Definitions

  • the present invention relates to an exhaust system for an internal combustion engine driven motor vehicle, wherein the various components are adjustable with respect to each other.
  • the first pipe section has a tulip-like extension
  • the inner surface is designed as a spherical sealing surface
  • the outer surface of the sealing ring is designed to correspond to the sealing surface of the first pipe section and the spherical seal surface over a large area on the sealing surface of the first pipe section is applied. Due to this, the sealing rings, which serve not only the sealing of the two pipe sections against each other, but also the mechanical support of the pipe sections to each other, comparatively large size, which when using a material optimized in view of the specific mechanical and thermal requirements material to not inconsiderable costs for the respective sealing ring leads.
  • a quick release pipe coupling is known, with which two pipes can be connected together.
  • One of the tubes has a spherical sealing surface, in which a groove is formed, in which a sealing ring is arranged.
  • the other tube has a tulip-shaped counter surface, in which the sealing surface is received with the sealing ring.
  • the invention has for its object to provide an exhaust system that reliably and permanently meet existing requirements in practice, which include in particular the ever-increasing demands on the tightness at comparatively low manufacturing and maintenance costs, in particular a disassembly and subsequent Reassembly of the exhaust system in the ball zone connection without adverse effects should be possible.
  • the exhaust system according to the invention is thus characterized in particular by the fact that the mechanical loads between the two interconnected in the ball zone connection components of the exhaust system on both sides of the sealing ring on the spherical sealing surface of the first pipe section adjoining spherical contact surfaces of the second pipe section are transmitted. This results in the greatest possible mechanical relief of the sealing ring.
  • sealing rings which are considerably more cost-effective than the sealing rings required for the generic exhaust systems specified at the outset. Due to the mechanical relief of the sealing ring whose wear is also reduced; This leads to a particularly permanently sealed connection of the two components in the area of the spherical zone connection. In this case, a disassembly of the exhaust system in the region of the spherical zone connection with subsequent reassembly even without impairment of the function is possible if the position of the two components to be interconnected deviates from the original position in the reassembly of the exhaust system.
  • a particular advantage of the solution according to the invention is the possibility of a comparatively smooth outer surface of the exhaust system in the region of the spherical zone connection, which is particularly favorable for exposed exhaust systems of motorcycles from an aesthetic point of view.
  • no special requirements are placed on the further components of the connection of the two components, such as clamps and the like.
  • clamps can be used whose inner surface corresponds to the spherical outer surface of the tulip, so that clamp and tulip readily in different positions can rest against one another comparatively over a large area.
  • the present invention can be applied in the case of the execution of the exhaust system as such for a motorcycle.
  • For motorcycles must often be removed to change the rear of the muffler, which is possible according to the above embodiments in the case of the execution of the exhaust system according to the present invention easily and without affecting the function after the subsequent reassembly of the muffler.
  • the spherical contact surfaces do not necessarily have to be completely closed circumferentially. Rather, the spherical contact surfaces can also be divided under particularly stored conditions, so that the power transmission between the interconnected components distributed over several individual zones. It is important, however, that according to the essence of the present invention on both sides of the sealing ring, a mechanical contact of the two pipe sections to each other via the standing with the spherical sealing surface of the first pipe section in contact Contact surfaces of the second pipe section exists.
  • the exhaust system only partially illustrated in the drawing comprises two components (not shown), which are interconnected in the area of the spherical zone connection 1.
  • One component is a first pipe section 2 and the other component is a second pipe section 3 assigned.
  • the first pipe section 2 has a tulip-like extension 4. Its inner surface 5 is designed as a spherical sealing surface 6, on which a sealing ring 7 rests.
  • the sealing ring 7 is inserted in a bead-like recess 8, which is circumferentially rolled on the end formed on the second pipe section 3, executed in the form of a spherical zone 9 extension.
  • the ball zone 9 is designed such that its outer surfaces bearing surfaces 10 and 11, which are intended for surface contact with the sealing surface 5 of the first pipe section 2.
  • a ball clamp 12 is provided, with which the pipe sections 2 and 3 are clamped against one another by abutment of the contact surfaces 10 and 11 on the sealing surface 5.
  • the outer surfaces of the tulip-like extension 4 of the first pipe section 2 and the extension of the second pipe section 3 in the region of the contact zone 13 for the ball clamp 12 are spherical with a common, the center of curvature of the sealing surface 5 and the contact surfaces 10 and 11 corresponding center of curvature to a uniform , planar contact the ball clamp 12 to the two pipe sections 2 and 3, even with different angular positions of the two pipe sections with respect to each other to allow.
  • a clamp could be provided, which rests on one of the pipe sections, for example, the second pipe section 3 in the region of the contact zone 13 of the extension, in a conical or otherwise suitably shaped outer surface.
