Definitions

  • the invention relates to a method for producing a cylinder head cover for an internal combustion engine according to the preamble of claim 1 and a cylinder head cover according to the Preamble of claim 4.
  • Cylinder head covers of today's internal combustion engines have to open the cylinder head well sealed and, if possible, isolated from structure-borne noise to be assembled.
  • Hood construction known, in which two hood parts from Metal sheet or light metal die-cast over vulcanized Rubber are interconnected, which is a sound-decoupled Connection between the two hood parts (US-PS 3,692,335). This rubber can also be used at the same time Formation of the seal in relation to the machined cylinder head surface serve (DE 26 38 982).
  • Plastic cylinder head covers save weight already used recently. A seal is included as in the case described above, separately between the mounting flange the cylinder head cover and the cylinder head surface trapped. With such plastic hoods has proven to be problematic turned out that due to the material Operation "set", which affects the tightness. For this Basically, such plastic hoods with incorporated metal Fastening sleeves made, which are the disadvantage Prevent the effects of setting when fastening, however, the effort involved in producing the plastic hood increase.
  • the invention has for its object a method for Manufacture of a cylinder head cover and a cylinder head cover of the type mentioned in the introduction to the manufacturing costs, sealing properties and decoupling equally satisfied.
  • a method according to claim 1 is used to achieve this object and a cylinder head cover according to claim 4.
  • the invention provides a direct, permanent and tight connection between the elastomer of the seal and the plastic the cylinder head cover by means of gluing and previous corona treatment at least one of the surfaces to be connected, like they have for many years in printing technology for the Printing on plastic surfaces is used (cf. "Pretreatment of plastic surfaces for printing and Marking "by M. Theiwes, company brochure ARCOTEC heatntechnik GmbH, December 1996). After a Such a corona treatment can be carried out according to the invention Elastomer seal with vulcanized metal Stiffeners permanently attached to the plastic hood part stick on.
  • a high-frequency corona treatment of those to be attached to the hood part Surface of the seal with the introduction of the prefabricated Elastomer seal between an electrode and a counter electrode with intensive electron bombardment of this elastomer surface made to so called the area of the seal to prepare for gluing with the hood.
  • a cylinder head cover In a cylinder head cover according to the invention Fastening screws for connecting the cylinder head cover with the cylinder head preferably directly on the metal frame. Rib-like projections of the elastomer part are advantageous the seal against the flat surface of the cylinder head flattened, these protrusions preferably inside the screw force points of attack are on the frame. So will a high sealing effect combined with excellent Sound decoupling and thus noise reduction achieved.
  • Fig. 1 shows schematically a section through a cylinder head cover 2, 4 in mounted on a cylinder head housing 1 Status.
  • the places where the cylinder head cover 2, 4 sealing rest on the cylinder head surface 12 are enlarged shown in Figs. 2 and 3, with Fig. 3 opposite Fig. 1 is drawn rotated by 180 °.
  • Reference number 2 is a hood part from one impact-resistant plastic.
  • Reference number 4 denotes a prefabricated elastomer seal, being in the elastomer material 6 of this elastomer seal in cross section essentially C-shaped metal frame 8 is vulcanized.
  • the Seal 4 On its side facing the cylinder head surface 12 has the Seal 4 has a rib-like projection 10, which in FIGS and 3 is drawn in the undeformed state, in the assembled However, it actually lies on the cylinder head surface 12 is pressed flat, so that at the point below the Tip of the projection 10 forms a pressure peak.
  • the cylinder head cover 2 has a flange 14, the underside of which 16 facing the top 5 of the seal 4.
  • On this Top 5 is the elastomer of the seal 4 by means of HF corona treatment activated and using a suitable adhesive glued to the underside 16 of the flange 14.
  • the flange 14 has claws 18, 20 projecting on both sides which he the upper part 9 of the seal 4 embraces.
  • the C-profile of the metal frame 8 has an offset 11 provided, which runs parallel to the cylinder head surface 12.
  • the limited in profile C-shaped metal frame 8 defines the Deformability of the elastomer material 6 of the seal 4 in Direction perpendicular to the cylinder head surface 12.
  • the cylinder head cover is produced according to the invention as follows:
  • the hood part is made from an impact-resistant plastic 2 shaped with the mounting flange 14 in a conventional manner, for. B. in the injection molding process.
  • the seal 4 with an inserted metal frame 8 by vulcanizing the elastomer material 6 in one Shape.
  • the seal 4 then has the shape according to 1 to 3.
  • the seal itself between an electrode and a grounded counter electrode located.
  • the metal frame 8 can serve as the counter electrode to serve.
  • the elastomer surface 5 the seal 4 with high frequency (25 to 50 kHz) with electrons shot at. Due to the intense fire in the Surface 5 broken the molecular chains. At the break points charged ions attach themselves to which molecules of a suitable one Can store adhesive.
  • the adhesive is in the form of a Caterpillar on the top 5 of the seal 4 and / or the bottom 16 of the mounting flange 14 of the hood part 2 applied.
  • the hood part 2 and seal 4 are in one heatable, preheated adhesive device (not shown) introduced, in which the parts in glued position in closed State for a given dwell time on a given Curing temperature can be maintained.
  • the residence time was 15 min. and the curing temperature 180 ° C.
  • the adhesive device is opened and it is the finished cylinder head cover 2, 4 with fixed to the cover part 2 glued seal 4 removed from the gluing device.
  • a good decoupling of noise is on the one hand by the choice a suitable plastic as the material of the hood part 2 and on the other hand through the direct gluing of the hood part 2 with the elastomer of the seal 4 without the interposition of sound-transmitting metal elements achieved.
  • FIGS. 4 and 5 show the two connection points on the left and right analogously to FIG. 1 between cylinder head cover 2, 4 and cylinder head housing 1, identical or equivalent parts for the sake of simplicity are assigned the same reference numerals.
  • the metal frame 8 is S-shaped in cross section and lies only in a limited area outside the screw connection directly on the cylinder head surface 12.
  • the distance between Cylinder head surface 12 and screw head 24 are at this embodiment by a collar portion 26 of the screw 22nd bridged.
  • Preferred materials for the production of the hood part 2 are Polyamide (PA 6.6) or polyphenylene (PPS) with glass fiber reinforcement and / or mineral filling.
  • Acrylate rubber is preferred as the elastomer material of the seal 4 (ACM), ethylene-acrylate rubber (AEM) or fluorine rubber (FPM) used.
  • the frame 8 is advantageously drawn from sheet steel and punched or as a die-cast part made of a light metal alloy, in particular Al alloy.
