Definitions

  • the present invention relates to an exhaust gas treatment arrangement which can be arranged, for example, in the exhaust gas flow path of an internal combustion engine of a motor vehicle to filter soot particles out of the exhaust gases leaving an internal combustion engine or to subject the exhaust gases to a catalytic reaction.
  • a substantially cylindrical for example circular cylindrical, extending along a support longitudinal axis, tubular support.
  • This carrier is with two z.
  • substantially identical carrier elements also commonly referred to as half shells formed.
  • the carrier elements each have connecting portions extending from the first axial end region of the carrier body to be produced to the second axial end region of the carrier body and extending substantially parallel to the carrier longitudinal axis.
  • an exhaust gas treatment element designed, for example, as a soot particle filter element or catalyst element is firstly arranged in one of the carrier elements, wherein the exhaust gas treatment element is surrounded on its outer peripheral region by at least one layer of this fiber material firmly locking in the finished carrier body. Subsequently, the other carrier element is moved towards the carrier element already containing the exhaust gas treatment element in a direction of convergence, wherein the connecting sections of the two carrier elements are each arranged essentially in a plane orthogonal to the direction of movement of the merging movement.
  • a method of manufacturing an exhaust treatment arrangement is known.
  • two, for example, mutually identical support elements are used with approximately U-shaped cross section, wherein the two U-legs of each support element, starting from a connecting these, arcuate connection region, have different lengths.
  • Each of the support elements has at its shorter U-leg on a remote longitudinal edge, which provides a receiving space for the longer U-leg of the other support member in which it can be slidably received.
  • the two carrier elements can be brought into a suitable positioning by moving relative to each other in order to be able to receive an exhaust gas treatment element embedded in a fiber material system in the interior space enclosed by the latter.
  • the measures a) and b) comprise the provision of the first carrier element and the second carrier element as mutually preferably substantially identical Blechumformmaschine, the carrier body can be produced on the one hand in a simple and cost-effective manner, on the other hand, however, also consists of a material which withstands the high temperatures generally generated in the exhaust gas flow path of internal combustion engines due to the heat carried in the exhaust gases.
  • the first connection section with the third connection section and the second connection section with the fourth connection section substantially simultaneously come into contact.
  • the offset of the first connection section with respect to the second connection section substantially corresponds to the offset between the third connection section and the fourth connection section, at least in the final phase of the mutual movement of the two support elements.
  • the inventive method advantageously comprises prior to the measure e) a measure f) for positioning at least one exhaust treatment element surrounded by at least one layer of fiber material in the first carrier element or the second carrier element.
  • a measure g) for connecting the first connection section to the third connection section and the second connection section to the fourth connection section preferably by welding.
  • At least one exhaust gas treatment element can be designed as a soot particle filter element. Alternatively or additionally, at least one exhaust gas treatment element may be formed as a catalyst element.
  • the Fig. 1 and 2 show a non-inventive embodiment of a generally designated 10 exhaust treatment device.
  • the exhaust gas treatment arrangement 10 comprises a carrier body 12 which, in the example shown, is formed with two support elements 14, 16 constructed essentially identically to one another.
  • the two carrier elements 14, 16, which are generally also referred to as half-shells, are preferably provided as sheet-metal formed parts and together form a carrier body 12 with substantially tubular, cylindrical shape, for example, with circular or elliptical peripheral contour.
  • the carrier body 12 extends along a carrier longitudinal axis L, which in the Fig. 1 is substantially orthogonal to the drawing plane and in the Fig. 2 lies in the drawing plane.
  • the carrier body 12 has a first axial end region 18 and a second axial end region 20. In these axial end regions 18, 20, the carrier body 12 can be connected to further line regions of an exhaust gas flow path of an internal combustion engine.
  • the two support members 12, 14 are fixedly connected to each other.
  • the first carrier element 14 has a first connecting section 26, which extends essentially radially outward relative to the longitudinal axis L, for the first connecting region 22 and a second connecting section 28 for the second connecting region 24.
  • the second carrier element 16 for the first connection region 22 has a third connection section 30 extending essentially radially outward with respect to the longitudinal axis L, and a fourth connection section 32 for the second connection region 24.
  • the first connecting portion 26 of the first support member 14 abuts the third connecting portion 30 of the second support member 16 in the assembled state.
  • the second connecting portion 28 of the first support member 14 abuts the fourth connecting portion 32 of the second support member 16.
  • the two support elements 14, 16 are preferably fixedly connected to each other by welding.
  • the two connecting portions 22, 24 and thus also the connecting portions 26, 30 and 28, 32 do not extend parallel to the body longitudinal axis L.
  • the two connecting regions 22, 24 are arranged, that is to say they are angled.
  • the two connecting regions 22, 24 are set in opposite directions with respect to this reference plane E, so that, due to the substantially circular peripheral contour of the carrier body 12, a substantially helical and co-extensive extension of the two connecting regions 22, 24 along the circumference of the carrier body 12 results.
  • the oblique position of the two connecting regions 22, 24 ensures that in the manufacturing process of the exhaust treatment arrangement 10 when the two support elements 14, 16 are moved together in a direction of assembly movement Z fibers of the exhaust material treatment element 34, which is also shown in sections, generally also referred to as a bearing mat, for example, as a fabric-like material or non-woven ceramic material, do not accumulate in the mutual joint portion of the connecting portions 26 and 30 or 28 and 32.
  • the support body 12a is constructed with two substantially identical to each other, for example, as Blechumformmaschine provided, half-shell-like support elements 14a and 16a.
  • the providing the connection areas 22a and 24a Connecting portions 26a, 28a, 30a and 32a extend in this embodiment substantially parallel to the longitudinal axis L of the carrier and are preferably located diametrically opposite to each other.
  • the first carrier element 14a When assembling this design variant of an exhaust gas treatment arrangement 10a, the first carrier element 14a is initially positioned, for example, such that its connecting sections 26a, 28a are offset from one another in the direction of the merging movement and have, for example, an offset V 1 . Before or after the positioning of the carrier element 14 in such a way, the exhaust gas treatment element 34a surrounded by the fiber material 36a can be positioned in the carrier element 14a.
  • the second support member 16a in the Caribbean Glassterrorismscardi Z is moved to the first support member 14a.
  • the second carrier element 16a is likewise positioned such that its connecting sections 30a and 32a have an offset V 2 in the direction of assembly Z, which is preferably substantially identical to the offset V 1 of the two connecting sections 26a, 28a of the carrier element 14a.
  • connection portions 26a and 30a providing the first connection portion 22a and the connection portions 28a, 32a providing the second connection portion 24a substantially mutually contact each other at the same time.
  • the two carrier elements 14a can be connected to one another in a fixed and exhaust gas tight manner by welding.
  • two or more exhaust gas treatment elements could be arranged in a carrier body.
  • the carrier body could basically also have a contour tapering in the direction of the body longitudinal axis L or a curved shape with a correspondingly curved body longitudinal axis.
