These all devices are prefabricated unit, and these prefabricated units are combined in the exhaust of vehicleIn branch road, and (exhaust is clean between the entrance of exhaust branch road and outlet, to form accommodating internalsChange plug-in unit, muffler, TEG module etc.) container. In order to produce for accommodating inside, between entrance and outlet, there is obvious cross section sudden change in the chamber of member. The circle of this deviceCylindricality external shell can be manufactured in a different manner. For example, in the time of catalyst converter or particulate filter, instituteThe plug-in unit of meaning utilizes sheet material to wrap, and makes plug-in unit be held and be positioned at by the mounting mat of plantingIn housing, wherein, exhaust stream crosses this plug-in unit and this plug-in unit is made up of pottery conventionally. In addition, alsoHave two external shells that housing component is made that taken the shape of the letter U by cross section, plug-in unit and mounting mat are pressed from both sidesBe held between these two housing components, and in the time that external shell is closed, these two housing components are movedMove and reach together following degree:, the longitudinal edge of these two housing components is overlapping, and these are longitudinalEdge is subsequently by melting welding or soldering.
From US2001/0055551A1, know a kind of method for the manufacture of catalyst converter, wherein,Extending beyond two sheet metal parts of 360 ° around plug-in unit separately reels mutually. These two sheetsMetal parts forms external shell subsequently.
DE102004042078A1 has described a kind of side for the manufacture of air discharge guide device housingMethod, wherein, external shell by partly overlapping and in overlapping region interconnected three orMore sheet metal bars form. The shape of cross section of this housing is not columniform, but comprisesThe part that amount of curvature does not wait. Overlapping region is positioned at the part that curvature is less.
Summary of the invention
The object of the invention is to invent a kind of device that can be easy to the external shell of manufacturing that comprises,Wherein, this external shell can and be lightweight with low cost fabrication. In addition, also proposed onePlant the improved method for the manufacture of this device.
Air discharge guide device for vehicle according to the present invention has columniform external shell, shouldColumniform external shell comprises external shell part and is arranged in the inside of external shell partInner shell part. This external shell part forms the portion of the external shell larger than inner shell part circumferencePoint, or as selecting, also can form the part of the exterior periphery equally large with inner shell part.The radial outside of inner shell part is attached to external shell part, specifically combines. This is outerPortion's housing component extends c-shaped or extends into closed annular in cross section. External shell part andInner shell part is independent part, and is connected to each other subsequently.
Because external shell part mainly absorbs load, and this external shell part is due in cross sectionC-shaped or circlewise closed mode extend and enclose internal part and almost form external shellThe whole periphery of body, is therefore also the very equal of external shell according to the feature of device of the present inventionThe uniform clamping of even load and internal part. This is and the basis of previous housing component solutionMatter difference, in previous housing component solution, single housing part has the cross section of U-shaped,Do not point to towards each other the longitudinal edge of inner side. In addition formation external shell in the present invention,Two independent housing components (parts of separating in essence) can be by than in the prior artThree or more similar housing components are more easily connected to each other. Inner shell part is positioned at external shellIn the region of body part, be, inner shell part is closed in this external shell part, and protectionThis region.
Preferably, the longitudinal edge of external shell part extends in the mode not overlapping each other. According to thisEmbodiment, do not rolled thus according to device of the present invention and outside its longitudinal edge is overlappingPortion's housing. This rolling can cause following truth: the inner longitudinal edge distance of advancing during rollingFrom very long, this makes to apply shearing force on the adjacent part of inside, and adjacent component is for example pacifiedDress pad. When sealing is during according to the external shell of device of the present invention, relative motion can spread over twoIn side, spread in the region of two longitudinal edges of inner shell part.
Housing component is bending extension stably on cross section preferably, do not have the ladder of sudden changeDeng, as utilized U-shaped housing component recurrent feelings in the region of longitudinal edge in prior artCondition is such. Therefore this has reduced manufacturing cost and has ensured the uniform pliability of this external shell,To be the meetings such as ladder strengthen unilateral external shell reason.
External shell part and inner shell part are preferably made up of sheet metal.
External shell part and the curvature of inner shell part in overlapping region should be to be suitable for each other, inner shell part is resting on external shell part completely to its radially outer.
According to preferred embodiment, along the circumferential direction each interval of the longitudinal edge of external shell partOpen, and the gap producing between longitudinal edge is closed at internal side diameter by inner shell part. Therefore,Aspect stressed, the inner shell part of preferred embodiment mainly has should in external shell partIt is the task that this very little gap closes. The existence in this gap has advantages of following important.When external shell is used for clamping internal part or when being closely resting on internal part, totalIt is the cross section tolerance issues that has internal part (for example inserting catalyst converter or particulate filter).Due to the independent manufacture of external shell, its adjustment is suitable for treating to the internal part of combination, therefore outsideDuring the manufacture of portion's housing, by being applied to, power on external shell part, make the external shell part can be byClosely be pressed against on internal part separately, and make it be suitable for this internal part, thereby obtainThe optimal cross-section shape of external shell. Due to the existence in this gap, get rid of following situations:In the less situation of the cross section of internal part, can make longitudinal edge be adjacent to each other, this makes outsideIt is enough little that housing can not be made. Thus, can carry out the compensation to tolerance by this gap. But,Can be susceptible to, tolerance is arranged so that for the open ended internal part of minimum andSpeech, longitudinal edge is adjacent to each other just. But preferred version is, though for minimal parts andSpeech is also provided with gap in external shell.
But because this gap is relatively little, therefore this inner shell part can be designed to makeObtain it the contribution of outside shell stability is obviously less than to this external shell part, thus inner shell partWeight and manufacturing cost can be lowered.
In the time observing cross section, this inner shell part can have the circumference less than external shell partSpend, be preferably its 0.6 times or less. Can save significantly thus material.
Can certainly use following inner shell part, this inner shell part is compared with external shell partThere is onesize and even larger than external shell part circumferential length.
Inner shell part also can extend in the c-shaped mode of cross section, and inner shell part is sameThere is the longitudinal edge further inwardly drawing than situation about taking the shape of the letter U. As select or in addition, inGap between the longitudinal edge of portion's housing component should be oriented to the longitudinal edge with external shell partEdge is relative, and the gap particularly advantageously and between external shell part longitudinal edge is relative. At cylinderIn the external shell of shape, the gap that can be defined as between the longitudinal edge of inner shell part is positionedBecome completely relative with the longitudinal edge of external shell part, particularly with external shell part on gap completeRelatively complete. This can provide uniform pliability for external shell.
External shell part should be thicker than inner shell part, particularly at least thick 1.3 times. This will saveWeight and material. In addition, avoided making external shell at the overlapping region of housing component ratio at all the other notThe obvious elasticity in overlapping region reduces.
In experiment, the thickness that has been found that external shell part can be no more than 1.0mm, particularlyThe thickness that is no more than 0.8mm and/or inner shell part can be no more than 0.4mm. These thicknessBe less than widely respective thickness of the prior art, in the prior art, for example, adopt 1.2mmTo 1.5mm thick roll shell wall.
Preferred embodiment even can make external shell part have to be no more than 0.4mm thickness,Be in particular 0.3mm thick, and make inner shell part only there is the thickness that is no more than 0.2mm.Especially the little thickness of inner shell part not only has lightweight advantage, also can guarantee in inner shellOnly there is little sudden change in the thickness of the region peripheral housing of the longitudinal edge of body part. Thus, limitThe end face of longitudinal edge inwardly stretches out hardly and forms for adjacent part, for example, for mounting matDisturb profile or Clutter edge, make in the time closing external shell, almost without any shearing forceBe applied on this adjacent part. Because thickness is little, therefore, longitudinal edge can installed hardlyPad place is stuck, but slides along this mounting mat.
The little thickness of inner shell part and external shell part also causes the following fact: due to external shellPart is more more pliable and tougher than of the prior art, and adapts to best the inside portion such as plug-in unitThe different geometries relevant with tolerance of part, therefore the stress distribution in this external shell is veryUniformly. This also means that chucking power is uniformly distributed into internal part very much.
The little thickness of external shell also causes the following fact: so-called canned (canning) process existsDuring the manufacture of external shell, realized quickly and can not produce large screen resilience, this is existingIn technology, be need to be improved. These screen resiliences cause the following fact: suppose it is other geometryAnd chucking power in the higher part of extent of rebound is lowered manyly, be open in its closureAfter press power is applied to the instrument on external shell by operating period, this external shell is by resilience.
In another embodiment of the present invention, external shell part is by different from inner shell part anotherA kind of material is made. Here can be cost-saving in addition, its reason is, for example inner shell partMaterial that can be lower by the quality different from external shell part is made.
External shell part should form housing exterior periphery at least 90%.
When at least one longitudinal edge tool in a circumferential direction in the longitudinal edge of external shell partWhile having at least one teat, the stability of external shell in the region of longitudinal edge can be enhanced alsoAnd manufacture and can be simplified, wherein, this at least one teat is bonded on and is positioned at relative teat regionRecess in. Teat and recess can be designed to complementation especially. Longitudinal edge is via teat and recessedPortion is in axial direction linked closely, and this has reduced the load of the connecting portion that acts on storeroom. This is preferredUnder embodiment, it is jagged that two longitudinal edges all can be designed to, and makes a longitudinal edgeThe peak of edge is bonded on the peak-to-peak complementary recess in top that is arranged in another longitudinal edge. But, spyNot, in order to maintain this circumferential clearance, the end at peak should not contact " bottom " of adjoining recess.But, can there is contacting in axial direction at the peak of adjoining and the lateral surface place of recess.
The longitudinal edge of external shell part should be brazed to each other and/or be brazed to inner shell part,Wherein preferably, external shell part is spot welded to extraly inner shell in the region of longitudinal edgePart. Inner shell part can form bridge between longitudinal edge, and this is the longitudinal of external shell partEdge is all brazed to the reason of inner shell part. Gap between longitudinal edge very hour,This gap also can close completely with scolder, makes this scolder also by the longitudinal edge of external shell partEdge is connected to each other. It is possible filling up this gap completely with scolder.
Preferably, the inner side in the region in its longitudinal edge and inner shell at outside housing componentPart is also provided with scolder between the outside in this region, to obtain larger solder side. When interiorPortion's housing component and external shell part overlapping when very many, can be susceptible to, only by scolder settingOn near the inner side longitudinal edge of outside housing component, do not make so the whole overlay region of housing componentTerritory is connected with scolder.
Device according to the present invention comprises plug-in unit (catalyst converter or the particle filtering for purifying exhaust gasDevice), form silencer and/or comprise TEG module. This device is for comprising inner structure thereinThe prefabricated container of part, wherein, processes exhaust by this internals or to from exhaustEnergy change (acoustic energy or heat energy).
In another embodiment of the present invention did not both provide the prefabricated component of this device not provide to comprise yetAny container of portion's member. Exactly, this device is to connect for the pipe box of two contiguous pipe boxesPart. External shell part and inner shell part connect with fluid around the pipe box of two vicinities and by themThe mode connecing is coupled to each other. Housing component is preferably attached to pipe box by the connection of storeroom. Due toPipe box does not always have accurate external dimensions and geometry, therefore the best gas to pipe boxClose adaptation always can obtain by two compressible housing components.
But, the I. C. engine exhaust that also can be formed by two housing components according to device of the present inventionPipe. Here, when inner shell part at least on cross section, be closedly extend, at inner shell partLongitudinal edge between while there is not gap, or in the time that this gap is sealed completely by scolder, to thisBlast pipe is favourable. In addition,, in the time that housing component is made from a variety of materials, this blast pipe moreFavourable, this can meet different corrosion resistance needs. Like this, the wall thickness of blast pipe can be than above-mentioned rowThe wall thickness of tracheae is little, and therefore the weight of this blast pipe is conventionally lighter.
Preferably, external shell part covers inner shell part in the axial direction substantially completely.Even all thickness is little in the situation that, also can provide one to have relatively large steady at each housing componentDevice qualitatively, and this stability is roughly even in the axial direction.

Above-mentioned steps b) in, withAfterwards at least one in housing component heated, make scolder become liquid and by housing component prickerBe welded to each other.
As a kind of replacement scheme of impression scolder, also one or more scolder thin slice can be passed throughBe attached at such as spot welding method on the one or both sides of opposite side of housing component. Thin slice will be added subsequentlyHeat fusing.
In order to gain in strength, can be by housing component on the whole surface of its contact or on contact-making surfaceGround soldering mutually distributes. Scolder is stamped in the one or both in housing component, for example, wholeOn surface, impress or be embossed into the pattern such as band, grid, point. After heating,Having obtained scolder whole surface or segmentation connects. Even scolder is embossed into pattern, scolder alsoCan after heating, make it to become the connection on whole surface.
Scolder whole surface or segmentation connects special in the parts band of position attached from outsideWork, to strengthen the shell wall in this region.
Due to the major part for closed this housing component pressure being applied to from outside housing componentInstrument is very expensive, thus should shorten their cycle time as far as possible, therefore, can be at prickerBefore weldering, housing component is spot welded to each other. Like this, both can be by housing component relative positioning and can be byIt is transported in another instrument or another station.
For cycle time of so-called canned (canning) process of closed this external shell neverOnly within 30 seconds, shorten to less than 7 seconds.
In the time housing component being positioned in the instrument that comprises the jaw claw that can move inward, can they are pre-Bending. In the time that these jaw claws are moved inward, make at least further bending of external shell part, it is verticalMove towards each other to edge. In this instrument, at least pass through for example spot welding by housing component to each otherPreliminary fixing.
