Definitions

  • the invention relates to a suction pipe for an internal combustion engine with a through a Insert reinforced flange for fastening according to the preamble of claim 1 or an insert for reinforcing flange components according to claim 4 or a Assembly method for suction pipes according to the preamble of claim 7.
  • Suction pipes with reinforcing components in the flange area are known.
  • is according to DE 196 13 279 A1 discloses a suction tube whose suction channels 10, 11, 12, 13 (see Figure 1 of this document) open into a cylinder head flange.
  • This cylinder head flange has passages 14, 15, 18, 19, which for fastening the Zylinderkopfflansches are provided by means of fastening screws. Since the suction tube out Plastic, these passages are according to Figure 2 of the document with reinforcing sleeves 22 provided which receive the pressure of the mounting screws and limit the deformation of the Zylinderkopfflansches in this way.
  • the object of the invention is therefore to provide a suction tube with a reinforced mounting flange or inserts to reinforce the flange to create a Assembly favored even in tight spaces. This task is done by the Characteristics of claims 1 and 4 solved. Furthermore, according to claim 7, a method placed under protection for mounting the suction tube.
  • the intake manifold according to the invention consists in a known manner from the intake air conductive structures.
  • the typical structure has a suction tube one Inlet that opens into a plenum from which the suction channels towards the cylinder head flange depart.
  • the suction pipe is attached to the cylinder head of the engine block.
  • the suction tube can, for. B. made of plastic or even light metal. These Materials contribute to the weight reduction of the vehicle. However, you have to reinforced such materials in the field of recordings for the fastener to allow reliable installation. Therefore, the images are using Strengthens inserts that surround the passages, for example.
  • Such reinforcing agents consist of bushings, which are made of steel or brass can, depending on the required stiffness of the reinforcing medium.
  • the invention is characterized in that both the passage passing through the Flange for attachment, in particular the Zylinderkopfflansch is formed, as well as Insert itself, which is introduced into the passage of the flange, to the edge of Flange are made open towards.
  • the passage is not off a closed sleeve, which has an upper and a lower opening for Passing through the fastening means, in particular a fastening screw has, but that the upper and lower openings are as it were through a kind of slit in the Side wall of the sleeve are connected.
  • This slot leads to the edge of the flange towards open design, so that the fastener from the side in the Passage can be introduced.
  • the fasteners can be preassembled at the installation site. In case of Fixing screws for a cylinder head flange so this can be in the cylinder head be screwed. Subsequently, the suction pipe by means of the open inserts be placed sideways on the pre-assembled screws. These must be followed only be tightened, causing the fastening tools only Perform a small joining movement of the screws or fasteners have to. In particular, the long axial joining paths of the fastening means are eliminated, which do not have to be plugged through the holes, which through the inserts according to formed in the prior art.
  • the insert is seen in cross-section designed essentially U-shaped.
  • the open side of the u's is then to the edge of the Flange aligned, whereby the introduction from the side is possible.
  • a further embodiment of the invention provides that several of the invention Inserts are used, which along the longitudinal side of the Zylinderkopfflansches are arranged.
  • the inserts can according to a further advantageous variant means for generating have a positive connection with the flange.
  • This is a design of the Inset, which prevents the assembled insert sideways out of the to Edge slipping out open flange.
  • This is advantageously in particular by to accomplish a circumferential bead, which for positive connection leads.
  • the means for generating a positive connection form a kind of undercut, which serves as a safeguard against slipping out.
  • the measure described by other typical measures be supported for the assembly of components.
  • the sleeves glued or used warm.
  • the material the flange component plastically deformed, whereby a positive connection can be generated can.
  • an excess of the insert also creates a traction which secures the insert against slipping out of the receptacle.
  • the suction pipe according to FIG. 1 has, in a known manner, an inlet 10 for the combustion air on, which opens into a collecting space 11. From this go suction channels 12th from, which open into a cylinder head flange 13. In these are various inserts 14a, b introduced, which are made of steel and so the cylinder head flange 13 from Reinforce plastic.
  • the inserts 14b are designed according to the prior art. Of special Interest is therefore the inserts 14a, which are constructed as follows.
  • the stakes 14 a are mounted in passages 15, which through the cylinder head flange thirteenth are formed.
  • the inserts themselves have bushings 16, which on one longitudinal side 17 of the cylinder head flange 13 are mounted, d. H. that these executions are open to the edge of Zylinderkopfflansches.
  • This assembly process is made possible by a U-shaped Formation of the associated insert 14a. You could also get a horseshoe-shaped one Speak training.
  • a flange 13 is shown, which z. B. a section of the Long side 17 of the suction tube according to Figure 1 could be.
  • the insert 14a is in perspective shown shortly before its assembly in the indicated direction of the arrow 19. It will be the U-shaped cross-section clearly and the attachment of an annular bead 20, the surrounds the curved part of the U-profile ring. This corresponds to installation the insert with a shoulder 21, which is formed in the passage 15. After installation of the insert 14 a is therefore against slipping out in the direction of Long side 17 secured by the form-fitting forming undercut 22.
  • the suction pipe according to Figure 3 is shown in section. To recognize is one of the suction channels 12, the collecting space 11 and the cylinder head flange 13 in section. The insert 14a is also cut so that the passage 16 can be seen.
  • the bushing 16 comes with a fastening screw 26 in contact and is provisionally fixed. The final fixation will be caused by tightening the mounting screw 26.
  • the illustrated joining direction 23 is thus by the longitudinal side 17 toward open passage 16 of the insert 14 a allows.
  • FIG. 4 a once again shows the insert 14 a according to FIG. 2 as a plan view. additionally is a dropout 27 of the insert with rounded edges 28 executed, what an insertion of the fastener, not shown in the implementation 16 facilitated. To recognize is still in this view particularly well the undercut 22nd
  • FIG. 4b shows a further version of the insert 14a. This has little noses 29, soft on the outside of the insert are molded. Therefore, the use is suitable particularly good to be cast in a flange plastic component, wherein the final fixation is achieved by the lugs 29.
  • the insert 14a according to FIG. 4c is shown in a side view. He has a den Shell of the insert circumferential corrugation 30 on, which is why the use in particular is suitable to be used as a hot insert.
