Definitions

  • the invention relates to an exhaust manifold fastening device for locking the exhaust manifold on the engine block side, with a manifold flange facing the engine block, which has recesses for the passage of engine block-side extensions.
  • Exhaust manifolds are releasably attached to the engine block with bolts. Important is the accessibility of the bolts for assembly and disassembly for changing the manifold. However, the assembly and disassembly is difficult because the exhaust pipes sometimes close very close to the area of the bolts or even partially (seen in the direction of the flange and thus in the screwing the bolt) cover.
  • the invention provides a simple, quick exhaust manifold mounting means and a method of locking an exhaust manifold to an engine block characterized by easy assembly and disassembly.

  • the exhaust manifold fastening device according to the invention thus does not provide for the locking by movement of a fastening part perpendicular to the engine block, as in the case of the threaded bolts, but in a plane perpendicular thereto and thus parallel to the manifold flange or the engine block side flange. This facilitates accessibility during assembly and disassembly.
  • the elbow-side part is preferably a locking part provided on the rear side of the elbow flange, wherein alternatively the elbow flange itself could be designed to be transversely displaceable and thus lockable.
  • a conceivable embodiment of the locking part is a simple plate.
  • the locked part should be designed so that it allows plugging and thus pre-positioning of the exhaust manifold on the extensions and only then the lock.
  • This assembly with coarse direction and subsequent locking can be realized, for example, by providing a keyhole opening in the manifold side part through which extends the associated extension.
  • the manifold side portion should also be biased in the locked position, substantially perpendicular to the plane defined by the manifold flange, to prevent rattling and disengagement of the latch.
  • This bias can be done for simplicity's sake by the manifold-side part itself, for example by this has elastic projections, which provide in the locked position for the bias.
  • the extensions are in particular motor block side preassembled bolt head.
  • the method according to the invention for locking an exhaust manifold to an engine block is characterized in that a manifold-side member is displaced in a plane parallel to a plane defined by the manifold flange transversely to protrusions which pass through recesses in the manifold to reversibly connect the manifold flange and associated protrusions lock.
  • the assembly takes place in two steps, namely by first the manifold is fitted onto the engine block, so that the projections pass through the recesses and coarse positioning takes place, and then by the Quer ⁇ shift of the manifold side part the actual locking takes place.
  • FIG. 1 shows the manifold attached to an engine block in an embodiment of the fastening device according to the invention
  • FIG. 2 shows a perspective view of the manifold attached to the engine block according to FIG. 1,
  • Figure 3 shows the manifold of Figure 1 in the engine block mounted state, with separated exhaust pipes for better visibility of the invention

  • an exhaust manifold 10 is shown, which is attached to an engine block 12 of a four-cylinder engine.
  • the exhaust manifold 10 has four exhaust pipes 14, each having a respective engine block side outlet
  • All exhaust pipes 14 are attached to their engine block end to a Krümmerflansch 20, which is designed as a flat plate to abut flat on the plan in this area also engine block 12 gas-tight.
  • the exhaust pipes 14 are angled shortly after the Krümmerflansch 20 by almost 90 ° downwards, as can be seen well in particular in Figure 2, then run toward each other in a funnel shape and to unite to the common exhaust pipe 18.
  • the exhaust manifold 10 is screwed above the exhaust pipes 14 by numerous bolts 22 to the engine block 12, with always a ring ⁇ bolt 22 left or right above the associated exhaust pipe 14 is seated as close to the associated exhaust pipe 14 to apply the clamping force and gas tightness to care.
  • All bolts 22 are unhindered and easy to reach, since the exhaust pipes 14 are angled downward and do not complicate the access by means of a tool to the bolt 22.
  • a very simple fastening device for an exhaust manifold is provided in the region of the lower edge 24.
  • a locking member 28 which has the shape of a

  • Engine block 12 are pre-assembled projections in the form of short bolts 30 with
  • Head 32 is provided. Approximately in the middle of each exhaust pipe 14, as Figure 3 can be seen well, a bolt 30 is provided on the engine block side. The respective head 32 is clearly spaced from the engine block 12.
  • Bolt 30 has a recess which is large enough to attach the exhaust manifold 10 on the bolts 30 in the longitudinal direction of the bolt 30.
  • the locking part 28 has recesses in the form of keyhole openings
  • the fitting of the exhaust manifold 10 on the bolts 30 can be carried out simultaneously or before the attachment of the locking member 28 on the bolts 30, depending on whether the locking member 28 and the exhaust manifold 10 form a preassembled unit or not.
  • the locking part 28 is in the region of the keyhole openings 34, starting from that with a larger cross section provided portion of the keyhole opening 34 to the head 32 bent obliquely upward.
  • This bent portion forms a resilient projection 36 for the associated head 30, so that in the locked position, the Be ⁇ fastening device is biased perpendicular to the plane E.
  • the lock is of course reversible to release the exhaust manifold 10.
  • the keyhole openings 34 are arranged to the bolts 30, that a simultaneous locking or a simultaneous release of the bolts 30 and the exhaust manifold 10 is effected by means of a movement.
  • the locking member 28, as shown in Figure 3 can be seen, angled at 90 ° on the left end, so that there is a protruding tab 38.
  • the manifold flange 20 has an angled tab 40 in this area so that the tabs 38, 40 abut each other in the locked position and a fuse 42 interconnects the tabs 38, 40, e.g. a nut-nut connection passes through openings in the flaps 38, 40.

  • the two middle bolts 30 are completely covered by the exhaust pipes 14 and the two outer bolts 30 are partially concealed or are so close to the exhaust pipes 14 that the accessibility for a tool is not given, is in the region of the lower edge 24 by means of the locking member
  • the bolts 30 can also be regarded as part of the exhaust manifold fastening device.
  • the locking member 28 could also be mounted on the engine block and after fitting the Krümmerflansches 20 are moved to the extensions for locking the Krümmerflansches 20.
