Definitions

  • the present invention relates to an exhaust gas treatment arrangement according to the preamble of claim 1, 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 from the exhaust gas leaving an internal combustion engine or to subject the exhaust gases to a catalytic reaction.
  • Such an exhaust gas treatment device to be integrated into the exhaust gas flow path of an internal combustion engine is known from the JP 2003 176717 A is known and is constructed with a substantially cylindrical, for example, circular cylindrical, extending along a support longitudinal axis, tubular support.
  • This carrier is formed with two, for example, substantially identical carrier elements, generally also referred to as half-shells.
  • 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 catalytic converter 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.
  • an exhaust gas treatment arrangement in particular for an exhaust gas flow path of an internal combustion engine, comprising a tube-like carrier body extending along a carrier longitudinal axis with a first axial end region and an axial end region and at least one carried in the carrier body with intermediate storage of at least one fiber material layer
  • the exhaust treatment element wherein the support body comprises two support members interconnected in a first connection region and a second connection region, the first connection region and the second connection region extending from the first axial end region to the second axial end region, at least one connection region extending from the first axial end portion to the second axial end portion does not extend parallel to the carrier longitudinal axis.
  • connection areas By configuring at least one, preferably both, of the connection areas in such a way that they do not extend or extend substantially obliquely relative to the support longitudinal axis, during manufacture of the support body, ie when the two support elements move toward one another in the longitudinal direction of the support in a generally substantially orthogonal merge movement direction, such force is exerted on the fibrous material surrounding an exhaust treatment member, the fibers thereof are not drawn outwardly but are pressed inwardly and thus do not accumulate where the two support members in the two connection portions are in mutual contact to connect and connect with each other. This avoids machining operations for pressing the fibers inwardly before the two support members are moved towards each other or brought into mutual contact.
  • the first connection region extends from the first axial end region to the second axial end region relative to a reference plane containing the longitudinal axis of the support, and the second connection region extends from the first axial end region extends to the second axial end region with respect to the reference plane to the first connection region in opposite directions employed.
  • the carrier body is substantially cylindrical, preferably with a round, for example circular or elliptical, peripheral contour, and that the first connection region and the second connection region extend helically from the first axial end region to the second axial end region in the same direction around the circumference of the carrier body.
  • a stable connection of the two carrier elements with one another can be achieved, for example, in a simple manner in that in the first connection region and in the second connection region, the first carrier element and the second carrier element each comprise a connecting section extending substantially radially outward relative to the carrier longitudinal axis.
  • the first carrier element and the second carrier element are designed as sheet metal forming parts that are preferably identical to one another. Furthermore, a connection of the two carrier elements, in particular an exhaust gas-tight connection, can be obtained with one another in that they are connected to one another in the first connection region and in the second connection region 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 an embodiment of an exhaust treatment system, generally designated 10.
  • 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 a substantially tubular, cylindrical shape, for example with a 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.
  • a reference plane E containing the carrier longitudinal axis L which are intersected, for example, by the two connecting regions 22, 24 in their longitudinal center region, the two connecting regions 22, 24 are arranged, that is to say they are angled.
  • the two connection regions 22, 24 are set in opposite directions with respect to this reference plane E, so that due to the substantially circular Circumferential contour of the carrier body 12 results in a substantially helical and co-directional extension of the two connecting portions 22, 24 along the circumference of the carrier body 12.
  • 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 carrier 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.
  • 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.
