Definitions

  • the invention relates to an internal combustion engine comprising a cylinder head with bearing lanes for the storage of camshafts and at least one associated with the cylinder head accessory. Furthermore, the invention relates to a method for producing such an internal combustion engine.
  • From the DE 196 24 240 A1 is an internal combustion engine with the front side of the cylinder head, arranged in extension of the camshaft pumps known.
  • the pumps each have a flange with which they are attached to the cylinder head. So an additional parting line is formed, which must be sealed separately.
  • it is problematic to edit the bearing lanes for receiving the camshaft and the pump intake so accurate that the required for the pump interface specifications are achieved. For this reason, according to the DE 196 24 240 A1 Slider clutches provided.
  • the object of the invention is therefore to develop an aforementioned internal combustion engine so that additional joints are avoided, a process-reliable and highly accurate assignment of camshafts and at least one accessory is guaranteed and a simplified assembly and a component reduction can be achieved.
  • a structurally separate bearing plate is provided, which also fulfills a flange function for the at least one accessory and with a method having the features of claim 6, in which Cylinder head and the bearing plate first processed separately and then joined together.
  • Particularly preferred embodiments and further developments of the invention are the subject of the dependent claims. It is particularly advantageous if the flange-forming end shield and a housing of the auxiliary unit are integrally formed integrally. Alternatively, the flange-forming end shield and a housing of the auxiliary unit can be non-positively and / or positively connected with each other.
  • the at least one accessory is a pump driven by a camshaft.
  • a particularly preferred embodiment of the method according to the invention is characterized in that the separate processing of the bearing plate comprises the production of an assembly bearing plate / accessory.
  • a cylinder head 100 of an internal combustion engine not shown here has two bearing lanes 102, 104 for supporting an intake and an exhaust camshaft.
  • a structurally separate bearing plate 106 is connected to the cylinder head 100.
  • the bearing plate 106 is screwed to the cylinder head 100, indicated in the drawing by bores 103.
  • the bearing plate 106 has two openings for further storage of the camshafts, wherein in the illustration only one opening 108 is visible, the other opening is from the housing 112 of a pump 110 hidden.
  • a pump 110 Connected to the bearing plate 106 is the housing 112 of a pump 110.
  • This may be a delivery pump, which may be designed, for example, as a gear pump, a high-pressure pump, which may be in the form of a piston pump or a vacuum pump.
  • the pump may be part of a fuel supply system of the internal combustion engine or provide a vacuum required for braking force assistance.
  • the Lagergasse 102 associated pump 110 is shown in the figure, of course, according to the invention, a further, the Lagergasse 104 associated pump can be provided.
  • the housing 112 of the pump 110 and the bearing plate 106 are integrally formed cohesively, the bearing plate 106 also forms a mounting flange of the pump 110.
  • the bearing plate 106 and the housing 112 of the pump 110 are non-positively and / or positively connected to each other, for example, by the housing 112 is placed on the bearing plate 106 and bolted from the inside to the bearing plate 106.
  • the bearing plate 106 and the housing 112 of the pump 110 can be glued together, welded, soldered or pressed. If necessary, provide a seal between bearing plate 106 and accessory 110.
  • the bearing plate 106 forms a mounting flange of the pump 110, a always required in known constructions separate pump flange is superfluous. In this way, space and material can be saved, the assembly is simplified. In addition, the number of components is reduced and the seal between the cylinder head 100 and bearing plate / pump 106/110 must not survive the stresses of chemical, thermal and / or mechanical nature of further processing of the cylinder head 100 and / or the bearing plate 106 and therefore can be targeted be adapted to the requirements of the tightness. The sealing of the cylinder head 100 can be made more robust.
