11 in the direction of Division level.
- the exhaust gas purification device shown in Fig. 2 differs essentially by the following features of the exhaust gas purification device 1: Instead of two axially offset the exhaust gas cleaning body is an annular bearing element 1 in the housing 3 by means of a storage mat 12 stored, the axial extent of about 50% the axial length of the exhaust gas purification body 1 is. Furthermore, the case is not in the essentially divided in the middle; the division level is rather in the area of transition one of the two Transition cones 5 to the bearing section 4. Overlapped here one molded onto the corresponding transition cone cylindrical collar 13 is also cylindrical End area 14, in which the conical bearing area 10 of the bearing section 4 of the housing runs out. The two parts are by means of a fillet weld 9 of the housing firmly connected.
- the storage mat 12 can, for compensation Tolerance-related deviations in the dimensions of the Emission control body 1 of the nominal size in which the annulus widening conically towards the division level 11 different positions (see double arrow B).
- a two exhaust gas purifying body Emission control device can be manufactured by that the right transition cone through an assembly is replaced, which is essentially mirror-symmetrical is built up to the remaining rest of the exhaust gas purification device.
- the exhaust gas purification device shown in Fig. 3 differs from that according to FIG. 2 in essentially only in that the exhaust gas purification body 1 not with a single storage mat is stored in the housing, but rather by means of two axially spaced annular bearing elements 2.
- the bearing section of the housing has two axially spaced conical bearing areas on, between which the housing is cylindrical. According to the different radial width of the two conically widening annular spaces 11 'and 11 ′′ have the two corresponding annular ones Bearing elements 2 'and 2' 'prior to assembly different radial extension. To this Way is an approximation of the two ring-shaped Bearing elements on the exhaust gas purification body transferred holding forces to each other possible.
- Annulus can be filled with insulation as is known as such.
- Fig. 4 illustrates another way, a Exhaust gas purification device comprising two exhaust gas cleaning bodies according to the present invention build.
- 1 to 3 are extensive Comments on the structure of this exhaust gas purification device dispensable. You can see the case assembled from three components, namely one in essentially mirror-symmetrical, too tubular conically widening on both sides Bearing section 4 and two ends of this welded-on transition cones 5. Can be seen of course possible, according to FIG. 4 from three parts assemble assembled housing from four parts, by providing a division in the middle.
- Exhaust gas purifiers apply that manufacture can be done in different ways. Either becomes the emission control body to be installed in each case initially measured, and at least one bearing element is on the peripheral surface of the exhaust gas purification body depending on its actual size more or less far from a middle position staggered, whereupon the Unit consisting of exhaust gas cleaning body and around this lying around bearing element (lying around Bearing elements) from the division level of the housing forth - essentially steered - in its Bearing section is inserted until the exhaust gas purification body reached its final position Has.
- Another possibility for assembly is in that the exhaust gas purifier in its final position within the housing , whereupon the at least one Bearing element in the conically tapered annular space between the emission control body and the housing is introduced; through a force controlled Pressing the bearing element takes this in dependence from the actual dimension of the respective exhaust gas cleaning body automatically that position which ensures a predetermined holding force.
- This The method is particularly suitable if the at least one bearing element by multiple Wrapping the emission control body with a compacted cord is produced.
- a combined procedure at which the respective emission control body in the housing is inserted, but not in its final position, but rather first in an assembly position which is opposite the end position towards the division level is offset.
- the bearing element is then force-controlled brought into the annulus and pre-compressed, wherein the bearing element with an initial contact pressure pressed against the exhaust gas purification body becomes. Finally, exhaust gas purifiers and Storage element together in the housing in the direction moved towards its conical taper until the exhaust gas cleaning body its final position occupies. This gives the bearing element its final preload.
- FIG. 5 schematically illustrates the structure of a Bearing element made of two axially abutting, the (schematically indicated) exhaust gas cleaning body 1 almost completely surrounding strip 15.
- the Bumps 16 of the two strips depending on which from the actual dimension of the exhaust gas cleaning body 1 forms a more or less wide gap offset against each other. A flow around the exhaust gas purification body is excluded in this way.
- Fig. 6 shows an assembly and compression ring, such as he in the context of the above Process in which the bearing element from a put several times around the exhaust gas purification body Cord is built up, can be used.
- the assembly and Compression ring 17 has a feed channel 18 for the cord 19 on.
- With the front edge 20 of the Assembly and compression ring 19 is in the Cord introduced in the annulus force-controlled condensed so that they widen to the conically widening adapts clear cross-section of the annulus.
