Definitions

  • the present invention relates to an internal combustion engine.
  • an internal combustion engine comprises a cylinder head and a cylinder head cover. Furthermore, an intermediate flange may be arranged between the cylinder head cover and the cylinder head, which forms a separate component with respect to the cylinder head cover and the cylinder head. Components of the internal combustion engine may be arranged in the intermediate flange, for example components of a fuel injection system and / or components of an ignition system.
  • the components accommodated in the intermediate flange can have an increased sensitivity to vibrations and vibrations which, for example, can be introduced into the intermediate flange via the cylinder head. This can affect the long-term reliability of these components.
  • the present invention is concerned with the problem of providing for an internal combustion engine of the type mentioned an improved or at least another embodiment, which is characterized in particular by a reduced vibration load of the intermediate flange and the components housed therein.
  • the invention is based on the general idea of decoupling the intermediate flange relative to the cylinder head via a first sealing arrangement relative to the cylinder head and via a second sealing arrangement relative to the cylinder head cover.
  • the seal assemblies is characterized assigned a dual function, since on the one hand cause the required seal between the flange and cylinder head on the one hand and between the intermediate flange and cylinder head cover and also cause the vibration decoupling between the intermediate flange and cylinder head on the one hand and between the cylinder head cover and intermediate flange on the other.
  • the invention uses the consideration that elastic materials suitable for the seal can simultaneously also be suitable for vibration decoupling.
  • the invention also proposes not to attach the intermediate flange directly to the cylinder head, but only indirectly via the cylinder head cover, namely by fastening the cylinder head cover to the cylinder head.
  • at least one collar screw is used which has a shaft with a threaded portion, a head and spaced from the head a collar.
  • the respective collar screw is formed in one piece and has its components, ie the shaft, the threaded portion, the head and the collar, integrally.
  • the threaded portion is formed at a first end portion of the collar screw, while the head is formed at a second end portion of the collar screw.
  • the collar is formed on the shaft and there separates the threaded portion of a thread-free central portion extending from the collar to the head.
  • the respective collar screw with the threaded portion is screwed into a threaded opening formed on the cylinder head, wherein it is supported with the collar on the cylinder head, wherein it forms with its shaft, in particular with its central portion, by a formed on the intermediate flange Flansch matsö réelle and also extends through a formed on the cylinder head cover hood passage opening therethrough and wherein the collar screw is supported with its head on the cylinder head cover.
  • the respective collar screw clamps the cylinder head cover through the intermediate flange with the cylinder head, whereby the cylinder head cover is biased by the intermediate flange on the cylinder head.
  • a plurality of such collar bolts are provided, which are arranged distributed along the peripheral contour of the cylinder head cover and the intermediate flange.
  • the head can be supported directly and / or rigidly on the cylinder head cover in order to produce a direct power transmission here as well.
  • an indirect support on the cylinder head cover namely via an elastic element, e.g. an elastomeric disc to decouple also the support of the head on the cylinder head cover with respect to vibrations.
  • the intermediate flange in particular exclusively, indirectly, namely elastically supported by the elastic first seal assembly on the cylinder head.
  • the cylinder head cover in particular exclusively, indirectly, namely elastically supported by the elastic second seal assembly on the intermediate flange.
  • a distance between the cylinder head and the cylinder head cover may be greater than a height of the intermediate flange.
  • the intermediate flange is centered axially over the elastic sealing arrangements between the cylinder head and the cylinder head cover, that is to say parallel to the mounting direction or screwing direction, and is mounted elastically via the seal arrangements on the cylinder head and on the cylinder head cover.
  • the collar is positioned on the respective shoulder bolt in such a way that when mounting the collar bolt can be bolted to the collar against the cylinder head block, so then automatically the desired distance between the cylinder head cover and cylinder head is set.
  • the first seal assembly is formed by a single, closed along the intermediate flange circumferential first seal.
  • the second seal arrangement may be formed by a single, second closed around the intermediate flange second seal.
  • the first seal and the second seal may be identical.
  • the closed circumferential seals simplify assembly and result in an efficient seal between the cylinder head and the cylinder flange on the one hand and between the cylinder head cover and the intermediate flange on the other hand.
  • a corresponding, groove-shaped receiving chamber may be formed for the first seal on the intermediate flange or on the cylinder head.
  • a corresponding groove-shaped receiving chamber may be formed for the second seal on the cylinder flange or on the cylinder head cover.
  • the respective seal expediently separates an inner side of the intermediate flange from an outer side of the intermediate flange.
  • the respective collar screw is arranged on the outside, whereby the encapsulation of the interior and thus the sealing of the interior is not affected by the Flansch thoroughlygangsö Maschinentechnisch.
  • At least one securing region may be provided, in which the intermediate flange is secured exclusively on the cylinder head.
  • This fuse is designed so that it holds the intermediate flange on the cylinder head with removed collar bolts, so that the cylinder head cover can be removed while the intermediate flange can remain on the cylinder head.
  • the fuse is also designed so that it does not affect the vibratory end coupling of the intermediate flange of the cylinder head. This can be ensured, for example, by appropriate clearance axially and radially with respect to the mounting direction.
  • such a fuse can be realized by means of a screw which, although it produces a firm connection between the intermediate flange and the cylinder head, but has sufficient axial play and radial play that they in the assembled state for clamping the seal assemblies between the cylinder head cover and the intermediate flange or between the Intermediate flange and the cylinder head does not contribute.
  • the respective rigidly connected to the cylinder head collar screw itself can initiate no vibrations in the intermediate flange, a sufficient radial clearance is provided at least between the channel passage opening and the collar screw.
  • a corresponding radial play is provided for collar screw in the screw through hole to improve there in conjunction with the aforementioned elastic element a vibration decoupling between the cylinder head cover and collar screw.
  • the sealing arrangements advantageously act in each case axially, ie, parallel to the mounting direction or screwing direction.
  • Fig. 1 to 3 includes a here only partially shown internal combustion engine 1, which may be used in particular in a motor vehicle, a cylinder head 2, a cylinder head cover 3 and an intermediate flange 4.
  • the individual components are arranged with respect to.
  • the mounting direction 5 is arranged axially between the cylinder head 2 and the cylinder head cover 3.
  • the intermediate flange 4 forms a separate component with respect to the cylinder head cover 3 and with respect to the cylinder head 2.
  • a plurality of collar bolts 6 are provided which are distributed along the peripheral contour of the intermediate flange 4 and the cylinder head 3, respectively.
  • the collar bolts 6 are screwed parallel to the mounting direction 5, so that a screwing the mounting direction 5 corresponds, so that in the following also the screwing can be designated 5.
  • the respective collar screw 6 has a shank 7, which extends coaxially to a longitudinal center axis 8 of the collar screw 6, wherein the longitudinal center axis 8 in the mounted state is parallel to the screw 5. Furthermore, the collar screw 6 comprises a threaded portion 9, a head 10 and a collar 11, which is spaced from the head 10 and in particular the threaded portion 9 from the remaining shaft 7 separates.
  • first seal assembly 12 For the assembly of the cylinder head cover 3 and the intermediate flange 4 on the cylinder head 2, two seal assemblies, namely a first seal assembly 12 and a second seal assembly 13 are also provided.
  • the first sealing arrangement 12 is arranged between the cylinder head 2 and the intermediate flange 4.
  • the first seal assembly 12 is designed as an axial seal and acts accordingly axially, ie parallel to the screw 5 and mounting direction 5.
  • the second seal assembly 13 is disposed between the cylinder head cover 3 and the intermediate flange 4.
  • the second seal assembly 13 is also designed here as an axial seal, so that it also acts axially, ie parallel to the mounting direction 5.
  • the respective collar screw 6 is screwed to the threaded portion 9 in a threaded opening 14 which is formed on the cylinder head 2. Furthermore, the collar screw 6 is supported with its collar 11 on the cylinder head 2, namely at an opening 14 enclosing the threaded opening opening edge 15 axially, ie parallel to the screw longitudinal center axis 8 directly from.
  • the shaft 7 passes through a Flansch thoroughlygangsö réelle 16, which is formed in the intermediate flange 4, and a hood passage opening 17, which is formed in the cylinder head cover 3.
  • the head 10 is supported in the example shown indirectly indirectly on the cylinder head cover 3 from. While the collar 11 is supported rigidly and directly on the cylinder head 2, the head 10 is expediently indirectly supported on the cylinder head cover 3 via an elastic disk-shaped element 18.
  • the elastic member 18 can absorb vibrations.
  • such an elastic element 18 may be dispensed with.
  • vibrations from the cylinder head 2 via the respective collar screw 6 can be transferred to the cylinder head cover 3.
  • this vibration transmission can be negligible in certain designs due to the relatively small contact points between the cylinder head cover 3 and the respective screw head 10.
  • the collar bolts 6 are designed so that they cause no interlock between the intermediate flange 4 and the cylinder head 2 on the one hand and between the intermediate flange 4 and the cylinder head cover 3 on the other hand, so that the intermediate flange 4 thus touches neither the cylinder head 2 nor the cylinder head cover 3 directly axially.
  • This is achieved by indirectly supporting the intermediate flange 4 indirectly on the cylinder head cover 3 via the first sealing arrangement 12 indirectly on the cylinder head 2 and via the second sealing arrangement 13.
  • both seal assemblies 12,13 are designed to be elastic, so that the intermediate flange 4 is elastically supported both on the cylinder head 2 and on the cylinder head cover 3.
  • the vote of the collar bolts 6 on the associated components of the internal combustion engine 1, ie cylinder head 2, cylinder head cover 3 and intermediate flange 4, is suitably such that a measured in the mounting direction 5 distance 19 between the cylinder head 2 facing bottom 20 of the cylinder head cover 3 and a the cylinder head cover 3 facing top 21 of the cylinder head 2 is greater than a height 22 of the intermediate flange 4, which is measured in the mounting direction 5 between the cylinder head 2 facing bottom 23 of the intermediate flange 4 and a cylinder head cover 3 facing top 24 of the intermediate flange 4.
  • Due to the elasticities of the two seal assemblies 12,13 of the intermediate flange. 4 axially centered between the cylinder head 2 and the cylinder head cover 3.
  • the intermediate flange 4 by the elastic seal assemblies 12,13 axially and transversely thereto, so stored radially elastic and movable on the cylinder head 2 and on the cylinder head cover 3.
  • the first sealing arrangement 12 is preferably formed by a single first seal, which runs closed around the intermediate flange 4 and which is also referred to below as 12.
  • the second seal assembly 13 is formed by a single, closed along the intermediate flange 4 circumferential second seal, which is also referred to below with 13.
  • the first seal 12 is chambered in the example shown on the intermediate flange 4 and axially supported on the upper side 21 of the cylinder head 2.
  • the second seal 13 is chambered in the example on the cylinder head cover 3 and axially supported on the upper side 24 of the intermediate flange 4.
  • the seals 12,13 are arranged so that they separate an inner side 25 of the intermediate flange 4 from an outer side 26 of the intermediate flange 4. It is noteworthy that the collar screws 6 are arranged on the outside 26. Accordingly, the Flansch thoroughlygangsö réelleen 16 also extend through the outer side 26 of the connecting flange 4, which significantly simplifies the sealing of the inner side 25 of the connecting flange 4.
  • Corresponding Fig. 1 can be arranged in a region 27 a locking screw, not shown here, with the aid of the intermediate flange 4 can be secured to the cylinder head 2.
  • the area 27 is therefore also referred to below as the backup area 27. It is clear that a plurality of such securing regions 27 can be provided along the circumference of the intermediate flange 4.
  • the screw is done such that the vibration decoupling and thus in particular the elasticity and mobility between the intermediate flange 4 and cylinder head 2 is not hindered. This can be realized by a corresponding axial and radial clearance of the screw in the respective fuse area 27.
