Definitions

  • the invention relates to a cylinder head for an internal combustion engine with a variable stroke valve train according to the features in the preamble of the claim 1.
  • valve drive device for variable stroke adjustment a gas exchange valve of an internal combustion engine described.
  • Valve train device is the gas exchange valve with the interposition of a Transmission element with a movable about a rotation axis roller in operative connection with a control path comprising a no-lift curve and a lift curve, in an end region of a stroke for the gas exchange valve of a cam of a camshaft controlled pivot lever is arranged.
  • Object of the present invention is therefore, the backdrop as stiff as possible in the to integrate variable stroke valve train.
  • An embodiment according to claim 2 includes two technological variants the assembly of the scenery on the cylinder head. So the variant offers a detachable Compound, e.g. a screw, especially manufacturing advantages in terms of cost and simplicity in making the overall system. In contrast, offers the variant of pouring the scenery in the cylinder head an even higher manufacturing precision, since the finishing after the Pouring done.
  • a detachable Compound e.g. a screw
  • the embodiment according to claim 5 also reduces the production costs or the installation effort and thus the installation costs.
  • the manufacturing possibilities of the backdrop according to claim 6 ensure the Operation of the variable stroke valve train good wear characteristics, since the scenery made of a harder material than the cylinder head. In addition, it is the production as a sintered component cost and in relation to the selected Material designed for optimum wear resistance.
  • Fig. 1 shows a variable-stroke valve drive 2, which is shown in a rudimentary manner Cylinder head 1 is arranged.
  • the variable stroke valve train 2 consists essentially from a pivot lever 3, with a roller element 4 and a swing fulcrum 4 ', and a gate 5 with a slide track 5', an intermediate element 7, a gas exchange valve 8, a cam 9, which is arranged on a camshaft 9 ' is and a spring 10 and an adjusting device 11.
  • the backdrop 5 is stationary poured into the cylinder head 1.
  • the pivot lever 3 is supported on the one hand via the roller element 4 on the slide track 5 'of the link 5 from and the other with a control track 6, which consists of a Leerhubkurve 6 'and a lift curve 6 " on the intermediate element 7 from.
  • the intermediate element 7 is a roller cam follower, whose role is rotatable about a rotation axis 12.
  • the rotation axis 12 is also the center of the slide track 5 'in a Nullhub ein.
  • the Intermediate element is supported on the one hand by the axis of rotation 12 on a clearance compensation element 14, here a hydraulic valve clearance compensation element, and on the other hand on the gas exchange valve 8 from. Between the control track 6 and the first roller element 4 is on the pivot lever 3 another roller element thirteenth arranged.
  • Fig. 2 shows a three-dimensional view of the cast in a cylinder head 1 Gate 5 with the adjusting device 11, on which the first roller element 4 on the one hand and on the slide track 5 'on the other hand supported. Shown is a staggered in Nockenwellenachscardi double arrangement, of which only is addressed in more detail to the reader facing arrangement. Furthermore, in approximately centrally in the pivot lever 3, the second roller element 13 can be seen, which is supported on the cam 9 of the camshaft shown 9 'shown.
  • the backdrop 5 poured directly into the cylinder head 1. It is thus an integral part of the cylinder head 1.
  • a detachable connection such as a screw, conceivable.
  • the gate 5 is made of a sintered material, but it can also be produced by forging or casting.
  • the cylinder head 1 is preferably made of a light metal alloy.
  • This backdrop block is used either for a cylinder of Not shown internal combustion engine or for all cylinders simultaneously as Backing 5.
  • the set blocks can also be forged, cast or sintered be.
  • the attachment in the cylinder head 1 is analogous to the attachment of a single Gate 5 in the cylinder head 1.
