Description

  • The The invention relates to a flat gasket according to the generic part of first claim.
  • Of the DE 195 23 311 A1 is a seal, in particular metal seal, to remove for sealing two metallic surfaces, which are clamped together by means of at least one threaded fastener. Holes for receiving threaded bolts are provided in the area of the metal plate. In the region of at least one layer of the metal gasket bore side, inwardly facing tongues are provided, the same when inserting the threaded bolt into the thread of the same are introduced.
  • By the EP 0 967 421 A1 a flat gasket made of sheet metal with centering holes has become known, wherein for centering a threaded shaft, the sheet metal layer in its adjacent to the screw hole edge region at least one formed by the sheet metal layer and herausgebogenes from the plane, an intervention of the sheet metal layer in a thread preventing centering, which when tightening a screw is at least approximately zurückbiegbar in the plane of the sheet metal layer. In eccentric arrangement of the seal, it may happen in the course of the assembly process that one or more of the centering, at least partially engages the thread, but this is not desirable. A disadvantage is also noted here that bent by 90 ° centering when tightening the screw can tend to wrinkles.
  • Of the US 5,259,629 A is to remove a multilayer flat gasket, which is provided with a plurality of through holes for a variety of purposes.
  • Available are guide holes for bolts, taking In the area of at least one of the sheet metal layers tongues are provided. When pushing the gasket on the bolts, the tongues opposite to the mounting direction deformed and thus prevent a drop of the seal from the bolt. Alternatively, here is the possibility given to provide bent tongues formed out of the sheet metal layer, which have the same effect as stated above.
  • All the flat gaskets are intended exclusively for vertical mounting, whereby they have the disadvantage that due to tolerances and not excludable eccentric Laying during the assembly process when inserting threaded bolts the same can not be positioned exactly one hundred percent, so that it in certain circumstances can lead to leaks, especially modern engine designs a require relatively exact positioning of sealing elements.
  • The EP 0 482 899 A1 discloses a generic flat gasket. At the outer edge of this gasket retaining clips are provided which serve to connect the gasket with a flange. The through holes present here are not designed as centering and guide holes. About the retaining clips, the seal is connected to the flange, but not centered.
  • Of the Invention is based on the object, in the generic Part of the first claim described to further develop flat gasket to that they, in particular for the purpose of essentially horizontal assembly, Such centered can be mounted that leaks in the operating condition no longer occur.
  • These Task is solved by that for an im substantial horizontal mounting of at least one of the through holes Centering hole and at least one further through hole a guide hole is that the hole bigger than that Centering hole is formed, that in the guide hole at least one obtusely pointing in the direction of a receiving element, off the sheet metal layer bent guide tongue is provided, and that both in the center hole and in the guide hole at least one centering element is provided.
  • advantageous Further developments of the subject invention are the dependent claims remove.
  • As a result the, in particular against the mounting direction of the flat gasket bent out of the sheet metal layer, preferably individual guide tongue is it now possible that at essentially horizontal mounting the guide tongue arranged in the guide hole do not enter the thread of a threaded bolt and thus lead to eccentric mounting can. Hooking during assembly are therefore no longer given.
  • Thus, especially against the EP 0 967 421 A1 , Achieved a significant installation advantage, especially since this document can not be ruled out that parts of the sheet metal layer engage in the thread and thus lead to eccentric assemblies.
  • According to a further aspect of the invention, centering tongues can be provided both in the area of the centering hole and the guide hole, which are analogous to the guide tongue from the Sheet metal are bent out, in the same direction as the guide tongue.
  • at essentially horizontal mounting tolerances in both x- as well as in y-direction can be easily compensated, as a close guidance in the Area of the centering hole (x-axis) is given while balancing possibilities in the area of the guide hole (y-axis) are given.
  • a According to further ideas of the invention, the guide tongue is formed longer as the Zentrierzungen, in order to be able to exclude in this way safely that in the course not accidentally but there is a penetration into the thread.
  • at Presence of centering elements in the area of the guide hole are selbige, preferably symmetrically provided for Zentrierzunge.
  • Of the Subject of the invention is based on an embodiment in the drawing and is described as follows. Show it:
  • 1 Top view of a metal flat gasket;
  • 2 Details of the centering and the guide hole according to 1 ;
  • 3 Cross sections according to the lines XX and YY according to 2 ,
  • 1 shows a, for example, for an exhaust manifold, not shown, usable flat gasket 1 to be formed in this example as a metal gasket. The flat gasket 1 should further be provided for a substantially horizontal assembly. The flat gasket 1 includes a plurality of through holes 2 . 3 . 4 , wherein for the description of the invention only the through holes 3 and 4 are of interest. The through hole 3 is formed as a centering hole, while the through hole 4 represents a guide hole, the latter being formed larger than the former. In mental representation of the centering and guide hole within a coordinate system with vertical X and horizontal Y-axis, the centering hole extends in the X direction and the guide hole in the Y direction. Like the naming of the holes 3 . 4 indicates, takes place in the area of the centering hole 3 relative to a threaded bolt, not shown centering in the X direction instead, while in the region of the guide hole 4 a compensation in the Y direction can be made without it during assembly of the gasket 1 can come to entanglements on the threaded bolt.
  • 2 shows cross sections on the one hand through the centering hole 3 and, on the other hand, through the guide hole 4 , Both in the area of the centering hole 3 as well as in the area of the guide hole 4 are from the sheet metal situation 5 . 6 bent out waist tongues 7 . 8th intended. To facilitate the substantially horizontal mounting of the gasket 1 is in the area of the guide hole 4 in this example, a single guide tongue 9 from the sheet metal layer 6 bent. Both in the area of the centering hole 3 as well as in the area of the guide hole 4 are further, in the respective X or Y direction protruding recesses 10 . 11 . 12 . 13 . 14 . 15 provided so that from the respective sheet metal layer 5 . 6 shaped centering tongues 7 . 8th or the guide tongue 9 through the head of a mother, not shown again in the direction of the sheet metal layer 5 . 6 can be bent back. Seen in the mounting direction is the guide tongue 9 arranged above the threaded bolt.
  • 3 shows cross sections according to the lines III-III and IV-IV of 2 , The line IV-IV in this case relates to the guide tongue 9 in the area of the guide hole 4 the flat gasket 1 , Visible is a threaded bolt 16 which is arranged in the vertical direction. The mounting direction is indicated by an arrow. The guide tongue 9 is at an obtuse angle with respect to the plane of the sheet metal layer 6 , in the direction of the threaded bolt 16 directed, without the surface 17 (Thread) of the same come into contact. Penetration of the guide tongue 9 in a not shown thread of the threaded bolt 16 is thus not given, but as a result of the obtuse bent guide tongue secure guidance is ensured within the specified tolerances.
  • Section III-III concerns the centering tongue 7 (or 8th ) in the region of the centering hole 3 the flat gasket 1 , Also the centering tongues 7 (respectively. 8th ) are at an obtuse angle with respect to the plane of the sheet metal layer 5 (respectively. 6 ) is bent in the direction of a threaded bolt, not shown, wherein the angle is greater than that of the guide tongue 9 , The mounting direction is also indicated by an arrow.
