Definitions

  • Actuator of a sliding cam system with at least one sliding cam and with at least one slidable in an actuator guide Aktorit, wherein the Aktorvorides on a component of a cylinder head or on the cylinder head of a Hubkolbenbrennkraftmaschine is fastened and Aktortors is contacted by moving out of the Aktor Entry with at least one groove of the sliding cam system and wherein the actuator pin communicates with a displaceable anchor rod secured to an armature and is spring biased toward the anchor rod and the armature is governed by an electrical coil.
  • Such a generic actuator device is known from DE-102 40 774 A1, Figure 2.
  • Starting from the retracted inner layer of Aktor starts activating the Aktor restartes by energizing a coil, wherein an electric field is generated, which activates an armature.
  • the armature which is connected to an anchor rod, moves the actuator pin out of the actuator guide so that it can contact a slot of a sliding cam system.
  • the armature displaces the armature rod and the actuator pin against the force of a spring loading the actuator pin towards the spool.
  • the armature rod attached to the armature is guided over the armature, which is mounted in a yoke element, so that the anchor rod, which is indeed arranged in a coil core, can absorb any significant lateral forces.
  • the Aktorstatt and thus the spring force are based directly on the anchor rod and thus on the anchor, so that the limitation of the spring caused by the movement of the Aktortors is given by the anchor and its limitation.
  • An exact fixation of the actuator device on a component of a cylinder head or on the cylinder head is also not defined. However, this is of great importance so that the Aktorstatt can sufficiently engage in the groove of the sliding cam system and then can move out of the groove again, without having too large a distance at the next to the groove arranged high circle of the cam system.
  • the object of the invention is therefore to improve an actuator device with the features described above so that an exact fixation of the actuator device can be done on the component or the cylinder head of a reciprocating internal combustion engine, that an exact positioning of the Aktorstattes is given in its inner position and that too two coils with anchor and anchor rod can be arranged side by side, without predetermining or influencing the positions of the also juxtaposed Aktorite.
  • the object of the invention is achieved in that the actuator guide is fixed to a mounting flange. It is preferably operatively connected to a transition housing secured to the mounting flange. This results in an exact alignment of the actuator device on the component of the cylinder head or the cylinder head of an internal combustion engine.
  • the transition housing may be designed as a separate component to which then the actuator device is attached, but it can also be made in one piece with the actuator guide.
  • the coil and the anchor rod are mounted on a spool core and that the spool core has a shoulder which is guided in an opening of the mounting flange. This results in an exact alignment of the bobbin on the mounting flange and against the actuator guide.
  • the coil and the armature are enclosed by a lid, which is also in communication with the connecting flange, wherein at the anchor, adjacent to the lid, a disc is attached.
  • This disc can be made individually or in one piece with the anchor and is made of magnetizable material.
  • This disc or magnetic disk improves the voltage signal for evaluating the position of the Aktorstattes. Namely, the disk produces a large change in lifting from the spool.
  • the cover, the mounting flange and the transition housing associated openings or holes have, in which jacks are clamped.
  • the bushes serve as a fixation, thereby making available an actuator device designed as a unit, which is fastened to the component or cylinder head only by means of screws which can be guided through the bushes.
  • the anchor rod is connected to a spring guide with spring cover in connection, which in turn is attached to the Aktorstatt.
  • the spring cover can be supported on a stop disc, wherein the stop disc is connected to the actuator guide or with the transition housing.
  • the actuator pin (s) has an exact inner position in the actuator guide.
  • the anchor rod can be connected directly or with the interposition of a pressure plate with the spring guide.
  • the pressure plate is then attached to the anchor rod. This is possible because the anchor rod is well guided on the spool core. If two solenoid units with coils, anchors, anchor rods and coil cores are fixed next to each other on the mounting flange, the actuator pins can be arranged arbitrarily side by side, since the pressure plates allow an axial offset to the respective anchor rod.

  • FIGS. 1 and 2 designates an actuator pin, which is displaceably mounted in an actuator guide 2.

  • a spring 5 is arranged, which loads the actuator pin 1 in the direction of an electromagnet unit 15 which will be described below.
  • a stop plate 6 is fixed, which limits the movement of the Aktortorses 1 inwardly characterized in that the stop plate 6 forms a stop for the spring cover 4.

  • the mounting flange 8 is formed as a plate and has according to Figure 1, an opening or two openings according to Figure 2, in which paragraphs 9 are inserted, which are part of a spool core 10.
  • each an anchor rod is axially displaceably mounted, which is connected at its upper end with an armature 12 which has a disc 13 at its end facing away from the anchor rod 1 1 end.

  • the transition housing 7, the mounting flange 8 and the lid 16 have openings or holes which are aligned with each other, so that in these openings bushings 17 are fitted, which ensure an exact guidance of the individual components to each other and define a structural unit.
