Definitions

  • the invention relates to an arrangement for fastening the exhaust system to the exhaust manifold of an internal combustion engine with a holder supporting the exhaust system, which is connected to the exhaust gas duct between the exhaust manifold and exhaust system via at least one metal bellows on the exhaust manifold and via axial vibration dampers with their axes in one plane, preferably made of steel wire mesh, with is connected to the exhaust manifold or the cylinder head.
  • a mounting arrangement for an exhaust system of an internal combustion engine is known from DE-OS 3321382.
  • a plate is attached to the exhaust manifold, which in turn supports the holder by means of two axial vibration dampers made of steel wire mesh, to which two exhaust pipes are welded, a metal bellows then being provided between the holder and the plate for each of these exhaust pipes.
  • the axial vibration damper merely having the task of keeping the deformations of the metal bellows within permissible limits without forming a sound bridge.
  • the exhaust system includes an exhaust gas turbine, which must then also be carried by the holder, the operation of the motor vehicle equipped with the exhaust system or during engine operation itself results in comparatively large dynamic forces, which are impermissibly high deformations of the metal bellows in the known holder suspension bring with it and thus lead to premature bellows destruction.
  • the object of the invention is to eliminate these deficiencies and to improve the arrangement described at the outset in such a way that that despite good structure-borne noise interruption, no damage to the metal bellows or the metal bellows is to be feared even when large dynamic forces occur.
  • the invention achieves the stated object in that a total of six axial vibration dampers are provided around the metal bellows or the metal bellows, but only the axes of three of these dampers lie in a common plane, at least one of the axes being the axes of the other dampers in the plane intersects and that the axes of the three remaining dampers run parallel to one another and penetrate the plane of the axes of the dampers or form a tripod whose intersection lies outside the plane of the axes of the dampers.
  • This arrangement of the axial vibration damper ensures that, regardless of the type of stress, all dampers are only loaded by axial forces, that is to say by forces which bring about the slightest deformation of the damper and thus also of the metal bellows. Shear forces and moments would result in far greater deformations.
  • the axial vibration dampers are accommodated in cup-shaped recesses in the cast holder or in brackets provided from the exhaust manifold or cylinder head and are each connected to the other component by a bolt penetrating the recess bottom.
  • the cast holder forms two channels leading from the two metal bellows to the end of a double-flow exhaust gas turbine. In this way, a mutual influence of the separated gas streams is prevented and nevertheless a close arrangement of the gas inlet openings in the turbine, which is necessary for the turbine Turbine enabled.
  • Consoles 2 are cast onto the two halves 1 and 1a of the exhaust manifold of an internal combustion engine, to which a holder 3 is fastened.
  • a two-flow exhaust gas turbine 3a is connected to the holder 3.
  • two metal bellows 4 are initially provided, the holder 3 forming two channels 5 leading to one another.
  • a total of six axial vibration dampers 6a, 6b are provided, of which the axes of the axial vibration dampers 6a lie in one plane, whereas the other three axial vibration dampers 6b are parallel are aligned with each other normal to this level, i.e. they pierce them.
  • the axes of the axial vibration dampers 6b could also form a tripod with a tip lying outside the plane mentioned. Only two of the axial vibration dampers 6a are arranged in parallel axes.
  • the axial vibration dampers 6a, 6b are accommodated in cup-shaped recesses 7 of the holder 3 and connected to sprues of the bracket 2 by bolts 8.
  • Each bolt is surrounded by a sleeve 9, which has a collar 10 within the recess 7. Between this collar 10 and the recess bottom on the one hand or an annular disk 11 held by a snap ring on the other hand, cushions made of steel wire mesh are clamped for vibration damping, which naturally have a corresponding heat resistance and resilience.
  • brackets 2 onto the exhaust manifold halves 1, 1a, but to fix them at a suitable point on the cylinder block.
